    The Airborne Arctic Stratospheric Expedition had two primary objectives: to study the production and loss mechanisms of ozone in the north polar stratosphere and to study the effect on ozone distribution of the Arctic Polar Vortex and of the cold temperatures associated with the formation of Polar Stratospheric Clouds. Two specially instrumented NASA aircraft were flown over the Arctic region. Each aircraft flew to acquire data on the meteorological, chemical and cloud physical phenomena that occur in the polar stratosphere during winter. The chemical processes which occur in the polar stratosphere during winter were also observed and studied. The data acquired are being analyzed.

    The sudden onset of ozone depletion in the antarctic vortex set a precedent for both the time scale and the severity of global change. The Airborne Antarctic Ozone Experiment (AAOE), staged from Punta Arenas, Chile, in 1987, established that CFCs, halons, and methyl bromide, the dominant sources of chlorine and bromine radicals in the stratosphere, control the rate of ozone destruction over the Antarctic; that the vortex is depleted in reactive nitrogen and water vapor; and that diabatic cooling during the antarctic winter leads to subsidence within the vortex core, importing air from higher altitudes and lower latitudes. This last conclusion is based on observed dramatic distortion in the tracer fields, most notably N2O. In 1989, the first Airborne Arctic Stratospheric Expedition (AASE-I), staged from Stavanger, Norway, and using the same aircraft employed for AAOE (the NASA ER-2 and the NASA DC-8), discovered that while NO(x) and to some degree NO(y) were perturbed within the arctic vortex, there was little evidence for desiccation. Under these (in contrast to the antarctic) marginally perturbed conditions, however, Cl0 was found to be dramatically enhanced such that a large fraction of the available (inorganic) chlorine resided in the form of Cl0 and its dimer ClOOCl. This leaves two abiding issues for the northern hemisphere and the mission of the second Airborne Arctic Stratospheric Expedition (AASE-II): (1) Will significant ozone erosion occur within the arctic vortex in the next ten years as chlorine loading in the stratosphere exceeds four parts per billion by volume? and (2) Which mechanisms are responsible for the observed ozone erosion poleward of 30 deg N in the winter/spring northern hemisphere reported in satellite observations?

    This paper presents an introduction to the initial scientific results of the Airborne Arctic Stratospheric Expedition (AASE), as well as data from other atmospheric experiments and analyses carried out during the Arctic polar winter of 1989. Mission objectives of the AASE were to study the mechanisms of ozone depletion and redistribution in the northern polar stratosphere, including the influences of Arctic meteorology, and polar stratospheric clouds formed at low temperatures. Some major aspects of the AASE are described including: logistics and operations, meteorology, polar stratospheric clouds, trace composition and chemistry, and ozone depletion. It is concluded that the Arctic-89 experiments have provided the scientific community with a wealth of new information that will contribute to a better understanding of the polar winter stratosphere and the critical problem of global ozone depletion.

    Mt. Kilimanjaro, Africa's highest mountain is 5,895 meters above sea level and is located 330 km south of the equator in Tanzania. In 1976 glaciers covered most of Mt. Kilimanjaro's summit; however in 2000, an estimated eighty percent of the ice cap has disappeared since the last thorough survey done in 1912. There is increased scientific interest in Mt. Kilimanjaro with the increase in global and African average temperatures. A team of college and pre-college school students from Tanzania, South Africa and Kenya, teachers from South Africa and the United States, and scientists from the University of Alaska Fairbanks in the United States and Akita University in Japan, climbed to the summit of Mt Kilimanjaro in October 2009. They were accompanied by guides, porters, two expedition guests, and a videographer. This expedition was part of the GLOBE Seasons and Biomes Earth System Science Project and the GLOBE Africa science education initiative, exploring and contributing to climate change studies. Students learned about earth science experientially by observing their physical and biological surroundings, making soil and air temperature measurements, participating in discussions, journaling their experience, and posing research questions. The international trekkers noted the change in the biomes as the altitude, temperature and conditions changed, from cultivated lands, to rain forest, heath zone, moorland, alpine desert, and summit. They also discovered permafrost, but not at the summit as expected. Rather, it was where the mountain was not covered by a glacier and thus more exposed to low extreme temperatures. This was the first report of permafrost on Mt. Kilimanjaro. Classrooms from all over the world participated in the expedition virtually. They followed the trek through the expedition website (http://www.xpeditiononline.com/) where pictures and journals were posted, and posed their own questions which were answered by the expedition and base camp team members

    APECS-France, the French national committee of the Association of Polar Early Career Scientists (APECS), was created in 2013 to improve the dissemination of polar sciences towards the general public and school children in particular, through activities developed in French for French schools. During the autumn of 2014, a young polar oceanographer from the University Pierre and Marie Curie, Zoé Koenig, participated in an expedition on board a sailing vessel in the Southern Ocean. APECS-France set up a new education and outreach project called "Zoé en Expé". Using different media, about 800 children, aged 6 to 12, and from 40 schools, were actively involved in the project. Interactions between Zoé and the students occurred before, during, and after the expedition, through a newsletter, a blog updated in real-time during the expedition, webinars (interactive video-conferences), and visits in classrooms when possible. Teachers were given a list of websites dedicated to polar and oceanographic science outreach and activities adapted to the age and level of the students were offered. Different activities were developed around the expedition, depending on teachers' objectives and children affinities. In particular, students were able to relate to the expedition by imagining a day in the life of Chippy, the mascot of the expedition. They were then asked to draw and/or write Chippy's adventures. APECS-France is now planning to edit a children's book using students' drawings as well as photographs taken during the expedition. Older students were also able to follow in real-time sensors released in the Southern Ocean by Zoé, measuring salinity and temperature. Throughout this 3-month project, children were able to study a wide range of topics (oceanography, biology, history, geography…). The expedition and the educational project allowed raising the awareness of children about the fragile and badly known Antarctic environment.

    Stratospheric ozone and aerosol distributions were measured across the wintertime Arctic vortex from January to March 1992 with an airborne lidar system as part of the 1992 Airborne Arctic Stratospheric Expedition (AASE II). Aerosols from the Mount Pinatubo eruption were found outside and inside the vortex with distinctly different distributions that clearly identified the dynamics of the vortex. Changes in aerosols inside the vortex indicated advection of air from outside to inside the vortex below 16 kilometers. No polar stratospheric clouds were observed and no evidence was found for frozen volcanic aerosols inside the vortex. Between January and March, ozone depletion was observed inside the vortex from 14 to 20 kilometers with a maximum average loss of about 23 percent near 18 kilometers.

    1992-01-01

    Results are presented of a study of the radiative effects of polar stratospheric clouds during the Airborne Antarctic Ozone Experiment (AAOE) and the Airborne Arctic Stratospheric Expedition (AASE) in which daily 3D Type I nitric acid trihydrate (NAT) and Type II water ice polar stratospheric clouds (PSCs) were generated in the polar regions during AAOE and the AASE aircraft missions. Mission data on particular composition and size, together with NMC-analyzed temperatures, are used. For AAOE, both Type I and Type II clouds were formed for the time period August 23 to September 17, after which only Type I clouds formed. During AASE, while Type I clouds were formed for each day between January 3 and February 10, Type II clouds formed on only two days, January 24 and 31. Mie theory and a radiative transfer model are used to compute the radiative heating rates during the mission periods, for clear and cloudy lower sky cases. Only the Type II water ice clouds have a significant radiative effect, with the Type I NATO PSCs generating a net heating or cooling of 0.1 K/d or less.

    Simulations of the evolution of stratospheric distributions of hydrogen chloride (HCl) and hydrogen fluoride (HF) have been carried out for the period of the Airborne Arctic Stratospheric Expedition (AASE) with a three-dimensional chemistry-transport model. Simulations were performed assuming only homogeneous gas phase chemistry for HF and both homogeneous gas phase and heterogeneous chemistry for HCl. Results show heterogeneous loss of HCl is needed to provide agreement with infrared column measurements. Estimates of the impact of heterogeneous loss on the global HCl distribution are obtained from the model. Reductions of HCl due to heterogeneous loss are calculated to be localized to regions of high vorticity, even after more than a month of integration.

    Composite distributions of measured total reactive nitrogen NO(y), from the NASA ER-2 during the Airborne Arctic Stratospheric Expedition are presented. The observed features of these distributions are discussed in terms of the controlling dynamical, chemical and microphysical processes. In the latitudinal profile from 58 deg N to within about 4 deg poleward of the polar vortex boundary, NO(y) conforms closely to predictions of NO(y) based on N2O measurements. Poleward of 5 deg of latitude within the boundary, the average NO(y) decreases sharply and is significantly lower than that predicted from N2O. This feature is consistent with loss of NO(y) through sedimentation of particles containing NO(y) in polar stratospheric clouds.

    The Coastal and Ocean Airborne Science Testbed (COAST) Project is a NASA Earth-science flight mission that will advance coastal ecosystems research by providing a unique airborne payload optimized for remote sensing in the optically complex coastal zone. Teaming NASA Ames scientists and engineers with Biospherical Instruments, Inc. (San Diego) and UC Santa Cruz, the airborne COAST instrument suite combines a customized imaging spectrometer, sunphotometer system, and a new bio-optical radiometer package to obtain ocean/coastal/atmosphere data simultaneously in flight for the first time. The imaging spectrometer (Headwall) is optimized in the blue region of the spectrum to emphasize remote sensing of marine and freshwater ecosystems. Simultaneous measurements supporting empirical atmospheric correction of image data will be accomplished using the Ames Airborne Tracking Sunphotometer (AATS-14). Based on optical detectors called microradiometers, the NASA Ocean Biology and Biogeochemistry Calibration and Validation (cal/val) Office team has deployed advanced commercial off-the-shelf instrumentation that provides in situ measurements of the apparent optical properties at the land/ocean boundary including optically shallow aquatic ecosystems (e.g., lakes, estuaries, coral reefs). A complimentary microradiometer instrument package (Biospherical Instruments, Inc.), optimized for use above water, will be flown for the first time with the airborne instrument suite. Details of the October 2011 COAST airborne mission over Monterey Bay demonstrating this new airborne instrument suite capability will be presented, with associated preliminary data on coastal ocean color products, coincident spatial and temporal data on aerosol optical depth and water vapor column content, as well as derived exact water-leaving radiances.

    In situ measurements of NO and NO2 were made simultaneously from the NASA DC-8 aircraft as part of the Airborne Arctic Stratospheric Expedition. Mixing ratios of NO(x) (NO + NO2) were typically higher in the arctic troposphere than in the stratosphere, with median values of 59 and 40 pptv, respectively. In the stratosphere, there tended to be a positive correlation between NO(x) and water vapor and negative correlations between NO(x) and ozone and between NO(x) and total reactive odd-nitrogen, NO(y). The ratio of NO(x) to NO(y), in conjunction with NO(y), appears to be an excellent tracer of tropospheric or stratospheric air at northern latitudes during winter. Tropospheric NO(x) was typically 10 to 50 percent of gas-phase NO(y), while in the stratosphere, NO(x) was typically less than 10 percent, and frequently less than 5 percent of gas-phase NO(y).

    The Haughton-Mars expedition is a multidisciplinary project, exploring an impact crater in an extreme environment to determine how people might live and work on Mars. The expedition seeks to understand and field test Mars facilities, crew roles, operations, and computer tools. I combine an ethnographic approach to establish a baseline understanding of how scientists prefer to live and work when relatively unemcumbered, with a participatory design approach of experimenting with procedures and tools in the context of use. This paper focuses on field methods for systematically recording and analyzing the expedition's activities. Systematic photography and time-lapse video are combined with concept mapping to organize and present information. This hybrid approach is generally applicable to the study of modern field expeditions having a dozen or more multidisciplinary participants, spread over a large terrain during multiple field seasons.

    The National Aeronautics and Space Administration conducts a wide variety of remote sensing projects using several unique aircraft platforms. These vehicles have been selected and modified to provide capabilities that are particularly important for geophysical research, in particular, routine access to very high altitudes, long range, long endurance, precise trajectory control, and the payload capacity to operate multiple, diverse instruments concurrently. While the NASA program has been in operation for over 30 years, new aircraft and technological advances that will expand the capabilities for airborne observation are continually being assessed and implemented. This presentation will review the current state of NASA's science platforms, recent improvements and new missions concepts as well as provide a survey of emerging technologies unmanned aerial vehicles for long duration observations (Global Hawk and Predator). Applications of information technology that allow more efficient use of flight time and the ability to rapidly reconfigure systems for different mission objectives are addressed.

    Three high school seniors from High Tech High (HTH) participated in the ALIA expedition that explored the Samoan hot spot track through seafloor mapping, rock sampling and the study of the water column above an active submarine volcano. The primary responsibility of the HTH participants focused on outreach and education, but they also were substantively involved in all scientific aspects of the cruise. Education and outreach activities included: maintaining the cruise website,the creation of ERESE digital library resources for earth science education, live video-conferences with students half a world away in San Diego, and offering tours of the Research Vessel Kilo Moana during an open house event organized with the Samoa Department of Eduation. At this occasion, the HTH seniors shared experiences and knowledge with the visiting Samoan elementary and high school students. Science involvement of the high school seniors included deck and laboratory work, by assisting with dredging, piston coring, rock cataloguing, casting CTDs, and computer programming. Three major computer programming efforts by the HTH seniors substantively supported the outreach activities and the science operations during ALIA. (1) The development of "CustomHTMLExport", a utility that allows for the export of photographs and their metadata into web pages and digital library collection. (2) The "CruiseWatch" featureson the ALIA website (http://earthref.org/ERESE/projects/ALIA/) that displays in near - real time key shipboard data such as the location on a map, geographic coordinates, ship speed, direction and wind speed and dredging data. (3) A dredge location simulator to predict the location of the dredge with respect to the ship and the seafloor which was made necessary for the safety of dredging due to the failure of pingers that normally are used to provide critical data for the location of the dredge with respect to the seafloor. The dredge location model is based a fluid dynamics approach

Simultaneous measurements supporting empirical atmospheric correction of image data is accomplished using the Ames Airborne Tracking Sunphotometer (AATS-14). Coastal Airborne In situ Radiometers (C-AIR, Biospherical Instruments, Inc.), developed for COAST for airborne campaigns from field-deployed microradiometer instrumentation, will provide measurements of apparent optical properties at the land/ocean boundary including optically shallow aquatic ecosystems. Ship-based measurements allowed validation of airborne measurements. Radiative transfer modeling on in-water measurements from the HyperPro and Compact-Optical Profiling System (C-OPS, the in-water companion to C-AIR) profiling systems allows for comparison of airborne and in-situ water leaving radiance measurements. Results of the October 2011 Monterey Bay COAST mission include preliminary data on coastal ocean color products, coincident spatial and temporal data on aerosol optical depth and water vapor column content, as well as derived exact water-leaving radiances.

