To bridge the gap between Earth science teachers, librarians, scientists and data archive managers, we have started the ERESE project that will create, archive and make available "Enduring Resources in Earth Science Education" through information technology (IT) portals. In the first phase of this National Science Digital Library (NSDL) project, we are focusing on the development of these ERESE resources for middle and high school teachers to be used in lesson plans with "plate tectonics" and "magnetics" as their main theme. In this presentation, we will show how these new ERESE resources are being generated, how they can be uploaded via online web wizards, how they are archived, how we make them available via the EarthRef.org Digital Archive (ERDA) and Reference Database (ERR), and how they relate to the SIOExplorer database containing data objects for all seagoing cruises carried out by the Scripps Institution of Oceanography. The EarthRef.org web resource uses the vision of a "general description" of the Earth as a geological system to provide an IT infrastructure for the Earth sciences. This emphasizes the marriage of the "scientific process" (and its results) with an educational cyber-infrastructure for teaching Earth sciences, on any level, from middle school to college and graduate levels. Eight different databases reside under EarthRef.org from which ERDA holds any digital object that has been uploaded by other scientists, teachers and students for free, while the ERR holds more than 80,000 publications. For more than 1,500 of these publications, this latter database makes available for downloading JPG/PDF images of the abstracts, data tables, methods and appendices, together with their digitized contents in Microsoft Word and Excel format. Both holdings are being used to store the ERESE objects that are being generated by a group of undergraduate students majoring in Environmental Systems (ESYS) program at the UCSD with an emphasis on the Earth Sciences. These students perform library and internet research in order to design and generate these "Enduring Resources in Earth Science Education" that they test by closely interacting with the research faculty at the Scripps Institution of Oceanography. Typical ERESE resources can be diagrams, model cartoons, maps, data sets for analyses, and glossary items and essays to explain certain Earth Science concepts and are ready to be used in the classroom.

Increasing Participation in the Earth Sciences A 35 year Journey

NASA Astrophysics Data System (ADS)

Blueford, J. R.

2006-12-01

In the 1970's the fact that woman and ethnic minorities men made up approximately10% of the workforce in the geosciences created concern. Determining ways to increase the participation became a topic of discussion amongst many of the geosciences agencies in the United States. Many created scholarships and work opportunities for students. One of the most successful projects was the MPES (Minority Participation in the Earth Science) Program implemented by the U.S. Geological Survey. A key factor in its success was its outreach programs which used employees to work in elementary schools to get children excited about earth sciences. Successive years added teacher workshops and developing career day presentations to help school districts increase the awareness of the earth sciences. However, cutbacks prevented the continuation of these programs, but from the ashes a new non-profit organization of scientists, the Math Science Nucleus, developed curriculum and implementation strategies that used Earth Sciences as a core content area. Using the power of the internet, it provided teachers and parents around the world content driven curriculum. The Integrating Science, Math, and Technology Reference Curriculum is used around the world to help teachers understand how children learn science content.

Using News Media Databases (LexisNexis) To Identify Relevant Topics For Introductory Earth Science Classes

NASA Astrophysics Data System (ADS)

Cervato, C.; Jach, J. Y.; Ridky, R.

2003-12-01

Introductory Earth science courses are undergoing pedagogical changes in universities across the country and are focusing more than ever on the non-science majors. Increasing enrollment of non-science majors in these introductory Earth science courses demands a new look at what is being taught and how the content can be objectively chosen. Assessing the content and effectiveness of these courses requires a quantitative investigation of introductory Earth science topics and their relevance to current issues and concerns. Relevance of Earth science topics can be linked to improved students' attitude toward science and a deeper understanding of concepts. We have used the Internet based national news search-engine LexisNexis Academic Universe (http://www.lexisnexis.org/) to select the occurrence of Earth science terms over the last 12 months, five and ten years both regionally and nationally. This database of term occurrences is being used to examine how Earth sciences have evolved in the news through the last 10 years and is also compared with textbook contents and course syllabi from randomly selected introductory earth science courses across the nation. These data constitute the quantitative foundation for this study and are being used to evaluate the relevance of introductory earth science course content. The relevance of introductory course content and current real-world issues to student attitudes is a crucial factor when considering changes in course curricula and pedagogy. We have examined students' conception of the nature of science and attitudes towards science and learning science using a Likert-scale assessment instrument in the fall 2002 Geology 100 classes at Iowa State University. A pre-test and post-test were administered to see if the students' attitudes changed during the semester using as reference a control group comprised of geoscience undergraduate and graduate students, and faculty. The results of the attitude survey have been analyzed in terms of student demographics and socioeconomic variables (e.g., year in school, gender).

EarthRef.org: Exploring aspects of a Cyber Infrastructure in Earth Science and Education

NASA Astrophysics Data System (ADS)

Staudigel, H.; Koppers, A.; Tauxe, L.; Constable, C.; Helly, J.

2004-12-01

EarthRef.org is the common host and (co-) developer of a range of earth science databases and IT resources providing a test bed for a Cyberinfrastructure in Earth Science and Education (CIESE). EarthRef.org data base efforts include in particular the Geochemical Earth Reference Model (GERM), the Magnetics Information Consortium (MagIC), the Educational Resources for Earth Science Education (ERESE) project, the Seamount Catalog, the Mid-Ocean Ridge Catalog, the Radio-Isotope Geochronology (RiG) initiative for CHRONOS, and the Microbial Observatory for Fe oxidizing microbes on Loihi Seamount (FeMO; the most recent development). These diverse databases are developed under a single database umbrella and webserver at the San Diego Supercomputing Center. All the data bases have similar structures, with consistent metadata concepts, a common database layout, and automated upload wizards. Shared resources include supporting databases like an address book, a reference/publication catalog, and a common digital archive making database development and maintenance cost-effective, while guaranteeing interoperability. The EarthRef.org CIESE provides a common umbrella for synthesis information as well as sample-based data, and it bridges the gap between science and science education in middle and high schools, validating the potential for a system wide data infrastructure in a CIESE. EarthRef.org experiences have shown that effective communication with the respective communities is a key part of a successful CIESE facilitating both utility and community buy-in. GERM has been particularly successful at developing a metadata scheme for geochemistry and in the development of a new electronic journal (G-cubed) that has made much progress in data publication and linkages between journals and community data bases. GERM also has worked, through editors and publishers, towards interfacing databases with the publication process, to accomplish a more scholarly and database friendly data publication environment, and to interface with the respective science communities. MagIC has held several workshops that have resulted in an integrated data archival environment using metadata that are interchangeable with the geochemical metadata. MagIC archives a wide array of paleo and rock magnetic directional, intensity and magnetic property data as well as integrating computational tools. ERESE brought together librarians, teachers, and scientists to create an educational environment that supports inquiry driven education and the use of science data. Experiences in EarthRef.org demonstrates the feasibility of an effective, community wide CIESE for data publication, archival and modeling, as well as the outreach to the educational community.

Wysession, M.; Ladue, N.; Budd, D.; Campbell, K.; Conklin, M.; Lewis, G.; Raynolds, R.; Ridky, R.; Ross, R.; Taber, J.; Tewksbury, B.; Tuddenham, P.

2008-12-01

During 2008, the Earth Sciences Literacy Initiative (ESLI) constructed a framework of earth science "Big Ideas" and "Supporting Concepts". Following the examples of recent literacy efforts in the ocean, atmosphere and climate research communities, ESLI has distilled the fundamental understandings of the earth science community into a document that all members of the community will be able to refer to when working with educators, policy-makers, the press and members of the general public. This document is currently in draft form for review and will be published for public distribution in 2009. ESLI began with the construction of an organizing committee of a dozen people who represent a wide array of earth science backgrounds. This group then organized and ran two workshops in 2008: a 2-week online content workshop and a 3-day intensive writing workshop. For both workshops, participants were chosen so as to cover the full breadth of earth science related to the solid earth, surficial processes, and fresh-water hydrology. The asynchronous online workshop included 350 scientists and educators participating from around the world and was a powerful way to gather ideas and information while retaining a written record of all interactions. The writing workshop included 35 scientists, educators and agency representatives to codify the extensive input of the online workshop. Since September, 2008, drafts of the ESLI literacy framework have been circulated through many different channels to make sure that the document accurately reflects the current understandings of earth scientists and to ensure that it is widely accepted and adopted by the earth science communities.

The Global Geodetic Observing System: Recent Activities and Accomplishments

NASA Astrophysics Data System (ADS)

Gross, R. S.

2017-12-01

The Global Geodetic Observing System (GGOS) of the International Association of Geodesy (IAG) provides the basis on which future advances in geosciences can be built. By considering the Earth system as a whole (including the geosphere, hydrosphere, cryosphere, atmosphere and biosphere), monitoring Earth system components and their interactions by geodetic techniques and studying them from the geodetic point of view, the geodetic community provides the global geosciences community with a powerful tool consisting mainly of high-quality services, standards and references, and theoretical and observational innovations. The mission of GGOS is: (a) to provide the observations needed to monitor, map and understand changes in the Earth's shape, rotation and mass distribution; (b) to provide the global frame of reference that is the fundamental backbone for measuring and consistently interpreting key global change processes and for many other scientific and societal applications; and (c) to benefit science and society by providing the foundation upon which advances in Earth and planetary system science and applications are built. The goals of GGOS are: (1) to be the primary source for all global geodetic information and expertise serving society and Earth system science; (2) to actively promote, sustain, improve, and evolve the integrated global geodetic infrastructure needed to meet Earth science and societal requirements; (3) to coordinate with the international geodetic services that are the main source of key parameters and products needed to realize a stable global frame of reference and to observe and study changes in the dynamic Earth system; (4) to communicate and advocate the benefits of GGOS to user communities, policy makers, funding organizations, and society. In order to accomplish its mission and goals, GGOS depends on the IAG Services, Commissions, and Inter-Commission Committees. The Services provide the infrastructure and products on which all contributions of GGOS are based. The IAG Commissions and Inter-Commission Committees provide expertise and support for the scientific development within GGOS. In summary, GGOS is IAG's central interface to the scientific community and to society in general. Recent activities and accomplishments of the Global Geodetic Observing System will be presented.

NASA is studying a coordinated effort called the Mission to Planet Earth to understand global change. The goals are to understand the Earth as a system, and to determine those processes that contribute to the environmental balance, as well as those that may result in changes. The Earth Observing System (Eos) is the centerpiece of the program. Eos will create an integrated scientific observing system that will enable multidisciplinary study of the Earth including the atmosphere, oceans, land surface, polar regions, and solid Earth. Science goals, the Eos data and information system, experiments, measuring instruments, and interdisciplinary investigations are described.

Creating a FIESTA (Framework for Integrated Earth Science and Technology Applications) with MagIC

NASA Astrophysics Data System (ADS)

Minnett, R.; Koppers, A. A. P.; Jarboe, N.; Tauxe, L.; Constable, C.

2017-12-01

The Magnetics Information Consortium (https://earthref.org/MagIC) has recently developed a containerized web application to considerably reduce the friction in contributing, exploring and combining valuable and complex datasets for the paleo-, geo- and rock magnetic scientific community. The data produced in this scientific domain are inherently hierarchical and the communities evolving approaches to this scientific workflow, from sampling to taking measurements to multiple levels of interpretations, require a large and flexible data model to adequately annotate the results and ensure reproducibility. Historically, contributing such detail in a consistent format has been prohibitively time consuming and often resulted in only publishing the highly derived interpretations. The new open-source (https://github.com/earthref/MagIC) application provides a flexible upload tool integrated with the data model to easily create a validated contribution and a powerful search interface for discovering datasets and combining them to enable transformative science. MagIC is hosted at EarthRef.org along with several interdisciplinary geoscience databases. A FIESTA (Framework for Integrated Earth Science and Technology Applications) is being created by generalizing MagIC's web application for reuse in other domains. The application relies on a single configuration document that describes the routing, data model, component settings and external services integrations. The container hosts an isomorphic Meteor JavaScript application, MongoDB database and ElasticSearch search engine. Multiple containers can be configured as microservices to serve portions of the application or rely on externally hosted MongoDB, ElasticSearch, or third-party services to efficiently scale computational demands. FIESTA is particularly well suited for many Earth Science disciplines with its flexible data model, mapping, account management, upload tool to private workspaces, reference metadata, image galleries, full text searches and detailed filters. EarthRef's Seamount Catalog of bathymetry and morphology data, EarthRef's Geochemical Earth Reference Model (GERM) databases, and Oregon State University's Marine and Geology Repository (http://osu-mgr.org) will benefit from custom adaptations of FIESTA.

Journal of Geophysical Research Publications: Community Characteristics

NASA Astrophysics Data System (ADS)

Pfirman, S. L.; Porter, A.

2009-12-01

Do earth science publications differ by subfield or gender? To figure this out we analyzed publications in JGR Atmosphere, Oceans, and Solid Earth for the year 2000. We assumed that the first author exerted controlling influence over publication characteristics and then we looked at the number of co-authors, number of institutions represented by co-author affiliations, page length of the article, number of references cited, number of subject categories represented in the cited references, number of times the article was cited, and the time between the date the article was submitted and the date when it was accepted for publication. We found that, within each field, there was remarkable similarity between the publications led by women and those led by men. Interesting differences showed up between subfields: for example, Solid Earth authors use more references than do authors publishing in Atmosphere or Oceans.

A long time span relativistic precession model of the Earth

NASA Astrophysics Data System (ADS)

Tang, Kai; Soffel, Michael H.; Tao, Jin-He; Han, Wen-Biao; Tang, Zheng-Hong

2015-04-01

A numerical solution to the Earth's precession in a relativistic framework for a long time span is presented here. We obtain the motion of the solar system in the Barycentric Celestial Reference System by numerical integration with a symplectic integrator. Special Newtonian corrections accounting for tidal dissipation are included in the force model. The part representing Earth's rotation is calculated in the Geocentric Celestial Reference System by integrating the post-Newtonian equations of motion published by Klioner et al. All the main relativistic effects are included following Klioner et al. In particular, we consider several relativistic reference systems with corresponding time scales, scaled constants and parameters. Approximate expressions for Earth's precession in the interval ±1 Myr around J2000.0 are provided. In the interval ±2000 years around J2000.0, the difference compared to the P03 precession theory is only several arcseconds and the results are consistent with other long-term precession theories. Supported by the National Natural Science Foundation of China.

Stepping Stones: Evolving the Earth and Its Life

NASA Astrophysics Data System (ADS)

McKay, Christopher P.

In recent years, science has begun to consider more system-level studies that cross disciplines. These studies challenge our traditional disciplinary training. It is no longer enough to be just a geologist when the problems of interest deal with an entire planet. Indeed, a knowledge of biology, geology astronomy, and myriad subfields is needed. In Stepping Stones, Stephen Drury steps up to the daunting task of writing a general treatment of the science of the entire Earth. He not only ranges through all of the relevant physical sciences but also reaches to economics and political theory. The material is presented at a general level with reading lists but no specific references. Equations have been minimized.

ESSG-based global spatial reference frame for datasets interrelation

NASA Astrophysics Data System (ADS)

Yu, J. Q.; Wu, L. X.; Jia, Y. J.

2013-10-01

To know well about the highly complex earth system, a large volume of, as well as a large variety of, datasets on the planet Earth are being obtained, distributed, and shared worldwide everyday. However, seldom of existing systems concentrates on the distribution and interrelation of different datasets in a common Global Spatial Reference Frame (GSRF), which holds an invisble obstacle to the data sharing and scientific collaboration. Group on Earth Obeservation (GEO) has recently established a new GSRF, named Earth System Spatial Grid (ESSG), for global datasets distribution, sharing and interrelation in its 2012-2015 WORKING PLAN.The ESSG may bridge the gap among different spatial datasets and hence overcome the obstacles. This paper is to present the implementation of the ESSG-based GSRF. A reference spheroid, a grid subdvision scheme, and a suitable encoding system are required to implement it. The radius of ESSG reference spheroid was set to the double of approximated Earth radius to make datasets from different areas of earth system science being covered. The same paramerters of positioning and orienting as Earth Centred Earth Fixed (ECEF) was adopted for the ESSG reference spheroid to make any other GSRFs being freely transformed into the ESSG-based GSRF. Spheroid degenerated octree grid with radius refiment (SDOG-R) and its encoding method were taken as the grid subdvision and encoding scheme for its good performance in many aspects. A triple (C, T, A) model is introduced to represent and link different datasets based on the ESSG-based GSRF. Finally, the methods of coordinate transformation between the ESSGbased GSRF and other GSRFs were presented to make ESSG-based GSRF operable and propagable.

Earth Science Microwave Remote Sensing at NASA's Goddard Space Flight Center

Kim, Edward; Busalacchi, Antonio J. (Technical Monitor)

2000-01-01

The Goddard Space Flight Center (GSFC) was established as NASA's first space flight center in 1959. Its 12,000 personnel are active in the Earth and space sciences, astronomy, space physics, tracking and communications. GSFC's mission is to expand our knowledge of the Earth and its environment, the solar system, and the universe through observations from space. The main Goddard campus is located in Greenbelt, Maryland, USA, just north of Washington, D.C. The Wallops Flight Facility (operational since 1945), located on the Atlantic coast of Virginia was consolidated with the Goddard Space Flight Center in 1982. Wallops is now NASA's principal facility for management and implementation of suborbital research programs, and supports a wide variety of airborne science missions as well. As the lead Center for NASA's Earth Science Enterprise (ESE)--a long-term, coordinated research effort to study the Earth as a global environmental system--GSFC scientists and engineers are involved in a wide range of Earth Science remote sensing activities. Their activities range from basic geoscience research to the development of instruments and technology for space missions, as well as the associated Calibration/Validation (Cal/Val) work. The shear breadth of work in these areas precludes an exhaustive description here. Rather, this article presents selected brief overviews of microwave-related Earth Science applications and the ground-based, airborne, and space instruments that are in service, under development, or otherwise significantly involving GSFC. Likewise, contributing authors are acknowledged for each section, but the results and projects they describe represent the cumulative efforts of many persons at GSFC as well as at collaborating institutions. For further information, readers are encouraged to consult the listed websites and references.

The macroecology of sustainability

Burger, Joseph R.; Allen, Craig D.; Brown, James H.; Burnside, William R.; Davidson, Ana D.; Fristoe, Trevor S.; Hamilton, Marcus J.; Mercado-Silva, Norman; Nekola, Jeffrey C.; Okie, Jordan G.; Zuo, Wenyun

2012-01-01

The discipline of sustainability science has emerged in response to concerns of natural and social scientists, policymakers, and lay people about whether the Earth can continue to support human population growth and economic prosperity. Yet, sustainability science has developed largely independently from and with little reference to key ecological principles that govern life on Earth. A macroecological perspective highlights three principles that should be integral to sustainability science: 1) physical conservation laws govern the flows of energy and materials between human systems and the environment, 2) smaller systems are connected by these flows to larger systems in which they are embedded, and 3) global constraints ultimately limit flows at smaller scales. Over the past few decades, decreasing per capita rates of consumption of petroleum, phosphate, agricultural land, fresh water, fish, and wood indicate that the growing human population has surpassed the capacity of the Earth to supply enough of these essential resources to sustain even the current population and level of socioeconomic development.

Musings about the word “absolute” in Earth science literature

NASA Astrophysics Data System (ADS)

Duffield, Wendell A.

Rather than face the prospect of old age and retirement sometimes disturbed by the niggling feeling that I should have said something earlier, here is a public statement about a pet peeve concerning the use, if not the abuse and misuse, of the word absolute as it appears in a variety of Earth science literature. The triggering event for taking action, after a couple of decades of inaction, was seeing yet another title of the sort “The Absolute Age of the… Volcanic Rock”, combined with a little too much spare time during evenings in a lonely, isolated field camp.Because my interests are principally in magmatic systems and secondarily in global plate tectonics, I see absolute used mostly with reference to the ages of igneous rocks and to the motions of lithospheric plates. People in other fields of Earth science surely will think of their own examples.

Ancient and Medieval Earth in Armenia

NASA Astrophysics Data System (ADS)

Farmanyan, S. V.

2015-07-01

Humankind has always sought to recognize the nature of various sky related phenomena and tried to give them explanations. The purpose of this study is to identify ancient Armenians' pantheistic and cosmological perceptions, world view, notions and beliefs related to the Earth. The paper focuses on the structure of the Earth and many other phenomena of nature that have always been on a major influence on ancient Armenians thinking. In this paper we have compared the term Earth in 31 languages. By discussing and comparing Universe structure in various regional traditions, myths, folk songs and phraseological units we very often came across to "Seven Heavens" (Seven heavens is a part of religious cosmology found in many major religions such as Islam, Judaism, Hinduism and Christianity (namely Catholicism) and "Seven Earths". Armenians in their turn divided Earth and Heavens into seven layers. And in science too, both the Earth and the Heavens have 7 layers. The Seven Heavens refer to the layers of our atmosphere. The Seven Earths refer to the layers of the Earth (from core to crust), as well as seven continents. We conclude that the perception of celestial objects varies from culture to culture and preastronomy had a significant impact on humankind, particularly on cultural diversities.

Assessing Current State Science Teaching and Learning Standards for Ability to Achieve Climate Science Literacy

NASA Astrophysics Data System (ADS)

Busch, K. C.

2012-12-01

Even though there exists a high degree of consensus among scientists about climate change, doubt has actually increased over the last five years within the general U.S. public. In 2006, 79% of those polled agreed that there is evidence for global warming, while only 59% agreed in 2010 (Pew Research Center, 2010). The source for this doubt can be partially attributed to lack of knowledge. Formal education is one mechanism that potentially can address inadequate public understanding as school is the primary place where students - and future citizens - learn about the climate. In a joint effort, several governmental agencies, non-governmental organizations, scientists and educators have created a framework called The Essential Principles of Climate Science Literacy, detailing seven concepts that are deemed vital for individuals and communities to understand Earth's climate system (USGCRP, 2009). Can students reach climate literacy - as defined by these 7 concepts - if they are taught using a curriculum based on the current state standards? To answer this question, the K-12 state science teaching and learning standards for Texas and California - two states that heavily influence nation-wide textbook creation - were compared against the Essential Principles. The data analysis consisted of two stages, looking for: 1) direct reference to "climate" and "climate change" and 2) indirect reference to the 7 Essential Principles through axial coding. The word "climate" appears in the California K-12 science standards 4 times and in the Texas standards 7 times. The word "climate change" appears in the California and Texas standards only 3 times each. Indirect references to the 7 Essential Principles of climate science literacy were more numerous. Broadly, California covered 6 of the principles while Texas covered all 7. In looking at the 7 principles, the second one "Climate is regulated by complex interactions among component of the Earth system" was the most substantively addressed. Least covered were number 6 "Human activities are impacting the climate system" and number 7 "Climate change will have consequences for the Earth system and human lives." Most references, either direct or indirect, occurred in the high school standards for earth science, a class not required for graduation in either state. This research points to the gaps between what the 7 Essential Principles of Climate Literacy defines as essential knowledge and what students may learn in their K-12 science classes. Thus, the formal system does not seem to offer an experience which can potentially develop a more knowledgeable citizenry who will be able to make wise personal and policy decisions about climate change, falling short of the ultimate goal of achieving widespread climate literacy. Especially troubling was the sparse attention to the principles addressing the human connection to the climate - principles number 6 and 7. If climate literate citizens are to make "wise personal and policy decisions" (USGCRP, 2009), these two principles especially are vital. This research, therefore, has been valuable for identifying current shortcomings in state standards.

Astrobiology Workshop: Leadership in Astrobiology

NASA Technical Reports Server (NTRS)

DeVincenzi, D. (Editor); Briggs, G.; Cohen, M.; Cuzzi, J.; DesMarais, D.; Harper, L.; Morrison, D.; Pohorille, A.

1996-01-01

Astrobiology is defined in the 1996 NASA Strategic Plan as 'The study of the living universe.' At NASA's Ames Research Center, this endeavor encompasses the use of space to understand life's origin, evolution, and destiny in the universe. Life's origin refers to understanding the origin of life in the context of the origin and diversity of planetary systems. Life's evolution refers to understanding how living systems have adapted to Earth's changing environment, to the all-pervasive force of gravity, and how they may adapt to environments beyond Earth. Life's destiny refers to making long-term human presence in space a reality, and laying the foundation for understanding and managing changes in Earth's environment. The first Astrobiology Workshop brought together a diverse group of researchers to discuss the following general questions: Where and how are other habitable worlds formed? How does life originate? How have the Earth and its biosphere influenced each other over time? Can terrestrial life be sustained beyond our planet? How can we expand the human presence to Mars? The objectives of the Workshop included: discussing the scope of astrobiology, strengthening existing efforts for the study of life in the universe, identifying new cross-disciplinary programs with the greatest potential for scientific return, and suggesting steps needed to bring this program to reality. Ames has been assigned the lead role for astrobiology by NASA in recognition of its strong history of leadership in multidisciplinary research in the space, Earth, and life sciences and its pioneering work in studies of the living universe. This initial science workshop was established to lay the foundation for what is to become a national effort in astrobiology, with anticipated participation by the university community, other NASA centers, and other agencies. This workshop (the first meeting of its kind ever held) involved life, Earth, and space scientists in a truly interdisciplinary sharing of ideas related to life in the universe, and by all accounts was a resounding success.

Metaheuristic Optimization and its Applications in Earth Sciences

NASA Astrophysics Data System (ADS)

Yang, Xin-She

2010-05-01

A common but challenging task in modelling geophysical and geological processes is to handle massive data and to minimize certain objectives. This can essentially be considered as an optimization problem, and thus many new efficient metaheuristic optimization algorithms can be used. In this paper, we will introduce some modern metaheuristic optimization algorithms such as genetic algorithms, harmony search, firefly algorithm, particle swarm optimization and simulated annealing. We will also discuss how these algorithms can be applied to various applications in earth sciences, including nonlinear least-squares, support vector machine, Kriging, inverse finite element analysis, and data-mining. We will present a few examples to show how different problems can be reformulated as optimization. Finally, we will make some recommendations for choosing various algorithms to suit various problems.

The Macroecology of Sustainability

The discipline of sustainability science has emerged in response to concerns of natural and social scientists, policymakers, and lay people about whether the Earth can continue to support human population growth and economic prosperity. Yet, sustainability science has developed largely independently from and with little reference to key ecological principles that govern life on Earth. A macroecological perspective highlights three principles that should be integral to sustainability science: 1) physical conservation laws govern the flows of energy and materials between human systems and the environment, 2) smaller systems are connected by these flows to larger systems in which they are embedded, and 3) global constraints ultimately limit flows at smaller scales. Over the past few decades, decreasing per capita rates of consumption of petroleum, phosphate, agricultural land, fresh water, fish, and wood indicate that the growing human population has surpassed the capacity of the Earth to supply enough of these essential resources to sustain even the current population and level of socioeconomic development.

Using Earth System Science as Basis for Sustainability Education in an Undergraduate Environmental Science Program

NASA Astrophysics Data System (ADS)

Sinton, C. W.

2012-12-01

Undergraduate programs in Environmental Science (ES) have progressively grown over the past decades. One of the many challenges of providing an effective curriculum is deciding what content and which skills are included in such a wide ranging field. Certainly geoscience needs to be included as part of the content but how is this best executed? More precisely, what should ES majors know about how the earth, oceans, and atmosphere work? One possible approach is to include existing undergraduate geology or atmospheric science courses as part of the required core, but this has potential pitfalls. For example, courses may be geared toward general education requirements or may be designed more for geology majors. A better solution is to offer a course or set of courses that are specifically tailored for ES majors. I propose that Earth System Science (ESS) is an excellent approach as it incorporates the earth as a whole system and can be taught within the context of environmental sustainability. My approach to ESS is to focus on the movement/cycles of matter (e.g., carbon, calcium, nitrogen) and energy. By referring back to this focus throughout the semester, students are provided with a structure to begin to make sense of a complex problem. In support of this, lab exercises provide practice in collecting and analyzing data using a variety resources.

Estimates indicate that the world's information will grow by 800% in the next five years. In any given field, a single researcher or a team of researchers cannot keep up with this rate of knowledge expansion without the help of cognitive systems. Cognitive computing, defined as the use of information technology to augment human cognition, can help tackle large systemic problems. Knowledge graphs, one of the foundational components of cognitive systems, link key entities in a specific domain with other entities via relationships. Researchers could mine these graphs to make probabilistic recommendations and to infer new knowledge. At this point, however, there is a dearth of tools to generate scalable Knowledge graphs using existing corpus of scientific literature for Earth science research. Our project is currently developing an end-to-end automated methodology for incrementally constructing Knowledge graphs for Earth Science. Semantic Entity Recognition (SER) is one of the key steps in this methodology. SER for Earth Science uses external resources (including metadata catalogs and controlled vocabulary) as references to guide entity extraction and recognition (i.e., labeling) from unstructured text, in order to build a large training set to seed the subsequent auto-learning component in our algorithm. Results from several SER experiments will be presented as well as lessons learned.

Earth Observations from Space: The First 50 Years of Scientific Achievements

NASA Technical Reports Server (NTRS)

2008-01-01

Observing Earth from space over the past 50 years has fundamentally transformed the way people view our home planet. The image of the "blue marble" is taken for granted now, but it was revolutionary when taken in 1972 by the crew on Apollo 17. Since then the capability to look at Earth from space has grown increasingly sophisticated and has evolved from simple photographs to quantitative measurements of Earth properties such as temperature, concentrations of atmospheric trace gases, and the exact elevation of land and ocean. Imaging Earth from space has resulted in major scientific accomplishments; these observations have led to new discoveries, transformed the Earth sciences, opened new avenues of research, and provided important societal benefits by improving the predictability of Earth system processes. This report highlights the scientific achievements made possible by the first five decades of Earth satellite observations by space-faring nations. It follows on a recent report from the National Research Council (NRC) entitled Earth Science and Applications from Space: National Imperatives for the Next Decade and Beyond, also referred to as the "decadal survey." Recognizing the increasing need for space observations, the decadal survey identifies future directions and priorities for Earth observations from space. This companion report was requested by the National Aeronautics and Space Administration (NASA) to highlight, through selected examples, important past contributions of Earth observations from space to our current understanding of the planet.

Digital Earth reloaded - Beyond the next generation

NASA Astrophysics Data System (ADS)

Ehlers, M.; Woodgate, P.; Annoni, A.; Schade, S.

2014-02-01

Digital replicas (or 'mirror worlds') of complex entities and systems are now routine in many fields such as aerospace engineering; archaeology; medicine; or even fashion design. The Digital Earth (DE) concept as a digital replica of the entire planet occurs in Al Gore's 1992 book Earth in the Balance and was popularized in his speech at the California Science Center in January 1998. It played a pivotal role in stimulating the development of a first generation of virtual globes, typified by Google Earth that achieved many elements of this vision. Almost 15 years after Al Gore's speech, the concept of DE needs to be re-evaluated in the light of the many scientific and technical developments in the fields of information technology, data infrastructures, citizen?s participation, and earth observation that have taken place since. This paper intends to look beyond the next generation predominantly based on the developments of fields outside the spatial sciences, where concepts, software, and hardware with strong relationships to DE are being developed without referring to this term. It also presents a number of guiding criteria for future DE developments.

An Engineering Design Reference Mission for a Future Large-Aperture UVOIR Space Observatory

Thronson, Harley A.; Bolcar, Matthew R.; Clampin, Mark; Crooke, Julie A.; Redding, David; Rioux, Norman; Stahl, H. Philip

2016-01-01

From the 2010 NRC Decadal Survey and the NASA Thirty-Year Roadmap, Enduring Quests, Daring Visions, to the recent AURA report, From Cosmic Birth to Living Earths, multiple community assessments have recommended development of a large-aperture UVOIR space observatory capable of achieving a broad range of compelling scientific goals. Of these priority science goals, the most technically challenging is the search for spectroscopic biomarkers in the atmospheres of exoplanets in the solar neighborhood. Here we present an engineering design reference mission (EDRM) for the Advanced Technology Large-Aperture Space Telescope (ATLAST), which was conceived from the start as capable of breakthrough science paired with an emphasis on cost control and cost effectiveness. An EDRM allows the engineering design trade space to be explored in depth to determine what are the most demanding requirements and where there are opportunities for margin against requirements. Our joint NASA GSFC/JPL/MSFC/STScI study team has used community-provided science goals to derive mission needs, requirements, and candidate mission architectures for a future large-aperture, non-cryogenic UVOIR space observatory. The ATLAST observatory is designed to operate at a Sun-Earth L2 orbit, which provides a stable thermal environment and excellent field of regard. Our reference designs have emphasized a serviceable 36-segment 9.2 m aperture telescope that stows within a five-meter diameter launch vehicle fairing. As part of our cost-management effort, this particular reference mission builds upon the engineering design for JWST. Moreover, it is scalable to a variety of launch vehicle fairings. Performance needs developed under the study are traceable to a variety of additional reference designs, including options for a monolithic primary mirror.

EVER-EST: European Virtual Environment for Research in Earth Science Themes

NASA Astrophysics Data System (ADS)

Glaves, H.; Albani, M.

2016-12-01

EVER-EST is an EC Horizon 2020 project having the goal to develop a Virtual Research Environment (VRE) providing a state-of-the-art solution to allow Earth Scientists to preserve their work and publications for reference and future reuse, and to share with others. The availability of such a solution, based on an innovative concept and state of art technology infrastructure, will considerably enhance the quality of how Earth Scientists work together within their own institution and also across other organizations, regions and countries. The concept of Research Objects (ROs), used in the Earth Sciences for the first time, will form the backbone of the EVER-EST VRE infrastructure. ROs will enhance the ability to preserve, re-use and share entire or individual parts of scientific workflows and all the resources related to a specific scientific investigation. These ROs will also potentially be used as part of the scholarly publication process. EVER-EST is building on technologies developed during almost 15 years of research on Earth Science data management infrastructures. The EVER-EST VRE Service Oriented Architecture is being meticulously designed to accommodate at best the requirements of a wide range of Earth Science communities and use cases: focus is put on common requirements and on minimising the level of complexity in the EVER-EST VRE to ensure future sustainability within the user communities beyond the end of the project. The EVER-EST VRE will be validated through its customisation and deployment by four Virtual Research Communities (VRCs) from different Earth Science disciplines and will support enhanced interaction between data providers and scientists in the Earth Science domain. User community will range from bio-marine researchers (Sea Monitoring use case), to common foreign and security policy institutions and stakeholders (Land Monitoring for Security use case), natural hazards forecasting systems (Natural Hazards use case), and disaster and risk management teams (Supersites use case). The EVER-EST project will coordinate and collaborate with other relevant initiatives worldwide mainly through the Research Data Alliance (RDA) Virtual Research Environments interest group (VRE-IG).

The magnetometer experiment onboard Juno is equipped with four non-magnetic star tracker camera heads, two of which reside on each of the magnetometer sensor optical benches. These are located 10 and 12 m from the spacecraft body at the end of one of the three solar panel wings. The star tracker, collectively referred to as the Advanced Stellar Compass (ASC), provides high accuracy attitude information for the magnetometer sensors throughout science operations. The star tracker camera heads are pointed +/- 13 deg off the spin vector, in the anti-sun direction, imaging a 13 x 20 deg field of view every ¼ second as Juno rotates at 1 or 2 rpm. The ASC is a fully autonomous star tracker, producing a time series of attitude quaternions for each camera head, utilizing a suite of internal support functions. These include imaging capabilities, autonomous object tracking, automatic dark-sky monitoring, and related capabilities; these internal functions may be accessed via telecommand. During Juno's cruise phase, this capability can be tapped to provide unique science and engineering data available along the Juno trajectory. We present a few examples of the JUNO ASC opportunity science here. As the Juno spacecraft approached the Earth-Moon system for the close encounter with the Earth on October 9, 2013, one of the ASC camera heads obtained imagery of the Earth-Moon system while the other three remained in full science (attitude determination) operation. This enabled the first movie of the Earth and Moon obtained by a spacecraft flying past the Earth in gravity assist. We also use the many artificial satellites in orbit about the Earth as calibration targets for the autonomous asteroid detection system inherent to the ASC autonomous star tracker. We shall also profile the zodiacal dust disk, using the interstellar image data, and present the outlook for small asteroid body detection and distribution being performed during Juno's passage from Earth flyby to Jovian orbit insertion.

Allison, M. Lee; Gundersen, Linda C.; Richard, Stephen M.; Keller, G. Randy; Baru, Chaitanya

2011-01-01

Advanced information technology infrastructure is increasingly being employed in the Earth sciences to provide researchers with efficient access to massive central databases and to integrate diversely formatted information from a variety of sources. These geoinformatics initiatives enable manipulation, modeling and visualization of data in a consistent way, and are helping to develop integrated Earth models at various scales, and from the near surface to the deep interior. This book uses a series of case studies to demonstrate computer and database use across the geosciences. Chapters are thematically grouped into sections that cover data collection and management; modeling and community computational codes; visualization and data representation; knowledge management and data integration; and web services and scientific workflows. Geoinformatics is a fascinating and accessible introduction to this emerging field for readers across the solid Earth sciences and an invaluable reference for researchers interested in initiating new cyberinfrastructure projects of their own.

An Educator's Resource Guide to Earthquakes and Seismology

NASA Astrophysics Data System (ADS)

Johnson, J.; Lahr, J. C.; Butler, R.

2007-12-01

When a major seismic event occurs, millions of people around the world want to understand what happened. This presents a challenge to many classroom science teachers not well versed in Earth science. In response to this challenge, teachers may try surfing the Internet to ferret out the basics. Following popular links can be time consuming and frustrating, so that the best use is not made of this "teachable moment." For isolated rural teachers with limited Internet access, surfing for information may not be a viable option. A partnership between EarthScope/USArray, High Lava Plains Project (Carnegie Institution/Arizona State University, Portland State University, and isolated K-12 schools in rural SE Oregon generated requests for a basic "Teachers Guide to Earthquakes." To bridge the inequalities in information access and varied science background, EarthScope/USArray sponsored the development of a CD that would be a noncommercial repository of Earth and earthquake-related science resources. A subsequent partnership between the University of Portland, IRIS, the USGS, and Portland-area school teachers defined the needs and provided the focus to organize sample video lectures, PowerPoint presentations, new Earth-process animations, and activities on a such a large range of topics that soon the capacity of a DVD was required. Information was culled from oft-referenced sources, always seeking clear descriptions of processes, basic classroom-tested instructional activities, and effective Web sites. Our format uses a master interactive PDF "book" that covers the basics, from the interior of the Earth and plate tectonics to seismic waves, with links to reference folders containing activities, new animations, and video demos. This work-in-progress DVD was initially aimed at middle school Earth-science curriculum, but has application throughout K-16. Strong support has come from university professors wanting an organized collection of seismology resources. The DVD shows how the study of seismology advances our understanding of the Earth and how students and teachers can access seismic data from USArray stations to promote discussion about earthquakes worldwide. Instructions on how to view USArray data, as well as activities using data from EarthScope's vast array of monitoring equipment, are being generated and incorporated as they prove effective.

The ISECG Science White Paper - A Scientific Perspective on the Global Exploration Roadmap

NASA Astrophysics Data System (ADS)

Bussey, David B.; Worms, Jean-Claude; Spiero, Francois; Schlutz, Juergen; Ehrenfreund, Pascale

2016-07-01

Future space exploration goals call for sending humans and robots beyond low Earth orbit and establishing sustained access to destinations such as the Moon, asteroids and Mars. Space agencies participating in the International Space Exploration Coordination Group (ISECG) are discussing an international approach for achieving these goals, documented in ISECG's Global Exploration Roadmap (GER). The GER reference scenario reflects a step-wise evolution of critical capabilities from ISS to missions in the lunar vicinity in preparation for the journey of humans to Mars. As an element of this continued road mapping effort, the ISECG agencies are therefore soliciting input and coordinated discussion with the scientific community to better articulate and promote the scientific opportunities of the proposed mission themes. An improved understanding of the scientific drivers and the requirements to address priority science questions associated with the exploration destinations (Moon, Near Earth Asteroids, Mars and its moons) as well as the preparatory activities in cis-lunar space is beneficial to optimize the partnership of robotic assets and human presence beyond low Earth orbit. The interaction has resulted in the development of a Science White Paper to: • Identify and highlight the scientific opportunities in early exploration missions as the GER reference architecture matures, • Communicate overarching science themes and their relevance in the GER destinations, • Ensure international science communities' perspectives inform the future evolution of mission concepts considered in the GER The paper aims to capture the opportunities offered by the missions in the GER for a broad range of scientific disciplines. These include planetary and space sciences, astrobiology, life sciences, physical sciences, astronomy and Earth science. The paper is structured around grand science themes that draw together and connect research in the various disciplines, and it will focus on opportunities created by the near-term mission themes in the GER centred around 1) extended duration crew missions to an exploration habitat in cis-lunar space, 2) crew mission(s) to an asteroid, and 3) crew missions to the lunar surface. The preparation of that Science White Paper has been coordinated and led by an external Science Advisory Group composed of scientists form a variety of nations. The first draft of this White Paper has been discussed on the occasion of a COSPAR-ISECG-ESF workshop organised in Paris on 10-11 February 2016. The recommendations developed at the workshop provide further input that is incorporated in the final version of the ISECG Science White Paper, expected to be published in the fall of 2016. The authors aim to present the rationale and contents of this White Paper on the occasion of the COSPAR Assembly.

New Data Services for Polar Investigators from Integrated Earth Data Applications (IEDA)

Accessibility and preservation of data is needed to support multi-disciplinary research in the key environmentally sensitive Polar Regions. IEDA (Integrated Earth Data Applications) is a community-based data facility funded by the US National Science Foundation (NSF) to support, sustain, and advance the geosciences by providing data services for observational solid earth data from the Ocean, Earth, and Polar Sciences. IEDA tools and services relevant to the Polar Research Community include the Antarctic and Southern Ocean Data System (ASODS), the U.S. Antarctic Program Data Coordination Center (USAP-DCC), GeoMapApp, as well as a number of services for sample-based data (SESAR and EarthChem). In addition to existing tools, which assist Polar investigators in archiving their data, and creating DIF records for global searches in AMD, IEDA recently added several new tools and services that will provide further support for investigators with the data life cycle process. These include a data management plan (http://www.iedadata.org/compliance/plan) and data compliance reporting tool (http://www.iedadata.org/compliance/report) that will help investigators comply with the requirements of funding agencies such as the National Science Foundation (NSF). Data, especially from challenging Polar Regions, are likely to be used by other scientists for future studies. Therefore, data acknowledgment is an important concern of many investigators. To encourage data acknowledgments by data users, we link references of publications (when known) to datasets and cruises registered within the ASODS system as part of our data curation services (http://www.marine-geo.org/portals/antarctic/references.php). In addition, IEDA offers a data publication service to register scientific data with DOI's, making data sets citable as publications with attribution to investigators as authors. IEDA is a publication agent of the DataCite consortium. Offering such services provides additional incentives for making data available through data centers. Such tools and services are important building blocks of a coherent and comprehensive (cyber) data support structure for Polar investigators.

Raising awareness for research on earth walls, and earth scientific aspects

2013-04-01

A conference to raise awareness In the Netherlands, little research on earth walls has been done. To improve attention for earth walls, a number of organisations, including Geoheritage NL, organized a conference at the RCE, the Cultural Heritage Agency of the Netherlands. The conference* presented a state-of-the-art of research done. The book with the presentations, and extra case studies added, was published in December 2012. The book concludes with a research action list, including earth science research, and can be downloaded freely from the internet. It has English summaries. The earth science aspects Historical earth walls do not only add cultural value to a landscape, but also geodiversity value. Apart from geomorphological aspects, the walls contain information about past land- and climate conditions: - They cover up a former topography, a past landscape. A relevant source of scientific information where lands are levelled, as is the case in many parts of The Netherlands; - The soil formation under the earth wall is a reference soil. The soil formation in the top of the wall gives insight in the rate of soil formation in relationship with the age and parent material of the wall; - The soil profiles of different age have ecological significance. Older walls with a more pronounced soil formation often hold forest flora that has disappeared from the surrounding environment, such as historical bush or tree species, autogenetic DNA material or a specific soil fauna; - The materials in the earth walls tell about the process of wall-building. Paleosols and sedimentary structures in the earth walls, in the gullies and colluvial fans along the walls contain information about past land management and climate. - The eroded appearance of the earth walls is part of their history, and contain information about past management and land conditions, has ecological relevance, for example for insects, and is often visually more interesting. Insight in the rates of erosion are important for earth wall maintenance. A reconnaissance study of earth science aspects of earth walls in Ede The poster further presents a reconnaissance study in the municipality Ede describing differences in morphology, geology and soil profile development. E.g. totally black plaggen A-like horizons occur over 1 m thick, as well as differences in brown B-horizons from 0 cm, 2-3 cm to 15-20 cm. Inferred from cultural data, 2-3 cm B-horizons have an age of about two - three hundred years. Reference Henk Baas, Bert Groenwoudt, Pim Jungerius, Hans Renes (eds.), 2012.

Precession, Nutation and Wobble of the Earth

NASA Astrophysics Data System (ADS)

Dehant, V.; Mathews, P. M.

2015-04-01

Covering both astronomical and geophysical perspectives, this book describes changes in the Earth's orientation, specifically precession and nutation, and how they are observed and computed in terms of tidal forcing and models of the Earth's interior. Following an introduction to key concepts and elementary geodetic theory, the book describes how precise measurements of the Earth's orientation are made using observations of extra-galactic radio-sources by Very Long Baseline Interferometry techniques. It demonstrates how models are used to accurately pinpoint the location and orientation of the Earth with reference to the stars and how to determine variations in its rotation speed. A theoretical framework is also presented that describes the role played by the structure and properties of the Earth's deep interior. Incorporating suggestions for future developments in nutation theory for the next generation models, this book is ideal for advanced-level students and researche! rs in solid Earth geophysics, planetary science and astronomy.

[Geognosy versus Geology: National Modes of Thought and Cultural Practices Concerning Space and Time in Competition].

PubMed

Klemun, Marianne

2015-09-01

Natural science investigators at the end of the eighteenth century made use of conflicting labels to position their respective preferred fields of activity in the Earth sciences. This mania for labelling marked their break with natural science and the umbrella term 'mineralogy'. In this conflict situation of specialist classifications and explanations, two terms in particular were established: geognosy and geology, which covered the very promising project of research in the areas of the 'origin of the Earth' and the 'formation of the Earth'. These and the associated research goals were subsequently accorded a dazzling career. Proceeding from the conceptual core-meaning in the formation of terms und its semantic spectrum and conceptual shifts in a time of change, my study will look at the identity and heterogeneity functions of geology and geognosy. For whereas in French and English speaking countries the term geology came to be used exclusively (geology, géologie), this was avoided in German, particularly because the term geognosy was preferred. These national differences may be explained with reference to the different cultural and national styles of science: for example the social embedding of geology in the culture of the English gentleman or the French museum culture, and the close connection of 'German' geognosy to mining. A further starting point in the analysis of the double use of both geology and geognosy in German speaking countries until 1840 is provided by the different references to temporalization and spatialization of the two terms. And we should also include the practical implications and the epistemic requirements that were bound up with the defence of geognosy in the German speaking world.

Earth Science Datacasting v2.0

Bingham, Andrew W.; Deen, Robert G.; Hussey, Kevin J.; Stough, Timothy M.; McCleese, Sean W.; Toole, Nicholas T.

