Ocean images in music compositions and folksongs

NASA Astrophysics Data System (ADS)

Liu, C. M.

2017-12-01

In general, ocean study usually ranges from physical oceanography, chemical oceanography, marine biology, marine geology, and other related fields. In addition to pure scientific fields, ocean phenomenon influence not only human mood but also the shaping of local cultures. In this paper, we present some ocean images and concepts appeared in music compositions and folksongs to show the mixing, influence and interaction between them. This may give a novel way not for science teachers but also music teachers to deliver the knowledge of ocean science in classes.

Gedzelman, Stanley David

William L. Donn, Professor Emeritus of the Department of Earth and Planetary Sciences, City College of New York, and Special Research Scientist at Lamont-Doherty Geological Observatory (LDGO) of Columbia University (Palisades, N.Y.), died at his home on June 30, 1987, at the age of 69. Bill demonstrated expertise in a wide range of fields, with a highly productive and creative research and writing career that included geology, oceanography, climatology, atmospheric physics, and meteorology.Donn was born in Brooklyn, N.Y., on March 2, 1918. At the tender age of 10 years, he demonstrated his love and talent for science by building a telescope with his brother, Bertram. During his undergraduate years at Brooklyn College, he switched his major from astronomy to geology. He was largely selftrained in both meteorology and oceanography, serving as head of the Meteorology Section, U.S. Merchant Marine Academy during World War II . One by-product of these years was the textbook Meteorology—With Marine Applications, first published in 1946. This widely adopted text became a standard for a generation of mariners and college students.

Putting the Deep Biosphere on the Map for Oceanography Courses: Gas Hydrates As a Case Study for the Deep Biosphere

NASA Astrophysics Data System (ADS)

Sikorski, J. J.; Briggs, B. R.

2014-12-01

The ocean is essential for life on our planet. It covers 71% of the Earth's surface, is the source of the water we drink, the air we breathe, and the food we eat. Yet, the exponential growth in human population is putting the ocean and thus life on our planet at risk. However, based on student evaluations from our introductory oceanography course it is clear that our students have deficiencies in ocean literacy that impact their ability to recognize that the ocean and humans are inextricably connected. Furthermore, life present in deep subsurface marine environments is also interconnected to the study of the ocean, yet the deep biosphere is not typically covered in undergraduate oceanography courses. In an effort to improve student ocean literacy we developed an instructional module on the deep biosphere focused on gas hydrate deposits. Specifically, our module utilizes Google Earth and cutting edge research about microbial life in the ocean to support three inquiry-based activities that each explore different facets of gas hydrates (i.e. environmental controls, biologic controls, and societal implications). The relevant nature of the proposed module also makes it possible for instructors of introductory geology courses to modify module components to discuss related topics, such as climate, energy, and geologic hazards. This work, which will be available online as a free download, is a solid contribution toward increasing the available teaching resources focused on the deep biosphere for geoscience educators.

The status of coastal oceanography in heavily impacted Yellow and East China Sea: Past trends, progress, and possible futures

NASA Astrophysics Data System (ADS)

Wang, Xiao Hua; Cho, Yang-Ki; Guo, Xinyu; Wu, Chau-Ron; Zhou, Junliang

2015-09-01

Coastal environments are a key location for transport, commercial, residential and defence infrastructure, and have provided conditions suitable for economic growth. They also fulfil important cultural, recreational and aesthetic needs; have intrinsic ecosystem service values; and provide essential biogeochemical functions such as primary productivity, nutrient cycling and water filtration. The rapid expansion in economic development and anticipated growth of the population in the coastal zones along the Yellow and East China Sea basin has placed this region under intense multiple stresses. Here we aim to: 1) synthesize the new knowledge/science in coastal oceanography since 2010 within the context of the scientific literature published in English; 2) report on a citation analysis that assesses whether new research topics have emerged and integrated over time, indicate the location of modelling and field-based studies; and 3) suggest where the new research should develop for heavily impacted estuaries and coastal seas of East Asia. The conclusions of the synthesis include: 1) China has emerged as a dominant force in the region in producing scientific literature in coastal oceanography, although the area of publications has shifted from its traditional fields such as physical oceanography; 2) there has been an increasing number of publications with cross-disciplinary themes between physical oceanography and other fields of the biological, chemical, and geological disciplines, but vigorous and systematic funding mechanisms are still lacking to ensure the viability of large scale multi-disciplinary teams and projects in order to support trans-disciplinary research and newly emerging fields; 3) coastal oceanography is responding to new challenges, with many papers studying the impacts of human activities on marine environment and ecology, but so far very few studying management and conservation strategies or offering policy solutions.

Graduate Education in Coastal Science: Then and Now

NASA Astrophysics Data System (ADS)

Inman, D. L.

2002-12-01

Coastal science began in the early 20th century in geology disciplines with descriptive field studies of ancient shorelines (G. K. Gilbert, 1885) and coastal observations (Douglas Johnson, 1919). World War II placed a strong emphasis on the importance of coastal processes in military operations. The most profound impact was associated with the interdisciplinary approach to coastal science demonstrated by The Oceans (1942). The first organized graduate program in oceanography opened at Scripps Institution of Oceanography in 1946 and offered courses in marine geology as well as physical oceanography, biology at the sea, chemistry of sea water and applied mathematics. Those first classes and the new "Sverdrup" curriculum inspired the rapid growth and transfer of knowledge in the new oceanographic sciences. Graduates of these classes established Sverdrup-type interdisciplinary curricula throughout the world. Research and descriptive understanding of the world's oceans and coasts burgeoned during the 1950s. The aqualung, introduced to Shepard's students in 1948 by Jacques Cousteau, became a new scientific tool for studies in nearshore waters, and instruments were designed for studying waves, currents, and sediment transport. A new quantitative coastal science emerged from the concepts of Bagnold and others. Funding came from the Office of Naval Research, coastal engineering (Beach Erosion Board), and the oil industry. A significant contribution to the literature of classical nearshore processes was the series of Conferences on Coastal Engineering sponsored by the University of California and edited by Joe Johnson. Starting with the first conference held in Long Beach in 1950, the conferences brought together researchers from diverse backgrounds and published their findings expeditiously. This research soon was synthesized into textbooks such as Shepard's Submarine Geology (2nd edition, 1963); Hill's 1963 edited volume The Sea v. 3 The Earth Beneath the Sea, with the first discussion of "Beach and Nearshore Processes"; Wiegel's Oceanographical Engineering in 1964; and Ippen's Estuary and Coastline Hydrodynamics in 1966. An excellent example of the transition from descriptive to quantitative nearshore processes is given by comparison between the first edition in 1948 and the second edition in 1963 of Submarine Geology, with sections added on the mechanics of waves, currents, and sediment transport. In the last two decades, the global scale of environmental research and the power of computers have shifted the focus of coastal research to large scale experiments and process modeling.

Every 3 years the U.S. National Science Foundation (NSF), through its Advisory Committee on Geosciences, forms a Committee of Visitors (COV) to review different aspects of the Directorate for Geosciences (GEO). This year a COV was formed to review the Biological Oceanography (BO), Chemical Oceanography (CO), and Physical Oceanography (PO) programs in the Ocean Section; the Marine Geology and Geophysics (MGG) and Integrated Ocean Drilling Program (IODP) science programs in the Marine Geosciences Section; and the Ocean Education and Ocean Technology and Interdisciplinary Coordination (OTIC) programs in the Integrative Programs Section of the Ocean Sciences Division (OCE). The 2012 COV assessed the proposal review process for fiscal year (FY) 2009-2011, when 3843 proposal actions were considered, resulting in 1141 awards. To do this, COV evaluated the documents associated with 206 projects that were randomly selected from the following categories: low-rated proposals that were funded, high-rated proposals that were funded, low-rated proposals that were declined, high-rated proposals that were declined, some in the middle (53 awarded, 106 declined), and all (47) proposals submitted to the Rapid Response Research (RAPID) funding mechanism. NSF provided additional data as requested by the COV in the form of graphs and tables. The full COV report, including graphs and tables, is available at http://www.nsf.gov/geo/acgeo_cov.jsp.

Improving quantitative skills in introductory geoscience courses at a four-year public institution using online math modules

NASA Astrophysics Data System (ADS)

Gordon, E. S.

2011-12-01

Fitchburg State University has a diverse student population comprised largely of students traditionally underrepresented in higher education, including first-generation, low-income, and/or students with disabilities. Approximately half of our incoming students require developmental math coursework, but often enroll in science classes prior to completing those courses. Since our introductory geoscience courses (Oceanography, Meteorology, Geology, Earth Systems Science) do not have prerequisites, many students who take them lack basic math skills, but are taking these courses alongside science majors. In order to provide supplemental math instruction without sacrificing time for content, "The Math You Need, When You Need It (TMYN), a set of online math tutorials placed in a geoscience context, will be implemented in three of our introductory courses (Oceanography, Meteorology, and Earth Systems Science) during Fall, 2011. Students will complete 5-6 modules asynchronously, the topics of which include graphing skills, calculating rates, unit conversions, and rearranging equations. Assessment of quantitative skills will be tracked with students' pre- and post-test results, as well as individual module quiz scores. In addition, student assessment results from Oceanography will be compared to student data from Academic Year 2010-11, during which quantitative skills were evaluated with pre- and post-test questions, but students did not receive online supplemental instruction.

The application of geography markup language (GML) to the geological sciences

NASA Astrophysics Data System (ADS)

Lake, Ron

2005-11-01

GML 3.0 became an adopted specification of the Open Geospatial Consortium (OGC) in January 2003, and is rapidly emerging as the world standard for the encoding, transport and storage of all forms of geographic information. This paper looks at the application of GML to one of the more challenging areas of automated geography, namely the geological sciences. Specific features of GML of interest to geologists are discussed and then illustrated through a series of geological case studies. We conclude the paper with a discussion of anticipated geological web services that GML will enable. GML is written in XML and makes use of XML Schema for extensibility. It can be used both to represent or model geographic objects and to transport them across the Internet. In this way it serves as the foundation for all manner of geographic web services. Unlike vertical application grammars such as LandXML, GML was intended to define geographic application languages, and hence is applicable to any geographic domain including forestry, environmental sciences, geology and oceanography. This paper provides a review of the basic features of GML that are fundamental to the geological sciences including geometry, coverages, observations, reference systems and temporality. These constructs are then employed in a series of simple geological case studies including structural geological description, surficial geology, representation of geological time scales, mineral occurrences, geohazards and geochemical reconnaissance.

Lithologic data from 40 DSDP, ODP, and IODP scientific ocean drilling cores from the Pacific and North Atlantic oceans are the basis for an inquiry-based classroom exercise module for college introductory geology and oceanography courses. Part 1 of this exercise module is designed as an initial inquiry aimed at drawing out student beliefs and prior knowledge. In Parts 2-3 students observe and describe the physical characteristics of sediment cores using digital core photos, and determine the sediment composition using smear slide data and a decision tree. In Part 4 students combine their individual site data to construct a map showing the distribution of the primary marine sediment types of the Pacific and North Atlantic Oceans, and develop hypotheses to explain the distribution of the sediment types shown on their map. The transportable skills of observation, forming questions, plotting data, interpreting data, and scientific synthesis are embedded in this module, benefitting non-majors as well as majors. The exercise module was tested in the 2008 School of Rock program and the 2008 Urbino Summer School for Paleoceanography, and is currently being tested in undergraduate courses at James Madison University, North Hennipen Community College, St. Cloud State University and University of Massachusetts, Amherst in classes that range in size from 16 students to >150 students. The student worksheets, instructor guide, and preliminary evaluation data will be presented.

The USGS role in mapping the nation's submerged lands

USGS Publications Warehouse

Schwab, Bill; Haines, John

2004-01-01

The seabed provides habitat for a diverse marine life having commercial, recreational, and intrinsic value. The habitat value of the seabed is largely a function of the geological structure and related geological, biological, oceanologic, and geochemical processes. Of equal importance, the nation's submerged lands contain energy and mineral resources and are utilized for the siting of offshore infrastructure and waste disposal. Seabed character and processes influence the safety and viability of offshore operations. Seabed and subseabed characterization is a prerequisite for the assessment, protection, and utilization of both living and non-living marine resources. A comprehensive program to characterize and understand the nation's submerged lands requires scientific expertise in the fields of geology, biology, hydrography, and oceanography. The U.S. Geological Survey (USGS) has long experience as the Federal agency charged with conducting geologic research and mapping in both coastal and offshore regions. The USGS Coastal and Marine Geology Program (CMGP) leads the nation in expertise related to characterization of seabed and subseabed geology, geological processes, seabed dynamics, and (in collaboration with the National Oceanic and Atmospheric Administration (NOAA) and international partners) habitat geoscience. Numerous USGS studies show that sea-floor geology and processes determine the character and distribution of biological habitats, control coastal evolution, influence the coastal response to storm events and human alterations, and determine the occurrence and concentration of natural resources.

Oceanography of the Chilean Patagonia

Pantoja, Silvio; Luis Iriarte, José; Daneri, Giovanni

2011-03-01

Chilean Patagonia is one of the most extended fjord regions in the world that covers nearly 240,000 km 2 with an extremely complex coastline and topography in one of the least densely populated areas of the country (1-8 inhabitants every 10 km 2). In recent years, the area has been undergoing somewhat intense pressure since several commercial projects in hydroelectricity, tourism, and commercial salmon and mytilid cultures have been developed, or are in progress. Concomitantly, several large research programs have been devised to study the physical, chemical, and biological environment of Patagonia, such as the CIMAR FIORDO, and recently COPAS Sur-Austral based at Universidad de Concepcion, that attempts to close the bridge between oceanographic knowledge and its use by society. In this introductory article we summarize the collection of papers comprising this Special Issue of Continental Shelf Research. These papers deal with aspects of regional oceanography and geology, inorganic and organic geochemistry, ecology of pelagic and benthic organisms, and past changes in productivity.

The role of Internal Solitary Waves on deep-water sedimentary processes: the case of up-slope migrating sediment waves off the Messina Strait

NASA Astrophysics Data System (ADS)

Droghei, Riccardo; Falcini, Federico; Martorelli, Eleonora; Salusti, Ettore; Sannino, Gianmaria; Santoleri, Rosalia; Chiocci, Francesco

2015-04-01

In the last decade joint marine geology and physical oceanography studies are demonstrating the inherited connection between deep-water sedimentary processes and dynamics of water masses in a fruitful exchange in which bedforms type and geometry highlight slow or periodic bottom current processes or event of and oceanography explains and predicts morphological and sedimentary pattern at the seafloor. We investigate the presence of an intriguing up-slope migrating and rotating sand waves observed off the north entrance of the Messina Strait by taking into account the main oceanographic process occurring in the Strait, namely the presence of tidal induced internal solitary waves (ISWs). We hypothesize that the observed deflected pattern of these sand waves is due to refraction of wave occurring at the LIW-MAW interface and that the motion of the grains is due to the increased particle velocity field during the passage of ISWs. We modeled their formations and compared the results with the observed geometries of the dune field. Our findings suggest an intrinsic relationship between the dune filed and the presence of internal solitary waves, and provide some insights about their dynamics and migration rate as in accordance with previous measurements and analysis. We believe that our work represents an innovative and promising link between the geological and oceanographic communities, and gives some insights on the role of ISWs on sedimentary process.

Yost, E. F. (Principal Investigator)

1975-01-01

The author has identified the following significant results. The first part of the study resulted in photographic procedures for making multispectral positive images which greatly enhance the color differences in land detail using an additive color viewer. An additive color analysis of the geologic features near Willcox, Arizona using enhanced black and white multispectral positives allowed compilation of a significant number of unmapped geologic units which do not appear on geologic maps of the area. The second part demonstrated the feasibility of utilizing Skylab remote sensor data to monitor and manage the coastal environment by relating physical, chemical, and biological ship sampled data to S190A, S190B, and S192 image characteristics. Photographic reprocessing techniques were developed which greatly enhanced subtle low brightness water detail. Using these photographic contrast-stretch techniques, two water masses having an extinction coefficient difference of only 0.07 measured simultaneously with the acquisition of S190A data were readily differentiated.

Phylogeography and historical demography of the anadromous fish Leucopsarion petersii in relation to geological history and oceanography around the Japanese Archipelago.

PubMed

Kokita, Tomoyuki; Nohara, Kenji

2011-01-01

Phylogeographical patterns of marine and diadromous organisms are often influenced by dynamic ocean histories. For example, the marine realm around the Japanese Archipelago is an interesting area for phylogeographical research because of the wide variation in the environments driven by repeated shifts in sea level in the Quaternary. We analysed mitochondrial cyt b gene and nuclear myh6 gene sequences for individuals collected from throughout the range of the anadromous fish Leucopsarion petersii to assess the lineage divergence, phylogeographical pattern and historical demography in relation to geological history and oceanographic features around the archipelago. Leucopsarion petersii has two major lineages (the Japan Sea and Pacific Ocean lineages), which diverged during the late-early to middle Pleistocene. Geographical distributions of the two lineages were closely related to the pathways of the two warm currents, the Tsushima Current and the Kuroshio Current, that flow past the archipelago. Evidence of introgressive hybridization between these lineages was found at two secondary contact zones. Demographic tests suggested that the Japan Sea and Pacific Ocean lineages carried the genetic signal of different historical demographic processes, and these signals are probably associated with differences in habitat stability during recent glacial periods. The Japan Sea lineage has a larger body-size and more vertebrae, probably in relation to severe habitat conditions through Pleistocene climatic oscillations. Thus, the two lineages have long independent evolutionary histories, and the phylogeographical structure and demography of this species have been influenced both by historical events and the present-day oceanography around the Japanese Archipelago. © 2010 Blackwell Publishing Ltd.

Science program for an imaging radar receiving station in Alaska. Report of the science working group

NASA Technical Reports Server (NTRS)

1983-01-01

It is argued that there would be broad scientific benefit in establishing in Alaska an imaging radar receiving station that would collect data from the European Space Agency's Remote Sensing Satellite, ERS-1. This station would acquire imagery of the ice cover from the American territorial waters of the Beaufort, Chukchi, and Bering Seas. This station, in conjunction with similar stations proposed for Kiruna, Sweden, and Prince Albert, Canada would provide synoptic coverage of nearly the entire Arctic. The value of such coverage to aspects of oceanography, geology, glaciology, and botany is considered.

Dullo, Wolf-Christian; Pfaffl, Fritz A.

2017-09-01

Karl Andrée began studying questions of sedimentology and oceanography in 1908 when working as an assistant at the University of Marburg and he remained faithful to these subjects until his death in 1959. The vast majority of his scientific contributions, however, were published during his time at the University of Königsberg (1915-1945). There he published his fundamental papers on marine geology, all of which adhered strictly to the principles of uniformitarianism, and helped improve our understanding of sedimentary processes and the stratigraphic record. His scientific work has enormous breadth. In the course of 55 years, he published 124 individual papers and books, some of which became classic textbooks. His versatility is particularly evident in his book "Geology of the Seafloor", which contains many pertinent observations and descriptions still relevant today, even if it has fallen out of fashion. This scientist and university teacher was the first to successfully present the huge field of marine geology in all its facet and to consider the deposition of marine sediments as a function of their geographical distribution.

Offshore survey provides answers to coastal stability and potential offshore extensions of landslides into Abalone Cove, Palos Verdes peninsula, Calif

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

Dill, R.F.; Slosson, J.E.

1993-04-01

The configuration and stability of the present coast line near Abalone Cove, on the south side of Palos Verdes Peninsula, California is related to the geology, oceanographic conditions, and recent and ancient landslide activity. This case study utilizes offshore high resolution seismic profiles, side-scan sonar, diving, and coring, to relate marine geology to the stability of a coastal region with known active landslides utilizing a desk top computer and off-the-shelf software. Electronic navigation provided precise positioning that when applied to computer generated charts permitted correlation of survey data needed to define the offshore geology and sea floor sediment patterns. Amore » mackintosh desk-top computer and commercially available off-the-shelf software provided the analytical tools for constructing a base chart and a means to superimpose template overlays of topography, isopachs or sediment thickness, bottom roughness and sediment distribution patterns. This composite map of offshore geology and oceanography was then related to an extensive engineering and geological land study of the coastal zone forming Abalone Cove, an area of active landslides. Vibrocoring provided ground sediment data for high resolution seismic traverses. This paper details the systems used, present findings relative to potential landslide movements, coastal erosion and discuss how conclusions were reached to determine whether or not onshore landslide failures extend offshore.« less

Halpern, J. B.

2015-12-01

The STEMWiki Hyperlibrary Project is a collaborative effort directed by Prof. Delmar Larsen of UC Davis to replace printed textbooks with a no-fee, high quality, on line textbook environment for STEM courses and informal education. Instructors can build textbooks for their students by linking modules in the Hyperlibrary, write their own texts or use those built by others. The flexibility of the Hyperlibrary allows instructors to address the needs of diverse students in all types of institutions. At present over 4 million people per month visit the site, which makes it a primary global source of STEM educational material. The seed was the ChemWiki, which is the most developed, but there is also a GeoWiki that is being used for courses on Structural Geology, Sediments and Strata and Oceanography at UC Davis as well as including core components on geochemistry, geophysics, mineralogy, oceanography, paleobiology, paleoenvironments, petrology and plate tectonics. In addition to using and contributing to the GeoWiki, AGU members can participate in the other STEMWikis by writing (or editing) core components that involve geophysical topics and make use of the core components in the other areas for their teaching. The GeoWiki can be accessed at http://geowiki.ucdavis.edu/

Using Oceanography to Support Active Learning

NASA Astrophysics Data System (ADS)

Byfield, V.

2012-04-01

Teachers are always on the lookout for material to give their brightest students, in order to keep them occupied, stimulated and challenged, while the teacher gets on with helping the rest. They are also looking for material that can inspire and enthuse those who think that school is 'just boring!' Oceanography, well presented, has the capacity to do both. As a relatively young science, oceanography is not a core curriculum subject (possibly an advantage), but it draws on the traditional sciences of biology, chemistry, physic and geology, and can provide wonderful examples for teaching concepts in school sciences. It can also give good reasons for learning science, maths and technology. Exciting expeditions (research cruises) to far-flung places; opportunities to explore new worlds, a different angle on topical debates such as climate change, pollution, or conservation can bring a new life to old subjects. Access to 'real' data from satellites or Argo floats can be used to develop analytical and problem solving skills. The challenge is to make all this available in a form that can easily be used by teachers and students to enhance the learning experience. We learn by doing. Active teaching methods require students to develop their own concepts of what they are learning. This stimulates new neural connections in the brain - the physical manifestation of learning. There is a large body of evidence to show that active learning is much better remembered and understood. Active learning develops thinking skills through analysis, problem solving, and evaluation. It helps learners to use their knowledge in realistic and useful ways, and see its importance and relevance. Most importantly, properly used, active learning is fun. This paper presents experiences from a number of education outreach projects that have involved the National Oceanography Centre in Southampton, UK. All contain some element of active learning - from quizzes and puzzles to analysis of real data from satellites and Argo floats - all combined with background information about the Ocean. Many also aim to inspire and enthuse, by bringing in the human and personal, for example through blogs and Q/A sessions. This presentation takes a look at what has worked, and what may perhaps have been a little less successful.

Multispectral Resource Sampler Workshop

NASA Technical Reports Server (NTRS)

1979-01-01

The utility of the multispectral resource sampler (MRS) was examined by users in the following disciplines: agriculture, atmospheric studies, engineering, forestry, geology, hydrology/oceanography, land use, and rangelands/soils. Modifications to the sensor design were recommended and the desired types of products and number of scenes required per month were indicated. The history, design, capabilities, and limitations of the MRS are discussed as well as the multilinear spectral array technology which it uses. Designed for small area inventory, the MRS can provide increased temporal, spectral, and spatial resolution, facilitate polarization measurement and atmospheric correction, and test onboard data compression techniques. The advantages of using it along with the thematic mapper are considered.

One way to better engage K-16 students with the earth sciences is through classroom demonstrations with food. We summarize references from journals and the world wide web that use food to illustrate earth science concepts. Examples of how edible substances have been used include using candy bars to demonstrate weathering concepts, ice cream to mimic glaciers, and grapes to demonstrate evaporation. We also categorize these demonstrations into geology, weather, space science, and oceanography categories. We further categorize the topics by grade level, web versus traditional print format, amount of time necessary to prepare a lesson plan, and whether the activity is better used as a demonstration or hands on activity.

Morakis, J. C.; Cote, C. E.

1973-01-01

Satellite location and data collection systems development began in the early 1960's in NASA and the French CNES. These systems were initially developed for application to meteorology and oceanography as a means of tracking moving platforms on a global scale. Additional applications such as geology, hydrology, and ecology have since evolved. To date, five successful missions have been completed. With each successive launch, systems improved in accordance with user requirements - particularly reduction in cost and complexity of platform equipment. With planned launches, facilities will be available to the user community through 1980; NASA is currently forecasting needs beyond 1980.

Biological Oceanography

NASA Astrophysics Data System (ADS)

Dyhrman, Sonya

2004-10-01

The ocean is arguably the largest habitat on the planet, and it houses an astounding array of life, from microbes to whales. As a testament to this diversity and its importance, the discipline of biological oceanography spans studies of all levels of biological organization, from that of single genes, to organisms, to their population dynamics. Biological oceanography also includes studies on how organisms interact with, and contribute to, essential global processes. Students of biological oceanography are often as comfortable looking at satellite images as they are electron micrographs. This diversity of perspective begins the textbook Biological Oceanography, with cover graphics including a Coastal Zone Color Scanner image representing chlorophyll concentration, an electron micrograph of a dinoflagellate, and a photograph of a copepod. These images instantly capture the reader's attention and illustrate some of the different scales on which budding oceanographers are required to think. Having taught a core graduate course in biological oceanography for many years, Charlie Miller has used his lecture notes as the genesis for this book. The text covers the subject of biological oceanography in a manner that is targeted to introductory graduate students, but it would also be appropriate for advanced undergraduates.

United States Geological Survey Yearbook, fiscal year 1978

,

1979-01-01

Fiscal year 1978 saw the U.S. Geological Survey continuing to perform its basic historical missions of collecting, analyzing, and disseminating information about the Earth, its processes, and its water and mineral resources. Classifying Federal lands and supervising lessee mineral extraction operations on those lands were also major Survey concerns during the year. In addition, substantial progress was made in the exploration and assessment of the petroleum potential of the National Petroleum Reserve in Alaska, a recently assigned mission. These basic missions found expression in a wide range of program activities and interests as diverse as the sands of Mars and the volcanoes of Hawaii. Programs included assessment of numerous potential energy and mineral resources, study of earthquakes and other geologic hazards, appraisal of the magnitude and quality of the Nation's water resources, and supervision of lease operations on Federal lands. The Survey also was involved in developing data on land use and producing topographic, geologic, and hydrologic maps for public and private use. In cooperation with other Federal agencies, the Survey participated in studies under the U.S. Climate Program and continued its analysis of data received from the two Viking landers on the surface of Mars. On April 3, 1978, Dr. H. William Menard became the 10th Director of the U.S. Geological Survey. Dr. Menard, who, until his appointment, was Professor of Geology at the Scripps Institution of Oceanography, San Diego, Calif., brings to the Director's post the experience gained in a long and successful career as a marine geologist and oceanographer. He succeeds Dr. Vincent E. McKelvey, who continues with the Survey as a senior research scientist.

The ARMADA Project: Bringing Oceanography and the Arctic to the Midwest

NASA Astrophysics Data System (ADS)

Pazol, J.

2010-12-01

In the fall of 2009, I spent 6 weeks aboard the Coast Guard Icebreaker Healy on a mapping expedition in the Arctic Ocean, through participation in the University of Rhode Island's ARMADA Project. Because I grew up in the Midwest, went to college here, and teach in the Chicago suburbs, I had limited first-hand experience in oceanography, as did most of my students. During my time aboard the ship, I primarily served as a member of the mapping team, collecting bathymetric and seismic data. My other science activities included aiding geologists and acoustic engineers in dredging projects and deployment of under-ice recording devices. I collected water data, sent off weather balloons, and assisted marine mammal observers. For the ARMADA Project I kept an on-line journal, which had a far-reaching impact. Students in many schools kept track of my activities and communicated with me via e-mail. Colleagues and friends shared the journal through other media, such as Facebook. Several of my entries were published in blogs belonging to NOAA and the USGS. I received a grant for renting a satellite phone, and through it was able to make "Live from the Arctic" phone calls. After introductory PowerPoints I communicated with more than 420 students in 5 schools in 3 states. When I returned, I made a series of presentations about the Arctic and my adventures to hundreds of people and was featured in an educational magazine with a circulation of more than 90,000. I also participated in an in-depth mentoring program with a new teacher to help her succeed during the first years of her career. The results: My students and I now have a direct connection to the Arctic and to the fields of oceanography, acoustic engineering, and geology. On their own initiative, students have developed individual projects exploring aspects of my research. They have attended presentations from the Extreme Ice Center and have become involved in drilling issues in the Chukchi Sea. A group of students is exploring the possibility of working with scientists from Scripps Institution of Oceanography to analyze the acoustic data. These are just some of the ways that a teacher's research experience can be effectively translated into the classroom setting.