    Government funding is the cornerstone of modern science. But with declining investment in science across most of the Western World, a major challenge for society is where best to place what little resource we have. Which research questions should have the greatest priority? Nowhere are these issues more pressing than in the Antarctic, where bases have and continue to play host to 'big-science', multi-year programmes of research, locking up logistical support and costs. But in a warming world, the areas with the greatest effects of climate change aren't always near government research stations. With this in mind, in 2012 a plan was formed to visit Commonwealth Bay, a remote area off the East Antarctic Ice Sheet, where in 2010, an iceberg the size of Rhode Island, known as B09B, dramatically knocked a 60-mile long tongue of ice off the Mertz Glacier into the Southern Ocean, setting off a cascade of change. Inspired by the expeditions of the past, we advertised berths for sale to take citizen scientists south with us, harnessing their interest, experience and investment. People responded far and wide. We were oversubscribed, and the Australasian Antarctic Expedition 2013-2014 was born. With the Russian-owned MV Akademik Shokalskiy as the expedition vessel, we set out south from the New Zealand port of Bluff in late November 2013. During our journey south and on the ice we undertook a number of scientific firsts for the region actively engaging the volunteer scientists on board in projects ranging from oceanography, biology, ecology, geology and glaciaology. The expedition demostrated how private funding could support targeted programmes of research and communicate it to the wider world. Small-science research can capture the public's imagination and also reap real scientific outputs. Although it is a funding model developed in the Antarctic a hundred years ago, the beauty is it can applied anywhere in the world.

    The Joint Antarctic School Expedition (JASE) is an international collaboration program between high school students and teachers from the United States and Chile aimed at providing the skills required for establishing the scientific international collaborations that our globalized world demands, and to develop a new approach for science education. The National Antarctic Programs of Chile and the United States worked together on a pilot program that brought high school students and teachers from both countries to Punta Arenas, Chile, in February 2014. The goals of this project included strengthening the partnership between the two countries, and building relationships between future generations of scientists, while developing the students' awareness of global scientific issues and expanding their knowledge and interest in Antarctica and polar science. A big component of the project involved the sharing by students of the acquired knowledge and experiences with the general public. JASE is based on the successful Chilean Antarctic Science Fair developed by Chile´s Antarctic Research Institute. For 10 years, small groups of Chilean students, each mentored by a teacher, perform experimental or bibliographical Antarctic research. Winning teams are awarded an expedition to the Chilean research station on King George Island. In 2014, the Chileans invited US participation in this program in order to strengthen science ties for upcoming generations. On King George Island, students have hands-on experiences conducting experiments and learning about field research. While the total number of students directly involved in the program is relatively small, the sharing of the experience by students with the general public is a novel approach to science education. Research experiences for students, like JASE, are important as they influence new direction for students in science learning, science interest, and help increase science knowledge. We will share experiences with the

    A system providing a common core set of facility data services across the NASA Airborne Science Program research aircraft fleet is described. The NASA Airborne Science Data And Telemetry System (NASDAT) is a rugged avionics box that fits in a standard aeronautical radio rack mounting tray, and provides both aircraft and experimenter data interfaces. Ethernet, satcom, and legacy connections are supported. Standardized protocols allow this system to serve as an abstraction layer for interfacing any instrument to any aircraft. Built-in Iridium modems allow low rate baseline global data communications. Built on open standards and dynamically reconfigurable, the NASDAT enables any research platform to participate in the wider sensor web, such that remote experimenters can control their instruments, and display applications can receive near real time data. The production NASDAT was built this year, based in part on prototypes which have been flying on several research aircraft such as the NASA DC-8 and Global Hawk.

    Classroom teachers are challenged with engaging and preparing today’s students for the future. Activities are driven by state required skills, education standards, and high stakes testing. How can educators teach required standards and motivate students to not only learn essential skills, but also acquire a sense of intrigue to want to learn more? One way is to allow students to take charge of their learning and conduct student-driven research. NASA’s Expedition Earth and Beyond program, based at the NASA Johnson Space Center, is designed to do just that. The program, developed by both educators and scientists, promotes inquiry-based investigations in classrooms (grades 5-14) by using current NASA data. By combining the expertise of teachers, who understand the everyday challenges of working with students, and scientists, who work with the process of science as they conduct their own research, the result is a realistic and useable means in which to promote authentic research in classrooms. NASA’s Expedition Earth and Beyond Program was created with the understanding that there are three important aspects that enable teachers to implement authentic research experiences in the classroom. These aspects are: 1) Standards-aligned, inquiry based curricular resources and an implementation structure to support student-driven research; 2) Professional development opportunities to learn techniques and strategies to ensure seamless implementation of resources; and 3) Ongoing support. Expedition Earth and Beyond provides all three of these aspects and adds two additional and inspiring motivators. One is the opportunity for student research teams to request new data. Data requested and approved would be acquired by astronauts orbiting Earth on the International Space Station. This aspect is part of the process of science structure and provides a powerful way to excite students. The second, and perhaps more significant motivator, is the creation of connections between

    NASA earth science instruments are increasingly relying on airborne missions. However, traditionally, there has been limited common infrastructure support available to principal investigators in the area of science data systems. As a result, each investigator has been required to develop their own computing infrastructures for the science data system. Typically there is little software reuse and many projects lack sufficient resources to provide a robust infrastructure to capture, process, distribute and archive the observations acquired from airborne flights. At NASA's Jet Propulsion Laboratory (JPL), we have been developing a multi-mission data system infrastructure for airborne instruments called the Airborne Cloud Computing Environment (ACCE). ACCE encompasses the end-to-end lifecycle covering planning, provisioning of data system capabilities, and support for scientific analysis in order to improve the quality, cost effectiveness, and capabilities to enable new scientific discovery and research in earth observation. This includes improving data system interoperability across each instrument. A principal characteristic is being able to provide an agile infrastructure that is architected to allow for a variety of configurations of the infrastructure from locally installed compute and storage services to provisioning those services via the "cloud" from cloud computer vendors such as Amazon.com. Investigators often have different needs that require a flexible configuration. The data system infrastructure is built on the Apache's Object Oriented Data Technology (OODT) suite of components which has been used for a number of spaceborne missions and provides a rich set of open source software components and services for constructing science processing and data management systems. In 2010, a partnership was formed between the ACCE team and the Carbon in Arctic Reservoirs Vulnerability Experiment (CARVE) mission to support the data processing and data management needs

    The Carbon in Arctic Reservoirs Vulnerability Experiment (CARVE) mission collects detailed measurements of important greenhouse gases on local to regional scales in the Alaskan Arctic and demonstrates new remote sensing and improved modeling capabilities to quantify Arctic carbon fluxes and carbon cycle-climate processes. Airborne missions offer a number of challenges when it comes to collecting and processing the science data and CARVE is no different. The biggest challenge relates to the flexibility of the instrument payload. Within the life of the mission, instruments may be removed from or added to the payload, or even reconfigured on a yearly, monthly or daily basis. Although modification of the instrument payload provides a distinct advantage for airborne missions compared to spaceborne missions, it does tend to wreak havoc on the underlying data system when introducing changes to existing data inputs or new data inputs that require modifications to the pipeline for processing the data. In addition to payload flexibility, it is not uncommon to find unsupported files in the field data submission. In the case of CARVE, these include video files, photographs taken during the flight and screen shots from terminal displays. These need to captured, saved and somehow integrated into the data system. The CARVE data system was built on a multi-mission data system infrastructure for airborne instruments called the Airborne Cloud Computing Environment (ACCE). ACCE encompasses the end-to-end lifecycle covering planning, provisioning of data system capabilities, and support for scientific analysis in order to improve the quality, cost effectiveness, and capabilities to enable new scientific discovery and research in earth observation. This well-tested and proven infrastructure allows the CARVE data system to be easily adapted in order to handle the challenges posed by the CARVE mission and to successfully process, manage and distribute the mission's science data.

    On 23 October a partial solar eclipse occurred across parts of the southwest United States between approximately 21:09 and 23:40 (UT), with maximum obscuration, 36%, occurring at 22:29 (UT). During 21-26 October 2014 the Mojave Volatile Prospector (MVP) field expedition deployed and operated the NASA Ames Krex2 rover in the Mojave desert west of Baker, California (Fig. 1, bottom). The MVP field expedition primary goal was to characterize the surface and sub-surface soil moisture properties within desert alluvial fans, and as a secondary goal to provide mission operations simulations of the Resource Prospector (RP) mission to a Lunar pole. The partial solar eclipse provided an opportunity during MVP operations to address serendipitous science. Science instruments on Krex2 included a neutron spectrometer, a near-infrared spectrometer with associated imaging camera, and an independent camera coupled with software to characterize the surface textures of the areas encountered. All of these devices are focused upon the surface and as a result are downward looking. In addition to these science instruments, two hazard cameras are mounted on Krex2. The chief device used to monitor the partial solar eclipse was the engineering development unit of the Near-Infrared Volatile Spectrometer System (NIRVSS) near-infrared spectrometer. This device uses two separate fiber optic fed Hadamard transform spectrometers. The short-wave and long-wave spectrometers measure the 1600-2400 and 2300-3400 nm wavelength regions with resolutions of 10 and 13 nm, respectively. Data are obtained approximately every 8 seconds. The NIRVSS stares in the opposite direction as the front Krex2.

    martian meteorite, evidence of past and perhaps even present liquid water on Mars, the likelihood of a liquid water ocean on Europa, the possibility of liquid water beneath the surface of Titan, observations of a growing number of extrasolar planets, and identification of new forms of microbial life in an ever-widening range of extreme Earth environments. Consequently, in the 21st century the pace of robotic planetary exploration is speeding up and scientific and public attention is increasingly focusing on astrobiology research, especially the search for signs of life on Mars and in other environments in our solar system. NASA's ASTEP program is sponsoring field campaigns to test science strategies and robotic technologies that could be useful in conducting astrobiological investigations in planetary environments, focusing on Mars and Europa. Public interest in astrobiology research is substantial, and advances in the field are rapid. Thus the NASA Astrobiology Program encourages Principal Investigators to incorporate communication, education, and public outreach initiatives in their research plans. NASA ASTEP projects provide especially good opportunities for communication, education, and outreach. The work of ASTEP projects takes place in remote terrestrial environments, places typically inaccessible to "civilians": the Norwegian protectorate of Svalbard, above the Arctic Circle; the far-northern reaches of the Arctic Ocean; the dry valleys of Antarctica; deep-sea hydrothermal vent systems and other unmapped underwater environments. ASTEP projects involve human researchers working with robotic adjuncts. ASTEP teams often combine include senior and student researchers. Some have even included "embedded" journalists and public affairs officers. ASTEP expeditions typically unfold in visually interesting, sometimes stunning, physical environments. ASTEP expeditions are virtually always intensive learning experiences for their researchers, and thus they provide good

    Cattadori, Matteo

    2016-04-01

    RESEt (Research and Education Svalbard Experience www.resetsvalbard.it) is an ongoing educational project focusing mainly on polar and climate system topics. It started in 2014 and will end in 2017 with the high school diploma of the 22 students (16 y. o.) making the participant class. This class attend a school (Liceo Filzi, Rovereto, Trento. Italy) with a primary focus on disciplines like philosophy and education, rather then STEM (Science, Technology, Engineering, and Mathematics). Nevertheless their science curricula include climate topics that are rather challenging to grasp and, at the same time, crucial for their scientific citizenship. Some questions arise: How to foster their interest in geosciences topics? How to engage them in authentic scientific knowledge? How to increase their interest in scientific university courses during their post-secondary career? RESEt project will attempt to answer these questions through the development of integrated activities distributed over the last three years of their high school cycle. The most important moment will be an educational scientific expedition at the Svalbard, an archipelago located in the Arctic. The expedition be entirely organized, planned, and directed by students. In Svalbard, students will visit the main scientific facilities devoted to climate studies including those of Italian CNR (National Research Council) and they will perform some environmental measurement using data-loggers. Students are even involved in the fundraising process to raise more than ten thousand Euros needed to for travel expenses. This work is aimed mainly at presenting some of the preliminary data collected during the RESEt project, including the fundraising aspects. The management of the RESEt project strongly relies on the experience and network gained by the abstract author during the participation to the Education and Public Outreach (EPO) program of International Polar Year (IPY) 2007-2009 as well as the support of Polar

    Collection of data during airborne field campaigns is a critically important endeavor. It is imperative to observe the correct phenomena at the right time - at the right place to maximize the instrument observations. Researchers at NASA Marshall Space Flight Center have developed an application suite known as the Real Time Mission Monitor (RTMM). This suite is comprised of tools for mission design, flight planning, aircraft visualization and tracking. The mission design tool allows scientists to set mission parameters such as geographic boundaries and dates of the campaign. Based on these criteria, the tool intelligently selects potential data sets from a data resources catalog from which the scientist is able to choose the aircraft, instruments, and ancillary Earth science data sets to be provided for use in the remaining tool suite. The scientists can easily reconfigure and add data sets of their choosing for use during the campaign. The flight planning tool permits the scientist to assemble aircraft flight plans and to plan coincident observations with other aircraft, spacecraft or in situ observations. Satellite and ground-based remote sensing data and modeling data are used as background layers to aid the scientist in the flight planning process. Planning is crucial to successful collection of data and the ability to modify the plan and upload to aircraft navigators and pilots is essential for the agile collection of data. Most critical to successful and cost effective collection of data is the capability to visualize the Earth science data (airborne instruments, radiosondes, radar, dropsondes, etc.) and track the aircraft in real time. In some instances, aircraft instrument data is provided to ground support personnel in near-real time to visualize with the flight track. This visualization and tracking aspect of RTMM provides a decision support capability in conjunction with scientific collaboration portals to allow for scientists on the ground to communicate