2012-01-01

The Datacasting software, which consists of a server and a client, has been developed as part of the Earth Science (ES) Datacasting project. The goal of ES Datacasting is to provide scientists the ability to automatically and continuously download Earth science data that meets a precise, predefined need, and then to instantaneously visualize it on a local computer. This is achieved by applying the concept of podcasting to deliver science data over the Internet using RSS (Really Simple Syndication) XML feeds. By extending the RSS specification, scientists can filter a feed and only download the files that are required for a particular application (for example, only files that contain information about a particular event, such as a hurricane or flood). The extension also provides the ability for the client to understand the format of the data and visualize the information locally. The server part enables a data provider to create and serve basic Datacasting (RSS-based) feeds. The user can subscribe to any number of feeds, view the information related to each item contained within a feed (including browse pre-made images), manually download files associated with items, and place these files in a local store. The client-server architecture enables users to: a) Subscribe and interpret multiple Datacasting feeds (same look and feel as a typical mail client), b) Maintain a list of all items within each feed, c) Enable filtering on the lists based on different metadata attributes contained within the feed (list will reference only data files of interest), d) Visualize the reference data and associated metadata, e) Download files referenced within the list, and f) Automatically download files as new items become available.

Towards a Refined Realisation of the Terrestrial Reference System

Global reference frames provide the framework for scientific investigations of the Earth's system (e.g. plate tectonics, sea level change, seasonal and secular loading signals, atmosphere dynamics, Earth orientation excitation), as well as for many practical applications (e.g. surveying and navigation). Today, space geodetic techniques allow to determine geodetic parameters (e.g. station positions, Earth rotation) with a precision of a few millimeters (or even better). However, this high accuracy is not reflected by current realisations of the terrestrial reference system. To fully exploit the potential of the space geodetic observations for investigations of various global and regional, short-term, seasonal and secular phenomena of the Earth's system, the reference frame must be realised with the highest accuracy, spatial and temporal consistency and stability over decades. Furthermore, future progress in Earth sciences will fundamentally depend on understanding the Earth as a system, into which the three areas of geodetic research (geometry/deformation, Earth rotation, gravity) are to be integrated. The presentation focusses on various aspects that must be considered for a refined realisation of the terrestrial reference system, such as the development of suitable methods for the combination of the contributing space geodetic observations, the realisation of the TRF datum and the parameterisation of site motions. For this purpose we investigated time series of station positions and datum parameters obtained from VLBI, SLR, GPS and DORIS solutions, and compared the results at co-location sites and with other studies. Furthermore, we present results obtained from a TRS realisation based on epoch (weekly/daily) normal equations with station positions and daily Earth Orientation Parameters (EOP) using five years (1999-2004) of VLBI, SLR, GPS and DORIS data. This refined approach has major advantages compared to past TRF realisations based on multi-year solutions with station positions at a given epoch and constant velocities, as for instance non-linear effects of site positions and datum parameters can be considered, and consistency between TRF and EOPs can be achieved. First results of this new approach are promising.

Evaluating the Potential of NASA's Earth Science Research Results for Improving Future Operational Systems

NASA's Earth Science Theme is charged with implementing NASA Strategic Goal 3A to "study Earth from space to advance scientific understanding and meet societal needs." In the course of meeting this objective, NASA produces research results, such as scientific observatories, research models, advanced sensor and space system technology, data active archives and interoperability technology, high performance computing systems, and knowledge products. These research results have the potential to serve society beyond their intended purpose of answering pressing Earth system science questions. NASA's Applied Sciences Program systematically evaluates the potential of the portfolio of research results to serve society by conducting projects in partnership with regional/national scale operational partners with the statutory responsibility to inform decision makers. These projects address NASA's National Applications and the societal benefit areas under the IEOS and GEOSS. Prototyping methods are used in two ways in NASA's Applied Sciences Program. The first is part of the National Applications program element, referred to as Integrated Systems Solutions (ISS) projects. The approach for these projects is to use high fidelity prototypes to benchmark the assimilation of NASA research results into our partners' decision support systems. The outcome from ISS projects is a prototype system that has been rigorously tested with the partner to understand the scientific uncertainty and improved value of their modified system. In many cases, these completed prototypes are adopted or adapted for use by the operational partners. The second falls under the Crosscutting Solutions program element, referred to as Rapid Prototyping (RP) experiments. The approach for RP experiments is to use low fidelity prototypes that are low cost and quickly produced to evaluate the potential of the breadth of NASA research results to serve society. The outcome from the set of RP experiments is an evaluation of many and varied NASA research results for their potential to be candidates for further development as an ISS project. The intention is to seed the community with many creative ideas for projects that use "un-applied" NASA research results to serve society, such as simulations of future missions.

In this project we aim to pave a novel path to create a sustainable building block toward Earth science big data analytics and knowledge sharing. Closely studying how Earth scientists conduct data analytics research in their daily work, we have developed a provenance model to record their activities, and to develop a technology to automatically generate workflows for scientists from the provenance. On top of it, we have built the prototype of a data-centric provenance repository, and establish a PDSW (People, Data, Service, Workflow) knowledge network to support workflow recommendation. To ensure the scalability and performance of the expected recommendation system, we have leveraged the Apache OODT system technology. The community-approved, metrics-based performance evaluation web-service will allow a user to select a metric from the list of several community-approved metrics and to evaluate model performance using the metric as well as the reference dataset. This service will facilitate the use of reference datasets that are generated in support of the model-data intercomparison projects such as Obs4MIPs and Ana4MIPs. The data-centric repository infrastructure will allow us to catch richer provenance to further facilitate knowledge sharing and scientific collaboration in the Earth science community. This project is part of Apache incubator CMDA project.

Geoscience laser altimeter system-stellar reference system

Millar, Pamela S.; Sirota, J. Marcos

1998-01-01

GLAS is an EOS space-based laser altimeter being developed to profile the height of the Earth's ice sheets with ~15 cm single shot accuracy from space under NASA's Mission to Planet Earth (MTPE). The primary science goal of GLAS is to determine if the ice sheets are increasing or diminishing for climate change modeling. This is achieved by measuring the ice sheet heights over Greenland and Antarctica to 1.5 cm/yr over 100 km×100 km areas by crossover analysis (Zwally 1994). This measurement performance requires the instrument to determine the pointing of the laser beam to ~5 urad (1 arcsecond), 1-sigma, with respect to the inertial reference frame. The GLAS design incorporates a stellar reference system (SRS) to relate the laser beam pointing angle to the star field with this accuracy. This is the first time a spaceborne laser altimeter is measuring pointing to such high accuracy. The design for the stellar reference system combines an attitude determination system (ADS) with a laser reference system (LRS) to meet this requirement. The SRS approach and expected performance are described in this paper.

Solar and Space Physics: A Science for a Technological Society

2013-01-01

From the interior of the Sun, to the upper atmosphere and near-space environment of Earth, and outward to a region far beyond Pluto where the Sun's influence wanes, advances during the past decade in space physics and solar physics the disciplines NASA refers to as heliophysics have yielded spectacular insights into the phenomena that affect our home in space. This report, from the National Research Council's (NRC's) Committee for a Decadal Strategy in Solar and Space Physics, is the second NRC decadal survey in heliophysics. Building on the research accomplishments realized over the past decade, the report presents a program of basic and applied research for the period 2013-2022 that will improve scientific understanding of the mechanisms that drive the Sun's activity and the fundamental physical processes underlying near-Earth plasma dynamics, determine the physical interactions of Earth's atmospheric layers in the context of the connected Sun-Earth system, and enhance greatly the capability to provide realistic and specific forecasts of Earth's space environment that will better serve the needs of society. Although the recommended program is directed primarily to NASA (Science Mission Directorate -- Heliophysics Division) and the National Science Foundation (NSF) (Directorate for Geosciences -- Atmospheric and Geospace Sciences) for action, the report also recommends actions by other federal agencies, especially the National Oceanic and Atmospheric Administration (NOAA) those parts of NOAA charged with the day-to-day (operational) forecast of space weather. In addition to the recommendations included in this summary, related recommendations are presented in the main text of the report.

The Contribution of GGOS to Understanding Dynamic Earth Processes

NASA Astrophysics Data System (ADS)

Gross, Richard

2017-04-01

Geodesy is the science of the Earth's shape, size, gravity and rotation, including their evolution in time. Geodetic observations play a major role in the solid Earth sciences because they are fundamental for the understanding and modeling of Earth system processes. Changes in the Earth's shape, its gravitational field, and its rotation are caused by external forces acting on the Earth system and internal processes involving mass transfer and exchange of angular and linear momentum. Thus, variations in these geodetic quantities of the Earth reflect and constrain mechanical and thermo-dynamic processes in the Earth system. Mitigating the impact on human life and property of natural hazards such as earthquakes, volcanic eruptions, debris flows, landslides, land subsidence, sea level change, tsunamis, floods, storm surges, hurricanes and extreme weather is an important scientific task to which geodetic observations make fundamental contributions. Geodetic observations can be used to monitor the pre-eruptive deformation of volcanoes and the pre-seismic deformation of earthquake fault zones, aiding in the issuance of volcanic eruption and earthquake warnings. They can also be used to rapidly estimate earthquake fault motion, aiding in the modeling of tsunami genesis and the issuance of tsunami warnings. Geodetic observations are also used in other areas of the Earth sciences, not just the solid Earth sciences. For example, geodesy contributes to atmospheric science by supporting both observation and prediction of the weather by geo-referencing meteorological observing data and by globally tracking change in stratospheric mass and lower tropospheric water vapor fields. Geodetic measurements of refraction profiles derived from satellite occultation data are routinely assimilated into numerical weather prediction models. Geodesy contributes to hydrologic studies by providing a unique global reference system for measurements of: sub-seasonal, seasonal and secular movements of continental and basin-scale water masses; loading and unloading of the land surface due to seasonal changes of groundwater; measurement of water level of major lakes and rivers by satellite altimetry; and improved digital terrain models as basis for flux modeling of surface water and flood modeling. Geodesy is crucial for cryospheric studies because of its ability to measure the motions of ice masses and changes in their volumes. Ice sheets, glaciers, and sea ice are intricately linked to the Earth's climate system. They store a record of past climate; they strongly affect surface energy budget, global water cycle, and sea-level change; and they are sensitive indicators of climate change. Geodesy is at the heart of all present-day ocean studies. Geodetic observations uniquely produce accurate, quantitative, and integrated observations of gravity, ocean circulation, sea surface height, ocean bottom pressure, and mass exchanges among the ocean, cryosphere, and land. Geodetic observations have made fundamental contributions to monitoring and understanding physical ocean processes. In particular, geodesy is the basic technique used to determine an accurate geoid model, allowing for the determination of absolute surface geostrophic currents, which are necessary to quantify heat transport of the ocean. Geodesy also provides the absolute reference for tide gauge measurements, allowing those measurements to be merged with satellite altimetric measurements to provide a coherent worldwide monitoring system for sea level change. In this presentation, selected examples of the contribution of geodetic observations to understanding the dynamic Earth system will be presented.

Petascale Kinetic Simulations in Space Sciences: New Simulations and Data Discovery Techniques and Physics Results

NASA Astrophysics Data System (ADS)

Karimabadi, Homa

2012-03-01

Recent advances in simulation technology and hardware are enabling breakthrough science where many longstanding problems can now be addressed for the first time. In this talk, we focus on kinetic simulations of the Earth's magnetosphere and magnetic reconnection process which is the key mechanism that breaks the protective shield of the Earth's dipole field, allowing the solar wind to enter the Earth's magnetosphere. This leads to the so-called space weather where storms on the Sun can affect space-borne and ground-based technological systems on Earth. The talk will consist of three parts: (a) overview of a new multi-scale simulation technique where each computational grid is updated based on its own unique timestep, (b) Presentation of a new approach to data analysis that we refer to as Physics Mining which entails combining data mining and computer vision algorithms with scientific visualization to extract physics from the resulting massive data sets. (c) Presentation of several recent discoveries in studies of space plasmas including the role of vortex formation and resulting turbulence in magnetized plasmas.

2016-01-01

The anticipated upcoming large mission study concepts for the direct imaging of exo-earths present an exciting opportunity for exoplanet discovery and characterization. While these telescope concepts would also be capable of conducting a broad range of astrophysical investigations, the most difficult technology challenges are driven by the requirements for imaging exo-earths. The exoplanet science yield for these mission concepts will drive design trades and mission concept comparisons.To assist in these trade studies, the Exoplanet Exploration Program Office (ExEP) is developing a yield estimation tool that emphasizes transparency and consistent comparison of various design concepts. The tool will provide a parametric estimate of science yield of various mission concepts using contrast curves from physics-based model codes and Monte Carlo simulations of design reference missions using realistic constraints, such as solar avoidance angles, the observatory orbit, propulsion limitations of star shades, the accessibility of candidate targets, local and background zodiacal light levels, and background confusion by stars and galaxies. The python tool utilizes Dmitry Savransky's EXOSIMS (Exoplanet Open-Source Imaging Mission Simulator) design reference mission simulator that is being developed for the WFIRST Preliminary Science program. ExEP is extending and validating the tool for future mission concepts under consideration for the upcoming 2020 decadal review. We present a validation plan and preliminary yield results for a point design.

Progress and Challenges in Developing Reference Data Layers for Human Population Distribution and Built Infrastructure

Chen, R. S.; Yetman, G.; de Sherbinin, A. M.

Understanding the interactions between environmental and human systems, and in particular supporting the applications of Earth science data and knowledge in place-based decision making, requires systematic assessment of the distribution and dynamics of human population and the built human infrastructure in conjunction with environmental variability and change. The NASA Socioeconomic Data and Applications Center (SEDAC) operated by the Center for International Earth Science Information Network (CIESIN) at Columbia University has had a long track record in developing reference data layers for human population and settlements and is expanding its efforts on topics such as intercity roads, reservoirs and dams, and energy infrastructure. SEDAC has set as a strategic priority the acquisition, development, and dissemination of data resources derived from remote sensing and socioeconomic data on urban land use change, including temporally and spatially disaggregated data on urban change and rates of change, the built infrastructure, and critical facilities. We report here on a range of past and ongoing activities, including the Global Human Settlements Layer effort led by the European Commission's Joint Research Centre (JRC), the Global Exposure Database for the Global Earthquake Model (GED4GEM) project, the Global Roads Open Access Data Working Group (gROADS) of the Committee on Data for Science and Technology (CODATA), and recent work with ImageCat, Inc. to improve estimates of the exposure and fragility of buildings, road and rail infrastructure, and other facilities with respect to selected natural hazards. New efforts such as the proposed Global Human Settlement indicators initiative of the Group on Earth Observations (GEO) could help fill critical gaps and link potential reference data layers with user needs. We highlight key sectors and themes that require further attention, and the many significant challenges that remain in developing comprehensive, high quality, up-to-date, and well maintained reference data layers on population and built infrastructure. The need for improved indicators of sustainable development in the context of the post-2015 development framework provides an opportunity to link data efforts directly with international development needs and investments.

Data Identifiers, Versioning, and Micro-citation

NASA Astrophysics Data System (ADS)

Parsons, M. A.; Duerr, R. E.

2012-12-01

Data citation, especially using Digital Object Identifiers (DOIs), is an increasingly accepted scientific practice. For example, the AGU Council asserts that data "publications" should "be credited and cited like the products of any other scientific activity," and Thomson Reuters has recently announced a data citation index built from DOIs assigned to data sets. Correspondingly, formal guidelines for how to cite a data set (using DOIs or similar identifiers/locators) have recently emerged, notably those from the international DataCite consortium, the UK Digital Curation Centre, and the US Federation of Earth Science Information Partners. These different data citation guidelines are largely congruent. They agree on the basic practice and elements of data citation, especially for relatively static, whole data collections. There is less agreement on some of the more subtle nuances of data citation. They define different methods for handling different data set versions, especially for the very dynamic, growing data sets that are common in Earth Sciences. They also differ in how people should cite specific, arbitrarily large elements, "passages," or subsets of a larger data collection, i.e., the precise data records actually used in a study. This detailed "micro-citation", and careful reference to exact versions of data are essential to ensure scientific reproducibility. Identifiers such as DOIs are necessary but not sufficient for the precise, detailed, references necessary. Careful practice must be coupled with the use of curated identifiers. In this paper we review the pros and cons of different approaches to versioning and micro-citation. We suggest a workable solution for most existing Earth science data and suggest a more rigorous path forward for the future.

Earth Science Data Analytics: Preparing for Extracting Knowledge from Information

NASA Technical Reports Server (NTRS)

Kempler, Steven; Barbieri, Lindsay

2016-01-01

Data analytics is the process of examining large amounts of data of a variety of types to uncover hidden patterns, unknown correlations and other useful information. Data analytics is a broad term that includes data analysis, as well as an understanding of the cognitive processes an analyst uses to understand problems and explore data in meaningful ways. Analytics also include data extraction, transformation, and reduction, utilizing specific tools, techniques, and methods. Turning to data science, definitions of data science sound very similar to those of data analytics (which leads to a lot of the confusion between the two). But the skills needed for both, co-analyzing large amounts of heterogeneous data, understanding and utilizing relevant tools and techniques, and subject matter expertise, although similar, serve different purposes. Data Analytics takes on a practitioners approach to applying expertise and skills to solve issues and gain subject knowledge. Data Science, is more theoretical (research in itself) in nature, providing strategic actionable insights and new innovative methodologies. Earth Science Data Analytics (ESDA) is the process of examining, preparing, reducing, and analyzing large amounts of spatial (multi-dimensional), temporal, or spectral data using a variety of data types to uncover patterns, correlations and other information, to better understand our Earth. The large variety of datasets (temporal spatial differences, data types, formats, etc.) invite the need for data analytics skills that understand the science domain, and data preparation, reduction, and analysis techniques, from a practitioners point of view. The application of these skills to ESDA is the focus of this presentation. The Earth Science Information Partners (ESIP) Federation Earth Science Data Analytics (ESDA) Cluster was created in recognition of the practical need to facilitate the co-analysis of large amounts of data and information for Earth science. Thus, from a to advance science point of view: On the continuum of ever evolving data management systems, we need to understand and develop ways that allow for the variety of data relationships to be examined, and information to be manipulated, such that knowledge can be enhanced, to facilitate science. Recognizing the importance and potential impacts of the unlimited ways to co-analyze heterogeneous datasets, now and especially in the future, one of the objectives of the ESDA cluster is to facilitate the preparation of individuals to understand and apply needed skills to Earth science data analytics. Pinpointing and communicating the needed skills and expertise is new, and not easy. Information technology is just beginning to provide the tools for advancing the analysis of heterogeneous datasets in a big way, thus, providing opportunity to discover unobvious scientific relationships, previously invisible to the science eye. And it is not easy It takes individuals, or teams of individuals, with just the right combination of skills to understand the data and develop the methods to glean knowledge out of data and information. In addition, whereas definitions of data science and big data are (more or less) available (summarized in Reference 5), Earth science data analytics is virtually ignored in the literature, (barring a few excellent sources).

EarthChem and SESAR: Data Resources and Interoperability for EarthScope Cyberinfrastructure

NASA Astrophysics Data System (ADS)

Lehnert, K. A.; Walker, D.; Block, K.; Vinay, S.; Ash, J.

2008-12-01

Data management within the EarthScope Cyberinfrastructure needs to pursue two goals in order to advance and maximize the broad scientific application and impact of the large volumes of observational data acquired by EarthScope facilities: (a) to provide access to all data acquired by EarthScope facilities, and to promote their use by broad audiences, and (b) to facilitate discovery of, access to, and integration of multi-disciplinary data sets that complement EarthScope data in support of EarthScope science. EarthChem and SESAR, the System for Earth Sample Registration, are two projects within the Geoinformatics for Geochemistry program that offer resources for EarthScope CI. EarthChem operates a data portal that currently provides access to >13 million analytical values for >600,000 samples, more than half of which are from North America, including data from the USGS and all data from the NAVDAT database, a web-accessible repository for age, chemical and isotopic data from Mesozoic and younger igneous rocks in western North America. The new EarthChem GEOCHRON database will house data collected in association with GeoEarthScope, storing and serving geochronological data submitted by participating facilities. The EarthChem Deep Lithosphere Dataset is a compilation of petrological data for mantle xenoliths, initiated in collaboration with GeoFrame to complement geophysical endeavors within EarthScope science. The EarthChem Geochemical Resource Library provides a home for geochemical and petrological data products and data sets. Parts of the digital data in EarthScope CI refer to physical samples such as drill cores, igneous rocks, or water and gas samples, collected, for example, by SAFOD or by EarthScope science projects and acquired through lab-based analysis. Management of sample-based data requires the use of global unique identifiers for samples, so that distributed data for individual samples generated in different labs and published in different papers can be unambiguously linked and integrated. SESAR operates a registry for Earth samples that assigns and administers the International GeoSample Numbers (IGSN) as a global unique identifier for samples. Registration of EarthScope samples with SESAR and use of the IGSN will ensure their unique identification in publications and data systems, thus facilitating interoperability among sample-based data relevant to EarthScope CI and globally. It will also make these samples visible to global audiences via the SESAR Global Sample Catalog.

EarthServer: Cross-Disciplinary Earth Science Through Data Cube Analytics

NASA Astrophysics Data System (ADS)

Baumann, P.; Rossi, A. P.

2016-12-01

The unprecedented increase of imagery, in-situ measurements, and simulation data produced by Earth (and Planetary) Science observations missions bears a rich, yet not leveraged potential for getting insights from integrating such diverse datasets and transform scientific questions into actual queries to data, formulated in a standardized way.The intercontinental EarthServer [1] initiative is demonstrating new directions for flexible, scalable Earth Science services based on innovative NoSQL technology. Researchers from Europe, the US and Australia have teamed up to rigorously implement the concept of the datacube. Such a datacube may have spatial and temporal dimensions (such as a satellite image time series) and may unite an unlimited number of scenes. Independently from whatever efficient data structuring a server network may perform internally, users (scientist, planners, decision makers) will always see just a few datacubes they can slice and dice.EarthServer has established client [2] and server technology for such spatio-temporal datacubes. The underlying scalable array engine, rasdaman [3,4], enables direct interaction, including 3-D visualization, common EO data processing, and general analytics. Services exclusively rely on the open OGC "Big Geo Data" standards suite, the Web Coverage Service (WCS). Conversely, EarthServer has shaped and advanced WCS based on the experience gained. The first phase of EarthServer has advanced scalable array database technology into 150+ TB services. Currently, Petabyte datacubes are being built for ad-hoc and cross-disciplinary querying, e.g. using climate, Earth observation and ocean data.We will present the EarthServer approach, its impact on OGC / ISO / INSPIRE standardization, and its platform technology, rasdaman.References: [1] Baumann, et al.

The consistency of the current conventional celestial and terrestrial reference frames and the conventional EOP series

NASA Astrophysics Data System (ADS)

Heinkelmann, R.; Belda-Palazon, S.; Ferrándiz, J.; Schuh, H.

2015-08-01

For applications in Earth sciences, navigation, and astronomy the celestial (ICRF) and terrestrial (ITRF) reference frames as well as the orientation among them, the Earth orientation parameters (EOP), have to be consistent at the level of 1 mm and 0.1 mm/yr (GGOS recommendations). We assess the effect of unmodelled geophysical signals in the regularized coordinates and the sensitivity with respect to different a priori EOP and celestial reference frames. The EOP are determined using the same VLBI data but with station coordinates fixed on different TRFs. The conclusion is that within the time span of data incorporated into ITRF2008 (Altamimi, et al., 2011) the ITRF2008 and the IERS 08 C04 are consistent. This consistency involves that non-linear station motion such as unmodelled geophysical signals partly affect the IERS 08 C04 EOP. There are small but not negligible inconsistencies between the conventional celestial reference frame, ICRF2 (Fey, et al., 2009), the ITRF2008 and the conventional EOP that are quantified by comparing VTRF2008 (Böckmann, et al., 2010) and ITRF2008.

Quantitative Modeling of Earth Surface Processes

NASA Astrophysics Data System (ADS)

Pelletier, Jon D.

This textbook describes some of the most effective and straightforward quantitative techniques for modeling Earth surface processes. By emphasizing a core set of equations and solution techniques, the book presents state-of-the-art models currently employed in Earth surface process research, as well as a set of simple but practical research tools. Detailed case studies demonstrate application of the methods to a wide variety of processes including hillslope, fluvial, aeolian, glacial, tectonic, and climatic systems. Exercises at the end of each chapter begin with simple calculations and then progress to more sophisticated problems that require computer programming. All the necessary computer codes are available online at www.cambridge.org/9780521855976. Assuming some knowledge of calculus and basic programming experience, this quantitative textbook is designed for advanced geomorphology courses and as a reference book for professional researchers in Earth and planetary science looking for a quantitative approach to Earth surface processes.

Decadal Seasonal Shifts of Precipitation and Temperature in TRMM and AIRS Data

NASA Technical Reports Server (NTRS)

Savtchenko, Andrey; Huffman, George; Meyer, David; Vollmer, Bruce

2018-01-01

We present results from an analysis of seasonal phase shifts in the global precipitation and surface temperatures. We use data from the TRMM (Tropical Rainfall Measuring Mission) Multi-satellite Precipitation Algorithm (TMPA), and the Atmospheric Infrared Sounder (AIRS) on Aqua satellite, all hosted at NASA Goddard Earth Science Data and Information Services Center (GES DISC). We explore the information content and data usability by first aggregating daily grids from the entire records of both missions to pentad (5-day) series which are then processed using Singular Value Decomposition approach. A strength of this approach is the normalized principal components that can then be easily converted from real to complex time series. Thus, we can separate the most informative, the seasonal, components and analyze unambiguously for potential seasonal phase drifts. TMPA and AIRS records represent correspondingly 20 and 15 years of data, which allows us to run simple “phase learning†from the first 5 years of records and use it as reference. The most recent 5 years are then phase-compared with the reference. We demonstrate that the seasonal phase of global precipitation and surface temperatures has been stable in the past two decades. However, a small global trend of delayed precipitation, and earlier arrival of surface temperatures seasons, are detectable at 95% confidence level. Larger phase shifts are detectable at regional level, in regions recognizable from the Eigen vectors to having strong seasonal patterns. For instance, in Central North America, including the North American Monsoon region, confident phase shifts of 1-2 days per decade are detected at 95% confidence level. While seemingly symbolic, these shifts are indicative of larger changes in the Earth Climate System. We thus also demonstrate a potential usability scenario of Earth Science Data Records curated at the NASA GES DISC in partnership with Earth Science Missions.

DAsHER CD: Developing a Data-Oriented Human-Centric Enterprise Architecture for EarthCube

Yang, C. P.; Yu, M.; Sun, M.; Qin, H.; Robinson, E.

2015-12-01

One of the biggest challenges that face Earth scientists is the resource discovery, access, and sharing in a desired fashion. EarthCube is targeted to enable geoscientists to address the challenges by fostering community-governed efforts that develop a common cyberinfrastructure for the purpose of collecting, accessing, analyzing, sharing and visualizing all forms of data and related resources, through the use of advanced technological and computational capabilities. Here we design an Enterprise Architecture (EA) for EarthCube to facilitate the knowledge management, communication and human collaboration in pursuit of the unprecedented data sharing across the geosciences. The design results will provide EarthCube a reference framework for developing geoscience cyberinfrastructure collaborated by different stakeholders, and identifying topics which should invoke high interest in the community. The development of this EarthCube EA framework leverages popular frameworks, such as Zachman, Gartner, DoDAF, and FEAF. The science driver of this design is the needs from EarthCube community, including the analyzed user requirements from EarthCube End User Workshop reports and EarthCube working group roadmaps, and feedbacks or comments from scientists obtained by organizing workshops. The final product of this Enterprise Architecture is a four-volume reference document: 1) Volume one is this document and comprises an executive summary of the EarthCube architecture, serving as an overview in the initial phases of architecture development; 2) Volume two is the major body of the design product. It outlines all the architectural design components or viewpoints; 3) Volume three provides taxonomy of the EarthCube enterprise augmented with semantics relations; 4) Volume four describes an example of utilizing this architecture for a geoscience project.

Non-linearity of geocentre motion and its impact on the origin of the terrestrial reference frame

NASA Astrophysics Data System (ADS)

Dong, Danan; Qu, Weijing; Fang, Peng; Peng, Dongju

2014-08-01

The terrestrial reference frame is a cornerstone for modern geodesy and its applications for a wide range of Earth sciences. The underlying assumption for establishing a terrestrial reference frame is that the motion of the solid Earth's figure centre relative to the mass centre of the Earth system on a multidecadal timescale is linear. However, past international terrestrial reference frames (ITRFs) showed unexpected accelerated motion in their translation parameters. Based on this underlying assumption, the inconsistency of relative origin motions of the ITRFs has been attributed to data reduction imperfection. We investigated the impact of surface mass loading from atmosphere, ocean, snow, soil moisture, ice sheet, glacier and sea level from 1983 to 2008 on the geocentre variations. The resultant geocentre time-series display notable trend acceleration from 1998 onward, in particular in the z-component. This effect is primarily driven by the hydrological mass redistribution in the continents (soil moisture, snow, ice sheet and glacier). The acceleration is statistically significant at the 99 per cent confidence level as determined using the Mann-Kendall test, and it is highly correlated with the satellite laser ranging determined translation series. Our study, based on independent geophysical and hydrological models, demonstrates that, in addition to systematic errors from analysis procedures, the observed non-linearity of the Earth-system behaviour at interannual timescales is physically driven and is able to explain 42 per cent of the disparity between the origins of ITRF2000 and ITRF2005, as well as the high level of consistency between the ITRF2005 and ITRF2008 origins.

The Effects of Earth Science Programs on Student Knowledge and Interest in Earth Science

NASA Astrophysics Data System (ADS)

Wilson, A.

2016-12-01

Ariana Wilson, Chris Skinner, Chris Poulsen Abstract For many years, academic programs have been in place for the instruction of young students in the earth sciences before they undergo formal training in high school or college. However, there has been little formal assessment of the impacts of these programs on student knowledge of the earth sciences and their interest in continuing with earth science. On August 6th-12th 2016 I will attend the University of Michigan's annual Earth Camp, where I will 1) ascertain high school students' knowledge of earth science-specifically atmospheric structure and wind patterns- before and after Earth Camp, 2) record their opinions about earth science before and after Earth Camp, and 3) record how the students feel about how the camp was run and what could be improved. I will accomplish these things through the use of surveys asking the students questions about these subjects. I expect my results will show that earth science programs like Earth Camp deepen students' knowledge of and interest in earth science and encourage them to continue their study of earth science in the future. I hope these results will give guidance on how to conduct future learning programs and how to recruit more students to become earth scientists in the future.

Rising Above the Storm: DIG TEXAS

NASA Astrophysics Data System (ADS)

Ellins, K. K.; Miller, K. C.; Bednarz, S. W.; Mosher, S.

2011-12-01

For a decade Texas educators, scientists and citizens have shown a commitment to earth science education through planning at the national and state levels, involvement in earth science curriculum and teacher professional development projects, and the creation of a model senior level capstone Earth and Space Science course first offered in 2010 - 2011. The Texas state standards for Earth and Space Science demonstrate a shift to rigorous content, career relevant skills and use of 21st century technology. Earth and Space Science standards also align with the Earth Science, Climate and Ocean Literacy framework documents. In spite of a decade of progress K-12 earth science education in Texas is in crisis. Many school districts do not offer Earth and Space Science, or are using the course as a contingency for students who fail core science subjects. The State Board for Educator Certification eliminated Texas' secondary earth science teacher certification in 2009, following the adoption of the new Earth and Space Science standards. This makes teachers with a composite teacher certification (biology, physics and chemistry) eligible to teach Earth and Space Science, as well other earth science courses (e.g., Aquatic Science, Environmental Systems/Science) even if they lack earth science content knowledge. Teaching materials recently adopted by the State Board of Education do not include Earth and Space Science resources. In July 2011 following significant budget cuts at the 20 Education Service Centers across Texas, the Texas Education Agency eliminated key staff positions in its curriculum division, including science. This "perfect storm" has created a unique opportunity for a university-based approach to confront the crisis in earth science education in Texas which the Diversity and Innovation in the Geosciences (DIG) TEXAS alliance aims to fulfill. Led by the Texas A&M University College of Geosciences and The University of Texas Jackson School of Geosciences, with initial assistance of the American Geophysical Union, the alliance comprises earth scientists and educators at higher education institutions across the state, and science teachers, united to improve earth science literacy (geoscience-earth, ocean, atmospheric, planetary, and geography) among Texas science teachers in order to attract individuals from groups underrepresented in STEM fields to pursue earth science as a career. Members of the alliance are affiliated with one of eight regional DIG TEXAS hub institutions. With an NSF planning grant, DIG TEXAS leaders created the DIG TEXAS brand, developed a project website, organized and held the first community meeting in March, 2011 at Exxon Mobil's Training Center in Houston. DIG TEXAS members have also delivered testimony to the State Board for Educator Certification in support of a new earth science teacher certification and collaborated on proposals that seek funding to support recommendations formulated at the community meeting.

METERON an international collaboration between ESA, NASA (University of Colorado), Roskosmos and DLR. It intends to use the ISS as a test bed to simulate an orbiter around another heavenly body (for example Mars), under directives from Mission Control on Earth. Astronauts on the orbiter will project their human initiative and instinct, in realtime, onto the surface of the heavenly body (simulated by an analog site on the Earth) through robotic device(s) to perform science or engineering tasks. This type of real-time control is not possible directly from Earth due to the One Way Light Time delay in communications. METERON operations are managed by B.USOC since December 2011 as Facility Reference Centre.

2015-12-01

"Beautiful Earth: Experiencing and Learning Science in an Engaging Way" was a 3-year project funded by NASA's Competitive Opportunities in Education and Public Outreach for Earth and Space Science. An outgrowth of Kenji Williams' BELLA GAIA performance, Beautiful Earth fostered a new approach to teaching by combining live music, data visualizations and Earth science with indigenous perspectives, and hands-on workshops for K-12 students at 5 science centers. Inspired by the "Overview Effect," described by many astronauts who were awestruck by seeing the Earth from space and their realization of the profound interconnectedness of Earth's life systems, Beautiful Earth leveraged the power of multimedia performance to serve as a springboard to engage K-12 students in hands-on Earth science and Native wisdom workshops. Results will be presented regarding student perceptions of Earth science, environmental issues, and indigenous ways of knowing from 3 years of evaluation data.

Diversity of Approaches to Structuring University-Based Earth System Science Education

NASA Astrophysics Data System (ADS)

Aron, J.; Ruzek, M.; Johnson, D. R.

2004-12-01

Over the past quarter century, the "Earth system science" paradigm has emerged among the interdisciplinary science community, emphasizing interactions among components hitherto considered within separate disciplines: atmosphere (air); hydrosphere (water); biosphere (life); lithosphere (land); anthroposphere (human dimension); and exosphere (solar system and beyond). How should the next generation of Earth system scientists learn to contribute to this interdisciplinary endeavor? There is no one simple answer. The Earth System Science Education program, funded by NASA, has addressed this question by supporting faculty at U.S. universities who develop new courses, curricula and degree programs in their institutional contexts. This report demonstrates the diversity of approaches to structuring university-based Earth system science education, focusing on the 18 current grantees of the Earth System Science Education Program for the 21st Century (ESSE21). One of the most fundamental characteristics is the departmental structure for teaching Earth system science. The "home" departments of the Earth system science faculty range from Earth sciences and physics to agronomy and social work. A brand-new institution created an interdisciplinary Institute for Earth Systems Science and Policy without traditional "parent" departments. Some institutions create new degree programs as majors or as minors while others work within existing degree programs to add or revise courses. A university may also offer multiple strands, such as a degree in the Science of the Earth System and a degree in the Human Dimensions of the Earth System. Defining a career path is extremely important to students considering Earth system science programs and a major institutional challenge for all programs in Earth system science education. How will graduate programs assess prospective students? How will universities and government agencies assess prospective faculty and scientists? How will government agencies allocate funds to interdisciplinary Earth system science and technology? Finally, how should the Earth system science education community evolve?

Earth Science Europe "Is Earth Science Europe an interesting and useful construct?"

NASA Astrophysics Data System (ADS)

Ludden, John

2015-04-01

In 2014 we managed to have a group of earth scientists from across the spectrum: from academic, survey, industry and government, pull together to create the first output for Earth Science Europe http://www.bgs.ac.uk/earthScienceEurope/downloads/EarthScienceEuropeBrochure.pdf In this document we stated that Earth scientists need a united, authoritative voice to enhance the status and impact of Earth science across Europe. The feeling was that there were many diverse infrastructure and research initiatives spanning the terrestrial and oceanic realms and science ranged from historical geology to active dynamics on Earth, and that a level of coordination and mutual knowledge sharing was necessary. In addition to a better understanding of the Earth in general, we thought there was a need to have Earth Science Europe develop a strategic research capacity in geohazards, georesources and environmental earth sciences, through a roadmap addressing fundamental and societal challenges. This would involve a robust research infrastructure to deliver strategic goals, enabling inspirational research and promoting solutions to societal challenges. In this talk I will propose some next steps and discuss what this "authoritative voice" could look like and ask the question - "is Earth Science Europe and interesting and useful concept?"

ARCSTONE: Accurate Calibration of Lunar Spectral Reflectance from space

Calibration accuracy and consistency are key on-orbit performance metrics for Earth observing sensors. The accuracy and consistency of measurements across multiple instruments in low Earth and geostationary orbits are directly connected to the scientific understanding of complex systems, such as Earth's weather and climate. Recent studies have demonstrated the quantitative impacts of observational accuracy on the science data products [1] and the ability to detect climate change trends for essential climate variables (e.g., Earth's radiation budget, cloud feedback, and long-term trends in cloud parameters) [2, 3]. It is common for sensors to carry references for calibration at various wavelengths onboard, but these can be subject to degradation and increase mass and risk. The Moon can be considered a natural solar diffuser in space. Establishing the Moon as an on-orbit high-accuracy calibration reference enables broad intercalibration opportunities, as the lunar reflectance is time-invariant and can be directly measured by most Earth-observing instruments. Existing approaches to calibrate sensors against the Moon can achieve stabilities of a tenth of a percent over a decade, as demonstrated by the SeaWIFS. However, the current lunar calibration quality, with 5 - 10% bias, depends on the photometric model of the Moon [4]. Significant improvements in the lunar reference are possible and are necessary for climate-level absolute calibrations using the Moon. The ARCSTONE instrument will provide a reliable reference for high-accuracy on-orbit calibration for reflected solar instruments. An orbiting spectrometer flying on a CubeSat in low Earth orbit will provide lunar spectral reflectance with accuracy < 0.5% (k = 1), sufficient to establish an SI-traceable absolute lunar calibration standard for past, current, and future Earth weather and climate sensors. The ARCSTONE team will present the instrument design status and path forward for development, building, calibration and testing. [1] Lyapustin, A. Y. et al., 2014, Atmos. Meas.

Large-Scale Science Observatories: Building on What We Have Learned from USArray

NASA Astrophysics Data System (ADS)

Woodward, R.; Busby, R.; Detrick, R. S.; Frassetto, A.

2015-12-01

With the NSF-sponsored EarthScope USArray observatory, the Earth science community has built the operational capability and experience to tackle scientific challenges at the largest scales, such as a Subduction Zone Observatory. In the first ten years of USArray, geophysical instruments were deployed across roughly 2% of the Earth's surface. The USArray operated a rolling deployment of seismic stations that occupied ~1,700 sites across the USA, made co-located atmospheric observations, occupied hundreds of sites with magnetotelluric sensors, expanded a backbone reference network of seismic stations, and provided instruments to PI-led teams that deployed thousands of additional seismic stations. USArray included a comprehensive outreach component that directly engaged hundreds of students at over 50 colleges and universities to locate station sites and provided Earth science exposure to roughly 1,000 landowners who hosted stations. The project also included a comprehensive data management capability that received, archived and distributed data, metadata, and data products; data were acquired and distributed in real time. The USArray project was completed on time and under budget and developed a number of best practices that can inform other large-scale science initiatives that the Earth science community is contemplating. Key strategies employed by USArray included: using a survey, rather than hypothesis-driven, mode of observation to generate comprehensive, high quality data on a large-scale for exploration and discovery; making data freely and openly available to any investigator from the very onset of the project; and using proven, commercial, off-the-shelf systems to ensure a fast start and avoid delays due to over-reliance on unproven technology or concepts. Scope was set ambitiously, but managed carefully to avoid overextending. Configuration was controlled to ensure efficient operations while providing consistent, uniform observations. Finally, community governance structures were put in place to ensure a focus on science needs and goals, to provide an informed review of the project's results, and to carefully balance consistency of observations with technical evolution. We will summarize lessons learned from USArray and how these can be applied to future efforts such as SZO.

Planetary Science datasets, beyond the change in the last two decades from physical volumes to internet-accessible archives, still face the problem of large-scale processing and analytics (e.g. Rossi et al., 2014, Gaddis and Hare, 2015). PlanetServer, the Planetary Science Data Service of the EC-funded EarthServer-2 project (#654367) tackles the planetary Big Data analytics problem with an array database approach (Baumann et al., 2014). It is developed to serve a large amount of calibrated, map-projected planetary data online, mainly through Open Geospatial Consortium (OGC) Web Coverage Processing Service (WCPS) (e.g. Rossi et al., 2014; Oosthoek et al., 2013; Cantini et al., 2014). The focus of the H2020 evolution of PlanetServer is still on complex multidimensional data, particularly hyperspectral imaging and topographic cubes and imagery. In addition to hyperspectral and topographic from Mars (Rossi et al., 2014), the use of WCPS is applied to diverse datasets on the Moon, as well as Mercury. Other Solar System Bodies are going to be progressively available. Derived parameters such as summary products and indices can be produced through WCPS queries, as well as derived imagery colour combination products, dynamically generated and accessed also through OGC Web Coverage Service (WCS). Scientific questions translated into queries can be posed to a large number of individual coverages (data products), locally, regionally or globally. The new PlanetServer system uses the the Open Source Nasa WorldWind (e.g. Hogan, 2011) virtual globe as visualisation engine, and the array database Rasdaman Community Edition as core server component. Analytical tools and client components of relevance for multiple communities and disciplines are shared across service such as the Earth Observation and Marine Data Services of EarthServer. The Planetary Science Data Service of EarthServer is accessible on http://planetserver.eu. All its code base is going to be available on GitHub, on https://github.com/planetserver References: Baumann, P., et al.

ESIP Federation: A Case Study on Enabling Collaboration Infrastructure to Support Earth Science Informatics Communities

NASA Astrophysics Data System (ADS)

Robinson, E.; Meyer, C. B.; Benedict, K. K.

2013-12-01

A critical part of effective Earth science data and information system interoperability involves collaboration across geographically and temporally distributed communities. The Federation of Earth Science Information Partners (ESIP) is a broad-based, distributed community of science, data and information technology practitioners from across science domains, economic sectors and the data lifecycle. ESIP's open, participatory structure provides a melting pot for coordinating around common areas of interest, experimenting on innovative ideas and capturing and finding best practices and lessons learned from across the network. Since much of ESIP's work is distributed, the Foundation for Earth Science was established as a non-profit home for its supportive collaboration infrastructure. The infrastructure leverages the Internet and recent advances in collaboration web services. ESIP provides neutral space for self-governed groups to emerge around common Earth science data and information issues, ebbing and flowing as the need for them arises. As a group emerges, the Foundation quickly equips the virtual workgroup with a set of ';commodity services'. These services include: web meeting technology (Webex), a wiki and an email listserv. WebEx allows the group to work synchronously, dynamically viewing and discussing shared information in real time. The wiki is the group's primary workspace and over time creates organizational memory. The listserv provides an inclusive way to email the group and archive all messages for future reference. These three services lower the startup barrier for collaboration and enable automatic content preservation to allow for future work. While many of ESIP's consensus-building activities are discussion-based, the Foundation supports an ESIP testbed environment for exploring and evaluating prototype standards, services, protocols, and best practices. After community review of testbed proposals, the Foundation provides small seed funding and a toolbox of collaborative development resources including Amazon Web Services to quickly spin-up the testbed instance and a GitHub account for maintaining testbed project code enabling reuse. Recently, the Foundation supported development of the ESIP Commons (http://commons.esipfed.org), a Drupal-based knowledge repository for non-traditional publications to preserve community products and outcomes like white papers, posters and proceedings. The ESIP Commons adds additional structured metadata, provides attribution to contributors and allows those unfamiliar with ESIP a straightforward way to find information. The success of ESIP Federation activities is difficult to measure. The ESIP Commons is a step toward quantifying sponsor return on investment and is one dataset used in network map analysis of the ESIP community network, another success metric. Over the last 15 years, ESIP has continually grown and attracted experts in the Earth science data and informatics field becoming a primary locus of research and development on the application and evolution of Earth science data standards and conventions. As funding agencies push toward a more collaborative approach, the lessons learned from ESIP and the collaboration services themselves are a crucial component of supporting science research.

NASA's Glenn Research Center (GRC) defines and develops advanced technology for high priority national needs in communications technologies for application to aeronautics and space. GRC tasked Computer Networks and Software Inc. (CNS) to examine protocols and architectures for an In-Space Internet Node. CNS has developed a methodology for network reference models to support NASA's four mission areas: Earth Science, Space Science, Human Exploration and Development of Space (REDS), Aerospace Technology. This report applies the methodology to three space Internet-based communications scenarios for future missions. CNS has conceptualized, designed, and developed space Internet-based communications protocols and architectures for each of the independent scenarios. The scenarios are: Scenario 1: Unicast communications between a Low-Earth-Orbit (LEO) spacecraft inspace Internet node and a ground terminal Internet node via a Tracking and Data Rela Satellite (TDRS) transfer; Scenario 2: Unicast communications between a Low-Earth-Orbit (LEO) International Space Station and a ground terminal Internet node via a TDRS transfer; Scenario 3: Multicast Communications (or "Multicasting"), 1 Spacecraft to N Ground Receivers, N Ground Transmitters to 1 Ground Receiver via a Spacecraft.

The ongoing educational anomaly of earth science placement

Messina, P.; Speranza, P.; Metzger, E.P.; Stoffer, P.

2003-01-01

The geosciences have traditionally been viewed with less "aCademic prTstige" than other science curricula. Among the results of this perception are depressed K-16 enrollments, Earth Science assignments to lower-performing students, and relegation of these classes to sometimes under-qualified educators, all of which serve to confirm the widely-held misconceptions. An Earth Systems course developed at San Jos??e State University demonstrates the difficulty of a standard high school Earth science curriculum, while recognizing the deficiencies in pre-college Earth science education. Restructuring pre-college science curricula so that Earth Science is placed as a capstone course would greatly improve student understanding of the geosciences, while development of Earth systems courses that infuse real-world and hands-on learning at the college level is critical to bridging the information gap for those with no prior exposure to the Earth sciences. Well-crafted workshops for pre-service and inservice teachers of Earth Science can heIp to reverse the trends and unfortunate "sTatus" in geoscience education.

Our joint NASA GSFC/JPL/MSFC/STScI study team has used community-provided science goals to derive mission needs, requirements, and candidate mission architectures for a future large-aperture, non-cryogenic UVOIR space observatory. We describe the feasibility assessment of system thermal and dynamic stability for supporting coronagraphy. The observatory is in a Sun-Earth L2 orbit providing a stable thermal environment and excellent field of regard. Reference designs include a 36-segment 9.2 m aperture telescope that stows within a five meter diameter launch vehicle fairing. Performance needs developed under the study are traceable to a variety of reference designs including options for a monolithic primary mirror.