The Nimbus satellites - Pioneering earth observers

NASA Technical Reports Server (NTRS)

White, Carolynne

1990-01-01

The many scientific achievements of the Nimbus series of seven satellites for low-altitude atmospheric research and global weather surveillance are reviewed. The series provides information on fishery resources, weather modeling, atmospheric pollution monitoring, earth's radiation budget, ozone monitoring, ocean dynamics, and the effects of cloudiness. Data produced by the forty-eight instruments and sensors flown on the satellites are applied in the fields of oceanography, hydrology, geology, geomorphology, geography, cartography, agriculture and meteorology. The instruments include the Coastal Zone Color Scanner (which depicts phytoplankton concentrations in coastal areas), the Scanning Multichannel Microwave Radiometer (which measures sea-surface temperatures and sea-surface wind-speed), and the Total Ozone Mapping Spectrometer (which provides information on total amounts of ozone in the earth's atmosphere).

Water problems in the present trend towards greater aridity

USGS Publications Warehouse

Leopold, Luna Bergere; Craig, Harmon

1957-01-01

In the past few days we have heard a number of scientists, gathered here at Scripps Institution of Oceanography, discuss research work which, in one manner or another, bears on problems related to water resources. They have been discussing, particularly, problems in the field of climatology, and have speculated on the meaning of the results of this research. One of the problems under discussion was the nature, and possible cause, of the climatic fluctuation which we have experienced in recent decades, and its relation to climatic changes in recent geologic time since the last glaciation. These discussions have given me the courage, or perhaps the recklessness, to indulge in some speculation relative to various aspects of water resource problems in the United States.

2018-02-01

Operational oceanography requires the quantity, quality, and availability of data set and the timeliness and effectiveness of data products. Without steady and strong operational system supporting, operational oceanography will never be proceeded far. In this paper we describe an integrated platform named Argo Workstation. It operates as a data processing and management system, capable of data collection, automatic data quality control, visualized data check, statistical data search and data service. After it is set up, Argo workstation provides global high quality Argo data to users every day timely and effectively. It has not only played a key role in operational oceanography but also set up an example for operational system.

Applications of remote sensing data to the Alaskan environment

NASA Technical Reports Server (NTRS)

Belon, A. E.; Iller, J. M.

1973-01-01

The ERTS program provides a means to overcome the formidable logistic and economic costs of preparing environmental surveys of the vast and relatively unexplored regions of Alaska. There is an excellent potential in satellite remote sensing to benefit Federal, state, local, and private agencies, by providing a new synoptic data base which is necessary for the preparation of the needed surveys and the search for solutions to environmental management problems. One approach in coupling satellite data to Alaskan problems is a major program initiated by the University of Alaska and funded by NASA's Goddard Space Flight Center. This included 12 projects whose aims were to study the feasibility of applying ERTS data to the disciplines of ecology, agriculture, hydrology, wildlife management, oceanography, geology, glaciology, volcanology, and archaeology.

John Murray / MABAHISS expedition versus the International Indian Ocean Expedition (IIOE) in retrospect

NASA Astrophysics Data System (ADS)

Aleem, A. A.; Morcos, S. A.

In addition to its scientific achievements, the John Murray/Mabahiss Expedition was a unique experiment in technology transfer and it pioneered bilateral relations in the field of oceanography, at a time when the Law of the Sea was not even an embryonic concept. The Expedition will be remembered for its profound influence on the development of oceanography in Egypt, and subsequently in several Arab and African countries, as well as for its socio-economic impact in Egypt. The International Indian Ocean Expedition (IIOE) was an elaborate exercise involving both the most sophisticated developments in oceanography of the day and the full complexity of international relations which necessitated the scientific, coordinating and supporting mechanisms of SCOR, IOC and Unesco combined. Each exercise separated by 25 years represented a significant event in the development of oceanography. Each was a natural product of the prevailing state of the art and the international climate. Oceanography had made a quantum jump in technology in the intervening quarter of a century, which had put the cost of deep sea oceanography quite beyond the financial capabilities of many developing countries, an important factor to bear in mind when comparing the impact of the John Murray/Mabahiss Expedition on Egypt with that of the IIOE, on the Indian Ocean countries.

Using Geophysical Data in the Texas High School Course, Geology, Meteorology, and Oceanography

NASA Astrophysics Data System (ADS)

Ellins, K.; Olson, H.; Pulliam, J.; Schott, M. J.

2002-12-01

Science educators working directly with scientists to develop inquiry-based instructional materials in Earth science yield some of the best results. The TEXTEAMS (Texas Teachers Empowered for Achievement in Mathematics and Science) Leadership Training for the Texas high school science course, Geology, Meteorology and Oceanography (GMO) is one example of a successful program that provides high-quality training to master teachers using geophysical data collected by scientists at The University of Texas Institute for Geophysics (UTIG). TEXTEAMS is a certification program of professional development and leadership training sponsored by the National Science Foundation that is part of the Texas Statewide Systemic Initiative. UTIG scientists teamed with science educators at the Charles A. Dana Center for Mathematics and Science Education at UT and the Texas Education Agency to develop inquiry-based instructional materials for eight GMO modules. Our learning activities help students and teachers understand how Earth scientists interpret the natural world and test their hypotheses, and provide opportunities for the use of technology in classroom science learning; they are aligned with national and state teaching standards. Examples of TEXTEAMS GMO learning activities that use geophysical data. 1. Neotectonics: radiocarbon dates and elevation above current sea level of raised coral reefs in the New Georgia Islands are used to calculate rates of tectonic uplift and as a basis for the development of a conceptual model to explain the pattern of uplift that emerges from the data. 2. Large Igneous Provinces:geophysical logging data collected on ODP Leg 183 (Kerguelen Plateau) are analyzed to identify the transition from sediment to basement rock. 3. The Search for Black Gold: petroleum exploration requires the integration of geology, geophysics, petrophysics and geochemistry. Knowledge gained in previous GMO modules is combined with fundamental knowledge about economics to construct a petroleum prospect for a small oil and gas company. TEXTEAMS GMO Leadership Training uses mentoring of teachers by fellow teachers to implement effective teaching strategies and rigorous science curricula. More than 75 GMO teachers participated in the institutes and they in turn have trained about 2,250 other teachers. The number of students reached is about 67,500. The success of the GMO institutes have led to new partnerships between scientists and educators, and allowed UTIG to secure additional funds to promote K-12 Earth science education in Texas. They can serve as a template for other programs that are relevant to local communities and which utilize geophysical data and science.

Utilizing social media for informal ocean conservation and education: The BioOceanography Project

NASA Astrophysics Data System (ADS)

Payette, J.

2016-02-01

Science communication through the use of social media is a rapidly evolving and growing pursuit in academic and scientific circles. Online tools and social media are being used in not only scientific communication but also scientific publication, education, and outreach. Standards and usage of social media as well as other online tools for communication, networking, outreach, and publication are always in development. Caution and a conservative attitude towards these novel "Science 2.0" tools is understandable because of their rapidly changing nature and the lack of professional standards for using them. However there are some key benefits and unique ways social media, online systems, and other Open or Open Source technologies, software, and "Science 2.0" tools can be utilized for academic purposes such as education and outreach. Diverse efforts for ocean conservation and education will continue to utilize social media for a variety of purposes. The BioOceanography project is an informal communication, education, outreach, and conservation initiative created for enhancing knowledge related to Oceanography and Marine Science with an unbiased yet conservation-minded approach and in an Open Source format. The BioOceanography project is ongoing and still evolving, but has already contributed to ocean education and conservation communication in key ways through a concerted web presence since 2013, including a curated Twitter account @_Oceanography and BioOceanography blog style website. Social media tools like those used in this project, if used properly can be highly effective and valuable for encouraging students, networking with researchers, and educating the general public in Oceanography.

From satellite altimetry to Argo and operational oceanography: three revolutions in oceanography

NASA Astrophysics Data System (ADS)

Le Traon, P. Y.

2013-10-01

The launch of the French/US mission Topex/Poseidon (T/P) (CNES/NASA) in August 1992 was the start of a revolution in oceanography. For the first time, a very precise altimeter system optimized for large-scale sea level and ocean circulation observations was flying. T/P alone could not observe the mesoscale circulation. In the 1990s, the ESA satellites ERS-1/2 were flying simultaneously with T/P. Together with my CLS colleagues, we demonstrated that we could use T/P as a reference mission for ERS-1/2 and bring the ERS-1/2 data to an accuracy level comparable to T/P. Near-real-time high-resolution global sea level anomaly maps were then derived. These maps have been operationally produced as part of the SSALTO/DUACS system for the last 15 yr. They are now widely used by the oceanographic community and have contributed to a much better understanding and recognition of the role and importance of mesoscale dynamics. Altimetry needs to be complemented with global in situ observations. At the end of the 90s, a major international initiative was launched to develop Argo, the global array of profiling floats. This has been an outstanding success. Argo floats now provide the most important in situ observations to monitor and understand the role of the ocean on the earth climate and for operational oceanography. This is a second revolution in oceanography. The unique capability of satellite altimetry to observe the global ocean in near-real-time at high resolution and the development of Argo were essential for the development of global operational oceanography, the third revolution in oceanography. The Global Ocean Data Assimilation Experiment (GODAE) was instrumental in the development of the required capabilities. This paper provides an historical perspective on the development of these three revolutions in oceanography which are very much interlinked. This is not an exhaustive review and I will mainly focus on the contributions we made together with many colleagues and friends.

They are now widely used by the oceanographic community and have contributed to a much better understanding and recognition of the role and importance of mesoscale dynamics. Altimetry needs to be complemented with global in situ observations. In the end of the 90s, a major international initiative was launched to develop Argo, the global array of profiling floats. This has been an outstanding success. Argo floats now provide the most important in situ observations to monitor and understand the role of the ocean on the earth climate and for operational oceanography. This is a second revolution in oceanography. The unique capability of satellite altimetry to observe the global ocean in near real time at high resolution and the development of Argo were essential to the development of global operational oceanography, the third revolution in oceanography. The Global Ocean Data Assimilation Experiment (GODAE) was instrumental in the development of the required capabilities. This paper provides an historical perspective on the development of these three revolutions in oceanography which are very much interlinked. This is not an exhaustive review and I will mainly focus on the contributions we made together with many colleagues and friends.

Understanding the deep-sea ecosystem functioning is a key issue in the study of ocean sciences. Bringing together researchers from several scientific domains, the BIOMETORE project aims to the increase knowledge on deep-sea ecosystems and biodiversity at the Atlantic seamounts of the Madeira-Tore and Great Meteor geological complexes. The project outputs will provide important information for the understanding and sustainable management of the target seamount ecosystems, thus contributing to fulfill knowledge gaps on their biodiversity, from bacteria to mammals, and food webs, as well as to promote future sustainable fisheries and sea-floor integrity. The plan includes the realization of eight multidisciplinary surveys, four done during the summer of 2015 and another four planned for the same season of 2016, in target seamounts: the Gorringe bank, the Josephine, and others in the Madeira-Tore, and selected ones in the Greta Meteor (northeastern Atlantic Ocean). The surveys cover a number of scientific areas in the domains of oceanography, ecology, integrative taxonomy, geology, fisheries and spatial mapping. We present and discuss BIOMETORE developments, the preliminary results from the four 2015 summer surveys, and the planning of the next four surveys.

Marine and Aquatic Research Experience: A Program for Undergraduates Studying Estuaries

2001-05-01

Since 1998, the Marine and Aquatic Research Experience (MARE) Program for Undergraduates has been conducting an on-going ecological and oceanographic survey of a coastal plain estuary, Winyah Bay, SC. MARE is a student-generated, faculty-guided model for hands-on research designed to apply classroom learning to real world applications. The overall goal of MARE is to create field-based learning opportunities for students while at the same time encouraging them to become scientists and to practice being scientists from conception to planning, to execution, to presentation of scientific research. To achieve this goal students work in "crews" within MARE which try to answer specific questions about the estuary. These crews share resources, ideas, and data with each other to produce a comprehensive database for the estuary. Involvement in MARE is strictly voluntary and not a requirement of a degree program. Also, MARE was established as part of the student natural interests and not as part of a professor's regular research. Another important feature of MARE is ownership. The research done and efforts made belong to the members of MARE. Although the role of faculty involvement in MARE is important through the use of their expertise, equipment, laboratories, and funding, the students are fundamentally responsible for organizing, conducting, and managing their own scientific investigations. However, along with this ownership of the scientific products of MARE comes responsibility for any mistakes made. In this sense the MARE members learn from real, not classroom mistakes. The ability to prepare for and deal with frustration and adversity in real-world situations is also an important component of MARE. The MARE research effort has been broken into crews with specific scientific directions. The biological oceanography crew has been primarily concerned with determining the species diversity of the Winyah Bay ecosystem. The physical oceanography and suspended sediment crews are trying to understanding the circulation and mixing of water masses and suspended matter throughout the estuary. The chemical oceanography crew has focused on the concentration and dynamics of nutrients. Recent additions to MARE include a geological processes crew and a remote sensing crew. An overview of the results to date and future research directions will be displayed and discussed.

Graduate students in oceanography: Recruitment, success, and career prospects

NASA Astrophysics Data System (ADS)

Nowell, Arthur R. M.; Hollister, Charles D.

Graduate education, student quality, stipend support, and subsequent employment form a triad of concern to many oceanographers. While the number of graduate degree programs in oceanography in the U.S. exceeds 50, remarkably few data are available on numbers of student applications, student survival rates, the quality of the applicants and accepted students, and their subsequent employment.Consequently, most discussions within an institution are based on data from a single school, while most statements made to federal government program managers by scientists are based on personal perceptions and feelings. With the emerging global initiatives, which are very labor intensive, it appears appropriate to ask, “Is there an impending crisis in graduate education in oceanography?” Widespread concern about availability of new talent, the quality of incoming students, and the overall national crisis in science and engineering student recruitment has led many scientists to state that oceanography has widespread problems in terms of student numbers and, more importantly, quality. Often, when a scientist does not find a student in the spring application rites, the scientist declares there is a national shortage of well-qualified students. Moreover, in certain subdisciplines of the field (e.g., physical oceanography) the crisis is perceived as severe and immediate, though as we shall see, physical oceanography is in an improving mode and is also experiencing an interesting increase in the numbers of well-qualified women applicants.

Oceanography: the present and future

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

Brewer, P.G.

This volume is the proceedings of a symposium held September 29 to October 2, 1980 at Woods Hole, Massachusetts, commemorating the 50th anniversary of the founding of the Woods Hole Oceanographic Institution. The book is the companion volume to ''Oceanography: the Past'' also published by Springer-Verlag. The papers are organized not by conventional disciplinary topics but by the ''scale'' of the oceanographic process: Part I, Small and Local Scale Oceanography; Part II, Regional Scale Oceanography; Part III, Global Scale Oceanography; and Part IV, The Human Scale. The articles presented, however, do not summarize such projects but give recognizable disciplinary summariesmore » and predictions in line with the subtitle of the book. In general, the articles are classed by this scale concept, although ''Shoreline Research'' by Pilkey and ''The Oceans Nearby'' by Murphy are better placed in the section The Human Scale and Bolin's ''Changing Global Biogeochemistry'' switched from The Human Scale to Global Scale as indicated by the title. This volume should be of value to marine geologists and geochemists, sedimentologists, and public-interest (environmental) geologists interested in oceanographic processes.« less

SIG Contribution in the Making of Geotechnical Maps in Urban Areas

NASA Astrophysics Data System (ADS)

Monteiro, António; Pais, Luís Andrade; Rodrigues, Carlos; Carvalho, Paulo

2017-10-01

The use of Geographic Information Systems (GIS) has spread to several science areas, from oceanography to geotechnics. Its application in the urban mapping was intensified in the last century, which allowed a great development, due to the use of geographic database, new analysis tools and, more recently, free open source software. Geotechnical cartography struggle with a permanent and large environment re-organization in urban area, due to new building construction, trenching and the drilling of sampling wells and holes. This creates an extra important and largest volume of data at any pre-existence geological map. The main problem results on the fact that the natural environment is covered with buildings and communications system. The purpose of this work is to create a viable geographic information base for geotechnical mapping through a free GIS computer program and open source, with non-traditional cartographic sources, giving preference to open platforms. QGIS was used as software and “Google Maps”, “Bing Maps” and “OpenStreetMap” were applied as cartographic sources using the “OpenLayers plugin” module. Finally, we also pretend to identify and delimit the degree of granite’s change and fracturing areas using a “Streetview” platform. This model has cartographic input which are a geological map study area, open cartographic web archives and the use of “Streetview” platform. The output has several layouts, such as topography intersection (roads, borders, etc.), with geological map and the bordering area of Guarda Urban Zone. The use of this platform types decrease the collect data time and, sometimes, a careful observation of pictures that were taken during excavations may reveal important details for geological mapping in the study area.

Contribution of the "Institut Scientifique Chérifien" to the development of geoscientific research in Northwest Africa since its creation in 1914

NASA Astrophysics Data System (ADS)

Medina, F.

2013-08-01

The contribution of the "Institut Scientifique Chérifien", the oldest scientific research centre in Morocco, is reviewed since its creation almost a century ago. Planned in 1914 by the French protectorate of Morocco, this institute has played, since its effective creation in 1920, an important role in the development of several geosciences in North Africa, such as meteorology and climatology, geophysics (gravimetry, magnetism and especially seismology), geomorphology, geology and oceanography. After the independence of Morocco in 1955, several activities, such as meteorology, were transferred elsewhere, but others, such as seismology and magnetism, remained important elements of the centre until recent years. In addition to the research activities, its observatories and libraries that were built during the early years are unique in Northwest Africa.

The German airplane program for earth scientific research supports the work of a vast staff of earth scientists from universities and federal agencies. Due to their fields of interest, which are in oceanography, hydrology, geology, ecology, and forestry, five test areas were selected which are spread all over Germany. The sensor package, which was designed in accordance with the requirements of this group of scientists, will be installed in a DO 28 D2 type airplane. The sensor equipment consists of a series of 70-mm cameras having different film/filter combinations, a photogrammetric camera, an infrared radiometer, an 11-channel multispectral line scanner, a LANDSAT-compatible radiometer, and a complex avionic system. Along with the airplane, a truck will be equipped with a set of radiometers and other sensor devices for extensive ground-truth measurement; this also includes a cherry picker.

Biogenic Mn-Oxides in Subseafloor Basalts

Ivarsson, Magnus; Broman, Curt; Gustafsson, Håkan; Holm, Nils G.

2015-01-01

The deep biosphere of the subseafloor basalts is recognized as a major scientific frontier in disciplines like biology, geology, and oceanography. Recently, the presence of fungi in these environments has involved a change of view regarding diversity and ecology. Here, we describe fossilized fungal communities in vugs in subseafloor basalts from a depth of 936.65 metres below seafloor at the Detroit Seamount, Pacific Ocean. These fungal communities are closely associated with botryoidal Mn oxides composed of todorokite. Analyses of the Mn oxides by Electron Paramagnetic Resonance spectroscopy (EPR) indicate a biogenic signature. We suggest, based on mineralogical, morphological and EPR data, a biological origin of the botryoidal Mn oxides. Our results show that fungi are involved in Mn cycling at great depths in the seafloor and we introduce EPR as a means to easily identify biogenic Mn oxides in these environments. PMID:26107948

Earth Science Curriculum Enrichment Through Matlab!

NASA Astrophysics Data System (ADS)

Salmun, H.; Buonaiuto, F. S.

2016-12-01

The use of Matlab in Earth Science undergraduate courses in the Department of Geography at Hunter College began as a pilot project in Fall 2008 and has evolved and advanced to being a significant component of an Advanced Oceanography course, the selected tool for data analysis in other courses and the main focus of a graduate course for doctoral students at The city University of New York (CUNY) working on research related to geophysical, oceanic and atmospheric dynamics. The primary objectives of these efforts were to enhance the Earth Science curriculum through course specific applications, to increase undergraduate programming and data analysis skills, and to develop a Matlab users network within the Department and the broader Hunter College and CUNY community. Students have had the opportunity to learn Matlab as a stand-alone course, within an independent study group, or as a laboratory component within related STEM classes. All of these instructional efforts incorporated the use of prepackaged Matlab exercises and a research project. Initial exercises were designed to cover basic scripting and data visualization techniques. Students were provided data and a skeleton script to modify and improve upon based on the laboratory instructions. As student's programming skills increased throughout the semester more advanced scripting, data mining and data analysis were assigned. In order to illustrate the range of applications within the Earth Sciences, laboratory exercises were constructed around topics selected from the disciplines of Geology, Physics, Oceanography, Meteorology and Climatology. In addition the structure of the research component of the courses included both individual and team projects.

The questions that chemical oceanographers prioritize over the coming decades, and the methods we use to address these questions, will define our field's contribution to 21st century science. In recognition of this, the U.S. National Science Foundation and National Oceanic and Atmospheric Administration galvanized a community effort (the Chemical Oceanography MEeting: A BOttom-up Approach to Research Directions, or COME ABOARD) to synthesize bottom-up perspectives on selected areas of research in Chemical Oceanography. Representing only a small subset of the community, COME ABOARD participants did not attempt to identify targeted research directions for the field. Instead, we focused on how best to foster diverse research in Chemical Oceanography, placing emphasis on the following themes: strengthening our core chemical skillset; expanding our tools through collaboration with chemists, engineers, and computer scientists; considering new roles for large programs; enhancing interface research through interdisciplinary collaboration; and expanding ocean literacy by engaging with the public. For each theme, COME ABOARD participants reflected on the present state of Chemical Oceanography, where the community hopes to go and why, and actionable pathways to get there. A unifying concept among the discussions was that dissimilar funding structures and metrics of success may be required to accommodate the various levels of readiness and stages of knowledge development found throughout our community. In addition to the science, participants of the concurrent Dissertations Symposium in Chemical Oceanography (DISCO) XXV, a meeting of recent and forthcoming Ph.D. graduates in Chemical Oceanography, provided perspectives on how our field could show leadership in addressing long-standing diversity and early-career challenges that are pervasive throughout science. Here we summarize the COME ABOARD Meeting discussions, providing a synthesis of reflections and perspectives on the field.

An oceanography summer school in Ghana, West Africa

NASA Astrophysics Data System (ADS)

Arbic, B. K.; Ansong, J. K.; Johnson, W.; Nyadjro, E. S.; Nyarko, E.

2016-02-01

Because oceanography is a global science, it clearly benefits from the existence of a world-wide network of oceanographers. As with most STEM disciplines, sub-Saharan Africa is not as well represented in the field of oceanography as it should be, given its large population. The need for oceanographers in sub-Saharan Africa is great, due to a long list of ocean-related issues affecting African development, including but not limited to fishing, oil drilling, sea level rise, coastal erosion, shipping, and piracy. We view this as an opportunity as well as a challenge. Many of the world's fastest growing economies are in sub-Saharan Africa, and STEM capacity building could further fuel this growth. With support from the US National Science Foundation, we ran an oceanography summer school from August 24-27, 2015, at the Regional Maritime University (RMU) in Ghana, West Africa. This first summer school was lecture-based, with a focus on basic chemical oceanography, basic physical oceanography, ocean modeling, and satellite oceanography. About 35 participants came to almost every lecture, and about 20 other participants came to some of the lectures as their time permitted. The participants included RMU faculty, 12 students from the Kwame Nkrumah University of Science and Technology, one Associate Oceanographer from the University of Ghana, and some participants from private sector companies and Ghanaian governmental agencies. There were long and lively discussions at the end of each lecture, and there was a lengthy discussion at the conclusion of the school on how to improve future summer schools. In 2016 and 2017, we plan to divide into smaller groups so that participants can pursue their particular interests in greater depth, and to allow time for student presentations. We also plan to begin exploring the potential for research partnerships, and to utilize distance learning to involve more faculty and students from locations throughout Ghana and perhaps from even other countries in sub-Saharan Africa.

MPOWIR Pattullo Conference; Charleston, South Carolina, 23-26 May 2010; Initiated in 2004, Mentoring Physical Oceanography Women to Increase Retention (MPOWIR) is a community-initiated and community-led program aimed at providing mentoring to junior women in physical oceanography to improve their retention in the field. The centerpiece of the MPOWIR program is the Pattullo Conference, a two-and-a-half-day mentoring event held biannually. The second conference was held in South Carolina. The conference is named for June Pattullo, the first woman to receive a Ph.D. in physical oceanography. The goals of the Pattullo Conference are to build community networks among junior and senior scientists, to provide junior scientists with feedback on their current and planned research projects, to provide advice to junior scientists on their career goals, to introduce both senior and junior scientists to aspects of professional development, and to raise awareness of issues confronting junior women among the senior scientist community.

Macroecology: A Primer for Biological Oceanography

NASA Astrophysics Data System (ADS)

Li, W. K. W.

2016-02-01

Macroecology is the study of ecological patterns discerned at a spatial, temporal, or organization scale higher than that at which the focal entities interact. Such patterns are statistical or emergent manifestations arising from the ensemble of component entities. Although macroecology is a neologism largely based in terrestrial and avian ecology, macroscopic patterns have long been recognised in biological oceanography. Familiar examples include Redfield elemental stoichiometry, Elton trophic pyramids, Sheldon biomass spectrum, and Margalef life-forms mandala. Macroecological regularities can often be found along various continua, such as along body size in power-law scaling or along habitat temperature in metabolic theory. Uniquely in oceanography, a partition of the world ocean continuum into Longhurst biogeochemical provinces provides a spatial organization well-suited for macroecological investigations. In this rational discrete approach, fundamental processes in physical and biological oceanography that differentiate a set of non-overlapping ocean regions also appear to shape the macroecological structure of phytoplankton communities.

Since 1914, the Spanish Institute of Oceanography (IEO) performs multidisciplinary studies of the marine environment. In same case are systematic studies and in others are specific studies for special requirements (El Hierro submarine volcanic episode, spill Prestige, others.). Different methodologies and data acquisition techniques are used depending on studies aims. The acquired data are stored and presented in different formats. The information is organized into different databases according to the subject and the variables represented (geology, fisheries, aquaculture, pollution, habitats, etc.). Related to physical and chemical oceanography data, in 1964 was created the DATA CENTER of IEO (CEDO), in order to organize the data about physical and chemical variables, to standardize this information and to serve the international data network SeaDataNet. www.seadatanet.org. This database integrates data about temperature, salinity, nutrients, and tidal data. CEDO allows consult and download the data. http://indamar.ieo.es On the other hand, related to data about marine species in 1999 was developed SIRENO DATABASE. All data about species collected in oceanographic surveys carried out by researches of IEO, and data from observers on fishing vessels are incorporated in SIRENO database. In this database is stored catch data, biomass, abundance, etc. This system is based on architecture ORACLE. Due to the large amount of information collected over the 100 years of IEO history, there is a clear need to organize, standardize, integrate and relate the different databases and information, and to provide interoperability and access to the information. Consequently, in 2000 it emerged the first initiative to organize the IEO spatial information in an Oceanography Information System, based on a Geographical Information System (GIS). The GIS was consolidated as IEO institutional GIS and was created the Spatial Data Infrastructure of IEO (IDEO) following trend of INSPIRE. All data included in the GIS have their corresponding metadata about ISO19115 and INSPIRE. IDEO is based on Web services, Quality of Services, Open standards, ISO (OGC) and INSPIRE standards, and both provide access to the geographical marine information of IEO. The GIS allows the information to be organized, visualized, consulted and analyzed. The data from different IEO databases are integrated into a GIS corporate Geodatabase (Esri format). This tool is essential in the decision making of aspects like: - Protection of marine environment - Sustainable management of resources - Natural Hazards. - Marine spatial planning. Examples of the use of GIS as a spatial analysis tool are: - Mud volcanoes explored in LIFE-INDEMARES project. - Cartographic series about Spanish continental shelf, developed from data integrated in IEO marine GIS, acquired from oceanographic surveys in ESPACE project. - Cartography developed from the information gathered in Initial Assessment of Marine Strategy Framework Directive. - Studies of natural hazards related to submarine canyons in southeast region marine Spanish. Currently the IEO is participating in many European initiatives, especially in several lots of EMODNET. The IEO besides is working in consonance with INSPIRE, Growth Blue, Horizon 2020, etc., to contribute to, the knowledge of marine environment, its protection and its spatial planning are extremely relevant issues. In order to facilitate the access to the Spatial Data Infrastructure of IEO, the IEO Geoportal was developed in 2012. It mainly involves a metadata catalog, access to the data viewers and Web Services of IDEO. http://www.geo-ideo.ieo.es/geoportalideo/catalog/main/home.page

Unique deep-water ecosystems off the southeastern United States

USGS Publications Warehouse

Ross, Steve W.