  1. Guiding science expeditions: The design of a learning environment for project-based science

    NASA Astrophysics Data System (ADS)

    Polman, Joseph Louis

    Project-based pedagogy has been revived recently as a teaching strategy for promoting students' active engagement in learning science by doing science. Numerous reform efforts have encouraged project-based teaching in high schools, along with a range of supports for its implementation, often including computers and the Internet. History has shown, however, that academic research and new technologies are not enough to effect real change in classrooms. Ultimately, teachers accomplish activity with their students daily in classrooms. Putting the idea of project-based teaching into practice depends on many particulars of teachers' situated work with students. To better understand the complexity of project-based science teaching in schools, I conducted an interpretive case study of one exceptional teacher's work. The teacher devotes all class time after the beginning of the year to open-ended, student-designed Earth Science research projects. Over four years of involvement with the Learning through Collaborative Visualization (CoVis) reform effort, this teacher has developed, implemented, and refined strategies for supporting and guiding students in conducting open-ended inquiry. Through a close examination of the teacher's work supporting student projects, I explore the design issues involved in such an endeavor, including affordances, constraints, and tradeoffs. In particular, I show how time constrains both student and teacher action, how the traditional school culture and grading create stumbling blocks for change, and how conflicting beliefs about teaching and learning undermine the accomplishment of guided inquiry. I also show how Internet tools including Usenet news, email, and the World Wide Web afford students an opportunity to gather and make use of distributed expertise and scientific data resources; how an activity structure, combined with a corresponding structure to the artifact of the final written product, supports student accomplishment of unfamiliar

    This paper describes a unique validation data set acquired from a marine intensive observing period (IOP) conducted on board the NOAA Ship Ronald H. Brown (RHB) during the 2004 Aerosol and Ocean Science Expedition (AEROSE) in the tropical North Atlantic Ocean from 29 February to 26 March 2004. The radiometric and in situ data complement includes marine observations of the Saharan air layer (SAL), including two significant Saharan dust outbreaks over the Atlantic Ocean. Because the impact of tropospheric dust aerosols on satellite infrared (IR) radiometric observations has not yet been fully characterized, the AEROSE data are particularly valuable for IR sensor validation. Shipboard radiometric data germane to satellite validation include observations from a Marine Atmospheric Emitted Radiance Interferometer (M-AERI), a Calibrated Infrared In situ Measurement System (CIRIMS), and Microtops handheld sunphotometers. Among other things, these data provide, for the first time, coincident IR spectra of the dry, dusty SAL from both the uplooking M-AERI and the downlooking Atmospheric Infrared Sounder (AIRS) on board the Aqua satellite. In situ data collected throughout the cruise include Vaisala RS80/90 radiosondes, launched ≃3-hourly to include Aqua overpass times. The Aqua matchup profiles provide data for validation of AIRS in the presence of high dust loading, along with temperature and water vapor profile retrievals of the SAL. The frequency of sonde launches also enables validation of coincident uplooking M-AERI boundary layer profile retrievals. Preliminary analyses of the AEROSE data are presented here. Focused AEROSE validation studies are the subjects of separate papers.

    From October 1 through September 30, 2016, the Atmospheric Radiation Measurement (ARM) Aerial Facility will deploy the Cessna 206 aircraft over the Southern Great Plains (SGP) site, collecting observations of trace-gas mixing ratios over the ARM’s SGP facility. The aircraft payload includes two Atmospheric Observing Systems, Inc., analyzers for continuous measurements of CO2 and a 12-flask sampler for analysis of carbon cycle gases (CO2, CO, CH4, N2O, 13CO2, 14CO2, carbonyl sulfide, and trace hydrocarbon species, including ethane). The aircraft payload also includes instrumentation for solar/infrared radiation measurements. This research is supported by the U.S. Department of Energy’s ARM Climate Research Facility and Terrestrial Ecosystem Science Program and builds upon previous ARM Airborne Carbon Measurements (ARM-ACME) missions. The goal of these measurements is to improve understanding of 1) the carbon exchange at the SGP site, 2) how CO2 and associated water and energy fluxes influence radiative forcing, convective processes and CO2 concentrations over the SGP site, and 3) how greenhouse gases are transported on continental scales.

    The WWW provides for new collaborations in distributed learning in higher education. The lead author has developed a highly successful online course at the undergraduate level with an enrollment of more than 300 non-science majors each year, We are currently initiating a new focus for the course by emphasizing sea-going research, primarily in the northeastern Pacific Ocean, through the development of a virtual oceanographic voyage over the WWW. The "virtual voyage" courseware combines elements of experiential learning with anytime, anywhere access of the WWW to stimulate inquiry-based learning in the ocean sciences. The first leg of the voyage is currently being synthesized from contemporary ocean research sponsored by a collaboration of U.S. government agencies, including NSF, NOAA, and the USGS. The initial portion of this effort involves transforming portions of USGS Circular 1198, Beyond the Golden Gate -- Oceanography, Geology, Biology, and Environmental Issues in the Gulf of the Farallones, into an interactive expedition by which students participate as scientists aboard a research vessel departing from San Francisco. Virtual experiments on the voyage are patterned after research cruises over the past decade in two national marine sanctuaries and include the technologies of data acquisition and data analysis, as well as providing insight into the methodologies of working marine scientists. Real-time data for monitoring the marine environment are embedded into several modules; for example, students will analyze data from offshore buoys and satellite imagery to assess ocean conditions prior to departing from port. Multibeam sonar is used to create seafloor maps near the Golden Gate Bridge and sediment cores provide evidence of sea-level change in the region. Environmental studies in the region include locating canisters of low-level radioactive waste and assessing potential sites for the disposal for dredged materials from the San Francisco Bay.

    2006-12-01

    The ARMADA Project, funded by NSF and administered through the University of Rhode Island Office of Marine Programs, pairs 12-14 teachers with ocean, polar, and environmental scientists each year, affording these teachers an authentic research experience. One middle-school science teacher, Kathleen Couchon of Narragansett, Rhode Island, participated in the IODP Arctic Coring Expedition (ACEX) in the summer of 2004. Sailing for 6 weeks aboard the Swedish Icebreaker Oden, Kathleen participated in many aspects of the polar ocean-drilling expedition and was accepted by scientists and crew alike as part of the international science party. Upon return to the classroom, Kathleen found multiple opportunities to share her Arctic research experiences through effective public outreach both within and outside of the educational community. In the classroom, she has developed and implemented inquiry-based activities, allowing her students the opportunity to function as scientists themselves. Mentoring new science teachers within the district and presenting multi- media presentations to other teachers and students at the Narragansett Pier Middle School and Narragansett High School in Rhode Island, provided a wider audience for this important polar geoscience enterprise. An expanded circle of impact was gained through presentations at local district, state, and national teacher gatherings, including two National Science Teacher Association annual conventions and a high school audience at Arcadia High School in Phoenix, Arizona. Within the community-at-large, Kathleen has impacted diverse audiences including the Girl Scouts, the Rotary Club, and senior citizen groups - all enthusiastically receptive and appreciative of hearing the scientific news of research from the North Pole. These experiences have served to establish a linkage between the scientific community and the public, with a teacher-researcher sharing and interpreting the scientific research goals and methodologies, as

    For many years NASA has supported the collection of in-situ and remotely sensed science data through the use of airborne platforms. The Airborne Science Program, as part of NASA's Earth Science Division (ESD), currently supports and manages these investigations. The data collected under this program have many uses including, but certainly not limited to, calibration and validation of satellite based measurements and retrieval algorithms, testing new sensor technologies, and measuring the vertical and horizontal distribution of atmospheric constituents. In the past, management of the data was typically the responsibility of the individual principal investigators. Along the way many highly customized strategies for dealing with data discovery, access, distribution, formatting, and preservation issues were developed. In an effort to assure that airborne science data are managed in a more coherent and uniform manner across the program, airborne missions are now being required to adhere to the NASA Earth science data policy and a specific set of Level 1 data management requirements derived from that policy. These requirements include use of NASA ESD-approved data formats and metadata specifications, elimination of periods of exclusive access, and the transfer of data products to a NASA ESD-assigned Data Center. In addition, the manner in which each mission plans to meet these requirements must be documented in a data management plan. The good news is that there is a significant Earth science data management infrastructure in place that can be leveraged to help meet these requirements. However, much of this infrastructure was developed to support satellite missions. Since airborne data are different than satellite data in many ways, this presents some challenges. This presentation will describe the challenges as well as the benefits of this new data management policy.

    An airborne thermal hyperspectral imager is under development which utilizes the compact Dyson optical configuration and quantum well infrared photo detector (QWIP) focal plane array. The Dyson configuration uses a single monolithic prism-like grating design which allows for a high throughput instrument (F/1.6) with minimal ghosting, stray-light and large swath width. The configuration has the potential to be the optimal imaging spectroscopy solution for lighter-than-air (LTA) vehicles and unmanned aerial vehicles (UAV) due to its small form factor and relatively low power requirements. The planned instrument specifications are discussed as well as design trade-offs. Calibration testing results (noise equivalent temperature difference, spectral linearity and spectral bandwidth) and laboratory emissivity plots from samples are shown using an operational testbed unit which has similar specifications as the final airborne system. Field testing of the testbed unit was performed to acquire plots of apparent emissivity for various known standard minerals (such as quartz). A comparison is made using data from the ASTER spectral library.

    The Integrated Ocean Drilling Program (IODP) - United States Implementing Organization (USIO) took advantage of a 16-day break between scientific operations to carry out a seagoing pilot educator workshop on board the JOIDES Resolution during a transit from Victoria, B.C., Canada, to Acapulco, Mexico. During this workshop, 10 educators from all across the United States were mentored and taught by scientists who are actively engaged in IODP research, the USIO Education Director, and staff. In addition, shipboard technical staff provided guidance and content related to hands-on laboratory activities. The pilot program provided the educators with an opportunity to participate in a seagoing experience on a scientific drilling research vessel and conduct a series of research activities similar to those that take place during regular scientific drilling expeditions. The workshop allowed educators to increase their knowledge of IODP and scientific methods as borne out through ocean drilling (proposals, drilling, lab analysis, data acquisition, postcruise activities) as well as knowledge of mid-ocean ridges, composition and structure of the oceanic crust, seafloor spreading, paleoceanography, paleomagnetism, and sedimentology. The workshop participants translated the scientific results into useful teaching resources by developing a suite of new discovery-based activities related to ocean drilling research that will undergo classroom testing by workshop participants. Over the school year the educators will help disseminate IODP science education by conducting at least two teacher workshops based on this seagoing experience, enhanced scientific knowledge gained from participating in the workshop, and the new activities developed en route.

  2. Science at the ends of the Earth: astrobiology field expeditions as outreach tools

    NASA Astrophysics Data System (ADS)

    Billings, Linda

    INTRODUCTION This paper will report on and evaluate communication, education, and outreach initiatives conducted in conjunction with NASA Astrobiology Science and Technology for Exploring Planets (ASTEP) field campaigns, addressing the costs and benefits of linking students, teachers, and other interested citizens with researchers in the field. This paper will highlight success stories, lessons learned, and promising practices regarding educational programs in scientific research environments. The Astrobiology Program in the U.S. National Aeronautics and Space Administration's (NASA's) Science Mission Directorate studies the origin, evolution, distribution, and future of life in the universe. Public interest in astrobiology is great, and advances in the field are rapid. Hence, the Astrobiology Program supports the widest possible dissemination of timely and useful information about scientific discoveries, technology development, new knowledge, and greater understanding produced by its investigators, employing an approach described as strategic communication planning. That is, the Astrobiology Program aims to integrate communication, education, and outreach into all aspects of program planning and execution. The Program encourages all of its investigators to contribute to the ongoing endeavor of informing public audiences about Astrobiology. The ASTEP element of the Astrobiology Program sponsors terrestrial field campaigns to further scientific research and technology development relevant to future solar system exploration missions. ASTEP science investigations are designed to further biological research in terrestrial environments analogous to those found on other planets, past or present. ASTEP sponsors the development of technologies to enable remote searches for, and identification of, life in extreme environments. ASTEP supports systems-level field campaigns designed to demonstrate and validate the science and technology in extreme environments on Earth. This

    The Hawaii Undersea Research Laboratory (HURL) recently completed an internationally partnered 5-month, 14,500 nautical mile multiple leg expedition to the South Pacific that included 21 study sites in the waters of American Samoa, New Zealand, Tonga, and the U.S. Line Islands to commemorate its 25th anniversary of supporting deep submergence science in the Pacific Ocean. During this voyage, HURL successfully operated its two human occupied vehicles ( Pisces IV and Pisces V) each capable of diving to 2000 m from their support ship, the R/V Ka'imikai-o-Kanaloa ( KoK). In addition, a remotely operated vehicle ( RCV-150) with a nearly 1000-m depth limit was utilized alternately with the Pisces HOV's. The size and organized placement of these vehicles on the compact but efficiently run KoK (70-m length, 2000-tons displacement, 14 crew) allowed for deployment of a CTD rosette system and recovery of instrument package moorings during the same cruise leg. The Pisces submersibles are 20-ft long, 13-ton, 3-person vehicles with 7-10 hours duration, up to 350-lb payload capacities, and three forward looking viewports. The small size of the Pisces' relative to much larger deeper diving HOV's increases their agility, thus allowing maneuvering into more difficult sampling site terrain. The smaller package also facilitates rapid launch (8 min avg, stdev=1) and recovery (12 min avg, stdev=2) in heavier seas (up to sea state 5), as routinely experienced in the South Pacific during the austral winter. In addition to the enhanced safety aspect of having two compatible submersibles aboard, scientific efficiency has benefited by allowing the rotation of vehicles on extended deployments prior to battery servicing, thus maintaining an overall dive time average of 7.1 hr (stdev=1.52) for an average dive depth of 891 m (stdev=431) in 2005. Having the two fully operational submersibles also provides a contingency for equipment malfunction while on site that saved 7 dive days in 2005 alone

    This qualitative study describes the experiences of a group of sixteen, eighth grade girls participating in a single-sex, math/science program based on gender equity research and constructivist theory. This phenomenological case study highlights the individual changes each girl perceives in herself as a result of her involvement in this program which was based at a suburban middle school just north of New York City. Described in narrative form is what took place during this single-sex program. At the start of the program the girls worked cooperatively in groups to build canoes. The canoes were then used to study a wetland during the final days of the program. To further immerse the participants into nature, the girls also camped during these final days. Data were collected from a number of sources to uncover, as fully as possible, the true essence of the program and the girls' experiences in it. The data collection methods included direct observation; in-depth, open-ended interviews; and written documentation. As a result of data collection, the girls' perceived outcomes and assessment of the program, as well as their recommendations for future math/science programs are revealed. The researcher in this study also acted as teacher, directing the program, and as participant to better understand the experiences of the girls involved in the program. Thus, unique insights could be made. The findings in this study provide insight into the learning of the participants, as well as into the relationships they formed both inside and outside of the program. Their perceived experiences and assessment of the program were then used to develop a greater understanding as to the effectiveness of this non-traditional program. Although this study echoed much of what research says about the needs of girls in learning situations, and therefore, reinforces previously accepted beliefs, it also reveals significant findings in areas previously unaddressed by gender studies.