Earth system science: A program for global change

NASA Technical Reports Server (NTRS)

1989-01-01

The Earth System Sciences Committee (ESSC) was appointed to consider directions for the NASA Earth-sciences program, with the following charge: review the science of the Earth as a system of interacting components; recommend an implementation strategy for Earth studies; and define the role of NASA in such a program. The challenge to the Earth system science is to develop the capability to predict those changes that will occur in the next decade to century, both naturally and in response to human activity. Sustained, long-term measurements of global variables; fundamental descriptions of the Earth and its history; research foci and process studies; development of Earth system models; an information system for Earth system science; coordination of Federal agencies; and international cooperation are examined.

Approaches for Improving Earth System Science Education in Middle Schools and High Schools in the United States (Invited)

NASA Astrophysics Data System (ADS)

Adams, P. E.

2009-12-01

Earth system science is an often neglected subject in the US science curriculum. The state of Kansas State Department of Education, for example, has provided teachers with a curriculum guide for incorporating earth system science as an ancillary topic within the subjects of physics, chemistry, and the biological sciences. While this does provide a means to have earth system science within the curriculum, it relegates earth system science topics to a secondary status. In practice, earth system science topics are considered optional or only taught if there is time within an already an overly crowded curriculum. Given the importance of developing an educated citizenry that is capable of understanding, coping, and deciding how to live in a world where climate change is a reality requires a deeper understanding of earth system science. The de-emphasis of earth system science in favor of other science disciplines makes it imperative to seek opportunities to provide teachers, whose primary subject is not earth system science, with professional development opportunities to develop content knowledge understanding of earth system science, and pedagogical content knowledge (i.e. effective strategies for teaching earth system science). This is a noble goal, but there is no single method. At Fort Hays State University we have developed multiple strategies from face-to-face workshops, on-line coursework, and academic year virtual and face-to-face consultations with in-service and pre-service teachers. A review of the techniques and measures of effectiveness (based on teacher and student performance), and strengths and limitations of each method will be presented as an aid to other institutions and programs seeking to improve the teaching and learning of earth system science in their region.

Validation of Radiometric Standards for the Laboratory Calibration of Reflected-Solar Earth Observing Satellite Instruments

Butler, James J.; Johnson, B. Carol; Rice, Joseph P.; Brown, Steven W.; Barnes, Robert A.

2007-01-01

Historically, the traceability of the laboratory calibration of Earth-observing satellite instruments to a primary radiometric reference scale (SI units) is the responsibility of each instrument builder. For the NASA Earth Observing System (EOS), a program has been developed using laboratory transfer radiometers, each with its own traceability to the primary radiance scale of a national metrology laboratory, to independently validate the radiances assigned to the laboratory sources of the instrument builders. The EOS Project Science Office also developed a validation program for the measurement of onboard diffuse reflecting plaques, which are also used as radiometric standards for Earth-observing satellite instruments. Summarized results of these validation campaigns, with an emphasis on the current state-of-the-art uncertainties in laboratory radiometric standards, will be presented. Future mission uncertainty requirements, and possible enhancements to the EOS validation program to ensure that those uncertainties can be met, will be presented.

Problems in the space and earth science programs are examined. Changes in the research environment and requirements for the space and earth sciences, for example from small Explorer missions to multispacecraft missions, have been observed. The need to expand the computational capabilities for space and earth sciences is discussed. The effects of fluctuations in funding, program delays, the limited number of space flights, and the development of the Space Station on research in the areas of astronomy and astrophysics, planetary exploration, solar and space physics, and earth science are analyzed. The recommendations of the Space and Earth Science Advisory Committee on the development and maintenance of effective space and earth sciences programs are described.

The effects of a professional development geoscience education institute upon secondary school science teachers in Puerto Rico

NASA Astrophysics Data System (ADS)

Llerandi Roman, Pablo Antonio

The geographic and geologic settings of Puerto Rico served as the context to develop a mixed methods investigation on: (1) the effects of a five-day long constructivist and field-based earth science education professional development institute upon 26 secondary school science teachers' earth science conceptual knowledge, perceptions of fieldwork, and beliefs about teaching earth science; and (2) the implementation of participants' newly acquired knowledge and experience in their science lessons at school. Qualitative data included questionnaires, semi-structured interviews, reflective journals, pre-post concept maps, and pre-post lesson plans. The Geoscience Concept Inventory and the Science Outdoor Learning Environment Inventory were translated into Spanish and culturally validated to collect quantitative data. Data was analyzed through a constructivist grounded theory methodology, descriptive statistics, and non-parametric methods. Participants came to the institute with serious deficiencies in earth science conceptual understanding, negative earth science teaching perspectives, and inadequate earth science teaching methodologies. The institute helped participants to improve their understanding of earth science concepts, content, and processes mostly related to the study of rocks, the Earth's structure, plate tectonics, maps, and the geology of Puerto Rico. Participants also improved their earth science teaching beliefs, perceptions on field-based education, and reflected on their environmental awareness and social responsibility. Participants greatly benefited from the field-based learning environment, inquiry-based teaching approaches modeled, the attention given to their affective domain, and reflections on their teaching practice as part of the institute's activities. The constructivist learning environment and the institute's contextualized and meaningful learning conceptual model were effective in generating interest and confidence in earth science teaching. Some participants successfully integrated inquiry-based lessons on the nature of science and earth science at their schools, but were unsuccessful in integrating field trips. The lack of teacher education programs and the inadequacy of earth science conceptual and pedagogical understanding held by in-service teachers are the main barriers for effective earth science teaching in Puerto Rico. This study established a foundation for future earth science education projects for Latino teachers. Additionally, as a result of this investigation various recommendations were made to effectively implement earth science teacher education programs in Puerto Rico and internationally.

Strategy for earth explorers in global earth sciences

NASA Technical Reports Server (NTRS)

1988-01-01

The goal of the current NASA Earth System Science initiative is to obtain a comprehensive scientific understanding of the Earth as an integrated, dynamic system. The centerpiece of the Earth System Science initiative will be a set of instruments carried on polar orbiting platforms under the Earth Observing System program. An Earth Explorer program can open new vistas in the earth sciences, encourage innovation, and solve critical scientific problems. Specific missions must be rigorously shaped by the demands and opportunities of high quality science and must complement the Earth Observing System and the Mission to Planet Earth. The committee believes that the proposed Earth Explorer program provides a substantial opportunity for progress in the earth sciences, both through independent missions and through missions designed to complement the large scale platforms and international research programs that represent important national commitments. The strategy presented is intended to help ensure the success of the Earth Explorer program as a vital stimulant to the study of the planet.

Assessing the Interdisciplinary Use of Socioeconomic and Remote Sensing Data in the Earth Sciences

NASA Astrophysics Data System (ADS)

Chen, R. S.; Downs, R. R.; Schumacher, J.

2013-12-01

Remotely sensed data are widely used in Earth science research and applications not just to improve understanding of natural systems but also to elucidate interactions between natural and human systems and to model and predict human impacts on the environment, whether planned or unplanned. It is therefore often necessary for both remote sensing and socioeconomic data to be used together in both Earth science and social science research, for example in modeling past, present, and future land cover change, in assessing societal vulnerability to geophysical and climatological hazards, in measuring the human health impacts of air and water pollution, or in developing improved approaches to managing water, ecological, and other resources. The NASA Socioeconomic Data and Applications Center (SEDAC) was established as part of the Earth Observing System Data and Information System (EOSDIS) to facilitate access to and use of socioeconomic data in conjunction with remote sensing data in both research and applications. SEDAC provides access both to socioeconomic data that have been transformed into forms more readily usable by Earth scientists and other users, and to integrated datasets that incorporate both socioeconomic and remote sensing data. SEDAC data have been cited in at least 2,000 scientific papers covering a wide range of scientific disciplines and problem areas. In many cases, SEDAC data are cited in these papers along with other remote sensing datasets available from NASA or other sources. However, such citations do not necessarily indicate significant, integrated use of SEDAC and remote sensing data. To assess the level and type of integrated data use, we analyze a selection of recent SEDAC data citations in Earth science journals to characterize the ways in which SEDAC data have been used in the underlying research project and the paper itself. Papers were selected based on the presence of a SEDAC data citation and one or more keywords related to a remote sensing instrument or dataset. We assess if and how the SEDAC and remote sensing data are used together, e.g., in an empirical analysis, model, and/or visualization. We also ascertain the multidisciplinary backgrounds of the author or authors, as well as the Web of Science category and impact factor associated with the journal, to help characterize the user community and the overall scientific impact of the data use. Another issue is whether or not authors are formally citing SEDAC data and remote sensing in reference sections as opposed to referring to data informally, e.g., in figure captions. A key challenge in promoting the cross-disciplinary use of scientific data is the identification of ways in which scientists and other users not only access data from other disciplines but also use these data in their research. Objective assessment of scientific outputs such as the peer-reviewed scientific literature provides important insight into how individual scientists and scientific teams are taking advantage of the ongoing explosion in the variety and quantity of digital data from multiple disciplines to address pressing research problems and applications.

The Solid Earth Science ESDR System (SESES) project funded under the NASA MEaSUREs program produces and disseminates mature, long-term, calibrated and validated, GNSS based Earth Science Data Records (ESDRs) that encompass multiple diverse areas of interest in Earth Science, such as tectonic motion, transient slip and earthquake dynamics, as well as meteorology, climate, and hydrology. The ESDRs now span twenty-five years for the earliest stations and today are available for thousands of global and regional stations. Using a unified metadata database and a combination of GNSS solutions generated by two independent analysis centers, the project currently produces four long-term ESDR's: Geodetic Displacement Time Series: Daily, combined, cleaned and filtered, GIPSY and GAMIT long-term time series of continuous GPS station positions (global and regional) in the latest version of ITRF, automatically updated weekly. Geodetic Velocities: Weekly updated velocity field + velocity field histories in various reference frames; compendium of all model parameters including earthquake catalog, coseismic offsets, and postseismic model parameters (exponential or logarithmic). Troposphere Delay Time Series: Long-term time series of troposphere delay (30-min resolution) at geodetic stations, necessarily estimated during position time series production and automatically updated weekly. Seismogeodetic records for historic earthquakes: High-rate broadband displacement and seismic velocity time series combining 1 Hz GPS displacements and 100 Hz accelerometer data for select large earthquakes and collocated cGPS and seismic instruments from regional networks. We present several recent notable examples of the ESDR's usage: A transient slip study that uses the combined position time series to unravel "tremor-less" slow tectonic transient events. Fault geometry determination from geodetic slip rates. Changes in water resources across California's physiographic provinces at a spatial resolution of 75 km. Retrospective study of a southern California summer monsoon event.

Educational research strives to identify the pedagogies that promote student learning. However, the body of research identifying the characteristics of effective teacher preparation is "least strong for science," and is largely based on studies of the effectiveness of individual courses or workshops (NRC 2010). The National Research Council's "Preparing Teachers: Building Evidence for Strong Policy," (2010) provides a mandate for teacher education providers to conduct research on program-scale effectiveness. The high priority research agenda identified by the NRC is expected to elicit understanding of the aspects of teacher preparation that critically impact classroom student learning outcomes. The Laboratory Lens project is designed to identify effective practices in a teacher education program, with specific reference to the content domain of Earth science. Now in its fifth year, the Masters of Applied Science (MAS) program at UNL offers a variety of science courses, ranging from entomology to food science. The six-course Lab Earth series serves as the backbone of the Specialization for Science Educators within the MAS program, and provides comprehensive content coverage of all Earth science topics identified in the AAAS Benchmarks. "How People Learn," (NRC 2009) emphasizes that expert knowledge includes not only factual knowledge, but also the well-developed conceptual framework critical to the ability to, "remember, reason, and solve problems." A focus of our research is to document the process by which the transition from novice to expert takes place in Lab Earth's on-line teacher participants. A feature of our research design is the standardization of evaluation instruments across the six courses. We have used data derived from implementation of the Community of Inquiry Survey (COI) in pilot offerings to ensure that the course sequence is effective in developing a community of learners, while developing their content knowledge. A pre- and post- course Wilcoxan Signed Ranks Test is included in the battery of assessments to ensure that the courses achieve a statistically significant increase in participants' beliefs about their personal science teaching efficacy. The research design also includes the analysis of concept maps and content mastery assignments to assist in documentation of a teacher's transition from mastery of novice to expert knowledge. Content-based, course-specific pre and post knowledge surveys are included in the battery of assessments. In the analysis of on-line discussions, the project employs a textual analysis technique outlined in "The Rhetoric of Social Intervention," (RSI) (Opt and Gring 2009). RSI provides a promising analytical framework, especially when examining the development of understanding of scientific topics with societal implications, such as sustainability and climate change. The session provides a description of the integrated research design and data collection and analysis in the first year of this project.

Bridging the gap with a duel-credit Earth Science course

NASA Astrophysics Data System (ADS)

Van Norden, W.

2011-12-01

College-bound high school students rarely have any exposure to the Earth Sciences. Earth Science may be offered to Middle School students. What is offered in High School, however, is usually a watered-down course offered to the weakest students. Meanwhile, our best and brightest students are steered towards biology, chemistry, and physics, what most schools consider the "real sciences". As a direct result, our population is not literate in the Earth Sciences and few students choose to study the Earth Science in college. One way to counteract this trend is to offer a rigorous capstone Earth Science course to High School Juniors and Seniors. Offering a course does not guarantee enrollment, however. Top science students are too busy taking Advanced Placement courses to consider a non-AP course. For that reason, the best way to lure top students into studying Earth Science is to create a duel-credit course, for which students receive both high school and college credit. A collaboration between high school teachers and college professors can result in a quality Earth Science course that bridges the huge gap that now exists between middle school science and college Earth Science. Harvard-Westlake School has successfully offered a duel-credit course with UCLA, and has created a model that can be used by other schools.

An Analysis of Misconceptions in Science Textbooks: Earth science in England and Wales

NASA Astrophysics Data System (ADS)

King, Chris John Henry

2010-03-01

Surveys of the earth science content of all secondary (high school) science textbooks and related publications used in England and Wales have revealed high levels of error/misconception. The 29 science textbooks or textbook series surveyed (51 texts in all) showed poor coverage of National Curriculum earth science and contained a mean level of one earth science error/misconception per page. Science syllabuses and examinations surveyed also showed errors/misconceptions. More than 500 instances of misconception were identified through the surveys. These were analysed for frequency, indicating that those areas of the earth science curriculum most prone to misconception are sedimentary processes/rocks, earthquakes/Earth's structure, and plate tectonics. For the 15 most frequent misconceptions, examples of quotes from the textbooks are given, together with the scientific consensus view, a discussion, and an example of a misconception of similar significance in another area of science. The misconceptions identified in the surveys are compared with those described in the literature. This indicates that the misconceptions found in college students and pre-service/practising science teachers are often also found in published materials, and therefore are likely to reinforce the misconceptions in teachers and their students. The analysis may also reflect the prevalence earth science misconceptions in the UK secondary (high school) science-teaching population. The analysis and discussion provide the opportunity for writers of secondary science materials to improve their work on earth science and to provide a platform for improved teaching and learning of earth science in the future.

Development of Ground Reference GIS for Assessing Land Cover Maps of Northeast Yellowstone National Park

NASA Technical Reports Server (NTRS)

Spruce, Joe; Warner, Amanda; Terrie, Greg; Davis, Bruce

2001-01-01

GIS technology and ground reference data often play vital roles in assessing land cover maps derived from remotely sensed data. This poster illustrates these roles, using results from a study done in Northeast Yellowstone National Park. This area holds many forest, range, and wetland cover types of interest to park managers. Several recent studies have focused on this locale, including the NASA Earth Observations Commercial Applications Program (EOCAP) hyperspectral project performed by Yellowstone Ecosystems Studies (YES) on riparian and in-stream habitat mapping. This poster regards a spin-off to the EOCAP project in which YES and NASA's Earth Science Applications Directorate explored the potential for synergistic use of hyperspecral, synthetic aperture radar, and multiband thermal imagery in mapping land cover types. The project included development of a ground reference GIS for site-specific data needed to evaluate maps from remotely sensed imagery. Field survey data included reflectance of plant communities, native and exotic plant species, and forest health conditions. Researchers also collected GPS points, annotated aerial photographs, and took hand held photographs of reference sites. The use of ESRI, ERDAS, and ENVI software enabled reference data entry into a GIS for comparision to georeferenced imagery and thematic maps. The GIS-based ground reference data layers supported development and assessment of multiple maps from remotely sensed data sets acquired over the study area.

NASA's Earth Science Flight Program Meets the Challenges of Today and Tomorrow

NASA Technical Reports Server (NTRS)

Ianson, Eric E.

2016-01-01

NASA's Earth science flight program is a dynamic undertaking that consists of a large fleet of operating satellites, an array of satellite and instrument projects in various stages of development, a robust airborne science program, and a massive data archiving and distribution system. Each element of the flight program is complex and present unique challenges. NASA builds upon its successes and learns from its setbacks to manage this evolving portfolio to meet NASA's Earth science objectives. NASA fleet of 16 operating missions provide a wide range of scientific measurements made from dedicated Earth science satellites and from instruments mounted to the International Space Station. For operational missions, the program must address issues such as an aging satellites operating well beyond their prime mission, constellation flying, and collision avoidance with other spacecraft and orbital debris. Projects in development are divided into two broad categories: systematic missions and pathfinders. The Earth Systematic Missions (ESM) include a broad range of multi-disciplinary Earth-observing research satellite missions aimed at understanding the Earth system and its response to natural and human-induced forces and changes. Understanding these forces will help determine how to predict future changes, and how to mitigate or adapt to these changes. The Earth System Science Pathfinder (ESSP) program provides frequent, regular, competitively selected Earth science research opportunities that accommodate new and emerging scientific priorities and measurement capabilities. This results in a series of relatively low-cost, small-sized investigations and missions. Principal investigators whose scientific objectives support a variety of studies lead these missions, including studies of the atmosphere, oceans, land surface, polar ice regions, or solid Earth. This portfolio of missions and investigations provides opportunity for investment in innovative Earth science that enhances NASA's capability for better understanding the current state of the Earth system. ESM and ESSP projects often involve partnerships with other US agencies and/or international organizations. This adds to the complexity of mission development, but allows for a greater scientific return on NASA's investments. The Earth Science Airborne Science Program provides manned and unmanned aircraft systems that further science and advance the use of satellite data. NASA uses these assets worldwide in campaigns to investigate extreme weather events, observe Earth system processes, obtain data for Earth science modeling activities, and calibrate instruments flying aboard Earth science spacecraft. The Airborne Science Program has six dedicated aircraft and access to many other platforms. The Earth Science Multi-Mission Operations program acquires, preserves, and distributes observational data from operating spacecraft to support Earth Science research focus areas. The Earth Observing System Data and Information System (EOSDIS), which has been in operations since 1994, primarily accomplishes this. EOSDIS acquires, processes, archives, and distributes Earth Science data and information products. The archiving of NASA Earth Science information happens at eight Distributed Active Archive Centers (DAACs) and four disciplinary data centers located across the United States. The DAACs specialize by topic area, and make their data available to researchers around the world. The DAACs currently house over 9 petabytes of data, growing at a rate of 6.4 terabytes per day. NASA's current Earth Science portfolio is responsive to the National Research Council (NRC) 2007 Earth Science Decadal Survey and well as the 2010 NASA Response to President Obama's Climate Plan. As the program evolves into the future it will leverage the lessons learned from the current missions in operations and development, and plan for adjustments to future objectives in response to the anticipated 2017 NRC Decadal Survey.

ESSEA On-Line Courses and the WestEd Eisenhower Regional Consortium (WERC)

Rognier, E.

2001-12-01

The WestEd Eisenhower Regional Consortium (WERC) is in its second year of offering two Earth Systems Science On-line Graduate courses from IGES - one for High School teachers, and one for Middle School teachers. These high-quality courses support WERC's commitment to "supporting increased scientific and mathematical literacy among our nation's youth through services and other support aimed at enhancing the efforts of those who provide K-12 science and mathematics education." WERC has been able to use its EdGateway online community network to offer these courses to environmental education and science teachers nationwide. Through partnerships with the North American Association for Environmental Education (NAAEE), the National Environmental Education Advancement Project (NEEAP), and other regional, state and local science and environmental education organizations, WERC has a broad reach in connecting with science educators nationwide. WERC manages several state and national listservs, which enable us to reach thousands of educators with information about the courses. EdGateway also provides a private online community in which we offer the courses. WERC partners with two Master Teachers from Utah, who facilitate the courses, and with the Center for Science and Mathematics Education at Weber State University, who provides low-cost graduate credit for the courses. Our students have included classroom teachers from upper elementary through high school, community college science teachers, and environmental science center staff who provide inservice for teachers. Educators from Hawaii to New Jersey have provided diverse personal experiences of Earth Systems Science events, and add richness to the online discussions. Two Earth Science Experts, Dr. Rick Ford from Weber State University, and Dr. Art Sussman from WestEd also contribute to the high caliber of learning the students experience in the courses. (Dr. Sussman's book, Dr. Art's Guide to Planet Earth, is used as one of the texts for our courses.) This is our first effort in offering online courses, and we are learning valuable lessons about recruitment, retention, team-building, and facilitating discussions for classes with no "face to face" component. This format is both rich and challenging, with teammates from diverse geographic regions and timezones, with a variety of connectivity and accessibility issues. In this second year of offering the courses, we are pleased to have students referred by former participants, anxious to take this "highly recommended" course!

Gravity Probe-B (GP-B) is the relativity experiment being developed at Stanford University to test two extraordinary predictions of Albert Einstein's general theory of relativity. The experiment will measure, very precisely, the expected tiny changes in the direction of the spin axes of four gyroscopes contained in an Earth-orbiting satellite at a 400-mile altitude. So free are the gyroscopes from disturbance that they will provide an almost perfect space-time reference system. They will measure how space and time are very slightly warped by the presence of the Earth, and, more profoundly, how the Earth's rotation very slightly drags space-time around with it. These effects, though small for the Earth, have far-reaching implications for the nature of matter and the structure of the Universe. GP-B is among the most thoroughly researched programs ever undertaken by NASA. This is the story of a scientific quest in which physicists and engineers have collaborated closely over many years. Inspired by their quest, they have invented a whole range of technologies -- technologies that are already enlivening other branches of science and engineering. Scheduled for launch in 2003 and managed for NASA by Marshall Space Flight Center, development of the GP-B is the responsibility of Stanford University, with major subcontractor Lockheed Martin Corporation.

Scheduled for launch in 2003 and managed for NASA by the Marshall Space Flight Center, development of GP-B is the responsibility of Stanford University, with major subcontractor Lockheed Martin Corporation.

Finding Common Ground Between Earth Scientists and Evangelical Christians

NASA Astrophysics Data System (ADS)

Grant Ludwig, L.

2015-12-01

In recent decades there has been some tension between earth scientists and evangelical Christians in the U.S., and this tension has spilled over into the political arena and policymaking on important issues such as climate change. From my personal and professional experience engaging with both groups, I find there is much common ground for increasing understanding and communicating the societal relevance of earth science. Fruitful discussions can arise from shared values and principles, and common approaches to understanding the world. For example, scientists and Christians are engaged in the pursuit of truth, and they value moral/ethical decision-making based on established principles. Scientists emphasize the benefits of research "for the common good" while Christians emphasize the value of doing "good works". Both groups maintain a longterm perspective: Christians talk about "the eternal" and geologists discuss "deep time". Both groups understand the importance of placing new observations in context of prior understanding: scientists diligently reference "the literature" while Christians quote "chapter and verse". And members of each group engage with each other in "fellowship" or "meetings" to create a sense of community and reinforce shared values. From my perspective, earth scientists can learn to communicate the importance and relevance of science more effectively by engaging with Christians in areas of common ground, rather than by trying to win arguments or debates.

New service of Earth Interactions offers sneak peek at work in progress

NASA Astrophysics Data System (ADS)

A new service of the all-electronic journal Earth Interactions (Web site http://EarthInter-actions.org) now provides online access to abstracts or preprints of selected papers being presented at various Earth system science conferences. The new service, “Earth Abstractions,” is separate from the peer-reviewed articles in Earth Interactions. The editors select the sessions that will be featured. AGU Spring Meeting abstracts are now highlighted on the site.The abstract titles in Earth Abstractions will link directly to online extended abstracts or preprints located on the authors' home servers if such abstracts are made available. As the author updates the preprint and posts it to the same URL, Earth Abstractions will continue to feature the most recent information from the author related to that work. Readers can preview an author's work as it evolves prior to the meeting as well as refer to it for a year after the meeting has ended. This exchange also provides a means for authors to receive positive feedback on their papers independent of the conference session, which may help those who plan to submit papers about their work to a peer-reviewed journal.

Snow Ecology

Jones, H. G.; Pomeroy, J. W.; Walker, D. A.; Hoham, R. W.

2001-01-01

In this volume, a multidisciplinary group of acknowledged experts fully intergrate the physical, chemical, and biological sciences to provide a complete understanding of the interrelationships between snow structure and life. This volume opens a new perspecitve on snow cover as a habitat for organisms under extreme environmental conditions and as a key factor in the ecology of much of the Earth's surface. The contributors describe the fundamental physical and small-scale chemical processes that characterize the evolution of snow and their influence on the life cycles of true snow organisms and the biota of cold regions with extended snow cover. The book further expands on the role of snow in the biosphere by the study of the relationship between snow and climate and the paleo-ecological evidence for the influence of past snow regimes on plant communities. Snow Ecology will form a main textbook on advanced courses in biology, ecology, geography, environmental science, and earth science where an important component is devoted to the study of the cryosphere. It will also be useful as a reference text for graduate students, researchers, and professionals at academic institutions and in government and nongovernmental agencies with environmental concerns.

2016-06-01

In the area of science education research, studies have attempted to investigate conceptions of learning, approaches to learning, and self-efficacy, mainly focusing on science in general or on specific subjects such as biology, physics, and chemistry. However, few empirical studies have probed students' earth science learning. This study aimed to explore the relationships among undergraduates' conceptions of, approaches to, and self-efficacy for learning earth science by adopting the structural equation modeling technique. A total of 268 Taiwanese undergraduates (144 females) participated in this study. Three instruments were modified to assess the students' conceptions of, approaches to, and self-efficacy for learning earth science. The results indicated that students' conceptions of learning made a significant contribution to their approaches to learning, which were consequently correlated with their learning self-efficacy. More specifically, students with stronger agreement that learning earth science involves applying the knowledge and skills learned to unknown problems were prone to possess higher confidence in learning earth science. Moreover, students viewing earth science learning as understanding earth science knowledge were more likely to adopt meaningful strategies to learn earth science, and hence expressed a higher sense of self-efficacy. Based on the results, practical implications and suggestions for future research are discussed.

Mainstream web standards now support science data too

NASA Astrophysics Data System (ADS)

Richard, S. M.; Cox, S. J. D.; Janowicz, K.; Fox, P. A.

2017-12-01

The science community has developed many models and ontologies for representation of scientific data and knowledge. In some cases these have been built as part of coordinated frameworks. For example, the biomedical communities OBO Foundry federates applications covering various aspects of life sciences, which are united through reference to a common foundational ontology (BFO). The SWEET ontology, originally developed at NASA and now governed through ESIP, is a single large unified ontology for earth and environmental sciences. On a smaller scale, GeoSciML provides a UML and corresponding XML representation of geological mapping and observation data. Some of the key concepts related to scientific data and observations have recently been incorporated into domain-neutral mainstream ontologies developed by the World Wide Web consortium through their Spatial Data on the Web working group (SDWWG). OWL-Time has been enhanced to support temporal reference systems needed for science, and has been deployed in a linked data representation of the International Chronostratigraphic Chart. The Semantic Sensor Network ontology has been extended to cover samples and sampling, including relationships between samples. Gridded data and time-series is supported by applications of the statistical data-cube ontology (QB) for earth observations (the EO-QB profile) and spatio-temporal data (QB4ST). These standard ontologies and encodings can be used directly for science data, or can provide a bridge to specialized domain ontologies. There are a number of advantages in alignment with the W3C standards. The W3C vocabularies use discipline-neutral language and thus support cross-disciplinary applications directly without complex mappings. The W3C vocabularies are already aligned with the core ontologies that are the building blocks of the semantic web. The W3C vocabularies are each tightly scoped thus encouraging good practices in the combination of complementary small ontologies. The W3C vocabularies are hosted on well known, reliable infrastructure. The W3C SDWWG outputs are being selectively adopted by the general schema.org discovery framework.

1991-01-01

Objectives and requirements for Earth rotation and reference frame studies in the 1990s are discussed. The objectives are to observe and understand interactions of air and water with the rotational dynamics of the Earth, the effects of the Earth's crust and mantle on the dynamics and excitation of Earth rotation variations over time scales of hours to centuries, and the effects of the Earth's core on the rotational dynamics and the excitation of Earth rotation variations over time scales of a year or longer. Another objective is to establish, refine and maintain terrestrial and celestrial reference frames. Requirements include improvements in observations and analysis, improvements in celestial and terrestrial reference frames and reference frame connections, and improved observations of crustal motion and mass redistribution on the Earth.

An ESIC? An Earth Science Information Center. Don't spell it. Say it. ESIC. It rhymes with seasick. You can find information in an information center, of course, and you'll find earth science information in an ESIC. That means information about the land that is the Earth, the land that is below the Earth, and in some instances, the space surrounding the Earth. The U.S. Geological Survey (USGS) operates a network of Earth Science Information Centers that sell earth science products and data. There are more than 75 ESIC's. Some are operated by the USGS, but most are in other State or Federal agencies. Each ESIC responds to requests for information received by telephone, letter, or personal visit. Your personal visit.

Beautiful Earth: Inspiring Native American students in Earth Science through Music, Art and Science

NASA Astrophysics Data System (ADS)

Casasanto, V.; Rock, J.; Hallowell, R.; Williams, K.; Angell, D.; Beautiful Earth

2011-12-01

The Beautiful Earth program, awarded by NASA's Competitive Opportunities in Education and Public Outreach for Earth and Space Science (EPOESS), is a live multi-media performance at partner science centers linked with hands-on workshops featuring Earth scientists and Native American experts. It aims to inspire, engage and educate diverse students in Earth science through an experience of viewing the Earth from space as one interconnected whole, as seen through the eyes of astronauts. The informal education program is an outgrowth of Kenji Williams' BELLA GAIA Living Atlas Experience (www.bellagaia.com) performed across the globe since 2008 and following the successful Earth Day education events in 2009 and 2010 with NASA's DLN (Digital Learning Network) http://tinyurl.com/2ckg2rh. Beautiful Earth takes a new approach to teaching, by combining live music and data visualizations, Earth Science with indigenous perspectives of the Earth, and hands-on interactive workshops. The program will utilize the emotionally inspiring multi-media show as a springboard to inspire participants to learn more about Earth systems and science. Native Earth Ways (NEW) will be the first module in a series of three "Beautiful Earth" experiences, that will launch the national tour at a presentation in October 2011 at the MOST science museum in collaboration with the Onandaga Nation School in Syracuse, New York. The NEW Module will include Native American experts to explain how they study and conserve the Earth in their own unique ways along with hands-on activities to convey the science which was seen in the show. In this first pilot run of the module, 110 K-12 students with faculty and family members of the Onandaga Nations School will take part. The goal of the program is to introduce Native American students to Earth Sciences and STEM careers, and encourage them to study these sciences and become responsible stewards of the Earth. The second workshop presented to participants will be the Spaceship Earth Scientist (SES) Module, featuring an Earth Scientist expert discussing the science seen in the presentation. Hands-on activities such as sea ice melting simulations will be held with participants. Results from these first pilot education experiences will be presented at the 2011 AGU.

Using the earth system for integrating the science curriculum

NASA Astrophysics Data System (ADS)

Mayer, Victor J.

Content and process instruction from the earth sciences has gone unrepresented in the world's science curricula, especially at the secondary level. As a result there is a serious deficiency in public understanding of the planet on which we all live. This lack includes national and international leaders in politics, business, and science. The earth system science effort now engaging the research talent of the earth sciences provides a firm foundation from the sciences for inclusion of earth systems content into the evolving integrated science curricula of this country and others. Implementing integrated science curricula, especially at the secondary level where potential leaders often have their only exposure to science, can help to address these problems. The earth system provides a conceptual theme as opposed to a disciplinary theme for organizing such integrated curricula, absent from prior efforts. The end of the cold war era is resulting in a reexamination of science and the influence it has had on our planet and society. In the future, science and the curricula that teach about science must seriously address the environmental and social problems left in the wake of over 100 years of preparation for military and economic war. The earth systems education effort provides one such approach to the modernization of science curricula. Earth science educators should assume leadership in helping to establish such curricula in this country and around the world.

Streletskiy, D. A.; Groisman, P. Y.; Shugart, H. H., Jr.; Gulev, S.; Maksyutov, S. S.; Qi, J.

2017-12-01

Since 2004, the Northern Eurasia Earth Science Partnership Initiative (NEESPI) - an interdisciplinary program of internationally-supported Earth systems and science research - has addressed large-scale and long-term manifestations of climate and environmental changes over Northern Eurasia and their impact on the Global Earth system. With 40 books and more than 1500 peer-reviewed journal publications to its credit, NEESPI's output can now be used to directly support decision-making for societal needs. Specifically, it was decided to shift gradually the foci of regional studies in Northern Eurasia towards applications with the following major Science Question: "What dynamic and interactive change(s) will affect societal well-being, activities, and health, and what might be the mitigation and adaptation strategies that could support sustainable development and decision-making activities in Northern Eurasia?" To answer this question requires a stronger socio-economic component in the ongoing and future regional studies focused on sustainable societal development under changing climatic and environmental conditions. The NEESPI Research Team has reorganized itself into "Northern Eurasia Future Initiative" (NEFI) and developed a new Science Plan released in June 2016. The Plan underwent a 6-month-long public review and was finalized at the end of 2016. Its description was thereafter split between two review papers: Groisman et al. (2017) and Monier et al. (2017). The first paper describes the Plan rationale and a new set of topical questions. The second paper describes a major modeling approach that will be employed in addressing the "what to do" questions of the NEFI Research (cf., presentation by Monier et al. at this Session). In the current presentation, we outline the new NEFI research foci and present latest NEFI findings including international projects in the Eurasian Arctic, boreal zone, and the Dry Land Belt of Northern Eurasia (cf., also presentations at sister-Session GC027).

This patch represents the essential elements associated with pressurized Earth science research aboard the International Space Station. At the top of the patch Klingon script spells out the acronym WORF making reference to the famed Star Trek character of the same name. In doing so it attests to the foresight, honor, integrity, and persistence of all those who made the WORF possible. To the right of the Klingon script is a single four pointed star in the form of a cross to honor the late Dr. Jack Estes and Dr. Dave Amsbury, the individuals most responsible for seeing to it that an optical quality, Earth science research window was added to the United States laboratory module, Destiny. The "flying eyeball" represents the ability of the ISS to allow scientists and astronauts to make and record continuous observations of natural and manmade processes on the surface of the Earth. The Destiny laboratory is depicted on the right of the patch above the Flag of the United States of America and highlights the position of the nadir looking, optical quality, science window in the module. The light emanating from the window from the lighted interior of the module appropriately illuminates the National Ensign for display during both day and night time. In the center of the patch, below the flying eyeball is a graphic representation of the WORF rack. A science instrument is mounted on the WORF payload shelf and is recording data of the Earth's surface through the nadir looking, science window over which the WORF rack is mounted. An astronaut represented by Mario Runco Jr., a designer, developer, and manager of the WORF and depicted as Star Trek's Mr. Spock, is to the left of the WORF rack and is shown in his flight suit with his STS-44 mission patch operating an imaging instrument, emphasizing the importance of astronaut participation to achieve the maximum scientific return from orbital research.

Progress and Setbacks in K-12 Earth and Space Science Education During the Past Decade

NASA Astrophysics Data System (ADS)

Geary, E.; Hoffman, M.; Stevermer, A.; Barstow, D.

2005-12-01

Since publication of the National Science Education Standards in 1996, key Earth and space science concepts have been incorporated into the science education standards in virtually every state. However, the degree to which Earth and space science standards have been implemented in actual classroom curriculum and state science assessments varies greatly from state to state. In a similar vein, the No Child Left Behind legislation calls for a highly qualified teacher in every classroom: in Idaho over 96 percent of high school teachers are certified to teach Earth science, while in Illinois, less than 42 percent of teachers are certified. Furthermore, in some states, like New York, approximately 20 percent of high school students will take introductory Earth science each year, while in other states, like Texas, less than 1 percent of high school students will take introductory Earth science each year. Why do we have this high degree of variability with respect to the teaching and learning of Earth science across the United States? The answer is complex, as there are many institutional, attitudinal, budgetary, and policy factors affecting the teaching of Earth and space sciences. This presentation will summarize data on the current status of Earth and space science education in the United States, discuss where progress has been made and where setbacks have occurred during the past decade, and provide some suggestions and ideas for improving access to high quality Earth and space science education courses, curricula, assessments, and teachers at the state and local level.

EPOS, the European Plate Observing System, is a long-term plan to facilitate the integrated use of data, data products, software and services, available from distributed Research Infrastructures (RI), for solid Earth science in Europe. Indeed, EPOS integrates a large number of existing European RIs belonging to several fields of the Earth science, from seismology to geodesy, near fault and volcanic observatories as well as anthropogenic hazards. The EPOS vision is that the integration of the existing national and trans-national research infrastructures will increase access and use of the multidisciplinary data recorded by the solid Earth monitoring networks, acquired in laboratory experiments and/or produced by computational simulations. The establishment of EPOS will foster the interoperability of products and services in the Earth science field to a worldwide community of users. Accordingly, the EPOS aim is to integrate the diverse and advanced European Research Infrastructures for solid Earth science, and build on new e-science opportunities to monitor and understand the dynamic and complex solid-Earth System. One of the EPOS Thematic Core Services (TCS), referred to as Satellite Data, aims at developing, implementing and deploying advanced satellite data products and services, mainly based on Copernicus data (namely Sentinel acquisitions), for the Earth science community. This work intends to present the technological enhancements, fostered by EPOS, to deploy effective satellite services in a harmonized and integrated way. In particular, the Satellite Data TCS will deploy five services, EPOSAR, GDM, COMET, 3D-Def and MOD, which are mainly based on the exploitation of SAR data acquired by the Sentinel-1 constellation and designed to provide information on Earth surface displacements. In particular, the planned services will provide both advanced DInSAR products (deformation maps, velocity maps, deformation time series) and value-added measurements (source model, 3D displacement maps, seismic hazard maps). Moreover, the services will release both on-demand and systematic products. The latter will be generated and made available to the users on a continuous basis, by processing each Sentinel-1 data once acquired, over a defined number of areas of interest; while the former will allow users to select data, areas, and time period to carry out their own analyses via an on-line platform. The satellite components will be integrated within the EPOS infrastructure through a common and harmonized interface that will allow users to search, process and share remote sensing images and results. This gateway to the satellite services will be represented by the ESA- Geohazards Exploitation Platform (GEP), a new cloud-based platform for the satellite Earth Observations designed to support the scientific community in the understanding of high impact natural disasters. Satellite Data TCS will use GEP as the common interface toward the main EPOS portal to provide EPOS users not only with data products but also with relevant processing and visualisation software, thus allowing users to gather and process on a cloud-computing infrastructure large datasets without any need to download them locally.

2015-01-01

Over the last 10-15 years, significant advances have been made in information management, there are an increasing number of individuals entering the field of information management as it applies to Geoscience and Remote Sensing data, and the field of informatics has come to its own. Informatics is the science and technology of applying computers and computational methods to the systematic analysis, management, interchange, and representation of science data, information, and knowledge. Informatics also includes the use of computers and computational methods to support decision making and applications. Earth Science Informatics (ESI, a.k.a. geoinformatics) is the application of informatics in the Earth science domain. ESI is a rapidly developing discipline integrating computer science, information science, and Earth science. Major national and international research and infrastructure projects in ESI have been carried out or are on-going. Notable among these are: the Global Earth Observation System of Systems (GEOSS), the European Commissions INSPIRE, the U.S. NSDI and Geospatial One-Stop, the NASA EOSDIS, and the NSF DataONE, EarthCube and Cyberinfrastructure for Geoinformatics. More than 18 departments and agencies in the U.S. federal government have been active in Earth science informatics. All major space agencies in the world, have been involved in ESI research and application activities. In the United States, the Federation of Earth Science Information Partners (ESIP), whose membership includes nearly 150 organizations (government, academic and commercial) dedicated to managing, delivering and applying Earth science data, has been working on many ESI topics since 1998. The Committee on Earth Observation Satellites (CEOS)s Working Group on Information Systems and Services (WGISS) has been actively coordinating the ESI activities among the space agencies.

An open-source textbook for teaching climate-related risk analysis using the R computing environment

NASA Astrophysics Data System (ADS)

Applegate, P. J.; Keller, K.

2015-12-01

Greenhouse gas emissions lead to increased surface air temperatures and sea level rise. In turn, sea level rise increases the risks of flooding for people living near the world's coastlines. Our own research on assessing sea level rise-related risks emphasizes both Earth science and statistics. At the same time, the free, open-source computing environment R is growing in popularity among statisticians and scientists due to its flexibility and graphics capabilities, as well as its large library of existing functions. We have developed a set of laboratory exercises that introduce students to the Earth science and statistical concepts needed for assessing the risks presented by climate change, particularly sea-level rise. These exercises will be published as a free, open-source textbook on the Web. Each exercise begins with a description of the Earth science and/or statistical concepts that the exercise teaches, with references to key journal articles where appropriate. Next, students are asked to examine in detail a piece of existing R code, and the exercise text provides a clear explanation of how the code works. Finally, students are asked to modify the existing code to produce a well-defined outcome. We discuss our experiences in developing the exercises over two separate semesters at Penn State, plus using R Markdown to interweave explanatory text with sample code and figures in the textbook.

However, this organic collaboration between researchers, educators, and students only flourishes with the reduction or elimination of technological barriers. The Magnetics Information Consortium (http://earthref.org/MagIC/) is a grass-roots cyberinfrastructure effort envisioned by the geo-, paleo-, and rock magnetic scientific community to archive their wealth of peer-reviewed raw data and interpretations from studies on natural and synthetic samples. MagIC is dedicated to facilitating scientific progress towards several highly multidisciplinary grand challenges and the MagIC Database team is currently beta testing a new MagIC Search Interface and API designed to be flexible enough for the incorporation of large heterogeneous datasets and for horizontal scalability to tens of millions of records and hundreds of requests per second. In an effort to reduce the barriers to effective collaboration, the search interface includes a simplified data model and upload procedure, support for online editing of datasets amongst team members, commenting by reviewers and colleagues, and automated contribution workflows and data retrieval through the API. This web application has been designed to generalize to other databases in MagIC's umbrella website (EarthRef.org) so the Geochemical Earth Reference Model (http://earthref.org/GERM/) portal, Seamount Biogeosciences Network (http://earthref.org/SBN/), EarthRef Digital Archive (http://earthref.org/ERDA/) and EarthRef Reference Database (http://earthref.org/ERR/) will benefit from its development.

Use of USGS earth-science products by county planning agencies in the San Francisco Bay region, California

USGS Publications Warehouse

Kockelman, William J.

1976-01-01

An inventory of the use of USGS products in selected planning studies, plans, ordinances, and other planning activities was made for eight counties in the San Francisco Bay region--a region of almost five million people. This inventory was designed to determine and document the use of the 87 earth-science information products prepared as a part of the San Francisco Bay Region Environment and Resources Planning Study (SFBRS). The inventory showed that: (1) all eight counties had planning staffs who were very familiar with SFBRS products and had made frequent use of such products; (2) all eight counties had prepared planning documents which cite SFBRS products; (3) the types of planning applications most often indicated were: geologic hazards studies, seismic safety and public safety plan elements, general reference, and the preparation and review of environmental impact reports and statements; (4) over 90 percent of the 87 SFBRS products were used at least once, and nine of the products were used over 30 times each for various county planning activities; and (5) at least 85 other USGS products were also used for various county planning activities. After the inventory, selected county officials, employees, and consultants were interviewed and asked--among other things--to indicate any problems in the use of the SFBRS products, to suggest improvements, and to identify any needed or desired earth-science information. The responses showed that: (1) the scales commonly used for working maps were 1:62,500 or larger and for plan implementation were 1:24,000 or larger; (2) only one county had a geologist on its planning staff, although six others had the benefit of geotechnical services from private consulting firms, county engineering staffs, or the State Division of Mines and Geology; (3) seven of the eight counties expressed some problems in using the products, primarily because of their small scale or lack of detail; (4) all eight counties expected to continue to use the products and expressed a need or desire for additional earth-science, engineering, or other information; (5) all eight counties suggested specific improvements to future products, primarily larger scale or more detail and fewer technical or more interpretive products; and (6) all eight counties received educational, advisory, and review services from USGS personnel. Seventeen selected examples of the application of SFBRS products to various county planning activities are discussed and illustrated. These examples include four planning studies, seven plans, and two ordinances. From the inventory and responses to the interviews, it is concluded that the counties in the Bay region are very familiar with, have made frequent use of, and will continue to use SFBRS products for a wide range of county planning activities. Suggestions to ensure more effective use of earth-science information in the future include: (1) monitoring emerging critical issues and analyzing new state and federal laws and regulations so as to better anticipate and respond to county earth-science information needs; (2) creating a users advisory committee to help identify critical issues and user needs; (3) providing engineering interpretations and land- and water-use capability ratings to make earth-science information more readily usable; (4) giving priority to areas impacted by development so as to husband staff resources; (5) providing earth-science information at the larger scale and greater detail commonly used and needed by counties; (6) releasing earth-science information earlier and according to a formal distribution pattern; and (7) providing educational, advisory, and review services in connection with any earth-science information designed for planners and decisionmakers.

Three-dimensional presentation of the earth and planets in classrooms and science centers with a spherical screen

NASA Astrophysics Data System (ADS)

Saito, A.; Tsugawa, T.; Odagi, Y.; Nishi, N.; Miyazaki, S.; Ichikawa, H.

2012-12-01

Educational programs have been developed for the earth and planetary science using a three-dimensional presentation system of the Earth and planets with a spherical screen. They have been used in classrooms of universities, high schools, elementary schools, and science centers. Two-dimensional map is a standard tool to present the data of the Earth and planets. However the distortion of the shape is inevitable especially for the map of wide areas. Three-dimensional presentation of the Earth, such as globes, is an only way to avoid this distortion. There are several projects to present the earth and planetary science results in three-dimension digitally, such as Science on a sphere (SOS) by NOAA, and Geo-cosmos by the National Museum of Emerging Science and Innovation (Miraikan), Japan. These projects are relatively large-scale in instruments and cost, and difficult to use in classrooms and small-scale science centers. Therefore we developed a portable, scalable and affordable system of the three-dimensional presentation of the Earth and planets, Dagik Earth. This system uses a spherical screen and a PC projector. Several educational programs have been developed using Dagik Earth under collaboration of the researchers of the earth and planetary science and science education, school teachers, and curators of science centers, and used in schools and museums in Japan, Taiwan and other countries. It helps learners to achieve the proper cognition of the shape and size of the phenomena on the Earth and planets. Current status and future development of the project will be introduced in the presentation.

Lagrange Point Missions: the Key to Next-Generation Integrated Earth Observations. DSCOVR Innovation

NASA Astrophysics Data System (ADS)

Valero, F. P. J.