2007-01-01

If nothing else, research in deep-sea environments teaches us how little we know about such important and productive habitats. The relatively recent discovery of hydrothermal-vent and cold-seep ecosystems illustrates this paucity of knowledge, and the subsequent explosion of research on these systems is a good example of the impact such concentrated efforts can have on marine sciences (see the March 2007 special issue of Oceanography on InterRidge, and Levin et al., 2007). The recent surge of interest in deep-sea corals is another example of how focused research on a particular subject can result in new perspectives on continental slope biotopes. Although deep-sea corals have been known for over 200 years, they were viewed as somewhat of a novelty, and research on them was sporadic, typically geologic, and usually only documented their occurrences (e.g., Stetson et al., 1962; Neumann et al., 1977; Paull et al., 2000).

The Shuttle Imaging Radar B (SIR-B) experiment report

NASA Technical Reports Server (NTRS)

Cimino, Jo Bea; Holt, Benjamin; Richardson, Annie

1988-01-01

The primary objective of the SIR-B experiment was to acquire multiple-incidence-angle radar imagery of a variety of Earth's surfaces to better understand the effects of imaging geometry on radar backscatter. A complementary objective was to map extensive regions of particular interest. Under these broad objectives, many specific scientific experiments were defined by the 43 SIR-B Science Team members, including studies in the area of geology, vegetation, radar penetration, oceanography, image analysis, and calibration technique development. Approximately 20 percent of the planned digital data were collected, meeting 40 percent of the scientific objectives. This report is an overview of the SIR-B experiment and includes the science investigations, hardware design, mission scenario, mission operations, events of the actual missions, astronaut participation, data products (including auxiliary data), calibrations, and a summary of the actual coverage. Also included are several image samples.

Shuttle imaging radar views the Earth from Challenger: The SIR-B experiment

NASA Technical Reports Server (NTRS)

Ford, J. P.; Cimino, J. B.; Holt, B.; Ruzek, M. R.

1986-01-01

In October 1984, SIR-B obtained digital image data of about 6.5 million km2 of the Earth's surface. The coverage is mostly of selected experimental test sites located between latitudes 60 deg north and 60 deg south. Programmed adjustments made to the look angle of the steerable radar antenna and to the flight attitude of the shuttle during the mission permitted collection of multiple-incidence-angle coverage or extended mapping coverage as required for the experiments. The SIR-B images included here are representative of the coverage obtained for scientific studies in geology, cartography, hydrology, vegetation cover, and oceanography. The relations between radar backscatter and incidence angle for discriminating various types of surfaces, and the use of multiple-incidence-angle SIR-B images for stereo measurement and viewing, are illustrated with examples. Interpretation of the images is facilitated by corresponding images or photographs obtained by different sensors or by sketch maps or diagrams.

Application of remote sensing data to surveys of the Alaskan environment

Belon, A. E.; Miller, J. M.

1974-01-01

Coupling of satellite data to resource management problems in Alaska is implemented through feasibility studies of applicability of Landsat data to specific environmental surveys in ecology, agriculture, hydrology, wildlife management, oceanography, geology, etc.; and using the results of these studies to extend the benefits of satellite data applications to the operational needs of mission-oriented agencies of federal, state, and regional governments, as well as private industry. Activities designed to encourage the participation of users in the Landsat program at levels most appropriate to the users' interests are described and include: observation, coordination, and information exchange; training courses and workshops; data exchange; consulting services; data processing services; user participation in University research projects; and university participation in the operational projects of user agencies. Progress in these areas is reported. The effectiveness of this broad-based approach in overcoming the initial apprehensiveness of users is demonstrated.

Data collected with the Shuttle Imaging Radar-B (SIR-B) on the October 5, 1985 Shuttle mission are discussed. The design and capabilities of the sensor which operates in a fixed illumination geometry and has incidence angles between 15 and 60 deg with 1 deg increments are described. Problems encountered with the SIR-B during the mission are examined. the The radar stereo imaging capability of the sensor was verified and three-dimensional images of the earth surface were obtained. The oceanography experiments provided significant data on ocean wave and internal wave patterns, oil spills, and ice zones. The geological images revealed that the sensor can evaluate penetration effect in dry soil from buried receivers and the existence of subsurface dry channels in the Egyptian desert was validated. The use of multiincidence angle imaging to classify terrain units and derive vegetation maps and the development of terrain maps are confirmed.

"The Oceans" not Withstanding: Scripps Geological-Geophysical Expeditions of the Golden Age

Fisher, R. L.

2002-12-01

"The Oceans: Their Physics, Chemistry, and General Biology," fully recognized and promoted the inherent unity of oceanography, the field itself, and of all components of the oceanic world. It covered well the wet pieces. However, except for sedimentary studies of the California borderland and reconnaissances of the Arctic, Mediterranean, and the South Atlantic, little was presented that could be parent to today's portrayals of marine geology and geophysics. The advances in those areas in the 1950's, 1960's, and early 1970's, by SIO scientists and those of several other institutions resulted from extended expeditionary studies, essential on-the-job field training of confident very young chief scientists, dogged pushing of traditional rough sampling methods to their limits, and the invention and lateral prompt application of precise electronic timing and sensing devices to shipboard observation of deep ocean seafloor/crustal elements. SIO's multifaceted expeditions of those years were conceived, planned and often lead by graduate students making thesis observations, assisted by their fellows as "warm bodies," perhaps with more senior staff scientists making specific collections at key localities. Education was real-time: discovering--reflection--discussion, and mutual tutoring. The principal factor that made such operation scientifically and educationally successful was SIO's then Director, Roger Revelle, a benevolent and trusting, but very perceptive, godfather.

Paleoclimates: Understanding climate change past and present

USGS Publications Warehouse

Cronin, Thomas M.

2010-01-01

The field of paleoclimatology relies on physical, chemical, and biological proxies of past climate changes that have been preserved in natural archives such as glacial ice, tree rings, sediments, corals, and speleothems. Paleoclimate archives obtained through field investigations, ocean sediment coring expeditions, ice sheet coring programs, and other projects allow scientists to reconstruct climate change over much of earth's history. When combined with computer model simulations, paleoclimatic reconstructions are used to test hypotheses about the causes of climatic change, such as greenhouse gases, solar variability, earth's orbital variations, and hydrological, oceanic, and tectonic processes. This book is a comprehensive, state-of-the art synthesis of paleoclimate research covering all geological timescales, emphasizing topics that shed light on modern trends in the earth's climate. Thomas M. Cronin discusses recent discoveries about past periods of global warmth, changes in atmospheric greenhouse gas concentrations, abrupt climate and sea-level change, natural temperature variability, and other topics directly relevant to controversies over the causes and impacts of climate change. This text is geared toward advanced undergraduate and graduate students and researchers in geology, geography, biology, glaciology, oceanography, atmospheric sciences, and climate modeling, fields that contribute to paleoclimatology. This volume can also serve as a reference for those requiring a general background on natural climate variability.

SIOExplorer: Advances Across Disciplinary and Institutional Boundaries

NASA Astrophysics Data System (ADS)

Miller, S. P.; Clark, D.; Helly, J.; Sutton, D.; Houghton, T.

2004-12-01

Strategies for interoperability have been an underlying theme in the development of the SIOExplorer Digital Library. The project was launched three years ago to stabilize data from 700 cruises by the Scripps Institution of Oceanography (SIO), scattered across distributed laboratories and on various media, mostly off-line, including paper and at-risk magnetic tapes. The need for a comprehensive scalable approach to harvesting data from 40 years of evolving instrumentation, media and formats has resulted in the implementation of a digital library architecture that is ready for interoperability. Key metadata template files maintain the integrity of the metadata and data structures, allowing forward and backward compatibility throughout the project as metadata blocks evolve or data types are added. The overall growth of the library is managed by federating new collections in disciplines as needed, each with their own independent data publishing authority. We now have a total of four collections: SIO Cruises, SIO Photo Archives, the Seamount Catalog, and the new Educators' Collection for learning resources. The data types include high resolution meteorological observations, water profiles, biological and geological samples, gravity, magnetics, seafloor swath mapping sonar files, maps and visualization files. The library transactions across the Internet amount to approximately 50,000 hits and 6 GB of downloads each month. We are currently building a new Geological Collection with thousands of dredged rocks and cores, a Seismic Collection with 30 years of reflection data, and a Physical Oceanography Collection with 50 cruises of Hydrographic Doppler Sonar System (HDSS) deep acoustic current profiling data. For the user, a Java CruiseViewer provides an interactive portal to the all the federated collections. With CruiseViewer, contents can be discovered by keyword or geographic searches over a global map, metadata can be browsed, and objects can be displayed or scheduled for download. For computer applications, REST and SOAP web services are being implemented to allow computer-to-computer interoperability for applications to search and receive data across the Internet. Discussions are underway to extend this approach and establish a digital library at the Woods Hole Oceanographic Institution for cruise data as well as extensive submersible and ROV digital video and mapping data. These efforts have been supported by NSF NSDL, ITR and OCE awards.

Phylogeography of Ophioblennius: the role of ocean currents and geography in reef fish evolution.

PubMed

Muss, A; Robertson, D R; Stepien, C A; Wirtz, P; Bowen, B W

2001-03-01

Many tropical reef fishes are divided into Atlantic and East Pacific taxa, placing similar species in two very different biogeographic regimes. The tropical Atlantic is a closed ocean basin with relatively stable currents, whereas the East Pacific is an open basin with unstable oceanic circulation. To assess how evolutionary processes are influenced by these differences in oceanography and geography, we analyze a 630-bp region of mitochondrial cytochrome b from 171 individuals in the blenniid genus Ophioblennius. Our results demonstrate deep genetic structuring in the Atlantic species, O. atlanticus, corresponding to recognized biogeographic provinces, with divergences of d = 5.2-12.7% among the Caribbean, Brazilian, St. Helena/Ascension Island, Gulf of Guinea, and Azores/Cape Verde regions. The Atlantic phylogeny is consistent with Pliocene dispersal from the western to eastern Atlantic, and the depth of these separations (along with prior morphological comparisons) may indicate previously unrecognized species. The eastern Pacific species, O. steindachneri, is characterized by markedly less structure than O. atlanticus, with shallow mitochondrial DNA lineages (dmax = 2.7%) and haplotype frequency shifts between locations in the Sea of Cortez, Pacific Panama, Clipperton Island, and the Galapagos Islands. No concordance between genetic structure and biogeographic provinces was found for O. steincdachneri. We attribute the phylogeographic pattern in O. atlanticus to dispersal during the reorganization of Atlantic circulation patterns that accompanied the shoaling of the Isthmus of Panama. The low degree of structure in the eastern Pacific is probably due to unstable circulation and linkage to the larger Pacific Ocean basin. The contrast in genetic signatures between Atlantic and eastern Pacific blennies demonstrates how differences in geology and oceanography have influenced evolutionary radiations within each region.

Understanding the Geological Structures of North China By Analyzing Regional Gravity and Magnetic Data

NASA Astrophysics Data System (ADS)

Shi, L.; Guo, L.; Meng, X.; Yao, C.

2010-12-01

North China is one of the most tectonically important regions in the world to study important continent geodynamics issues such as intraplate earthquakes, volcanism and continent-continent collision. The North China Craton, covering most of North China, bounded by complicated fault systems and orogenic belts, is one of the oldest cratons on the Earth, and is unique in its tectonic reactivation in the Late Mesozoic and Cenozoic. In the past few decades, a variety of geophysical methods were conducted to study geological tectonics and evolution of North China. We analyzed the regional gravity and magnetic data of this region using new data enhancement techniques to understand the regional geological structures. The satellite-derived free-air gravity anomalies with a resolution of 1 arc-minute were assembled from the Scripps Institution of Oceanography, and were then reduced to obtain Complete Bouguer Gravity Anomalies (CBGA). The Magnetic Anomalies (MA) with a resolution of 2 arc-minutes were assembled from the World Digital Magnetic Anomaly Map. The CBGA and the MA were then gridded on a regular grid, the MA were subsequently reduced to the magnetic pole. Then the data were processed with standard techniques to attenuate the high-frequency noise and analyze the regional and residual anomalies. Specially, we calculated the tilt-angle derivatives of the data. We then calculated the directional horizontal derivatives of the tilt-angle derivatives along different directions. This special processing derived clearer geological structures with more details. From the results of the preliminary processing, we analyzed the main deep faults and tectonic units distributed in this region. In the future, the interpretation of the CBGA and the MA with constraints of other geophysical methods will be performed for better understanding the deep structure of this region.

Integrated geophysical study of the northeastern margin of Tibetan Plateau

NASA Astrophysics Data System (ADS)

Shi, L.; Meng, X.; Guo, L.

2011-12-01

Tibetan Plateau, the so-called "Roof of the World", is a direct consequence of collision of the Indian plate with the Eurasian plate starting in the early Cenozoic time. The continent-continent collision is still going on. The northeastern margin of Tibetan Plateau is the front part of the Tibetan Plateau extends to mainland and favorable area for studying uplift and deformation of the Tibetan Plateau. In the past decades, a variety of geophysical methods were conducted to study geodynamics and geological tectonics of this region. We assembled satellite-derived free-air gravity anomalies with a resolution of one arc-minute from the Scripps Institution of Oceanography, and reduced them to obtain Complete Bouguer Gravity Anomalies. Then we gridded Complete Bouguer Gravity Anomalies on a regular grid, and subsequently processed them with the preferential continuation method to attenuate high-frequency noise and analyzed regional and residual anomalies. We also calculated tilt-angle derivative of Complete Bouguer Gravity Anomalies to derive clearer geological structures with more details. Then we calculated the depth distribution of the Moho discontinuity surface in this area by 3D density interface inversion. From the results of preliminary processing, we analyzed the main deep faults and geological tectonics in this region. We extracted seven important profiles' data of Complete Bouguer Gravity Anomalies in this area, and then did forward modeling and inversion on each profile with constraints of geological information and other geophysical data. In the future, we will perform 3D constrained inversion of Complete Bouguer Gravity Anomalies in this region for better understanding deep structure and tectonics of the northeastern margin of Tibetan Plateau.

Shuttle imaging radar-C science plan

NASA Technical Reports Server (NTRS)

1986-01-01

The Shuttle Imaging Radar-C (SIR-C) mission will yield new and advanced scientific studies of the Earth. SIR-C will be the first instrument to simultaneously acquire images at L-band and C-band with HH, VV, HV, or VH polarizations, as well as images of the phase difference between HH and VV polarizations. These data will be digitally encoded and recorded using onboard high-density digital tape recorders and will later be digitally processed into images using the JPL Advanced Digital SAR Processor. SIR-C geologic studies include cold-region geomorphology, fluvial geomorphology, rock weathering and erosional processes, tectonics and geologic boundaries, geobotany, and radar stereogrammetry. Hydrology investigations cover arid, humid, wetland, snow-covered, and high-latitude regions. Additionally, SIR-C will provide the data to identify and map vegetation types, interpret landscape patterns and processes, assess the biophysical properties of plant canopies, and determine the degree of radar penetration of plant canopies. In oceanography, SIR-C will provide the information necessary to: forecast ocean directional wave spectra; better understand internal wave-current interactions; study the relationship of ocean-bottom features to surface expressions and the correlation of wind signatures to radar backscatter; and detect current-system boundaries, oceanic fronts, and mesoscale eddies. And, as the first spaceborne SAR with multi-frequency, multipolarization imaging capabilities, whole new areas of glaciology will be opened for study when SIR-C is flown in a polar orbit.

From marine ecology to biological oceanography

NASA Astrophysics Data System (ADS)

Mills, Eric L.

1995-03-01

Looking back from the 1990s it seems natural to view the work done in the Biologische Anstalt Helgoland by Friedrich Heincke and his colleagues, beginning in 1892, as marine ecology or marine biology, and that done in Kiel, under Victor Hensen and Karl Brandt, as biological oceanography. But historical analysis shows this view to be untenable. Biological oceanography, as a research category and a profession, does not appear until at least the 1950's. In the German tradition of marine research, “Ozeanographie”, originating in 19th century physical geography, did not include the biological sciences. The categories “Meereskunde” and “Meeresforschung” covered all aspects of marine research in Germany from the 1890's to the present day. “Meeresbiologie” like that of Brandt, Heincke, and other German marine scientists, fitted comfortably into these. But in North America no such satisfactory professional or definitional structure existed before the late 1950's. G. A. Riley, one of the first biological oceanographers, fought against descriptive, nonquantitative American ecology. In 1951 he described biological oceanography as the “ecology of marine populations”, linking it with quantitative population ecology in the U.S.A. By the end of the 1960's the U.S. National Science Foundation had recognized biological oceanography as a research area supported separately from marine biology. There was no need for the category “biological oceanography” in German marine science because its subject matter lay under the umbrella of “Meereskunde” or “Meeresforschung”. But in North America, biological oceanography — a fundamental fusion of physics and chemistry with marine biology — was created to give this marine science a status higher than that of the conceptually overloaded ecological sciences. The sociologists Durkheim and Mauss claimed in 1903 that, “the classification of things reproduces the classification of men”; similarly, in science, the classification of professions reproduces the status that their practitioners hope to achieve.

An Earth Summit in a Large General Education Oceanography Class

NASA Astrophysics Data System (ADS)

Dodson, H.; Prothero, W. A.

2001-12-01

An Earth Summit approach in UCSB's undergraduate physical oceanography course has raised student interest level while it also supports the course goals of increased learner awareness of the process of science, and critical analysis of scientific claims. At the beginning of the quarter, each group of students chooses a country to represent in the Earth Summit. During the course of the quarter, these groups relate each of the class themes to their chosen country. Themes include 1) ocean basins and plate tectonics, 2) atmospheres, oceans and climate, and 3) fisheries. Students acquire and utilize Earth data to support their positions. Earth data sources include the "Our Dynamic Planet" CDROM (http://oceanography.geol.ucsb.edu/ODP_Advert/odp_onepage.htm), NOAA's ocean and climate database (http://ferret.wrc.noaa.gov/las/), WorldWatcher CD (http://www.worldwatcher.northwestern.edu/) and JPL's Seawinds web site (http://haifung.jpl.nasa.gov/index.html). During the atmospheres, oceans and climate theme, students choose from 12 mini-studies that use various kinds of on-line Earth data related to important global or regional phenomena relevant to the course. The Earth datasets that the students access for their analysis include: winds; atmospheric pressure; ocean chemistry; sea surface temperature; solar radiation; precipitation, etc. The first group of 6 mini-studies focus on atmosphere and ocean, and are: 1) global winds and surface currents, 2) atmosphere and ocean interactions, 3) stratospheric ozone depletion, 4) El Nino, 5) Indian monsoon, and 6) deep ocean circulation. The second group focus on the Earth's heat budget and climate and are: 1) influence of man's activities on the climate, 2) the greenhouse effect, 3) seasonal variation and the Earth's heat budget, 4) global warming, 5) paleoclimate, and 6) volcanoes and climate. The students use what they have learned in these mini-studies to address atmospheric and climatic issues pertinent to their specific Earth Summit countries. For example, students representing the country of Chile might model their investigations after a)winds and surface currents, b)atmosphere and ocean interactions, c) stratospheric ozone depletion, d)El Nino; and/or e)volcanoes and climate. Please join the "Oceanography" interest group of DLESE to discuss, develop, and access oceanography related mini-studies that use earth data (http://oceanography.geol.ucsb.edu/dlese/wg_oceanog/Index.html). >http://oceanography.geol.ucsb.edu/AWP/Class_Info/GS-4/Labs/Labs Index.html

From satellite altimetry to operational oceanography and Argo: three revolutions in oceanography (Fridtjof Nansen Medal Lecture)

NASA Astrophysics Data System (ADS)

Le Traon, P. Y.

2012-04-01

The launch of the US/French mission Topex/Poseidon (T/P) (CNES/NASA) in August 1992 was the start of a revolution in oceanography. For the first time, a very precise altimeter system optimized for large scale sea level and ocean circulation observations was flying. Topex/Poseidon revolutionized our vision and understanding of the ocean. It provided new views of the large scale seasonal and interannual sea level and ocean circulation variations. T/P alone could not observe the mesoscale circulation. In the 1990s, the ESA satellites ERS-1/2 were flying simultaneously with T/P. The ERS-1/2 orbit was well adapted for mesoscale circulation sampling but the orbit determination and altimeter performance were much less precise than for T/P. We demonstrated that we could use T/P as a reference mission for ERS-1/2 and bring the ERS-1/2 data to an accuracy level comparable to T/P. This was an essential first step for the merging of T/P and ERS-1/2. The second step required the development of a global optimal interpolation method. Near real time high resolution global sea level anomaly maps were then derived. These maps have been operationally produced as part of the SSALTO/DUACS system for the last 15 years. They are now widely used by the oceanographic community and have contributed to a much better understanding and recognition of the role and importance of mesoscale dynamics. The unique capability of satellite altimetry to observe the global ocean in near real time at high resolution was essential to the development of global ocean forecasting, a second revolution in oceanography. The Global Ocean Data Assimilation Experiment (GODAE) (1998-2008) was phased with the T/P and ERS-1/2 successors (Jason-1 and ENVISAT) and was instrumental in the development of global operational oceanography capabilities. Europe played a leading role in GODAE. In 1998, the global in-situ observing system was inadequate for the global scope of GODAE. This led to the development of Argo, an initial joint venture between CLIVAR and GODAE. Argo has been an outstanding success. The 3000 Argo profiling floats now provide the most important global in-situ observations to monitor and understand the role of the ocean on the earth climate. This is a third revolution in oceanography. I was lucky enough to be involved with many colleagues and friends in these three revolutions or breakthroughs in oceanography. The presentation will provide some historical background on the development of the SSALTO/DUACS merged altimeter products and an overview of their utility and use for ocean research and operational oceanography. I will thengo throughthe development of operational oceanography and Argo over the past 15 years focussing on European contributions, in particular, in the framework of the GMES Marine Service, EuroGOOSand the Euro-Argo research infrastructure. Perspectives and new challenges for the integrated global ocean observing system will be finally discussed.

OGS Explora is back to Antarctica for three projects focused on the Ross Sea eastern continental slope: EU/FP7-EUROFLEETS (http://www.eurofleets.eu) ANTSSS, PNRA (Programma Nazionale Di Ricerche in Antartide) ODYSSEA, and PNRA WHISPERS. These projects employ three main methods: 1) geophysics (multichannel seismic reflection, sub-bottom and multibeam morphobathymetric survey); 2) geology (gravity corer and box-corer); oceanography (CTD, LADCP, turbulence). The general objective is to contribute to the understanding of past and present ocean dynamics and glacial history of this Antarctic sector. In particular, to find evidence (in the geometry and distribution of the stratigraphic sequences) of Miocene-Pleistocene West Antarctic Ice Sheet and East Antarctic Ice Sheet advances and retreats and of their effects on Ross Sea Bottom Water formation and dynamics. The gravity cores provide the chronological control for the Quaternary. Deep sea drilling (through IODP Exp. 374, whose additional alternative sites are surveyed during this cruise) will provide the chronological control for the pre-Quaternary seismic sequences.

The use of bathymetric data in society and science: a review from the Baltic Sea.

PubMed

Hell, Benjamin; Broman, Barry; Jakobsson, Lars; Jakobsson, Martin; Magnusson, Ake; Wiberg, Patrik

2012-03-01

Bathymetry, the underwater topography, is a fundamental property of oceans, seas, and lakes. As such it is important for a wide range of applications, like physical oceanography, marine geology, geophysics and biology or the administration of marine resources. The exact requirements users may have regarding bathymetric data are, however, unclear. Here, the results of a questionnaire survey and a literature review are presented, concerning the use of Baltic Sea bathymetric data in research and for societal needs. It is demonstrated that there is a great need for detailed bathymetric data. Despite the abundance of high-quality bathymetric data that are produced for safety of navigation purposes, the digital bathymetric models publicly available to date cannot satisfy this need. Our study shows that DBMs based on data collected for safety of navigation could substantially improve the base data for administrative decision making as well as the possibilities for marine research in the Baltic Sea.

Charney's Influence on Modern Oceanography

NASA Astrophysics Data System (ADS)

Cane, M. A.

2017-12-01

In this talk I will review some of Jule Charney's impacts on current oceanographic research. He was of course a major seminal figure in geophysical fluid dynamics, an approach to understanding the atmosphere and oceans that has been thoroughly absorbed in contemporary thinking. In oceanography, his publications make vorticity dynamics the centerpiece of his analysis. Here I pursue two other aspects of his work. The first is to note that his 1955 paper "The Gulf Stream as an inertial boundary layer" appears to be the earliest numerical model in oceanography. The second is that his work on the equatorial undercurrent leads to a simplification of equatorial ocean structure that was exploited by Zebiak and Cane in their model for ENSO, and thus structures later views of how equatorial ocean dynamics influence sea surface temperature.

DeVito, M. Catherine

AGU Fellow Roger R.D. Revelle, past Oceanography section president and recipient of the William Bowie Medal, died July 15. Revelle was a pioneer in global warming research and plate tectonics, and a major contributor to oceanography, education, and public policy.Appointed an AGU Fellow in 1936, Revelle was president of the Oceanography section from 1953-1956. In 1968 he was awarded the Bowie Medal, AGU's highest honor. Revelle extended his activities beyond the limits of his specialty to actively work with scientists in other fields for the betterment of science. In presenting the award, George E. Backus described Revelle's career as one of bold and selfless service to science and his fellow man. “If scientific progress is built on the shoulders of giants, Roger Revelle is certainly to be counted among the giants.”

Extracting physical parameters from marine seismic data: New methods in seismic oceanography and velocity inversion

NASA Astrophysics Data System (ADS)

Fortin, Will F. J.

The utility and meaning of a geophysical dataset is dependent on good interpretation informed by high-quality data, processing, and attribute examination via technical methodologies. Active source marine seismic reflection data contains a great deal of information in the location, phase, and amplitude of both pre- and post-stack seismic reflections. Using pre- and post-stack data, this work has extracted useful information from marine reflection seismic data in novel ways in both the oceanic water column and the sub-seafloor geology. In chapter 1 we develop a new method for estimating oceanic turbulence from a seismic image. This method is tested on synthetic seismic data to show the method's ability to accurately recover both distribution and levels of turbulent diffusivity. Then we apply the method to real data offshore Costa Rica where we observe lee waves. Our results find elevated diffusivities near the seafloor as well as above the lee waves five times greater than surrounding waters and 50 times greater than open ocean diffusivities. Chapter 2 investigates subsurface geology in the Cascadia Subduction Zone and outlines a workflow for using pre-stack waveform inversion to produce highly detailed velocity models and seismic images. Using a newly developed inversion code, we achieve better imaging results as compared to the product of a standard, user-intensive method for building a velocity model. Our results image the subduction interface ~30 km farther landward than previous work and better images faults and sedimentary structures above the oceanic plate as well as in the accretionary prism. The resultant velocity model is highly detailed, inverted every 6.25 m with ~20 m vertical resolution, and will be used to examine the role of fluids in the subduction system. These results help us to better understand the natural hazards risks associated with the Cascadia Subduction Zone. Chapter 3 returns to seismic oceanography and examines the dynamics of nonlinear internal wave pulses in the South China Sea. Coupling observations from the seismic images with turbulent patterns, we find no evidence for hydraulic jumps in the Luzon passage. Our data suggests geometric resonance may be the underlying physics behind large amplitude nonlinear internal wave pulses seen in the region. We find increased levels of turbulent diffusivity in deep water below 1000 m, associated with internal tide pulses, and near the steep slopes of both the Heng-Chun and Lan-Yu ridges.