    The Earth System Science Pathfinder (ESSP) Program Office (PO) is responsible for programmatic management of National Aeronautics and Space Administration's (NASA) Science Mission Directorate's (SMD) Earth Venture (EV) missions. EV is composed of both orbital and suborbital Earth science missions. The first of the Earth Venture missions is EV-1, which are Principal Investigator-led, temporally-sustained, suborbital (airborne) science investigations costcapped at $30M each over five years. Traditional orbital procedures, processes and standards used to manage previous ESSP missions, while effective, are disproportionally comprehensive for suborbital missions. Conversely, existing airborne practices are primarily intended for smaller, temporally shorter investigations, and traditionally managed directly by a program scientist as opposed to a program office such as ESSP. In 2010, ESSP crafted a management approach for the successful implementation of the EV-1 missions within the constructs of current governance models. NASA Research and Technology Program and Project Management Requirements form the foundation of the approach for EV-1. Additionally, requirements from other existing NASA Procedural Requirements (NPRs), systems engineering guidance and management handbooks were adapted to manage programmatic, technical, schedule, cost elements and risk. As the EV-1 missions are nearly at the end of their successful execution and project lifecycle and the submission deadline of the next mission proposals near, the ESSP PO is taking the lessons learned and updated the programmatic management approach for all future Earth Venture Suborbital (EVS) missions for an even more flexible and streamlined management approach.

    Airborne real time observation are a major component of NASA's Earth Science research and satellite ground validation studies. For mission scientist, planning a research aircraft mission within the context of meeting the science objective is a complex task because it requires real time situational awareness of the weather conditions that affect the aircraft track. Multiple aircraft are often involved in the NASA field campaigns the coordination of the aircraft with satellite overpasses, other airplanes and the constantly evolving dynamic weather conditions often determine the success of the campaign. A flight planning tool is needed to provide situational awareness information to the mission scientist and help them plan and modify the flight tracks successfully. Scientists at the University of Alabama Huntsville and the NASA Marshal Space Flight Center developed the Waypoint Planning Tool (WPT), an interactive software tool that enables scientist to develop their own flight plans (also known as waypoints), with point and click mouse capabilities on a digital map filled with time raster and vector data. The development of this Waypoint Planning Tool demonstrates the significance of mission support in responding to the challenges presented during NASA field campaigns. Analyses during and after each campaign helped identify both issues and new requirements, initiating the next wave of development. Currently the Waypoint Planning Tool has gone through three rounds of development and analysis processes. The development of this waypoint tool is directly affected by the technology advances on GIS/Mapping technologies. From the standalone Google Earth application and simple KML functionalities to the Google Earth Plugin and Java Web Start/Applet on web platform, as well as to the rising open source GIS tools with new JavaScript frameworks, the Waypoint planning Tool has entered its third phase of technology advancement. The newly innovated, cross-platform, modular designed

    NASA Earth science research utilizes both spaceborne and airborne real time observations in the planning and operations of its field campaigns. The coordination of air and space components is critical to achieve the goals and objectives and ensure the success of an experiment. Spaceborne imagery provides regular and continual coverage of the Earth and it is a significant component in all NASA field experiments. Real time visible and infrared geostationary images from GOES satellites and multi-spectral data from the many elements of the NASA suite of instruments aboard the TRMM, Terra, Aqua, Aura, and other NASA satellites have become norm. Similarly, the NASA Airborne Science Program draws upon a rich pool of instrumented aircraft. The NASA McDonnell Douglas DC-8, Lockheed P3 Orion, DeHavilland Twin Otter, King Air B200, Gulfstream-III are all staples of a NASA's well-stocked, versatile hangar. A key component in many field campaigns is coordinating the aircraft with satellite overpasses, other airplanes and the constantly evolving, dynamic weather conditions. Given the variables involved, developing a good flight plan that meets the objectives of the field experiment can be a challenging and time consuming task. Planning a research aircraft mission within the context of meeting the science objectives is complex task because it is much more than flying from point A to B. Flight plans typically consist of flying a series of transects or involve dynamic path changes when "chasing" a hurricane or forest fire. These aircraft flight plans are typically designed by the mission scientists then verified and implemented by the navigator or pilot. Flight planning can be an arduous task requiring frequent sanity checks by the flight crew. This requires real time situational awareness of the weather conditions that affect the aircraft track. Scientists at the University of Alabama-Huntsville and the NASA Marshall Space Flight Center developed the Waypoint Planning Tool, an

    The ICARTT (International Consortium for Atmospheric Research on Transport and Transformation) file format was recently endorsed by the NASA Earth Science Data Systems Standards Process Group (ESDS SPG) as a standard (ESDS-RFC-019) for specifying airborne-based Earth System Data Records (ESDR). In order to accelerate adoption of the new standard in the airborne science data community, SWIFT (Scanning Web-based ICARTT File Tool) was developed to provide a means for data providers to validate their own originated ICARTT-formatted file before submission to data archival facilities provided by NASA Langley's Atmospheric Science Data Center and the NASA Langley Airborne Science Data for Atmospheric Composition group. SWIFT builds upon a predecessor, a software utility named: FSCAN (File Scan). A major upgrade to FSCAN, the objective of SWIFT is to support all valid ICARTT files and to extract and store the file metadata in an ESDR relational database. The SWIFT-validated search metadata make it possible for COTS software and web applications to leverage the built-in spatial and temporal query capabilities of the relational database and to enable file and parameter sub-setting capabilities, as well as facilitating the generation of airborne science data merge products. These enhancements help to minimize development time of other related web applications and open up opportunities for robust data queries.

    Scientific Ocean drilling has a rich legacy which is largely responsible for our current understating of the complex linkages among the different parts of the Earth System. Relaying these understandings to Earth and ocean educators is a challenge that the Joint Oceanographic Institutes (JOI) Alliances has undertaken through sponsorship of the School of Rock (SOR). Building on the successful ocean-going, hands-on SOR (Leckie et al. 2006), the Integrated Ocean Drilling Program (IODP) - United States Implementing Organization (USIO) piloted a land-based, hands-on research expedition for Earth and ocean science teachers, the School of Rock Expedition II (SOR II). During this seven-day workshop, 18 educators from across the United States were hosted at the IODP Gulf Coast Repository at Texas A&M University where they were mentored and taught by scientists who are actively engaged in IODP research, shipboard technical staff, SOR I veteran teachers, and science educators. Teachers participated in a series of research experiences similar to those that take place on a scientific drilling research vessel or in a post-cruise research lab. These experiences allowed educators to increase their knowledge of IODP and scientific methods as demonstrated by the entire ocean drilling program (proposals, drilling, lab analysis, data acquisition, and post-cruise research). This case study describes the formal and informal partnerships developed through the SOR II with an emphasis on identifying and nurturing informal partnerships.

    The Stratospheric Observatory for Infrared Astronomy (SOFIA) is an airborne observatory for astronomical observations at wavelengths ranging from 0.3-1600 µm. It consists of a telescope with an effective aperture of 2.5 m, which is mounted in a heavily modified Boeing 747SP. The aircraft features an open port cavity that gives the telescope an unobstructed view of the sky. Hence the optical system is subject to both aerodynamic loads from airflow entering the cavity, and to inertial loads introduced by motion of the airborne platform. A complex suspension assembly was designed to stabilize the telescope. Detailed end-to-end simulations were performed to estimate image stability based on the mechatronic design, the expected loads, and optical influence parameters. In December 2010 SOFIA entered its operational phase with a series of Early Science flights, which have relaxed image quality requirements compared to the full operations capability. At the same time, those flights are used to characterize image quality and image stability in order to validate models and to optimize systems. Optimization of systems is not based on analytical models, but on models derived from system identification measurements that are performed on the actual hardware both under controlled conditions and operational conditions. This paper discusses recent results from system identification measurements, improvements to image stability, and plans for the further enhancement of the system.

    Jorge Juan and Antonio de Ulloa, naval officers of the Spanish Navy in the Midshipmen's Royal Academy were appointed to take part in one of the most important scientific expeditions of the 18th century. The question of the shape of the Earth, of vital importance for navigation, was solved by the Paris Academy of Sciences by request of Louis XV of France in 1735. The aim was to determine the form of the ellipsoid that Newton had described in the 17th century for any spherical and homogeneous body in rotation about an axis. Two expeditions were prepared for the geodetic measures of meridian arc both in high latitudes (Lapland, Finland) and in the equatorial zone (the Kingdom of Peru); Pierre Louis Maupertuis took charge of the northern expedition whereas the second one was charged to La Condamine, along with Jorge Juan and Antonio de Ulloa. The results obtained by the Spaniards were gathered in a publication: Observaciones astronómicas y físicas hechas en los Reinos del Perú. In it, they dedicate a chapter to the determination of astronomic longitude with the only technology that was providing certain precision at the moment: the simultaneous observation of the same astronomic phenomenon in two different places. Specifically, they explain in detail in Book III: Las Observaciones de la Inmersiones y Emersiones de los satélites de Júpiter, como asimismo de los eclipses de Luna; de las cuales de deduce la Longitud de los Lugares, incluyendo las correcciones a efectuar por la variación de la declinación diaria del Sol.

    EarthLabs, an exemplary series of lab-based climate science learning modules, is a model for high school Earth Science lab courses. Each module includes a variety of learning activities that allow students to explore the Earth's complex and dynamic climate history. The most recent module, Climate Detectives, uses data from IODP Expedition 341, which traveled to the Gulf of Alaska during the summer of 2013 to study past climate, sedimentation, and tectonics along the continental margin. At the onset of Climate Detectives, students are presented with a challenge engaging them to investigate how the Earth's climate has changed since the Miocene in southern Alaska. To complete this challenge, students join Exp. 341 to collect and examine sediments collected from beneath the seafloor. The two-week module consists of six labs that provide students with the content and skills needed to solve this climate mystery. Students discover how an international team collaborates to examine a scientific problem with the IODP, compete in an engineering design challenge to learn about scientific ocean drilling, and learn about how different types of proxy data are used to detect changes in Earth's climate. The NGSS Science and Engineering Practices are woven into the culminating activity, giving students the opportunity to think and act like scientists as they investigate the following questions: 1) How have environmental conditions in in the Gulf of Alaska changed during the time when the sediments in core U1417 were deposited? (2) What does the occurrence of different types of diatoms and their abundance reveal about the timing of the cycles of glacial advance and retreat? (3) What timeline is represented by the section of core? (4) How do results from the Gulf of Alaska compare with the global record of glaciations during this period based on oxygen isotopes proxies? Developed by educators in collaboration with Expedition 341 scientists, Climate Detectives is a strong example of

    The 2009 Arctic Mars Analog Svalbard Expedition (AMASE) investigated several geologic settings using methodologies and techniques being developed or considered for future Mars missions, such as the Mars Science Laboratory (MSL), ExoMars, and Mars Sample Return (MSR). AMASE-related research comprises both analyses conducted during the expedition and further analyses of collected samples using laboratory facilities at a variety of institutions. The Sample Analysis at Mars (SAM) instrument suite, which will be part of the Analytical Laboratory on MSL, consists of a quadrupole mass spectrometer (QMS), a gas chromatograph (GC), and a tunable laser spectrometer (TLS). An Evolved Gas Analysis Mass Spectrometer (EGA-MS) was used during AMASE to represent part of the capabilities of SAM. The other instrument included in the MSL Analytical Laboratory is CheMin, which uses X-Ray Diffraction (XRD) and X-Ray Fluorescence (XRF) to perform quantitative mineralogical characterization of samples. Field-portable versions of CheMin were used during the AMASE 2009. Here, we discuss the preliminary interpretation of EGA and XRD analyses of selected AMASE carbonate samples and implications for mineralogical interpretations from MSL. Though CheMin will be the primary mineralogical tool on MSL, SAM EGA could be used to support XRD identifications or indicate the presence of volatile-bearing minerals which may be near or below XRD detection limits. Data collected with instruments in the field and in comparable laboratory setups (e.g., the SAM breadboard) will be discussed.

    The emergence of airborne astronomy in the early twentieth century is recounted. The aerial expedition to observe the solar eclipse on September 10, 1923, is described. Observation of the total solar eclipse of January 24, 1925, is discussed. The Honey Lake aerial expedition to study the solar eclipse of April 28, 1930, is also described. Four major accomplishments in airborne astronomy during the period 1920 to 1930 are listed. Airborne expeditions were undertaken at every logical opportunity, starting a continuous sequence of airborne astronomical expeditions which was to remain unbroken, except by World War II, to the present day. Although the scientific returns of the first ten years were modest, they did exist. Interest in, and support for, airborne astronomy was generated not only among astronomers but also among the public. Albert Stevens, arguably the true father of airborne astronomy, was to become interested in applying his considerable skill and experience to the airborne acquisition of astronomical data.