2016-12-01

From L-1 DSCOVR is capable of new, unique observations potentially conducive to a deeper scientific understanding of the Earth sciences. At L-1 and L-2 the net gravitational pull of the Earth and Sun equals the centripetal force required to orbit the Sun with the same period as the Earth. Satellites at or near L-1 and L-2 keep the same position relative to the Sun and the Earth. DSCOVR does not orbit the Earth but the Sun in synchronism with Earth, acts like a planetoid (orbits the Sun in the ecliptic plane) while acquiring integrated plus spatially and time resolved scientific data as Earth rotates around its axis. Because of the planet's axial tilt relative to the ecliptic plane, the Polar Regions are visible during local summer from L-1 and local winter from L-2 (Fig. 1). DSCOVR's synoptic and continuous observations solve most of the temporal and spatial limitations associated with low Earth (LEO) and Geostationary (GEO) orbits. Two observatories, one at L-1 (daytime) and one at L-2 (nighttime), would acquire minute-by-minute climate quality data for essentially every point on Earth. The integration of L-1, L-2, LEO, and GEO satellites plus the Moon offers new scientific tools and enriched data sets for Earth sciences. Lagrange points observatories are key to next-generation integrated Earth observations. For example, DSCOVR at L-1 views the Earth plus the Moon (a reference) and simultaneously, at one time or another, all LEO and GEO satellites. The L-1 and L-2 satellites would be the link between the Moon, LEO and GEO satellites while providing the data needed to build an integrated Earth observational system. The above properties are the bases for DSCOVR's innovation and scientific approach that systematically observes climate drivers (radiation, aerosols, ozone, clouds, water vapor, vegetation) from L-1 in a way not possible but synergistic with other satellites. Next step: more capable L-1 plus L-2 satellites. The way of the future.

Lessons from NASA Applied Sciences Program: Success Factors in Applying Earth Science in Decision Making

NASA Astrophysics Data System (ADS)

Friedl, L. A.; Cox, L.

2008-12-01

The NASA Applied Sciences Program collaborates with organizations to discover and demonstrate applications of NASA Earth science research and technology to decision making. The desired outcome is for public and private organizations to use NASA Earth science products in innovative applications for sustained, operational uses to enhance their decisions. In addition, the program facilitates the end-user feedback to Earth science to improve products and demands for research. The Program thus serves as a bridge between Earth science research and technology and the applied organizations and end-users with management, policy, and business responsibilities. Since 2002, the Applied Sciences Program has sponsored over 115 applications-oriented projects to apply Earth observations and model products to decision making activities. Projects have spanned numerous topics - agriculture, air quality, water resources, disasters, public health, aviation, etc. The projects have involved government agencies, private companies, universities, non-governmental organizations, and foreign entities in multiple types of teaming arrangements. The paper will examine this set of applications projects and present specific examples of successful use of Earth science in decision making. The paper will discuss scientific, organizational, and management factors that contribute to or impede the integration of the Earth science research in policy and management. The paper will also present new methods the Applied Sciences Program plans to implement to improve linkages between science and end users.

New Age for Lunar Exploration

Taylor, G. J.; Martel, L. M. V.

2018-04-01

Lunar-focused research and plans to return to the lunar surface for science and exploration have reemerged since the Space Policy Directive-1 of December 11, 2017 amended the National Space Policy to include the following, "Lead an innovative and sustainable program of exploration with commercial and international partners to enable human expansion across the solar system and to bring back to Earth new knowledge and opportunities. Beginning with missions beyond low-Earth orbit, the United States will lead the return of humans to the Moon for long-term exploration and utilization, followed by human missions to Mars and other destinations." In response to this revision, NASA proposes a Lunar Exploration and Discovery Program in the U.S. fiscal year 2019 Budget Request. It supports NASA's interests in commercial and international partnerships in Low-Earth Orbit (LEO), long-term exploration in Cislunar space beyond LEO, and research and exploration conducted on the Moon to inform future crewed missions, even to destinations beyond the Moon. (Cislunar refers to the volume of space between LEO and the Moon's orbital distance.) The lunar campaign strengthens the integration of human and robotic activities on the lunar surface with NASA's science, technology, and exploration goals.

Perceived Barriers and Strategies to Effective Online Earth and Space Science Instruction

NASA Astrophysics Data System (ADS)

Pottinger, James E.

With the continual growth and demand of online courses, higher education institutions are attempting to meet the needs of today's learners by modifying and developing new student centered services and programs. As a result, faculty members are being forced into teaching online, including Earth and Space science faculty. Online Earth and Space science courses are different than typical online courses in that they need to incorporate an inquiry-based component to ensure students fully understand the course concepts and science principles in the Earth and Space sciences. Studies have addressed the barriers in other inquiry-based online science courses, including biology, physics, and chemistry. This holistic, multiple-case qualitative study investigated perceived barriers and strategies to effective online Earth and Space science instruction through in-depth interviews with six experienced post-secondary online science instructors. Data from this study was analyzed using a thematic analysis approach and revealed four common themes when teaching online Earth and Space science. A positive perception and philosophy of online teaching is essential, the instructor-student interaction is dynamic, course structure and design modification will occur, and online lab activities must make science operational and relevant. The findings in this study demonstrated that online Earth and Space science instructors need institutional support in the form of a strong faculty development program and support staff in order to be as effective as possible. From this study, instructors realize that the instructor-student relationship and course structure is paramount, especially when teaching online science with labs. A final understanding from this study was that online Earth and Space science lab activities must incorporate the use and application of scientific skills and knowledge. Recommendations for future research include (a) qualitative research conducted in specific areas within the Earth and Space sciences to determine if similar conclusions may be reached, (b) conduct a quantitative study looking at the available online technologies and their effectiveness in each area, and (c) utilize students that took online Earth and Space science classes and compare their perception of effectiveness to the instructor's perception of effectiveness in the online Earth and Space science classroom.

Understanding the Deep Earth: Slabs, Drips, Plumes and More - An On the Cutting Edge Workshop

NASA Astrophysics Data System (ADS)

Williams, M. L.; Mogk, D. W.; McDaris, J. R.

2010-12-01

Exciting new science is emerging from the study of the deep Earth using a variety of approaches: observational instrumentation (e.g. EarthScope’s USArray; IRIS), analysis of rocks (xenoliths, isotopic tracers), experimental methods (COMPRES facilities), and modeling (physical and computational, e.g. CIG program). New images and models of active faults, subducting plates, mantle drips, and rising plumes are spurring a new excitement about deep Earth processes and connections between Earth’s internal systems, the plate tectonic system, and the physiography of Earth’s surface. The integration of these lines of research presents unique opportunities and also challenges in geoscience education. How can we best teach about the architecture, composition, and processes of Earth where it is hidden from direct observation. How can we make deep Earth science relevant and meaningful to students across the geoscience curriculum? And how can we use the exciting new discoveries about Earth processes to attract new students into science? To explore the intersection of research and teaching about the deep Earth, a virtual workshop was convened in February 2010 for experts in deep Earth research and undergraduate geoscience education. The six-day workshop consisted of online plenary talks, large and small group discussions, asynchronous contributions using threaded listservs and web-based work spaces, as well as development and review of new classroom and laboratory activities. The workshop goals were to: 1) help participants stay current about data, tools, services, and research related to the deep earth, 2) address the "big science questions" related to deep earth (e.g. plumes, slabs, drips, post-perovskite, etc.) and explore exciting new scientific approaches, 3) to consider ways to effectively teach about "what can't be seen", at least not directly, and 4) develop and review classroom teaching activities for undergraduate education using these data, tools, services, and research results to facilitate teaching about the deep earth across the geoscience curriculum. Another goal of the workshop was to experiment with, and evaluate the effectiveness of, the virtual format. Although there are advantages to face-to-face workshops, the virtual format was remarkably effective. The interactive discussions during synchronous presentations were vibrant, and the virtual format allowed participants to introduce references, images and ideas in real-time. The virtual nature of the workshop allowed participation by those who are not able to attend a traditional workshop, with an added benefit that participants had direct access to all their research and teaching materials to share with the workshop. Some participants broadcast the workshop ‘live’ to their classes and many brought discussions directly from the presentation to the classroom. The workshop webpage includes the workshop program with links to recordings of all presentations, discussion summaries, a collection of recommended resources about deep Earth research, and collections of peer-reviewed instructional activities. http://serc.carleton.edu/NAGTWorkshops/deepearth/index.html

Seismic to­mography; theory and practice

USGS Publications Warehouse

Iver, H.M.; Hirahara, Kazuro

1993-01-01

Although highly theoretical and computer-orientated, seismic tomography has created spectacular images of anomolies within the Earth with dimensions of thousands of kilometers to few tens of meters. These images have enabled Earth scientists working on diverse areas to attack fundamental problems relating to the deep dynamical processes within our planet. Additionally, this technique is being used extensively to study the Earth's hazardous regions such as earthquake fault zones and volcanoes, as well as features beneficial to man such as oil or mineral-bearing structures. This book has been written by world experts and describes the theories, experimental and analytical procedures and results of applying seismic tomography from global to purely local scale. It represents the collective global perspective on the state of the art and focusses not only on the theoretical and practical aspects, but also on the uses for hydrocarbon, mineral and geothermal exploitation. Students and researchers in the Earth sciences, and research and exploration geophysicists should find this a useful, practical reference book for all aspects of their work.

MAESTRO: Mathematics and Earth Science Teachers' Resource Organization

NASA Astrophysics Data System (ADS)

Courtier, A. M.; Pyle, E. J.; Fichter, L.; Lucas, S.; Jackson, A.

2013-12-01

The Mathematics and Earth Science Teachers' Resource Organization (MAESTRO) partnership between James Madison University and Harrisonburg City and Page County Public Schools, funded through NSF-GEO. The partnership aims to transform mathematics and Earth science instruction in middle and high schools by developing an integrated mathematics and Earth systems science approach to instruction. This curricular integration is intended to enhance the mathematical skills and confidence of students through concrete, Earth systems-based examples, while increasing the relevance and rigor of Earth science instruction via quantification and mathematical modeling of Earth system phenomena. MAESTRO draws heavily from the Earth Science Literacy Initiative (2009) and is informed by criterion-level standardized test performance data in both mathematics and Earth science. The project has involved two summer professional development workshops, academic year Lesson Study (structured teacher observation and reflection), and will incorporate site-based case studies with direct student involvement. Participating teachers include Grade 6 Science and Mathematics teachers, and Grade 9 Earth Science and Algebra teachers. It is anticipated that the proposed integration across grade bands will first strengthen students' interests in mathematics and science (a problem in middle school) and subsequently reinforce the relevance of mathematics and other sciences (a problem in high school), both in support of Earth systems literacy. MAESTRO's approach to the integration of math and science focuses on using box models to emphasize the interconnections among the geo-, atmo-, bio-, and hydrospheres, and demonstrates the positive and negative feedback processes that connect their mutual evolution. Within this framework we explore specific relationships that can be described both qualitatively and mathematically, using mathematical operations appropriate for each grade level. Site-based case studies, developed in collaboration between teachers and JMU faculty members, provide a tangible, relevant setting in which students can apply and understand mathematical applications and scientific processes related to evolving Earth systems. Initial results from student questionnaires and teacher focus groups suggest that the anticipated impacts of MAESTRO on students are being realized, including increased valuing of mathematics and Earth science in society and transfer between mathematics and science courses. As a high percentage of students in the MAESTRO schools are of low socio-economic status, they also face the prospect of becoming first-generation college students, hopefully considering STEM academic pathways. MAESTRO will drive the development of challenging and engaging instruction designed to draw a larger pool of students into STEM career pathways.

Three-dimensional presentation of the earth and space science data in collaboration among schools, science museums and scientists

NASA Astrophysics Data System (ADS)

Saito, Akinori; Tsugawa, Takuya

Three-dimensional presentation of the earth and space science data is a best tool to show the scientific data of the earth and space. It can display the correct shape on the Earth while any two-dimensional maps distort shapes. Furthermore it helps audience to understand the scale size and phenomena of the earth and planets in an intuitive way. There are several projects of the 3-D presentation of the Earth, such as Science on a Sphere (SOS) by NOAA, and Geo-cosmos by Miraikan, Japan. We are developing a simple, portable and affordable 3-D presentation system, called Dagik Earth. It uses a spherical or hemispherical screen to project data and images using normal PC and PC projector. The minimum size is 8cm and the largest size is 8m in diameter. The Dagik Earth project has developed the software of the 3-D projection in collaboration with scientists, and provides the software to the science museums and school teachers. Because the same system can be used in museums and schools, several science museums play a roll of hub for the school teachers' training on the earth and planetary science class with Dagik Earth. International collaboration with Taiwan, Thailand, and other countries is in progress. In the presentation, we introduce the system of Dagik Earth and the activities using it in the collaboration among schools, science centers, universities and research institutes.

The NSF-funded EarthCube Integration and Test Environment (ECITE) prototype was proposed as a 2015 Integrated Activities project and resulted in the prototyping of an EarthCube federated cloud environment and the Integration and Testing Framework. The ECITE team has worked with EarthCube science and technology governance committees to define the types of integration, testing and evaluation necessary to achieve and demonstrate interoperability and functionality that benefit and support the objectives of the EarthCube cyber-infrastructure. The scope of ECITE also includes reaching beyond NSF and EarthCube to work with the broader Earth science community, such as the Earth Science Information Partners (ESIP) to incorporate lessons learned from other testbed activities, and ultimately provide broader community benefits. This presentation will discuss evolving ECITE ideas for a science-driven workbench that will start with documented science use cases, map the use cases to solution scenarios that identify the available technology and data resources that match the use case, the generation of solution workflows and test plans, the testing and evaluation of the solutions in a cloud environment, and finally the documentation of identified technology and data gaps that will assist with driving the development of additional EarthCube resources.

Earth Science Informatics - Overview

Over the last 10-15 years, significant advances have been made in information management, there are an increasing number of individuals entering the field of information management as it applies to Geoscience and Remote Sensing data, and the field of informatics has come to its own. Informatics is the science and technology of applying computers and computational methods to the systematic analysis, management, interchange, and representation of science data, information, and knowledge. Informatics also includes the use of computers and computational methods to support decision making and applications. Earth Science Informatics (ESI, a.k.a. geoinformatics) is the application of informatics in the Earth science domain. ESI is a rapidly developing discipline integrating computer science, information science, and Earth science. Major national and international research and infrastructure projects in ESI have been carried out or are on-going. Notable among these are: the Global Earth Observation System of Systems (GEOSS), the European Commissions INSPIRE, the U.S. NSDI and Geospatial One-Stop, the NASA EOSDIS, and the NSF DataONE, EarthCube and Cyberinfrastructure for Geoinformatics. More than 18 departments and agencies in the U.S. federal government have been active in Earth science informatics. All major space agencies in the world, have been involved in ESI research and application activities. In the United States, the Federation of Earth Science Information Partners (ESIP), whose membership includes over 180 organizations (government, academic and commercial) dedicated to managing, delivering and applying Earth science data, has been working on many ESI topics since 1998. The Committee on Earth Observation Satellites (CEOS)s Working Group on Information Systems and Services (WGISS) has been actively coordinating the ESI activities among the space agencies.

The Transforming Earth System Science Education (TESSE) project, a partnership between faculty at the University of New Hampshire, Pennsylvania State University, Elizabeth City State University and Dillard University, is designed to enrich the professional development of in-service and pre-service Earth science teachers. One goal of this effort is to help teachers use an inquiry-based approach to teaching Earth system science in their classrooms. As a part of the TESSE project, 42 pre-service and in-service teachers participated in an intensive two-week summer institute at UNH taught by Earth scientists and science educators from TESSE partnership institutions. The institute included instruction about a range of Earth science system topics as well as an introduction to teaching Earth science using an inquiry-based approach. In addition to providing teachers with information about inquiry-based science teaching in the form of sample lesson plans and opportunities to revise traditional lessons and laboratory exercises to make them more inquiry-based, TESSE instructors modeled an inquiry- based approach in their own teaching as much as possible. By the end of the Institute participants had developed lesson plans, units, or year-long course overviews in which they were expected to explain the ways in which they would include an inquiry-based approach in their Earth science teaching over the course of the school year. As a part of the project, graduate fellows (graduate students in the earth sciences) will work with classroom teachers during the academic year to support their implementation of these plans as well as to assist them in developing a more comprehensive inquiry-based approach in the classroom.

Earth science data products and services are being used by representatives of various science and social science disciplines, by planning and decision-making professionals, by educators and learners ranging from primary through graduate and informal education, and by the general public. The diversity of users and uses of Earth science data is gratifying and offers new challenges for enabling the usability of these data by audiences with various purposes and levels of expertise. Users and other stakeholders need capabilities to efficiently find, explore, select, and determine the applicability and suitability of data products and services to meet their objectives and information needs. Similarly, they need to be able to understand the limitations of Earth science data, which can be complex, especially when considering combined or simultaneous use of multiple data products and services. Quality control efforts of stakeholders, throughout the data lifecycle, can contribute to the usability of Earth science data to meet the needs of diverse users. Such stakeholders include study design teams, data producers, data managers and curators, archives, systems professionals, data distributors, end-users, intermediaries, sponsoring organizations, hosting institutions, and others. Opportunities for engaging stakeholders to review, describe, and improve the quality of Earth science data products and services throughout the data lifecycle are identified and discussed. Insight is shared from the development of guidelines for implementing the Group on Earth Observations (GEO) Data Management Principles, the recommendations from the Earth Science Data System Working Group (ESDSWG) on Data Quality, and the efforts of the Information Quality Cluster of the Federation of Earth Science Information Partners (ESIP). Examples and outcomes from quality control efforts of data facilities, such as scientific data centers, that contribute to the usability of Earth science data also are offered.

What to do when the Universities reject High School Earth Science

Van Norden, W.

2011-12-01

It is hard to imagine a state of the union more affected by Earth processes than the state of California. However, the University of California actively discourages High School students from taking Earth Science courses. For admission into the University of California students are required to take at least 2 years of courses that offer a fundamental knowledge in at least two of these three foundational subjects: biology, chemistry, and physics. Earth Science courses simply don't qualify as laboratory science courses. The UC Admissions will sometimes make an exception for an Earth Science course only if it is shown to contain a large component of biology, chemistry and physics topics. Since students don't get credit for admission for taking Earth Science, High Schools are quick to drop Earth Science courses for their college-bound students. A group of teachers and University professors have been working to reverse this policy by creating a rigorous capstone Earth Science course that clearly merits laboratory status. Getting this course accepted by the University of California is well on its way, but getting the course into the High Schools will take a lot of work and probably some extra funding.

The Goddard Space Flight Center (GSFC) is one of the largest Earth Science research-based institutions in the nation. Along with the research comes a dedicated group of people who are tasked with developing Earth science research-based education and public outreach materials to reach the broadest possible range of audiences. The GSFC Earth science education community makes use of a wide variety of platforms in order to reach their goals of communicating science. These platforms include using social media networking such as Twitter and Facebook, as well as geo-spatial tools such as MY NASA DATA, NASA World Wind, NEO, and Google Earth. Using a wide variety of platforms serves the dual purposes of promoting NASA Earth Science research and making authentic data available to educational communities that otherwise might not otherwise be granted access. Making data available to education communities promotes scientific literacy through the investigation of scientific phenomena using the same data that is used by the scientific community. Data from several NASA missions will be used to demonstrate the ways in which Earth science data are made available for the education community.

The space vehicle for Gravity Probe B (GP-B) arrives at the launch site at Vandenburg Air Force Base. GP-B is the relativity experiment being developed at Stanford University to test two extraordinary predictions of Albert Einstein's general theory of relativity. The experiment will measure, very precisely, the expected tiny changes in the direction of the spin axes of four gyroscopes contained in an Earth-orbiting satellite at a 400-mile altitude. So free are the gyroscopes from disturbance that they will provide an almost perfect space-time reference system. They will measure how space and time are very slightly warped by the presence of the Earth, and, more profoundly, how the Earth's rotation very slightly drags space-time around with it. These effects, though small for the Earth, have far-reaching implications for the nature of matter and the structure of the Universe. GP-B is among the most thoroughly researched programs ever undertaken by NASA. This is the story of a scientific quest in which physicists and engineers have collaborated closely over many years. Inspired by their quest, they have invented a whole range of technologies that are already enlivening other branches of science and engineering. Scheduled for launch in 2003 and managed for NASA by the Marshall Space Flight Center, development of the GP-B is the responsibility of Stanford University, with major subcontractor Lockheed Martin Corporation.

The Earth's Critical Zone (CZ) is the terrestrial portion of the continents ranging from the top of the vegetative canopy down through soil and bedrock to the lowest extent of freely circulating groundwater. The primary objective of CZ science is to characterize and understand how the reciprocal interactions among rock, soil, water, air and terrestrial organisms influence the Earth as a habitable environment. Thus it is a highly multidisciplinary science that incorporates the biological, hydrological, geological and atmospheric sciences and provides a holistic approach to teaching Earth system science. Here we share highlights from a full-semester university curriculum that introduces upper-division Environmental Science, Geology, Hydrology and Earth Science students to CZ science. We emphasize how a CZ framework is appropriate to teach concepts across the scientific disciplines, concepts of sustainability, and how CZ science serves as a useful approach to solving humanities' grand challenges.

In Physics Department Universitas Negeri Semarang, Earth and Space Science subject is included in the curriculum of the third year of physics education students. There are various models of teaching earth and space science subject such as textbook method, lecturer, demonstrations, study tours, problem-solving method, etc. Lectures method is the most commonly used of teaching earth and space science subject. The disadvantage of this method is the lack of two ways interaction between lecturers and students. This research used small group discussion as a teaching method in Earth and Space science. The purpose of this study is to identify the conditions under which an efficient discussion may be initiated and maintained while students are investigating properties of earth and space science subjects. The results of this research show that there is an increase in student’s understanding of earth and space science subject proven through the evaluation results. In addition, during the learning process, student’s activeness also increase.

Citations and acknowledgements in scientific journals can be an indicator of the role an organization has on the research of that field. Since its formation and incorporation in May 1984, the IRIS Consortium (Incorporated Research Institutions for Seismology) is mentioned more and more as a valuable source of data, instruments and programs in the literature of earth sciences. As a large organization with more than 100 member domestic institutes and about 40 international affiliates, obviously IRIS has a direct impact on the earth sciences through all its programs, projects, workshops, symposia, and news¬letters and as a lively forum for exchanging ideas. In order to maintain support from National Science Foundation (NSF) and the research community, it is important to document the continued use of IRIS facilities in basic research programs. IRIS maintains a database of articles that are based on the use of IRIS facilities or which reference use of IRIS data and resources. Articles in this database have been either been provided to IRIS by the authors or selected through an annual search of a number of prominent journals. A text version of the full bibliographic database is available on the IRIS website and a version in EndNote format is also provided. To provide a more complete bibliography and a consistent evaluation of temporal tends in publications, a special annual search began in 2000 which focused on a subset of key seismology and Earth science journals: Bulletin of Seismological Society of America, Journal of Geophysical Research, Seismological Research Letters, Geophysical Research Letters, Earth and Planetary Science Letters, Physics of the Earth and Planetary Interiors, Tectonophysics, Geophysical Journal International, Nature, Science, Geology and EOS. Using different search engines as Scirus, ScienceDirect, GeoRef, OCLC First Search, EASI Search, NASA Abstract Service etc. for online journals and publishers' databases, we searched for key words (IRIS, GSN, DMS, PASSCAL, USArray etc) in titles, abstracts and text. Most of the selections found by this method were confirmed by reading through online texts or original journals. This bibliography of peer-reviewed articles (excluding abstracts) identified in these key journals for 2000-2011 includes approximately 1800 entries. As for American Geophysical Union (AGU) transaction, the bibliography of IRIS-related abstracts for the abovementioned period includes approximately 1400 abstracts. This study is a clear indicator of making intensive use by the seismological community of the resources that IRIS provides and of the paramount importance this organization has in advancement of seismological research worldwide.

Earth and Space Science may be the neglected child in the family of high school sciences. In this session, we examine the strategies that Anne Arundel County Public Schools and NASA Goddard Space Flight Center used to develop a dynamic and highly engaging program which follows the vision of the National Science Education Standards, is grounded in key concepts of NASA's Earth Science Directorate, and allows students to examine and apply the current research of NASA scientists. Find out why Earth/Space Systems Science seems to have usurped biology and has made students, principals, and teachers clamor for similar instructional practices in what is traditionally thought of as the "glamorous" course.

Microbial and Chemical Enhancement of In-Situ Carbon Mineralization in Geological Formation

Matter, J.; Chandran, K.

2013-05-31

Predictions of global energy usage suggest a continued increase in carbon emissions and rising concentrations of CO{sub 2} in the atmosphere unless major changes are made to the way energy is produced and used. Various carbon capture and storage (CCS) technologies are currently being developed, but unfortunately little is known regarding the fundamental characteristics of CO{sub 2}-mineral reactions to allow a viable in-situ carbon mineralization that would provide the most permanent and safe storage of geologically-injected CO{sub 2}. The ultimate goal of this research project was to develop a microbial and chemical enhancement scheme for in-situ carbon mineralization in geologicmore » formations in order to achieve long-term stability of injected CO{sub 2}. Thermodynamic and kinetic studies of CO{sub 2}-mineral-brine systems were systematically performed to develop the in-situ mineral carbonation process that utilizes organic acids produced by a microbial reactor. The major participants in the project are three faculty members and their graduate and undergraduate students at the School of Engineering and Applied Science and at the Lamont-Doherty Earth Observatory at Columbia University: Alissa Park in Earth and Environmental Engineering & Chemical Engineering (PI), Juerg Matter in Earth and Environmental Science (Co-PI), and Kartik Chandran in Earth and Environmental Engineering (Co-PI). Two graduate students, Huangjing Zhao and Edris Taher, were trained as a part of this project as well as a number of graduate students and undergraduate students who participated part-time. Edris Taher received his MS degree in 2012 and Huangjing Zhao will defend his PhD on Jan. 15th, 2014. The interdisciplinary training provided by this project was valuable to those students who are entering into the workforce in the United States. Furthermore, the findings from this study were and will be published in referred journals to disseminate the results. The list of the papers is given at the end of the report for reference.« less

Burrell, S.

2012-12-01

Given low course enrollment in geoscience courses, retention in undergraduate geoscience courses, and granting of BA and advanced degrees in the Earth sciences an effective strategy to increase participation in this field is necessary. In response, as K-12 education is a conduit to college education and the future workforce, Earth science education at the K-12 level was targeted with the development of teacher professional development around Earth system science, inquiry and problem-based learning. An NSF, NOAA and NASA funded effort through the Institute for Global Environmental Strategies led to the development of the Earth System Science Educational Alliance (ESSEA) and dissemination of interdisciplinary Earth science content modules accessible to the public and educators. These modules formed the basis for two teacher workshops, two graduate level courses for in-service teachers and two university course for undergraduate teacher candidates. Data from all three models will be presented with emphasis on the teacher workshop. Essential components of the workshop model include: teaching and modeling Earth system science analysis; teacher development of interdisciplinary, problem-based academic units for implementation in the classroom; teacher collaboration; daily workshop evaluations; classroom observations; follow-up collaborative meetings/think tanks; and the building of an on-line professional community for continued communication and exchange of best practices. Preliminary data indicate increased understanding of Earth system science, proficiency with Earth system science analysis, and renewed interest in innovative delivery of content amongst teachers. Teacher-participants reported increased student engagement in learning with the implementation of problem-based investigations in Earth science and Earth system science thinking in the classroom, however, increased enthusiasm of the teacher acted as a contributing factor. Teacher feedback on open-ended questionnaires about impact on students identify higher order thinking, critical evaluation of quantitative and qualitative information, cooperative learning, and engagement in STEM content through inquiry as core competencies of this educational method. This presentation will describe the program model and results from internal evaluation.

Graham Ryder died in January 2002 at the age of 53. He was a Staff Scientist at the Lunar and Planetary Science Institute in Houston, TX for most of his professional life, studying lunar petrology and planetary impacts. For many years he was the senior editor of the Proceedings of the Lunar and Planetary Science Conference, and he was the senior editor of Geological Society of America Special Paper 307, The Cretaceous-Tertiary Event and Other Catastrophes in Earth History. He was the major advocate for the 3.8 Ga lunar impact cataclysm and was just beginning to publish on correlations of the early lunar impact record to that of the other inner planets at the time of his death. Graham's abstract to the Rubey Colloquium was never presented. Although Graham made many of the points in this abstract to lunar science audiences, he certainly would have wanted these views to be shared with the Astrobiology community. We have taken the liberty of publishing this abstract with the Rubey proceedings, with only a few minor revisions to include reference to some recently published papers. These revisions were recommended by Gary R. Byerly, who reviewed this abstract for publication.

A Mars Sample Return mission is the highest priority science mission for the next decade recommended by the recent Decadal Survey of Planetary Science, the key community input process that guides NASAs science missions. A feasibility study was conducted of a potentially simple and low cost approach to Mars Sample Return mission enabled by the use of developing commercial capabilities. Previous studies of MSR have shown that landing an all up sample return mission with a high mass capacity lander is a cost effective approach. The approach proposed is the use of an emerging commercially available capsule to land the launch vehicle system that would return samples to Earth. This paper describes the mission and technology requirements impact on the launch vehicle system design, referred to as the Mars Ascent Vehicle (MAV).

Earth science interpretation is more than giving your audience facts and figures. It is about relate Earth sciences to something within the personality or experience of your audience. It is about revelation based on information rather than just give away information per se. And: The chief aim of interpretation is not instruction but provocation. A great environment for Earth and Space science communication is a museum. Whether it is an art gallery, a technology exhibition or a national park's visitor center doesn't matter. Everywhere, Earth science interpretation is possible and sometimes even more successful in unsuspected locations than in natural history museums. Earth and Space sciences just started to use the potential which lies within museum environments. A historic view on Earth sciences and natural hazard research can be given in art galleries. The technology used in research can be showcased and - sometimes - even tested in science centers and technology museums. National Parks provide the best opportunity to actually experience the dynamic planet Earth live. Furthermore, museums do offer a great venue for educational programs. Just recently, the German Research and Development Program GEOTECHNOLOGIEN, together with the Germany's Geounion and the Institute for Advanced Sustainable Studies initiated a network of research institutions and museums called GeoED. Within this network, scientists and educationists as well as teachers will find an environment to create and enhance educational programs in Earth and Space science. Therefore, museums do not only provide the venue, but also the frame for sustainable Earth and Space science interpretation. This talk aims towards giving an insight view on how to conduct interpretive programs in museums, how to utilize the treasures and possibilities provided by museums and national parks and to encourage scientists to go to these places for face-to-face Earth science interpretation.

Remote Sensing data generation by NASA to study Earth s geophysical processes was initiated in 1960 with the launch of the first Television Infrared Observation Satellite Program (TIROS), to develop a meteorological satellite information system. What would be deemed as a primitive data set by today s standards, early Earth science missions were the foundation upon which today s remote sensing instruments have built their scientific success, and tomorrow s instruments will yield science not yet imagined. NASA Scientific Data Stewardship requirements have been documented to ensure the long term preservation and usability of remote sensing science data. In recent years, the Federation of Earth Science Information Partners and NASA s Earth Science Data System Working Groups have organized committees that specifically examine standards, processes, and ontologies that can best be employed for the preservation of remote sensing data, supporting documentation, and data provenance information. This presentation describes the activities, issues, and implementations, guided by the NASA Earth Science Data Preservation Content Specification (423-SPEC-001), for preserving instrument characteristics, and data processing and science information generated for 20 Earth science instruments, spanning 40 years of geophysical measurements, at the NASA s Goddard Earth Sciences Data and Information Services Center (GES DISC). In addition, unanticipated preservation/implementation questions and issues in the implementation process are presented.

Earth and planetary scientists are united by their need for accurate maps. Without them, features studied have no reference point, attempts to understand how our and other planets evolved have no context, and missions flown to other planets lack purpose. "Making maps out of data is critical to further progress in our fields," explained Randolph Kirk of the U.S. Geological Survey's (USGS) Astrogeology Science Center, based in Flagstaff, Ariz. "Building maps helps other people find what's out there."

The IDES (Increasing Diversity in Earth Sciences) Program is the first partnership of its kind in the state of Oregon targeted at broadening participation in the Earth Science enterprise. Funded by the National Science Foundation Opportunities to Enhance Diversity in the Geosciences program (NSF-OEDG), this partnership involves community colleges, a research university with major strengths in Earth Science research and education and an institutionalized commitment to enhancing diversity, state and federal agencies, centers of informal education, and the Oregon Space Grant Consortium, IDES has two integrated goals: 1) to increase the number of students from under-represented groups who pursue careers in Earth Science research and education, and 2) to strengthen the understanding of Earth Sciences and their relevance to society among broad and diverse segments of the population. Built around the best practices of tiered mentoring, interactive student cohort, research and education internships, and financial support, this 4-year program recruits 10 to 12 students (mainly rising juniors) each year from science majors at Oregon State University and five Oregon community colleges. The program is reaching its goals by: a) training participants in the application of geospatial to Earth Science problems of personal relevance b) immersing participants in a two-year mentored research project that involves summer internships with academic units, state and federal agencies, and centers for informal education in Oregon. c) exposing, educating, and involving participants in the breadth of Earth Science careers through contact with Earth Science professionals through mentors, a professional internship, and a learning community that includes a speaker series. d) instilling an understanding of context and relevance of the Earth Science Enterprise to the participants, their families, their communities, and the general public. We report on the first two years of this program during which 20 participants have been involved and significant feedback has been received.

2016-04-01

This study aimed to investigate the perception of earth system thinking of science gifted students in future problem solving (FPS) in relation to climate changes. In order to this study, the research problem associated with climate changes was developed through a literature review. The thirty seven science gifted students participated in lessons. The ideas in problem solving process of science gifted students were analyzed using the semantic network analysis method. The results are as follows. In the problem solving processes, science gifted students are ''changes of the sunlight by water layer'', ''changes of the Earth''s temperature'', ''changes of the air pressure'', '' change of the wind and weather''were represented in order. On other hand, regard to earth system thinking for climate changes, while science gifted students were used sub components related to atmospheres frequently, they were used sub components related to biosphere, geosphere, and hydrosphere a little. But, the analytical results of the structural relationship between the sub components related to earth system, they were recognised that biosphere, geosphere, and hydrosphere used very important in network structures. In conclusion, science gifted students were understood well that components of the earth system are influencing each other.

Storytelling in Earth sciences: The eight basic plots

NASA Astrophysics Data System (ADS)

Phillips, Jonathan

2012-11-01

Reporting results and promoting ideas in science in general, and Earth science in particular, is treated here as storytelling. Just as in literature and drama, storytelling in Earth science is characterized by a small number of basic plots. Though the list is not exhaustive, and acknowledging that multiple or hybrid plots and subplots are possible in a single piece, eight standard plots are identified, and examples provided: cause-and-effect, genesis, emergence, destruction, metamorphosis, convergence, divergence, and oscillation. The plots of Earth science stories are not those of literary traditions, nor those of persuasion or moral philosophy, and deserve separate consideration. Earth science plots do not conform those of storytelling more generally, implying that Earth scientists may have fundamentally different motivations than other storytellers, and that the basic plots of Earth Science derive from the characteristics and behaviors of Earth systems. In some cases preference or affinity to different plots results in fundamentally different interpretations and conclusions of the same evidence. In other situations exploration of additional plots could help resolve scientific controversies. Thus explicit acknowledgement of plots can yield direct scientific benefits. Consideration of plots and storytelling devices may also assist in the interpretation of published work, and can help scientists improve their own storytelling.

The Computational Science Education Reference Desk: A tool for increasing inquiry based learning in the science classroom

Joiner, D. A.; Stevenson, D. E.; Panoff, R. M.

2000-12-01

The Computational Science Reference Desk is an online tool designed to provide educators in math, physics, astronomy, biology, chemistry, and engineering with information on how to use computational science to enhance inquiry based learning in the undergraduate and pre college classroom. The Reference Desk features a showcase of original content exploration activities, including lesson plans and background materials; a catalog of websites which contain models, lesson plans, software, and instructional resources; and a forum to allow educators to communicate their ideas. Many of the recent advances in astronomy rely on the use of computer simulation, and tools are being developed by CSERD to allow students to experiment with some of the models that have guided scientific discovery. One of these models allows students to study how scientists use spectral information to determine the makeup of the interstellar medium by modeling the interstellar extinction curve using spherical grains of silicate, amorphous carbon, or graphite. Students can directly compare their model to the average interstellar extinction curve, and experiment with how small changes in their model alter the shape of the interstellar extinction curve. A simpler model allows students to visualize spatial relationships between the Earth, Moon, and Sun to understand the cause of the phases of the moon. A report on the usefulness of these models in two classes, the Computational Astrophysics workshop at The Shodor Education Foundation and the Conceptual Astronomy class at the University of North Carolina at Greensboro, will be presented.

The Next Great Science

NASA Astrophysics Data System (ADS)

Hodges, K. V.

2007-12-01

Earth science --- when defined as the study of all biological, chemical, and physical processes that interact to define the behavior of the Earth system --- has direct societal relevance equal to or greater than that any other branch of science. However, "geology", "geoscience", and "Earth science" departments are contracting at many universities and even disappearing at some. This irony speaks volumes about the limitations of the traditional university structure that partitions educational and research programs into specific disciplines, each housed in its own department. Programs that transcend disciplinary boundaries are difficult to fit into the traditional structure and are thus highly vulnerable to threats such as chronic underfunding by university administrations, low enrollments in more advanced subjects, and being largely forgotten during capital campaigns. Dramatic improvements in this situation will require a different way of thinking about earth science programs by university administrations. As Earth scientists, our goal must not be to protect "traditional" geology departments, but rather to achieve a sustainable programmatic future for broader academic programs that focus on Earth evolution from past, present, and future perspectives. The first step toward meeting this goal must be to promote a more holistic definition of Earth science that includes modes of inquiry more commonly found in engineering and social science departments. We must think of Earth science as a meta-discipline that includes core components of physics, geology, chemistry, biology, and the emerging science of complexity. We must recognize that new technologies play an increasingly important role in our ability to monitor global environmental change, and thus our educational programs must include basic training in the modes of analysis employed by engineers as well as those employed by scientists. One of the most important lessons we can learn from the engineering community is the value of systems-level thinking, and it makes good sense to make this the essential mantra of Earth science undergraduate and graduate programs of the future. We must emphasize that Earth science plays a central role in understanding processes that have shaped our planet since the origin of our species, processes that have thus influenced the rise and fall of human societies. By studying the co-evolution of Earth and human societies, we lay a critical part of the foundation for future environmental policymaking. If we can make this point persuasively, Earth science might just be the "next great science".

Project ALERT: Forging New Partnerships to Improve Earth System Science Education for Pre-Service and In-Service Teachers

2002-05-01

Project ALERT (Augmented Learning Environment and Renewable Teaching) was founded in 1998, with funding from NASA and the California State University (CSU), to improve earth system science education for pre-service teachers. Project ALERT has formed linkages between ten campuses of the CSU, which prepares about 60 percent of California's teachers, and two NASA centers, Ames Research Center and the Jet Propulsion Laboratory. ALERT has also fostered alliances between earth science and science education faculty. The combined expertise of Project ALERT's diverse partners has led to a wide array of activities and products, including: 1) incorporation in university classrooms of NASA-developed imagery, data, and educational resources; 2) creation and/or enhancement of several courses that bring earth systems science to pre-service teachers; 3) fellowships for CSU faculty to participate in collaborative research and education projects at the NASA Centers; 4) development of teaching modules on such varied topics as volcanoes, landslides, and paleoclimate; and 5) a central web site that highlights resources for teaching introductory Earth system science. An outgrowth of Project ALERT is the increased interest on the part of CSU earth scientists in education issues. This has catalyzed their participation in other projects, including NASA's Project NOVA, Earth System Science Education Alliance, and Sun-Earth Connection Education Forum, the Digital Library for Earth System Science Education, and the California Science Project. Project ALERT has also expanded to provide professional development opportunities for in-service teachers, as exemplified by its support of the Bay Area Earth Science Institute (BAESI) at San Jose State University. Each year, BAESI offers 10-15 full-day workshops that supply teachers and teachers-to-be with a blend of science concepts and classroom activities, free instructional materials, and the opportunity to earn inexpensive university credit. These workshops have been enriched by the incorporation of earth and space science information and curricular materials from NASA. In addition, visits to Ames Research Center have given BAESI participants an opportunity to explore the Educator Resource Center, learn about NASA's programs for teachers and students, and experience presentations by NASA scientists engaged in cutting edge research about the earth system. Project ALERT demonstrates the power of a state-based partnership that unites scientists and educators with diverse perspectives and strengths in a synergistic effort to improve science education.

Contextualizing Earth Science Professional Development Courses for Geoscience Teachers in Boston

Chen, R. F.; Pelletier, P.; Dorsen, J.; Douglas, E. M.; Pringle, M. S.; Karp, J.

2009-12-01

Inquiry-based, hands-on, graduate content courses have been developed specifically for Boston Public School middle school teachers of Earth Science. Earth Science I: Weather and Water and Earth Science II: The Solid Earth--Earth History and Planetary Systems have been taught a total of seven times to over 120 teachers. Several key attributes to these successful courses have been identified, including co-instruction by a university professor and a high school and a middle school teacher that are familiar with the Boston curriculum, use of hands-on activities that are closed related to those used in the Boston curriculum, pre- and post-course local field trips, and identification of key learning objectives for each day. This model of professional development was developed over several years in all disciplines (Earth Science, Physics, Biology, Chemistry) by the Boston Science Partnership (BSP), an NSF-funded Math Science Partnership program. One of the core strategies of the BSP is these Contextualized Content Courses (CCC), graduate level, lab-based courses taught at either UMass Boston or Northeastern University during summer intensive or semester formats. Two of the eleven courses developed under the grant are Earth Science I & II. This presentation shares the model of the CCC, the impact on teacher participants, the value of these courses for the professor, and lessons learned for successful professional development. Findings about the courses’ impact and effectiveness come from our external evaluation by the Program Evaluation Research Group (PERG). The combination of content and modeling good instructional practices have many positive outcomes for teachers, including increased self-efficacy in science understanding and teaching, positive impacts on student achievement, and teacher shifts from more traditional, more lecture-based instructional models to more inquiry approaches. STEM faculty members become involved in science education and learn and practice new instructional strategies. The teacher co-instructors hold leadership roles for their peers and gain university teaching experience. The participants have a course that is content rich and tailored for their needs in the classroom. Earth scientists develop a “broader impact” for their science by increasing climate and earth science literacy for teachers who, in turn, reach 100s to 1000s of students every year, possibly stimulating interest for students becoming future earth scientists, but at the very least, increasing the public appreciation for earth science.

ACCESS Earth is an intensive summer institute for high school students with disabilities and their teachers that is designed to encourage students with disabilities to consider careers in earth system science. Participants study earth system science concepts at a Maine coastal estuary, using Geographic Information Systems, remote sensing, and field observations to evaluate the impacts of climate change, sea level rise, and development on coastal systems. Teachers, students, and scientists work together to adapt field and laboratory activities for persons with disabilities, including those with mobility and visual impairments. Other sessions include demonstrations of assistive technology, career discussions, and opportunities for students to meet with successful scientists with disabilities from throughout the U.S. The summer institute is one of several programs in development at the University of Southern Maine to address the problem of underrepresentation of people with disabilities in the earth sciences. Other projects include a mentoring program for high school students, a web-based clearinghouse of resources for teaching earth sciences to students with disabilities, and guidebooks for adaptation of popular published earth system science curricula for disabled learners.

Issue-centered Earth Science undergraduate instruction in U.S. colleges and universities

NASA Astrophysics Data System (ADS)

Liddicoat, J. C.

2011-12-01

Semester-long introductory courses in Earth Science at U.S. colleges and universities often contain astronomy, meteorology, oceanography, and geology taught as single entities. My experience teaching Earth Science that way and using a trade Earth Science textbook results in cursory knowledge and poor retention of each topic area. This seems to be especially true for liberal arts students who take Earth Science to satisfy a distribution requirement in the sciences. Instead, my method of teaching Earth Science at the State University of New York is to use two books that together explore consequences of global warming caused by the combustion of fossil fuels by humans. In this way, students who do not intend to major in science are given in-depth information about how and why this challenge to the well-being of life on Earth in the present century and beyond must be addressed in a thoughtful way. The books, Tyler Volk's CO2 Rising - The World's Greatest Environmental Challenge and James Edinger's Watching for the Wind, are inexpensive paperbacks that the students read in their entirety. Besides supplemental information I provide in the lectures, students have weekly examinations that are narrative in form, and there are written assignments for exhibits at science and other museums in NYC that complement some of the topics. The benefit of teaching Earth Science in this non-traditional way is that students seem more interested in the subject because it is relevant to everyday experience and news accounts about a serious global science problem for which an informed public must take a positive role to solve.

Building on NASA's investment in the measurement of crustal deformation from continuous GPS, we are developing and implementing a Science Data System (SDS) that will provide mature, long-term Earth Science Data Records (ESDR's). This effort supports NASA's Earth Surface and Interiors (ESI) focus area and provide NASA's component to the EarthScope PBO. This multi-year development is sponsored by NASA's Making Earth System data records for Use in Research Environments (MEaSUREs) program. The SDS integrates the generation of ESDRs with data analysis and exploration, product generation, and modeling tools based on daily GPS data that include GPS networks in western North America and a component of NASA's Global GPS Network (GGN) for terrestrial reference frame definition. The system is expandable to multiple regional and global networks. The SDS builds upon mature data production, exploration, and analysis algorithms developed under NASA's REASoN, ACCESS, and SENH programs. This SDS provides access to positions, time series, velocity fields, and strain measurements derived from continuous GPS data obtained at tracking stations in both the Plate Boundary Observatory and other regional Western North America GPS networks, dating back to 1995. The SDS leverages the IT and Web Services developments carried out under the SCIGN/REASoN and ACCESS projects, which have streamlined access to data products for researchers and modelers, and which have created a prototype an on-the-fly interactive research environment through a modern data portal, GPS Explorer. This IT system has been designed using modern IT tools and principles in order to be extensible to any geographic location, scale, natural hazard, and combination of geophysical sensor and related data. We have built upon open GIS standards, particularly those of the OGC, and have used the principles of Web Service-based Service Oriented Architectures to provide scalability and extensibility to new services and capabilities.

To increase teaching of Earth science in schools, and to reflect the interdisciplinary nature and interrelatedness of science disciplines in today's world, we are exploring opportunities for linking Earth science and Biology through engaging and innovative hands-on science activities for the classroom. Through the NSERC-funded Pacific CRYSTAL project based at the University of Victoria, scientists, science educators, and teachers at all levels in the school system are collaborating to research ways of enriching the preparation of students in math and science, and improving the quality of science education from Kindergarten to Grade 12. Our primary foci are building authentic, engaging science experiences for students, and fostering teacher leadership through teacher professional development and training. Interdisciplinary science activities represent an important way of making student science experiences real, engaging and relevant, and provide opportunities to highlight Earth science related topics within other disciplines, and to expand the Earth science taught in schools. The Earth science and Biology interdisciplinary project builds on results and experiences of existing Earth science education activities, and the Seaquaria project. We are developing curriculum-linked activities and resource materials, and hosting teacher workshops, around two initial areas; soils, and marine life and the fossil record. An example activity for the latter is the hands-on examination of organisms occupying the nearshore marine environment using a saltwater aquarium and touch tank or beach fieldtrip, and relating this to a suite of marine fossils to facilitate student thinking about representation of life in the fossil record e.g. which life forms are typically preserved, and how are they preserved? Literacy activities such as fossil obituaries encourage exploration of paleoenvironments and life habits of fossil organisms. Activities and resources are being tested with teachers and student teachers through workshops, at teacher conferences, and participating Faculties of Education.

Problem-Based Learning and Earth System Science - The ESSEA High School Earth System Science Online Course

Myers, R.; Botti, J.