The Second International Indian Ocean Expedition (IIOE-2)

The International Indian Ocean Expedition (IIOE) was one of the greatest international, interdisciplinary oceanographic research efforts of all time. Planning for the IIOE began in 1959 and the project officially continued through 1965, with forty-six research vessels participating under fourteen different flags. The IIOE motivated an unprecedented number of hydrographic surveys (and repeat surveys) over the course of the expedition covering the entire Indian Ocean basin. And it was an interdisciplinary endeavor that embraced physical oceanography, chemical oceanography, meteorology, marine biology, marine geology and geophysics. The end of 2015 will mark the 50th Anniversary of the completion of the IIOE. SCOR and the IOC are working to stimulate a new phase of coordinated international research focused on the Indian Ocean for a 5-year period beginning in late 2015 and continuing through 2020. The goal is to help to organize ongoing research and stimulate new initiatives in the 2015-2020 time frame as part of a larger expedition. Several International programs that have research ongoing or planned in the Indian Ocean during this time period and many countries are planning cruises in this time frame as well. These programs and national cruises will serve as a core for the new Indian Ocean research focus, which has been dubbed "IIOE-2." The overarching goal of the IIOE-2 is to advance our understanding of interactions between geological, oceanic and atmospheric processes that give rise to the complex physical dynamics of the Indian Ocean region, and to determine how those dynamics affect climate, extreme events, marine biogeochemical cycles, ecosystems and human populations. This understanding is required to predict the impacts of climate change, pollution, and increased fish harvesting on the Indian Ocean and its nations, as well as the influence of the Indian Ocean on other components of the Earth System. New understanding is also fundamental to policy makers for the development of sustainable coastal zone, ecosystem, and fisheries management strategies for the Indian Ocean. Other goals of IIOE-2 include helping to build research capacity and improving availability and accessibility of oceanographic data from the region. The IIOE-2 Science Plan is structured around six scientific themes. Each theme comprises a set of core questions fundamental to our need to understand the forcings, processes, and resultant variability of the Indian Ocean and to develop the capacity to predict how this variability will impact human populations in the future. In this presentation we will report on current efforts to motivate an IIOE-2 and we will present the draft science plan that has been commissioned by SCOR.

2008-12-01

The Center for Microbial Oceanography: Research and Education (C-MORE) is a multi-institution Science and Technology Center, established by the National Science Foundation in 2006. C-MORE's research mission is to facilitate a more comprehensive understanding of the diverse assemblages of microorganisms in the sea, ranging from the genetic basis of marine microbial biogeochemistry including the metabolic regulation and environmental controls of gene expression, to the processes that underpin the fluxes of carbon, related bioelements, and energy in the marine environment. The C-MORE education and outreach program is focused on increasing scientific literacy in microbial oceanography among students, educators, and the general public. A first step toward this goal is defining the key concepts that constitute microbial oceanography. After lengthy discussions with scientists and educators, both within and outside C-MORE, we have arrived at six key concepts: 1) Marine microbes are very small and have been around for a long time; 2) Life on Earth could not exist without microbes; 3) Most marine microbes are beneficial; 4) Microbes are everywhere: they are extremely abundant and diverse; 5) Microbes significantly impact our global climate; and 6) There are new discoveries every day in the field of microbial oceanography. A C-MORE-produced brochure on these six key concepts will be distributed at the meeting. Advanced copies may be requested by email or downloaded from the C-MORE web site(http://cmore.soest.hawaii.edu/downloads/MO_key_concepts_hi-res.pdf). This brochure also includes information on career pathways in microbial oceanography, with the aim of broadening participation in the field. C-MORE is eager to work in partnership to incorporate these key concepts into other science literacy publications, particularly those involving ocean and climate literacy. We thank the following contributors and reviewers: P Chisholm, A Dolberry, and A Thompson (MIT); N Lawrence (Santa Cruz Boardwalk); R Foster, S Mansergh and P Moisander (UC Santa Cruz); A Culley, K Doggett, J Edmonds, A Eiler, A Fong, D Hayakawa, D Karl, P Kemp, B Li, N Puniwai, B Wai, and S Wilson (U Hawaii); J Becker and M Nieto-Cid (WHOI); M McCaffrey (CIRES).

A community engagement project in an undergraduate oceanography course to increase engagement and representation in marine science among high school students

NASA Astrophysics Data System (ADS)

Clark, C. D.; Prairie, J. C.; Walters, S. A.

2016-02-01

In the context of undergraduate education in oceanography, we are constantly striving for innovative ways to enhance student learning and enthusiasm for marine science. Community engagement is a form of experiential education that not only promotes a better understanding of concepts among undergraduate students but also allows them to interact with the community in a way that is mutually beneficial to both parties. Here I present on my experience in incorporating a community engagement project in my undergraduate physical oceanography course at the University of San Diego (USD) in collaboration with Mission Bay High School (MBHS), a local Title 1 International Baccalaureate high school with a high proportion of low-income students and students from underrepresented groups in STEM. As part of this project, the undergraduate students from my physical oceanography course were challenged to develop interactive workshops to present to the high school students at MBHS on some topic in oceanography. Prior to the workshops, the USD students met with the high school students at MBHS during an introductory meeting in which they could learn about each other's interests and backgrounds. The USD students then worked in teams of three to design a workshop proposal in which they outlined their plan for a workshop that was interactive and engaging, relying on demonstrations and activities rather than lecture. Each of the three teams then presented their workshops on separate days in the Mission Bay High School classroom. Finally, the USD students met again with the high school students at MBHS for a conclusion day in which both sets of students could discuss their experiences with the community engagement project. Through the workshop itself and a reflection essay written afterwards, the USD students learned to approach concepts in oceanography from a different perspective, and think about how student backgrounds can inform teaching these concepts. I will describe preliminary outcomes of this project and discuss the potential of community engagement projects in general to positively impact and integrate both undergraduate and high school education in ocean science.

The Effective and Evolving Role of Graduate Students in the SURFO REU Program

NASA Astrophysics Data System (ADS)

Pockalny, R. A.

2005-12-01

The Summer Undergraduate Research Fellowships in Oceanography (SURFO) program is a 10-week research/educational program designed to expose 9 undergraduates per year to cutting-edge, authentic oceanographic research at the Graduate School of Oceanography/University of Rhode Island. The SURFO program primarily focuses on the more quantitative aspects of oceanography (e.g., physical oceanography, geophysical fluid dynamics and marine geophysics), which closely parallel the strengths of GSO/URI. Thus, the primary undergraduate population targeted by the program includes students from various disciplines, but with strong backgrounds in math, physics, computer science, and engineering. Over its 20-year existence, the SURFO program has continuously evolved; however, three basics goals of the program have been maintained: 1) expose students to the breadth and depth of oceanography, 2) provide students with an authentic research experience, and 3) integrate/assimilate students into the lifestyle and community of a graduate research institution. An integral component for achieving these goals has been the inclusion of graduate students as workshop leaders/instructors, research mentors, and social directors. In these roles the graduate students act as a 'big brother/sister' to transition the undergraduates into the academic and research community. The graduate students also initially behave as liaisons between the senior researcher and the SURFO participant by fielding questions and concerns the undergraduate may be too intimidated to voice. As the summer progresses, the graduate students typically evolve into a lead research advisor and begin to learn effective techniques for advising students. Responses from SURFO participants on exit questionnaires frequently comment on how their experience and research project were directly affected by the extent of graduate student participation during the summer. Anecdotal evidence also indicates the participating graduate students gain maturity in their approach to research and become more willing advisees.

Remote sensing for oceanography: Past, present, future

NASA Technical Reports Server (NTRS)

Mcgoldrick, L. F.

1984-01-01

Oceanic dynamics was traditionally investigated by sampling from instruments in situ, yielding quantitative measurements that are intermittent in both space and time; the ocean is undersampled. The need to obtain proper sampling of the averaged quantities treated in analytical and numerical models is at present the most significant limitation on advances in physical oceanography. Within the past decade, many electromagnetic techniques for the study of the Earth and planets were applied to the study of the ocean. Now satellites promise nearly total coverage of the world's oceans using only a few days to a few weeks of observations. Both a review of the early and present techniques applied to satellite oceanography and a description of some future systems to be launched into orbit during the remainder of this century are presented. Both scientific and technologic capabilities are discussed.

Gender Diversity in the Geosciences: Current Status and Future Trends

Since 1995, the proportion of women in the American Geological Institute's Directory of Geoscience Departments has risen from 12% of the entries to 14.2% (exclusive of administrative assistants). Separated into type of institution, there is a greater proportion of women at Museums (17.5%), Bachelor's-granting institutions (17.2%), and non degree-granting academic institutions (16.5%), but these percentages drop when marginal positions, such as "Lecturer", "Instructor", "Adjunct" and "Cooperating Faculty" are excluded to 14.0% (Museums), 15.9% (B.S.-granting institution). The institutions with the lowest proportion of females are the State Geologic Surveys (12.6% female), followed by Ph.D.-granting institutions (12.8% female). Fifteen Ph.D.-granting institutions in the United States still have no females on their faculty. These numbers contrast poorly with the proportion of women receiving B.S. or M.S. degrees in the geosciences over the last 10 years (34 B.S.%/30% M.S. in 1996) and with the proportion receiving the PhD. (24% over the last 10 years; 30% in 2000). There is a significant loss of women between the M.S. and Ph.D. degrees, and between the Ph.D. degree and a tenure-track position. Women reach or exceed their overall average in four subdisciplines of the geosciences: paleontology, geochemistry, general geology, and oceanography. Women are most under-represented in engineering geology, followed by economic geology, planetology, soil science, geophysics, and hydrology. Within these subdisciplines, women exceed their overall average in geomagnetism and paleomagnetism, ground water and surface water studies, soil biochemistry, and meteorite study. Most women in tenure-track positions at degree-granting institutions are currently Assistant Professors while most men are Full Professors. The proportion of women hired into Assistant Professor positions has increased over the last five years, from 22% hired 5 to 10 years ago to 25% hired 1 to 5 years ago. These data indicate that women are beginning to approach being hired at the same proportion in which they receive PhD degrees in the geosciences. Despite common myth, women are not getting "all" of the new Assistant Professor positions; they remain under-represented at every academic rank, at every type of institution. At the current rate of increase, we expect women will not achieve parity in the geosciences for another 40 years.

Environmental drivers of epibenthic megafauna on a deep temperate continental shelf: A multiscale approach

NASA Astrophysics Data System (ADS)

Lacharité, Myriam; Metaxas, Anna

2018-03-01

Evaluating the role of abiotic factors in influencing the distribution of deep-water (>75-100 m depth) epibenthic megafaunal communities at mid-to-high latitudes is needed to estimate effects of environmental change, and support marine spatial planning since these factors can be effectively mapped. Given the disparity in scales at which these factors operate, incorporating multiple spatial and temporal scales is necessary. In this study, we determined the relative importance of 3 groups of environmental drivers at different scales (sediment, geomorphology, and oceanography) on epibenthic megafauna on a deep temperate continental shelf in the eastern Gulf of Maine (northwest Atlantic). Twenty benthic photographic transects (range: 611-1021 m; total length surveyed: 18,902 m; 996 images; average of 50 ± 16 images per transect) were performed in July and August 2009 to assess the abundance, composition and diversity of these communities. Surficial geology was assessed using seafloor imagery processed with a novel approach based on computer vision. A bathymetric terrain model (horizontal resolution: 100 m) was used to derive bathymetric variability in the vicinity of transects (1.5, 5 km). Oceanography at the seafloor (temperature, salinity, current speed, current direction) over 10 years (1999-2008) was determined using empirical (World Ocean Database 2013) and modelled data (Finite-Volume Community Ocean Model; 45 vertical layers; horizontal resolution: 1.7-9.5 km). The relative influence of environmental drivers differed between community traits. Abundance was enhanced primarily by swift current speeds, while higher diversity was observed in coarser and more heterogeneous substrates. In both cases, the role of geomorphological features was secondary to these drivers. Environmental variables were poor predictors of change in community composition at the scale of the eastern Gulf of Maine. This study demonstrated the need for explicitly incorporating scales into habitat modelling studies in these regions, and targeting specific drivers for community traits of interest.

Retrospective

NASA Astrophysics Data System (ADS)

Brooks, David A.

Charting a course toward an uncertain future is always a risky business, especially among shoals of fiscal restraint or national tragedy, and the prudent navigator is well advised to remember where he's been as he looks ahead. The ocean and space sciences are poised for grand joint adventures, but shrinking budgets and the lingering Challenger numbness are restrictive lee shores that must be considered when laying plans. To sharpen the focus on future choices, it may be helpful to glance in the geophysical rearview mirror and remember some of the challenges and opportunities of a different era.A quarter century is a long time, but many images from 25 years ago can still be recalled in crisp detail, like photographs in a scrapbook. In 1961, results from the International Geophysical Year (IGY) filled the pages of the Transactions of the American Geophysical Union, and the U.S. program of space exploration finally was underway with conviction. The Indian Ocean Expedition, conceived during the IGY, ushered in a new era of international oceanography. The TIROS III satellite beamed to earth fuzzy pictures of tropical storms and revealed the intricate writhings of the Gulf Stream. Forecasters and fluid dynamicists suddenly saw new horizons, and geophysical turbulence became a major topic at the IUGG Symposium in Marseilles, France. Papers with prescient themes were presented at the AGU Ocean Section meeting: June Pattullo (then at Oregon State College, Corvallis) on heat storage in the Pacific; Ferris Webster (then at Woods Hole Oceanographic Institution, Woods Hole, Mass.) on Gulf Stream meanders. Polar oceanography was well represented in AGU journals: Kenneth Hunkins (at what was then called the Lamont Geological Observatory, Palisades, N.Y.) described the Alpha Rise, discovered from a drifting Arctic ice island, and Edward Thiel (then at the University of Minnesota, Minneapolis) and his co-workers discussed open ocean tides, gravimetrically measured from Antarctic ice shelves.

During World War II the Scripps Institution of Oceanography (SIO) became involved in the oceanographic training of officers. This, combined with a rekindling of interest in the Pacific Ocean during and after the war, catapulted SIO in the late 1940s to a position of prominence in oceanographic education. The leader of the institution, both administratively and academically, was Harald Sverdrup (Figure 1). When he became director in 1936, only five graduate students were enrolled.

Effectiveness of a mining simulation cooperative learning activity on the cognitive and affective achievement of students in a lower division physical geology course: A confluent approach

NASA Astrophysics Data System (ADS)

Tolhurst, Jeffrey Wayne

Most students enrolled in lower division physical geology courses are non-majors and tend to finish the course with little appreciation of what it is geologists really do. They may also be expected to analyze, synthesize, and apply knowledge from previous laboratory experiences with little or no instruction and/or practice in utilizing the critical thinking skills necessary to do so. This study sought to answer two research questions: (1) do physical geology students enrolled in a course designed around a mining simulation activity perform better cognitively than students who are taught the same curriculum in the traditional fashion; and (2) do students enrolled in the course gain a greater appreciation of physical geology and the work that geologists do. Eighty students enrolled in the course at Columbia College, Sonora, California over a two year period. During the first year, thirty-one students were taught the traditional physical geology curriculum. During the second year, forty-nine students were taught the traditional curriculum up until week nine, then they were taught a cooperative learning mining simulation activity for three weeks. A static group, split plot, repeated measures design was used. Pre- and post-tests were administered to students in both the control and treatment groups. The cognitive assessment instrument was validated by content area experts in the University of South Carolina Geological Sciences Department. Students were given raw lithologic, gravimetric, topographic, and environmental data with which to construct maps and perform an overlay analysis. They were tested on the cognitive reasoning and spatial analysis they used to make decisions about where to test drill for valuable metallic ores. The affective instrument used a six point Likert scale to assess students' perceived enjoyment, interest, and importance of the material. Gains scores analysis of cognitive achievement data showed a mean of 2.43 for the control group and 4.47 for the treatment group, statistically significantly different at the alpha = 0.05 level (p = 0.0038). Gains scores for the affective data indicated no statistically significant differences between the treatment and control groups. The simulation seems to make a difference in terms of students' intellectual performance, but not in terms of their attitudinal perceptions of the course. Results support the hypothesis that cognitive achievement is improved by a cooperative learning mining simulation activity. One implication might include adapting and implementing the model in lower division physical geology courses. Another would be to develop similar activities for other lower division, non-majors earth science courses (i.e. environmental geology, astronomy, meteorology, oceanography, etc.) that could improve students' subject matter knowledge. Additionally, the research supports shifting the locus of control from the instructor to students as well as the use of the principles of active learning, cooperative learning, and confluent education in the science classroom.

Taking "The Math You Need When You Need It" Modules Beyond Introductory Geology Courses

NASA Astrophysics Data System (ADS)

Baer, E. M.; Wenner, J. M.; Burn, H. E.

2012-12-01

"The Math You Need, When You Need It" (TMYN) modules are finding use well beyond the courses for which they were originally written. However, faculty survey responses indicate that the modules are used in similar ways, suggesting that the overall design of the modules is effective. TMYN modules are online resources designed to help students develop quantitative skills in conjunction with introductory geology courses. Since 2010, 29 faculty members at 26 institutions used these asynchronous resources at in 68 different courses nationwide, impacting about 3000 students. After each use of the modules, instructors responded to a survey about their use of the modules and the impact on each course and student cohort. Of the 29 instructors, 16 responded with a total of 36 implementations, a 52% response rate. Survey responses indicate use of TMYN modules in classes well beyond their original design. The modules were originally designed for students in introductory geology classes, especially those targeted at non-geoscience majors. Sixty-nine percent (22/32) of TMYN courses included introductory geology courses such as Physical Geology, Earth System Science and Environmental Geology. The remainder of courses included multiple uses in oceanography and meteorology courses and more specialized geoscience courses such as geomorphology, structural geology and hydrology. Surveys suggest that only 63% of courses that used TMYN (20/32) were targeted to students in general education courses. Nine percent (3/32) of courses were targeted to STEM majors and 19% (6/32) were specifically targeted to geoscience majors, including upper-level courses. Despite the wide variety of institutions, instructors, classes, and student educational goals, faculty incorporated the modules into their curriculum in as originally designed, indicating that the overall design of the modules is effective. Twenty-two respondents indicate that modules were assigned immediately prior to using a skill in the classroom (either in lab exercises or a lecture period). Almost all instructors employed pre- and posttests to gauge learning. More than ¾ of survey respondents introduced the modules within the first week of class. In all but one instance, students were instructed to complete an online quiz immediately after working through the online modules and most (77%) designed these post-module quizzes as formative assessments allowing at least 3 attempts. The grades on these modules contributed to students' grades but were relatively low stakes with 88% reporting that the modules contributed to less than 10% of a student's course grade. Given the use beyond the introductory geology classroom and the similarity of the use of these modules in a wide variety of courses, it appears that the design of the modules is sound. However, previous studies have indicated that mathematical skills are not easily transferred (e.g. Bassok. and Holyoak, 1989) suggesting the adaptation of the modules for use outside the geosciences.

Integrated Earth Data Applications (IEDA) is a community-based facility that serves to support, sustain, and advance the geosciences by providing data services for observational geoscience data from the Ocean, Earth, and Polar Sciences. Many dedicated systems such as the Petrological Database (PetDB), Marine Geoscience Data System (MGDS), System for Earth Sample Registration (SESAR), Data Coordination Center for the U.S. Antarctic Program (USAP-DCC), etc., under the umbrella of the IEDA framework, were developed to support the preservation, discovery, retrieval, and analysis of a wide range of observational field and analytical data types from diverse communities. However, it is currently difficult to maintain consistency of indexing content within IEDA schema, and perform unified or precise searching of the data in these diverse systems as each system maintains separate vocabularies, hierarchies, authority files, or sub taxonomies. We present here the IEDA Thesaurus, a system, which combines existing separate controlled vocabularies from the different systems under the IEDA schema into a single master controlled vocabulary, also introducing some new top facets for future long-term use. The IEDA thesaurus contains structured terminology for petrology, geochemistry, sedimentology, oceanography, geochronology, and volcanology, and other general metadata fields. 18 top facets (also called 'top categories') are defined, including equipment, geographic gazetteer, geologic ages, geologic units, materials, etc. The terms of the thesaurus are cross validated with others popular geoscience vocabularies such as GeoRef Thesaurus, U.S. Geological Survey Library Classification System, Global Change Master Directory (GCMD), and Semantic Web for Earth and Environmental Terminology (SWEET) ontologies. The thesaurus is organized along with the ANSI/NISO Z39.19-2005 Guidelines for the Construction, Format, and Management of Monolingual Controlled Vocabularies, and is published using Simple Knowledge Organization System (SKOS) format. The IEDA thesaurus server provides classic web semantic features such as SPARQL, RESTful web services, and unique URI based on open source technologies.

Role of Rayleigh numbers on characteristics of double diffusive salt fingers

NASA Astrophysics Data System (ADS)

Rehman, F.; Singh, O. P.

2018-05-01

Double diffusion convection, driven by two constituents of the fluid with different molecular diffusivity, is widely applied in oceanography and large number of other fields like astrophysics, geology, chemistry and metallurgy. In case of ocean, heat (T) and salinity (S) are the two components with varying diffusivity, where heat diffuses hundred times faster than salt. Component (T) stabilizes the system whereas components (S) destabilizes the system with overall density remains stable and forms the rising and sinking fingers known as salt fingers. Recent observations suggest that salt finger characteristics such as growth rates, wavenumber, and fluxes are strongly depending on the Rayleigh numbers as major driving force. In this paper, we corroborate this observation with the help of experiments, numerical simulations and linear theory. An eigenvalue expression for growth rate is derived from the linearized governing equations with explicit dependence on Rayleigh numbers, density stability ratio, Prandtl number and diffusivity ratio. Expressions for fastest growing fingers are also derived as a function various non-dimensional parameter. The predicted results corroborate well with the data reported from the field measurements, experiments and numerical simulations.

This paper explores a vacant spot in the Cold War history of science: the development of research activities in the physical environmental sciences and in nuclear science and technology in Greenland. In the post-war period, scientific exploration of the polar areas became a strategically important element in American and Soviet defence policy. Particularly geophysical fields like meteorology, geology, seismology, oceanography, and others profited greatly from military interest. While Denmark maintained formal sovereignty over Greenland, research activities were strongly dominated by U.S. military interests. This paper sets out to summarize the limited current state of knowledge about activities in the environmental physical sciences in Greenland and their entanglement with military, geopolitical, and colonial interests of both the USA and Denmark. We describe geophysical research in the Cold War in Greenland as a multidimensional colonial endeavour. In a period of decolonization after World War II, Greenland, being a Danish colony, became additionally colonized by the American military. Concurrently, in a period of emerging scientific internationalism, the U.S. military "colonized" geophysical research in the Arctic, which increasingly became subject to military directions, culture, and rules.

Spaceborne microwave remote sensors provide perspectives of the earth surface and atmosphere which are of unique value in scientific studies of geomorphology, oceanic waves and topography, atmospheric water vapor and temperatures, vegetation classification and stress, ice types and dynamics, and hydrological characteristics. Microwave radars and radiometers offer enhanced sensitivities to the geometrical characteristics of the earth's surface and its cover, to water in all its forms - soil and vegetation moisture, ice, wetlands, oceans, and atmospheric water vapor, and can provide high-resolution imagery of the earth's surface independent of cloud cover or sun angle. A brief review of the historical development and principles of active and passive microwave remote sensing is presented, with emphasis on the unique characteristics of the information obtainable in the microwave spectrum and the value of this information to global geoscientific studies. Various spaceborne microwave remote sensors are described, with applications to geology, planetology, oceanography, glaciology, land biology, meteorology, and hydrology. A discussion of future microwave remote sensor technological developments and challenges is presented, along with a summary of future missions being planned by several countries.

SAR (Synthetic Aperture Radar). Earth observing system. Volume 2F: Instrument panel report

NASA Technical Reports Server (NTRS)

1987-01-01

The scientific and engineering requirements for the Earth Observing System (EOS) imaging radar are provided. The radar is based on Shuttle Imaging Radar-C (SIR-C), and would include three frequencies: 1.25 GHz, 5.3 GHz, and 9.6 GHz; selectable polarizations for both transmit and receive channels; and selectable incidence angles from 15 to 55 deg. There would be three main viewing modes: a local high-resolution mode with typically 25 m resolution and 50 km swath width; a regional mapping mode with 100 m resolution and up to 200 km swath width; and a global mapping mode with typically 500 m resolution and up to 700 km swath width. The last mode allows global coverage in three days. The EOS SAR will be the first orbital imaging radar to provide multifrequency, multipolarization, multiple incidence angle observations of the entire Earth. Combined with Canadian and Japanese satellites, continuous radar observation capability will be possible. Major applications in the areas of glaciology, hydrology, vegetation science, oceanography, geology, and data and information systems are described.

Science objectives, opportunities and requirements are discussed for the utilization of data from the Synthetic Aperture Radar (SAR) on the European First Remote Sensing Satellite, to be flown by the European Space Agency in the early 1990s. The principal applications of the imaging data are in studies of geophysical processes taking place within the direct-reception area of the Alaska SAR Facility in Fairbanks, Alaska, essentially the area within 2000 km of the receiver. The primary research that will be supported by these data include studies of the oceanography and sea ice phenomena of Alaskan and adjacent polar waters and the geology, glaciology, hydrology, and ecology of the region. These studies focus on the area within the reception mask of ASF, and numerous connections are made to global processes and thus to the observation and understanding of global change. Processes within the station reception area both affect and are affected by global phenomena, in some cases quite critically. Requirements for data processing and archiving systems, prelaunch research, and image processing for geophysical product generation are discussed.

Most people are familiar with tropical coral reefs, located in warm, well-illuminated, shallow waters. However, corals also exist hundreds and even thousands of meters below the ocean surface, where it is cold and completely dark. These deep-sea corals, also known as cold-water corals, have become a topic of interest due to conservation concerns over the impacts of trawling, exploration for oil and gas, and climate change. Although the existence of these corals has been known since the 1800s, our understanding of their distribution, ecology, and biology is limited due to the technical difficulties of conducting deep-sea research. DISCOVRE (DIversity, Systematics, and COnnectivity of Vulnerable Reef Ecosystems) is a new U.S. Geological Survey (USGS) program focused on deep-water coral ecosystems in the Gulf of Mexico. This integrated, multidisciplinary, international effort investigates a variety of topics related to unique and fragile deep-sea coral ecosystems from the microscopic level to the ecosystem level, including components of microbiology, population genetics, paleoecology, food webs, taxonomy, community ecology, physical oceanography, and mapping.

Jean Francheteau, pioneering marine geologist and geophysicist, AGU Fellow, and emeritus professor at the University of Brest (Université de Bretagne Occidentale), died on 21 July in St-Renan, Brittany, France, at the age of 67 after a long illness. With his passing, the field of Earth sciences lost a major contributor to the development of a definitive theory of plate tectonics and one of the first to make visual geological observations on the deep seafloor. Such scientific accomplishments, coupled with his personal charm and the ability to collaborate with researchers from many institutions, ensured that he had a huge influence not only on the world of research but also on teaching and the application of ethics to science. Jean arrived at Scripps Institution of Oceanography in La Jolla, Calif., in 1966 after obtaining a diploma in mining engineering at the prestigious Éole Nationale Supérieure de la Métallurgie et de l'Industrie des Mines in Nancy, France. He chose Victor Vacquier as his thesis supervisor and began working in Vic's lab with John Sclater, ostensibly on heat flow measurements.

The Center for Microbial Oceanography: Research and Education (C-MORE) is a NSF Science and Technology Center based at the University of Hawaii. The C-MORE education and outreach program offers a variety of resources and professional development opportunities for science educators, including online resources, participation in oceanography research cruises, teacher-training workshops, mini-grants to incorporate microbial oceanography-related content and activities into their classroom and, most recently, C- MORE science kits. C-MORE science kits provide hands-on classroom, field, and laboratory activities related to microbial oceanography for K-12 students. Each kit comes with complete materials and instructions, and is available free of charge to Hawaii's public school teachers. Several kits are available nationwide. C-MORE science kits cover a range of topics and technologies and are targeted at various grade levels. Here is a sampling of some available kits: 1) Marine Murder Mystery: The Case of the Missing Zooxanthellae. Students learn about the effect of climate change and other environmental threats on coral reef destruction through a murder-mystery experience. Participants also learn how to use DNA to identify a suspect. Grades levels: 3-8. 2) Statistical sampling. Students learn basic statistics through an exercise in random sampling, with applications to microbial oceanography. The laptops provided with this kit enable students to enter, analyze, and graph their data using EXCEL. Grades levels: 6-12. 3) Chlorophyll Lab. A research-quality fluorometer is used to measure the chlorophyll content in marine and freshwater systems. This enables students to compare biomass concentrations in samples collected from various locations. Grades levels: 9-12. 4) Conductivity-Temperature-Depth (CTD). Students predict how certain variables (e.g., temperature, pressure, chlorophyll, oxygen) vary with depth. A CTD, attached to a laptop computer, is deployed into deep water off a dock or a ship to collect real-time data and test their hypotheses. Grades levels: 9-12.