    Multi-instrument aircraft-based science campaigns require a baseline level of housekeeping service to record and distribute real time data, including timing signals, aircraft state and air data. As campaigns have become more sophisticated with greater integration between aircraft, ground instrumentation, satellites and forecasters in locations around the world, the scope of the services provided by the facility data systems on NASA's airborne science aircraft have increased to include situational awareness displays, real-time interchange of data between instruments and aircraft, and ingest of data to assist in real-time targeting of flights. As the scope of services has expanded, it has become increasingly important to provide standardized interfaces to experimenters to minimize integration complexity, and to make services sufficiently reliable for mission operations to depend upon them. Within the NASA airborne science program in recent years this has been provided by systems based around the core of the REVEAL/NASDAT system, with additional services including satellite communications, data display and ingest of outside data being provided by a mix of custom and COTS hardware and software. With a strong emphasis on transmission of data over industry standard IP and ethernet based networks, this system has been proven on numerous highly diverse missions on the DC-8 over the last 4 years and is being replicated on other NASA Airborne Science Platforms.

    During observation flights the telescope structure of the Stratospheric Observatory for Infrared Astronomy (SOFIA) is subject to disturbance excitations over a wide frequency band. The sources can be separated into two groups: inertial excitation caused by vibration of the airborne platform, and aerodynamic excitation that acts on the telescope assembly (TA) through an open port cavity. These disturbance sources constitute a major difference of SOFIA to other ground based and space observatories and achieving the required pointing accuracy of 1 arcsecond cumulative rms or better below 70 Hz in this environment is driving the design of the TA pointing and control system. In the current design it consists of two parts, the rigid body attitude control system and a feed forward based compensator of flexible TA deformation. This paper discusses the characterization and control system tuning of the as-built system. It is a process that integrates the study of the structural dynamic behavior of the TA, the resulting image motion in the focal plane, and the design and implementation of active control systems. Ground tests, which are performed under controlled experimental conditions, and in-flight characterization tests, both leading up to the early science performance capabilities of the observatory, are addressed.

    NASA's Jet Propulsion Laboratory is currently building a reconfigurable, polarimetric L-band synthetic aperture radar (SAR), specifically designed to acquire airborne repeat track SAR data for differential interferometric measurements. Differentian interferometry can provide key deformation measurements, important for studies of earthquakes, volcanoes and other dynamically changing phenomena. Using precision real-time GPS and a sensor controlled flight management system, the system will be able to fly predefined paths with great precision. The expected performance of the flight control system will constrain the flight path to be within a 10 m diameter tube about the desired flight track. The radar will be designed to be operable on a UAV (Unpiloted Aria1 Vehicle) but will initially be demonstrated on a NASA Gulfstream III. The radar will be fully polarimetric, with a range bandwidth of 80 MHz (2 m range resolution), and will support a 16 km range swath. The antenna will be electronically steered along track to assure that the antenna beam can be directed independently, regardless of the wind direction and speed. Other features supported by the antenna include elevation monopulse and pulse-to-pulse re-steering capabilities that will enable some novel modes of operation. The system will nominally operate at 45,000 ft (13800 m). The program began as an Instrument Incubator Project (IIP) funded by NASA Earth Science and Technology Office (ESTO).

    The Earth Science Data Systems Working Groups (ESDSWG) were setup by NASA HQ 10 years ago. The role of the ESDSWG is to make recommendations relevant to NASA's Earth science data systems from users experiences. Each group works independently focussing on a unique topic. Participation in ESDSWG groups comes from a variety of NASA-funded science and technology projects, NASA information technology experts, affiliated contractor staff and other interested community members from academia and industry. Recommendations from the ESDSWG groups will enhance NASA's efforts to develop long term data products. The ASCII for Science Data Working Group (WG) will define a minimum set of information that should be included in ASCII file headers so that the users will be able to access the data using only the header information. After reviewing various use cases, such as field data and ASCII data exported from software tools, and reviewing ASCII data guidelines documentation, this WG will deliver guidelines for creating ASCII files that contain enough header information to allow the user to access the science data. The Airborne WG's goal is to improve airborne data access and use for NASA science. The first step is to evaluate the state of airborne data and make recommendations focusing on data delivery to the DAACs (data centers). The long term goal is to improve airborne data use for Earth Science research. Many data aircraft observations are reported in ASCII format. The ASCII and Airborne WGs seem like the same group, but the Airborne WG is concerned with maintaining and using airborne for science research, not just the data format. The Geospatial WG focus is on the interoperability issues of Geospatial Information System (GIS) and remotely sensed data, in particular, focusing on DAAC(s) data from NASA's Earth Science Enterprise. This WG will provide a set of tools (GIS libraries) to use with training and/or cookbooks through the use of Open Source technologies. A progress

    The Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on the Terra spacecraft offers near real-time data delivery through an expedited system used to support emergency responders and science field campaigns. Data acquired and processed in this manner can be available for download within six hours of collection, as compared with a lag time of many days before standard products become available at two distribution sites. The orbit revisit frequency is 16 days for nadir views, but this can be reduced substantially through off-nadir pointing, at high latitudes, and by night observations. Scheduling confirmation takes place two to four days prior to imaging. ASTER is a joint mission involving the U.S. and Japan. ASTER expedited data are generated at the Land Processes Distributed Active Archive Center (LP DAAC), where standard products are also archived after receipt from affiliates at the Earth Remote Sensing Data Analysis Center (ERSDAC) in Tokyo. The ASTER instrument operates through scheduled observations, and is very successfully completing a global mapping mission. With three visible and near-infrared (VNIR) bands at 15 m ground resolution, six shortwave infrared (SWIR) bands at 30 m resolution, and five thermal infrared (TIR) bands at 90 m resolution, the 1.7-million scene archive of ASTER data acquired during the last decade provides utility in a wide range of investigations. A back-looking band is also present that enables the generation of digital elevation models (DEM). ASTER expedited data have been requested by national and international emergency response organizations to provide current views of many types of disaster situations, including volcanoes, hurricanes, wildfires, floods, tsunamis, landslides and other events. ASTER data have been provided in response to activations of the International Charter, Space and Major Disasters. Examples of data acquired for a variety of disaster situations will be provided.

    2012-01-01

    The 2011 Arctic Mars Analog Svalbard Expedition (AMASE) investigated several geologic settings on Svalbard, using methodologies and techniques being developed or considered for future Mars missions, such as the Mars Science Laboratory (MSL). The Sample Analysis at Mars (SAM) instrument suite on MSL consists of a quadrupole mass spectrometer (QMS), a gas chromatograph (GC), and a tunable laser spectrometer (TLS), which analyze gases created by pyrolysis of samples. During AMASE, a Hiden Evolved Gas Analysis-Mass Spectrometer (EGA-MS) system represented the EGA-QMS capability of SAM. Another MSL instrument, CheMin, will use x-ray diffraction (XRD) and x-ray fluorescence (XRF) to perform quantitative mineralogical characterization of samples. Field-portable versions of CheMin were used during AMASE. AMASE 2011 sites spanned a range of environments relevant to understanding martian surface materials, processes and habitability. They included the basaltic Sverrefjell volcano, which hosts carbonate globules, cements and coatings, carbonate and sulfate units at Colletth0gda, Devonian sandstone redbeds in Bockfjorden, altered basaltic lava delta deposits at Mt. Scott Keltie, and altered dolerites and volcanics at Botniahalvoya. Here we focus on SAM-like EGA-MS of a subset of the samples, with mineralogy comparisons to CheMin team results. The results allow insight into sample organic content as well as some constraints on sample mineralogy.

    Surface science research fixated on phenomena and processes that transpire at the electrode-electrolyte interface has been pursued in the past. A considerable proportion of the earlier work was on materials and reactions pertinent to the operation of small-molecule fuel cells. The experimental approach integrated a handful of surface-sensitive physical-analytical methods with traditional electrochemical techniques, all harbored in a single environment-controlled electrochemistry-surface science apparatus (EC-SSA); the catalyst samples were typically precious noble metals constituted of well-defined single-crystal surfaces. More recently, attention has been diverted from fuel-to-energy generation to its converse, (solar) energy-to-fuel transformation; e.g., instead of water synthesis (from hydrogen and oxygen) in fuel cells, water decomposition (to hydrogen and oxygen) in artificial photosynthesis. The rigorous surface-science protocols remain unchanged but the experimental capabilities have been expanded by the addition of several characterization techniques, either as EC-SSA components or as stand-alone instruments. The present manuscript describes results selected from on-going studies of earth-abundant electrocatalysts for the reactions that underpin artificial photosynthesis: nickel-molybdenum alloys for the hydrogen evolution reaction, calcium birnessite as a heterogeneous analogue for the oxygen-evolving complex in natural photosynthesis, and single-crystalline copper in relation to the carbon dioxide reduction reaction.

  9. Inter-Comparison of Ozone and Aerosol Observations During the NCAS Trans-Atlantic Saharan Dust Aerosol and Ocean Science Expedition

    2005-12-01

    The NOAA Center for Atmospheric Sciences (NCAS) conducted a combined atmospheric and oceanographic experiment aboard the NOAA Ronald H. Brown ship to characterize the physico-chemical evolution of the Saharan Aerosol Layer during its long-range transport into the eastern seaboard of the United States and the Caribbean and to quantify its effects on the regional environment and climate. The NCAS Trans-Atlantic Aerosol and Oceanographic Science Expedition (AEROSE-04) departed on its 27-day voyage February 29, 2004 from Bridgetown, Barbados and concluded in San Juan, Puerto Rico on March 26, 2004. During AEROSE-04, several atmospheric constituents were measured to study the effects of Saharan dust on the chemistry of the atmospheric environment. Surface level measurements of ozone were obtained on an hourly basis along with aerosol number density during several dust storms that occurred during the cruise. Inter-comparisons between the ozone and aerosol number density datasets enable an evaluation of the behavior of ozone during dust storms. Ozone concentrations were generally observed to decrease during the dust storm. However this decrease in ozone was not always observed to be inversely proportional with daytime aerosol number density measurements. This indicates that an increase in aerosol optical depth above the marine boundary layer is not the sole mechanism involved in ozone depletion. We will present a detailed analysis of the ozone-aerosol relationships as a function of aerosol number density, aerosol surface area, and aerosol composition with the objective of evaluating the role of aerosol chemistry in the ozone depletion process.

    The publication records from NASA's airborne observatories are examined to evaluate the contribution of the airborne astronomy program to technological development and scientific/educational progress. The breadth and continuity of program is detailed with reference to its publication history, discipline representation, literature citations, and to the ability of such a program to address nonrecurring and unexpected astronomical phenomena. Community involvement in the airborne-observation program is described in terms of the number of participants, institutional affiliation, and geographic distribution. The program utilizes instruments including heterodyne and grating spectrometers, high-speed photometers, and Fabry-Perot spectrometers with wide total spectral ranges, resolutions, and numbers of channels. The potential of the program for both astronomical training and further scientific, theoretical, and applied development is underscored.

    2014-12-01

    NASA has conducted airborne tropospheric chemistry studies for about three decades. These field campaigns have generated a great wealth of observations, which are characterized by a wide range of trace gases and aerosol properties. The airborne observational data have often been used in assessment and validation of models and satellite instruments. One particular issue is a lack of consistent variable naming across field campaigns, which makes cross-mission data discovery difficult. The ASDC Toolset for Airborne Data (TAD) is being designed to meet the user community needs for manipulating aircraft data for scientific research on climate change and air quality relevant issues. As part of this effort, a common naming system was developed to provide a link between variables from different aircraft field studies. This system covers all current and past airborne in-situ measurements housed at the ASDC, as well as select NOAA missions. The TAD common variable naming system consists of 6 categories and 3 sub-levels. The top-level category is primarily defined by the physical characteristics of the measurement: e.g., aerosol, cloud, trace gases. The sub-levels were designed to organize the variables according to nature of measurement (e.g., aerosol microphysical and optical properties) or chemical structures (e.g., carbon compound). The development of the TAD common variable naming system was in consultation with staff from the Global Change Master Directory (GCMD) and referenced/expanded the existing Climate and Forecast (CF) variable naming conventions. The detailed structure of the TAD common variable naming convention and its application in TAD development will be presented.

    NASA has conducted airborne tropospheric chemistry studies for about three decades. These field campaigns have generated a great wealth of observations, which are characterized by a wide range of trace gases and aerosol properties. The airborne observational data have often been used in assessment and validation of models and satellite instruments. The ASDC Toolset for Airborne Data (TAD) is being designed to meet the user community needs for manipulating aircraft data for scientific research on climate change and air quality relevant issues. Given the sheer volume of data variables across field campaigns and instruments reporting data on different time scales, this data is often difficult and time-intensive for researchers to analyze. The TAD web application is designed to provide an intuitive user interface (UI) to facilitate quick and efficient discovery from a vast number of airborne variables and data. Users are given the option to search based on high-level parameter groups, individual common names, mission and platform, as well as date ranges. Experienced users can immediately filter by keyword using the global search option. Once the user has chosen their required variables, they are given the option to either request PI data files based on their search criteria or create merged data, i.e. geo-located data from one or more measurement PIs. The purpose of the merged data feature is to allow users to compare data from one flight, as not all data from each flight is taken on the same time scale. Time bases can be continuous or based on the time base from one of the measurement time scales and intervals. After an order is submitted and processed, an ASDC email is sent to the user with a link for data download. The TAD user interface design, application architecture, and proposed future enhancements will be presented.