2002-12-01

The high school Earth system science course is web based and designed to meet the professional development needs of science teachers in grades 9-12. Three themes predominate this course: Earth system science (ESS) content, collaborative investigations, and problem-based learning (PBL) methodology. PBL uses real-world contexts for in-depth investigations of a subject matter. Participants predict the potential impacts of the selected event on Earth's spheres and the subsequent feedback and potential interactions that might result. PBL activities start with an ill-structured problem that serves as a springboard to team engagement. These PBL scenarios contain real-world situations. Teams of learners conduct an Earth system science analysis of the event and make recommendations or offer solutions regarding the problem. The course design provides an electronic forum for conversations, debate, development, and application of ideas. Samples of threaded discussions built around ESS thinking in science and PBL pedagogy will be presented.

The high school Earth system science course is web based and designed to meet the professional development needs of science teachers in grades 9-12. Three themes predominate this course: Earth system science (ESS) content, collaborative investigations, and problem-based learning (PBL) methodology. PBL uses real-world contexts for in-depth investigations of a subject matter. Participants predict the potential impacts of the selected event on Earth's spheres and the subsequent feedback and potential interactions that might result. PBL activities start with an ill-structured problem that serves as a springboard to team engagement. These PBL scenarios contain real-world situations.

It has been the tradition of the libraries to support literacy. Now in the realm of Executive Order, Making Open and Machine Readable the New Default for Government Information, May 9, 2013, the library has the responsibility to support geospatial data, big data, earth science data or cyber infrastructure data that may support STEM for educational pipeline stimulation. (Such information can be found at http://www.whitehouse.gov/the-press-office/2013/05/09/executive-order-making-open-and-machine-readable-new-default-government-.) Provided is an Educational Data Curation Framework (EDCF) that has been initiated in Purdue research, geospatial data service engagement and outreach endeavors for future consideration and application to augment such data science and climate literacy needs of future global citizens. In addition, this endorsement of this framework by the GLOBE program may facilitate further EDCF implementations, discussion points and prototypes for libraries. In addition, the ECDF will support teacher-led, placed-based and large scale climate or earth science learning systems where such knowledge transfer of climate or earth science data is effectively transferred from higher education research of cyberinfrastructure use such as, NOAA or NASA, to K-12 teachers and school systems. The purpose of this effort is to establish best practices for sustainable K-12 data science delivery system or GLOBE-provided system (http://vis.globe.gov/GLOBE/) where libraries manage the data curation and data appropriateness as data reference experts for such digital data. Here, the Purdue University Libraries' GIS department works to support soils, LIDAR and water science data experiences to support teacher training for an EDCF development effort. Lastly, it should be noted that the interdisciplinary collaboration and demonstration of library supported outreach partners and national organizations such the GLOBE program may best foster EDCF development. This trend in data science where library roles may emerge is consistent with NASA's wavelength program at http://nasawavelength.org. Mr. Steven Smith, an outreach coordinator, led this Purdue University outreach activity involving the GLOBE program with support by the Purdue University Libraries GIS department.

The Eighth International Workshop for Laser Ranging Instrumentation was held in Annapolis, Maryland in May 1992, and was sponsored by the NASA Goddard Space Flight Center in Greenbelt, Maryland. The workshop is held once every 2 to 3 years under differing institutional sponsorship and provides a forum for participants to exchange information on the latest developments in satellite and lunar laser ranging hardware, software, science applications, and data analysis techniques. The satellite laser ranging (SLR) technique provides sub-centimeter precision range measurements to artificial satellites and the Moon. The data has application to a wide range of Earth and lunar science issues including precise orbit determination, terrestrial reference frames, geodesy, geodynamics, oceanography, time transfer, lunar dynamics, gravity and relativity.

We are developing educational and public outreach programs of the earth and planetary science data using a four-dimensional digital globe system, Dagik Earth. Dagik Earth is a simple and affordable four dimensional (three dimension in space and one dimension in time) presentation system of the earth and planetary scientific results. It can display the Earth and planets in three-dimensional way without glasses, and the time variation of the scientific data can be displayed on the Earth and planets image. It is easier to handle and lower cost than similar systems such as Geocosmos by Miraikan museum, Japan and Science On a Sphere by NOAA. At first it was developed as a presentation tool for public outreach programs in universities and research institutes by earth scientists. And now it is used in classrooms of schools and science museums collaboration with school teachers and museum curators. The three dimensional display can show the Earth and planets in exact form without any distortion, which cannot be achieved with two-dimensional display. Furthermore it can provide a sense of reality. Several educational programs have been developed and carried out in high schools, junior high schools, elementary schools and science centers. Several research institutes have used Dagik Earth in their public outreach programs to demonstrate their novel scientific results to public in universities, research institutes and science cafe events. A community of users and developers of Dagik Earth is being formed in Japan. In the presentation, the outline of Dagik Earth and the educational programs using Dagik Earth will be presented.

Reaching Beyond the Geoscience Stigma: Strategies for Success

NASA Astrophysics Data System (ADS)

Messina, P.; Metzger, E. P.

2004-12-01

The geosciences have traditionally been viewed with less "academic prestige" than other science curricula. Among the effects of this perception are depressed K-16 enrollments; state standards' relegation of Earth and space science concepts to earlier grades; Earth Science assignments to lower-performing students, and sometimes even to under-qualified teachers: all of which simply confirm the misconceptions. Restructuring pre-college science curricula so that Earth Science is placed as a capstone course is one way to enhance student understanding of the geosciences. Research demonstrates that reversing the traditional science course sequence (by offering Physics in the ninth grade) improves student success in subsequent science courses. The "Physics First" movement continues to gain momentum offering a possible niche for the Earth and space sciences beyond middle school. It is also critical to bridge the information gap for those with little or no prior exposure to the Earth sciences, particularly K-12 educators. An Earth systems course developed at San José State University is aligned to our state's standards; it is approved to satisfy geoscience subject matter competency by the California Commission on Teacher Credentialing, making it a popular offering for pre- and in-service teachers. Expanding our audience beyond the Bay Area, the Earth Systems Science Education Alliance courses infuse real-world and hands-on learning in a cohesive online curriculum. Through these courses teachers gain knowledge, share effective pedagogies, and build geography-independent communities.

MiTEP's Collaborative Field Course Design Process Based on Earth Science Literacy Principles

2010-12-01

Michigan Technological University has developed a collaborative process for designing summer field courses for teachers as part of their National Science Foundation funded Math Science Partnership program, called the Michigan Teacher Excellence Program (MiTEP). This design process was implemented and then piloted during two two-week courses: Earth Science Institute I (ESI I) and Earth Science Institute II (ESI II). Participants consisted of a small group of Michigan urban science teachers who are members of the MiTEP program. The Earth Science Literacy Principles (ESLP) served as the framework for course design in conjunction with input from participating MiTEP teachers as well as research done on common teacher and student misconceptions in Earth Science. Research on the Earth Science misconception component, aligned to the ESLP, is more fully addressed in GSA Abstracts with Programs Vol. 42, No. 5. “Recognizing Earth Science Misconceptions and Reconstructing Knowledge through Conceptual-Change-Teaching”. The ESLP were released to the public in January 2009 by the Earth Science Literacy Organizing Committee and can be found at http://www.earthscienceliteracy.org/index.html. Each day of the first nine days of both Institutes was focused on one of the nine ESLP Big Ideas; the tenth day emphasized integration of concepts across all of the ESLP Big Ideas. Throughout each day, Michigan Tech graduate student facilitators and professors from Michigan Tech and Grand Valley State University consistantly focused teaching and learning on the day's Big Idea. Many Earth Science experts from Michigan Tech and Grand Valley State University joined the MiTEP teachers in the field or on campus, giving presentations on the latest research in their area that was related to that Big Idea. Field sites were chosen for their unique geological features as well as for the “sense of place” each site provided. Preliminary research findings indicate that this collaborative design process piloted as ESI I and ESI II was successful in improving MiTEP teacher understanding of Earth Science content and that it was helpful to use the ESLP framework. Ultimately, a small sample of student scores will look at the impact on student learning in the MiTEP teacher classrooms.

The HYSPIRI Decadal Survey Mission: Update on the Mission Concept and Science Objectives for Global Imaging Spectroscopy and Multi-Spectral Thermal Measurements

NASA Technical Reports Server (NTRS)

Green, Robert O.; Hook, Simon J.; Middleton, Elizabeth; Turner, Woody; Ungar, Stephen; Knox, Robert

2012-01-01

The NASA HyspIRI mission is planned to provide global solar reflected energy spectroscopic measurement of the terrestrial and shallow water regions of the Earth every 19 days will all measurements downlinked. In addition, HyspIRI will provide multi-spectral thermal measurements with a single band in the 4 micron region and seven bands in the 8 to 12 micron region with 5 day day/night coverage. A direct broadcast capability for measurement subsets is also planned. This HyspIRI mission is one of those designated in the 2007 National Research Council (NRC) Decadal Survey: Earth Science and Applications from Space. In the Decadal Survey, HyspIRI was recognized as relevant to a range of Earth science and science applications, including climate: "A hyperspectral sensor (e.g., FLORA) combined with a multispectral thermal sensor (e.g., SAVII) in low Earth orbit (LEO) is part of an integrated mission concept [described in Parts I and II] that is relevant to several panels, especially the climate variability panel." The HyspIRI science study group was formed in 2008 to evaluate and refine the mission concept. This group has developed a series of HyspIRI science objectives: (1) Climate: Ecosystem biochemistry, condition & feedback; spectral albedo; carbon/dust on snow/ice; biomass burning; evapotranspiration (2) Ecosystems: Global plant functional types, physiological condition, and biochemistry including agricultural lands (3) Fires: Fuel status, fire frequency, severity, emissions, and patterns of recovery globally (4) Coral reef and coastal habitats: Global composition and status (5) Volcanoes: Eruptions, emissions, regional and global impact (6) Geology and resources: Global distributions of surface mineral resources and improved understanding of geology and related hazards These objectives are achieved with the following measurement capabilities. The HyspIRI imaging spectrometer provides: full spectral coverage from 380 to 2500 at 10 nm sampling; 60 m spatial sampling with a 150 km swath; and fully downlinked coverage of the Earth's terrestrial and shallow water regions every 19 days to provide seasonal cloud-free coverage of the terrestrial surface. The HyspIRI Multi-Spectral Thermal instrument provides: 8 spectral bands from 4 to 12 microns; 60 m spatial sampling with a 600 km swath; and fully downlinked coverage of the Earth's terrestrial shallow water regions every 5 days (day/night) to provide nominally cloud-free monthly coverage. The HyspIRI mission also includes an on-board processing and direct broadcast capability, referred to as the Intelligent Payload Module (IPM), which will allow users with the appropriate antenna to download a subset of the HyspIRI data stream to a local ground station. These science and science application objectives are critical today and uniquely addressed by the combined imaging spectroscopy, thermal infrared measurements, and IPM direct broadcast capability of HyspIRI. Two key objectives are: (1) The global HyspIRI spectroscopic measurements of the terrestrial biosphere including vegetation composition and function to constrain and reduce the uncertainty in climate-carbon interactions and terrestrial biosphere feedback. (2) The global 8 band thermal measurements to provide improved constraint of fire related emissions. In this paper the current HyspIRI mission concept that has been reviewed and refined to its current level of maturity with a Data Products Symposium, Science Workshop and NASA HWorkshop is presented including traceability between the measurements and the science and science application objectives.

Northern Eurasia Earth Science Partnership Initiative in 2013: An Update

NASA Astrophysics Data System (ADS)

Groisman, P. Y.

2013-12-01

Eight years ago Northern Eurasia Earth Science Partnership Initiative (NEESPI) was launched with the release of its Science Plan (http://neespi.org). Gradually, the Initiative was joined by numerous international projects launched in EU, Russia, the United States, Canada, Japan, and China. Throughout its duration, NEESPI served and is serving as an umbrella for more than 160 individual international research projects. Currently, the Initiative is in full swing. The total number of the ongoing NEESPI projects (as on July 2013) is 50 and has changed but slightly compared to its peak (87 in 2008). The past one and one-half years (2012-through mid-2013) were extremely productive in the NEESPI outreach. We organized five Open Science Sessions at the three major Geoscience Unions/Assembly Meetings (AGU, EGU, and JpGU) and four International NEESPI Workshops. The programs of two of these Workshops (in Irkutsk and Petrozavodsk, Russia) included Summer Schools for early career scientists. The list of publications of NEESPI scientists was still incomplete at the time of preparation of this abstract. A large suite of NEESPI articles (59) is currently at different stages of review process for the Forth Special NEESPI Issue of "Environmental Research Letters" (http://iopscience.iop.org/1748-9326/focus/NEESPI4). In the past 12 months, we continued releases of the latest findings in the NEESPI domain in regional monographs with publication of two such monographs devoted to Siberia and Dryland East Asia (Groisman and Gutman eds. 2013 and Chen et al. 2013). Keeping in mind an orderly completion of NEESPI in 2015 and a desire of the NEESPI project leaders and their numerous associates to continue studies of the Northern Eurasia role in the Earth System within the FUTURE EARTH Mega Program, we have begun development of the new set of scientific ideas for regional projects for the post-NEESPI period. The goal is to formulate these ideas (science questions) in such way that they will secure fruitful regional and global research for the next decade (as the NEESPI Science Plan did in 2004) and will use new tools that became available (such as Earth System Models, new remote sensing products and field campaigns). These ideas will be discussed at the Meeting. Cited references: Groisman and Gutman (eds), 2013: Environmental Changes in Siberia: Regional Changes and their Global Consequences.

The EarthServer project: Exploiting Identity Federations, Science Gateways and Social and Mobile Clients for Big Earth Data Analysis

NASA Astrophysics Data System (ADS)

2013-04-01

The EarthServer project (www.earthserver.eu), funded by the European Commission under its Seventh Framework Program, aims at establishing open access and ad-hoc analytics on extreme-size Earth Science data, based on and extending leading-edge Array Database technology. The core idea is to use database query languages as client/server interface to achieve barrier-free "mix & match" access to multi-source, any-size, multi-dimensional space-time data -- in short: "Big Earth Data Analytics" - based on the open standards of the Open Geospatial Consortium Web Coverage Processing Service (OGC WCPS) and the W3C XQuery. EarthServer combines both, thereby achieving a tight data/metadata integration. Further, the rasdaman Array Database System (www.rasdaman.com) is extended with further space-time coverage data types. On server side, highly effective optimizations - such as parallel and distributed query processing - ensure scalability to Exabyte volumes. Six Lighthouse Applications are being established in EarthServer, each of which poses distinct challenges on Earth Data Analytics: Cryospheric Science, Airborne Science, Atmospheric Science, Geology, Oceanography, and Planetary Science. Altogether, they cover all Earth Science domains; the Planetary Science use case has been added to challenge concepts and standards in non-standard environments. In addition, EarthLook (maintained by Jacobs University) showcases use of OGC standards in 1D through 5D use cases. In this contribution we will report on the first applications integrated in the EarthServer Science Gateway and on the clients for mobile appliances developed to access them. We will also show how federated and social identity services can allow Big Earth Data Providers to expose their data in a distributed environment keeping a strict and fine-grained control on user authentication and authorisation. The degree of fulfilment of the EarthServer implementation with the recommendations made in the recent TERENA Study on AAA Platforms For Scientific Resources in Europe (https://confluence.terena.org/display/aaastudy/AAA+Study+Home+Page) will also be assessed.

Dalton, M. C.

1983-01-01

Habitability in space refers to the components, characteristics, conditions, and design parameters that go beyond but include the basic life sustaining requirements. Elements of habitability covered include internal environment, architecture, mobility and restraint, food, clothing, personal hygiene, housekeeping, communications, and crew activities. All elements are interrelated and need to be treated as an overall discipline. Designing for a space station is similar to designing on earth but with 'space rules' instead of ground rules. It is concluded that some habitability problems require behavioral science solutions.

NBL CRM 112-A: A new certified isotopic composition

NASA Astrophysics Data System (ADS)

Thomas, R. B.; Essex, R. M.; Mason, P.

2007-12-01

NBL CRM 112-A Uranium Metal Assay Standard is commonly used as a natural uranium isotopic reference material within the earth science mass spectrometry community. The metal is from the same parent material as NBS SRM 960, the uranyl nitrate solution, CRM 145, and the high-purity uranyl nitrate solution CRM 145-B. Because CRM 112-A has not yet been certified for isotopic composition, it has been assumed that this material has a natural 235U/238U (0.0072527), and the δ234U has been determined by measurement (e.g. -37.1‰; Cheng et al., 2000). These values have been widely used to calibrate the concentration of spikes and standards, and to correct measurements for instrument or mass bias. New, preliminary, isotopic measurements on CRM 145 and CRM 112-A performed at New Brunswick Laboratory suggest that these reference materials have a slightly lower 235U/238U and δ234U than have been commonly used. If this is the case, then data using the accepted values may be slightly biased. The significance of this bias will depend on the uncertainty of the measurement, how the CRM 112-A data is used to correct measurement data, the cited values that were used to correct the data, and the final certified values of the CRM. This fall, New Brunswick Laboratory is certifying the isotopic composition of the CRM 112-A metal using high precision thermal ionization mass spectrometry techniques. Upon completion of certification, the new CRM 112- A standard with certified isotopic ratios will provide the earth science community with a well characterized and traceable reference for calibrating and correcting their mass spectrometry measurement systems.

Learning More About Our Earth: An Exploration of NASA's Contributions to Earth Science Through Remote Sensing Technologies

Lindsay, Francis

2017-01-01

NASA is commonly known for its pioneering work in space exploration and the technological advancements that made access to space possible. NASA is now increasingly known for the agency's research and technologies that support the Earth sciences. This is a presentation focusing on NASA's Earth science efforts told mostly through the technological innovations NASA uses to achieve a greater understanding of the Earth, making it possible to explore the Earth as a system. Enabling this science is NASA's fleet of over two dozen Earth science spacecraft, supported by aircraft, ships and ground observations. NASA's Earth Observing System (EOS) is a coordinated series of polar-orbiting and low inclination satellites for long-term global observations of the land surface, biosphere, solid Earth, atmosphere, and oceans. With the launching of the three flagship satellite missions, Terra, Aqua and Aura, beginning in 1999, NASA's initial Mission to Planet Earth made it possible to measure aspects of the environment that touch the lives of every person around the world. NASA harnessing the unique space-based platform means, fortunately, no planet is better studied than the one we actually live on.

The Curriculum Customization Service: A Tool for Customizing Earth Science Instruction and Supporting Communities of Practice

NASA Astrophysics Data System (ADS)

Melhado, L. C.; Devaul, H.; Sumner, T.

2010-12-01

Accelerating demographic trends in the United States attest to the critical need to broaden access to customized learning: reports refer to the next decade as the era of “extreme diversity” in K-12 classrooms, particularly in large urban school districts. This diverse student body possesses a wide range of knowledge, skills, and abilities in addition to cultural differences. A single classroom may contain students with different levels of quantitative skills, different levels of English language proficiency, and advanced students preparing for college-level science. A uniform curriculum, no matter how well designed and implemented, cannot possibly serve the needs of such diverse learners equally well. Research has shown positive learning outcomes when pedagogical strategies that customize instruction to address specific learner needs are implemented, with under-achieving students often benefiting most. Supporting teachers in the effective adoption and use of technology to meet these instructional challenges is the underlying goal of the work to be presented here. The Curriculum Customization Service (CCS) is an integrated web-based platform for middle and high school Earth science teachers designed to facilitate teachers’ instructional planning and delivery; enhancing existing curricula with digital library resources and shared teacher-contributed materials in the context of articulated learning goals. The CCS integrates interactive resources from the Digital Library for Earth System Education (DLESE) with an inquiry-based curriculum component developed by the American Geological Institute (EarthComm and Investigating Earth Systems). The digital library resources emphasize visualizations and animations of Earth processes that often challenge students’ understanding, offering multiple representations of phenomena to address different learning styles, reading abilities, and preconceived ideas. Teachers can access these materials, as well as those created or contributed by colleagues to create personalized, annotated collections of resources best suited to address the needs of the students in their classroom. Teachers can see the resources that their colleagues are using to customize their instruction, and share their ideas about the suitability of resources for different learners or learning styles through the use of tags and annotations thus creating a community of practice in support of differentiated instruction. A field trial involving 124 middle and high school Earth science teachers in a large urban school district was conducted in the 2009-2010 academic year, accompanied by a mixed-method research and evaluation study to investigate the impact of the use of this system on teacher beliefs and practice, and student learning. This presentation will include a demonstration of the system as well as discuss the results of the research thus far.

The Blueprint for Change: A National Strategy to Enhance Access to Earth and Space Science Education Resources

NASA Astrophysics Data System (ADS)

Geary, E. E.; Barstow, D.

2001-12-01

Enhancing access to high quality science education resources for teachers, students, and the general public is a high priority for the earth and space science education communities. However, to significantly increase access to these resources and promote their effective use will require a coordinated effort between content developers, publishers, professional developers, policy makers, and users in both formal and informal education settings. Federal agencies, academic institutions, professional societies, informal science centers, the Digital Library for Earth System Education, and other National SMETE Digital Library Projects are anticipated to play key roles in this effort. As a first step to developing a coordinated, national strategy for developing and delivering high quality earth and space science education resources to students, teachers, and the general public, 65 science educators, scientists, teachers, administrators, policy makers, and business leaders met this June in Snowmass, Colorado to create "Earth and Space Science Education 2010: A Blueprint for Change". The Blueprint is a strategy document that will be used to guide Earth and space science education reform efforts in grades K-12 during the next decade. The Blueprint contains specific goals, recommendations, and strategies for coordinating action in the areas of: Teacher Preparation and Professional Development, Curriculum and Materials, Equity and Diversity, Assessment and Evaluation, Public Policy and Systemic Reform, Public and Informal Education, Partnerships and Collaborations, and Technology. If you develop, disseminate, or use exemplary earth and space science education resources, we invite you to review the Blueprint for Change, share it with your colleagues and local science educators, and join as we work to revolutionize earth and space science education in grades K-12.

The Federation of Earth Science Information Partners (ESIP Federation): Facilitating Partnerships that Work to Bring Earth Science Data into Educational Settings

NASA Astrophysics Data System (ADS)

Freuder, R.; Ledley, T. S.; Dahlman, L.

2004-12-01

The Federation of Earth Science Information Partners (ESIP Federation, http://www.esipfed.org) formed seven years ago and now with 77 member organizations is working to "increase the quality and value of Earth science products and services .for the benefit of the ESIP Federation's stakeholder communities." Education (both formal and informal) is a huge audience that we serve. Partnerships formed by members within the ESIP Federation have created bridges that close the gap between Earth science data collection and research and the effective use of that Earth science data to explore concepts in Earth system science by the educational community. The Earth Exploration Toolbook is one of those successful collaborations. The Earth Exploration Toolbook (EET, http://serc.carleton.edu/eet) grew out of a need of the educational community (articulated by the Digital Library for Earth System Education (DLESE) community) to have better access to Earth science data and data analysis tools and help in effectively using them with students. It is a collection of web-accessible chapters, each featuring step-by-step instructions on how to use an Earth science dataset and data analysis tool to investigate an issue or concept in Earth system science. Each chapter also provides the teacher information on the outcome of the activity, grade level, standards addressed, learning goals, time required, and ideas for exploring further. The individual ESIP Federation partners alone could not create the EET. However, the ESIP Federation facilitated the partnering of members, drawing from data providers, researchers and education tool developers, to create the EET. Interest in the EET has grown since it went live with five chapters in July 2003. There are currently seven chapters with another six soon to be released. Monthly online seminars in which over a hundred educators have participated have given very positive feedback. Post workshop surveys from our telecon-online workshops indicate that participants have an increased comfort level in using digital libraries, datasets, and scientific tools after working through an EET chapter. The EET is a vehicle that can grow and support new chapter development. An EET chapter template for creating new "chapters" has been devised. Other research-focused members of the ESIP Federation have expressed interest in working with the EET team to facilitate the use of their Earth science data by educators and students. This presentation will describe how the partnerships were forged, how they are maintained, and how the ESIP Federation is facilitating further growth. http://serc.carleton.edu/eet

SCIENCE PARAMETRICS FOR MISSIONS TO SEARCH FOR EARTH-LIKE EXOPLANETS BY DIRECT IMAGING

DOE Office of Scientific and Technical Information (OSTI.GOV)

Brown, Robert A., E-mail: rbrown@stsci.edu

2015-01-20

We use N{sub t} , the number of exoplanets observed in time t, as a science metric to study direct-search missions like Terrestrial Planet Finder. In our model, N has 27 parameters, divided into three categories: 2 astronomical, 7 instrumental, and 18 science-operational. For various ''27-vectors'' of those parameters chosen to explore parameter space, we compute design reference missions to estimate N{sub t} . Our treatment includes the recovery of completeness c after a search observation, for revisits, solar and antisolar avoidance, observational overhead, and follow-on spectroscopy. Our baseline 27-vector has aperture D = 16 m, inner working angle IWAmore » = 0.039'', mission time t = 0-5 yr, occurrence probability for Earth-like exoplanets η = 0.2, and typical values for the remaining 23 parameters. For the baseline case, a typical five-year design reference mission has an input catalog of ∼4700 stars with nonzero completeness, ∼1300 unique stars observed in ∼2600 observations, of which ∼1300 are revisits, and it produces N {sub 1} ∼ 50 exoplanets after one year and N {sub 5} ∼ 130 after five years. We explore offsets from the baseline for 10 parameters. We find that N depends strongly on IWA and only weakly on D. It also depends only weakly on zodiacal light for Z < 50 zodis, end-to-end efficiency for h > 0.2, and scattered starlight for ζ < 10{sup –10}. We find that observational overheads, completeness recovery and revisits, solar and antisolar avoidance, and follow-on spectroscopy are all important factors in estimating N.« less

Four dimensional studies in earth space

NASA Technical Reports Server (NTRS)

Mather, R. S.

1972-01-01

A system of reference which is directly related to observations, is proposed for four-dimensional studies in earth space. Global control network and polar wandering are defined. The determination of variations in the earth's gravitational field with time also forms part of such a system. Techniques are outlined for the unique definition of the motion of the geocenter, and the changes in the location of the axis of rotation of an instantaneous earth model, in relation to values at some epoch of reference. The instantaneous system referred to is directly related to a fundamental equation in geodynamics. The reference system defined would provide an unambiguous frame for long period studies in earth space, provided the scale of the space were specified.

An Analysis of Earth Science Data Analytics Use Cases

NASA Technical Reports Server (NTRS)

Shie, Chung-Lin; Kempler, Steve

2014-01-01

The increase in the number and volume, and sources, of globally available Earth science data measurements and datasets have afforded Earth scientists and applications researchers unprecedented opportunities to study our Earth in ever more sophisticated ways. In fact, the NASA Earth Observing System Data Information System (EOSDIS) archives have doubled from 2007 to 2014, to 9.1 PB (Ramapriyan, 2009; and https:earthdata.nasa.govaboutsystem-- performance). In addition, other US agency, international programs, field experiments, ground stations, and citizen scientists provide a plethora of additional sources for studying Earth. Co--analyzing huge amounts of heterogeneous data to glean out unobvious information is a daunting task. Earth science data analytics (ESDA) is the process of examining large amounts of data of a variety of types to uncover hidden patterns, unknown correlations and other useful information. It can include Data Preparation, Data Reduction, and Data Analysis. Through work associated with the Earth Science Information Partners (ESIP) Federation, a collection of Earth science data analytics use cases have been collected and analyzed for the purpose of extracting the types of Earth science data analytics employed, and requirements for data analytics tools and techniques yet to be implemented, based on use case needs. ESIP generated use case template, ESDA use cases, use case types, and preliminary use case analysis (this is a work in progress) will be presented.

Preliminary Results from NASA/GSFC Ka-Band High Rate Demonstration for Near-Earth Communications

NASA Technical Reports Server (NTRS)

Wong, Yen; Gioannini, Bryan; Bundick, Steven N.; Miller, David T.

2004-01-01

In early 2000, the National Aeronautics and Space Administration (NASA) commenced the Ka-Band Transition Project (KaTP) as another step towards satisfying wideband communication requirements of the space research and earth exploration-satellite services. The KaTP team upgraded the ground segment portion of NASA's Space Network (SN) in order to enable high data rate space science and earth science services communications. The SN ground segment is located at the White Sands Complex (WSC) in New Mexico. NASA conducted the SN ground segment upgrades in conjunction with space segment upgrades implemented via the Tracking and Data Relay Satellite (TDRS)-HIJ project. The three new geostationary data relay satellites developed under the TDRS-HIJ project support the use of the inter-satellite service (ISS) allocation in the 25.25-27.5 GHz band (the 26 GHz band) to receive high speed data from low earth-orbiting customer spacecraft. The TDRS H spacecraft (designated TDRS-8) is currently operational at a 171 degrees west longitude. TDRS I and J spacecraft on-orbit testing has been completed. These spacecraft support 650 MHz-wide Ka-band telemetry links that are referred to as return links. The 650 MHz-wide Ka-band telemetry links have the capability to support data rates up to at least 1.2 Gbps. Therefore, the TDRS-HIJ spacecraft will significantly enhance the existing data rate elements of the NASA Space Network that operate at S-band and Ku-band.

Science Opportunities Enabled by NASA's Constellation System: Interim Report

NASA Technical Reports Server (NTRS)

2008-01-01

In 2004 NASA initiated studies of advanced science mission concepts known as the Vision Missions and inspired by a series of NASA roadmap activities conducted in 2003. Also in 2004 NASA began implementation of the first phases of a new space exploration policy, the Vision for Space Exploration. This implementation effort included development of a new human-carrying spacecraft, known as Orion, and two new launch vehicles, the Ares I and Ares V rockets.collectively called the Constellation System. NASA asked the National Research Council (NRC) to evaluate the science opportunities enabled by the Constellation System (see Preface) and to produce an interim report on a short time schedule and a final report by November 2008. The committee notes, however, that the Constellation System and its Orion and Ares vehicles have been justified by NASA and selected in order to enable human exploration beyond low Earth orbit, and not to enable science missions. This interim report of the Committee on Science Opportunities Enabled by NASA s Constellation System evaluates the 11 Vision Mission studies presented to it and groups them into two categories: those more deserving of future study, and those less deserving of future study. Although its statement of task also refers to Earth science missions, the committee points out that the Vision Missions effort was focused on future astronomy, heliophysics, and planetary exploration and did not include any Earth science studies because, at the time, the NRC was conducting the first Earth science decadal survey, and funding Earth science studies as part of the Vision Missions effort would have interfered with that process. Consequently, no Earth science missions are evaluated in this interim report. However, the committee will evaluate any Earth science mission proposal submitted in response to its request for information issued in March 2008 (see Appendix A). The committee based its evaluation of the preexisting Vision Missions studies on two criteria: whether the concepts offered the potential for a significant scientific advance, and whether or not the concepts would benefit from the Constellation System. The committee determined that all of the concepts offered the possibility of a significant scientific advance, but it cautions that such an evaluation ultimately must be made by the decadal survey process, and it emphasizes that this interim report s evaluation should not be considered to be an endorsement of the scientific merit of these proposals, which must of course be evaluated relative to other proposals. The committee determined that seven of these concepts would benefit from the Constellation System, whereas four would not, but it stresses that this conclusion does not reflect an evaluation of the scientific merit of the projects, but rather an assessment of whether or not new capabilities provided by the Constellation System could significantly affect them. Some of the mission concepts, such as the Advanced Compton Telescope, already offer a significant scientific advance and fit easily within the mass and volume constraints of existing launch vehicles. Other mission concepts, such as the Palmer Quest proposal to drill through the Mars polar cap, are not constrained by the launch vehicle, but rather by other technology limitations. The committee evaluated the mission concepts as presented to it, aware nevertheless that proposing a far larger and more ambitious mission with the same science goals might be possible given the capabilities of the Ares V launch vehicle. (Such proposals can be submitted in response to the committee s request for information to be evaluated in its final report.) See Table S.1 for a summary of the Vision Missions, including their cost estimates, technical maturity, and reasons that they might benefit from the Constellation System. The committee developed several findings and recommendations.

In current ethics debates, the protection of animals and the environment are central themes. In this context, reference is made to "ethics of responsibility". In the reality of scientific life and the conduct of science, "ethics of responsibility" have only had a modest impact. Reflection based on the history of thought may explain this finding. Upon abolishing God, man has redirected an initially religious love and devotion toward himself. The postulate of unfettered dominion over the Earth has become the supreme principle. "Theoria" in the sense of its original meaning, that is a celebratory admiration for sacred Nature, is incomprehensible to modern man. Nature has been stripped of its sanctity and transformed into something to be exploited for its human utility. Consequently, today the credo applies that to interpret the freedom of science according to ethical principles is utterly untenable. The author pleads for reconsideration.

Reuse of Software Assets for the NASA Earth Science Decadal Survey Missions

Mattmann, Chris A.; Downs, Robert R.; Marshall, James J.; Most, Neal F.; Samadi, Shahin

2010-01-01

Software assets from existing Earth science missions can be reused for the new decadal survey missions that are being planned by NASA in response to the 2007 Earth Science National Research Council (NRC) Study. The new missions will require the development of software to curate, process, and disseminate the data to science users of interest and to the broader NASA mission community. In this paper, we discuss new tools and a blossoming community that are being developed by the Earth Science Data System (ESDS) Software Reuse Working Group (SRWG) to improve capabilities for reusing NASA software assets.

NASA Earth Science Research and Applications Using UAVs

NASA Technical Reports Server (NTRS)

Guillory, Anthony R.

2003-01-01

The NASA Earth Science Enterprise sponsored the UAV Science Demonstration Project, which funded two projects: the Altus Cumulus Electrification Study (ACES) and the UAV Coffee Harvest Optimization experiment. These projects were intended to begin a process of integrating UAVs into the mainstream of NASA s airborne Earth Science Research and Applications programs. The Earth Science Enterprise is moving forward given the positive science results of these demonstration projects to incorporate more platforms with additional scientific utility into the program and to look toward a horizon where the current piloted aircraft may not be able to carry out the science objectives of a mission. Longer duration, extended range, slower aircraft speed, etc. all have scientific advantages in many of the disciplines within Earth Science. The challenge we now face are identifying those capabilities that exist and exploiting them while identifying the gaps. This challenge has two facets: the engineering aspects of redesigning or modifying sensors and a paradigm shift by the scientists.

Canadian Geoscience Education Network (CGEN): Fostering Excellence in Earth Science Education and Outreach

NASA Astrophysics Data System (ADS)

Haidl, F. M.; Vodden, C.; Bates, J. L.; Morgan, A. V.

2009-05-01

CGEN, the outreach arm of the Canadian Federation of Earth Sciences, is a network of more than 270 individuals from all over Canada who work to promote geoscience education and public awareness of science. CGEN's priorities are threefold: to improve the quality of Earth science education delivered in our primary and secondary schools; to raise public awareness about the Earth sciences and their impact on everyday life; and to encourage student interest in the Earth sciences as a career option. These priorities are supported by CGEN's six core programs: 1) The national EdGEO program (www.edgeo.org), initiated in the 1970s, supports Earth science workshops for teachers. These workshops, organized by teams of local educators and geoscientists, provide teachers with "enhanced knowledge, classroom resources and increased confidence" to more effectively teach Earth science. In 2008, a record 521 teachers attended 14 EdGEO workshops. 2) EarthNet (www.earthnet-geonet.ca) is a virtual resource centre that provides support for teachers and for geoscientists involved in education and outreach. In 2008, EarthNet received a $11,500 grant from Encana Corporation to develop energy-related content. 3) The new Careers in Earth Science website (www.earthsciencescanada.com/careers), launched in October 2008, enhances CGEN's capacity to encourage students to pursue a career in the Earth sciences. This project exemplifies the value of collaboration with other organizations. Seven groups provided financial support for the project and many other organizations and individuals contributed in-kind support. 4) Geoscape Canada and Waterscape Canada, programs led by the Geological Survey of Canada, communicate practical Earth science information to teachers, students, and other members of communities across Canada through a series of electronic and hard-copy posters and other resources. Many of the resources created from 1998 to 2007 are available online (www.geoscape.nrcan.gc.ca). A northern British Columbia geological highway map was published in 2008. In the works are a geological map for southern British Columbia and three community and regional geoscience guides. 5) What on Earth (www.whatonearth.org), a biannual national newsletter established at the University of Waterloo in 1987, provides a range of Earth science information for teachers in Canada and elsewhere. It was originally published as a colourful printed newsletter, which in recent years was also available online; new issues will be available only online. 6) Friends of Canadian Geoheritage is a new national program currently being piloted in the Ottawa-Gatineau area, where it is working with municipal and other government agencies, schools, universities, and community groups to help preserve, protect and promote Canada's rich geoheritage. A new Geo-Park, a book on building materials in Ottawa, a Geoheritage day, field trips and public talks are just some of the initiatives underway.

Grid Technology as a Cyber Infrastructure for Earth Science Applications

NASA Technical Reports Server (NTRS)

Hinke, Thomas H.

2004-01-01

This paper describes how grids and grid service technologies can be used to develop an infrastructure for the Earth Science community. This cyberinfrastructure would be populated with a hierarchy of services, including discipline specific services such those needed by the Earth Science community as well as a set of core services that are needed by most applications. This core would include data-oriented services used for accessing and moving data as well as computer-oriented services used to broker access to resources and control the execution of tasks on the grid. The availability of such an Earth Science cyberinfrastructure would ease the development of Earth Science applications. With such a cyberinfrastructure, application work flows could be created to extract data from one or more of the Earth Science archives and then process it by passing it through various persistent services that are part of the persistent cyberinfrastructure, such as services to perform subsetting, reformatting, data mining and map projections.

Earth science research requires coordination and collaboration across multiple disparate science domains. Data systems that support this research are often as disparate as the disciplines that they support. These distinctions can create barriers limiting access to measurements, which could otherwise enable cross-discipline Earth science. NASA's Earth Observing System Data and Information System (EOSDIS) is continuing to bridge the gap between discipline-centric data systems with a coherent and transparent system of systems that offers up to date and engaging science related content, creates an active and immersive science user experience, and encourages the use of EOSDIS earth data and services. The new Earthdata Coherent Web (ECW) project encourages cohesiveness by combining existing websites, data and services into a unified website with a common look and feel, common tools and common processes. It includes cross-linking and cross-referencing across the Earthdata site and NASA's Distributed Active Archive Centers (DAAC), and by leveraging existing EOSDIS Cyber-infrastructure and Web Service technologies to foster re-use and to reduce barriers to discovering Earth science data (http://earthdata.nasa.gov).

Scientometrics is the science of science. Scientometric research includes measurements of impact, mapping of scientific fields, and the production of indicators for use in policy and management. We have leveraged network analysis in a scientometric study of the American Geophysical Union (AGU). Data from the AGU's Linked Data Abstract Browser was used to create a visualization and analytics tools to explore the Earth science's research network. Our application applies network theory to look at network structure within the various AGU sections, identify key individuals and communities related to Earth science topics, and examine multi-disciplinary collaboration across sections. Opportunities to optimize Earth science output, as well as policy and outreach applications, are discussed.

Weather, knowledge base and life-style

NASA Astrophysics Data System (ADS)

Bohle, Martin

2015-04-01

Why to main-stream curiosity for earth-science topics, thus to appraise these topics as of public interest? Namely, to influence practices how humankind's activities intersect the geosphere. How to main-stream that curiosity for earth-science topics? Namely, by weaving diverse concerns into common threads drawing on a wide range of perspectives: be it beauty or particularity of ordinary or special phenomena, evaluating hazards for or from mundane environments, or connecting the scholarly investigation with concerns of citizens at large; applying for threading traditional or modern media, arts or story-telling. Three examples: First "weather"; weather is a topic of primordial interest for most people: weather impacts on humans lives, be it for settlement, for food, for mobility, for hunting, for fishing, or for battle. It is the single earth-science topic that went "prime-time" since in the early 1950-ties the broadcasting of weather forecasts started and meteorologists present their work to the public, daily. Second "knowledge base"; earth-sciences are a relevant for modern societies' economy and value setting: earth-sciences provide insights into the evolution of live-bearing planets, the functioning of Earth's systems and the impact of humankind's activities on biogeochemical systems on Earth. These insights bear on production of goods, living conditions and individual well-being. Third "life-style"; citizen's urban culture prejudice their experiential connections: earth-sciences related phenomena are witnessed rarely, even most weather phenomena. In the past, traditional rural communities mediated their rich experiences through earth-centric story-telling. In course of the global urbanisation process this culture has given place to society-centric story-telling. Only recently anthropogenic global change triggered discussions on geoengineering, hazard mitigation, demographics, which interwoven with arts, linguistics and cultural histories offer a rich narrative of humankind's intersections with the geosphere. To gain public's curiosity for earth-science topics, thus to gain attention of various social groups that all have access to a high density of information, digestible rich messages are needed: earth-science story-telling has to weaves earth-science topics into culturally rich narrations of multiple forms offering a wide range of perspectives to which people can connect.

2009-12-01

The United Nations Education Science Culture and Communication Organization (UNESCO) has recently launched a new Earth Science Education Initiative in Africa. The overall intention of this Initiative is to support the development of the next generation of earth scientists in Africa who are equipped with the necessary tools, networks and perspectives to apply sound science to solving and benefiting from the challenges and opportunities of sustainable development. The opportunities in the earth sciences are great, starting with traditional mineral extraction and extending into environmental management such as climate change adaptation, prevention of natural hazards, and ensuring access to drinking water. The Earth Science Education Initiative has received strong support from many different types of partners. Potential partners have indicated an interest to participate as organizational partners, content providers, relevant academic institutes, and funders. Organizational partners now include the Geological Society of Africa (GSAf), International Center for Training and Exchanges in the Geosciences (CIFEG), Association of African Women Geoscientists (AAWG), International Year of Planet Earth (IYPE), and International Union of Geological Sciences (IUGS). The activities and focus of the Initiative within the overall intention is being developed in a participatory manner through a series of five regional workshops in Africa. The objective of these workshops is to assess regional capacities and needs in earth science education, research and industry underlining existing centers of excellence through conversation with relevant regional and international experts and plotting the way ahead for earth science education. This talk will provide an update on the outcomes of the first three workshops which have taken place in Luanda, Angola; Assiut, Egypt; and Cape Town; South Africa.

1982-01-01

The report develops a ten-year science strategy for investigating the solid earth and dynamics of world oceans from Earth orbit. The strategy begins from the premise that earth studies have proceeded to the point where further advances in understanding Earth processes must be based on a global perspective and that the U.S. is technically ready to begin a global study approach from Earth orbit. The major areas of study and their fundamental problems are identified. The strategy defines the primary science objectives to be addressed and the essential measurements and precision to achieve them.

New York State is experiencing a lack of qualified Earth Science teachers, leading in the short term to a reduction in students who successfully complete the Earth Science Regents examination, and in the long term potential reductions in the number of students who go on to pursue college degrees in Earth Science related disciplines. The MAT program addresses this problem via a collaboration between practicing research scientists and education faculty. The faculty consists of curators and postdoctoral researchers from the Departments of Astrophysics, Earth and Planetary Sciences, and the Division of Paleontology, as well as doctoral-level education experts. During the 15-month, full-time program, students participate in a residency program at local urban classrooms as well as taking courses and completing field work in astrophysics, geology, earth science, and paleontology. The program targets high-needs schools with diverse populations. We seek to encourage, stimulate interest, and inform the students impacted by our program, most of whom are from traditionally underrepresented backgrounds, about the rich possibilities for careers in Earth Science related disciplines and the intrinsic value of the subject. We report on the experience of the first and second cohorts, all of whom are now employed in full time teaching positions, and the majority in high needs schools in New York State.

2003-12-01

Science education reform has skyrocketed over the last decade thanks in large part to the technology of the Internet, opening up dynamic new online communities of learners. It has allowed educators worldwide to share thoughts about Earth system science and reexamine the way science is taught. The Earth System Science Education Alliance (ESSEA) is one positive offshoot of this reform effort. This developing partnership among universities, colleges, and science education organizations is led by the Institute for Global Environmental Strategies and the Center for Educational TechnologiesTM at Wheeling Jesuit University. ESSEA's mission is to improve Earth system science education. ESSEA has developed three Earth system science courses for K-12 teachers. These online courses guide teachers into collaborative, student-centered science education experiences. Not only do these courses support teachers' professional development, they also help teachers implement Earth systems science content and age-appropriate pedagogical methods into their classrooms. The ESSEA semester-long courses are open to elementary, middle school, and high school educators. After three weeks of introductory content, teachers develop content and pedagogical and technological knowledge in four three-week learning cycles. The elementary school course focuses on basic Earth system interactions between land, life, air, and water. The middle school course stresses the effects of real-world events-volcanic eruptions, hurricanes, rainforest destruction-on Earth's lithosphere, atmosphere, biosphere, and hydrosphere, using "jigsaw" to study the interactions between events, spheres, and positive and negative feedback loops. The high school course uses problem-based learning to examine critical areas of global change, such as coral reef degradation, ozone depletion, and climate change. This ESSEA presentation provides examples of learning environments from each of the three courses.

Lunar Laser Ranging: Glorious Past And A Bright Future

NASA Astrophysics Data System (ADS)

Shelus, Peter J.

Lunar Laser Ranging (LLR), a part of the NASA Apollo program, has beenon-going for more than 30 years. It provides the grist for a multi-disciplinarydata analysis mill. Results exist for solid Earth sciences, geodesy and geodynamics,solar system ephemerides, terrestrial and celestial reference frames, lunar physics,general relativity and gravitational theory. Combined with other data, it treatsprecession of the Earth''s spin axis, lunar induced nutation, polar motion/Earthrotation, Earth orbit obliquity to the ecliptic, intersection of the celestial equatorwith the ecliptic, luni-solar solid body tides, lunar tidal deceleration, lunar physicaland free librations, structure of the moon and energy dissipation in the lunar interior.LLR provides input to lunar surface cartography and surveying, Earth station and lunar retroreflector location and motion, mass of the Earth-moon system, lunar and terrestrial gravity harmonics and Love numbers, relativistic geodesic precession, and the equivalence principle of general relativity. With the passive nature of the reflectors and steady improvement in observing equipment and data analysis, LLR continues to provide state-of-the-art results. Gains are steady as the data-base expands. After more than 30 years, LLR remains the only active Apollo experiment. It is important to recognize examples of efficient and cost effective progress of research. LLR is just such an example.

Effects of rotation on crystal settling in a terrestrial magma ocean: Spherical shell model

NASA Astrophysics Data System (ADS)

Maas, C.; Hansen, U.

2015-12-01

Like Moon or Mars, Earth experienced one or several deep magma ocean periods of globalextent in a later stage of its accretion. The crystallization of these magma oceans is of keyimportance for the chemical structure of Earth, the mantle evolution and the onset of platetectonics. Due to the fast rotation of early Earth and the small magma viscosity, rotationprobably had a profound effect on differentiation processes. For example, Matyska et al.[1994] propose that the distribution of heterogeneities like the two large low shear velocityprovinces (LLSVP) at the core mantle boundary is influenced by rotational dynamicsof early Earth. Further Garnero and McNamara [2008] suggest that the LLSVPs arevery long-living anomalies, probably reaching back to the time of differentiation andsolidification of Earth. However, nearly all previous studies neglect the effects of rotation.In our previous work using a Cartesian model, a strong influence of rotation as well asof latitude on the differentiation processes in an early magma ocean was revealed. Weshowed that crystal settling in an early stage of magma ocean crystallization cruciallydepends on latitude as well as on rotational strength and crystal density.In order to overcome the restrictions as to the geometry of the Cartesian model, we arecurrently developing a spherical model to simulate crystal settling in a rotating sphericalshell. This model will allow us not only to investigate crystal settling at the poles andthe equator, but also at latitudes in-between these regions, as well as the migration ofcrystals between poles and equator.