Hams, J. E.

2015-12-01

This session will present educational activities developed for an introductory Oceanography lecture and laboratory class by NOAA Teacher-at-Sea Jacquelyn Hams following participation in Leg 3 of Project DYNAMO (Dynamics of the Madden-Julian Oscillation) in November-December 2011. The Madden-Julian Oscillation (MJO) is an important tropical weather phenomenon with origins in the Indian Ocean that impacts many other global climate patterns such as the El Nino Southern Oscillation (ENSO), Northern Hemisphere monsoons, tropical storm development, and pineapple express events. The educational activities presented include a series of lessons based on the observational data collected during Project DYNAMO which include atmospheric conditions, wind speeds and direction, surface energy flux, and upper ocean turbulence and mixing. The lessons can be incorporated into any introductory Oceanography class discussion on ocean properties such as conductivity, temperature, and density, ocean circulation, and layers of the atmosphere. A variety of hands-on lessons will be presented ranging from short activities used to complement a lecture to complete laboratory exercises.

Climate-driven Oxygen Minimum Zone (OMZ) expansions in the geologic record provide an opportunity to characterize the spatial and temporal scales of OMZ change. Here we investigate OMZ expansion through the global-scale warming event of the most recent deglaciation (18-11 ka), an event with clear relevance to understanding modern anthropogenic climate change. Deglacial marine sediment records were compiled to quantify the vertical extent, intensity, surface area and volume impingements of hypoxic waters upon continental margins. By integrating sediment records (183-2,309 meters below sea level; mbsl) containing one or more geochemical, sedimentary or microfossil oxygenation proxies integrated with analyses of eustatic sea level rise, we reconstruct the timing, depth and intensity of seafloor hypoxia. The maximum vertical OMZ extent during the deglaciation was variable by region: Subarctic Pacific (~600-2,900 mbsl), California Current (~330-1,500 mbsl), Mexico Margin (~330-830 mbsl), and the Humboldt Current and Equatorial Pacific (~110-3,100 mbsl). The timing of OMZ expansion is regionally coherent but not globally synchronous. Subarctic Pacific and California Current continental margins exhibit tight correlation to the oscillations of Northern Hemisphere deglacial events (Termination IA, Bølling-Allerød, Younger Dryas and Termination IB). Southern regions (Mexico Margin and the Equatorial Pacific and Humboldt Current) exhibit hypoxia expansion prior to Termination IA (~14.7 ka), and no regional oxygenation oscillations. Our analyses provide new evidence for the geographically and vertically extensive expansion of OMZs, and the extreme compression of upper-ocean oxygenated ecosystems during the geologically recent deglaciation.

The Pale Blue Dot: Utilizing Real World Globes in High School and Undergraduate Oceanography Classrooms

Rogers, D. B.

2017-12-01

Geoscience classrooms have benefitted greatly from the use of interactive, dry-erasable globes to supplement instruction on topics that require three-dimensional visualization, such as seismic wave propagation and the large-scale movements of tectonic plates. Indeed, research by Bamford (2013) demonstrates that using three-dimensional visualization to illustrate complex processes enhances student comprehension. While some geoscience courses tend to bake-in lessons on visualization, other disciplines of earth science that require three-dimensional visualization, such as oceanography, tend to rely on students' prior spatial abilities. In addition to spatial intelligence, education on the three-dimensional structure of the ocean requires knowledge of the external processes govern the behavior of the ocean, as well as the vertical and lateral distribution of water properties around the globe. Presented here are two oceanographic activities that utilize RealWorldGlobes' dry-erase globes to supplement traditional oceanography lessons on thermohaline and surface ocean circulation. While simultaneously promoting basic plotting techniques, mathematical calculations, and unit conversions, these activities touch on the processes that govern global ocean circulation, the principles of radiocarbon dating, and the various patterns exhibited by surface ocean currents. These activities challenge students to recognize inherent patterns within their data and synthesize explanations for their occurrence. Spatial visualization and critical thinking are integral to any geoscience education, and the combination of these abilities with engaging hands-on activities has the potential to greatly enhance oceanography education in both secondary and postsecondary settings

Connecting Oceanography and Music

Capturing and retaining the interest of non-science majors in science classes can be difficult, no matter what type of science. At Berklee College of Music, this challenge is especially significant, as all students are music majors. In my Introductory Oceanography course, I use a final project as a way for the students to link class material with their own interests. The students may choose any format to present their projects to the class; however, many students write and perform original music. The performances of ocean-themed music have become a huge draw of the Introductory Oceanography course. In an effort to expand the reach of this music, several colleagues and I organized the first Earth Day event at Berklee, `Earthapalooza 2015.' This event included performances of music originally written for the final projects, as well as other musical performances, poetry readings, guest talks, and information booths. Although the idea of an Earth Day event is not new, this event is unique in that student performances really resonate with the student audience. Additionally, since many of these students will enter professional careers in the performance and recording industries, the potential exists for them to expose large audiences to the issues of oceanography through music. In this presentation, I will play examples of original student compositions and show video of the live student performances. I will also discuss the benefits and challenges of the final projects and the Earth Day event. Finally, I will highlight the future plans to continue ocean-themed music at Berklee.

Developing Online Oceanography at UCSB

NASA Astrophysics Data System (ADS)

Prothero, W. A.; Dodson, H.

2001-12-01

Oceanography at UCSB is an introductory general education science course taken by up to 200 students per quarter. The emphasis is on learning science process by engaging in authentic science activities that use real earth data. Recently, to increase student motivation, the course has been modified to include an Earth Summit framework. The online support being developed for this course is the first step in the creation of a completely online oceanography class. Foundation software was first tested in the class during Spring 2001. Online activities that are supported are writing and instructor feedback, online threaded discussion with live chat and graphics, automatically graded homeworks and games, auto graded quizzes with questions randomly selected from a database, and thought problems graded by the instructor(s). Future plans include integration with commercial course management software. To allow choice of assignments, all course activities totaled110%. Since grades were based on A=90-100, B=80-90, C= 70-80, etc, it was possible to get a better than A grade. Students see the effect (on their grade) of each assignment by calculating their current course grade. Course activities included (most of which are automatically graded): weekly lab homeworks, weekly mini-quizzes (10 multiple choice questions selected at random from a topic database), weekly thought questions (graded by the TA), 3 written assignments, and "Question of the Day" from lecture (credit given for handing it in), The online writing software allowed students to enter their writing, edit and link to graphic images, print the paper, and electronically hand it in. This has the enormous advantage of allowing the instructor and TA's convenient access to all student papers. At the end of the course, students were asked how effective each of the course activities were in learning the course material.

van der Merwe, Rudolph; Leen, Todd K; Lu, Zhengdong; Frolov, Sergey; Baptista, Antonio M

2007-05-01

We present neural network surrogates that provide extremely fast and accurate emulation of a large-scale circulation model for the coupled Columbia River, its estuary and near ocean regions. The circulation model has O(10(7)) degrees of freedom, is highly nonlinear and is driven by ocean, atmospheric and river influences at its boundaries. The surrogates provide accurate emulation of the full circulation code and run over 1000 times faster. Such fast dynamic surrogates will enable significant advances in ensemble forecasts in oceanography and weather.

The global ocean is an integrated living system where energy and matter transformations are governed by interdependent physical, chemical and biotic processes. Although the fundamentals of ocean physics and chemistry are well established, comprehensive approaches to describing and interpreting oceanic microbial diversity and processes are only now emerging. In particular, the application of genomics to problems in microbial oceanography is significantly expanding our understanding of marine microbial evolution, metabolism and ecology. Integration of these new genome-enabled insights into the broader framework of ocean science represents one of the great contemporary challenges for microbial oceanographers.

Multibeam synthetic aperture radar for global oceanography

NASA Technical Reports Server (NTRS)

Jain, A.

1979-01-01

A single-frequency multibeam synthetic aperture radar concept for large swath imaging desired for global oceanography is evaluated. Each beam iilluminates a separate range and azimuth interval, and images for different beams may be separated on the basis of the Doppler spectrum of the beams or their spatial azimuth separation in the image plane of the radar processor. The azimuth resolution of the radar system is selected so that the Doppler spectrum of each beam does not interfere with the Doppler foldover due to the finite pulse repetition frequency of the radar system.

Applications of optical sensors for high-frequency water-quality monitoring and research

USGS Publications Warehouse

Pellerin, Brian

2015-01-01

The recent commercial availability of in-situ optical sensors, together with new techniques for data collection and analysis, provides the opportunity to monitor a wide range of water-quality constituents over time scales during which environmental conditions actually change. Traditional approaches for data collection (daily to monthly discrete samples) are often limited by high sample collection, processing, and analytical costs, difficult site access, and logistical challenges, particularly for long-term sampling at a large number of sites. Optical sensors that continuously measure constituents in the environment by absorbance or fluorescence properties (Figure 1) have had a long history of use in oceanography for measuring highly resolved concentrations and fluxes of organic matter, nutrients, and algal material. However, much of the work using commercially-available optical sensors in rivers and streams has taken place in only the last few years. Figure 1. [NOT SHOWN] Optical sensor technology is now sufficiently developed to warrant broader application for research and monitoring in coastal and freshwater systems, and the United States Geological Survey (a U.S. science agency) is now using these sensors in a variety of research and monitoring programs to better understand water quality in-situ and in real-time. Examples are numerous and range from the applications of nitrate sensors for calculating loads to estuaries susceptible to hypoxia (Pellerin et al., 2014) to the use of fluorometers to estimate methymercury fluxes (Bergamaschi et al., 2011) and disinfection byproduct formation (Carpenter et al., 2013). Transmitting these data in real-time provides information that can be used for early trend detection, help identify monitoring gaps critical for water management, and provide science-based decision support across a range of issues related to water quality, freshwater ecosystems, and human health. Despite the value of these sensors, collecting data that meet high-quality standards requires investment in and adherence to tested and established methods and protocols for sensor operation and data management (Pellerin et al., 2013). For example, optical sensor measurements can be strongly influenced by a variety of matrix effects, including water temperature, inner filtering from highly colored water, and scattering of light by suspended particles (Downing et al., 2012). Characterizing and correcting sensors for these effects – as well as the continued development of common methodologies and protocols for sensor use – will be critical to ensuring comparable measurements across sites and over time. In addition, collaborative efforts such as the Nutrient Sensor Challenge (www.nutrients-challenge.org) will continue to accelerate the development, production and use of affordable, reliable and accurate sensors for a range of environments.

The role of Internal Solitary Waves on deep-water sedimentary processes: the case of up-slope migrating sediment waves off the Messina Strait

NASA Astrophysics Data System (ADS)

Droghei, Riccardo; Falcini, Federico; Martorelli, Eleonora; Casalbore, Daniele; Mosetti, Renzo; Salusti, Ettore; Sannino, Gianmaria; Santoleri, Rosalia; Chiocci, Francesco

Joint marine geology and physical oceanography studies seek to demonstrate the inherited connection between seafloor sedimentary processes and seawater dynamics in a fruitful exchange. While seafloor morphology highlights the long-term action of bottom currents, oceanographic models attempt to explain and predict morphogenetic processes and sedimentary pattern at the seafloor [Blodeaux, 2001; Martorelli et al., 2010; Belde et al., 2015]. A sand waves field we observed off the Messina Strait (Mediterranean Sea) give us the opportunity to demonstrate the value of such a multidisciplinary approach. We interpret these sand-waves as formed by tidal-induced internal solitary waves (ISWs) that generate within the Strait [Alpers and Salusti, 1983; Sapia and Salusti; 1987; Artale et al., 1990; Bradt et al., 1999]. We hypothesize that the deflected pattern (i.e., the depth-dependent orientation) of these sand waves is due to refraction of ISWs occurring at the interface between the Levantine Intermediate Water (LIW) and the Modified Atlantic Water (MAW), caused by interaction with a topographic mound; while the motion of sediment is caused by the bottom velocity field associated with the ISW trough. Both numerical and in situ data provide hints regarding the formation of the observed geometries and give useful information about their dynamics and migration rate. We believe that our work represents an innovative and promising link between the geological and oceanographic communities, adding some insights on the role of ISWs on sedimentary process and the structure of continental margins [Puig et al, 2004; Haren et al., 2013].

"Days of future passed" - climate change and carbon cycle history (Jean Baptiste Lamarck Medal Lecture)

NASA Astrophysics Data System (ADS)

Weissert, Helmut

2013-04-01

With the beginning of the fossil fuel age in the 19th century mankind has become an important geological agent on a global scale. For the first time in human history action of man has an impact on global biogeochemical cycles. Increasing CO2 concentrations will result in a perturbation of global carbon cycling coupled with climate change. Investigations of past changes in carbon cycling and in climate will improve our predictions of future climate. Increasing atmospheric CO2 concentrations will drive climate into a mode of operation, which may resemble climate conditions in the deep geological past. Pliocene climate will give insight into 400ppm world with higher global sea level than today. Doubling of pre-industrial atmospheric CO2 levels will shift the climate system into a state resembling greenhouse climate in the Early Cenozoic or even in the Cretaceous. Carbon isotope geochemistry serves as tool for tracing the pathway of the carbon cycle through geological time. Globally registered negative C-isotope anomalies in the C-isotope record are interpreted as signatures of rapid addition (103 to a few 104 years) of CO2 to the ocean-atmosphere system. Positive C-isotope excursions following negative spikes record the slow post-perturbation recovery of the biosphere at time scales of 105 to 106 years. Duration of C-cycle perturbations in earth history cannot be directly compared with rapid perturbation characterizing the Anthropocene. However, the investigation of greenhouse pulses in the geological past provides insight into different climate states, it allows to identify tipping points in past climate systems and it offers the opportunity to learn about response reactions of the biosphere to rapid changes in global carbon cycling. Sudden injection of massive amounts of carbon dioxide into the atmosphere is recorded in C-isotope record of the Early Cretaceous. The Aptian carbon cycle perturbation triggered changes in temperature and in global hydrological cycling. Changes in physical and chemical oceanography are reflected in widespread black shale deposition ("Oceanic Anoxic Event 1a"), in carbonate platform drowning and in biocalcification crises. "Days of future passed" (Moody Blues, 1967) reminds us that the past provides essential information needed for decisions to be made in the interest of mankind's future.

Satellite observations of the ice cover of the Kuril Basin region of the Okhotsk Sea and its relation to the regional oceanography

NASA Technical Reports Server (NTRS)

Wakatsuchi, Masaaki; Martin, Seelye

1990-01-01

For the period 1978-1982, this paper examines the nature of the sea ice which forms over the Kuril Basin of the Okhotsk Sea and describes the impact of this ice on the regional oceanography. The oceanographic behavior during the heavy ice season associated with the cold 1979 winter is compared with the behavior during the lighter ice years of 1980 and 1982. Examination of the oceanography in the Okhotsk and the adjacent Pacific shows that the early summer water column structure depends on the heat loss from the Okhotsk during the preceding ice season, the total amount of Okhotsk ice formation, and, specifically, the amount of the ice formation in the Kuril Basin. Following the 1979 ice season, the upper 200-300 m of the Kuril Basin waters were cooler, less saline, and richer in oxygen than for the other years. This modification appears to be a process local to the Kuril Basin, driven by eddy-induced mixing, local cooling, and ice melting.

Numerical Modeling of Ocean Circulation

NASA Astrophysics Data System (ADS)

Miller, Robert N.

2007-01-01

The modelling of ocean circulation is important not only for its own sake, but also in terms of the prediction of weather patterns and the effects of climate change. This book introduces the basic computational techniques necessary for all models of the ocean and atmosphere, and the conditions they must satisfy. It describes the workings of ocean models, the problems that must be solved in their construction, and how to evaluate computational results. Major emphasis is placed on examining ocean models critically, and determining what they do well and what they do poorly. Numerical analysis is introduced as needed, and exercises are included to illustrate major points. Developed from notes for a course taught in physical oceanography at the College of Oceanic and Atmospheric Sciences at Oregon State University, this book is ideal for graduate students of oceanography, geophysics, climatology and atmospheric science, and researchers in oceanography and atmospheric science. Features examples and critical examination of ocean modelling and results Demonstrates the strengths and weaknesses of different approaches Includes exercises to illustrate major points and supplement mathematical and physical details

Polar Seas Oceanography: An Integrated Case Study of the Kara Sea

NASA Astrophysics Data System (ADS)

Harms, Ingo

2004-02-01

What strikes first when browsing through this book is that the main title is misleading. Polar Seas Oceanography is, first of all, a book on ``an integrated case study of the Kara Sea,'' as the subtitle says. For readers who are interested more generally in polar oceanography, the book is probably the wrong choice. The Kara Sea is a rather shallow shelf sea within the Arctic Ocean, located between the Barents Sea to the west and the Laptev Sea to the east. The importance of the Kara Sea is manifold: climate change issues like ice formation and freshwater runoff, environmental problems from dumping of radioactive waste or oil exploitation, and finally, the Northern Sea route, which crosses large parts of the Kara Sea, underline the economical and ecological relevance of that region. In spite of severe climate conditions, the Kara Sea is relatively well investigated. This was achieved through intense oceanographic expeditions, aircraft surveys, and polar drift stations. Russian scientists from the Arctic and Antarctic Research Institute (AARI) carried out a major part of this outstanding work during the second half of the last century.

The 50th Anniversary of the International Indian Ocean Expedition: An Update on Current Planning Efforts and Progress

NASA Astrophysics Data System (ADS)

Hood, Raleigh; D'Adamo, Nick; Burkill, Peter; Urban, Ed; Bhikajee, Mitrasen

2014-05-01

The International Indian Ocean Expedition (IIOE) was one of the greatest international, interdisciplinary oceanographic research efforts of all time. Planning for the IIOE began in 1959 and the project officially continued through 1965, with forty-six research vessels participating under fourteen different flags. The IIOE motivated an unprecedented number of hydrographic surveys (and repeat surveys) over the course of the expedition covering the entire Indian Ocean basin. And it was an interdisciplinary endeavor that embraced physical oceanography, chemical oceanography, meteorology, marine biology, marine geology and geophysics. The end of 2015 will mark the 50th Anniversary of the completion of the IIOE. In the 50 years since the IIOE three fundamental changes have taken place in ocean science. The first is the deployment of a broad suite of oceanographic sensors on satellites that have dramatically improved the characterization of both physical and biological oceanographic variability. The second is the emergence of new components of the ocean observing system, most notably remote sensing and Argo floats. And the third is the development of ocean modeling in all its facets from short-term forecasting to seasonal prediction to climate projections. These advances have revolutionized our understanding of the global oceans, including the Indian Ocean. Compared to the IIOE era, we now have the capacity to provide a much more integrated picture of the Indian Ocean, especially if these new technologies can be combined with targeted and well-coordinated in situ measurements. In this presentation we report on current efforts to motivate an IIOE 50th Anniversary Celebration (IIOE-2). We envision this IIOE-2 as a 5-year expedition and effort beginning in 2015 and continuing through to 2020. An important objective of our planning efforts is assessing ongoing and planned research activities in the Indian Ocean in the 2015 to 2020 time frame, with the goal of embracing and helping to organize these activities as part of a larger coordinated 50th Anniversary research initiative. In addition we are working to motivate conferences, summer schools, data recovery, repeat line work and new process studies.

Should Data Frameworks be Inherently Multiscalar? A Use Case of the Living Atlas of the World

NASA Astrophysics Data System (ADS)

Wright, D. J.

2015-12-01

In addition to an individual research project, many researchers are involved in at least one major partnership, perhaps one ocean observatory, or one collaborative. The accompanying data framework may be focused on a subdiscipline of oceanography (i.e., marine geology and geophysics, physical oceanography, marine ecology, etc.) or particular study region. The data framework obviously exists to support research, but also collaboration in data collection, spatial analysis, visualization, and communication of the science to multiple audience. These interactions likely take place at multiple scales: the scale of the individual researcher, of small workgroups within a lab, or of inter-organizational collaboration. There are also frameworks that cut horizontally across discipline and region, connecting to broader national or global initiatives such as NSF EarthCube, other NSF-funded Research Coordination Networks, GEOSS, or ODIP. The Living Atlas of the World is presented as a use case of a data framework seeking to cut effectively across multiple spatial and temporal scales. The Living Atlas was first created in 2014 to make authoritative geographic information accessible via hosted cloud services so that users could more quickly address scientific and societal problems and decisions at spatial scales ranging from a small study area the entire globe, while using a range of interactive map functions to tell engaging narratives along the way (aka "story maps"). What began as a way to build trusted, authoritative, and freely available *basemaps* from data contributed online by the GIS community, has grown to a larger program extending far beyond basemap layers to satellite imagery, bathymetry, water column layers, and hydrology, as well elevation, human population, and 3D web scenes. The Living Atlas is continually under construction with new efforts that now extend beyond just the reading and serving of dataset, to the provisioning of spatial analysis on these *data services* in the cloud, as well as the crosswalking and sharing of workflows and use cases, additional apps for mobile, web, and desktop, community-building events where people gather face-to-face, and close interlinkages to other platforms such as ODIP and NSF EarthCube.

The offshore petroleum industry: The formative years, 1945-1962

NASA Astrophysics Data System (ADS)

Kreidler, Tai Deckner

1997-12-01

This dissertation is the first to examine the offshore oil industry that was born in the calm waters of the Gulf of Mexico. It describes the industry's origins and tracks its development as a consequence of a search for new oil frontiers. In addition, it elaborates how the oil industry moved into the marine province using available technology, and was driven by the economic urgency to compete and develop new territories. Enterprising drilling contractors and operators seized the offshore gamble, finding it possible to lower the economic and technological threshold by drawing directly from wartime research and surplus equipment. Though large oil companies had placed its indelible stamp upon the industry, the smaller, independent oil operators set the pace of early offshore development. As a technological frontier, offshore development depended upon creative and unconventional engineering. Unfamiliar marine conditions tested the imagination of oil industry engineering. The unorthodox methods of John Hayward of Barnsdall Oil and R. G. LeTourneau of LeTourneau, Inc. among others transformed the industry by blending petroleum and marine engineering. Grappling with alien marine conditions and lacking formal training, Hayward and LeTourneau merged a century of practical oil field knowledge and petroleum engineering with 2,000 years of shipbuilding experience. The Gulf of Mexico served as a fertile and protective environment for the development of a fledgling industry. With calm waters, lacking the tempestuous and stormy character of the Atlantic Ocean, with a gradual sea-floor slope and saturated with the highly productive salt dome reservoirs, the Gulf became the birth place of the modern offshore oil industry. Within its protective sphere, companies experimented and developed various technical and business adaptations. Operators used technology and business strategies that increased the opportunity for success. In addition, regional academic research institutes arose as a response to increasing work done for the offshore industry. Academic areas that developed included oceanography, physical oceanography, marine biology, marine geology, meteorology, and weather forecasting, During the formative era that ended in the late 1950s the industry had formed its technological and economic foundation in the Gulf, and stood poised to seize the initiative in the North Sea, the Middle East, the Far East, and Indonesia.

The future for the Global Sea Level Observing System (GLOSS) Sea Level Data Rescue

NASA Astrophysics Data System (ADS)

Bradshaw, Elizabeth; Matthews, Andrew; Rickards, Lesley; Aarup, Thorkild

2016-04-01

Historical sea level data are rare and unrepeatable measurements with a number of applications in climate studies (sea level rise), oceanography (ocean currents, tides, surges), geodesy (national datum), geophysics and geology (coastal land movements) and other disciplines. However, long-term time series are concentrated in the northern hemisphere and there are no records at the Permanent Service for Mean Sea Level (PSMSL) global data bank longer than 100 years in the Arctic, Africa, South America or Antarctica. Data archaeology activities will help fill in the gaps in the global dataset and improve global sea level reconstruction. The Global Sea Level Observing System (GLOSS) is an international programme conducted under the auspices of the WMO-IOC Joint Technical Commission for Oceanography and Marine Meteorology. It was set up in 1985 to collect long-term tide gauge observations and to develop systems and standards "for ocean monitoring and flood warning purposes". At the GLOSS-GE-XIV Meeting in 2015, GLOSS agreed on a number of action items to be developed in the next two years. These were: 1. To explore mareogram digitisation applications, including NUNIEAU (more information available at: http://www.mediterranee.cerema.fr/logiciel-de-numerisation-des-enregistrements-r57.html) and other recent developments in scanning/digitisation software, such as IEDRO's Weather Wizards program, to see if they could be used via a browser. 2. To publicise sea level data archaeology and rescue by: • maintaining and regularly updating the Sea Level Data Archaeology page on the GLOSS website • strengthening links to the GLOSS data centres and data rescue organisations e.g. linking to IEDRO, ACRE, RDA • restarting the sea level data rescue blog with monthly posts. 3. Investigate sources of funding for data archaeology and rescue projects. 4. Propose "Guidelines" for rescuing sea level data. These action items will aid the discovery, scanning, digitising and quality control of analogue tide gauge charts and sea level ledgers and improve the quality, quantity and availability of long-term sea level data series.

Making an outreach movie -The Puerto Rico Trench: Exploring the deepest place in the Atlantic Ocean

NASA Astrophysics Data System (ADS)

ten Brink, J.; ten Brink, U. S.

2004-12-01

A new movie will be screened that describes the exploration of the Puerto Rico trench with a multibeam echosounder and its significance to scientific research and tsunami hazard assessment. The movie audience is the general public including high school students. It aims to stimulate interest in Oceanography and to demonstrate scientific processes as they are applied in Geological Oceanography. The extensive use of 3-D visualization fly-bys over the dramatic ocean floor of the Puerto Rico trench should be particularly appealing to a generation growing up on video games and 3-D visualizations. The film is the product of close cooperation between a film maker and a scientist through all stages of its production and post production. This level of close cooperation is necessary because scientists' and film makers' approaches to presentation of information can differ greatly. In making an educational or outreach movie, the scientist must be responsible for the contents of the message, but the film maker has to design an effective delivery method. The creation of this movie was the result of following stages: (1) live action filming during a short research cruise; (2) generating 3-D fly-by using Fledermausr software; (3) rendering the fly-by sequences to a high-definition film; (4) collecting still photos and other supporting material; (5) generating graphs illustrating crucial scientific information and concepts; (6) preparing the script for voiceover narration; (7) working with a professional actor in order to ensure accurate delivery of the information. The biggest challenge in making the movie was the editing stage when the different elements of the movie were put together, incorporating music and voiceover into an aesthetically pleasing, interesting, and above all, scientifically accurate and coherent movie. Post-editing steps included replication of the master copy, package design, and distribution. The movie was completed in several weeks on a modest budget, thanks to modern desktop digital video, editing, voice recording, mixing, and replication technologies. Free copies of the film can be obtained by contacting the second author.

Sea Level Changes: Determination and Effects

NASA Astrophysics Data System (ADS)

Woodworth, P. L.; Pugh, D. T.; DeRonde, J. G.; Warrick, R. G.; Hannah, J.

The measurement of sea level is of fundamental importance to a wide range of research in climatology, oceanography, geology and geodesy. This volume attempts to cover many aspects of the field. The volume opens with a description by Bolduc and Murty of one of the products stemming from the development of tide gauge networks in the northern and tropical Atlantic.

The measurement of sea level is of fundamental importance to a wide range of research in climatology, oceanography, geology and geodesy. This volume attempts to cover many aspects of the field. The volume opens with a description by Bolduc and Murty of one of the products stemming from the development of tide gauge networks in the northern and tropical Atlantic. This work is relevant to the growth of the Global Sea Level Observing System (GLOSS), the main goal of which is to provide the world with an efficient, coherent sea level monitoring system for oceanographic and climatological research. The subsequent four papers present results from the analysis of existing tide gauge data, including those datasets available from the Permanent Service for Mean Sea Level and the TOGA Sea Level Center. Two of the four, by Wróblewski and by Pasarić and Orlić, are concerned with European sea level changes, while Yu Jiye et al. discuss inter-annual changes in the Pacific, and Wang Baocan et al. describe variability in the Changjiang estuary in China.