    The Arctic Mars Analog Svalbard Expeditions (AMASE) have investigated a range of geologic settings on Svalbard, using methodologies and techniques being developed for Mars missions, such as the Mars Science Laboratory (MSL). The Sample Analysis at Mars (SAM) instrument suite on MSL consists of a quadrupole mass spectrometer (QMS), a gas chromatograph (GC), and a tunable laser spectrometer (TLS), which analyze gases created by pyrolysis of samples. During AMASE, a Hiden Evolved Gas Analysis-Mass Spectrometer (EGA-QMS) system represented the EGA-QMS capability of SAM. Another MSL instrument, CheMin, will use x-ray diffraction (XRD) and x-ray fluorescence (XRF) to perform quantitative mineralogical characterization of samples. Field-portable versions of CheMin were used during AMASE. Here we discuss the SAM-like EGA-QMS analyses of a selected subset of samples acquired during several field seasons, together with AMASE CheMin team results. The results enable insight into organic content, organic-mineral associations, and mineralogy. Organic materials evolved from all samples over a range of temperatures. In general, this can indicate that the organics have a range of thermal maturity and/or are bound in different ways to their matrix. Most often, organics that were outside of mineral grains were the dominant pool of organic material inferable from the EGA-QMS, but organics encapsulated within mineral grains, including possibly methane, were also inferred. Organic-mineral associations can influence organic preservation potential and detection. Constraints on these associations, and overall sample organic chemistry, enabled by our SAM-like EGA-QMS analog analyses demonstrate the potential to understand the organic chemical characteristics in materials sampled by MSL, even when utilizing EGA-QMS, the simplest type of solid sample experiment SAM will perform. Any organic chemical information inferred from EGA-QMS analysis could then also be followed by detailed SAM EGA

    1990-01-01

    In situ airborne measurements of turbulent heat, moisture, momentum, ozone, and carbon monoxide fluxes in a convective boundary layer were obtained over a tropical rain forest between 1100 and 1630 LT on May 4, 1987. The aircraft flight path was chosen so as to fly over the tower site at the Ducke Forest Reserve near Manaus, Amazonas, Brazil. Both turbulence statistics and mean quantities were used to study the budgets of heat, water vapor, ozone, and carbon monoxide. The ozone budget study shows an accumulation rate in the boundary layer of 0.3 + or - 0.2 ppbv/h. The surface resistance to ozone during this flight was determined to be 0.06 + or - 0.03 s/cm, while the aerodynamic resistance was 0.14-0.17 s/cm. Results from the CO budget analysis show a midday accumulation rate of 0.6 + or - 0.3 ppbv/h in the Amazonian boundary layer. The evidence suggests production of CO in the PBL. A source of CO may exist below the lowest flight level (about 150 m), although it was not possible to determine what part of the flux at flight level was due to chemical production and what part may be due to surface emission.

    Advanced exploration and development in harsh environments require mastery of basic human survival skill. Expeditions into the lethal climates of Earth's polar regions offer useful lessons for tommorrow's lunar pioneers. In Arctic and Antarctic exploration, 'wintering over' was a crucial milestone. The ability to establish a supply base and survive months of polar cold and darkness made extensive travel and exploration possible. Because of the possibility of near-constant solar illumination, the lunar polar regions, unlike Earth's may offer the most hospitable site for habitation. The World Space Foundation is examining a scenario for establishing a five-person expeditionary team on the lunar north pole for one year. This paper is a status report on a point design addressing site selection, transportation, power, and life support requirements.

    It is critical to the future success of the scientific workforce that we understand, investigate and implement new strategies to engage a more diverse range of youth in STEM activities and the excitement of science through a variety of less traditional avenues. Here we present the underlying design principles and outcomes of a series of front-end tests of the AstroTrek: Astronomical Learning Expeditions program. This program is designed to broaden the range of teenagers who choose to take part in science learning outside of school, and diversify the gateways through which they can be engaged in and excited by science; develop contexts and strategies where we can bring youth from where they are to where we (the scientific community) are; and find strategies to include authentic scientific experiences in expeditionary learning taking the experiences beyond ‘science tourism’.

    The Spectrometers for Sky-Scanning, Sun-Tracking Atmospheric Research (4STAR) instrument has been developed at NASA Ames in collaboration with Pacific Northwest National Laboratory (PNNL) and NASA Goddard, supported substantially since 2009 by NASA's Radiation Science Program and Earth Science Technology Office. It combines grating spectrometers with fiber optic links to a tracking, scanning head to enable sun tracking, sky scanning, and zenith viewing. 4STAR builds on the long and productive heritage of the NASA Ames Airborne Tracking Sunphotometers (AATS-6 and -14), which have yielded more than 100 peer-reviewed publications and extensive archived data sets in many NASA Airborne Science campaigns from 1986 to the present. The baseline 4STAR instrument has provided extensive data supporting the TCAP (Two Column Aerosol Project, July 2012 & Feb. 2013), SEAC4RS (Studies of Emissions, Atmospheric Composition, Clouds and Climate Coupling by Regional Surveys, 2013), and ARISE (Arctic Radiation - IceBridge Sea and Ice Experiment, 2014), field campaigns.This poster presents plans and progress for an upgrade to the 4STAR instrument to achieve full science capability, including (1) direct-beam sun tracking measurements to derive aerosol optical depth spectra, (2) sky radiance measurements to retrieve aerosol absorption and type (via complex refractive index and mode-resolved size distribution), (3) cloud properties via zenith radiance, and (4) trace gas spectrometry. Technical progress in context with the governing physics is reported on several upgrades directed at improved light collection and usage, particularly as related to spectrally and radiometrically stable propagation through the collection light path. In addition, improvements to field calibration and verification, and flight operability and reliability are addressed.

    Atmospheric temperatures are warming faster in the Arctic than predicted by climate models. The impact of this warming on permafrost degradation is not well understood, but it is projected to increase carbon decomposition and greenhouse gas production (CO₂ and/or CH₄) by arctic ecosystems. Airborne observations of atmospheric trace gases, aerosols, and cloud properties at the North Slope of Alaska are improving our understanding of global climate, with the goal of reducing the uncertainty in global and regional climate simulations and projections.

    The objectives of this task in the AITT (Airborne Instrument Technology Transition) Program are to (1) upgrade the NASA 4STAR (Spectrometer for Sky-Scanning, Sun-Tracking Atmospheric Research) instrument to its full science capability of measuring (a) direct-beam sun transmission to derive aerosol optical depth spectra, (b) sky radiance vs scattering angle to retrieve aerosol absorption and type (via complex refractive index spectra, shape, and mode-resolved size distribution), (c) zenith radiance for cloud properties, and (d) hyperspectral signals for trace gas retrievals, and (2) demonstrate its suitability for deployment in challenging NASA airborne multiinstrument campaigns. 4STAR combines airborne sun tracking, sky scanning, and zenith pointing with diffraction spectroscopy to improve knowledge of atmospheric constituents and their links to air pollution, radiant energy budgets (hence climate), and remote measurements of Earth's surfaces. Direct beam hyperspectral measurement of optical depth improves retrievals of gas constituents and determination of aerosol properties. Sky scanning enhances retrievals of aerosol type and size distribution. 4STAR measurements are intended to tighten the closure between satellite and ground-based measurements. 4STAR incorporates a modular sun-tracking/sky-scanning optical head with fiber optic signal transmission to rack mounted spectrometers, permitting miniaturization of the external optical head, and future detector evolution. 4STAR test flights, as well as science flights in the 2012-13 TCAP (Two-Column Aerosol Project) and 2013 SEAC4RS (Studies of Emissions and Atmospheric Composition, Clouds and Climate Coupling by Regional Surveys) have demonstrated that the following are essential for 4STAR to achieve its full science potential: (1) Calibration stability for both direct-beam irradiance and sky radiance, (2) Improved light collection and usage, and (3) Improved flight operability and reliability.

    Nowhere on Earth is warming faster than the Arctic. In northern Siberia, average temperatures have risen 3-5 deg F over the past 30 years, whereas the worldwide average increase in that time is 1 deg F. Betweeen July 28 and August 12, 2007, a small international team of remote sensing and forest ecosystem scientists from NASA and Russia's Academy of Science set off on a three-week scientific expedition through the heart of the remote, wild forests of Siberia. They traveled southward down the Kochechum River observing the gradual transition from tundra to taiga, taking inventory of plant species along the way, and making ground-truth measurements to validate data being collected by several NASA satellites flying 700 kilometers overhead.

    2015-04-01

    2012 marked the 100st anniversary of the seminal publications on Continental Drift Theory by Alfred Wegener. These publications (and Wegener's book "On the origin of the continents", published three years later) are widely accepted to be the fundamental breakthrough that opened the path to the Theory of Plate Tectoncis and ultimately the path to modern Geodynamics some 50 years later. In the same historic year of the 1912 publications, Alfred Wegener set off for what was to become the most dramatic of his three Greenland expeditions. On this expedition Wegener and Koch crossed the entire northern icecap of Greenland. In honour of the hundreds anniversary of Wegener's publications, the Austrian Academy of Sciences funded an expedition to trace the footsteps of the 1912 expedition in the spirit of Alfred Wegener, while also conducting modern Earth Science. This expedition that was conducted in summer 2014. For the expedition, a 1952 Cessna180 was acquired in Alaska, adapted with bush wheels, wing extensions and extra tanks and was flown by the author and one of the worlds most renown bush pilots from Alaska in a 10 day effort to Greenland. There, the entire NE Greenland Caledonides were covered and photographed. Field work for a masters projects was conducted and samples were collected from a series of some of the most remote locations in the Caledonides ever visited. Most spectacularly, the original sled of Wegeners 1912 expedition was found some 30 kilometers from its expected location in the Dove Bugt Region of northeastern Greenland.

    The origins of the North German expeditions to observe the total solar eclipse of August 18, 1868, are outlined. The incentive was made by politician and science writer Aaron Bernstein, the financing was provided by the North German Federation, and the project was handled by members of the Astronomische Gesellschaft. The astronomical expeditions to Mulwar in India and Aden in South Arabia are summarized, the following archaeological expedition to upper Egypt is also considered. The activities of the participating scientists, also with respect to the preparation of popular accounts, are described. Finally, the impact of these expeditions on the planning of the large-scale project to observe the Venus transits of 1874 and 1882 is investigated.

    2006-01-01

    The 2005 expedition to the Haughton-Mars Project (HMP) research station on Devon Island was part of a NASA-funded project on Space Logistics. A team of nine r&searchers from MIT went to the Canadian Arctic to participate in the annual I-IMP field campaign from July 8 to August 12, 2005. We investigated the applicability of the HMP research station as an analogue for planetary macro- and micro-logistics to the Moon and Mars, and began collecting data for modeling purposes. We also tested new technologies and procedures to enhance the ability of humans and robots to jointly explore remote environments. The expedition had four main objectives. We briefly summarize our key findings in each of these areas. 1. Classes of Supply: First, we wanted to understand what supply items existed at the HMP research station in support of planetary science and exploration research at and around the Haughton Crater. We also wanted to quantify the total amount of imported mass at HMP and compare this with predictions from existing parametric lunar base demand models. 2. Macro-Logistics Transportation Network: Our second objective was to understand the nodes, transportation routes, vehicles, capacities and crew and cargo mass flow rates required to support the HMP logistics network. 3. Agent and Asset Tracking: Since the current inventory management system on ISS relies heavily on barcodes and manual tracking, we wanted to test new automated technologies and procedures such as radio frequency identification RFID) to support exploration logistics. 4. Micro-Logistics (EVA): Finally, we wanted to understand the micro-logistical requirements of conducting both short (<1 day) and long traverses in the Mars-analog terrain on Devon Island. Micro-logistics involves the movement of surface vehicles, people and supplies from base to various exploration sites over short distances (<100 km).

  7. Gender, culture, and astrophysical fieldwork: Elizabeth Campbell and the Lick Observatory-Crocker eclipse expeditions.

    NASA Astrophysics Data System (ADS)

    Pang, A. S.-K.

    The article is organized as follows. It begins with an overview of women in nineteenth-century American science. It then describes the culture of mountaintop observatories and life on Mount Hamilton. Elizabeth Campbell's unique role in the Crocker-Lick expeditions drew upon her equally unique role in the observatory, and also on the meaning given to women's work in general on the mountain. The bulk of the article focuses on the Campbells and their expeditions to India in 1898, Spain in 1905, and the South Pacific in 1908. The third section compares the Lick Observatory expeditions to those conducted by David Todd of Amherst College. Todd's wife, Mabel Loomis Todd, went into the field several times with her husband, but her place in the field was radically different from Elizabeth Campbell's, a difference that can be ascribed to a combination of local culture and personality. Finally, it compares American expeditions to British expeditions of the period, to see what the absence of British women on expeditions can tell us about the way national scientific styles and cultures affected gender roles in science.

    From February to May 2014, NOAA Ship Okeanos Explorer conducted a telepresence-enabled ocean exploration expedition addressing NOAA and National deepwater priorities in the U.S. Gulf of Mexico. The community-driven expedition connected diverse and geographically dispersed audiences including scientists from industry, academia, and government, and educators, students, and the general public. Expedition planning included input from the ocean science and management community, and was executed with more than 70 scientists and students from 14 U.S. states participating from shore in real time. Training the next generation permeated operations: a mapping internship program trained undergraduate and graduate students; an ROV mentorship program trained young engineers to design, build and operate the system; and undergraduate through doctoral students around the country collaborated with expedition scientists via telepresence. Online coverage of the expedition included background materials, daily updates, and mission logs that received more than 100,000 visits by the public. Live video feeds of operations received more than 700,000 views online. Additionally, professional development workshops hosted in multiple locations throughout the spring introduced educators to the Okeanos Explorer Educational Materials Collection and the live expedition, and taught them how to use the website and education resources in their classrooms. Social media furthered the reach of the expedition to new audiences, garnered thousands of new followers and provided another medium for real-time interactions with the general public. Outreach continued through live interactions with museums and aquariums, Exploration Command Center tours, outreach conducted by partners, and media coverage in more than 190 outlets in the U.S. and Europe. Ship tours were conducted when the ship came in to port to engage local scientists, ocean managers, and educators. After the expedition, data and products were

    A total eclipse swept across Queensland and other sites in northeastern Australia on the early morning of 14 November 2012, local time. We mounted equipment to observe coronal images and spectra during the approximately 2 minutes of totality, the former for comparison with spacecraft images and to fill in the doughnut of imaging not well covered with space coronagraphs. Matching weather statistics, viewing was spotty, and our best observations were from a last-minute inland site on the Tablelands, with some observations from a helicopter at 9000 feet altitude over our original viewing site at Miallo. Only glimpses of the corona were visible at our Port Douglas and Trinity Beach, Cairns, locations, with totality obscured from our sites at Newell and Miallo, though some holes in the clouds provided coronal views from Palm Cove and elsewhere along the coast. Preliminary analysis of the spectra again shows Fe XIV stronger than Fe X, as in 2010 but not earlier, a sign of solar maximum, as was the coronal shape. An intriguing CME is discernible in the SE.