2007-05-01

A recent National Academy of Sciences report recommends that science educators focus strategically on teaching the practice of science. To accomplish this, we have devised and implemented the Science Performance Laboratory, a collaborative research, education, and workforce model that brings scientists and science educators together to conduct scientific inquiry. In this session, we demonstrate how to form active inquiry teams around Arctica Science Research content areas related to the International Polar Year. We use the term "Arctica Science Research" to refer to the entire scope of exploration and discovery relating to: polar science and its global connections; Arctic and Antarctic research and climate sciences; ice and cryospheric studies on Earth; polar regions of the Moon, Mars, and Mercury; icy worlds throughout the Solar System, such as Europa, Enceladus, Titan, Pluto and the Comets; cryovolcanism; ice in interstellar space, and beyond. We apply the notion of teaching the practice science by enacting three effective strategies: 1) The Inquiry Wheel Game, in which we develop an expanded understanding of what has been traditionally taught as "the scientific method"; 2) Acting Out the Science Story, in which we develop a physicalized expression of our conceptual understanding; and 3) Selecting Success Criteria for Inquiry Coaching, in which we reframe how we evaluate science learning as we teach the practice of science.

Mote, A. S.; Ellins, K. K.; Haddad, N.

2011-12-01

Humans are modifying planet Earth at an alarming rate without fully understanding how our actions will affect the atmosphere, hydrosphere, or biosphere. Recognizing the value of educating people to become citizens who can make informed decisions about Earth's resources and challenges, Texas currently offers Earth and Space Science as a rigorous high school capstone course. The new course has created a need for high quality instructional resources and professional development to equip teachers with the most up to date content knowledge, pedagogical approaches, and technological skills to be able to teach a rigorous Earth and Space Science course. As a participant in the NSF-sponsored Texas Earth and Space Science (TXESS) Revolution teacher professional development program, I was selected to participate in a curriculum development project led by TERC to create Earth System Science and climate change resources for the EarthLabs collection. To this end, I am involved in multiple phases of the EarthLabs project, including reviewing the lab-based units during the development phase, pilot teaching the units with my students, participating in research, and ultimately delivering professional development to other teachers to turn them on to the new modules. My partnership with the EarthLabs project has strengthened my teaching practice by increasing my involvement with curriculum development and collaboration and interaction with other Earth science educators. Critically evaluating the lab modules prior to delivering the lessons to my students has prepared me to more effectively teach the EarthLabs modules in my classroom and present the material to other teachers during professional development workshops. The workshop was also strengthened by planning meetings held with EarthLabs partner teachers in which we engaged in lively discussions regarding misconceptions in Earth science, held by both students and adults, and pedagogical approaches to uncover these misconceptions. Collaboration and discussion among members of the EarthLabs team and partner teachers was instrumental to improving the quality of the EarthLabs modules and the professional development workshop. Furthermore, leading the workshop alongside other partner teachers gave me the confidence and experience to deliver professional development to my colleagues and introduce the newly developed EarthLabs modules to other teachers. In this session I will share my experiences and report on the successes, challenges, and lessons learned from being a part of the EarthLabs curriculum and professional development process.

MODster: Namespaces and Redirection for Earth Science Data

NASA Astrophysics Data System (ADS)

Frew, J.; Metzger, D.; Slaughter, P.

2005-12-01

MODster is a distributed, decentralized inventory server for Earth science data granules (standard units of data content and structure.) MODster connects data granule users (people who know which specific granule they want, but who don't know who has it or how to get it) with data granule providers (people or institutions that keep granules accessible online.) * If you're a provider, you can tell MODster which granules you have and where they live (i.e., their URLs.) * If you're a user, you can ask MODster for a granule, and it will transparently redirect your request to whomever has it. The key to making this work is a standard granule namespace. A granule namespace is a naming convention that associates particular names with particular granules, regardless of where those granules live. Different Earth science data products have their own granule namespaces. For example, in the MODIS granule namespace, the granule name "MOD43A2.A1998365.h5.v8.001.1999001090020.hdf" always refers to version 1 of the 5th horizontal and 8th vertical tile of the Level 3 16-day Bi-directional Reflectance Distribution Function product, acquired by the MODIS Terra sensor on 31 December 1998 and generated on 01 January 1999 at 9:00:20 AM. A MODster URL is simply a standard way of referring to a data product namespace and one of its granules. MODster URLs have the general form "http://server/namespace/granule" where "granule" is a granule name that conforms to a granule namespace, "namespace" is a MODster namespace, which is the name of a granule namespace whose conventions are known to MODster, and "server" is a MODster server, which is an HTTP server that can redirect namespace/granule requests to granule providers. A MODster URL with no granule component gets a description of the MODster namespace, its authority (the persons or institutions responsible for documenting and maintaining the naming convention), and also any services for that MODster namespace that the MODster server supports. Our current MODster implementation allows granule providers to explicitly register their granules, and can also crawl provider sites looking for granules whose names match specific rules or regular expressions.

In the spring of 2004, the U.S. Geological Survey (USGS) Menlo Park Center Council commissioned an interdisciplinary working group to develop a forward-looking science strategy for the USGS Menlo Park Science Center in California (hereafter also referred to as "the Center"). The Center has been the flagship research center for the USGS in the western United States for more than 50 years, and the Council recognizes that science priorities must be the primary consideration guiding critical decisions made about the future evolution of the Center. In developing this strategy, the working group consulted widely within the USGS and with external clients and collaborators, so that most stakeholders had an opportunity to influence the science goals and operational objectives.The Science Goals are to: Natural Hazards: Conduct natural-hazard research and assessments critical to effective mitigation planning, short-term forecasting, and event response. Ecosystem Change: Develop a predictive understanding of ecosystem change that advances ecosystem restoration and adaptive management. Natural Resources: Advance the understanding of natural resources in a geologic, hydrologic, economic, environmental, and global context. Modeling Earth System Processes: Increase and improve capabilities for quantitative simulation, prediction, and assessment of Earth system processes.The strategy presents seven key Operational Objectives with specific actions to achieve the scientific goals. These Operational Objectives are to:Provide a hub for technology, laboratories, and library services to support science in the Western Region. Increase advanced computing capabilities and promote sharing of these resources. Enhance the intellectual diversity, vibrancy, and capacity of the work force through improved recruitment and retention. Strengthen client and collaborative relationships in the community at an institutional level.Expand monitoring capability by increasing density, sensitivity, and efficiency and reducing costs of instruments and networks. Encourage a breadth of scientific capabilities in Menlo Park to foster interdisciplinary science. Communicate USGS science to a diverse audience.

Identity crisis - am I a librarian or a geologist? Why not both.

NASA Astrophysics Data System (ADS)

Ramdeen, S.

2015-12-01

As a doctoral candidate, in the 'early stages' of my professional career, I constantly have to remind people I actually already had a career. I am still in the early stages of my career as an academic and information scientist. But before starting my doctoral program, I worked as a geologist for 7 years. During that time I've worked on a drill rig and collected data in the field. I've described cores and cuttings in order to map aquifers. I wrote grants and worked on teams. Now, as an information scientist I look at how researchers access, discover and reuse existing data sets. It involves understanding how data is used, created, and how scientists think about finding data. It hasn't been an easy change, but lately the two domains are converging in the form of data scientists. The change in my career happened organically. The needs of my organization dictated the skills I developed. I thought these needs were just issues in my organization but then I found many other organizations asking the same question. Through the United States Geological Survey's National Geological and Geophysical Data Preservation Program (NGGDPP), I met other geologists working with physical data, and dealing with access, discoverability, and data usage. I found a number of member communities within groups such as the Earth Science Information Partners (ESIP), the Research Data Alliance (RDA), EarthCube, and the American Association of Petroleum Geologists (AAPG) working to on similar questions related to earth science data. Most importantly, I have found that ideas and concepts from my experience with data curation, archives, reference, metadata, organization of information and other library science topics have prepared me to help find solutions to these questions. As the concept of libraries change, so too must the role of the librarian. With this presentation I will discuss my unique career path and how I believe domain sciences and information science can benefit from each other.

Tracking Provenance of Earth Science Data

Tremendous volumes of data have been captured, archived and analyzed. Sensors, algorithms and processing systems for transforming and analyzing the data are evolving over time. Web Portals and Services can create transient data sets on-demand. Data are transferred from organization to organization with additional transformations at every stage. Provenance in this context refers to the source of data and a record of the process that led to its current state. It encompasses the documentation of a variety of artifacts related to particular data. Provenance is important for understanding and using scientific datasets, and critical for independent confirmation of scientific results. Managing provenance throughout scientific data processing has gained interest lately and there are a variety of approaches. Large scale scientific datasets consisting of thousands to millions of individual data files and processes offer particular challenges. This paper uses the analogy of art history provenance to explore some of the concerns of applying provenance tracking to earth science data. It also illustrates some of the provenance issues with examples drawn from the Ozone Monitoring Instrument (OMI) Data Processing System (OMIDAPS) run at NASA's Goddard Space Flight Center by the first author.

NASAs Glenn Research Center (GRC) defines and develops advanced technology for high priority national needs in communications technologies for application to aeronautics and space. GRC tasked Computer Networks and Software Inc. (CNS) to examine protocols and architectures for an In-Space Internet Node. CNS has developed a methodology for network reference models to support NASAs four mission areas: Earth Science, Space Science, Human Exploration and Development of Space (REDS), Aerospace Technology. CNS previously developed a report which applied the methodology, to three space Internet-based communications scenarios for future missions. CNS conceptualized, designed, and developed space Internet-based communications protocols and architectures for each of the independent scenarios. GRC selected for further analysis the scenario that involved unicast communications between a Low-Earth-Orbit (LEO) International Space Station (ISS) and a ground terminal Internet node via a Tracking and Data Relay Satellite (TDRS) transfer. This report contains a tradeoff analysis on the selected scenario. The analysis examines the performance characteristics of the various protocols and architectures. The tradeoff analysis incorporates the results of a CNS developed analytical model that examined performance parameters.

This paper describes the Earth Observing System (EOS) Communication (Ecom) Modeling, Analysis, and Testbed (EMAT) activity performed by Code 540 in support of the Ecom project. Ecom is the ground-to-ground data transport system for operational EOS traffic. The National Aeronautic and Space Administration (NASA) Communications (Nascom) Division, Code 540, is responsible for implementing Ecom. Ecom interfaces with various systems to transport EOS forward link commands, return link telemetry, and science payload data. To understand the complexities surrounding the design and implementation of Ecom, it is necessary that sufficient testbedding, modeling, and analysis be conducted prior to the design phase. These activities, when grouped, are referred to as the EMAT activity. This paper describes work accomplished to date in each of the three major EMAT activities: modeling, analysis, and testbedding.

2001-01-01

The purpose of this investigation is to determine the feasibility of attaining and maintaining unique non-Keplerian orbit vantage locations in the Earth/Moon environment in order to obtain continuous scientific measurements. The principal difficulty associated with obtaining continuous measurements is the temporal nature of astrodynamics, i.e., classical orbits. This investigation demonstrates advanced trajectory designs to meet demanding science requirements which cannot be met following traditional orbital mechanic logic. Examples of continuous observer missions addressed include Earth pole-sitters and unique vertical libration orbits that address Sun-Earth Connection and Earth Science Vision roadmaps.

During the 2009-2010 school year, 40% of New York City (NYC) Earth science teachers were not certified to teach Earth science [New York State Education Department (NYSED), 2011]. This highlights a longstanding shortage of certified teachers, which persists today and prevents many schools from offering courses on the subject, thus diminishing student opportunities to study or embark on careers in Earth science. More generally, the paucity of qualified, effective science teachers hinders student achievement in science, technology, engineering, and mathematics (STEM), and research has consistently shown that improving the quality of teaching substantially increases achievement in STEM-related fields [National Science Board, 2007]. With only 36% of NYC 8th graders scoring at or above the basic level of proficiency in science and with even lower scores for African-American and Hispanic students [Livingston and Wirt, 2005], the need for more qualified science teachers is clear.

Interacting with Petabytes of Earth Science Data using Jupyter Notebooks, IPython Widgets and Google Earth Engine

Erickson, T. A.; Granger, B.; Grout, J.; Corlay, S.

2017-12-01

The volume of Earth science data gathered from satellites, aircraft, drones, and field instruments continues to increase. For many scientific questions in the Earth sciences, managing this large volume of data is a barrier to progress, as it is difficult to explore and analyze large volumes of data using the traditional paradigm of downloading datasets to a local computer for analysis. Furthermore, methods for communicating Earth science algorithms that operate on large datasets in an easily understandable and reproducible way are needed. Here we describe a system for developing, interacting, and sharing well-documented Earth Science algorithms that combines existing software components: Jupyter Notebook: An open-source, web-based environment that supports documents that combine code and computational results with text narrative, mathematics, images, and other media. These notebooks provide an environment for interactive exploration of data and development of well documented algorithms. Jupyter Widgets / ipyleaflet: An architecture for creating interactive user interface controls (such as sliders, text boxes, etc.) in Jupyter Notebooks that communicate with Python code. This architecture includes a default set of UI controls (sliders, dropboxes, etc.) as well as APIs for building custom UI controls. The ipyleaflet project is one example that offers a custom interactive map control that allows a user to display and manipulate geographic data within the Jupyter Notebook. Google Earth Engine: A cloud-based geospatial analysis platform that provides access to petabytes of Earth science data via a Python API. The combination of Jupyter Notebooks, Jupyter Widgets, ipyleaflet, and Google Earth Engine makes it possible to explore and analyze massive Earth science datasets via a web browser, in an environment suitable for interactive exploration, teaching, and sharing. Using these environments can make Earth science analyses easier to understand and reproducible, which may increase the rate of scientific discoveries and the transition of discoveries into real-world impacts.

Bridging the Gap between Earth Science and Students: An Integrated Approach using NASA Earth Science Climate Data

2007-01-01

Under the auspices of the Department of Education's No Child Left Behind (NCLB) Act, beginning in 2007 students will be tested in the science area. There are many techniques that educators can employ to teach students science. The use of authentic materials or in this case authentic data can be an engaging alternative to more traditional methods. An Earth science classroom is a great place for the integration of authentic data and science concepts. The National Aeronautics and Space Administration (NASA) has a wealth of high quality Earth science data available to the general public. For instance, the Atmospheric Science Data Center (ASDC) at NASA s Langley Research Center houses over 800 Earth science data sets related to Earth's radiation budget, clouds, aerosols and tropospheric chemistry. These data sets were produced to increase academic understanding of the natural and anthropogenic factors that influence global climate; however, a major hurdle in using authentic data is the size of the data and data documentation. To facilitate the use of these data sets for educational purposes, the Mentoring and inquirY using NASA Data on Atmospheric and Earth science for Teachers and Amateurs (MY NASA DATA) project has been established to systematically support educational activities at all levels of formal and informal education. The MY NASA DATA project accomplishes this by reducing these large data holdings to microsets that are easily accessible and explored by K-12 educators and students though the project's Web page. MY NASA DATA seeks to ease the difficulty in understanding the jargon-heavy language of Earth science. This manuscript will show how MY NASA DATA provides resources for NCLB implementation in the science area through an overview of the Web site, the different microsets available, the lesson plans and computer tools, and an overview of educational support mechanisms.

This study investigated students' learning environment preferences and compared the relative effectiveness of instructional approaches on students' learning outcomes in achievement and attitude among 10th grade earth science classes in Taiwan. Data collection instruments include the Earth Science Classroom Learning Environment Inventory and Earth Science Learning Outcomes Inventory. The results showed that most students preferred learning in a classroom environment where student-centered and teacher-centered instructional approaches coexisted over a teacher-centered learning environment. A multivariate analysis of covariance also revealed that the STBIM students' cognitive achievement and attitude toward earth science were enhanced when the learning environment was congruent with their learning environment preference.

2009-04-01

There are many effective methods for teaching earth science education that are being successfully used during the fourth International Polar Year (IPY). Relevance of IPY and the polar regions is better understood using a systems thinking approach used in earth science education. Changes in components of the earth system have a global effect; and changes in the polar regions will affect the rest of the world regions and vice versa. Teaching strategies successfully used for primary, secondary, undergraduate and graduate student earth science education and IPY education outreach include: 1) engaging students in earth science or environmental research relevant to their locale; 2) blending lectures with research expeditions or field studies, 3) connecting students with scientists in person and through audio and video conferencing; 4) combining science and arts in teaching, learning and communicating about earth science and the polar regions, capitalizing on the uniqueness of polar regions and its inhabitants, and its sensitivity to climate change; and 5) integrating different perspectives: western science, indigenous and community knowledge in the content and method of delivery. Use of these strategies are exemplified in IPY projects in the University of the Arctic IPY Higher Education Outreach Project cluster such as the GLOBE Seasons and Biomes project, the Ice Mysteries e-Polar Books: An Innovative Way of Combining Science and Literacy project, the Resilience and Adaptation Integrative Graduate Education and Research Traineeship project, and the Svalbard Research Experience for Undergraduates project.

Texas teachers have expressed a need for engaging activities for use in high school Earth science courses. With funding from the NSF, geoscience and education faculty from different institutions around the state collaborated with ten Earth science teachers to create five online Earth science instructional blueprints. The work is part of the DIG (Diversity and Innovation for Geosciences) Texas Instructional Blueprint project. A blueprint stitches together nine units for a yearlong Earth science course (scope and sequence). Each unit covers three weeks of teaching and contains lectures, readings, visualizations, lab investigations, learning activities, and other educational materials from credible sources, which are aligned with Texas state science standards for Earth and Space Science and the Earth Science Literacy Principles. Taken together, the collection of activities address the Next Generation Science Standards (NGSS). During summer 2014, three minority-serving secondary teachers completed a six-week internship at The University of Texas Institute for Geophysics (UTIG). As DIG Texas Education Interns, we organized and revised the content of the units, created scaffolding notes, and built blueprints by selecting groups of nine units from the project's current collection of twenty-one units. Because fieldwork is an important element of geoscience learning, we integrated virtual field trips into each unit. We (1) gained expertise in selecting high quality activities that directly correlate with state standards and address the Earth Science Literacy Principles; (2) developed a keen awareness of the value of the NGSS; (3) learned how to navigate through the NGSS website to track the relationships between the Science and Engineering Practices, Disciplinary Core Ideas, and Crosscutting Concepts for Earth science, as well as connections to other disciplines in the same grade level. Collaborating with other secondary Earth science teachers introduced each of us to new teaching practices, allowing us to build relationships that we expect to last for many years. UTIG researchers mentored and introduced us to their research and methodology. In addition, they helped us find high quality activities for the units. In turn, we shared our knowledge of pedagogy and classroom expertise with them.

An Efficient Approach for Mars Sample Return Using Emerging Commercial Capabilities

Mars Sample Return is the highest priority science mission for the next decade as recommended by the 2011 Decadal Survey of Planetary Science. This article presents the results of a feasibility study for a Mars Sample Return mission that efficiently uses emerging commercial capabilities expected to be available in the near future. The motivation of our study was the recognition that emerging commercial capabilities might be used to perform Mars Sample Return with an Earth-direct architecture, and that this may offer a desirable simpler and lower cost approach. The objective of the study was to determine whether these capabilities can be used to optimize the number of mission systems and launches required to return the samples, with the goal of achieving the desired simplicity. All of the major element required for the Mars Sample Return mission are described. Mission system elements were analyzed with either direct techniques or by using parametric mass estimating relationships. The analysis shows the feasibility of a complete and closed Mars Sample Return mission design based on the following scenario: A SpaceX Falcon Heavy launch vehicle places a modified version of a SpaceX Dragon capsule, referred to as "Red Dragon", onto a Trans Mars Injection trajectory. The capsule carries all the hardware needed to return to Earth Orbit samples collected by a prior mission, such as the planned NASA Mars 2020 sample collection rover. The payload includes a fully fueled Mars Ascent Vehicle; a fueled Earth Return Vehicle, support equipment, and a mechanism to transfer samples from the sample cache system onboard the rover to the Earth Return Vehicle. The Red Dragon descends to land on the surface of Mars using Supersonic Retropropulsion. After collected samples are transferred to the Earth Return Vehicle, the single-stage Mars Ascent Vehicle launches the Earth Return Vehicle from the surface of Mars to a Mars phasing orbit. After a brief phasing period, the Earth Return Vehicle performs a Trans Earth Injection burn. Once near Earth, the Earth Return Vehicle performs Earth and lunar swing-bys and is placed into a Lunar Trailing Orbit - an Earth orbit, at lunar distance. A retrieval mission then performs a rendezvous with the Earth Return Vehicle, retrieves the sample container, and breaks the chain of contact with Mars by transferring the sample into a sterile and secure container. With the sample contained, the retrieving spacecraft makes a controlled Earth re-entry preventing any unintended release of Martian materials into the Earth's biosphere. The mission can start in any one of three Earth to Mars launch opportunities, beginning in 2022.

Efficiently Communicating Rich Heterogeneous Geospatial Data from the FeMO2008 Dive Cruise with FlashMap on EarthRef.org

EarthRef.org is comprehensive and convenient resource for Earth Science reference data and models. It encompasses four main portals: the Geochemical Earth Reference Model (GERM), the Magnetics Information Consortium (MagIC), the Seamount Biogeosciences Network (SBN), and the Enduring Resources for Earth Science Education (ERESE). Their underlying databases are publically available and the scientific community has contributed widely and is urged to continue to do so. However, the net result is a vast and largely heterogeneous warehouse of geospatial data ranging from carefully prepared maps of seamounts to geochemical data/metadata, daily reports from seagoing expeditions, large volumes of raw and processed multibeam data, images of paleomagnetic sampling sites, etc. This presents a considerable obstacle for integrating other rich media content, such as videos, images, data files, cruise tracks, and interoperable database results, without overwhelming the web user. The four EarthRef.org portals clearly lend themselves to a more intuitive user interface and has, therefore, been an invaluable test bed for the design and implementation of FlashMap, a versatile KML-driven geospatial browser written for reliability and speed in Adobe Flash. FlashMap allows layers of content to be loaded and displayed over a streaming high-resolution map which can be zoomed and panned similarly to Google Maps and Google Earth. Many organizations, from National Geographic to the USGS, have begun using Google Earth software to display geospatial content. However, Google Earth, as a desktop application, does not integrate cleanly with existing websites requiring the user to navigate away from the browser and focus on a separate application and Google Maps, written in Java Script, does not scale up reliably to large datasets. FlashMap remedies these problems as a web-based application that allows for seamless integration of the real-time display power of Google Earth and the flexibility of the web without losing scalability and control of the base maps. Our Flash-based application is fully compatible with KML (Keyhole Markup Language) 2.2, the most recent iteration of KML, allowing users with existing Google Earth KML files to effortlessly display their geospatial content embedded in a web page. As a test case for FlashMap, the annual Iron-Oxidizing Microbial Observatory (FeMO) dive cruise to the Loihi Seamount, in conjunction with data available from ongoing and published FeMO laboratory studies, showcases the flexibility of this single web-based application. With a KML 2.2 compatible web-service providing the content, any database can display results in FlashMap. The user can then hide and show multiple layers of content, potentially from several data sources, and rapidly digest a vast quantity of information to narrow the search results. This flexibility gives experienced users the ability to drill down to exactly the record they are looking for (SERC at Carleton College's educational application of FlashMap at http://serc.carleton.edu/sp/erese/activities/22223.html) and allows users familiar with Google Earth the ability to load and view geospatial data content within a browser from any computer with an internet connection.

Unique spectroscopic properties of isolated rare earth ions in solids offer optical linewidths rivaling those of trapped single atoms and enable a variety of recent applications. We design rare-earth-doped crystals, ceramics, and fibers with persistent or transient "spectral hole" recording properties for applications including high-bandwidth optical signal processing where light and our solids replace the high-bandwidth portion of the electronics; quantum cryptography and information science including the goal of storage and recall of single photons; and medical imaging technology for the 700-900 nm therapeutic window. Ease of optically manipulating rare-earth ions in solids enables capturing complex spectral information in 105 to 108 frequency bins. Combining spatial holography and spectral hole burning provides a capability for processing high-bandwidth RF and optical signals with sub-MHz spectral resolution and bandwidths of tens to hundreds of GHz for applications including range-Doppler radar and high bandwidth RF spectral analysis. Simply stated, one can think of these crystals as holographic recording media capable of distinguishing up to 108 different colors. Ultra-narrow spectral holes also serve as a vibration-insensitive sub-kHz frequency reference for laser frequency stabilization to a part in 1013 over tens of milliseconds. The unusual properties and applications of spectral hole burning of rare earth ions in optical materials are reviewed. Experimental results on the promising Tm3+:LiNbO3 material system are presented and discussed for medical imaging applications. Finally, a new application of these materials as dynamic optical filters for laser noise suppression is discussed along with experimental demonstrations and theoretical modeling of the process.

Earth Science research data, its data management, informatics processing and its data curation are valuable in allowing earth scientists to make new discoveries. But how to actively manage these research assets to ensure them safe and secure, accessible and reusable for long term is a big challenge. Nowadays, the data deluge makes this challenge become even more difficult. To address the growing demand for managing earth science data, the Council on Library and Information Resources (CLIR) partners with the Library and Technology Services (LTS) of Lehigh University and Purdue University Libraries (PUL) on hosting postdoctoral fellows in data curation activity. This inter-disciplinary fellowship program funded by the SLOAN Foundation innovatively connects university libraries and earth science departments and provides earth science Ph.D.'s opportunities to use their research experiences in earth science and data curation trainings received during their fellowship to explore best practices for research data management in earth science. In the process of exploring best practices for data curation in earth science, the CLIR Data Curation Fellows have accumulated rich experiences and insights on the data management behaviors and needs of earth scientists. Specifically, Ting Wang, the postdoctoral fellow at Lehigh University has worked together with the LTS support team for the College of Arts and Sciences, Web Specialists and the High Performance Computing Team, to assess and meet the data management needs of researchers at the Department of Earth and Environmental Sciences (EES). By interviewing the faculty members and graduate students at EES, the fellow has identified a variety of data-related challenges at different research fields of earth science, such as climate, ecology, geochemistry, geomorphology, etc. The investigation findings of the fellow also support the LTS for developing campus infrastructure for long-term data management in the sciences. Likewise, Benjamin D. Branch, the postdoctoral fellow at PUL conducted GIS (Geographic Information Systems) data curation interviews and worked closely with the GIS Information Specialist towards GIS-related instructional programs in order to recognize the data management needs in GIS research. Conceptually, the research implemented grounded theory approach of campus wide interviews for spatial GIS inquiry. To date, research analysis of a subset of 32 individual interviews with faculty, graduate students, or geospatial staff users is underway with the intent of publication. Collectively, CLIR fellowship program should work to expand the capacity and job resiliency of the library as necessary vehicle of institutional competitiveness via its prominence in data services for future consideration in the areas of data science, data curation, data rescue and collaborative support of the scientific community. In addition, the digital data service aspects of library transformation may be showcased in the results of the fellows' accomplishments.

Broadening the Participation of Native Americans in Earth Science

NASA Astrophysics Data System (ADS)

Bueno Watts, Nievita

Climate change is not a thing of the future. Indigenous people are being affected by climate changes now. Native American Earth scientists could help Native communities deal with both climate change and environmental pollution issues, but are noticeably lacking in Earth Science degree programs. The Earth Sciences produce the lowest percentage of minority scientists when compared with other science and engineering fields. Twenty semi-structured interviews were gathered from American Indian/ Alaska Native Earth Scientists and program directors who work directly with Native students to broaden participation in the field. Data was analyzed using qualitative methods and constant comparison analysis. Barriers Native students faced in this field are discussed, as well as supports which go the furthest in assisting achievement of higher education goals. Program directors give insight into building pathways and programs to encourage Native student participation and success in Earth Science degree programs. Factors which impede obtaining a college degree include financial barriers, pressures from familial obligations, and health issues. Factors which impede the decision to study Earth Science include unfamiliarity with geoscience as a field of study and career choice, the uninviting nature of Earth Science as a profession, and curriculum that is irrelevant to the practical needs of Native communities or courses which are inaccessible geographically. Factors which impede progress that are embedded in Earth Science programs include educational preparation, academic information and counseling and the prevalence of a Western scientific perspective to the exclusion of all other perspectives. Intradepartmental relationships also pose barriers to the success of some students, particularly those who are non-traditional students (53%) or women (80%). Factors which support degree completion include financial assistance, mentors and mentoring, and research experiences. Earth scientists can begin broaden participation by engaging in community-inspired research, which stems from the needs of a community and is developed in collaboration with it. Designed to be useful in meeting the needs of the community, it should include using members of the community to help gather and analyze data. These community members could be students or potential students who might be persuaded to pursue an Earth Science degree.

Manduca, C. A.

2007-12-01

Effective Earth science education depends on excellent teachers: teachers who not only possess a strong grasp of geoscience but are also well-versed in the pedagogic methods they need to connect with their audience. Preparing Earth science teachers is a task no less challenging that also requires strengths in both areas. The Teach the Earth website provides a variety of resources to support preparation of Earth science teachers. Here you can find collections of teaching activities addressing all aspects of the Earth system; discussions of teaching methods linked to examples of their use in geoscience courses; and the Earth Exploration Toolbook, a resource specifically designed for teachers who would like to incorporate data rich activities in their teaching. These resources are suitable for use by teachers, students in courses addressing the methodology of teaching Earth science and science, and faculty designing courses. Faculty working with current and future teachers will find a section on Preparing Teachers to Teach Earth Science with a collection of courses designed specifically to benefit future Earth Science teachers, examples of key activities in these courses, and descriptions of programs for pre-service and in-service teachers. The materials housed in this web-resource demonstrate a wide range of fruitful approaches and exciting opportunities. On the order of 25,000 individuals use the site repeatedly during the year. We estimate that 27 percent of these users are geoscience faculty and 12 percent are teachers. We invite teachers, faculty, researchers, and educators to enhance this resource by contributing descriptions of activities, courses, or programs as a mechanism for sharing their experience with others engaged in similar work.

Aspects of electromagnetic radiation and atomic physics needed for an understanding of astronomical applications are explored. Although intended primarily for teachers, this brochure is written so that it can be distributed to students if desired. The first section, Basic Topics, is suitable for a ninth-grade general science class; the style is simple and repetitive, and no mathematics or physics background is required. The second section, Intermediate and Advanced Topics, requires a knowledge of the material in the first section and assumes a generally higher level of achievement and motivation on the part of the student. These latter topics might fit well into junior-level physics, chemistry, or earth-science courses. Also included are a glossary, a list of references and teaching aids, class exercises, and a question and answer section.

Laser-ranging long-baseline differential atom interferometers for space

2015-12-01

High-sensitivity differential atom interferometers (AIs) are promising for precision measurements in science frontiers in space, including gravity-field mapping for Earth science studies and gravitational wave detection. Difficulties associated with implementing long-baseline differential AIs have previously included the need for a high optical power, large differential Doppler shifts, and narrow dynamic range. We propose a configuration of twin AIs connected by a laser-ranging interferometer (LRI-AI) to provide precise information of the displacements between the two AI reference mirrors and also to phase-lock the two independent interferometer lasers over long distances, thereby drastically improving the practical feasibility of long-baseline differential AI measurements. We show that a properly implemented LRI-AI can achieve equivalent functionality to the conventional differential AI measurement configuration.

NASA and the NSF, the sponsoring Federal agencies for the GLOBE Program, are seeking the participation of science teams who are working at the cutting edge of Earth systems science in large integrated Earth systems science programs. Connecting the GLOBE concept and structure with NASA and NSF's leading Earth systems science programs will give GLOBE schools and students access to top scientists, and expose them to programs that have been designated as scientific priorities. Students, teachers, parents, and their communities will be able to see how scientists of many disciplines work together to learn about the Earth system. The GLOBE solicitation released by the NSF targets partnerships between GLOBE and NSF/NASA-funded integrated Earth systems science programs. This presentation will focus on the goals and requirements of the NSF solicitation. Proponents will be expected to provide ways for the GLOBE community to interact with a group of scientists from their science programs as part of a wider joint Earth systems science educational strategy (the sponsoring agencies', GLOBE's, and the proposing programs'). Teams proposing to this solicitation must demonstrate: - A focus on direct connections with major NSF Geosciences and/or Polar Programs and/or NASA Earth-Sun research programs that are related to Earth systems science; - A demonstrable benefit to GLOBE and to NSF Geosciences and/or Polar Programs or NASA Earth-Sun education goals (providing access to program researchers and data, working with GLOBE in setting up campaigns where possible, using tested GLOBE or non-GLOBE protocols to the greatest extent possible, actively participating in the wider GLOBE community including schools, among other goals); - An international component; - How the existing educational efforts of the large science program will coordinate with GLOBE; - An Earth systems science education focus, rather than a GLOBE protocol-support focus; - A rigorous evaluation and assessment component that will collaborate with the Geosciences Education assessment contractor and with the GLOBE Office's evaluation and assessment activities; and - Contact and discussions with the GLOBE Office regarding understandings of roles and responsibilities. The following link is a PDF document with full explanation of the GLOBE Program's new direction.

The Long-Wave Infrared Earth Image as a Pointing Reference for Deep-Space Optical Communications

NASA Astrophysics Data System (ADS)

Biswas, A.; Piazzolla, S.; Peterson, G.; Ortiz, G. G.; Hemmati, H.

2006-11-01

Optical communications from space require an absolute pointing reference. Whereas at near-Earth and even planetary distances out to Mars and Jupiter a laser beacon transmitted from Earth can serve as such a pointing reference, for farther distances extending to the outer reaches of the solar system, the means for meeting this requirement remains an open issue. We discuss in this article the prospects and consequences of utilizing the Earth image sensed in the long-wave infrared (LWIR) spectral band as a beacon to satisfy the absolute pointing requirements. We have used data from satellite-based thermal measurements of Earth to synthesize images at various ranges and have shown the centroiding accuracies that can be achieved with prospective LWIR image sensing arrays. The nonuniform emissivity of Earth causes a mispointing bias error term that exceeds a provisional pointing budget allocation when using simple centroiding algorithms. Other issues related to implementing thermal imaging of Earth from deep space for the purposes of providing a pointing reference are also reported.

2002-12-01

The NASA/USRA Cooperative University-based Program in Earth System Science Education (ESSE), initiated over a decade ago through NASA support, has led in the creation of a nationwide collaborative effort to bring Earth system science into the undergraduate classroom. Forty-five ESSE institutions now offer over 120 Earth system courses each year, reaching thousands of students annually with interdisciplinary content. Through the course offerings by faculty from different disciplines and the organizational infrastructure of colleges and universities emphasizing cross disciplinary curricula, programs, degrees and departments, the ESSE Program has led in systemic change in the offering of a holistic view of Earth system science in the classroom. Building on this successful experience and collaborative infrastructure within and among colleges, universities and NASA partners, an expanded program called ESSE 21 is being supported by NASA to extend the legacy established during the last decade. Through its expanded focus including partnerships with under represented colleges and universities, the Program seeks to further develop broadly based educational resources, including shared courses, electronic learning materials and degree programs that will extend Earth system science concepts in both undergraduate and graduate classrooms and laboratories. These resources emphasizing fundamentals of Earth system science advance the nation's broader agenda for improving science, technology, engineering and mathematics competency. Overall the thrust within the classrooms of colleges and universities is critical to extending and solidifying courses of study in Earth system and global change science. ESSE 21 solicits proposals from undergraduate institutions to create or adopt undergraduate and graduate level Earth system science content in courses, curricula and degree programs. The goal for all is to effect systemic change through developing Earth system science learning materials, courses, curricula, minors or degree tracks, and programs or departments that are self-sustaining in the coming decades. Interdisciplinary college and university teams are competitively selected through a peer-reviewed Call for Participation. ESSE 21 offers an infrastructure for an interactive community of educators and researchers including under represented participants that develops interdisciplinary Earth system science content utilizing NASA resources involving global change data, models, visualizations and electronic media and networks. The Program provides for evaluation and assessment guides to help assure the pedagogical effectiveness of materials developed. The ultimate aim of ESSE 21 is to expand and accelerate the nation's realization of sound, scientific interdisciplinary educational resources for informed learning and decision-making by all from the perspective of sustainability of the Earth as a system.

Software tools and e-infrastructure services to support the long term preservation of earth science data - new functionality from the SCIDIP-ES project

The ability to preserve earth science data for the long-term is a key requirement to support on-going research and collaboration within and between earth science disciplines. A number of critically important current research initiatives (e.g. understanding climate change or ensuring sustainability of natural resources) typically rely on the continuous availability of data collected over several decades in a form which can be easily accessed and used by scientists. In many earth science disciplines the capture of key observational data may be difficult or even impossible to repeat. For example, a specific geological exposure or subsurface borehole may be only temporarily available, and earth observation data derived from a particular satellite mission is often unique. Another key driver for long-term data preservation is that the grand challenges of the kind described above frequently involve cross-disciplinary research utilising raw and interpreted data from a number of related earth science disciplines. Adopting effective data preservation strategies supports this requirement for interoperability as well as ensuring long term usability of earth science data, and has the added potential for stimulating innovative earth science research. The EU-funded SCIDIP-ES project seeks to address these challenges by developing a Europe-wide e-infrastructure for long-term data preservation by providing appropriate software tools and infrastructure services to enable and promote long-term preservation of earth science data. This poster will describe the current status of this e-infrastructure and outline the integration of the prototype SCIDIP-ES software components into the existing systems used by earth science archives and data providers. These prototypes utilise a system architecture which stores preservation information in a standardised OAIS-compliant way, and connects and adds value to existing earth science archives. A SCIDIP-ES test-bed has been implemented by the National Geoscience Data Centre (NGDC) and the British Atmospheric Data Centre (BADC) in the UK, which allows datasets to be more easily integrated and preserved for future use. Many of the data preservation requirements of these two key Natural Environment Research Council (NERC) data centres are common to other earth science data providers and are therefore more widely applicable. The capability for interoperability between datasets stored in different formats is a common requirement for the long-term preservation of data, and the way in which this is supported by the SCIDIP-ES tools and services will be explained.

The School of Ocean and Earth Sciences and Technology (SOEST) at the University of Hawaii at Manoa is home to twelve diverse research institutes, programs and academic departments that focus on a wide range of earth and planetary sciences. SOEST's main outreach goals at the K-12 level are to increase the awareness of Hawaii's schoolchildren regarding earth, ocean, and space science, and to inspire them to consider a career in science. Education and public outreach efforts in SOEST include a variety of programs that engage students and the public in formal as well as informal educational settings, such as our biennial Open House, expedition web sites, Hawaii Ocean Science Bowl, museum exhibits, and programs with local schools. Some of the projects that allow for scientist involvement in E/PO include visiting local classrooms, volunteering in our outreach programs, submitting lessons and media files to our educational database of outreach materials relating to earth and space science research in Hawaii, developing E/PO materials to supplement research grants, and working with local museum staff as science experts.

Saito, Akinori; Yoshida, Daiki; Odagi, Yoko; Takahashi, Midori; Tsugawa, Takuya; Kumano, Yoshisuke

We developed an educational program of space science data and science data observed from the space using a digital globe system, Dagik Earth. Dagik Earth is a simple and affordable four dimensional (three dimension in space and one dimension in time) presentation system. The educational program using Dagik Earth has been carried out in classrooms of schools, science museums, and research institutes to show the scientific data of the earth and planets in an intuitive way. We are developing the hardware system, data contents, and education manuals in cooperation with teachers, museum staffs and scientists. The size of the globe used in this system is from 15cm to 2m in diameter. It is selected according to the environment of the presentation. The contents cover the space science, such as aurora and geomagnetic field, the earth science, such as global clouds and earthquakes, and planetary science. Several model class plans are ready to be used in high school and junior high school. In public outreach programs of universities, research institutes, and scientific meetings, special programs have been carried out. We are establishing a community to use and develop this program for the space science education.

This study reports on the performance of electrochemical-based low-cost sensors and their use in a community application. CairClip sensors were collocated with federal reference and equivalent methods and operated in a network of sites by citizen scientists (community members) in Houston, Texas and Denver, Colorado, under the umbrella of the NASA-led DISCOVER-AQ Earth Venture Mission. Measurements were focused on ozone (O₃) and nitrogen dioxide (NO₂). The performance evaluation showed that the CairClip O₃/NO₂ sensor provided a consistent measurement response to that of reference monitors (r² = 0.79 in Houston; r² = 0.72 in Denver) whereas the CairClip NO₂ sensor measurements showed no agreement to reference measurements. The CairClip O₃/NO₂ sensor data from the citizen science sites compared favorably to measurements at nearby reference monitoring sites. This study provides important information on data quality from low-cost sensor technologies and is one of few studies that reports sensor data collected directly by citizen scientists.

Defining Top-of-Atmosphere Flux Reference Level for Earth Radiation Budget Studies

NASA Technical Reports Server (NTRS)

Loeb, N. G.; Kato, S.; Wielicki, B. A.

2002-01-01

To estimate the earth's radiation budget at the top of the atmosphere (TOA) from satellite-measured radiances, it is necessary to account for the finite geometry of the earth and recognize that the earth is a solid body surrounded by a translucent atmosphere of finite thickness that attenuates solar radiation differently at different heights. As a result, in order to account for all of the reflected solar and emitted thermal radiation from the planet by direct integration of satellite-measured radiances, the measurement viewing geometry must be defined at a reference level well above the earth s surface (e.g., 100 km). This ensures that all radiation contributions, including radiation escaping the planet along slant paths above the earth s tangent point, are accounted for. By using a field-of- view (FOV) reference level that is too low (such as the surface reference level), TOA fluxes for most scene types are systematically underestimated by 1-2 W/sq m. In addition, since TOA flux represents a flow of radiant energy per unit area, and varies with distance from the earth according to the inverse-square law, a reference level is also needed to define satellite-based TOA fluxes. From theoretical radiative transfer calculations using a model that accounts for spherical geometry, the optimal reference level for defining TOA fluxes in radiation budget studies for the earth is estimated to be approximately 20 km. At this reference level, there is no need to explicitly account for horizontal transmission of solar radiation through the atmosphere in the earth radiation budget calculation. In this context, therefore, the 20-km reference level corresponds to the effective radiative top of atmosphere for the planet. Although the optimal flux reference level depends slightly on scene type due to differences in effective transmission of solar radiation with cloud height, the difference in flux caused by neglecting the scene-type dependence is less than 0.1%. If an inappropriate TOA flux reference level is used to define satellite TOA fluxes, and horizontal transmission of solar radiation through the planet is not accounted for in the radiation budget equation, systematic errors in net flux of up to 8 W/sq m can result. Since climate models generally use a plane-parallel model approximation to estimate TOA fluxes and the earth radiation budget, they implicitly assume zero horizontal transmission of solar radiation in the radiation budget equation, and do not need to specify a flux reference level. By defining satellite-based TOA flux estimates at a 20-km flux reference level, comparisons with plane-parallel climate model calculations are simplified since there is no need to explicitly correct plane-parallel climate model fluxes for horizontal transmission of solar radiation through a finite earth.

The EarthScope Program (www.earthscope.org) funded by the National Science Foundation, fosters interdisciplinary exploration of the geologic structure and evolution of the North American continent by means of seismology, geodesy, magnetotellurics, in-situ fault-zone sampling, geochronology, and high-resolution topographic measurements. Data and findings from EarthScope continue to transform geoscientific studies throughout the Earth, enhance understanding and mitigation of hazards, and inform applications of geoscience toward environmental sustainability. The EarthScope Program also marshals significant resources and opportunities for education and outreach (E&O) in the Earth system sciences. The EarthScope National Office (ESNO) at Arizona State University serves all EarthScope stakeholders, including the EarthScope Steering Committee, researchers, educators, students, and the general public. ESNO supports and promotes E&O through social media and web-hosted resources, newsletters and published articles, E&O workshops for informal educators (interpreters), assistance to grassroots K-12 STEM teacher professional development projects (typically led by EarthScope researchers), continuing education for researchers, collaborations with other Earth-science E&O providers, and biannual national conferences. The EarthScope E&O program at ESNO leads and supports wide dissemination of the data, findings, and legacy of EarthScope. Notable activities in 2013 include expansion of social-media and web-based content, two Interpretive Workshops in the eastern United States, the Great ShakeOut, the EarthScope National Meeting in Raleigh, and continuing partnerships with affiliated E&O providers. The EarthScope National Office is supported by the National Science Foundation under grants EAR-1101100 and EAR-1216301.

To better understand the different processes and interactions that govern the earth system and to determine whether recent human-induced changes could ultimately de-stabilise its dynamics, both natural system variability and the consequences of human activities have to be observed and quantified. In this context, the European Space Agency published in 2006 "The Changing Earth: New Scientific Challenges for ESA's living Planet Programme" as the main driver of ESA's new EO science strategy. The document outlines 25 major scientific challenges covering all the different aspects of the Earth system, where EO technology and ESA missions may provide a key contribution. In this context, and responding to a request from ESAC (Earth Science Advisory Committee) to enhance the ESA scientific support towards the achievement of "The Challenges", the Agency has launched the Changing Earth Science Network as an important programmatic component of the new Support To Science Element (STSE) of the Earth Observation Envelope Programme (EOEP). In this paper we summarize the objectives of this initive and provide a review of the first projects that were selected in 2009 and are now generating their first results.

Earth benefits from NASA research and technology. Life sciences applications

NASA Technical Reports Server (NTRS)

1991-01-01

This document provides a representative sampling of examples of Earth benefits in life-sciences-related applications, primarily in the area of medicine and health care, but also in agricultural productivity, environmental monitoring and safety, and the environment. This brochure is not intended as an exhaustive listing, but as an overview to acquaint the reader with the breadth of areas in which the space life sciences have, in one way or another, contributed a unique perspective to the solution of problems on Earth. Most of the examples cited were derived directly from space life sciences research and technology. Some examples resulted from other space technologies, but have found important life sciences applications on Earth. And, finally, we have included several areas in which Earth benefits are anticipated from biomedical and biological research conducted in support of future human exploration missions.

Kiely, Aaron B. (Editor); Renner, Robert L. (Editor)

1996-01-01

The sixth annual Space and Earth Science Data Compression Workshop and the third annual Data Compression Industry Workshop were held as a single combined workshop. The workshop was held April 4, 1996 in Snowbird, Utah in conjunction with the 1996 IEEE Data Compression Conference, which was held at the same location March 31 - April 3, 1996. The Space and Earth Science Data Compression sessions seek to explore opportunities for data compression to enhance the collection, analysis, and retrieval of space and earth science data. Of particular interest is data compression research that is integrated into, or has the potential to be integrated into, a particular space or earth science data information system. Preference is given to data compression research that takes into account the scien- tist's data requirements, and the constraints imposed by the data collection, transmission, distribution and archival systems.