In the post-TOPEX era, satellite radar altimeters will be developed with the capability of measuring the earth's surface topography over a wide swath of coverage, rather than just at the satellite's nadir. The identification of potential spacecraft flight missions in the future was studied. The best opportunity was found to be the Earth Observing System (EOS). It is felt that an instrument system that has a broad appeal to the earth sciences community stands a much better chance of being selected as an EOS instrument. Consequently, the Topography and Rain Radar Imager (TARRI) will be proposed as a system that has the capability to profile the Earth's topography regardless of the surface type. The horizontal and height resolutions of interest are obviously significantly different over land, ice, and water; but, the use of radar to provide an all-weather observation capability is applicable to the whole earth. The scientific guidance for the design and development of this instrument and the eventual scientific utilization of the data produced by the TARRI will be provided by seven science teams. The teams are formed around scientific disciplines and are titled: Geology/Geophysics, Hydrology/Rain, Oceanography, Ice/Snow, Geodesy/Orbit/Attitude, Cartography, and Surface Properties/Techniques.

Double-diffusion convection is one of the most important non-mechanically driven mixing processes. Its importance has been particular recognized in oceanography, material science, geology, and planetary physics. Double-diffusion occurs in a fluid in which there are gradients of two (or more) properties with different molecular diffusivities and of opposing effects on the vertical density distribution. It has two primary modes: salt finger and diffusive convection. Recently, the importance of diffusive convection has aroused more interest due to its impact to the diapycnal mixing in the interior ocean and the ice and the ice-melting in the Arctic and Antarctic Oceans. In our recent work, we constructed a length scale of energy-containing eddy and proposed a new layer thickness parameterization of diffusive convection by using the laboratory experiment and in situ observations in the lakes and oceans. The new parameterization can well describe the laboratory convecting layer thicknesses (0.01 0.1 m) and those observed in oceans and lakes (0.1 1000 m). This work was supported by China NSF Grants (41476167,41406035 and 41176027), NSF of Guangdong Province, China (2016A030311042) and the Strategic Priority Research Program of the Chinese Academy of Sciences (XDA11030302).

Axial Seamount, located on the Juan de Fuca spreading ridge 300 miles off the Oregon coast, is an active volcano whose summit caldera lies 1500 m beneath the sea surface. Ongoing construction of the Regional Scale Nodes (RSN) cabled observatory by the University of Washington (funded by the NSF Ocean Observatories Initiative) has allowed for exploration of recent lava flows and active hydrothermal vents using HD video mounted on the ROVs, ROPOS and JASON II. College level oceanography/marine geology online laboratory exercises referred to as Online Concept Modules (OCMs) have been created using video and video frame-captured mosaics to promote skill development for characterizing and quantifying deep sea environments. Students proceed at their own pace through a sequence of short movies with which they (a) gain background knowledge, (b) learn skills to identify and classify features or biota within a targeted environment, (c) practice these skills, and (d) use their knowledge and skills to make interpretations regarding the environment. Part (d) serves as the necessary assessment component of the laboratory exercise. Two Axial Seamount-focused OCMs will be presented: 1) Lava Flow Characterization: Identifying a Suitable Cable Route, and 2) Assessing Hydrothermal Vent Communities: Comparisons Among Multiple Sulfide Chimneys.

Integrated studies of active volcanic systems for the purpose of long-term monitoring and forecast and short-term eruption prediction require large numbers of data-sets from various disciplines. A modern database concept has been developed for managing and analyzing multi-disciplinary volcanological data-sets. The GEOWARN project (choosing the "Kos-Yali-Nisyros-Tilos volcanic field, Greece" and the "Campi Flegrei, Italy" as test sites) is oriented toward potentially active volcanoes situated in regions of high geodynamic unrest. This article describes the volcanological database of the spatial and temporal data acquired within the GEOWARN project. As a first step, a spatial database embedded in a Geographic Information System (GIS) environment was created. Digital data of different spatial resolution, and time-series data collected at different intervals or periods, were unified in a common, four-dimensional representation of space and time. The database scheme comprises various information layers containing geographic data (e.g. seafloor and land digital elevation model, satellite imagery, anthropogenic structures, land-use), geophysical data (e.g. from active and passive seismicity, gravity, tomography, SAR interferometry, thermal imagery, differential GPS), geological data (e.g. lithology, structural geology, oceanography), and geochemical data (e.g. from hydrothermal fluid chemistry and diffuse degassing features). As a second step based on the presented database, spatial data analysis has been performed using custom-programmed interfaces that execute query scripts resulting in a graphical visualization of data. These query tools were designed and compiled following scenarios of known "behavior" patterns of dormant volcanoes and first candidate signs of potential unrest. The spatial database and query approach is intended to facilitate scientific research on volcanic processes and phenomena, and volcanic surveillance.

In the Footsteps of Roger Revelle: Seagoing Oceanography for Middle School Science

Now in its fourth year, "In the Footsteps of Roger Revelle" (IFRR) is a middle school science education program that draws student interest, scientific content and coherence with National Science Standards from real-time research at sea in fields of physical science. As a successful collaboration involving Scripps Institution of Oceanography (SIO), Woods Hole Oceanographic Institution (WHOI), National Oceanic and Atmospheric Administration (NOAA), Office of Naval Research (ONR), National Science Foundation (NSF), San Diego County Office of Education (SDCOE), and San Marcos Middle School (SMMS), IFRR brings physical oceanography and related sciences to students at the San Marcos Middle School in real-time from research vessels at sea using SIO's HiSeasNet satellite communication system. With their science teacher on the ship as an education outreach specialist or ashore guiding students in their interactions with selected scientists at sea, students observe shipboard research being carried out live via videoconference, daily e-mails, interviews, digital whiteboard sessions, and web interaction. Students then research, design, develop, deploy, and field-test their own data-collecting physical oceanography instruments in their classroom. The online interactive curriculum encourages active inquiry with intellectually stimulating problem-solving, enabling students to gain critical insight and skill while investigating some of the most provocative questions of our time, and seeing scientists as role- models. Recent science test scores with IFRR students have shown significant increases in classes where this curriculum has been implemented as compared to other classes where the traditional curriculum has been used. IFRR has provided students in the San Diego area with a unique opportunity for learning about oceanographic research, which could inspire students to become oceanographers or at least scientifically literate citizens - a benefit for a country that depends increasingly on technically proficient personnel, and a benefit for society at large.

Teaching with Games: Online Resources and Examples for Entry Level Courses

Teed, R.; Manduca, C.

Using games to teach introductory geoscience can motivate students to enthusiastically learn material that they might otherwise condemn as "boring". A good educational game is one that immerses the players in the material and engages them for as long as it takes to master that material. There are some good geoscience games already available, but instructors can also create their own, suitable to their students and the content that they are teaching. Game-Based Learning is a module on the Starting Point website for faculty teaching entry level geosciences. It assists faculty in using games in their teaching by providing a description of the features of game-based learning, why you would use it, how to use games to teach geoscience, examples, and references. Other issues discussed include the development of video games for teaching, having your students create educational games, what makes a good game, handling competition in the classroom, and grading. The examples include descriptions of and rules for a GPS treasure hunt, a geology quiz show, and an earthquake game, as well as links to several online geological video games, and advice on how to design a paleontology board game. Starting Point is intended to help both experienced faculty and new instructors meet the challenge of teaching introductory geoscience classes, including environmental science and oceanography as well as more traditional geology classes. For many students, these classes are both the first and the last college-level science class that they will ever take. They need to learn enough about the Earth in that one class to sustain them for many decades as voters, consumers, and sometimes even as teachers. Starting Point is produced by a group of authors working with the Science Education Resource Center. It contains dozens of detailed examples categorized by geoscience topic with advice about using them and assessing learning. Each example is linked to one of many modules, such as Game-Based Learning, Interactive Lectures, or Using an Earth History Approach. These modules describe teaching tools and techniques, provide examples and advice about using them in an introductory geoscience class, and give instructors details on how to create their own exercises.

Real-Time Earthquake Analysis for Disaster Mitigation (READI) Network

NASA Astrophysics Data System (ADS)

Bock, Y.

2014-12-01

Real-time GNSS networks are making a significant impact on our ability to forecast, assess, and mitigate the effects of geological hazards. I describe the activities of the Real-time Earthquake Analysis for Disaster Mitigation (READI) working group. The group leverages 600+ real-time GPS stations in western North America operated by UNAVCO (PBO network), Central Washington University (PANGA), US Geological Survey & Scripps Institution of Oceanography (SCIGN project), UC Berkeley & US Geological Survey (BARD network), and the Pacific Geosciences Centre (WCDA project). Our goal is to demonstrate an earthquake and tsunami early warning system for western North America. Rapid response is particularly important for those coastal communities that are in the near-source region of large earthquakes and may have only minutes of warning time, and who today are not adequately covered by existing seismic and basin-wide ocean-buoy monitoring systems. The READI working group is performing comparisons of independent real time analyses of 1 Hz GPS data for station displacements and is participating in government-sponsored earthquake and tsunami exercises in the Western U.S. I describe a prototype seismogeodetic system using a cluster of southern California stations that includes GNSS tracking and collocation with MEMS accelerometers for real-time estimation of seismic velocity and displacement waveforms, which has advantages for improved earthquake early warning and tsunami forecasts compared to seismic-only or GPS-only methods. The READI working group's ultimate goal is to participate in an Indo-Pacific Tsunami early warning system that utilizes GNSS real-time displacements and ionospheric measurements along with seismic, near-shore buoys and ocean-bottom pressure sensors, where available, to rapidly estimate magnitude and finite fault slip models for large earthquakes, and then forecast tsunami source, energy scale, geographic extent, inundation and runup. This will require cooperation with other real-time efforts around the Pacific Rim in terms of sharing, analysis centers, and advisory bulletins to the responsible government agencies. The IAG's Global Geodetic Observing System (GGOS), in particular its natural hazards theme, provides a natural umbrella for achieving this objective.

SeaDataNet II - EMODNet Bathymetry - building a pan-European infrastructure for marine and ocean data management and a digital high resolution bathymetry for European seas

The second phase of the project SeaDataNet is well underway since October 2011. The main objective is to improve operations and to progress towards an efficient data management infrastructure able to handle the diversity and large volume of data collected via research cruises and monitoring activities in European marine waters and global oceans. The SeaDataNet infrastructure comprises a network of interconnected data centres and a central SeaDataNet portal. The portal provides users a unified and transparent overview of the metadata and controlled access to the large collections of data sets, managed by the interconnected data centres, and the various SeaDataNet standards and tools,. SeaDataNet is also setting and governing marine data standards, and exploring and establishing interoperability solutions to connect to other e-infrastructures on the basis of standards of ISO (19115, 19139), OGC (WMS, WFS, CS-W and SWE), and OpenSearch. The population of directories has increased considerably in cooperation and involvement in associated EU projects and initiatives. SeaDataNet now gives overview and access to more than 1.6 million data sets for physical oceanography, chemistry, geology, geophysics, bathymetry and biology from more than 100 connected data centres from 34 countries riparian to European seas. Access to marine data is also a key issue for the implementation of the EU Marine Strategy Framework Directive (MSFD). The EU communication 'Marine Knowledge 2020' underpins the importance of data availability and harmonising access to marine data from different sources. SeaDataNet qualified itself for an active role in the data management component of the EMODnet (European Marine Observation and Data network) that is promoted in the EU Communication. Starting 2009 EMODnet pilot portals have been initiated for marine data themes: digital bathymetry, chemistry, physical oceanography, geology, biology, and seabed habitat mapping. These portals are being expanded to all European sea regions as part of EMODnet Phase 2, which started mid 2013. EMODnet encourages more data providers to come forward for data sharing and participating in the process of making complete overviews and homogeneous data products. The EMODnet Bathymetry project is very illustrative for the synergy between SeaDataNet and EMODnet and added value of generating public data products. The project develops and publishes Digital Terrain Models (DTM) for the European seas. These are produced from survey and aggregated data sets. The portal provides a versatile DTM viewing service with many relevant map layers and functions for retrieving. A further refinement is taking place as part of phase 2. The presentation will highlight key achievements in SeaDataNet II and give further details and views on the new EMODNet Digital Bathymetry for European seas as to be released early 2015.

United States progress in equatorial oceanography is reviewed, focusing on the low frequency response of upper equatorial oceans to forcing by the wind. Variations of thermocline depth, midocean currents, and boundary currents are discussed. The factors which determine sea surface temperature (SST) variability in equatorial oceans are reviewed, and the status of understanding of the most spectacular manifestation of SST variability, the El Nino-Southern Oscillation phenomenon, is discussed. The problem of observing surface winds, regarded as a fundamental factor limiting understanding of the equatorial oceans, is addressed. Finally, an attempt is made to identify those current trends which are expected to bear fruit in the near and distant future.

Is the Oceanography of the New Zealand Subantarctic Region Responding to the Tropics?

NASA Astrophysics Data System (ADS)

Forcen-Vazquez, A. N.

2016-02-01

The Campbell Plateau, south of New Zealand plays an important role in New Zealand's regional climate and its oceanography may have a significant impact on fluctuations in fish stocks and marine mammal populations. It is located between the Subtropical and Subantarctic Fronts and exhibits marked variability over long time scales. It has been previously assumed, because of its location, that the Campbell Plateau oceanography is driven by Subantarctic and polar processes. Recent analysis, presented here, suggests this in not the case, and instead forcing comes from the tropics and subtropics. This is supported by positive correlations of Sea Level Anomalies (SLA) and Sea Surface Temperature (SST) with the Southern Oscillation Index (SOI) with SOI leading changes on the Campbell Plateau by two months for SLA and seven months for SST. Here we will present evidence of the similarity between the Campbell Plateau and the Tasman Sea SLA trends which suggests a closer relationship with the subtropical region. Satellite collected SLA data and SST from the last two decades are investigated to understand trends and long-term variability over the Campbell Plateau and its relationship with the surrounding open ocean, and other potential remote drivers of variability.

Retaining STEM women with community-based mentoring

Lozier, M.

2011-12-01

While women have been graduating from physical oceanography programs in increasing numbers for the past two decades, the number of women occupying senior positions in the field remains relatively low. Thus, the disparity between the percentages of women at various career stages seems to be related to the retention of those completing graduate school in physical oceanography, not in recruiting women to the field. Studies indicate that a positive mentoring experience is strongly correlated with success in science, and as such, MPOWIR (Mentoring Physical Oceanography Women to Increase Retention) provides this essential mentoring to physical oceanographers from late graduate school through their early careers. Our network includes over 400 scientists at 70 institutions participating in a variety of online and face-to-face mentoring opportunities. The MPOWIR website (www.mpowir.org) includes resources for junior scientists, ways to get involved, data and career profiles, and a blog with job postings and relevant information. In October 2011, we will hold the third Pattullo conference to bring mentors and mentees together. The 43 participants at this conference will share their research, attend professional development sessions, and openly discuss issues related to the retention of young scientists in the field.

Smart, sustainable and inclusive Blue Growth means also knowing past technology and the paths followed by ancients in order to understand and monitor marine environments. In general, history of Science is a matter that is not enough explored and explained or promoted in high schools or university official programmes, and, usually, scientist do not consider it as an important part of their curricula. However, bad or good ideas, abandoned or forgotten beliefs, concepts, opinions, do still have a great potential for inspiring present and future scientists, no matter in which historical period they may have been formulated: they should be always be taken into consideration, critically examined and observed by a very close point of view, not just as part of the intellectual framework of some obsolete 'Cabinet of Curiosities' with limited access except for the chosen few. Moreover, history of Science should be transmitted in a more practical way, with hands-on labs showing the limits and challenges that prior generations of ocean explorers, investigators and seafarers had to face in order to answer to crucial questions as self-orientation in open sea, understanding main currents and waves, predicting meteorological conditions for a safe navigation. Oceanography is a relatively young branch of science, and still needs further approvals and knowledge (National Science Foundation, 2000). The Scientific Dissemination Group (SDG) "La Spezia Gulf of Science" - made up by Research Centres, Schools and Cultural associations located in La Spezia (Liguria, Italy) - has a decadal experience in initiatives aimed at people and groups of people of all ages, who are keen on science or who can be guided in any case to take an interest in scientific matters (Locritani et al., 2015). Amongst the SDG activities, the tight relationship with the Historical Oceanography Society, the Italian Navy and the Naval Technical Museum (that collects a rich heritage of civilization, technology and culture witnesses, related to the naval history of seamanship from the origins up to nowadays), allowed the creation of a special educational format based on Historical Oceanography, for university and high school students as an integration for their curriculum. The Historical Oceanography Society has provided the major knowledges included in the ancient volumes of its archive, thanks to the availability of its members that also held theoretical and practical lessons during the course. The present paper will describe the one-week special course (about 60 hours of theory and practice with technical visits to Research centres and Museums) that has been planned to be carried out on board of the Italian Training Navy Ship (A. Vespucci) and has been organized in order to give the hints about on board life, as well as theoretical lessons on modern and historical oceanography, hands-on labs on oceanographic instruments from public and private collections, physiology of diving techniques and astronomy. The general aim of this course has been, hence, to give to excellent students all those technological but also creative and imaginative features of our past. References M. Locritani, I. Batzu, C.

Overexploitation and climate change are increasingly causing unanticipated changes in marine ecosystems, such as higher variability in fish recruitment and shifts in species dominance. An ecosystem-based approach to fisheries attempts to address these effects by integrating populations, food webs and fish habitats at different scales. Ecosystem models represent indispensable tools to achieve this objective. However, a balanced research strategy is needed to avoid overly complex models. Ecosystem oceanography represents such a balanced strategy that relates ecosystem components and their interactions to climate change and exploitation. It aims at developing realistic and robust models at different levels of organisation and addressing specific questions in a global change context while systematically exploring the ever-increasing amount of biological and environmental data.

Life on Earth most likely originated as microorganisms in the sea. Over the past approximately 3.5 billion years, microorganisms have shaped and defined Earth's biosphere and have created conditions that have allowed the evolution of macroorganisms and complex biological communities, including human societies. Recent advances in technology have highlighted the vast and previously unknown genetic information that is contained in extant marine microorganisms, from new protein families to novel metabolic processes. Now there is a unique opportunity, using recent advances in molecular ecology, metagenomics, remote sensing of microorganisms and ecological modelling, to achieve a comprehensive understanding of marine microorganisms and their susceptibility to environmental variability and climate change. Contemporary microbial oceanography is truly a sea of opportunity and excitement.

Coupling biology and oceanography in models.

Fennel, W; Neumann, T

The dynamics of marine ecosystems, i.e. the changes of observable chemical-biological quantities in space and time, are driven by biological and physical processes. Predictions of future developments of marine systems need a theoretical framework, i.e. models, solidly based on research and understanding of the different processes involved. The natural way to describe marine systems theoretically seems to be the embedding of chemical-biological models into circulation models. However, while circulation models are relatively advanced the quantitative theoretical description of chemical-biological processes lags behind. This paper discusses some of the approaches and problems in the development of consistent theories and indicates the beneficial potential of the coupling of marine biology and oceanography in models.

After the Challenger expedition (1872-1878), other nations started to show interest in oceanographic research and organizing their own expeditions. As of 1885, Prince Albert I of Monaco conducted oceanographic campaigns with the collaboration of some of the best marine biologists and physical oceanographers of the day, inventing new techniques and instruments for the oceanographic work. Prince Albert's scientific activity certainly helped kindle the interest of his friend, Dom Carlos I, king of Portugal, in the study of the oceans and marine life. Both shared the need to use photography to document their studies. This article analyzes the role of scientific photography in oceanography, especially in the expeditions organized by the Portuguese monarch.

Federal responsibility for oil and gas development on the U.S. outer continental shelf (OCS) resides with the Minerals Management Service (MMS) of the U.S. Department of the Interior (DOI). The DOI's Environmental Studies Program (ESP) is the program through which MMS conducts environmental studies on the OCS and collects information to prepare environmental impact statements (EISs). It appeared to MMS in 1986 that the time was ripe to assess the status of the present program and to explore the needs for future studies. MMS requested an evaluation of the adequacy and applicability of ESP studies, a review of the generalmore » state of knowledge in the appropriate disciplines, and recommendations for future studies. Three panels were established, one of which, the Physical Oceanography Panel, investigated the physical oceanographic aspects of the ESP, the subject of the report, which is the first of three in a series. In reviewing the ESP's physical oceanography program, the panel evaluated the quality and relevance of studies carried out in waters under federal control, which extend from the limits of state jurisdictions (3-12 miles offshore) and include the central and outer continental shelf waters and the continental slope.« less

Oceanography and marine ecosystem research are inherently interdisciplinary fields of study that generate and require access to a wide variety of measurements. In late 2006 the Biological and Chemical Oceanography Sections of the National Science Foundation (NSF) Geosciences Directorate Division of Ocean Sciences (OCE) funded the Biological and Chemical Oceanography Data Management Office (BCO-DMO). In late 2010 additional funding was contributed to support management of research data from the NSF Office of Polar Programs Antarctic Organisms & Ecosystems Program. The BCO-DMO is recognized in the 2011 Division of Ocean Sciences Sample and Data Policy as one of several program specific data offices that support NSF OCE funded researchers. BCO-DMO staff members offer data management support throughout the project life cycle to investigators from large national programs and medium-sized collaborative research projects, as well as researchers from single investigator awards. The office manages and serves all types of oceanographic data and information generated during the research process and contributed by the originating investigators. BCO-DMO has built a data system that includes the legacy data from several large ocean research programs (e.g. United States Joint Global Ocean Flux Study and United States GLOBal Ocean ECosystems Dynamics), to which data have been contributed from recently granted NSF OCE and OPP awards. The BCO-DMO data system can accommodate many different types of data including: in situ and experimental biological, chemical, and physical measurements; modeling results and synthesis data products. The system enables reuse of oceanographic data for new research endeavors, supports synthesis and modeling activities, provides availability of "real data" for K-12 and college level use, and provides decision-support field data for policy-relevant investigations. We will present an overview of the data management system capabilities including: map-based and text-based data discovery and access systems; recent enhancements to data search tools; data export and download utilities; and strategic use of controlled vocabularies to facilitate data integration and to improve data system interoperability.

Marine geology and bathymetry of nearshore shelf of Chukchi Sea, Ogotoruk Creek area, northwest Alaska

During July and August 1958 the U.S. Geological Survey conducted a study in behalf of the Atomic Energy Commission of the oceanography, bathymetry, and marine geology of the nearshore shelf of the Chukchi Sea off the Ogotoruk Creek area, northwest Alaska. Ogotoruk Creek enters the Chukchi Sea about 32 miles southeast of the large cuapate spit of Point Hope at long 165 degrees 4446 W. and lat 68 degrees 0551 N. The Ogotoruk Creek area extends approximately 10 miles west and 7 miles east of the creek mouth. Knowledge of the marine geology and oceanography is confined primarily to the nearshore shelf, which includes about 70 square miles of the shelf and is defined as the sea floor lying shoreward of the 50-foot submarine contour. The 50-foot contour generally lies from 2 to 4 miles from shore. Submarine topography was studied to a distance of 15 miles from shore over an area of approximately 340 square miles. A northwest coastal current flows past the Ogotoruk Creek area and during July and August averaged 0.5 mile per hour. Persistent northerly winds cause general upwelling near shore and at times of pronounced upwelling the coastal current was reversed or appreciably reduced in speed. Longshore currents shoreward of the breaker zone averaged 0.3 mile per hour and moved to the east for the greater part of the time of the study. The overall seaward slope of the inner 15 miles of the Chukchi shelf from a depth of 40 to 135 feet is approximately 0 degrees 04, or about 6 feet per mile. Slopes near shore to depths of 15-20 feet are steep and average 2 degrees 30. Beyond these depths they increase gradually out to a depth of 40-45 feet. Seaward of this point the shelf is flattest and slopes are as low as 0 degree 01. This terrace or flat part of the nearshore shelf is about 2 miles wide and descends to a depth of 50-55 feet beyond which the gradient increases to about 0 degree 06. At depths greater than 85 feet the submarine declivity gradually decreases to 0 degree 03 at a distance of 15 miles from shore. A flat-bottomed trough, Ogotoruk Seavalley, heads about a quarter of a mile from shore off the mouth of Ogotoruk Creek. The shallow seavalley averages only 6 feet in relief and extends 15 miles from shore to a depth of 135 feet. A number of smaller channels also indent the gentle sloping inner Chukchi shelf east of the seavalley and nearshore west of it. Many outcrops of Paleozoic and Mesozoic formations on the nearshore shelf indicate that it is a wave-planed platform. Wave planation is thought to have taken place primarily in Sangamon and rpre-Sangamon time (approximately 100,000 to 1,000,000 years ago). Ogotoruk Seavalley is believed to be a drowned subaerial valley which was excavated by Ogotoruk Creek during periods of glacially depressed sea level. Unconsolidated sediments overlying the nearshore shelf are chiefly slightly rounded residual gravel which have been derived from submerged outcrops. Detrital sand and silt, contributed from the nearby coastal area during Recent time, overlie the shelf near shore and at depth as much as 50 feet seaward of segments of the coast underlain by fine-grained clastic rocks of Mesozoic age. Owing to a small volume of detrital clasts contributed by the coastal area detrital sedimentation is not prominent over the nearshore shelf. Beaches fronting the Ogotoruk Creek area are 30-260 feet wide, range from less than 10 to about 25 feet thick, and are composed of sandy gravel having a median diameter of about 10 mm. Rounded clasts of greywacke, siltstone, limestone, and chert are the principal constituents of the gravel. Longshore currents accompanying moderate storms transport gravel and sand parallel to shore at rates of 5 cubic yards per hour. Sediment transported by longshore currents accumulates as spits at stream mouths and as areas of new beach below rocky headlands.

The social oceanography of top oceanic predators and the decline of sharks: A call for a new field

NASA Astrophysics Data System (ADS)

Jacques, Peter J.

2010-07-01

The decline of top oceanic predators (TOPs), such as great sharks, and worldwide erosion of the marine food web is among the most important functional changes in marine systems. Yet, even though human pressures on sharks are one of the most important factors in the collapse of TOPs, the social science of shark fishing has not kept pace with the biophysical science. Such a gap highlights the need for a marine social science, and this paper uses the case of sharks to illustrate some advances that a coherent marine social science community could bring to science and sustainability, and calls for the development of this new field. Social oceanography is proposed as a “discursive space” that will allow multiple social science and humanities disciplines to holistically study and bring insight to a diverse but essential community. Such a community will not provide answers for the physical sciences, but it will add a new understanding of the contingencies that riddle social behavior that ultimately interact with marine systems. Such a field should reflect the broad and diverse approaches, epistemologies, philosophies of science and foci that are in the human disciplines themselves. Social oceanography would complete the triumvirate of biological and physical oceanography where human systems profoundly impact these other areas. This paper tests the theory that institutional rules are contingent on social priorities and paradigms. I used content analysis of all available (1995-2006) State of the World Fisheries and Aquaculture (SOFIA) reports from the United Nations Food and Agricultural Organization (FAO) to measure the symbolic behavior-i.e., what they say-as an indication of the value of sharks in world fisheries. Similar tests were also performed for marine journals and the Convention on Migratory Species of Wild Animals to corroborate these findings. Then, I present an institutional analysis of all international capacity building and regulatory institutions as they pertain to sharks. We find that sharks are not a high priority compared to other fisheries; and, amongst issue areas, ecological concerns are overshadowed by a paradigm of economism (economic values are demonstrated above all others). Further, sharks have no global binding institutions for conservation, and only new and problematic rules at regional levels. Consequently, human pressures on sharks are partially explained through social marginalization that legitimizes permissive international rules that: (1) have limited scope of authority, (2) provide little-to-no active management of sharks, (3) have important enforcement problems, and (4) are generally not reinforced with National Plans of Action demonstrating a lack of commitment at both national and international scales. Thus, active management of shark populations is nearly non-existent meanwhile pressures on sharks, such as through finning, have increased in the last 20 years and there is strong evidence that many shark species are in decline and may not be able to recover. This paper concludes by arguing that biological oceanography of sharks is fundamentally linked to human dimensions, and, therefore, theories and systematic study of human dimensions in oceanography are crucial to provide more comprehensive understanding of complete social-marine systems.