    2009-01-01

    Revolutionary France's two Pacific expeditions, under the command of Jean-Antoine Bruny d'Entrecasteaux (1792-94) and Nicolas Baudin (1801-1804), demonstrate the importance of scientific inquiry to the newly sovereign nation. France's scientific community adapted to the changed circumstances of revolutionary upheaval by describing its work in terms of national priorities. Individuals on board the expeditions, both naval and scientific personnel, behaved as scientific citizens, intent on composing an encyclopedic body of knowledge about the Pacific. Disputes over whose science mattered more and how credit should be assigned through publication, however, broke down the consensus that science should be a national project.

  7. The Wegener Memorial Expedition to the Greenland Caledonides

    Stüwe, Kurt; Piller, Werner

    2014-05-01

    2012 marked the 100 anniversary of the publication of Alfred Wegeners book: 'Die Entstehung der Kontinente' - which is often hailed as the discovery of continental drift theory in the advent of plate tectonics. Wegener was later appointed as professor for geophysics at the University of Graz in Austria - in part for this discovery. He held this position until his death in Greenland in 1930. In honor of the hundredth anniversary of the 1912 milestone publication, the University of Graz in Austria stages an expedition to Greenland in the spirit of Alfred Wegener, supported by the Austrian Academy of Sciences. The expedition aims predominantly to unravel secrets of the Caledonides of Northeastern Greenland using an extensive sampling program to some of the least explored corners of the orogenic belt. Particular emphasis will be placed on the Hager Bjerg allochthon and its relationship to the hanging wall and footwall units. The expedition will use the unparalleled flexibility of small aircraft that will be piloted by experienced Alaskan bush pilots and brought to Greenland from Alaska for this purpose.

  8. Improved Instrumentation for the Detection of Atmospheric CO2 Concentration using an Airborne IPDA LIDAR for 2014 NASA ASCENDS Science Campaign

    2014-12-01

    NASA-GSFC is developing a twin-channel, Integrated-Path, Differential Absorption (IPDA) lidar to measure atmospheric CO2 from space as a candidate for NASA's ASCENDS mission (Active Sensing of CO2 Emissions over Nights, Days, and Seasons). This lidar consists of two independent, tuned, pulsed transmitters on the same optical bench using a common 8" receiver telescope. The system measures CO2 abundance and O2 surface pressure in the same column to derive the dry volume mixing ratio (vmr). The system is being tested on an airborne platform up to altitudes of 13 Km. The lidar uses a cw scanning laser, externally pulsed and a fiber amplifier in a Master Oscillator Power Amplifier (MOPA) configuration to measure lineshape, range to scattering surfaces and backscatter profiles. The CO2 operates at 1572.335 nm. The O2 channel uses similar technology but frequency doubles to the O2 A-band absorption, around 765nm. Both lasers are scanned across the absorption feature measuring at a fixed number of discrete (~30) wavelengths per scan around ~300 scans/s. Each output pulse is slightly chirped <12MHz as the laser is tuning. Removing this chirp will improve our ability to infer vertical CO2 distribution from a more accurately measured line shape. A Step Tuned Frequency Locked (STFL) DBR diode laser system has been integrated into the CO2 lidar. Tuning and locking takes a ~30μs and the laser is locked to < ±100KHz. We have the ability to position these pulses anywhere on the absorption line other than within a few MHz of line center. While the telescope and fiber coupling scheme remains unchanged the detectors have been upgraded. The O2 system now uses eight SPCMs in parallel to improve count rates and increase dynamic range. Especially useful when flying over bright surfaces. This will improve our ability to measure the O2 pressure at cloud tops and aid in the determining the vmr above clouds.

  9. Expedition Earthscope: A Television Film and DVD

    NASA Astrophysics Data System (ADS)

    Prose, D.; Lamacchia, D.

    2005-12-01

    Independent filmmakers are producing a public television documentary that explores the goals and aspirations of the Earthscope project in the context of what is known and not known about the geology of North America. The unfolding story captures the excitement of the early stages of an historic expedition undertaken by a diverse group of scientists, students, and volunteers, employing the most advanced earth exploration techniques to answer persistent geologic questions about the North American continent. The film documents the efforts of Earthscope scientists as participants in one of the largest coordinated geologic experiments ever, one that promises to deepen our knowledge of the processes, including seismic and volcanic, that have formed the continent and its spectacular landforms. Interspersed with scenes of scientists beginning new Earthscope experiments is archival footage of past experiments, as well as dramatic scenes of earthquakes, volcanic eruptions, landscapes, and cultural activities filmed throughout the US. The film's liberal use of 3D animations helps explain the geologic story and the techniques employed by Earthscope scientists. The purpose of the documentary is to introduce Earthscope and basic earth science concepts to a nationwide audience via PBS broadcasts and distribution to schools, libraries, science centers, and museums. For Earthscope staff, scientists, and educators, the film will be a tool to help educate the public about Earthscope and recruit a diverse mix of young people to take part in the effort. To enhance the usefulness of the film, a companion DVD is also being produced that will include printable ancillary educational resources for use in classrooms and materials that explain the Earthscope project in detail. Pre-release clips from the film will be shown and distribution plans discussed.

    2015-01-01

    Polish expedition to Spitsbergen in 1934 was already the second Polish polar expedition to the Arctic. It was scientific-mountaineering in character. 7 persons took part in it: Witold Biernawski (1898-1957)--film-maker and radiotelegraph operator, Stefan Bernadzikiewicz (1907-1939)--expedition leader, Henryk Mogilnicki (1906-1999)--photographer and radiotelegraph operator, Stefan Zbigniew Różycki (1906-1988)--geologist, Stanisław Siedlecki (1912-2002)--meteorological observer, Sylweriusz Bohdan Zagrajski (1892-1940)--triangulator, Antoni Rogal-Zawadzki (1896-1974)--topographer and photogrammetrist. The purpose of this expedition was to collect data in geology and cartography, and to a lesser degree--in glaciology, botany, zoology and meteorology. It lasted from May 20 to September 16, 1934. The time between June 20 - August 28 the group spent on Spitsbergen's Torell Land. The outcome: an area of app. 300 square kilometres of previously undiscovered land was marked by triangular system, covered by photogrammetric photos and surveyed. Geological research covered the land of app. 500 square kilometres and the group collected geological specimens of app. 800 kg in weight. On the basis of their research, two maps (at a scale of 1:50 000 and 1:200 000) were published. The participants collected also botanical and zoological material. Meteorological observations were carried out at the base over Van Keulen fjord throughout the whole expedition. Different objects on Torell Land were named by the expedition, their names referring largely to Poland (Annex I). Approximately 200 photographs and a film were shot by the expedition. Apart from scientific research, the participants published also diaries of the expedition.

    1993-04-01

    The US Environmental Protection Agency (EPA) and Washington Department of Ecology (Ecology) recommended that the US Department of Energy (DOE) prepare an expedited response action (ERA) for the Riverland Railroad Car Wash Pit and the 600 Area Army Munitions Burial Site. A non-time-critical ERA proposal includes preparation of an engineering evaluation/cost analysis (EE/CA) section. The EE/CA is a rapid, focused evaluation of available technologies using specific screening factors to assess feasibility, appropriateness, and cost. The ERA proposal will undergo reviews by Westinghouse Hanford Company (WHC), DOE, EPA, Ecology, and the public. Ecology and EPA will issue an Action Agreement Memorandum after resolution of all review comments. The, memorandum will authorize remediation activities. The ERA goal is to reduce the potential for any contaminant migration to the soil column, groundwater, and Columbia River. The ERA may be the final remediation of the 100-IU-1 Operable Unit. A No Action Record of Decision may be issued after cleanup completion.

    2005-01-01

    Explorers ranging over kilometers of rugged, sometimes "feature-less" terrain for over a year could be overwhelmed by tracking and sharing what they have done and learned. An automated system based on the existing Mobile Agents design [ I ] and Mars Exploration Rover experience [2], could serve as an "expedition memory" that would be indexed by voice as wel1 as a web interface, linking people, places, activities, records (voice notes, photographs, samples). and a descriptive scientific ontology. This database would be accessible during EVAs by astronauts, annotated by the remote science team, linked to EVA plans, and allow cross indexing between sites and expeditions. We consider the basic problem, our philosophical approach, technical methods, and uses of the expedition memory for facilitating long-term collaboration between Mars crews and Earth support teams. We emphasize that a "memory" does not mean a database per se, but an interactive service that combines different resources, and ultimately could be like a helpful librarian.

    2005-09-01

    Captains Meriwether Lewis and William Clark and other members of their expedition collected and identified nearly 400 species of plants and animals during the Voyage of Discovery. Of this total, 31 species of fish were included in Burrough’s summary of the natural history of the Expedition, including 12 fishes considered unknown to science at that time. While there is little doubt of the identity of fish for which Lewis and Clark provided detailed descriptions in their daily logs, other species designations were largely conjecture based on later scholars interpretation of the Lewis and Clarks account. Unlike other biological specimens encountered during the Expedition, no fishes were brought back for study. As a result, the identity of some fishes was never resolved. Many other fishes were reclassified during the past century based on updated scientific methods.

    The Edge of the Arctic Shelf website communicates scientific results and the beauty of the Arctic Ocean to a broad audience (junior high to PhD). The website supports the physical oceanographic component of the Western Arctic Shelf-Basin Interactions Experiment (SBI), an extensive three-year field program in the Chukchi and Beaufort Seas. The website features four main segments: expedition overview, daily updates, images and facts, and science highlights. Starting this year (2003), I enlisted ten junior high classrooms to participate "virtually" in the cruise. While at sea, I received questions from the students via email. My daily updates incorporated answers to these questions, plus observations and digital photos of the science activities and environment. I then created the html and transmitted the pages to our server. In this fashion, students, scientists, and the general public interacted with our cruise in "near-real-time." This presentation will focus on highlights from the website and lessons learned.

    2010-01-01

    The 1960-1961 Himalayan Scientific and Mountaineering Expedition, commonly known as the Silver Hut Expedition, was a unique project to study the physiology of acclimatization in human lowlander subjects at extreme altitude over a prolonged period and also to make an attempt on Makalu, an 8470-m peak. The leader was Sir Edmund Hillary, and Dr. Griffith Pugh was the scientific leader. Studies were conducted at a Base Camp in the Everest region of Nepal at 4500 m and at the Silver Hut at 5800 m on the Mingbo Glacier. Simpler physiology was continued on Makalu, in camps at 6300 and 7400 m. The expedition left Kathmandu at the end of the monsoon in 1960 and spent the autumn setting up the Base Camp and the Silver Hut. Some members also spent time making a study of the evidence for the existence of the Yeti. The winter was spent on physiological studies at Base Camp and in the Silver Hut, and the nearby peak of Ama Dablam was climbed. In the spring the expedition moved over to Makalu and made an unsuccessful attempt to climb it without supplementary oxygen. The 9-month expedition ended at the start of the 1961 monsoon. An ambitious program of studies was successfully completed. It was a very happy and, scientifically, a successful expedition. Many of the findings were not repeated for many years, and none has been refuted. On the mountaineering side, we were unsuccessful on Makalu owing to a combination of weather and illness, but the ascent of Ama Dablam was considerable compensation.

    A total solar eclipse occurred on March 9 along the path through Indonesia and the Pacific. KASI organized an expedition team for total solar eclipse observation. The main purpose of this observation is to test the coronal temperature and outflow velocity diagnostics based on filter observation, which is proposed for the next generation coronagraph. In addition, various white light observations were tried. Although we could not get satisfactory data for the quantitative diagnostics due to system problem and weather, we could get some useful experimental data and nice white light images. We plan next expedition for 2017 total solar eclipse in USA.

    The International Ocean Discovery Program (IODP) cores sediment and rock below the seafloor during two-month expeditions to study Earth's history and dynamics. Most IODP expeditions sail dedicated education officers to lead outreach efforts, including live ship-to-shore video events. Expeditions conduct 30-90 events through close collaboration between the educators and science party members. In 2014, Expedition 349 collected cores in the South China Sea. Even though no educator sailed, the staff scientist filled this role, allowing the expedition to carry out an extensive program of 58 live events (led by scientists) with institutions in 13 countries, demonstrating that outreach is deeply engrained in IODP culture. Expedition 349 spoke to ~3700 people, including ~375 primary school students in China and the USA, ~1150 secondary school students in six countries, and ~1300 undergraduate and graduate students in seven countries. The scientists also conducted events with museums, science centers, and science conferences. Over the last six years of operations, we have gained significant insights that help us to capitalize on best practices and utilize the newest and most effective technology for live events from sea given bandwidth constraints. We currently conduct video events with an iPad using Zoom software. Educators and scientists work together to provide ship tours and educate audiences about expedition science, lab work, and life at sea, and also answer audience questions. One feature we use extensively is the ability to screen share with Zoom, which allows us to show images stored on the iPad. These images show the location of drill sites and provide background information about the expedition scientific objectives, the drilling and coring process, and more. Shipboard scientists are usually enthusiastic about outreach events and many contact friends and colleagues to schedule additional events. The audiences we connect with ask many great questions and often

    Kozlovskaya, Inessa B.; Egorov, Anatoly D.

    2003-01-01

    Medical support in a Martian expedition will be within the scope of crew responsibilities and maximally autonomous. Requirements to the system of diagnostics in this mission include considerable use of means and methods of visualization of the main physiological parameters, telemedicine, broad usage of biochemical analyses (including "dry" chemistry), computerized collection, measurement, analysis and storage of medical information. The countermeasure system will be based on objective methods of crew fitness and working ability evaluation, individual selection of training regimens, and intensive use of computer controlled training. Implementation of the above principles implies modernization and refinement of the countermeasures currently used by space crews of long-term missions (LTM), and increases of the assortment of active and passive training devices, among them a short-arm centrifuge. The system of medical care with the functions of prevention, clinical diagnostics and timely treatment will be autonomous, too. The general requirements to medical care during the future mission are the following: availability of conditions and means for autonomous urgent and special medical aid and treatment of the most possible states and diseases, "a hospital", and assignment to the crew of one or two doctors. To ensure independence of medical support and medical care in an expedition to Mars an automated expert system needs to be designed and constructed to control the medical situation as a whole. c2003 Published by Elsevier Science Ltd.