2004-12-01

The Earth Institute has received a major NSF ADVANCE grant targeted at increasing the participation and advancement of women scientists and engineers in the Academy through institutional transformation. The Earth Institute at Columbia University includes 9 research institutes including Lamont-Doherty Earth Observatory, Center for Environmental Research and Conservation (CERC), Center for International Earth Science Information Network (CIESIN), International Research Institute (IRI) for Climate Prediction, Earth Engineering Center, NASA-Goddard Institute for Space Studies, Center for Risks and Hazards, Center for Globalization and Sustainable Development, and Center for Global Health and Economic Development and six academic departments including Ecology, Evolution and Environmental Biology (E3B, School of Arts and Sciences), Earth and Environmental Engineering (DEEE, School of Engineering and Applied Sciences), Department of Environmental Health (School of Public Health), Department of Earth and Environmental Sciences (DEES, School of Arts and Sciences), Department of International and Public Affairs (School of International and Policy Affairs), and Barnard College Department of Environmental Science. The Earth Institute at Columbia University's ADVANCE program is based both on a study of the status of women at Columbia and research on the progression of women in science elsewhere. The five major targets of the Columbia ADVANCE program are to (1) change the demographics of the faculty through intelligent hiring practices, (2) provide support to women scientists through difficult life transitions including elder care and adoption or birth of a child, (3) enhance mentoring and networking opportunities, (4) implement transparent promotion procedures and policies, and (5) conduct an institutional self study. The Earth Institute ADVANCE program is unique in that it addresses issues that tend to manifest themselves in the earth and environmental fields, such as extended field programs, which lay the foundation for leadership positions, but which may be difficult for young faculty. The strategy is to use the Earth Institute as a test bed for institutional change, and then expand the successful programs to other Columbia Science and Engineering Departments, as appropriate. Columbia's administration is committed to changing policies and supporting successful programs beyond the completion of the NSF grant. Earth Institute ADVANCE programs include (a) a self study including a climate survey modeled after the 1999 MIT study, (b) a senior faculty working group that will facilitate recruitment and retention by providing support for searches, faculty development, and retention, (c) internal funding competitions designed to recruit and retain women scientists and engineers, and (d) focused workshops and conferences. The ADVANCE program will establish offices both on the Morningside campus in Manhattan and Lamont campus in Palisades, NY.

Spherical versus flat displays for communicating climate science concepts through stories

NASA Astrophysics Data System (ADS)

Schollaert Uz, S.; Storksdieck, M.; Duncan, B. N.

2016-12-01

One of the most compelling ways to display global Earth science data is through spherical displays. Museums around the world use Science On a Sphere for informal education of the general public, commonly for Earth science. An increasing number of universities and K-12 school systems are acquiring spheres to support formal education curriculum, but the use of spheres in education is relatively new and understanding of their advantages and best practices is still evolving. Many museums do not have the resources to staff their sphere with a facilitator or they have high turn-over of volunteer facilitators without a science background. Many K-12 teachers lack resources or training needed to utilize sphere technology to address global phenomena or Earth system science. One solution to this "facilitator-problem" has been the creation of "canned shows" for spheres, like ClimateBits. These are short videos that help people visualize Earth science concepts through global data sets and simple story-telling. To understand whether and when data driven story-telling works best on a sphere, we surveyed groups that saw identical Earth system science stories presented on a spherical display versus a flat screen. We also surveyed identical groups using live Earth science data story-telling compared to the ClimateBits videos. Some of the advantages of each format were most apparent in the qualitative comments at the end of the surveys

On the global geodetic observing system: Africa's preparedness and challenges

NASA Astrophysics Data System (ADS)

Botai, O. J.; Combrinck, Ludwig; Rautenbach, C. J. Hannes

2013-02-01

Space geodetic techniques and satellite missions play a crucial role in the determination and monitoring of geo-kinematics, Earth's rotation and gravity fields. These three pillars of geodesy provide the basis for determining the geodetic reference frames with high accuracy, spatial resolution and temporal stability. Space geodetic techniques have been used for the assessment of geo-hazards, anthropogenic hazards and in the design of early warning systems for hazard and disasters. In general, space geodesy provides products for Earth observation, science and influences many activities (e.g., building and management) in a modern society. In order to further promote the application of space geodetic methods to solving Earth science problems, the Global Geodetic Observing System (GGOS) of the International Association of Geodesy (IAG) was commissioned as an important geodetic infrastructure that integrates different geodetic techniques (such as Global Navigation Satellite Systems, Very Long Baseline Interferometry, Satellite Laser Ranging, Interferometric Synthetic Aperture Radar and Doppler Orbitography and Radio-positioning Integrated by Satellite), models and analysis techniques for the purpose of ensuring long-term, precise monitoring of geodetic observables vital for monitoring Earth system processes. Since its inception, there has been considerable progress made towards setting up the infrastructure necessary for the establishment of the GGOS database. While the challenges that beleaguer the GGOS are acknowledged (at least at global level), the assessment of an attuned GGOS infrastructure in the African context is necessary, yet lacking. In the present contribution, (a) the African preparedness and response to the observing system is assessed, and (b) the specific scientific and technological challenges of establishing a regional GGOS hub for Africa are reviewed. Currently only South Africa has a fundamental geodetic observatory located at Hartebeesthoek, Pretoria. Other countries in Africa have shown interest to participate in global geodetic activities, in particular through interest in the development of a unified African geodetic reference frame (AFREF). In particular interest has been shown in the proposed African VLBI Network (AVN), which will be partially based on existing ex-telecommunication radio antennas. Several countries are investigating their participation in the AVN, including Kenya, Nigeria and Ghana.

The impact of socio-political environment on the perception of science - a comparative study of German and Israeli approaches to science education

NASA Astrophysics Data System (ADS)

Schneider, S.; Rabinowitz, D.

2017-12-01

At the interface of environmental anthropology, social science, education research, and Earth Sciences, this presentation will look at Earth science education in school and out-of-school settings in Germany and Israel. We will focus on divergent cultural concepts of nature and science within the four-columned societal system in Israel: the secular Israeli community, which is oriented on western standards and concepts, the orthodox community with a stronger focus on merging scientific and religious approaches to understanding the Earth system, the Arabian community in Israel, which is strongly influenced by the Arabian science tradition as well as by confined monetary resources, and the ultra-orthodox community where science education seems to be totally abandoned in favor of Thora-studies. These environments, alongside a more homogeneous Germany educational system, resample an experimental setting with differences in a manageable number of parameters. We will analyze educational material used by the different communities in terms of the presented functions and services of the Earth sciences as well as in respect to the image of Earth sciences constructed by educational material of the observed communities. The aim of this project is to look for evidence that allows to attribute significant differences in education concepts to formal socio-political settings in the observed communities. The term Socio-political environment as used in this project proposal describes the context that is predetermined by cultural, political, and religious traditions. It described the pre-conditions in which communication takes place. Within this presentation, we will discuss the concept of socio-political environments. One of our hypothesis is, that the intensity of differences in Earth science community will be associated with differences in the socio-political environment. Influences of cultural, political, and religious boundary conditions will provide an insight into alterations within the effectiveness of standardized education and communication concepts. Similar observations where recently made in analyzing the media representation of Earth science research in respect to parameters from structural geology. These findings demand for similar analysis in respect to Earth science education as well.

The spacelab scientific missions: A comprehensive bibliography of scientific publications

November 1993 represented the 10-year anniversary of the flight of Spacelab 1 mission, with the first precursor mission (OSTA-1) being launched 2 years earlier. Since that time, a total of 27 Shuttle missions has been flown, using the Spacelab system as a facility for conducting scientific research in space. The missions flown to date have allowed a total of approximately 500 Principle Investigator class investigations to be conducted in orbit. These investigations have constituted major scientific efforts in astronomy/astrophysics, atmospheric science, Earth observation, life sciences, microgravity science, and space plasma physics. An initial survey of the scientific products gleaned from Spacelab missions already flown was sent to the Principle Investigators. In that survey, information was gathered from the investigators on the scientific highlights of their investigations and statistical measurements of overall success -- such as papers published. This document is a compilation of the papers that have been published to date in referred literature.

Using the Earth as an Effective Model for Integrating Space Science Into Education Outreach Programs

Our methods of teaching Earth and space science as two disciplines do not represent the spirit of earlier scientists such as Aristotle, da Vinci, and Galileo. We need to re-evaluate these methods and take advantage of the excitement created in the general public over the recent space science exploration programs. The information that we are obtaining from both the Mars missions and Cassini-Huygens focuses on interpreting geomorphology, mineral compositions and gas identification based on Earth as a baseline for data evaluation. This type of evaluation is an extension of Hutton's 18th century principle of Uniformitarianism, the present is the key to the past, or Earth is the key for understanding extraterrestrial bodies. Geomorphological examples are volcanic activity, meteoritic impacts, and evidence of water altering surface features. The Hawaiian, or shield, type volcanoes are analogues for Olympus Mons and the other volcanoes on Mars. Other examples include comparing sand dunes on Earth with possible Martian dunes, known stream patterns on Earth with potential stream patterns on Mars, and even comparing meteoritic impact features on Mars, the Earth, Moon and Mercury. All of these comparisons have been developed into inquiry-based activities and are available through NASA publications. Each of these activities is easily adapted to emphasize either Earth science or space science or both. Beyond geomorphology, solar storms are an excellent topic for integrating Earth and space science. Solar storms are traditionally part of space science studies, but most students do not understand their effect on Earth or the intense effects they could have on humans, whether traveling through space or exploring the surfaces of the Moon or Mars. Effects are not only limited to space travel and other planetary surfaces but also include Earth's magnetosphere, which in turn, affect radio transmission and potentially climate. Like geomorphology courses, there are extensive NASA programs available via either the Internet or CD (e.g., those distributed by P. Reiff, Rice University) that provide inquiry-based activities for students. There is great potential to share the connections of Earth and space science by using NASA developed education materials. The materials can be adapted for the classroom, after school programs, family outreach events, and summer science enrichment programs.

The inclusion of Science Technology Society topics in junior high school earth science textbooks

NASA Astrophysics Data System (ADS)

Fadhli, Fathi Ali

2000-10-01

The Science Technology Society (STS) approach is a major science education reform through which a scientifically literate citizen could be produced. The teaching of science through STS approach is centered on science and technology related issues and problems. The purpose of this study was to analyze five earth science textbooks published in the 1990's for their inclusion of twelve sciences and technology related issues and problems and for their inclusion of activities focused on STS. The selected earth science textbooks were; Scott Foresman, Heath, Holt, Merrill and Prentice-Hall. The targeted twelve issues and problems were identified by Bybee (1987), as the most important global science and technology related issues and problems. The numbers of full text pages devoted to each topic were determined by classifying each segment to one of the targeted topics. In addition, the numbers of STS activities were also determined by using criteria developed for this study. ANOVA statistical analyses and t-tests showed that the analyzed earth science textbooks treated the studied STS issues and problems and treated the STS activities differently. It was found that six of the studied issues and problems were constantly receiving more attention in all the analyzed earth science textbooks than the rest of the topics. These topics were; Air Quality and Atmosphere, Energy Shortages, Water Resources, Land Use, Hazardous Substances, and Mineral Resources. The overall results revealed that only an average of 8.82% of the text pages in all the analyzed earth science textbooks were devoted to STS topics and 5.49% of the activities in all the analyzed earth science textbooks were focused on STS topics. However, none of the activities focused on STS topics were presented in STS approach as defined by NSTA. The percentage of STS topics inclusion and the percentage of activities focused on STS topics were considered to be very low. Accordingly, the objectives and goals of STS approach will not be achieved through using the analyzed earth science textbooks. The low percentages of STS activities and topics indicated also that the STS approach would not be fairly presented in science classrooms as long as science teachers depend on science textbooks 90% of their teaching time. Moreover, the results of this study revealed also that the inclusion of STS approach in science textbooks is still considered to be very low despite the support provided to the STS approach by science teachers, educators, organizations, and education departments and also despite of the publishing of Project Syntheses (1977) since twenty eight years ago.

Studying, understanding and modelling global change require geodetic reference frames with an order of accuracy higher than the magnitude of the effects to be actually studied and with high consistency and reliability worldwide. The International Association of Geodesy, taking care of providing a precise geodetic infrastructure for monitoring the Earth system, promotes the implementation of an integrated global geodetic reference frame that provides a reliable frame for consistent analysis and modelling of global phenomena and processes affecting the Earth's gravity field, the Earth's surface geometry and the Earth's rotation. The definition, realization, maintenance and wide utilization of the International Terrestrial Reference System guarantee a globally unified geometric reference frame with an accuracy at the millimetre level. An equivalent high-precision global physical reference frame that supports the reliable description of changes in the Earth's gravity field (such as sea level variations, mass displacements, processes associated with geophysical fluids) is missing. This paper addresses the theoretical foundations supporting the implementation of such a physical reference surface in terms of an International Height Reference System and provides guidance for the coming activities required for the practical and sustainable realization of this system. Based on conceptual approaches of physical geodesy, the requirements for a unified global height reference system are derived. In accordance with the practice, its realization as the International Height Reference Frame is designed. Further steps for the implementation are also proposed.

Virtual Collections: An Earth Science Data Curation Service

2016-12-01

The role of Earth science data centers has traditionally been to maintain central archives that serve openly available Earth observation data. However, in order to ensure data are as useful as possible to a diverse user community, Earth science data centers must move beyond simply serving as an archive to offering innovative data services to user communities. A virtual collection, the end product of a curation activity that searches, selects, and synthesizes diffuse data and information resources around a specific topic or event, is a data curation service that improves the discoverability, accessibility and usability of Earth science data and also supports the needs of unanticipated users. Virtual collections minimize the amount of time and effort needed to begin research by maximizing certainty of reward and by providing a trustworthy source of data for unanticipated users. This presentation will define a virtual collection in the context of an Earth science data center and will highlight a virtual collection case study created at the Global Hydrology Resource Center data center.

The role of networking in student and early career years is critical in the development of international interdisciplinary earth system science. These networks - both peer and mentor-based - can build community, foster enthusiasm and further research applications in addition to the traditional goal of identifying and obtaining work. UNESCO has nearly 40 years of experience in building international research teams through the International Geoscience Program (IGCP) and has recently focused their attention on the status of the earth sciences in Africa. UNESCO’s Earth Science Education Initiative in Africa ran a series of regional scoping workshops around the continent in order to develop an integrated status report on the earth sciences in Africa. The results, which are globally relevant, indicate that the field is limited by the level of basic science education of incoming students and restricted laboratory facilities, but also by a lack of connectedness. This isolation relates both to the interaction between researchers within countries and around the world but also the divide between Universities and Industry and the failure of the field to communicate its relevance to the public. In a context where livelihood opportunities are the driver of study and the earth sciences provide a major source of income, practical academic ties to industry are an essential element of the attractiveness of the field to students. Actions and ideas for addressing this situation will be presented to reinforce the role of the earth sciences in improving human and environmental well-being.

One of the three strategic goals of NASA is to Advance understanding of Earth and develop technologies to improve the quality of life on our home planet (NASA strategic plan 2014). NASA's Earth Science Data System (ESDS) Program directly supports this goal. NASA has been launching satellites for civilian Earth observations for over 40 years, and collecting data from various types of instruments. Especially since 1990, with the start of the Earth Observing System (EOS) Program, which was a part of the Mission to Planet Earth, the observations have been significantly more extensive in their volumes, variety and velocity. Frequent, global observations are made in support of Earth system science. An open data policy has been in effect since 1990, with no period of exclusive access and non-discriminatory access to data, free of charge. NASA currently holds nearly 10 petabytes of Earth science data including satellite, air-borne, and ground-based measurements and derived geophysical parameter products in digital form. Millions of users around the world are using NASA data for Earth science research and applications. In 2014, over a billion data files were downloaded by users from NASAs EOS Data and Information System (EOSDIS), a system with 12 Distributed Active Archive Centers (DAACs) across the U. S. As a core component of the ESDS Program, EOSDIS has been operating since 1994, and has been evolving continuously with advances in information technology. The ESDS Program influences as well as benefits from advances in Earth Science Informatics. The presentation will provide an overview of the role and evolution of NASAs ESDS Program.

Clune, T.; Seablom, M. S.; Moe, K.

2012-12-01

The NASA Earth Science Technology Office (ESTO) regularly makes investments for nurturing advanced concepts in information technology to enable rapid, low-cost acquisition, processing and visualization of Earth science data in support of future NASA missions and climate change research. In 2012, the National Research Council published a mid-term assessment of the 2007 decadal survey for future spacemissions supporting Earth science and applications [1]. The report stated, "Earth sciences have advanced significantly because of existing observational capabilities and the fruit of past investments, along with advances in data and information systems, computer science, and enabling technologies." The report found that NASA had responded favorably and aggressively to the decadal survey and noted the role of the recent ESTO solicitation for information systems technologies that partnered with the NASA Applied Sciences Program to support the transition into operations. NASA's future missions are key stakeholders for the ESTO technology investments. Also driving these investments is the need for the Agency to properly address questions regarding the prediction, adaptation, and eventual mitigation of climate change. The Earth Science Division has championed interdisciplinary research, recognizing that the Earth must be studied as a complete system in order toaddress key science questions [2]. Information technology investments in the low-mid technology readiness level (TRL) range play a key role in meeting these challenges. ESTO's Advanced Information Systems Technology (AIST) program invests in higher risk / higher reward technologies that solve the most challenging problems of the information processing chain. This includes the space segment, where the information pipeline begins, to the end user, where knowledge is ultimatelyadvanced. The objectives of the program are to reduce the risk, cost, size, and development time of Earth Science space-based and ground-based systems, increase the accessibility and utility of science data, and to enable new observation measurements and information products. We will discuss the ESTO investment strategy for information technology development, the methods used to assess stakeholder needs and technology advancements, and technology partnerships to enhance the infusion for the resulting technology.

2004-12-01

The Earth and Space sciences are truly global in nature and encompass the most diverse subject areas in science. Yet, the practitioners of these fields do not reflect the diversity of the populations that are impacted by the outcomes of the research in these fields of study. The global marketplace, migration, the search for economic and renewable resources, Earth Systems research, and understanding our place in the universe compels us to be more inclusive of the populations and cultures that inhabit our planet. In this talk, we discuss the relevancy of these issues on scientific endeavors in the 21st century and the need for the Earth and Space sciences to be the leaders within the broad scientific community of ensuring that science remains an inclusive enterprise.

Propellantless AOCS Design for a 160-m, 450-kg Sailcraft of the Solar Polar Imager Mission

NASA Technical Reports Server (NTRS)

Wie, Bong; Thomas, Stephanie; Paluszek, Michael; Murphy, David

2005-01-01

An attitude and orbit control system (AOCS) is developed for a 160-m, 450-kg solar sail spacecraft of the Solar Polar Imager (SPI) mission. The SPI mission is one of several Sun- Earth Connections solar sail roadmap missions currently envisioned by NASA. A reference SPI sailcraft consists of a 160-m, 150-kg square solar sail, a 250-kg spacecraft bus, and 50-kg science payloads, The 160-m reference sailcraft has a nominal solar thrust force of 160 mN (at 1 AU), an uncertain center-of-mass/center-of-pressure offset of +/- 0.4 m, and a characteristic acceleration of 0.35 mm/sq s. The solar sail is to be deployed after being placed into an earth escaping orbit by a conventional launch vehicle such as a Delta 11. The SPI sailcraft first spirals inwards from 1 AU to a heliocentric circular orbit at 0.48 AU, followed by a cranking orbit phase to achieve a science mission orbit at a 75-deg inclination, over a total sailing time of 6.6 yr. The solar sail will be jettisoned after achieving the science mission orbit. This paper focuses on the solar sailing phase of the SPI mission, with emphasis on the design of a reference AOCS consisting of a propellantless primary ACS and a microthruster-based secondary (optional) ACS. The primary ACS employs trim control masses running along mast lanyards for pitch/yaw control together with roll stabilizer bars at the mast tips for quadrant tilt (roll) control. The robustness and effectiveness of such a propellantless primary ACS would be enhanced by the secondary ACS which employs tip-mounted, lightweight pulsed plasma thrusters (PPTs). The microPPT-based ACS is mainly intended for attitude recovery maneuvers from off-nominal conditions. A relatively fast, 70-deg pitch reorientation within 3 hrs every half orbit during the orbit cranking phase is shown to be feasible, with the primary ACS, for possible solar observations even during the 5-yr cranking orbit phase.

In order to maximize the public's awareness of earth science observations, earth science data must be available in multiple media formats. This talk will focus on the use High Definition TV format in presenting earth science data, The Television (HDTV) networks are mandated to completely switch over from the current TV standard (NTSC) to HDTV in the next seven years. Museums are also beginning to use HDTV format in their displays. The Visualization Analysis Laboratory at Goddard Space Flight Center has been experimenting with the use of HDTV to present earth science data. The experimental package we have developed is called the Electronic Theater (e-theater). The e-theater is a mobile presentation system used for displaying and teaching groups about earth science and the delicate interdependence between the various earth systems. The e-theater takes advantage of a double-wide screen to show the audiences high resolution data displays. The unique architecture used in this exhibit allows several data sets to be displayed at one time, demonstrating the connections between different earth systems. The data animations are manipulated in real-time during the presentation and can be paused, moved forward, backward, looped, or zoomed into, to maximize the flexibility of the presentation. Because HDTV format is used within the e-theater, the materials generated for the e-theater are made available to the news media and museums.

Kempler, Steven

2014-01-01

What Exactly do Earth Data Scientists do, and What do They Need to Know, to do It? There is not one simple answer, but there are many complex answers. Data Science, and data analytics, are new and nebulas, and takes on different characteristics depending on: The subject matter being analyzed, the maturity of the research, and whether the employed subject specific analytics is descriptive, diagnostic, discoveritive, predictive, or prescriptive, in nature. In addition, in a, thus far, business driven paradigm shift, university curriculums teaching data analytics pertaining to Earth science have, as a whole, lagged behind, andor have varied in approach.This presentation attempts to breakdown and identify the many activities that Earth Data Scientists, as a profession, encounter, as well as provide case studies of specific Earth Data Scientist and data analytics efforts. I will also address the educational preparation, that best equips future Earth Data Scientists, needed to further Earth science heterogeneous data research and applications analysis. The goal of this presentation is to describe the actual need for Earth Data Scientists and the practical skills to perform Earth science data analytics, thus hoping to initiate discussion addressing a baseline set of needed expertise for educating future Earth Data Scientists.

NASA's Earth Science Program is dedicated to advancing Earth remote sensing and pioneering the scientific use of satellite measurements to improve human understanding of our home planet. Through the MEaSUREs Program, NASA is continuing its commitment to expand understanding of the Earth system using consistent data records. Emphasis is on linking together multiple data sources to form coherent time-series, and facilitating the use of extensive data in the development of comprehensive Earth system models. A primary focus of the MEaSUREs Program is the creation of Earth System Data Records (ESDRs). An ESDR is defined as a unified and coherent set of observations of a given parameter of the Earth system, which is optimized to meet specific requirements for addressing science questions. These records are critical for understanding Earth System processes; for the assessment of variability, long-term trends, and change in the Earth System; and for providing input and validation means to modeling efforts. Seven MEaSUREs projects will be archived and distributed through services at the Goddard Earth Sciences Data and Information Services Center (GES DISC).

In this photo, the Gravity Probe B (GP-B) space vehicle is completed during the solar array installation. The GP-B is the relativity experiment developed at Stanford University to test two extraordinary predictions of Albert Einstein’s general theory of relativity. The experiment will measure, very precisely, the expected tiny changes in the direction of the spin axes of four gyroscopes contained in an Earth-orbiting satellite at a 400-mile altitude. So free are the gyroscopes from disturbance that they will provide an almost perfect space-time reference system. They will measure how space and time are very slightly warped by the presence of the Earth, and, more profoundly, how the Earth’s rotation very slightly drags space-time around with it. These effects, though small for the Earth, have far-reaching implications for the nature of matter and the structure of the Universe. GP-B is among the most thoroughly researched programs ever undertaken by NASA. This is the story of a scientific quest in which physicists and engineers have collaborated closely over many years. Inspired by their quest, they have invented a whole range of technologies that are already enlivening other branches of science and engineering. GP-B is scheduled for launch in April 2004 and managed for NASA by the Marshall Space Flight Center. Development of the GP-B is the responsibility of Stanford University along with major subcontractor Lockheed Martin Corporation. (Image credit to Russ Underwood, Lockheed Martin Corporation).

Solar Electric Propulsion for Primitive Body Science Missions

NASA Technical Reports Server (NTRS)

Witzberger, Kevin E.

2006-01-01

This paper describes work that assesses the performance of solar electric propulsion (SEP) for three different primitive body science missions: 1) Comet Rendezvous 2) Comet Surface Sample Return (CSSR), and 3) a Trojan asteroid/Centaur object Reconnaissance Flyby. Each of these missions launches from Earth between 2010 and 2016. Beginning-of-life (BOL) solar array power (referenced at 1 A.U.) varies from 10 to 18 kW. Launch vehicle selections range from a Delta II to a Delta IV medium-class. The primary figure of merit (FOM) is net delivered mass (NDM). This analysis considers the effects of imposing various mission constraints on the Comet Rendezvous and CSSR missions. Specifically, the Comet Rendezvous mission analysis examines an arrival date constraint with a launch year variation, whereas the CSSR mission analysis investigates an Earth entry velocity constraint commensurate with past and current missions. Additionally, the CSSR mission analysis establishes NASA's New Frontiers (NF) Design Reference Mission (DRM) in order to evaluate current and future SEP technologies. The results show that transfer times range from 5 to 9 years (depending on the mission). More importantly, the spacecraft's primary propulsion system performs an average 5-degree plane change on the return leg of the CSSR mission to meet the previously mentioned Earth entry velocity constraint. Consequently, these analyses show that SEP technologies that have higher thrust-to-power ratios can: 1) reduce flight time, and 2) change planes more efficiently.

PANGAEA® - Data Publisher for Earth & Environmental Science - Research data enters scholarly communication and big data analysis

NASA Astrophysics Data System (ADS)

Diepenbroek, Michael; Schindler, Uwe; Riedel, Morris; Huber, Robert

2014-05-01

The ISCU World Data Center PANGAEA is an information system for acquisition, processing, long term storage, and publication of geo-referenced data related to earth science fields. Storing more than 350.000 data sets from all fields of geosciences it belongs to the largest archives for observational earth science data. Standard conform interfaces (ISO, OGC, W3C, OAI) enable access from a variety of data and information portals, among them the search engine of PANGAEA itself ((www.pangaea.de) and e.g. GBIF. All data sets in PANGAEA are citable, fully documented, and can be referenced via persistent identifiers (Digital Object Identifier - DOI) - a premise for data publication. Together with other ICSU World Data Centers (www.icsu-wds.org) and the Technical Information Library in Germany (TIB) PANGAEA had a share in the implementation of a DOI based registry for scientific data, which by now is supported by a worldwide consortium of libraries (www.datacite.org). A further milestone was building up strong co-operations with science publishers as Elsevier, Springer, Wiley, AGU, Nature and others. A common web service allows to reference supplementary data in PANGAEA directly from an articles abstract page (e.g. Science Direct). The next step with science publishers is to further integrate the editorial process for the publication of supplementary data with the publication procedures on the journal side. Data centric research efforts such as environmental modelling or big data analysing approaches represent new challenges for PANGAEA. Integrated data warehouse technologies are used for highly efficient retrievals and compilations of time slices or surface data matrixes on any measurement parameters out of the whole data continuum. Further, new and emerging big data approaches are currently investigated within PANGAEA to e.g. evaluate its usability for quality control or data clustering. PANGAEA is operated as a joint long term facility by MARUM at the University Bremen and the Alfred Wegener Institute for Polar and Marine Research (AWI). More than 80% of the funding results from project data management and the implementation of spatial data infrastructures (more than 160 International to national projects since the last 15 years - www.pangaea.de/projects).

Overview of the Mission Design Reference Trajectory for NASA's Asteroid Redirect Robotic Mission

The National Aeronautics and Space Administration's (NASA's) recently cancelled Asteroid Redirect Mission was proposed to rendezvous with and characterize a 100 m plus class near-Earth asteroid and provide the capability to capture and retrieve a boulder off of the surface of the asteroid and bring the asteroidal material back to cislunar space. Leveraging the best of NASA's science, technology, and human exploration efforts, this mission was originally conceived to support observation campaigns, advanced solar electric propulsion, and NASA's Space Launch System heavy-lift rocket and Orion crew vehicle. The asteroid characterization and capture portion of ARM was referred to as the Asteroid Redirect Robotic Mission (ARRM) and was focused on the robotic capture and then redirection of an asteroidal boulder mass from the reference target, asteroid 2008 EV5, into an orbit near the Moon, referred to as a Near Rectilinear Halo Orbit where astronauts would visit and study it. The purpose of this paper is to document the final reference trajectory of ARRM and the challenges and unique methods employed in the trajectory design of the mission.

Leveraging High Resolution Topography for Education and Outreach: Updates to OpenTopography to make EarthScope and Other Lidar Datasets more Prominent in Geoscience Education

NASA Astrophysics Data System (ADS)

Kleber, E.; Crosby, C. J.; Arrowsmith, R.; Robinson, S.; Haddad, D. E.

2013-12-01

The use of Light Detection and Ranging (lidar) derived topography has become an indispensable tool in Earth science research. The collection of high-resolution lidar topography from an airborne or terrestrial platform allows landscapes and landforms to be represented at sub-meter resolution and in three dimensions. In addition to its high value for scientific research, lidar derived topography has tremendous potential as a tool for Earth science education. Recent science education initiatives and a community call for access to research-level data make the time ripe to expose lidar data and derived data products as a teaching tool. High resolution topographic data fosters several Disciplinary Core Ideas (DCIs) of the Next Generation Science Standards (NGS, 2013), presents respective Big Ideas of the new community-driven Earth Science Literacy Initiative (ESLI, 2009), teaches to a number National Science Education Standards (NSES, 1996), and Benchmarks for Science Literacy (AAAS, 1993) for science education for undergraduate physical and environmental earth science classes. The spatial context of lidar data complements concepts like visualization, place-based learning, inquiry based teaching and active learning essential to teaching in the geosciences. As official host to EarthScope lidar datasets for tectonically active areas in the western United States, the NSF-funded OpenTopography facility provides user-friendly access to a wealth of data that is easily incorporated into Earth science educational materials. OpenTopography (www.opentopography.org), in collaboration with EarthScope, has developed education and outreach activities to foster teacher, student and researcher utilization of lidar data. These educational resources use lidar data coupled with free tools such as Google Earth to provide a means for students and the interested public to visualize and explore Earth's surface in an interactive manner not possible with most other remotely sensed imagery. The education section of the OpenTopography portal has recently been strengthened with the addition of several new resources and the re-organization of existing content for easy discovery. New resources include a detailed frequently asked questions (FAQ) section, updated 'How-to' videos for downloading data from OpenTopography and additional webpages aimed at students, educators and researchers leveraging existing and updated resources from OpenTopography, EarthScope and other organizations. In addition, the OpenLandform catalog, an online collection of classic geologic landforms depicted in lidar, has been updated to include additional tectonic landforms from EarthScope lidar datasets.

The Next Generation Science Standards (NGSS), due to be released in 2013, set a new direction for K-12 science education in America. These standards will put forth significant changes for Earth and space sciences. The NGSS are based upon the recommendations of the National Research Council's 2011 report "A Framework for K-12 Science Education: Practices, Cross-Cutting Concepts, and Core Ideas." The standards are being written by a large group of authors who represent many different constituencies, including 26 participating states, in a process led by Achieve, Inc. The standards encourage innovative ways to teach science at the K-12 level, including enhanced integration between the content, practices, and crosscutting ideas of science and greater assimilation among the sciences and engineering, and among the sciences, mathematics, and English language arts. The NGSS presents a greater emphasis on Earth and space sciences than in previous standards, recommending a year at both the middle and high school levels. The new standards also present a greater emphasis on areas of direct impact between humans and the Earth system, including climate change, natural hazards, resource management, and sustainability.

From Soup to Nuts: How Terra has enabled the growth of NASA Earth science communication

Ward, K.; Carlowicz, M. J.; Allen, J.; Voiland, A.; Przyborski, P.

2014-12-01

The birth of NASA's Earth Observatory website in 1999 closely mirrored the launch of Terra and over the years its growth has paralleled that of the Earth Observing System (EOS) program. With the launch of Terra, NASA gained an extraordinary platform that not only promised new science capabilities but gave us the data and imagery for telling the stories behind the science. The Earth Observatory Group was founded to communicate these stories to the public. We will present how we have used the capabilities of all the Terra instruments over the past 15 years to expand the public's knowledge of NASA Earth science. The ever-increasing quantity and quality of Terra data, combined with technological improvements to data availability and services has allowed the Earth Observatory and, as a result, the greater science-aware media, to greatly expand the visibility of NASA data and imagery. We will offer thoughts on best practices in using these multi-faceted instruments for public communication and we will share how we have worked with Terra science teams and affiliated systems to see the potential stories in their data and the value of providing the data in a timely fashion. Terra has allowed us to tell the stories of our Earth today like never before.

A Collaborative Data Scientist Framework for both Primary and Secondary Education

NASA Astrophysics Data System (ADS)

Branch, B. D.

2011-12-01

The earth science data educational pipeline may be dependent on K-20 outcomes. Thus, a challenge for earth science and space informatics education or generational knowledge transfer consideration may be a non-existing or cost prohibitive pedagogical earth science reality. Such may require a technological infrastructure, a validated assessment system, and collaboration among stakeholders of primary and secondary education. Moreover, the K-20 paradigms may engage separate science and technology preparation standards when fundamental informatics requires an integrated pedagogical approach. In simple terms, a collaborative earth science training program for a subset of disciplines may a pragmatics means for formal data scientist training that is sustainable as technology evolves and data-sharing policy becomes a norm of data literacy. As the Group Earth Observation Systems of Systems (GEOSS) has a 10-work plan, educational stakeholders may find funding avenues if government can see earth science data training as a valuable job skill and societal need. This proposed framework suggested that ontological literacy, database management and storage management and data sharing capability are fundamental informatics concepts of this proposed framework where societal engagement is incited. Here all STEM disciplines could incite an integrated approach to mature such as learning metrics in their matriculation and assessment systems. The NSF's Earth Cube and Europe's WISE may represent best cased for such framework implementation.

This paper describes the current trajectory design concept for a multiple Europa flyby mission and discusses several trajectory design challenges. The candidate reference trajectory utilizes multiple Europa flybys while around Jupiter to enable near global coverage of Europa while balancing science requirements, radiation dose, propellant usage, and flight time. Trajectory design trades and robustness are also discussed.

The current Earth observing capability depends primarily on spacecraft missions and ground-based networks to provide the critical on-going observations necessary for improved understanding of the Earth system. Aircraft missions play an important role in process studies but are limited to relatively short-duration flights. Suborbital observations have contributed to global environmental knowledge by providing in-depth, high-resolution observations that space-based and in-situ systems are challenged to provide; however, the limitations of aerial platforms - e.g., limited observing envelope, restrictions associated with crew safety and high cost of operations have restricted the suborbital program to a supporting role. For over a decade, it has been recognized that autonomous aerial observations could potentially be important. Advances in several technologies now enable autonomous aerial observation systems (AAOS) that can provide fundamentally new observational capability for Earth science and applications and thus lead scientists and engineers to rethink how suborbital assets can best contribute to Earth system science. Properly developed and integrated, these technologies will enable new Earth science and operational mission scenarios with long term persistence, higher-spatial and higher-temporal resolution at lower cost than space or ground based approaches. This paper presents the results of a science driven, systems oriented study of broad Earth science measurement needs. These needs identify aerial mission scenarios that complement and extend the current Earth Observing System. These aerial missions are analogous to space missions in their complexity and potential for providing significant data sets for Earth scientists. Mission classes are identified and presented based on science driven measurement needs in atmospheric, ocean and land studies. Also presented is a nominal concept of operations for an AAOS: an innovative set of suborbital assets that complements and augments current and planned space-based observing systems.

Dagik Earth: An affordable three-dimensional presentation of global geoscience data in classrooms and science museums

Three-dimensional display of the Earth is a most effective way to impress audiences how the Earth looks and make them understand the Earth is one system. There are several projects to display global data on 3D globes, such as Science on a Sphere by NOAA and Geo Cosmos by Miraikan, Japan. They have made great successes to provide audiences opportunities to learn the geoscience outputs through feeling that they are standing in front of the "real" Earth. However, those systems are too large, complicated, and expensive to be used in classrooms and local science museums. We developed an easy method to display global geoscience data in three dimensions without any complex and expensive systems. The method uses a normal PC projector, a PC and a hemispheric screen. To display the geoscience data, virtual globe software, such as Google Earth and NASA World Wind, are used. The virtual globe software makes geometry conversion. That is, the fringe areas are shrunken as it is looked from the space. Thus, when the image made by the virtual globe is projected on the hemispheric screen, it is reversely converted to its original shape on the Earth. This method does not require any specific software, projectors and polarizing glasses to make 3D presentation of the Earth. Only a hemispheric screen that can be purchased with $50 for 60cm diameter is necessary. Dagik Earth is the project that develops and demonstrates the educational programs of geoscience in classrooms and science museums using this 3D Earth presentation method. We have developed a few programs on aurora and weather system, and demonstrated them in under-graduate level classes and science museums, such as National Museum of Nature and Science,Tokyo, Shizuoka Science Center and Kyoto University Museum, since 2007. Package of hardware, geoscience data plot, and textbook have been developed to be used as short-term rental to schools and science museums. Portability, low cost and easiness of development new contents are advantages of Dagik Earth comparing to the other similar 3D systems.

Effect of planetary rotation on the differentiation of a terrestrial magma ocean in spherical geometry

NASA Astrophysics Data System (ADS)

Hansen, Ulrich; Maas, Christian

2017-04-01

About 4.5 billion years ago the early Earth experienced several giant impacts that lead to one or more deep terrestrial magma oceans of global extent. The crystallization of these vigorously convecting magma oceans is of key importance for the chemical structure of the Earth, the subsequent mantle evolution as well as for the initial conditions for the onset of plate tectonics. Due to the fast planetary rotation of the early Earth and the small magma viscosity, rotation probably had a profound effect on early differentiation processes and could for example influence the presence and distribution of chemical heterogeneities in the Earth's mantle [e.g. Matyska et al., 1994, Garnero and McNamara, 2008]. Previous work in Cartesian geometry revealed a strong influence of rotation as well as of latitude on the crystal settling in a terrestrial magma ocean [Maas and Hansen, 2015]. Based on the preceding study we developed a spherical shell model that allows to study crystal settling in-between pole and equator as well as the migration of crystals between these regions. Further we included centrifugal forces on the crystals, which significantly affect the lateral and radial distribution of the crystals. Depending on the strength of rotation the particles accumulate at mid-latitude or at the equator. At high rotation rates the dynamics of fluid and particles are dominated by jet-like motions in longitudinal direction that have different directions on northern and southern hemisphere. All in all the first numerical experiments in spherical geometry agree with Maas and Hansen [2015] that the crystal distribution crucially depends on latitude, rotational strength and crystal density.

During a later stage of the accretion about 4.5 billion years ago the early Earth experienced several giant impacts that lead to one or more deep terrestrial magma oceans of global extent. The crystallization of these vigorously convecting magma oceans is of key importance for the chemical structure of the Earth, the subsequent mantle evolution as well as for the initial conditions for the onset of plate tectonics. Due to the fast planetary rotation of the early Earth and the small magma viscosity, rotation probably had a profound effect on early differentiation processes of the mantle and could for example influence the presence and distribution of chemical heterogeneities in the Earth mantle [e.g. Matyska et al., 1994, Garnero and McNamara, 2008].Our previous work in Cartesian geometry studied crystal settling in the polar and equatorial regions separately from each other and revealed a strong influence of rotation as well as of latitude on the crystal settling in a terrestrial magma ocean [Maas and Hansen, 2015]. Based on the preceding study we recently developed a spherical shell model that allows for new insights into the crystal settling in-between the pole and the equator as well as the migration of crystals between these regions. Further the spherical model allows us to include the centrifugal force on the crystals, which significantly affects the lateral and radial distribution of crystals. All in all the first numerical experiments in spherical geometry agree with the results of Maas and Hansen [2015] and show that the crystal distribution crucially depends on latitude, rotational strength and crystal density.

COMUNICA Project: a commitment for strategic communication on Earth Sciences

NASA Astrophysics Data System (ADS)

2016-04-01

The Institute of Earth Sciences Jaume Almera (ICTJA-CSIC) has just celebrated its 50-year anniversary last year. It is a reference research center on Earth Sciences both national and international level. The Institute includes 4 research groups which focus their scientific activity on the structure and dynamics of the Earth, the environmental changes in the geological record, geophysical and geochemical modelling and crystallography and optical properties. Only when large geological disasters happens, mainly earthquakes and volcanic eruptions, some interaction between ICTJA-CSIC researchers and traditional media occurs, which is limited by the fact that the aim of the Institute is the scientific research and it has no responsibilities in the area of civil protection. This relationship reduces the knowledge of our activity to the general public. To overcome this situation, the ICTJA-CSIC has decided to take an active role in the social dissemination of geological and geophysical knowledge. Thus, the ICTJA-CSIC has launched the COMUNICA Project. The project is aimed to increase the social visibility of the ICTJA-CSIC and to promote the outreach of researchers. Therefore ICTJA-CSIC has created the Communication Unit, which is in charge of designing communication strategies to give to different audiences (media, students of secondary and higher education, general public) an overview of the scientific and institutional activity of the ICTJA-CSIC. A global communication plan is being designed to define the strategic actions, both internal and external. An important role has been reserved for digital channels, to promote ICTJA-CSIC activity on social networks such as Twitter, Facebook or Youtube, besides making a major effort in the renovation and maintenance of the corporate website. A strong effort will be done to collect and spread through press releases the major scientific milestones achieved by the researchers, to promote the interest of mass media. Communication plan includes also institutional participation in scientific dissemination events, talks addressed to general public, and workshops and seminars for students of secondary and higher education.

The Space Communications and Navigation, Constellation Integration Project (SCIP) is tasked with defining, developing, deploying and operating an evolving multi-decade communications and navigation (C/N) infrastructure including services and subsystems that will support both robotic and human exploration activities at the Moon. This paper discusses an early far side gravitational mapping service and related telecom subsystem that uses an existing spacecraft (WIND) and the Lunar Reconnaissance Orbiter (LRO) to collect data that would address several needs of the SCIP. An important aspect of such an endeavor is to vastly improve the current lunar gravity model while demonstrating the navigation and stationkeeping of a relay spacecraft. We describe a gravity data acquisition activity and the trajectory design of the relay orbit in an Earth-Moon L2 co-linear libration orbit. Several phases of the transfer from an Earth-Sun to the Earth-Moon region are discussed along with transfers within the Earth-Moon system. We describe a proposed, but not integrated, add-on to LRO scheduled to be launched in October of 2008. LRO provided a real host spacecraft against which we designed the science payload and mission activities. From a strategic standpoint, LRO was a very exciting first flight opportunity for gravity science data collection. Gravity Science data collection requires the use of one or more low altitude lunar polar orbiters. Variations in the lunar gravity field will cause measurable variations in the orbit of a low altitude lunar orbiter. The primary means to capture these induced motions is to monitor the Doppler shift of a radio signal to or from the low altitude spacecraft, given that the signal is referenced to a stable frequency reference. For the lunar far side, a secondary orbiting radio signal platform is required. We provide an in-depth look at link margins, trajectory design, and hardware implications. Our approach posed minimum risk to a host mission while maintaining a very low implementation and operations cost.

The TXESS Revolution: A Partnership to Advance Earth and Space Science in Texas

NASA Astrophysics Data System (ADS)

Ellins, K. K.; Olson, H. C.; Willis, M.

2007-12-01

The Texas State Board of Education voted in 2006 to require a fourth year of science for graduation from high school and to authorize the creation of a new senior level Earth Systems and Space Science course as an option to fulfill that requirement. The new Earth Systems and Space Science course will be a capstone course for which three required science courses(biology, chemistry and physics)are prerequisites. Here, we summarize the collective efforts of business leaders, scientists and educators who worked collaboratively for almost a decade to successfully reinstate Earth science as part of Texas' standard high school curriculum and describe a new project, the Texas Earth and Space Science (TXESS) Revolution, a 5-year professional development program for 8th -12th grade minority and minority-serving science teachers and teacher mentors in Texas to help prepare them to teach the new capstone course. At the heart of TXESS Revolution is an extraordinary partnership, involving (1) two UT-Austin academic units, the Jackson School of Geosciences and the Department of Petroleum and Geosystems Engineering; (2) TERC, a not-for-profit educational enterprise in Massachusetts with 30 years experience in designing science curriculum; (3) the University of South Florida; and (4) the Texas Regional Collaboratives for Excellence in Science and Mathematics Teaching, a statewide network of teacher mentors and science teachers. With guidance from the Texas Education Agency, the state agency charged with overseeing education, the TXESS Revolution project will provide teachers with access to high quality materials and instruction aligned with the Texas educational standards for the new capstone course through: a program of eight different 3-day professional development academies offered to both teachers and teachers mentors; immersive summer institutes, field experiences, and a Petroleum Science and Technology Institute; training on how to implement Earth Science by Design, a teacher professional development program developed by TERC and the American Geological Institute with National Science Foundation (NSF) funding; and an online learning forum designed to keep teachers and teacher mentors in contact with facilitators and fellow project-participants between and after training, as well as share best practices and new information. The new capstone course promises to be a rigorous and dynamic change to the way Earth and Space Science has been presented previously anywhere in the U.S. and will provide many opportunities for professional development and the dissemination of suitable Earth and Space Science curriculum. The TXESS Revolution project welcomes opportunities to collaborate with geoscience consortia, programs, organizations and geoscience educators to advance Earth and Space Science in Texas. NSF's Opportunities to Enhance Diversity in the Geosciences program, the Shell Oil Company and the Jackson School of Geosciences are together funding the TXESS Revolution project.

SinoProbe - A Multidisciplinary Research Program of Earth Sciences in China (Invited)

China occupies a large region of central and eastern Asia and holds keys to resolving several first-order problems in Earth Sciences. Besides the importance in Earth Science research, the rapid growth of Chinese economy also demands a comprehensive and systematic evaluation of its natural resources and the impacts of geohazards on its societal development. In order to address the above issues, the Chinese government had initiated a new multidisciplinary research project in Earth Sciences - the SinoProbe Program. Its fundamental goal is to determine the three-dimensional structure, composition distribution, and geological evolution of the Chinese continental lithosphere. The results of the SinoProbe Program are expected to have broad impacts on the Chinese society and economy. In particular, the program will greatly enhance our current understanding on (1) the forming and distribution of mineral resources in the nation, (2) the locations and recurrence histories of major active fault zones capable of generating large earthquakes in highly populated regions, and (3) the distribution of major hazard-prone regions induced by geological processes. In 2009, more than 720 investigators and 70 engineers from Chinese institutions are currently involved with the research program. Sinoprobe hope that the joint forces by Chinese and international researchers will bring in modern approaches, new analytical tools, and advanced exploration technology into the successful operation of the program. In past year, 1,960km long seismic reflection profiling with broadband seismological studies and MT surveys separated from 6 profiles in China continent have completed. MT array coved the North China craton by 1°×1° network and 3-D exploration in larger ore deposits in selected area were carried out. A scientific drilling area operated in Tibet. We started to establish a geochemical reference framework for the values of 76 elements in a grid network with data-point spacing of 160 km in China. Some stress monitoring were centered in the Beijing and the southeastern margin of the Qinghai-Tibet Plateau regions. Also, SinoProbe begin to establish a high-performance calculation platform that will consider coupling processes between deformation and thermal evolution in the lithosphere. Meanwhile, data integration and data dissemination is going to stored. Finally, SinoProbe will also devote to develop new technologies, innovative methods, data integration platforms, and modern equipments for deep Earth and mineral-deposit explorations. In summary, SinoProbe is a multi-year and multidisciplinary research program to be carried in China with 9 projects and 49 sub-projects. It will integrate geological, geophysical, geochemical, and modern exploration technology to examine the deep Earth structures and their evolution in China. The results will undoubtedly contribute to the improvement of our current understanding of the Eurasia continent in particular and the Earth in general.