The geological and geophysical complexities in Indian ocean basin, pointed out by many earlier workers remained unresolved. Instead, taking aid from stop gap arguments, the data has been construed to follow plate tectonics format. The concept of large igneous complexes emplaced through crustal drifting ( between the India and Mozambique) during later Mesozoic to Recent fail to address geophysical characteristics exhibited here. The geophysical signatures of the sub crustal part of the ocean here resemble to that of continental regions elsewhere. Granites, greenstones and mylonized gabbro, recovered from the western Indian ocean basin, rather give Late Pre- Cambrian and Paleozoic isotopic dates. Under this light, the present paper looks into the ocean bottom characteristics of a region between iles Rodrigues and Chagos- Maldives archipelago. The region has first order curvilienar fractures, with along which the crust has displaced more than 1000m. The sea-bottom topography of the region has been modeled in Geographical Information System environment using Modified ETOPO5 provided by National Institute of Oceanography. The spatial relationship of topography with gravity and magnetic data area are analysed visually and mathematically. The detail bathymetry, gravity and magnetic data give morphology similar to that of half graben formed on a felsic crust, which later has undergone basification / eclogitization through first order fracture zones.

Floods, hurricanes, and longer-term changes in climate and land use can have profound effects on water quality due to shifts in hydrologic flow paths, water residence time, precipitation patterns, connectivity between rivers and uplands, and many other factors. In order to understand and respond to changes in hydrology and water quality, resource managers and policy makers have a need for accurate and early indicators, as well as the ability to assess possible mechanisms and likely outcomes. In-situ optical sensors-those making continuous measurements of constituents by absorbance or fluorescence properties in the environment at timescales of minutes to years-have a long history in oceanography for developing highly resolved concentrations and fluxes, but are not commonly used in freshwater systems. The United States Geological Survey (USGS) has developed the Aquatic Real-Time Monitoring Network, with high-resolution optical data collection for organic carbon, nutrients, and sediment in large coastal rivers, along with continuous measurements of discharge, water temperature, and dissolved inorganic carbon. The collecting of continuous water-quality data in the Nation?s waterways has revealed temporal trends and spatial patterns in constituents that traditional sampling approaches fail to capture, and will serve a critical role in monitoring, assessment and decision-making in a rapidly changing landscape.

Roger Hayward and the Invention of the Two-Mirror Schmidt

Roger Hayward (1899-1979), now virtually unknown, was a multitalented architect, scientific illustrator, and optical inventor. Remembered primarily for illustrating Scientific American magazine's Amateur Scientist column between 1949 and 1974, he also illustrated more than a dozen textbooks in optics, physics, geology, oceanography, and chemistry, several of which became classics in their fields. He designed façades with astronomical themes for major buildings in Los Angeles, California, and sculpted mammoth, realistic models of the moon for Griffith Observatory, Adler Planetarium, and Disneyland. Throughout his life, he recreationally painted watercolors and oils that at least one critic likened to the work of John Singer Sargent. Hayward is least known as an optical designer, yet he made significant contributions to the DU spectrophotometer that established the multimillion-dollar company Beckman Instruments. During the pre-radar days of World War II at Mount Wilson Observatory, Hayward invented a classified Cassegrain version of the Schmidt telescope especially adapted for nighttime infrared aerial photography, plus extraordinarily simple machines that allowed inexperienced soldiers to grind, polish, and test accurate aspheric Schmidt correcting plates at speeds compatible with mass production - and later received U.S. patents for them all. This paper, drawn in part from unpublished letters between Hayward and Albert G. Ingalls, will feature little-known images of Hayward's work.

Currently available database technology is largely designed for business data-processing applications, and seems inadequate for scientific applications. The research described in this paper, the DataHub, will address the issues associated with this shortfall in technology utilization and development. The DataHub development is addressing the key issues in scientific data management of scientific database models and resource sharing in a geographically distributed, multi-disciplinary, science research environment. Thus, the DataHub will be a server between the data suppliers and data consumers to facilitate data exchanges, to assist science data analysis, and to provide as systematic approach for science data management. More specifically, the DataHub's objectives are to provide support for (1) exploratory data analysis (i.e., data driven analysis); (2) data transformations; (3) data semantics capture and usage; analysis-related knowledge capture and usage; and (5) data discovery, ingestion, and extraction. Applying technologies that vary from deductive databases, semantic data models, data discovery, knowledge representation and inferencing, exploratory data analysis techniques and modern man-machine interfaces, DataHub will provide a prototype, integrated environement to support research scientists' needs in multiple disciplines (i.e. oceanography, geology, and atmospheric) while addressing the more general science data management issues. Additionally, the DataHub will provide data management services to exploratory data analysis applications such as LinkWinds and NCSA's XIMAGE.

NASA's Earth Observatory (EO) is a 13-year old online publication focusing on the communication of NASA Earth science research, including climate change, weather, geology, oceanography, and solar flares. We serve two primary audiences: the "attentive public"--people interested in and willing to seek out information about science, technology, and the environment--and popular media. We use the EO website (earthobservatory.nasa.gov) to host a variety of content including image-driven stories (natural events and research-based), articles featuring NASA research and, more recently, blogs that give us the ability to increase interaction with our users. For much of our site's history, our communication has been largely one way, and we have relied primarily on traditional online marketing techniques such as RSS and email listservs. As the information ecosystem evolves into one in which many users expect to play a more active role in distributing and even developing content through social media, we've experimented with various social media outlets (blogs, Twitter, Facebook, Google+, etc.) that offer new opportunities for people to interact with NASA data, scientists, and the EO editorial team. As part of our explorations, we are learning about how, and to what extent, these outlets can be used for interaction and outright promotion and how to achieve those goals with existing personnel and resources.

Moore, C.

2011-12-01

The Index to Marine and Lacustrine Geological Samples is a community designed and maintained resource enabling researchers to locate and request sea floor and lakebed geologic samples archived by partner institutions. Conceived in the dawn of the digital age by representatives from U.S. academic and government marine core repositories and the NOAA National Geophysical Data Center (NGDC) at a 1977 meeting convened by the National Science Foundation (NSF), the Index is based on core concepts of community oversight, common vocabularies, consistent metadata and a shared interface. Form and content of underlying vocabularies and metadata continue to evolve according to the needs of the community, as do supporting technologies and access methodologies. The Curators Consortium, now international in scope, meets at partner institutions biennially to share ideas and discuss best practices. NGDC serves the group by providing database access and maintenance, a list server, digitizing support and long-term archival of sample metadata, data and imagery. Over three decades, participating curators have performed the herculean task of creating and contributing metadata for over 195,000 sea floor and lakebed cores, grabs, and dredges archived in their collections. Some partners use the Index for primary web access to their collections while others use it to increase exposure of more in-depth institutional systems. The Index is currently a geospatially-enabled relational database, publicly accessible via Web Feature and Web Map Services, and text- and ArcGIS map-based web interfaces. To provide as much knowledge as possible about each sample, the Index includes curatorial contact information and links to related data, information and images; 1) at participating institutions, 2) in the NGDC archive, and 3) at sites such as the Rolling Deck to Repository (R2R) and the System for Earth Sample Registration (SESAR). Over 34,000 International GeoSample Numbers (IGSNs) linking to SESAR are included in anticipation of opportunities for interconnectivity with Integrated Earth Data Applications (IEDA) systems. To promote interoperability and broaden exposure via the semantic web, NGDC is publishing lithologic classification schemes and terminology used in the Index as Simple Knowledge Organization System (SKOS) vocabularies, coordinating with R2R and the Consortium for Ocean Leadership for consistency. Availability in SKOS form will also facilitate use of the vocabularies in International Standards Organization (ISO) 19115-2 compliant metadata records. NGDC provides stewardship for the Index on behalf of U.S. repositories as the NSF designated "appropriate National Data Center" for data and metadata pertaining to sea floor samples as specified in the 2011 Division of Ocean Sciences Sample and Data Policy, and on behalf of international partners via a collocated World Data Center. NGDC operates on the Open Archival Information System (OAIS) reference model. Active Partners: Antarctic Marine Geology Research Facility, Florida State University; British Ocean Sediment Core Research Facility; Geological Survey of Canada; Integrated Ocean Drilling Program; Lamont-Doherty Earth Observatory; National Lacustrine Core Repository, University of Minnesota; Oregon State University; Scripps Institution of Oceanography; University of Rhode Island; U.S. Geological Survey; Woods Hole Oceanographic Institution.

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.

SeaDataNet II - EMODNet - building a pan-European infrastructure for marine and ocean data management

NASA Astrophysics Data System (ADS)

Schaap, Dick M. A.; Fichaut, Michele

2014-05-01

The second phase of the project SeaDataNet is well underway since October 2011 and is making good progress. The main objective is to improve operations and to progress towards an efficient data management infrastructure able to handle the diversity and large volume of data collected via research cruises and monitoring activities in European marine waters and global oceans. The SeaDataNet infrastructure comprises a network of interconnected data centres and a central SeaDataNet portal. The portal provides users a unified and transparent overview of the metadata and controlled access to the large collections of data sets, managed by the interconnected data centres, and the various SeaDataNet standards and tools,. Recently the 1st Innovation Cycle has been completed, including upgrading of the CDI Data Discovery and Access service to ISO 19139 and making it fully INSPIRE compliant. The extensive SeaDataNet Vocabularies have been upgraded too and implemented for all SeaDataNet European metadata directories. SeaDataNet is setting and governing marine data standards, and exploring and establishing interoperability solutions to connect to other e-infrastructures on the basis of standards of ISO (19115, 19139), OGC (WMS, WFS, CS-W and SWE), and OpenSearch. The population of directories has also increased considerably in cooperation and involvement in associated EU projects and initiatives. SeaDataNet now gives overview and access to more than 1.4 million data sets for physical oceanography, chemistry, geology, geophysics, bathymetry and biology from more than 90 connected data centres from 30 countries riparian to European seas. Access to marine data is also a key issue for the implementation of the EU Marine Strategy Framework Directive (MSFD). The EU communication 'Marine Knowledge 2020' underpins the importance of data availability and harmonising access to marine data from different sources. SeaDataNet qualified itself for leading the data management component of the EMODNet (European Marine Observation and Data Network) that is promoted in the EU Communication. In the past 4 years EMODNet portals have been initiated for marine data themes: digital bathymetry, chemistry, physical oceanography, geology, biology, and seabed habitat mapping. These portals are now being expanded to all European seas in successor projects, which started mid 2013 from EU DG MARE. EMODNet encourages more data providers to come forward for data sharing and participating in the process of making complete overviews and homogeneous data products. The EMODNet Bathymetry project is very illustrative for the synergy with SeaDataNet and added value of generating public data products. The project develops and publishes Digital Terrain Models (DTM) for the European seas. These are produced from survey and aggregated data sets. The portal provides a versatile DTM viewing service with many relevant map layers and functions for retrieving. A further refinement is taking place in the new phase. The presentation will give information on present services of the SeaDataNet infrastructure and services, highlight key achievements in SeaDataNet II so far, and give further insights in the EMODNet Bathymetry progress.

Effective, Active Learning Strategies for the Oceanography Classroom

NASA Astrophysics Data System (ADS)

Dmochowski, J. E.; Marinov, I.

2014-12-01

A decline in enrollment in STEM fields at the university level has prompted extensive research on alternative ways of teaching and learning science. Inquiry-based learning as well as the related "flipped" or "active" lectures, and similar teaching methods and philosophies have been proposed as more effective ways to disseminate knowledge in science classes than the traditional lecture. We will provide a synopsis of our experiences in implementing some of these practices into our Introductory Oceanography, Global Climate Change, and Ocean Atmosphere Dynamics undergraduate courses at the University of Pennsylvania, with both smaller and larger enrollments. By implementing tools such as at-home modules; computer labs; incorporation of current research; pre- and post-lecture quizzes; reflective, qualitative writing assignments; peer review; and a variety of in-class learning strategies, we aim to increase the science literacy of the student population and help students gain a more comprehensive knowledge of the topic, enhance their critical thinking skills, and correct misconceptions. While implementing these teaching techniques with college students is not without complications, we argue that a blended class that flexibly and creatively accounts for class size and science level improves the learning experience and the acquired knowledge. We will present examples of student assignments and activities as well as describe the lessons we have learned, and propose ideas for moving forward to best utilize innovative teaching tools in order to increase science literacy in oceanography and other climate-related courses.

The Indigo V Indian Ocean Expedition: a prototype for citizen microbial oceanography

Microbial Oceanography has long been an extremely expensive discipline, requiring ship time for sample collection and thereby economically constraining the number of samples collected. This is especially true for under-sampled water bodies such as the Indian Ocean. Specialised scientific equipment only adds to the costs. Moreover, long term monitoring of microbial communities and large scale modelling of global biogeochemical cycles requires the collection of high-density data both temporally and spatially in a cost-effective way. Thousands of private ocean-going vessels are cruising around the world's oceans every day. We believe that a combination of new technologies, appropriate laboratory protocols and strategic operational partnerships will allow researchers to broaden the scope of participation in basic oceanographic research. This will be achieved by equipping sailing vessels with small, satcom-equipped sampling devices, user-friendly collection techniques and a 'pre-addressed-stamped-envelope' to send in the samples for analysis. We aim to prove that 'bigger' is not necessarily 'better' and the key to greater understanding of the world's oceans is to forge the way to easier and cheaper sample acquisition. The ultimate goal of the Indigo V Expedition is to create a working blue-print for 'citizen microbial oceanography'. We will present the preliminary outcomes of the first Indigo V expedition, from Capetown to Singapore, highlighting the challenges and opportunities of such endeavours.

As part of the Barrier Island Monitoring Project, scientists from the U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center conducted nearshore geophysical surveys off Breton and Gosier Islands, Louisiana, in July and August of 2014. To assist the United States Fish and Wildlife Service (USFWS) with restoration planning efforts, the USGS was tasked with answering fundamental questions about the physical environment of the southern Chandeleur Islands, including the geology, morphology, and oceanography. Baseline data needed to answer these questions were either insufficient or missing. The USGS conducted a comprehensive geologic investigation in the summer of 2014, collecting geophysical and sedimentological data.Breton Island, located at the southern end of the Chandeleur Island chain in southeastern Louisiana, was recognized as a natural, globally significant nesting sanctuary for several bird species and was established as the Breton National Wildlife Refuge (NWR) in 1904. The areal extent of Breton Island has diminished 90 percent since 1920. Land loss is attributed to ongoing relative sea-level rise, diminished sediment supply, and storm impacts. The bird population on Breton Island has also declined over the years, most notably after Hurricane George in 1998 and after Hurricane Katrina in 2015; the latter completely submerged the island. Despite decreasing habitable acreage, migratory seabirds continue to return and nest on Breton Island. To prevent the island from being submerged in the future, and to protect, stabilize, and provide more nesting and foraging areas for the bird population, the USFWS proposed a restoration effort to rebuild Breton Island to its pre-Katrina footprint.This data series serves as an archive of processed interferometric swath and single-beam bathymetry data, and side-scan sonar data, collected in the nearshore of Breton and Gosier Islands, NWR, Louisiana. The data were collected during two USGS cruises (USGS Field Activity Numbers 2014-314-FA and 2014-317-FA) in July and August 2014. Geographic information system data products include a 100-meter-cell-size interpolated bathymetry grid, trackline maps, and point data files. Additional files include error analysis maps, Field Activity Collection System logs, and formal Federal Geographic Data Committee metadata.NOTE: These data are scientific in nature and are not to be used for navigation.

The subduction of oceanic lithosphere beneath convergent plate margins is a fundamental plate tectonic concept and an important Earth process. It is responsible for some of Earth's most dangerous natural hazards including earthquakes and volcanic eruptions but also produced the continental crust and important mineral deposits. A range of geoscientific efforts including NSF MARGINS and GeoPRISMS initiatives have advanced our understanding of subduction zone processes. In spite the importance of subduction zones and our advancing understanding of how these function, there are few animations that clearly explain the subduction process to non-expert audiences. This deficiency reflects the disparate expertises between geoscientists who know the science but have weak animation skills and digital artists and animators who have strong skills in showing objects in motion but are not experts in natural processes like plate tectonics. This transdisciplinary gap can and should be bridged. With a small grant from NSF (DUE-1444954) we set about to generate a realistic subduction zone animation aimed at the university undergraduate audience by first working within our university to rough out a draft animation and then contract a professional to use this to construct the final version. UTD Geosciences faculty (Stern) and graduate student (Lieu) teamed up with faculty from UTD School of Arts, Technology, and Emerging Communication (ATEC)(Farrar, Fechter, and McComber) to identify and recruit talented ATEC undergraduate students (Mantey, Ward) to work on the project. Geoscientists assembled a storyboard and met weekly with ATEC undergraduates to generate a first draft of the animation, which guided development of an accompanying narrative. The draft animation with voice-over was then handed off to professional animator Windler (Archistration CG) to generate the final animation. We plan to show both the student-generated draft version and the final animation during our presentation. The final animation will be freely available via the internet and will also be used as a supplement for McGraw-Hill textbooks in oceanography, physical geology, Earth science, geography, historical geology, natural hazards, and natural resources.

Problems inherent in using aircraft for radio oceanography studies

NASA Technical Reports Server (NTRS)

Walsh, E. J.

1977-01-01

Some of the disadvantages relating to altitude stability and proximity to the ocean are described for radio oceanography studies using aircraft. The random oscillatory motion introduced by the autopilot in maintaining aircraft altitude requires a more sophisticated range tracker for a radar altimeter than would be required in a satellite application. One-dimensional simulations of the sea surface (long-crested waves) are performed using both the JONSWAP spectrum and the Pierson-Moskowitz spectrum. The results of the simulation indicate that care must be taken in trying to experimentally verify instrument measurement accuracy. Because of the relatively few wavelengths examined from an aircraft due to proximity to the ocean and low velocity compared to a satellite, the random variation in the sea surface parameters being measured can far exceed an instrument's ability to measure them.

Geomicrobiology in oceanography: microbe-mineral interactions at and below the seafloor.

PubMed

Edwards, Katrina J; Bach, Wolfgang; McCollom, Thomas M

2005-09-01

Oceanography is inherently interdisciplinary and, since its inception, has included the study of microbe-mineral interactions. From early studies of manganese nodules, to the discovery of hydrothermal vents, it has been recognized that microorganisms are involved at various levels in the transformation of rocks and minerals at and below the seafloor. Recent studies include mineral weathering at low temperatures and microbe-mineral interactions in the subseafloor "deep biosphere". A common characteristic of seafloor and subseafloor geomicrobiological processes that distinguishes them from terrestrial or near-surface processes is that they occur in the dark, one or more steps removed from the sunlight that fuels the near-surface biosphere on Earth. This review focuses on geomicrobiological studies and energy flow in dark, deep-ocean and subseafloor rock habitats.

Virophages to viromes: a report from the frontier of viral oceanography.

Culley, Alexander I

2011-07-01

The investigation of marine viruses has advanced our understanding of ecology, evolution, microbiology, oceanography and virology. Significant findings discussed in this review include the discovery of giant viruses that have genome sizes and metabolic capabilities that distort the line between virus and cell, viruses that participate in photosynthesis and apoptosis, the detection of communities of viruses of all genomic compositions and the preeminence of viruses in the evolution of marine microbes. Although we have made great progress, we have yet to synthesize the rich archive of viral genomic data with oceanographic processes. The development of cutting edge methods such as single virus genomics now provide a toolset to better integrate viruses into the ecology of the ocean. Copyright © 2011 Elsevier B.V.

2007-10-01

In July 2006, the North Pacific Marine Science Organization (PICES) and Fisheries & Oceans Canada sponsored the symposium “Time Series of the Northeast Pacific: A symposium to mark the 50th anniversary of Line P”. The symposium, which celebrated 50 years of oceanography along Line P and at Ocean Station Papa (OSP), explored the scientific value of the Line P and other long oceanographic time series of the northeast Pacific (NEP). Overviews of the principal NEP time-series were presented, which facilitated regional comparisons and promoted interaction and exchange of information among investigators working in the NEP. More than 80 scientists from 8 countries attended the symposium. This introductory essay is a brief overview of the symposium and the 10 papers that were selected for this special issue of Progress in Oceanography.

In the Footsteps of Roger Revelle: A STEM Partnership Between Scripps Institution of Oceanography, Office of Naval Research and Middle School Science Students Bringing Next Generation Science Standards into the Classroom through Ocean Science

NASA Astrophysics Data System (ADS)

Brice, D.; Appelgate, B., Jr.; Mauricio, P.

2014-12-01

Now in its tenth year, "In the Footsteps of Roger Revelle" (IFRR) is a middle school science education program that draws student interest, scientific content and coherence with Next Generation Science Standards from real-time research at sea in fields of physical science. As a successful collaboration involving Scripps Institution of Oceanography (SIO),Office of Naval Research (ONR), and San Marcos Middle School (SMMS), IFRR brings physical oceanography and related sciences to students at the San Marcos Middle School in real-time from research vessels at sea using SIO's HiSeasNet satellite communication system. With a generous grant from ONR, students are able to tour the SIO Ships and spend a day at sea doing real oceanographic data collection and labs. Through real-time and near-realtime broadcasts and webcasts, students are able to share data with scientists and gain an appreciation for the value of Biogeochemical research in the field as it relates to their classroom studies. Interaction with scientists and researchers as well as crew members gives students insights into not only possible career paths, but the vital importance of cutting edge oceanographic research on our society. With their science teacher on the ship as an education outreach specialist or ashore guiding students in their interactions with selected scientists at sea, students observe shipboard research being carried out live via videoconference, Skype, daily e-mails, interviews, digital whiteboard sessions, and web interaction. Students then research, design, develop, deploy, and field-test their own data-collecting physical oceanography instruments in their classroom. The online interactive curriculum models the Next Generation Science Standards encouraging active inquiry and critical thinking with intellectually stimulating problem- solving, enabling students to gain critical insight and skill while investigating some of the most provocative questions of our time, and seeing scientists as role-models. IFRR has provided students in the San Diego area with a unique opportunity for learning about oceanographic research, which could inspire students to become oceanographers or at least scientifically literate citizens, a benefit for our society at large.

Developments in Airborne Oceanography and Air-Sea Interaction

NASA Astrophysics Data System (ADS)

Melville, W. K.

2014-12-01

One of the earliest ocean-related flights was that of Amundsen to be first across the North Pole and Arctic from Svalbard to Alaska in the airship Norge in 1926. Twenty five years later Cox & Munk flew a B-17G "Flying Fortress" bomber over Hawaiian waters measuring sea surface slope statistics from photographs of sun glitter and wind speed from a yacht. The value of Cox & Munk's "airborne oceanography" became apparent another twenty five years later with the short-lived Seasat microwave remote-sensing mission, since interpretation of the Seasat data in geophysical variables required scattering theories that relied on their data. The universal acceptance of remote sensing in oceanography began in 1992 with the launch of, and successful analysis of sea surface height data from, the Topex/Poseidon radar altimeter. With that and the development of more realistic coupled atmosphere-ocean models it became apparent that our understanding of weather and climate variability in both the atmosphere and the ocean depends crucially on our ability to measure processes in boundary layers spanning the interface. Ten years ago UNOLS formed the Scientific Committee for Oceanographic Aircraft Research (SCOAR) "...to improve access to research aircraft facilities for ocean sciences"; an attempt to make access to aircraft as easy as access to research vessels. SCOAR emphasized then that "Aircraft are ideal for both fast-response investigations and routine, long-term measurements, and they naturally combine atmospheric measurements with oceanographic measurements on similar temporal and spatial scales." Since then developments in GPS positioning and miniaturization have made scientific measurements possible from smaller and smaller platforms, including the transition from manned to unmanned aerial vehicles (UAVs). Furthermore, ship-launched and recovered UAVs have demonstrated how they can enhance the capabilities and reach of the research vessels, "projecting" research and science, just as aircraft carriers "project force". Now we can measure winds, waves, temperatures, currents, radiative transfer, images and air-sea fluxes from aircraft over the ocean.I will review some of the history of airborne oceanography and present examples of how it can extend our knowledge and understanding of air-sea interaction.

The role of ocean climate data in operational Naval oceanography

NASA Technical Reports Server (NTRS)

Chesbrough, Radm G.

1992-01-01

Local application of global-scale models describes the U.S. Navy's basic philosophy for operational oceanography in support of fleet operations. Real-time data, climatologies, coupled air/ocean models, and large scale computers are the essential components of the Navy's system for providing the war fighters with the performance predictions and tactical decision aids they need to operate safely and efficiently. In peacetime, these oceanographic predictions are important for safety of navigation and flight. The paucity and uneven distribution of real-time data mean we have to fall back on climatology to provide the basic data to operate our models. The Navy is both a producer and user of climatologies; it provides observations to the national archives and in turn employs data from these archives to establish data bases. Suggestions for future improvements to ocean climate data are offered.

Applications of the Coastal Zone Color Scanner in oceanography

NASA Technical Reports Server (NTRS)

Mcclain, C. R.

1988-01-01

Research activity has continued to be focused on the applications of the Coastal Zone Color Scanner (CZCS) imagery in oceanography. A number of regional studies were completed including investigations of temporal and spatial variability of phytoplankton populations in the South Atlantic Bight, Northwest Spain, Weddell Sea, Bering Sea, Caribbean Sea and in tropical Atlantic Ocean. In addition to the regional studies, much work was dedicated to developing ancillary global scale meteorological and hydrographic data sets to complement the global CZCS processing products. To accomplish this, SEAPAK's image analysis capability was complemented with an interface to GEMPAK (Severe Storm Branch's meteorological analysis software package) for the analysis and graphical display of gridded data fields. Plans are being made to develop a similar interface to SEAPAK for hydrographic data using EPIC (a hydrographic data analysis package developed by NOAA/PMEL).

A two-dimensional composite grid numerical model based on the reduced system for oceanography

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

Xie, Y.F.; Browning, G.L.; Chesshire, G.

The proper mathematical limit of a hyperbolic system with multiple time scales, the reduced system, is a system that contains no high-frequency motions and is well posed if suitable boundary conditions are chosen for the initial-boundary value problem. The composite grid method, a robust and efficient grid-generation technique that smoothly and accurately treats general irregular boundaries, is used to approximate the two-dimensional version of the reduced system for oceanography on irregular ocean basins. A change-of-variable technique that substantially increases the accuracy of the model and a method for efficiently solving the elliptic equation for the geopotential are discussed. Numerical resultsmore » are presented for circular and kidney-shaped basins by using a set of analytic solutions constructed in this paper.« less

2012-12-01

Project "Arctic Ocean sea ice and ocean circulation using satellite methods" (SATICE), is the first high-rate, high-precision, continuous GPS positioning experiment on sea ice in the Arctic Ocean. The SATICE systems collect continuous, dual-frequency carrier-phase GPS data while drifting on sea ice. Additional geophysical measurements also collected include ocean water pressure, ocean surface salinity, atmospheric pressure, snow-depth, air-ice-ocean temperature profiles, photographic imagery, and others, enabling sea ice drift, freeboard, weather, ice mass balance, and sea-level height determination. Relatively large volumes of data from each buoy are streamed over a satellite link to a central computer on the Internet in near real time, where they are processed to estimate the time-varying buoy positions. SATICE system obtains continuous GPS data at sub-minute intervals with a positioning precision of a few centimetres in all three dimensions. Although monitoring of sea ice motions goes back to the early days of satellite observations, these autonomous platforms bring out a level of spatio-temporal detail that has never been seen before, especially in the vertical axis. These high-resolution data allows us to address new polar science questions and challenge our present understanding of both sea ice dynamics and Arctic oceanography. We will describe the technology behind this new autonomous platform, which could also be adapted to other applications that require high resolution positioning information with sustained operations and observations in the polar marine environment, and present results pertaining to sea ice dynamics and physical oceanography.

Graphical methods and Cold War scientific practice: the Stommel Diagram's intriguing journey from the physical to the biological environmental sciences.

PubMed

Vance, Tiffany C; Doel, Ronald E

2010-01-01

In the last quarter of the twentieth century, an innovative three-dimensional graphical technique was introduced into biological oceanography and ecology, where it spread rapidly. Used to improve scientists' understanding of the importance of scale within oceanic ecosystems, this influential diagram addressed biological scales from phytoplankton to fish, physical scales from diurnal tides to ocean currents, and temporal scales from hours to ice ages. Yet the Stommel Diagram (named for physical oceanographer Henry Stommel, who created it in 1963) had not been devised to aid ecological investigations. Rather, Stommel intended it to help plan large-scale research programs in physical oceanography, particularly as Cold War research funding enabled a dramatic expansion of physical oceanography in the 1960s. Marine ecologists utilized the Stommel Diagram to enhance research on biological production in ocean environments, a key concern by the 1970s amid growing alarm about overfishing and ocean pollution. Before the end of the twentieth century, the diagram had become a significant tool within the discipline of ecology. Tracing the path that Stommel's graphical techniques traveled from the physical to the biological environmental sciences reveals a great deal about practices in these distinct research communities and their relative professional and institutional standings in the Cold War era. Crucial to appreciating the course of that path is an understanding of the divergent intellectual and social contexts of the physical versus the biological environmental sciences.