BOOK REVIEW: Science and Eastern Orthodoxy. From the Greek Fathers to the Age of Globalization.

NASA Astrophysics Data System (ADS)

Nicolaidis, E.; Sterken, C.

2014-01-01

The long debate on the ambivalent relation between science and religion in Western civilization is well documented in the literature on the history and philosophy of science and religion, but few studies paid attention to that relation within Eastern civilization. Nicolaidis' book provides an overview of the relationship between science and Christian Orthodoxy, the official church of the Oriental Roman Empire. The study covers a time span from the fourth to the twentieth century. The author documents the vision that conflicts between science and the Greek Orthodox church were not science versus Christianity, but rather ecclesiastical debates that traversed the whole of society. This book provides a wealth of information concerning the attitude of the Orthodox (i.e., non-Slavic) Church to science today as well as in the past. But the book covers much more than science and religion: also political debates are documented, as well as the role played by Byzantine emperors in relation with science and Orthodoxy. The book presents a very useful time line of events and works covering circa AD 300-1980. There are short descriptions of the Ptolemaic cosmos, the spherical universe with its seven planets (i.e., excluding the Earth, but including Sun and Moon), the Hellenic Aristotelian world view, the duration of the world (eternal or created), the place of the Earth, the matter of creation, the nature of darkness and light, day and night, the Sun and stars, the laws of nature. The last two chapters about Greece, from the independence to the European Union (but also covering science and religion in the Greek State), are quite interesting. Particularly fascinating for astronomers is the fact that the very first establishment (in 1842) of the Greek nation-state that could be termed a research institute was the Observatory of Athens, made possible by a donation from a very wealthy diaspora Greek who resided in Vienna. This is a very useful book to serve as supportive document for the teaching of the history of science and philosophy. It is a well-researched work, with more than 450 notes, and a dozen pages of references. It is a pity, though, that the substantial geographical references and descriptions are not supported by even a single geographical map to guide the reader around Greece and Byzantium. Unfortunately, this publication is pockmarked by just too many typographical errors that were left in place during the copy-editing process. Worse even is the terrible habit of the translator of transposing native first names into modern English look-alikes: John the Grammarian, Marc Eugenicos, John Moisiodax, and the most ridiculous "John Dominique" Cassini (for Giovanni Domenico/Jean-Dominique).

Image Detective 2.0 engages citizen scientists with NASA astronaut photography of the Earth obtained by crew members on the International Space Station (ISS). Engaged citizen scientists are helping to build a more comprehensive and searchable database by geolocating this imagery and contributing to new imagery collections. Image Detective 2.0 is the newest addition to the suite of citizen scientist projects available through CosmoQuest, an effort led by the Astronomical Society of the Pacific (ASP) and supported through a NASA Science Mission Directorate Cooperative Agreement Notice award. CosmoQuest hosts a number of citizen science projects enabling individuals from around the world to engage in authentic NASA science. Image Detective 2.0, an effort that focuses on imagery acquired by astronauts on the International Space Station, builds on work initiated in 2012 by scientists and education specialists at the NASA Johnson Space Center. Through the many lessons learned, Image Detective 2.0 enhances the original project by offering new and improved options for participation. Existing users, as well as new Image Detective participants joining through the CosmoQuest platform, gain first-hand experience working with astronaut photography and become more engaged with this valuable data being obtained from the International Space Station. Citizens around the world are captivated by astronauts living and working in space. As crew members have a unique vantage point from which to view our Earth, the Crew Earth Observations (CEO) online database, referred to as the Gateway to Astronaut Photography of Earth (https://eol.jsc.nasa.gov/), provides a means for crew members to share their unique views of our home planet from the ISS with the scientific community and the public. Astronaut photography supports multiple uses including scientific investigations, visualizations, education, and outreach. These astronaut images record how the planet is changing over time, from human-made changes like urban growth and agriculture, to natural features and landforms such as tropical cyclones, aurora, coastlines, volcanoes and more. This imagery provides researchers on Earth with data to understand the planet from the perspective of the ISS, and is a useful complement to other remotely sensed datasets collected from robotic satellite platforms.

U.S. Government Open Internet Access to Sub-meter Satellite Data

The National Geospatial-Intelligence Agency (NGA) has contracted United States commercial remote sensing companies GeoEye and Digital Globe to provide very high resolution commercial quality satellite imagery to federal/state government agencies and those projects/people who support government interests. Under NextView contract terms, those engaged in official government programs/projects can gain online access to NGA's vast global archive. Additionally, data from vendor's archives of IKONOS-2 (IK-2), OrbView-3 (OB-3), GeoEye-1 (GE-1), QuickBird-1 (QB-1), WorldView-1 (WV-1), and WorldView-2 (WV-2), sensors can also be requested under these agreements. We report here the current extent of this archive, how to gain access, and the applications of these data by Earth science investigators to improve discoverability and community use of these data. Satellite commercial quality imagery (CQI) at very high resolution (< 1 m) (here after referred to as CQI) over the past decade has become an important data source to U.S. federal, state, and local governments for many different purposes. The rapid growth of free global CQI data has been slow to disseminate to NASA Earth Science community and programs such as the Land-Cover Land-Use Change (LCLUC) program which sees potential benefit from unprecedented access. This article evolved from a workshop held on February 23rd, 2012 between representatives from NGA, NASA, and NASA LCLUC Scientists discussion on how to extend this resource to a broader license approved community. Many investigators are unaware of NGA's archive availability or find it difficult to access CQI data from NGA. Results of studies, both quality and breadth, could be improved with CQI data by combining them with other moderate to coarse resolution passive optical Earth observation remote sensing satellites, or with RADAR or LiDAR instruments to better understand Earth system dynamics at the scale of human activities. We provide the evolution of this effort, a guide for qualified user access, and describe current to potential use of these data in earth science.

Diverse organizations are increasingly using project mapping to communicate location-based information about their activities. NASA's Earth Science Division (ESD), through the Earth Science Data Systems and Applied Sciences' Capacity Building Program (CBP), has created a geographic information system of all ESD projects to support internal program management for the agency. The CBP's NASA DEVELOP program has built an interactive mapping tool to support capacity building for the program's varied constituents. This presentation will explore the types of programmatic opportunities provided by a geographic approach to management, communication, and strategic planning. We will also discuss the various external benefits that mapping supports and that build capacity in the Earth sciences. These include activities such as project matching (location-focused synergies), portfolio planning, inter- and intra-organizational collaboration, science diplomacy, and basic impact analysis.

Students at Utah State University's College of Natural Resources have engineered the first mobile Earth Science outreach platform capable of delivering high-tech and interactive solar-powered educational resources to the traditionally-underserved, remote communities of rural Utah. By retrofitting and modifying an industrial box-truck, this project effectively created a highly mobile and energy independent "school in a box" which seeks to help change the way that Earth science is communicated, eliminate traditional barriers, and increase science accessibility - both physically and conceptually. The project's education platform is focused on developing a more effective, sustainable, and engaging platform for presenting Earth science outreach curricula to community members of all ages in an engaging fashion. Furthermore, this project affords university students the opportunity to demonstrate innovative science communication techniques, translating vital university research into educational outreach operations aimed at doing real, measurable good for local communities.

Reforming Earth science education in developing countries

NASA Astrophysics Data System (ADS)

Aswathanarayana, U.

Improving the employability of Earth science graduates by reforming Earth science instruction is a matter of concern to universities worldwide. It should, however, be self-evident that the developing countries cannot follow the same blueprint for change as the industrialized countries due to constraints of affordability and relevance. Peanuts are every bit as nutritious as almonds; if one with limited means has to choose between a fistful of peanuts and just one almond, it is wise to choose the peanuts. A paradigm proposed here would allow institutions in developing countries to impart good quality relevant Earth science instruction that would be affordable and lead to employment.

NASA's Earth Science Data Systems Standards Process Experiences

NASA Technical Reports Server (NTRS)

Ullman, Richard E.; Enloe, Yonsook

2007-01-01

NASA has impaneled several internal working groups to provide recommendations to NASA management on ways to evolve and improve Earth Science Data Systems. One of these working groups is the Standards Process Group (SPC). The SPG is drawn from NASA-funded Earth Science Data Systems stakeholders, and it directs a process of community review and evaluation of proposed NASA standards. The working group's goal is to promote interoperability and interuse of NASA Earth Science data through broader use of standards that have proven implementation and operational benefit to NASA Earth science by facilitating the NASA management endorsement of proposed standards. The SPC now has two years of experience with this approach to identification of standards. We will discuss real examples of the different types of candidate standards that have been proposed to NASA's Standards Process Group such as OPeNDAP's Data Access Protocol, the Hierarchical Data Format, and Open Geospatial Consortium's Web Map Server. Each of the three types of proposals requires a different sort of criteria for understanding the broad concepts of "proven implementation" and "operational benefit" in the context of NASA Earth Science data systems. We will discuss how our Standards Process has evolved with our experiences with the three candidate standards.

Urban fifth graders' connections-making between formal earth science content and their lived experiences

NASA Astrophysics Data System (ADS)

Brkich, Katie Lynn

2014-03-01

Earth science education, as it is traditionally taught, involves presenting concepts such as weathering, erosion, and deposition using relatively well-known examples—the Grand Canyon, beach erosion, and others. However, these examples—which resonate well with middle- and upper-class students—ill-serve students of poverty attending urban schools who may have never traveled farther from home than the corner store. In this paper, I explore the use of a place-based educational framework in teaching earth science concepts to urban fifth graders and explore the connections they make between formal earth science content and their lived experiences using participant-driven photo elicitation techniques. I argue that students are able to gain a sounder understanding of earth science concepts when they are able to make direct observations between the content and their lived experiences and that when such direct observations are impossible they make analogies of appearance, structure, and response to make sense of the content. I discuss additionally the importance of expanding earth science instruction to include man-made materials, as these materials are excluded traditionally from the curriculum yet are most immediately available to urban students for examination.

Overview of the Earth System Science Education Alliance Online Courses

Botti, J. A.

2001-12-01

Science education reform has skyrocketed over the last decade in large part thanks to technology-and one technology in particular, the Internet. The World Wide Web has opened up dynamic new online communities of learners. It has allowed educators from around the world to share thoughts about Earth system science and reexamine the way science is taught. A positive offshoot of this reform effort is the Earth System Science Education Alliance (ESSEA). This partnership among universities, colleges, and science education organizations is led by the Institute for Global Environmental Strategies and the Center for Educational TechnologiesTM at Wheeling Jesuit University. ESSEA's mission is to improve Earth system science education. ESSEA has developed three Earth system science courses for K-12 teachers. These online courses guide teachers into collaborative, student-centered science education experiences. Not only do these courses support teachers' professional development, they also help teachers implement Earth systems science content and age-appropriate pedagogical methods into their classrooms. The ESSEA courses are open to elementary, middle school, and high school teachers. Each course lasts one semester. The courses begin with three weeks of introductory content. Then teachers develop content and pedagogical and technological knowledge in four three-week learning cycles. The elementary school course focuses on basic Earth system interactions between land, life, air, and water. In week A of each learning cycle, teachers do earth system activities with their students. In week B teachers investigate aspects of the Earth system -- for instance, the reason rocks change to soil, the relationship between rock weathering and soil nutrients, and the consequent development of biomes. In week C teachers develop classroom activities and share them online with other course participants. The middle school course stresses the effects of real-world events -- volcanic eruptions, hurricanes, rainforest destruction -- on Earth's lithosphere, atmosphere, biosphere, and hydrosphere. Teachers team during week A of each cycle to research the effect of each event on individual spheres. In week B groups "jigsaw" to study the interactions between events, spheres, and positive and negative feedback loops. In week C teachers develop classroom activities. The high school course uses problem-based learning to examine critical areas of global change, such as coral reef degradation, ozone depletion, and climate change. The ESSEA presentation provides examples of learning environments from each of the three courses.

Value of Earth Observations: NASA Activities with Socioeconomic Analysis

NASA Astrophysics Data System (ADS)

Friedl, L.

2016-12-01

There is greater emphasis internationally on the social and economic benefits that organizations can derive from applications of Earth observations. A growing set of qualitative, anecdotal examples on the uses of Earth observations across a range of sectors can be complemented by the quantitative substantiation of the socioeconomic benefits. In turn, the expanding breadth of environmental data available and the awareness of their beneficial applications to inform decisions can support new products and services. To support these efforts, there are needs to develop impact assessments, populate the literature, and develop familiarity in the Earth science community with the terms, concepts and methods to assess impacts. Within NASA, the Earth Science Division's Applied Sciences Program has initiated and supported numerous activities in recent years to quantify the socioeconomic benefits from Earth observations applications and to build familiarity within the Earth science community. This paper will present an overview of measuring socioeconomic impacts of Earth observations and how the measures can be translated into a value of Earth observation information. It will address key terms, techniques, principles and applications of socioeconomic impact analyses. It will also discuss activities to support analytic techniques, expand the literature, and promote broader skills and capabilities.

We have developed a four-dimensional display system of the Earth and planets to use in schools, science centers, and research institutes. It can display the Earth and planets in three-dimensional way without glasses, and the time variation of the scientific data can be displayed on the Earth and planets image. The system is named Dagik Earth, and educational programs using Dagik Earth have been developed for schools and science centers. Three dimensional displays can show the Earth and planets in exact form without any distortion, which cannot be achieved with two-dimensional display. Furthermore it can provide a sense of reality. There are several systems for the three-dimensional presentation of the Earth, such as Science on a sphere by NOAA, and Geocosmos by Miraikan, Japan. Comparing these systems, the advantage of Dagik Earth is portability and affordability. The system uses ordinary PC and PC projector. Only a spherical screen is the special equipment of Dagik Earth. Therefore Dagik Earth is easy to use in classrooms. Several educational programs have been developed and carried out in high schools, junior high schools, elementary schools and science centers. Several research institutes have used Dagik Earth in their public outreach programs to demonstrate their novel scientific results to public in an attractive way of presentation. A community of users and developers of Dagik Earth is being formed in Japan. In the presentation, the outline of Dagik Earth and the educational programs using Dagik Earth will be presented. Its future plan will also be discussed.

Teaching climate science within the transdisciplinary framework of Critical Zone science

NASA Astrophysics Data System (ADS)

White, T. S.; Wymore, A.; Dere, A. L. D.; Washburne, J. C.; Hoffman, A.; Conklin, M. H.

2017-12-01

During the past decade a new realm of Earth surface and environmental science has evolved, Critical Zone (CZ) science. The CZ is the outermost layer of the continents spanning from the top of the vegetation canopy down to the bottom of the fresh groundwater zone. CZ science integrates across many disciplines and cross cutting concepts, including climate science, and much progress has been made by the CZ community to develop educational curricula - descriptions of the climate science aspects of two of those follows. An interdisciplinary team of CZ scientists developed an undergraduate course entitled "Introduction to CZ science". The semester-long course is modular, has been tested in multiple university settings, and the content is available online. A primary tenet of the course is that to achieve environmental sustainability, society must understand the CZ system, the natural processes and services of the CZ that are of value to society, and how those processes operate with and without the presence of humanity. A fundamental concept in the course is that the fluxes of water, C, energy, reactive gases, particulates and nutrients throughout the CZ are directly and indirectly related to climatic phenomenon and processes. Units on land-atmosphere interactions, weathering, and water budgets highlight the connection between CZ science and climate science, and are augmented by learning activities that consider climate links to soil development and landscape evolution. An online open-source course entitled "Earth 530: Earth Surface Processes in the Critical Zone'" is offered as part of The Pennsylvania State University's Masters of Education in Earth Sciences program. The course is designed to educate teachers interested in incorporating CZ science into their classrooms, though it is usable by anyone with a basic understanding of Earth surface and environmental science. Earth 530 introduces students to knowledge needed to understand the CZ through integration of transdisciplinary science. The course structure is organized into seven units; those covering the atmosphere and climate, water, and landforms, are of particular interest to this session. Earth 530 is unique from the introductory course discussed previously in that students also consider paleoclimate and future climate predictions as part of this curriculum.

Digital Object Identifiers (DOIs) are applied to selected data sets at the NASA Goddard Earth Sciences Data and Information Services Center (GES DISC). The DOI system provides an Internet resolution service for unique and persistent identifiers of digital objects. Products assigned DOIs include data from the NASA MEaSUREs Program, the Earth Observing System (EOS) Aqua Atmospheric Infrared Sounder (AIRS) and EOS Aura High Resolution Dynamics Limb Sounder (HIRDLS). DOIs are acquired and registered through EZID, California Digital Library and DataCite. GES DISC hosts a data set landing page associated with each DOI containing information on and access to the data including a recommended data citation when using the product in research or applications. This work includes participation with the earth science community (e.g., Earth Science Information Partners (ESIP) Federation) and the NASA Earth Science Data and Information System (ESDIS) Project to identify, establish and implement best practices for assigning DOIs and managing supporting information, including metadata, for earth science data sets. Future work includes (1) coordination with NASA mission Science Teams and other data providers on the assignment of DOIs for other GES DISC data holdings, particularly for future missions such as Orbiting Carbon Observatory -2 and -3 (OCO-2, OCO-3) and projects (MEaSUREs 2012), (2) construction of landing pages that are both human and machine readable, and (3) pursuing the linking of data and publications with tools such as the Thomson Reuters Data Citation Index.

Science Goals of the Primary Atomic Reference Clock in Space (PARCS) Experiment

NASA Technical Reports Server (NTRS)

Ashby, N.

2003-01-01

The PARCS (Primary Atomic Reference Clock in Space) experiment will use a laser-cooled Cesium atomic clock operating in the microgravity environment aboard the International Space Station (ISS) to provide both advanced tests of gravitational theory and to demonstrate a new cold-atom clock technology for space. PARCS is a joint project of the National Institute of Standards and Technology (NIST), NASA's Jet Propulsion Laboratory (JPL), and the University of Colorado (CU). This paper concentrates on the scientific goals of the PARCS mission. The microgravity space environment allows laser-cooled Cs atoms to have Ramsey times in excess of those feasible on Earth, resulting in improved clock performance. Clock stabilities of 5x10(exp -14) at one second, and accuracies better than 10(exp -16) are projected.

ESSEA as an Enhancement to K-12 Earth Systems Science Efforts at San José State University

NASA Astrophysics Data System (ADS)

Messina, P.; Metzger, E. P.; Sedlock, R. L.

2002-12-01

San José State University's Geology Department has implemented and maintained a two-fold approach to teacher education efforts. Both pre-service and in-service populations have been participants in a wide variety of content-area enrichment, training, and professional development endeavors. Spearheading these initiatives is the Bay Area Earth Science Institute (BAESI); organized in 1990, this program has served more than 1,000 teachers in weekend- and summer-workshops, and field trips. It sustains a network of Bay Area teachers via its Website (http://www.baesi.org), newsletter, and allows teachers to borrow classroom-pertinent materials through the Earth Science Resource Center. The Department has developed a course offering in Earth Systems Science (Geology 103), which targets pre-service teachers within SJSU's multiple-subject credential program. The curriculum satisfies California subject matter competency requirements in the geosciences, and infuses pedagogy into the syllabus. Course activities are intended for pre-service and in-service teachers' adaptation in their own classrooms. The course has been enhanced by two SJSU-NASA collaborations (Project ALERT and the Sun-Earth Connection Education Forum), which have facilitated incorporation of NASA data, imagery, and curricular materials. SJSU's M.A. in Natural Science, a combined effort of the Departments of Geology, Biology, and Program in Science Education, is designed to meet the multi-disciplinary needs of single-subject credential science teachers by providing a flexible, individually-tailored curriculum that combines science course work with a science education project. Several BAESI teachers have extended their Earth science knowledge and teaching skills through such projects as field guides to local sites of geological interest; lab-based modules for teaching about earthquakes, rocks and minerals, water quality, and weather; and interactive online materials for students and teachers of science. In keeping with SJSU's alliance with NASA Centers, the Geology Department is proud to offer ESSEA online courses as part of its multi-dimensional approach to Earth Systems teacher education. SJSU plans to offer both the middle- and high-school courses to a national audience, beginning spring 2003. The addition of ESSEA courses will complement existing projects, and will help to build a stronger Earth Systems-savvy community.

General Education Engagement in Earth and Planetary Science through an Earth-Mars Analog Curriculum

Chan, M. A.; Kahmann-Robinson, J. A.

2012-12-01

The successes of NASA rovers on Mars and new remote sensing imagery at unprecedented resolution can awaken students to the valuable application of Earth analogs to understand Mars processes and the possibilities of extraterrestrial life. Mars For Earthlings (MFE) modules and curriculum are designed as general science content introducing a pedagogical approach of integrating Earth science principles and Mars imagery. The content can be easily imported into existing or new general education courses. MFE learning modules introduce students to Google Mars and JMARS software packages and encourage Mars imagery analysis to predict habitable environments on Mars drawing on our knowledge of extreme environments on Earth. "Mars Mission" projects help students develop teamwork and presentation skills. Topic-oriented module examples include: Remote Sensing Mars, Olympus Mons and Igneous Rocks, Surface Sculpting Forces, and Extremophiles. The learning modules package imagery, video, lab, and in-class activities for each topic and are available online for faculty to adapt or adopt in courses either individually or collectively. A piloted MFE course attracted a wide range of non-majors to non-degree seeking senior citizens. Measurable outcomes of the piloted MFE curriculum were: heightened enthusiasm for science, awareness of NASA programs, application of Earth science principles, and increased science literacy to help students develop opinions of current issues (e.g., astrobiology or related government-funded research). Earth and Mars analog examples can attract and engage future STEM students as the next generation of earth, planetary, and astrobiology scientists.

Experiences in Bridging the Gap Between Science and Decision Making at NASAs GSFC Earth Sciences Data and Information Services Center (GES DISC)

Kempler, S.; Teng, W.; Friedl, L.; Lynnes, C.

2008-12-01

In recognizing the significance of NASA remote sensing Earth science data in monitoring and better understanding our planet's natural environment, NASA has implemented the 'Decision Support Through Earth Science Research Results' program to solicit "proposals that develop and demonstrate innovative and practicable applications of NASA Earth science observations and research"that focus on improving decision making activities", as stated in the NASA ROSES-2008, A.18 solicitation. This very successful program has yielded several monitoring, surveillance, and decision support systems through collaborations with benefiting organizations in the areas of agriculture, air quality, disaster management, ecosystems, public health, water resources, and aviation weather. The Goddard Space Flight Center (GSFC) Earth Sciences Data and Information Services Center (GES DISC) has participated in this program on two projects (one complete, one ongoing), and has had opportune ad hoc collaborations gaining much experience in the formulation, management, development, and implementation of decision support systems utilizing NASA Earth science data. Coupling this experience with the GES DISC's total understanding and vast experience regarding Earth science missions and resulting data and information, including data structures, data usability and interpretation, data interoperability, and information management systems, the GES DISC is in the unique position to more readily identify challenges that come with bringing science data to decision makers. These challenges consist of those that can be met within typical science data usage frameworks, as well as those challenges that arise when utilizing science data for previously unplanned applications, such as decision support systems. The purpose of this presentation is to share GES DISC decision support system project experiences in regards to system sustainability, required data quality (versus timeliness), data provider understanding how decisions are made, which leads to the data receivers willingness to use new types of information to make decisions, as well as other topics. In addition, defining metrics that 'really' evaluate success will be exemplified.

Creating State-based Alliances to Support Earth and Space Science Education Reform

NASA Astrophysics Data System (ADS)

Geary, E. E.; Manduca, C. A.; Barstow, D.

2002-05-01

Seven years after the publication of the National Science Education Standards and adoption of new state science education standards, Earth and space science remains outside the mainstream K-12 curriculum. Currently, less than ten percent of high school students in the United States of America take an Earth or space science course before graduation. This state of affairs is simply unacceptable. "All of us who live on this planet have the right and the obligation to understand Earth's unique history, its dynamic processes, its abundant resources, and its intriguing mysteries. As citizens of Earth, with the power to modify our climate and ecosystems, we also have a personal and collective responsibility to understand Earth so that we can make wise decisions about its and our future". As one step toward addressing this situation, we support the establishment of state-based alliances to promote Earth and space science education reform. "In many ways, states are the most vital locus of change in our nation's schools. State departments of education define curriculum frameworks, establish testing policies, support professional development and, in some cases, approve textbooks and materials for adoption". State alliance partners should include a broad spectrum of K-16 educators, scientists, policy makers, parents, and community leaders from academic institutions, businesses, museums, technology centers, and not-for profit organizations. The focus of these alliances should be on systemic and sustainable reform of K-16 Earth and space science education. Each state-based alliance should focus on specific educational needs within their state, but work together to share ideas, resources, and models for success. As we build these alliances we need to take a truly collaborative approach working with the other sciences, geography, and mathematics so that collectively we can improve the caliber and scope of science and mathematics education for all students.

NASA's Earth Observing Data and Information System - Supporting Interoperability through a Scalable Architecture (Invited)

NASA Astrophysics Data System (ADS)

Mitchell, A. E.; Lowe, D. R.; Murphy, K. J.; Ramapriyan, H. K.

2011-12-01

Initiated in 1990, NASA's Earth Observing System Data and Information System (EOSDIS) is currently a petabyte-scale archive of data designed to receive, process, distribute and archive several terabytes of science data per day from NASA's Earth science missions. Comprised of 12 discipline specific data centers collocated with centers of science discipline expertise, EOSDIS manages over 6800 data products from many science disciplines and sources. NASA supports global climate change research by providing scalable open application layers to the EOSDIS distributed information framework. This allows many other value-added services to access NASA's vast Earth Science Collection and allows EOSDIS to interoperate with data archives from other domestic and international organizations. EOSDIS is committed to NASA's Data Policy of full and open sharing of Earth science data. As metadata is used in all aspects of NASA's Earth science data lifecycle, EOSDIS provides a spatial and temporal metadata registry and order broker called the EOS Clearing House (ECHO) that allows efficient search and access of cross domain data and services through the Reverb Client and Application Programmer Interfaces (APIs). Another core metadata component of EOSDIS is NASA's Global Change Master Directory (GCMD) which represents more than 25,000 Earth science data set and service descriptions from all over the world, covering subject areas within the Earth and environmental sciences. With inputs from the ECHO, GCMD and Soil Moisture Active Passive (SMAP) mission metadata models, EOSDIS is developing a NASA ISO 19115 Best Practices Convention. Adoption of an international metadata standard enables a far greater level of interoperability among national and international data products. NASA recently concluded a 'Metadata Harmony Study' of EOSDIS metadata capabilities/processes of ECHO and NASA's Global Change Master Directory (GCMD), to evaluate opportunities for improved data access and use, reduce efforts by data providers and improve metadata integrity. The result was a recommendation for EOSDIS to develop a 'Common Metadata Repository (CMR)' to manage the evolution of NASA Earth Science metadata in a unified and consistent way by providing a central storage and access capability that streamlines current workflows while increasing overall data quality and anticipating future capabilities. For applications users interested in monitoring and analyzing a wide variety of natural and man-made phenomena, EOSDIS provides access to near real-time products from the MODIS, OMI, AIRS, and MLS instruments in less than 3 hours from observation. To enable interactive exploration of NASA's Earth imagery, EOSDIS is developing a set of standard services to deliver global, full-resolution satellite imagery in a highly responsive manner. EOSDIS is also playing a lead role in the development of the CEOS WGISS Integrated Catalog (CWIC), which provides search and access to holdings of participating international data providers. EOSDIS provides a platform to expose and share information on NASA Earth science tools and data via Earthdata.nasa.gov while offering a coherent and interoperable system for the NASA Earth Science Data System (ESDS) Program.

For applications users interested in monitoring and analyzing a wide variety of natural and man-made phenomena, EOSDIS provides access to near real-time products from the MODIS, OMI, AIRS, and MLS instruments in less than 3 hours from observation. To enable interactive exploration of NASA's Earth imagery, EOSDIS is developing a set of standard services to deliver global, full-resolution satellite imagery in a highly responsive manner. EOSDIS is also playing a lead role in the development of the CEOS WGISS Integrated Catalog (CWIC), which provides search and access to holdings of participating international data providers. EOSDIS provides a platform to expose and share information on NASA Earth science tools and data via Earthdata.nasa.gov while offering a coherent and interoperable system for the NASA Earth Science Data System (ESDS) Program.

Bagwell, R.; Siarto, J.; Wong, M. M.; Murphy, K. J.; McLaughlin, B. D.

2014-12-01

Two years ago, NASA's Earth Science Data and Information Systems (ESDIS) Project launched the Earthdata website (https://earthdata.nasa.gov) in order to make Earth Observing System Data and Information System (EOSDIS) data, data products, data tools, and services available to a broad range of user communities across Earth science disciplines to foster collaboration and learning amongst the communities. Earthdata is being redesigned to be the one-stop shop in providing Earth science data, services, and information to the Earth science community. The goal is to move from the current static, manually-intensive content format to a dynamic, data-driven website in order to provide a more flexible and usable design website infrastructure that leverages EOSDIS components such as the User Registration System (URS), the Common Metadata Repository (CMR) and the Global Imagery Browse Services (GIBS). This will reorganize information content to make the website easier to use and to make easily accessible the high-value Earth science content throughout the site. The website will also easily accept and incorporate upcoming new projects such as the Earthdata Search Client and the Sea Level Change Portal.

JPSS-1 Data and the EOSDIS System: It's seamless

The continuity of climate and environmental data is the key to the NASA Earth science program to develop a scientific understanding of Earth's system and its response to changes. NASA has made a long-term investment in processing, archiving and distributing Earth science data through the Earth Observing System (EOS) Data and Information System (EOSDIS). The use of the EOSDIS infrastructure and services provides seamless integration of Suomi National Polar-Orbiting Partnership (SNPP) and future Joint Polar Satellite System (JPSS-1) products as it does for the entire NASA Earth Science data collection. This continuity of measurements from all the missions is supported by the use of common data structures and standards in the generation of products and the subsequent services, tools and access to those products. Similar to EOS missions, 5 Science Investigator-led Processing Systems (SIPS) were established for SNPP: Land, Ocean, Atmosphere, Ozone, and Sounder along with NASA's Clouds and the Earth's Radiant Energy System and Ozone Mapper/Profiler Suite Limb systems now produce the NASA SNPP standard Level 1, Level 2, and Level 3 products developed by the NASA science teams.

The study investigates NASA's Earth Science Enterprise needs for Distributed Spacecraft Technologies in the 2010-2025 timeframe. In particular, the study focused on the Earth Science Vision Initiative and extrapolation of the measurement architecture from the 2002-2010 time period. Earth Science Enterprise documents were reviewed. Interviews were conducted with a number of Earth scientists and technologists. fundamental principles of formation flying were also explored. The results led to the development of four notional distribution spacecraft architectures. These four notional architectures (global constellations, virtual platforms, precision formation flying, and sensorwebs) are presented. They broadly and generically cover the distributed spacecraft architectures needed by Earth Science in the post-2010 era. These notional architectures are used to identify technology needs and drivers. Technology needs are subsequently grouped into five categories: Systems and architecture development tools; Miniaturization, production, manufacture, test and calibration; Data networks and information management; Orbit control, planning and operations; and Launch and deployment. The current state of the art and expected developments are explored. High-value technology areas are identified for possible future funding emphasis.

Exemplary Programs Supporting Teacher Professional Development in the U.S.A.

NASA Astrophysics Data System (ADS)

Passow, Michael J.

2015-04-01

By Law, there is no national curriculum in the U.S.A., so each State sets its own regulations for teacher certification and professional development. The Next Generation Science Standards (NGSS, http://www.nextgenscience.org/next-generation-science-standards) provide guidelines for teacher training and curriculum development in Earth Science, Life Science, and the physical sciences (chemistry and biology). Presented here are examples of effective programs designed to support in-service Earth Science teachers, especially at the middle school and high school level (grades 6 - 12, ages 12 - 18). The Earth2Class Workshops for Teachers at the Lamont-Doherty Earth Observatory of Columbia University (E2C) provides monthly gatherings of research scientists and teachers to learn about cutting-edge investigations in a wide variety of fields, and develop lesson plans to share these discoveries. The E2C website, www.earth2class.org/site, also provides a wide variety of educational resources used by teachers and students to learn about the planet. The National Earth Science Teachers Association (www.nestanet.org) is the largest professional society focused on pre-college Earth Science education. Together with its partner, Windows to the Universe (www.windows2universe.org), NESTA offers workshops and other programs at national and regional teacher conferences, a quarterly journal designed for classroom use, monthly E-Newsletters, and one of the largest collection of web resources in education. For more than twenty years, the American Meteorological Society has trained teachers across the country through its online courses: DataStreme Weather, DataStreme Ocean, and DataStreme Earth's Climate System (www.ametsoc.org/amsedu). Informal science education institutions also provide strong in-person and web-based professional development programs. Among these are the American Museum of Natural History's "Seminars on Science" (http://www.amnh.org/learn/) and many programs for educators that utilize the AMNH collections in New York City. Each year at the American Geophysical Union Meeting, teachers find out about "Hot Topics in Science" through the GIFT Workshops (http://education.agu.org/education-activities-at-agu-meetings/gift/). Field experiences aboard the scientific ocean drilling vessel, "JOIDES Resolution," have enhanced the knowledge and skills of teachers from the USA and Europe (http://joidesresolution.org/node/3002). Many teachers also connect with each other through the ESPRIT list-serv and others (http://external.oneonta.edu/mentor/listserv.html). These are just a sample of the many programs offered to provide life-long professional development for Earth Science educators and promote 'Science in Tomorrow's Classroom.'

Future Earth, Global Science and Regional Programs: Building regional integrated science capacities in a global science organization

Tewksbury, J.

2016-12-01

Future Earth has emerged from the more than 30-year history of Global Change Research Programs, including IGBP, DIVERSITAS and IHDP. These programs supported interdisciplinary science in service of societies around the world. Now, their focus on building a greater understanding of changing Earth systems and their couplings with society has passed to Future Earth - with an important addition: Future Earth was also established to focus global change efforts around key societal challenges. The implications for the structure of Future Earth are large. Many challenges within topics, such as the water, energy, food nexus or the future of cities, are manifested within local, national, and regional contexts. How should we organize globally to most effectively confront these multi-scale challenges? The solution proposed in the framing of Future Earth was the formation of regional as well as national committees, as well as the formation of regional centers and offices. Regional Committees serve to both advocate for Future Earth in their regions and to advocate for regional interests in the global Future Earth platform, while regional Centers and offices are built into the Future Earth secretariat to perform a parallel regional implementation function. Implementation has not been easy, and the process has placed regionally-focused projects in an awkward place. Programs such as the Monsoon Asia Integrated Regional Study (MAIRS), the Northern Eurasia Earth Science Partnership Initiative (NEESPI), and the South/Southeast Asia Research Initiative (SARI) represent some of the best global change communities in the world, but by design, their focus is regional. The effective integration of these communities into the Future Earth architecture will be critical, and this integration will require the formation of strong regional committees and regional centers.

Preparing Earth Data Scientists for 'the sexiest job of the 21st century'

2014-12-01

What Exactly do Earth Data Scientists do, and What do They Need to Know, to do It? There is not one simple answer, but there are many complex answers. Data Science, and data analytics, are new and nebulas, and takes on different characteristics depending on: The subject matter being analyzed, the maturity of the research, and whether the employed subject specific analytics is descriptive, diagnostic, discoveritive, predictive, or prescriptive, in nature. In addition, in a, thus far, business driven paradigm shift, university curriculums teaching data analytics pertaining to Earth science have, as a whole, lagged behind, and/or have varied in approach. This presentation attempts to breakdown and identify the many activities that Earth Data Scientists, as a profession, encounter, as well as provide case studies of specific Earth Data Scientist and data analytics efforts. I will also address the educational preparation, that best equips future Earth Data Scientists, needed to further Earth science heterogeneous data research and applications analysis. The goal of this presentation is to describe the actual need for Earth Data Scientists and the practical skills to perform Earth science data analytics, thus hoping to initiate discussion addressing a baseline set of needed expertise for educating future Earth Data Scientists.

Evolving Metadata in NASA Earth Science Data Systems

NASA Astrophysics Data System (ADS)

Mitchell, A.; Cechini, M. F.; Walter, J.

2011-12-01

NASA's Earth Observing System (EOS) is a coordinated series of satellites for long term global observations. NASA's Earth Observing System Data and Information System (EOSDIS) is a petabyte-scale archive of environmental data that supports global climate change research by providing end-to-end services from EOS instrument data collection to science data processing to full access to EOS and other earth science data. On a daily basis, the EOSDIS ingests, processes, archives and distributes over 3 terabytes of data from NASA's Earth Science missions representing over 3500 data products ranging from various types of science disciplines. EOSDIS is currently comprised of 12 discipline specific data centers that are collocated with centers of science discipline expertise. Metadata is used in all aspects of NASA's Earth Science data lifecycle from the initial measurement gathering to the accessing of data products. Missions use metadata in their science data products when describing information such as the instrument/sensor, operational plan, and geographically region. Acting as the curator of the data products, data centers employ metadata for preservation, access and manipulation of data. EOSDIS provides a centralized metadata repository called the Earth Observing System (EOS) ClearingHouse (ECHO) for data discovery and access via a service-oriented-architecture (SOA) between data centers and science data users. ECHO receives inventory metadata from data centers who generate metadata files that complies with the ECHO Metadata Model. NASA's Earth Science Data and Information System (ESDIS) Project established a Tiger Team to study and make recommendations regarding the adoption of the international metadata standard ISO 19115 in EOSDIS. The result was a technical report recommending an evolution of NASA data systems towards a consistent application of ISO 19115 and related standards including the creation of a NASA-specific convention for core ISO 19115 elements. Part of NASA's effort to continually evolve its data systems led ECHO to enhancing the method in which it receives inventory metadata from the data centers to allow for multiple metadata formats including ISO 19115. ECHO's metadata model will also be mapped to the NASA-specific convention for ingesting science metadata into the ECHO system. As NASA's new Earth Science missions and data centers are migrating to the ISO 19115 standards, EOSDIS is developing metadata management resources to assist in the reading, writing and parsing ISO 19115 compliant metadata. To foster interoperability with other agencies and international partners, NASA is working to ensure that a common ISO 19115 convention is developed, enhancing data sharing capabilities and other data analysis initiatives. NASA is also investigating the use of ISO 19115 standards to encode data quality, lineage and provenance with stored values. A common metadata standard across NASA's Earth Science data systems promotes interoperability, enhances data utilization and removes levels of uncertainty found in data products.

Array Databases: Agile Analytics (not just) for the Earth Sciences

NASA Astrophysics Data System (ADS)

Baumann, P.; Misev, D.

2015-12-01

Gridded data, such as images, image timeseries, and climate datacubes, today are managed separately from the metadata, and with different, restricted retrieval capabilities. While databases are good at metadata modelled in tables, XML hierarchies, or RDF graphs, they traditionally do not support multi-dimensional arrays.This gap is being closed by Array Databases, pioneered by the scalable rasdaman ("raster data manager") array engine. Its declarative query language, rasql, extends SQL with array operators which are optimized and parallelized on server side. Installations can easily be mashed up securely, thereby enabling large-scale location-transparent query processing in federations. Domain experts value the integration with their commonly used tools leading to a quick learning curve.Earth, Space, and Life sciences, but also Social sciences as well as business have massive amounts of data and complex analysis challenges that are answered by rasdaman. As of today, rasdaman is mature and in operational use on hundreds of Terabytes of timeseries datacubes, with transparent query distribution across more than 1,000 nodes. Additionally, its concepts have shaped international Big Data standards in the field, including the forthcoming array extension to ISO SQL, many of which are supported by both open-source and commercial systems meantime. In the geo field, rasdaman is reference implementation for the Open Geospatial Consortium (OGC) Big Data standard, WCS, now also under adoption by ISO. Further, rasdaman is in the final stage of OSGeo incubation.In this contribution we present array queries a la rasdaman, describe the architecture and novel optimization and parallelization techniques introduced in 2015, and put this in context of the intercontinental EarthServer initiative which utilizes rasdaman for enabling agile analytics on Petascale datacubes.

Lunar Team Report from a Planetary Design Workshop at ESTEC

NASA Astrophysics Data System (ADS)

Gray, A.; MacArthur, J.; Foing, B. H.

2014-04-01

On February 13, 2014, GeoVUsie, a student association for Earth science majors at Vrijie University (VU), Amsterdam, hosted a Planetary Sciences: Moon, Mars and More symposium. The symposium included a learning exercise the following day for a planetary design workshop at the European Space Research and Technology Centre (ESTEC) for 30 motivated students, the majority being from GeoVUsie with little previous experience of planetary science. Students were split into five teams and assigned pre-selected new science mission projects. A few scientific papers were given to use as reference just days before the workshop. Three hours were allocated to create a mission concept before presenting results to the other students and science advisors. The educational backgrounds varied from second year undergraduate students to masters' students from mostly local universities.The lunar team was told to design a mission to the lunar south pole, as this is a key destination agreed upon by the international lunar scientific community. This region has the potential to address many significant objectives for planetary science, as the South Pole-Aitken basin has preserved early solar system history and would help to understand impact events throughout the solar system as well as the origin and evolution of the Earth-Moon system, particularly if samples could be returned. This report shows the lunar team's mission concept and reasons for studying the origin of volatiles on the Moon as the primary science objective [1]. Amundsen crater was selected as the optimal landing site near the lunar south pole [2]. Other mission concepts such as RESOLVE [3], L-VRAP [4], ESA's lunar lander studies and Luna-27 were reviewed. A rover and drill were selected as being the most suitable architecture for the requirements of this mission. Recommendations for future student planetary design exercises were to continue events like this, ideally with more time, and also to invite a more diverse range of educational backgrounds, i.e., both engineering and science students/professionals.

Earth Science Outreach: A Move in the Right Direction

NASA Astrophysics Data System (ADS)

McLarty Halfkenny, B.; Schröder Adams, C.

2009-05-01

There is concern within the Geoscience Community about the public's limited understanding of Earth Science and its fundamental contribution to society. Earth Science plays only a minor role in public school education in Ontario leaving many students to stumble upon this field of study in post-secondary institutions. As the Earth Sciences offer relevant advice for political decisions and provide excellent career opportunities, outreach is an increasingly important component of our work. Recruitment of post-secondary students after they have chosen their discipline cannot remain the sole opportunity. Outreach must be directed to potential students at an early stage of their education. High school teachers are influential, directing students towards professional careers. Therefore we are first committed to reach these teachers. We provide professional development, resources and continued support, building an enthusiastic community of educators. Specific initiatives include: a three day workshop supported by a grant from EdGEO introducing earth science exercises and local field destinations; a resource kit with minerals, rocks, fossils, mineral identification tools and manuals; a CD with prepared classroom exercises; and in-class demonstrations and field trip guiding on request. Maintaining a growing network with teachers has proven highly effective. Direct public school student engagement is also given priority. We inspire students through interaction with researchers and graduate students, hand-on exercises, and by providing opportunities to visit our department and work with our collections. Successful projects include our week-long course "School of Rock" for the Enrichment Mini-Course Program, classroom visits and presentations on the exciting and rewarding career paths in geology during Carleton University open houses. Outreach to the general public allows us to educate the wider community about the Geoheritage of our region, and initiate discussions about science and global issues such as climate science and stewardship of our natural resources. A new initiative for Science and Technology Week, 'Explore Geoheritage Day' introduced the public to the geological history of the National Capital Region. We have found collaborations with other agencies very effective. We work with PDAC's "Mining Matters", LTS, the Ottawa Gatineau Geoheritage Project, Ottawa Heritage, STAO, local school boards, naturalist groups, and other community organizations to promote Earth Science education. Our efforts over the last 5 years have brought tangible results in: a) a considerable increase in student enrolment at the university level in our department; b) increased teaching of the Grade 12 Earth and Space Sciences course at local high schools through teachers who were inspired by our workshops; c) a flourishing network of enthusiastic earth science educators sharing ideas with us to define each other's needs; and d) a growing interaction with the general public. Future initiatives need to consider lobbying for curriculum changes to give Earth Science a prominent place in the public education system. As well, only few university education departments currently allow Earth Science graduates into their programs, requiring them to first take additional courses in other "teachable" subjects. This must change. University graduates with an Earth Science degree and an interest in teaching must be permitted direct entry into these programs so that their skills will be passed on to the next generation of science students.

2015-12-01

Heliophysics is a developing scientific discipline integrating studies of the Sun's variability, the surrounding heliosphere, and climate environments. Over the past few centuries our understanding of how the Sun drives space weather and climate on the Earth and other planets has advanced at an ever-increasing rate. NASA Living With a Star and the UCAR Visiting Scientist Progams sponsor the annual Heliophysics Summer Schools to build the next generation of scientists in this emerging field. The highly successful series of the summer schools (commencing 2007) trains a select group of graduate students, postdoctoral fellows and university faculty to learn and develop the science of heliophysics as a broad, coherent discipline that reaches in space from the Earth's troposphere to the depths of the Sun, and in time from the formation of the solar system to the distant future. Now in its tenth year, the School has resulted in the publication of five Heliophysics textbooks now being used at universities worldwide. The books provide a foundational reference for researchers in space physics, solar physics, aeronomy, space weather, planetary science and climate science, astrophysics, plasma physics,. In parallel, the School also developed the complementary materials that support teaching of heliophysics at both graduate and undergraduate levels. The Jack Eddy Postdoctoral Fellowship Program matches newly graduated postdoctorates with hosting mentors for the purpose of training the next generation researchers needed in heliophysics. The fellowships are for two years, and any U.S. university or research lab may apply to host a fellow. Two major topics of focus for the program are the science of space weather and of the Sun-climate connection. Since the goal of this fellowship program is to train Sun-Earth system researchers, preference is also given to research projects that cross the traditional heliophysics subdomains of the Sun, heliosphere, magnetosphere, and ionosphere/upper atmosphere, as well as Sun-climate investigations. Host mentors plan critical roles. Potential hosts may enter information about their research on a central database.

Bridging the Technology Readiness "Valley of Death" Utilizing Nanosats

NASA Technical Reports Server (NTRS)

Bauer, Robert A.; Millar, Pamela S.; Norton, Charles D.

2015-01-01

Incorporating new technology is a hallmark of space missions. Missions demand ever-improving tools and techniques to allow them to meet the mission science requirements. In Earth Science, these technologies are normally expressed in new instrument capabilities that can enable new measurement concepts, extended capabilities of existing measurement techniques, or totally new detection capabilities, and also, information systems technologies that can enhance data analysis or enable new data analyses to advance modeling and prediction capabilities. Incorporating new technologies has never been easy. There is a large development step beyond demonstration in a laboratory or on an airborne platform to the eventual space environment that is sometimes referred to as the "technology valley of death." Studies have shown that non-validated technology is a primary cause of NASA and DoD mission delays and cost overruns. With the demise of the New Millennium Program within NASA, opportunities for demonstrating technologies in space have been rare. Many technologies are suitable for a flight project after only ground testing. However, some require validation in a relevant or a space flight environment, which cannot be fully tested on the ground or in airborne systems. NASA's Earth Science Technology Program has initiated a nimble program to provide a fairly rapid turn-around of space validated technologies, and thereby reducing future mission risk in incorporating new technologies. The program, called In-Space Validation of Earth Science Technology (InVEST), now has five tasks in development. Each are 3U CubeSats and they are targeted for launch opportunities in the 2016 time period. Prior to formalizing an InVEST program, the technology program office was asked to demonstrate how the program would work and what sort of technologies could benefit from space validation. Three projects were developed and launched, and have demonstrated the technologies that they set out to validate. This paper will provide a brief status of the pre-InVEST CubeSats, and discuss the development and status of the InVEST program. Figure