Physical oceanography of continental shelves

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

Allen, J.S.; Beardlsey, R.C.; Blanton, J.O.

Knowledge of the physical oceanography of continental shelves has increased tremendously in recent years, primarily as a result of new current and hydrographic measurements made in locations where no comparable measurements existed previously. In general, observations from geographically distinct continental shelves have shown that the nature of the flow may vary considerably from region to region. Although some characteristics, such as the response of currents to wind forcing, are common to many shelves, the relative importance of various physical processes in influencing the shelf flow field frequently is different. In the last several years, the scientific literature on shelf studiesmore » has expanded rapidly, with that for separate regions, to some extent, developing independently because of the variable role played by different physical effects. Consequently, it seems that a simultaneous review of progress in physical oceanographic research in different shelf regions would be especially useful at this time in order to help assess the overall progress in the field. This multi-author report has been compiled as a result. Included are sections on the physical oceanography of continental shelves, in or off of, the eastern Bering Sea, northern Gulf of Alaska, Pacific Northwest, southern California, west Florida, southeastern US, Middle Atlantic Bight, Georges Bank and Peru. These discussions clearly point to the diverse nature of the dominant physics in several of the regions, as well as to some of the dynamical features they share in common. 390 references, 23 figures.« less

Geophysical Fluid Dynamics Laboratory Open Days at the Woods Hole Oceanographic Institution

2015-11-01

This event was hosted for one week for two consecutive years in 2013 and 2014. It targeted postdocs, graduate students, K-12 students and local community participation. The Geophysical Fluid Dynamics Laboratory at the Woods Hole Oceanographic Institution hosted 10 hands-on demonstrations and displays, with something for all ages, to share the excitement of fluid mechanics and oceanography. The demonstrations/experiments spanned as many fluid mechanics problems as possible in all fields of oceanography and gave insight into using fluids laboratory experiments as a research tool. The chosen experiments were `simple' yet exciting for a 6 year old child, a high school student, a graduate student, and a postdoctoral fellow from different disciplines within oceanography. The laboratory is a perfect environment in which to create excitement and stimulate curiosity. Even what we consider `simple' experiments can fascinate and generate interesting questions from both a 6 year old child and a physics professor. How does an avalanche happen? How does a bath tub vortex form? What happens to waves when they break? How does a hurricane move? Hands-on activities in the fluid dynamics laboratory helped students of all ages in answering these and other intriguing questions. The laboratory experiments/demonstrations were accompanied by `live' videos to assist in the interpretation of the demonstrations. Posters illustrated the oceanographic/scientific applicability and the location on Earth where the dynamics in the experiments occur. Support was given by the WHOI Doherty Chair in Education.

Interdisciplinary research collaborations that address complex, global research themes such as the interactive effects of global warming and studies of pelagic food webs require access to a broad range of data types from all disciplines of oceanography, from all platforms (e.g. ships, gliders, floats, moorings), with the in situ observations complementing and being complemented by laboratory and model results. In an effort to build a comprehensive database of marine ecosystem research data, the National Science Foundation (NSF) funded the Biological and Chemical Oceanography Data Management Office (BCO-DMO; bco-dmo.org) to support the data management requirements of investigators funded by the NSF's Polar Programs (PLR) and Biological and Chemical Oceanography Sections (OCE). Since 2006, investigators funded by NSF PLR and OCE have been working with support from BCO-DMO data scientists, to build a data system that now includes the full range of ocean biogeochemistry data resulting from decades of research. In addition to data from recently funded PIs, the BCO-DMO data system also serves data from legacy programs (e.g. US Joint Global Ocean Flux Study and US Global Ocean Ecosystem Dynamics). The data are open-access, available for download in a variety of user-selectable formats, and accompanied by sufficient documentation to enable re-use. This presentation will highlight the diversity of data available from the BCO-DMO system and demonstrate some of the features that enable discovery, access and download of data relevant to studies of pelagic food webs.

The need for efficient and effective on line data management is greatly recognized today by the marine research community. The Cyprus Oceanography Center at the University of Cyprus, realizing this need, is continuously working in this area and has developed a variety of data management and visualization tools which are currently utilized for both the Mediterranean and the Black Sea. Bythos, CYCOFOS and LAS server are three different systems employed by the Oceanography Center, each one dealing with different data sets and processes. Bythos is a rich internet application that combines the latest technologies and enables scientists to search, visualize and download climatological oceanographic data with capabilities of being applied worldwide. CYCOFOS is an operational coastal ocean forecasting and observing system which provides in near real time predictions for sea currents, hydrological characteristics, waves, swells and tides, remote sensing and in-situ data from various remote observing platforms in the Mediterranean Sea, the EEZ and the coastal areas of Cyprus. LAS (Live Access Server) is deployed to present distributed various types of data sets as a unified virtual data base through the use of OpenDap networking. It is first applied for providing an integrated, high resolution system for monitoring the energy potential from sea waves in the Exclusive Economic Zone of Cyprus and the Eastern Mediterranean Levantine Basin. This paper presents the aforementioned technologies as currently adopted by the Cyprus Oceanography Center and describes their utilization that supports both the research and operational activities in the Mediterranean.

Constantino, R.; Dicelis, G.; Molina, E. C.

2010-12-01

This study aims to identify the tools available to disseminate the Earth sciences to young people in Brazil and to propose new techniques that may help in the teaching of such subjects. The use of scientific dissemination can be a great tool for the consolidation of a scientific culture, especially for a public of young students. The starting point of this study is an important characteristic that is present in virtually all the children: curiosity. The young public tries to understand how the world is and how it works. The use of scientific dissemination and some educational experiences have shown that these students have a great ability to learn and deal with various topics within the Earth Sciences. Another relevant point is the possibility to show that the Earth sciences, e.g., geophysics, oceanography, meteorology, geology and geography, can be an educational attractive option. Several ways of disseminating Earth sciences are commonly used with the purpose of attracting and mainly teaching these subjects, such as websites, interactive museums and cultural and educational spaces. The objectives of this work are: i) Investigate the role of science centers as motivators in disseminating the scientific knowledge by examining the communication resources that are being employed, the acceptance, reaction, and interest of children to these means, and ii) From this analysis, to list suggestions of contents and new tools that could be used for obtaining better results.

Leote, Catarina; Moura, Delminda; Azevedo Rodrigues, Luis

2017-04-01

Geoscience education is key for the understanding of our home, the planet Earth. The Lagos Ciência Viva Science Centre (CCVL) in Portugal develops various geoscience activities including astronomy sessions, geology, paleontology and oceanography field trips, complementary primary school classes, seminars and numerous workshops for a public ranging from pre-schoolers to seniors . Our experience in geoscience communication and informal education also includes a formal partnership with a research centre from the University of the Algarve, the CIMA - Centre for Marine and Environmental Research, through the project MOSES, which focuses on sand transport along crenulated coasts. Based on the project goals, methods and results, the CCVL team designed a communication and outreach plan including a seminar, a field trip and a workshop, to alert for the subjects of coastal erosion and management, both highly relevant in the Algarve. This partnership was highly beneficial for both parts as it facilitated the communication of a scientific project to the public, while the CCVL had the opportunity to update and expand its educational offer. This type of interaction between universities/research institutes and science centres/museums allows scientists to focus on their research work, reducing their need to invest in communication, and provides good and updated scientific contents to science communicators, ensuring a direct channel between scientific research and the public.

Welcome to NASA's Earth Science Enterprise: Educational CD-ROM Activity Supplement

NASA Technical Reports Server (NTRS)

1999-01-01

Since its inception in 1958, NASA has been studying the Earth and its changing environment by observing the atmosphere, oceans, land, ice, and snow, and their influence on weather and climate. We now understand that the key to gaining a better understanding of the global environment is exploring how the Earth's systems of air, land, water, and life interact with each other. This approach-called Earth Systems Science-blends together fields like meteorology, oceanography, geology, and biology. In 1991, NASA launched a more comprehensive program to study the Earth as an integrated environmental system. They call it NASA's Earth Science Enterprise. A major component of the Earth Science Enterprise is the Earth Observing System (EOS). EOS is series of satellites to be launched over the next two decades that will be used to intensively study the Earth, with the hopes of expanding our under- standing of how natural processes affect us, and how we might be affecting them. Such studies will yield improved weather forecasts, tools for managing agriculture and forests, information for fishermen and local planners, and, eventually, the ability to predict how the climate will change in the future. Today's program is laying the foundation for long-term environmental and climate monitoring and prediction. Potentially, this will provide the understanding needed in the future to support difficult decisions regarding the Earth's environment.

A recent shark radiation: molecular phylogeny, biogeography and speciation of wobbegong sharks (family: Orectolobidae).

PubMed

Corrigan, Shannon; Beheregaray, Luciano B

2009-07-01

The elasmobranch fish are an ancient, evolutionarily successful, but under-researched vertebrate group, particularly in regard to their recent evolutionary history. Their lineage has survived four mass extinction events and most present day taxa are thought to be derived from Mesozoic forms. Here we present a molecular phylogenetic analysis of the family Orectolobidae that provides evidence for recent events of diversification in this shark group. Species interrelationships in Orectolobidae were reconstructed based on four mitochondrial and nuclear genes. In line with previous morphological work, our results do not support current taxonomic arrangements in Orectolobidae and indicate that a taxonomic revision of the family is warranted. We propose that the onset of diversification of orectolobid sharks is of Miocene age and occurred within the Indo-Australian region. Surprisingly, we also find evidence for a recent ( approximately last 2 million years) and rapid radiation of wobbegong sharks. Allopatric speciation followed by range expansion seems like the general most likely explanation to account for wobbegong relationships and distributions. We suggest that the evolution of this shark group was mostly influenced by two temporal scenarios of diversification. The oldest relates to major geological changes in the Indo-West Pacific associated with the Miocene collision of the Indo-Australian and Eurasian plates. The most recent scenario was influenced by changes in oceanography and the emergence of biogeographic barriers related to Pleistocene glacial cycles in Australian waters.

Organic geochemistry - A retrospective of its first 70 years

USGS Publications Warehouse

Kvenvolden, K.A.

2006-01-01

Organic geochemistry had its origin in the early part of the 20th century when organic chemists and geologists realized that detailed information on the organic materials in sediments and rocks was scientifically interesting and of practical importance. The generally acknowledged "father" of organic geochemistry is Alfred E. Treibs (1899-1983), who discovered and described, in 1936, porphyrin pigments in shale, coal, and crude oil, and traced the source of these molecules to their biological precursors. Thus, the year 1936 marks the beginning of organic geochemistry. However, formal organization of organic geochemistry dates from 1959 when the Organic Geochemistry Division (OGD) of The Geochemical Society was founded in the United States, followed 22 years later (1981) by the establishment of the European Association of Organic Geochemists (EAOG). Organic geochemistry (1) has its own journal, Organic Geochemistry (beginning in 1979) which, since 1988, is the official journal of the EAOG, (2) convenes two major conferences [International Meeting on Organic Geochemistry (IMOG), since 1962, and Gordon Research Conferences on Organic Geochemistry (GRC), since 1968] in alternate years, and (3) is the subject matter of several textbooks. Organic geochemistry is now a widely recognized geoscience in which organic chemistry has contributed significantly not only to geology (i.e., petroleum geochemistry, molecular stratigraphy) and biology (i.e., biogeochemistry), but also to other disciplines, such as chemical oceanography, environmental science, hydrology, biochemical ecology, archaeology, and cosmochemistry.

Linking Ice Sheet Freshwater Discharge and Marine production in Greenland via Fiord Circulation. 'FreshLink', an Interdisciplinary Project Involving Researchers from Multiple Countries.

Bøggild, C. E.; Rysgaard, S.; Mortensen, J.; Kallenborn, R.; Truffer, M.; Forsberg, R.; Ahlstrøm, A. P.; Petersen, D.

2008-12-01

This interdisciplinary and international project has recently been initiated mainly with IPY funding from Denmark and Greenland. In short the project investigates the linkage between ice sheet freshwater release to a fiord near Nuuk (South-western Greenland) and the resulting fiord circulation. The low density melt water draining into the innermost of the long fiord forms a brackish outward sloping top layer, which exits the fiord and is balanced by entrance of nutritious salty oceanic water below. Such nutritious water, in turn, favors marine production in the fiord. The perspectives of a warmer climate, where more ice sheet melt water will increase the marine production, is of vital interest to investigate for the Greenland society because the present export from the country is totally dominated by living resources of the oceans. This interdisciplinary research project involves scientists from Greenland, Norway, Denmark and USA. Scientific disciplines presently covered are; marine ecology (biological production), cryospheric sciences (ice sheet and snow-water release), pollution chemistry (separating present from ancient precipitation), marine geology (history of freshwater input), oceanography (fiord circulation), geodesy (cryospheric elevation changes), and hydrology (land runoff). First field results will be presented together with the perspectives for linking each fresh water component coming from land and ice to the observed freshwater budget in the fiord.

Biological Oceanography

NASA Technical Reports Server (NTRS)

Abbott, M. R.

1984-01-01

Within the framework of global biogeochemical cycles and ocean productivity, there are two areas that will be of particular interest to biological oceanography in the 1990s. The first is the mapping in space time of the biomass and productivity of phytoplankton in the world ocean. The second area is the coupling of biological and physical processes as it affects the distribution and growth rate of phytoplankton biomass. Certainly other areas will be of interest to biological oceanographers, but these two areas are amenable to observations from satellites. Temporal and spatial variability is a regular feature of marine ecosystems. The temporal and spatial variability of phytoplankton biomass and productivity which is ubiquitous at all time and space scales in the ocean must be characterized. Remote sensing from satellites addresses these problems with global observations of mesocale (2 to 20 days, 10 to 200 km) features over a long period of time.

Seeing the oceans in the shadow of Bergen values.

PubMed

Hamblin, Jacob Darwin

2014-06-01

Although oceanographers such as Roger Revelle are typically associated with key indicators of anthropogenic change, he and other scientists at midcentury had very different scientific priorities and ways of seeing the oceans. How can we join the narrative of the triumph of mathematical, dynamic oceanography with the environmental narrative? Dynamic methods entailed a broad set of values that touched the professional lives of marine scientists in a variety of disciplines all over the world, for better or for worse. The present essay highlights three aspects of "Bergen values" in need of greater exploration by scholars. First, how did the dominance of Scandinavian outlooks influence scientific questions across the broad spectrum of oceanography? Second, did oceanographers' particular means of making the oceans legible through instrumentation challenge their ability to perceive the oceans differently? Third, given the immense quantity of data, was the historical legacy of the dynamic oceanographers more descriptive than they imagined?

NASA Astrophysics Data System (ADS)

In anticipation of the start (in Fiscal Year 1988) of a new Office of Naval Research (ONR) Accelerated Research Initiative (ARI) on Ocean Surface Wave Dynamics, a workshop was held August 5-7, 1986, at Woods Hole, Mass., to discuss new ideas and directions of research. This new ARI on Ocean Surface Wave Dynamics is a 5-year effort that is organized by the ONR Physical Oceanography Program in cooperation with the ONR Fluid Mechanics Program and the Physical Oceanography Branch at the Naval Ocean Research and Development Activity (NORDA). The central theme is improvement of our understanding of the basic physics and dynamics of surface wave phenomena, with emphasis on the following areas: precise air-sea coupling mechanisms,dynamics of nonlinear wave-wave interaction under realistic environmental conditions,wave breaking and dissipation of energy,interaction between surface waves and upper ocean boundary layer dynamics, andsurface statistical and boundary layer coherent structures.

The Equations of Oceanic Motions

NASA Astrophysics Data System (ADS)

Müller, Peter

2006-10-01

Modeling and prediction of oceanographic phenomena and climate is based on the integration of dynamic equations. The Equations of Oceanic Motions derives and systematically classifies the most common dynamic equations used in physical oceanography, from large scale thermohaline circulations to those governing small scale motions and turbulence. After establishing the basic dynamical equations that describe all oceanic motions, M|ller then derives approximate equations, emphasizing the assumptions made and physical processes eliminated. He distinguishes between geometric, thermodynamic and dynamic approximations and between the acoustic, gravity, vortical and temperature-salinity modes of motion. Basic concepts and formulae of equilibrium thermodynamics, vector and tensor calculus, curvilinear coordinate systems, and the kinematics of fluid motion and wave propagation are covered in appendices. Providing the basic theoretical background for graduate students and researchers of physical oceanography and climate science, this book will serve as both a comprehensive text and an essential reference.

Southern Ocean Iron Experiment (SOFex)

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

Coale, Kenneth H.

The Southern Ocean Iron Experiment (SOFeX) was an experiment decades in the planning. It's implementation was among the most complex ship operations that SIO has been involved in. The SOFeX field expedition was successful in creating and tracking two experimentally enriched areas of the Southern Ocean, one characterized by low silicic acid, one characterized by high silicic acid. Both experimental sites were replete with abundant nitrate. About 100 scientists were involved overall. The major findings of this study were significant in several ways: (1) The productivity of the southern ocean is limited by iron availability. (2) Carbon uptake and fluxmore » is therefore controlled by iron availability (3) In spite of low silicic acid, iron promotes non-silicious phytoplankton growth and the uptake of carbon dioxide. (4) The transport of fixed carbon from the surface layers proceeds with a C:N ratio that would indicate differential remineralization of nitrogen at shallow depths. (5) These finding have major implications for modeling of carbon export based on nitrate utilization. (6) The general results of the experiment indicate that, beyond other southern ocean enrichment experiments, iron inputs have a much wider impact of productivity and carbon cycling than previously demonstrated.

Benveniste, Jérôme; Knudsen, Per

2016-07-01

The GOCE User Toolbox GUT is a compilation of tools for the utilisation and analysis of GOCE Level 2 products. GUT support applications in Geodesy, Oceanography and Solid Earth Physics. The GUT Tutorial provides information and guidance in how to use the toolbox for a variety of applications. GUT consists of a series of advanced computer routines that carry out the required computations. It may be used on Windows PCs, UNIX/Linux Workstations, and Mac. The toolbox is supported by The GUT Algorithm Description and User Guide and The GUT Install Guide. A set of a-priori data and models are made available as well. Without any doubt the development of the GOCE user toolbox have played a major role in paving the way to successful use of the GOCE data for oceanography. The GUT version 2.2 was released in April 2014 and beside some bug-fixes it adds the capability for the computation of Simple Bouguer Anomaly (Solid-Earth). During this fall a new GUT version 3 has been released. GUTv3 was further developed through a collaborative effort where the scientific communities participate aiming on an implementation of remaining functionalities facilitating a wider span of research in the fields of Geodesy, Oceanography and Solid earth studies. Accordingly, the GUT version 3 has: - An attractive and easy to use Graphic User Interface (GUI) for the toolbox, - Enhance the toolbox with some further software functionalities such as to facilitate the use of gradients, anisotropic diffusive filtering and computation of Bouguer and isostatic gravity anomalies. - An associated GUT VCM tool for analyzing the GOCE variance covariance matrices.

Satellite observations of the ice cover of the Kuril Basin Region of the Okhotsk Sea and its relation to the regional oceanography

NASA Astrophysics Data System (ADS)

Wakatsuchi, Masaaki; Martin, Seelye

1990-08-01

For the period 1978-1982, this paper examines the nature of the sea ice which forms over the Kuril Basin of the Okhotsk Sea and describes the impact of this ice on the regional oceanography. The paper compares the oceanographic behavior during the heavy ice season associated with the cold 1979 winter with the behavior during the lighter ice years of 1980 and 1982. Examination of the oceanography in the Okhotsk and the adjacent Pacific shows that the early summer water column structure depends on the heat loss from the Okhotsk during the preceding ice season, the total amount of Okhotsk ice formation, and specifically the amount of ice formation in the Kuril Basin. Following the 1979 ice season, the upper 200-300 m of the Kuril Basin waters were cooler, less saline, and richer in oxygen than for the other years. This modification appears to be a process local to the Kuril Basin, driven by eddy-induced mixing, local cooling, and ice melting. In the depths 300-1200 m, the water modification is caused by the advection of water from the northern Okhotsk. For 1979, this deeper water is also less saline, colder, and richer in oxygen than for the lighter ice years. The water modified in the Okhotsk enters the adjacent North Pacific through the Bussol' Strait, where for 1979 the adjacent waters are also cooler, less saline, and richer in oxygen down to a depth of 1000 m than for the lighter ice years.

Science and Security before the Atomic Bomb: The Loyalty Case of Harald U. Sverdrup

NASA Astrophysics Data System (ADS)

Oreskes, Naomi; Rainger, Ronald

In the summer of 1941, Harald Sverdrup, the Norwegian-born Director of the Scripps Institution of Oceanography (SIO) in La Jolla, California, was denied security clearance to work on Navy-sponsored research in underwater acoustics applied to anti-submarine warfare. The clearance denial embarrassed the world renown oceanographer and Arctic explorer, who repeatedly offered his services to the U.S. government only to see scientists of far lesser reputation called upon to aid the war effort. The official story of Sverdrup's denial was the risk of blackmail over relatives in occupied Norway. Declassified documents tell a different story. Although Sverdrup's integrity was defended on the highest levels of U.S. science, doubt was cast upon him by members of his own institution, who accused him of being a Nazi sympathiser. Personal distrust, rooted in scientific and intellectual disagreement, spilled over into questions about Sverdrup's loyalty and judgement. These doubts were considered sufficient grounds for withholding clearance, until Roger Revelle, a former student of Sverdrup now working within the Navy, was able to obtain a limited clearance for Sverdrup to develop techniques to forecast surf conditions during amphibious assaults. After the war, this work was credited with saving many lives, but at the time it placed Sverdrup out of the mainstream of Navy-sponsored oceanographic research. In being denied access to major areas of scientific work, Sverdrup's position as a leader of American oceanography was undermined. The loyalty case of Harald Sverdrup illustrates the emergence of an institutional apparatus through which the U.S. military began to control and shape the organisation of American science in the twentieth century. Military sponsorship of scientific research, begun during the open conflicts of World War II and continuing into the simmering tensions of the Cold War, involved explicit control by the U.S. military of who had access to critical information. This in turn meant who could do science in conjunction with the military. As the U.S. Navy became the principal sponsor of oceanography in the post-war years, clearance to do military work became to a great extent clearance to do oceanography. Choices about who could be trusted were also choices about who would do science, and what kind of science they would do.

The Quest for the Africa-Eurasia plate boundary West of the Strait of Gibraltar

NASA Astrophysics Data System (ADS)

Zitellini, N.

2009-04-01

A new swath bathymetry compilation of the Gulf of Cadiz Area and SW Iberia is presented. The new map is the result of a collaborative research performed after year 2000 by teams from 7 European countries and 14 research institutions. This new dataset allow for the first time to present and to discuss the missing link in the plate boundary between Eurasia and Africa in the Central Atlantic. A set of almost linear and sub parallel dextral strike-slip faults, the SWIM Faults (SWIM is the acronym of the ESF EuroMargins project "Earthquake and Tsunami hazards of active faults at the South West Iberian Margin: deep structure, high-resolution imaging and paleoseismic signature") was mapped using a the new swath bathymetry compilation available in the area. The SWIM Faults form a narrow band of deformation over a length of 600 km coincident with a small circle centred on the pole of rotation of Africa with respect to Eurasia, This narrow band of deformation connects the Gloria Fault to the Rif-Tell Fault Zone, two segments of the plate boundary between Africa and Eurasia. In addition, the SWIM faults cuts across the Gulf of Cadiz, in the Atlantic Ocean, where the 1755 Great Lisbon earthquake, M~8.5-8.7, and tsunami were generated, providing a new insights on its source location.

A Global Study of Swath Bathymetry and the Changing Depth of the Seafloor with Time

NASA Astrophysics Data System (ADS)

Robinson, A. H.; Watts, A. B.; Paulatto, M.

2013-12-01

Morphological evidence from bathymetric surveying shows that the seafloor is subject to the same active tectonic and geological processes as the subaerial domain e.g. faulting, mass transport/debris flows, magmatic construction. Observing such processes in the submarine environment is difficult due to the inability to map at high-resolution using satellite methods. The open-access databases of swath bathymetry data - Marine Geoscience Data System (Lamont-Doherty Earth Observatory), SIOExplorer (Scripps Institute of Oceanography), GeoMapApp - are a valuable resource which has the potential to identify the presence, timing, and magnitude of submarine active geological processes through the use of repeat surveys. A dataset of 785 cruises between 1980-2009 was constructed from these sources. The global ocean was divided into ~35 regions based on potential for abundant ship-track crossings. Differences were calculated by gridding data for each region on a year-by-year basis and then subtracting between pairs of grids using the GMT software package. The resultant difference grids were inspected for features that could be robustly attributed to geological processes. At least 100 crossings appearing to show potential differences were investigated. We find evidence for both constructional (Vailulu'u seamount, Samoa; an unnamed seamount offshore Costa Rica; Axial Seamount, East Pacific Rise) and mass-wasting events (Rangi Seamount Chain, off-axis East Pacific Rise ~17S) for which the associated mass fluxes are quantifiable with magnitudes above the RMS difference between two surveys, typically up to 10m for unedited cruises downloaded directly from the online databases. For incidences of growth, volumetric rates appear concordant with results from previous works, and their magnitude (0.001-1km3/yr) suggests that they represent short-term magmatic fluxes. Rates of mass wasting are not comparable in the same way, since they represent effectively instantaneous events. Instead, it may be possible to produce size-frequency distributions through time for a number of events to determine if any patterns exist. Whilst designed to be encompassing of all geological/tectonic environments within the oceans the results of this study have been limited, with robust differences thus far restricted to seamounts. The abundance of data available would suggest that there is potential for further examples, and there is no reason why these should not appear in other tectonic settings, including along the mid-ocean ridge system and around bend faults on the outer rises of subduction zones. However, questions remain regarding the completeness and quality of processing of holdings within the databases that have been used. Further work should first focus on improving the quality and completeness of the global swath bathymetry database, thus it may be desirable to engage with data users, owners and managers to better understand how these data holdings can be used more effectively for large-scale (global) applications.

Using a dynamic, introductory-level volcanoes class as a means to introduce non-science majors to the geosciences

NASA Astrophysics Data System (ADS)

Cook, G. W.

2012-12-01

At the University of California, San Diego, I teach a quarter-long, introductory Earth Science class titled "Volcanoes," which is, in essence, a functional class in volcanology designed specifically for non-majors. This large-format (enrollment ~ 85), lecture-based class provides students from an assortment of backgrounds an opportunity to acquire much-needed (and sometimes dreaded) area credits in science, while also serving as an introduction to the Earth Science major at UCSD (offered through Scripps Institution of Oceanography). The overall goal of the course is to provide students with a stimulating and exciting general science option that, using an inherently interesting topic, introduces them to the fundamentals of geoscience. A secondary goal is to promote general science and geoscience literacy among the general population of UCSD. Student evaluations of this course unequivocally indicate a high degree of learning and interest in the material. The majority of students in the class (>80%) are non-science majors and very few students (<3%) are Earth science degree-seeking students. In addition, only a handful of students have typically had any form of geology class beyond high school level Earth Science. Consequently, there are challenges associated with teaching the class. Perhaps most significantly, students have very little background—background that is necessary for understanding the processes involved in volcanic eruptions. Second, many non-science students have built-in anxieties with respect to math and science, anxieties that must be considered when designing curriculum and syllabi. It is essential to provide the right balance of technical information while remaining in touch with the audience. My approach to the class involves a dynamic lecture format that incorporates a wide array of multimedia, analogue demonstrations of volcanic processes, and small-group discussions of topics and concepts. In addition to teaching about volcanoes—a fascinating subject in and of itself—I take the opportunity in the first two weeks to introduce students to basic geology, including tectonics, earth materials, surface processes, and geologic time. In fact, this is a vital segment of the class, as the students need this background for the latter portions of the class. A side benefit is that students are provided with a "mini" education in geology whether they know it or not and take this knowledge with them into other classes, and ultimately, their futures. Student satisfaction is uniformly very high with this class. 100% of students agreed that the course material was intellectually stimulating; 95% of students agreed that they learned a great deal from the course; 100% of students stated that they would recommend the class to other students. Overall, the class highlights the role that non-major introductory-level geoscience classes, in particular ones with interesting topics, can serve in educating college-level students about Earth Science. They may also serve as a gateway into the Earth Sciences for students who previously had no such inclination.