    The Airborne Research Experience for Educators (AREE) Program, conducted by the NASA Dryden Flight Research Center Office of Education in partnership with the AERO Institute, NASA Teaching From Space Program, and California State University Fullerton, is a complete end-to-end residential research experience in airborne remote sensing and atmospheric science. The 2009 program engaged ten secondary educators who specialize in science, technology, engineering or mathematics in a 6-week Student Airborne Research Program (SARP) offered through NSERC. Educators participated in collection of in-flight remote sensor data during flights aboard the NASA DC-8 as well as in-situ research on atmospheric chemistry (bovine emissions of methane); algal blooms (remote sensing to determine location and degree of blooms for further in-situ analysis); and crop classification (exploration of how drought conditions in Central California have impacted almond and cotton crops). AREE represents a unique model of the STEM teacher-as-researcher professional development experience because it asks educators to participate in a research experience and then translate their experiences into classroom practice through the design, implementation, and evaluation of instructional materials that emphasize the scientific research process, inquiry-based investigations, and manipulation of real data. Each AREE Master Educator drafted a Curriculum Brief, Teachers Guide, and accompanying resources for a topic in their teaching assignment Currently, most professional development programs offer either a research experience OR a curriculum development experience. The dual nature of the AREE model engaged educators in both experiences. Educators’ content and pedagogical knowledge of STEM was increased through the review of pertinent research articles during the first week, attendance at lectures and workshops during the second week, and participation in the airborne and in-situ research studies, data

    2015-04-01

    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. 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

    2009-12-01

    The Arctic Mars Analogue Svalbard Expedition (AMASE) continued its multi-year campaign in August 2009 to study selected sedimentary and igneous environments in this geological diverse archipelago using a variety of measurement techniques and protocols that are candidates for future Mars missions. The X-ray diffraction mineralogical and evolved gas analysis (EGA) employed during the AMASE-2009 campaign closely mimicked similar experiments that are planned for the 2011 Mars Science Laboratory (MSL). Field instruments similar to those under development for the ESA ExoMars or other rover missions provided imaging, spectroscopic, and subsurface sounding data. A variety of microbiology and field life detection techniques rounded out the AMASE-2009 analytical tools. The evolved gas mass spectrometer utilized on AMASE-2009 was designed to model elements of the Sample Analysis at Mars (SAM) suite of instruments on MSL. Powdered rock samples were heated from ambient to 1000 C in a helium stream and evolved gases continuously analyzed by a mass spectrometer. A continued focus of AMASE-2009 was analysis of carbonates from the Spitsbergen Sverrefjell volcano [1]. The similarity of macromolecular carbon (MMC) associated with magnetite in carbonate globules found in an ice cave in Sverrefjell to those studied in the Mars meteorite ALH84001 has been a motivation for their intensive study. The MMC associated with these carbonates appears to have been formed abiotically [2] following the eruption of the Sverrefjell volcano into glacial ice. The AMASE-2008 EGA studies of microsampled carbonate layers are described and the ability and limitations of these in situ tools to distinguish biomarkers. [1] H.

    2012-09-17

    The volume of methane released through the Arctic Ocean to the atmosphere and its potential role in the global climate cycle have increasingly become the focus of studies seeking to understand the source and origin of this methane. In 2009, an international, multi-disciplinary science party aboard the U.S. Coast Guard icebreaker Polar Sea successfully completed a trans-U.S. Beaufort Shelf expedition aimed at understanding the sources and volumes of methane across this region. Following more than a year of preliminary cruise planning and a thorough site evaluation, the Methane in the Arctic Shelf/Slope (MITAS) expedition departed from the waters off the coast of Barrow, Alaska in September 2009. The expedition was organized with an international shipboard science team consisting of 33 scientists with the breadth of expertise necessary to meet the expedition goals. NETL researchers led the expedition’s initial core processing and lithostratigraphic evaluations, which are the focus of this report. This data report is focused on the lithostratigraphic datasets from the recovered vibra cores and piston cores. Operational information about the piston and vibra cores such as date acquired, core name, total length, water depth, and geographic location is provided. Once recovered, gas samples were immediately collected from cores. In addition, each core was run through the Geotek multi-sensor core logger for magnetic susceptibility, P-wave velocity, resistivity, and gamma-density measurements (Rose et al., 2010). After the samples and measurements were completed, the cores were split into working and archive halves. Visual core descriptions of the archive half was completed for each core. Samples for shipboard smear slides, coarse fractions, and XRD analyses were collected, as well as corresponding samples for post-cruise grain size analysis from the working half of each core. Line scan images of the split core surfaces were collected post-expedition. The methods used to

    Much is known about psychological and interpersonal issues affecting astronauts participating in manned space missions near the Earth. But in a future long-distance, long-duration expedition to Mars, additional stressors will occur that will result in psychological, psychiatric, and interpersonal effects on the crew, both negative and positive. This paper will review what is known about important psychosocial issues in space and will extrapolate them to the scenario of a future manned space mission to Mars.

  11. Solar Eclipse Expeditions of Hamburg Observatory

    NASA Astrophysics Data System (ADS)

    Wolfschmidt, Gudrun

    2012-09-01

    Total solar eclipses had -- and still have, in spite of the maximum duration of eight minutes -- an important meaning for astronomical research. For a long time in the 19th century astronomers were searching for a planet inside the orbit of Mercury. But especially, the solar atmosphere was studied: during an eclipse the bright photosphere is covered by the moon and enables the observation of the chromosphere with the prominences and the flash spectrum. George Rümker (1832--1900), the third director of Hamburg Observatory, made a solar eclipse expedition to Spain in 1860. He used only small instruments like a 4-foot Fraunhofer telescope and a comet seeker. Richard Schorr (1867--1951), the director of the new Hamburg Observatory in Bergedorf, observed in 1905 the solar eclipse in Algeria and put the emphasis on astrophysical research, investigation of the inner corona and the prominences. A horizontal telescope with 20-m focal length and an equatorial double refractor were acquired, both instruments made by Carl Zeiss of Jena. This instrumentation and many smaller instruments were used for all the expeditions in the 1920s, like in 1922 -- Java, in 1923 -- Mexico, in 1925 -- Atlantic Ocean, in 1927 -- Jokkmokk, Sweden, and in 1929 -- Philippines. These Hamburg solar expeditions of the 1920s put the emphasis on two topics: to solve the so-called riddle of coronium, or mystery of coronium -- the nature of the green emission line -- and to measure the deviation of light for verifying Einstein's general theory of relativity.

  12. Martian Polar Expeditions: Problems and Solutions

    NASA Astrophysics Data System (ADS)

    Cockell, Charles S.

    2001-12-01

    The Martian polar ice caps are regions of substantial scientific interest, being the most dynamic regions of Mars. They are volatile sinks and thus closely linked to Martian climatic conditions. Because of their scale and the precedent set by the past history of polar exploration on Earth, it is likely that an age of polar exploration will emerge on the surface of Mars after the establishment of a capable support structure at lower latitudes. Expeditions might be launched either from a lower latitude base camp or from a human-tended polar base. Based on previously presented expeditionary routes to the Martian poles, in this paper a "spiral in-spiral out" unsupported transpolar assault on the Martian north geographical pole is used as a Reference expedition to propose new types of equipment for the human polar exploration of Mars. Martian polar "ball" tents and "hover" modifications to the Nansen sledge for sledging on CO 2-containing water ice substrates under low atmospheric pressures are suggested as elements for the success of these endeavours. Other challenges faced by these expeditions are quantitatively and qualitatively addressed.

    A joint Indonesia - U.S. Expedition to Sangihe Talaud waters (INDEX SATAL) in the north area of the North Sulawesi Province has been conducted by the Okeanos Explorer of NOAA and the Baruna Jaya IV of Indonesia during July - August, 2010. The joint expedition was the first of its kind that covered multi aspects of science which aimed at discoveries of deep sea potential resources and processes in the sea of Sangihe Talaud. Considering the advantage of both ship capabilities, the Okeanos Explorer covered the area of larger depths of 2000 metres to 6000 metres, while the Baruna Jaya IV worked the area of less than 2000 metres. Using multibeam equipment, the Okeanos Explorer discovered deep sea features of seamounts and bathymetric pattern of the western Sangihe ridge, Talaud ridge and the northeastern part of the exploration area. Deep sea morphology and bathymetric features of the area show newly discovery of seamounts and other deep sea features. The largest seamount in the explored area, the Kawio Barat seamount, has been discovered as an active submarine volcano showing hydrothermal activities. CTD casts in selected locations indicated the occurence of hydrothermal activities, which were later confirmed by ROV (Remotely Operated Vehicles) equipped with high definition cameras. Chimneys and smokers in the Kawio Barat and their associated deep sea biotas were recorded. Variety of seabed rocks in the dive areas were also recorded. Baruna Jaya IV explored the Sangihe ridge with multibeam and supported by CTD casts and sampling devices. Bathymetric features of less than 2000 metres were recorded and various deep sea biotas were discovered and sampled. Discoveries by INDEX SATAL 2010 has provided an insight into deep sea resources, specific features, volcanic and hydrothermal processes and potentials for further identifications.

    The project called High-Speed On-Board Data Processing for Science Instruments (HOPS) has been funded by NASA Earth Science Technology Office (ESTO) Advanced Information Systems Technology (AIST) program since April, 2012. The HOPS team recently completed two flight campaigns during the summer of 2014 on two different aircrafts with two different science instruments. The first flight campaign was in July, 2014 based at NASA Langley Research Center (LaRC) in Hampton, VA on the NASA's HU-25 aircraft. The science instrument that flew with HOPS was Active Sensing of CO2 Emissions over Nights, Days, and Seasons (ASCENDS) CarbonHawk Experiment Simulator (ACES) funded by NASA's Instrument Incubator Program (IIP). The second campaign was in August, 2014 based at NASA Armstrong Flight Research Center (AFRC) in Palmdale, CA on the NASA's DC-8 aircraft. HOPS flew with the Multifunctional Fiber Laser Lidar (MFLL) instrument developed by Excelis Inc. The goal of the campaigns was to perform an end-to-end demonstration of the capabilities of the HOPS prototype system (HOPS COTS) while running the most computationally intensive part of the ASCENDS algorithm real-time on-board. The comparison of the two flight campaigns and the results of the functionality tests of the HOPS COTS are presented in this paper.

    The South China Sea (SCS) is one of the largest low-latitude marginal seas in the world, serving as a natural laboratory for studying the linkages between complex tectonic, volcanic, and oceanic processes. The last several years have witnessed significant progress in investigation of the SCS through comprehensive research programs using multidisciplinary approaches and enhanced international collaboration. In January-March 2014, International Ocean Discovery Program (IODP) Expedition 349 drilled and cored five sites in the SCS, with three sites located near the relict spreading center in the East and Southwest Subbasins and two sites near the transition zone between the oceanic and continental crust (Expedition 349 Scientists, 2014). The expedition successfully obtained the first basaltic rock samples of the SCS relict spreading center, discovered large and frequent deep-sea turbidity events, and sampled multiple seamount volcaniclastic layers. The Expedition 349 shipboard and shorebased research involves the participation and strong collaboration of scientists from the international community including scientists from countries and regions surrounding the SCS. Meanwhile, major progress in studying the SCS processes has also been made through comprehensive multidisciplinary programs, for example, the "South China Sea Deep" initiative (Wang, 2012). This presentation will highlight the recent multidisciplinary research initiatives in investigation of the SCS and the important role of international collaboration. Expedition 349 Scientists, 2014.

    2014-12-01

    IODP Expedition #352 (Testing Subduction Initiation and Ophiolite Models by Drilling the Outer Izu-Bonin-Mariana Forearc: July 30-Sept. 29, 2014) is just underway at the time of writing. It is testing the Stern-Bloomer hypothesis that subduction initiation (SI) was followed by a strongly extensional period of slab sinking and trench roll-back and then by a transitional period leading to the establishment of significant slab-parallel plate motion and hence normal subduction. The Expedition aims to carry out offset drilling at two sites near 28°30'N in the Bonin forearc. Ideally, these together will give the vertical volcanic stratigraphy needed to trace the geodynamic and petrogenetic processes associated with SI, and provide the complete reference section required for comparison with volcanic sequences of possible SI origin found on land in ophiolite complexes and elsewhere. We predict, but need to confirm, a c. 1.0-1.5km sequence with basal, MORB-like forearc basalts (known as FAB) marking the initial period of extension, boninites characterizing the transitional period, and tholeiitic and calc-alkaline lavas marking the establishment of normal arc volcanism. Study of such a sequence will enable us to understand the chemical gradients within and across these volcanic units, to reconstruct mantle flow and melting processes during the course of SI, and to test the hypothesis that fore-arc lithosphere created during SI is the birthplace of most supra-subduction zone ophiolites. Here, we present the first Expedition results, including (a) the volcanic stratigraphic record and subdivision into lava units, (b) the classifications and interpretations made possible by shipboard (portable XRF and ICP) analyses and down-hole measurements, and (c) the biostratigraphic, magnetic, mineralogical, sedimentary and structural constraints on the geological history of the SI section and the interactions between magmatic, hydrothermal and tectonic activity during its evolution.

    With Congress appropriating approximately $1.0--1.5 Billion each year for Department of Defense (DOD) Environmental Restoration Program (DERP), every effort must be made to find ways to use these funds efficiently and effectively to nations hazardous waste sites. Each federal agency involved in environmental restoration is striving to find smarter, faster ways to accomplish this service. The Omaha District Corps of Engineers, Hazardous and Toxic Waste Branch (Omaha) and the Air Combat Command Installation Restoration Branch (ACC) have teamed up to develop and implement an innovative Accelerated Clean-up Program which with the President`s edict for expedited installation environmental restoration.

  7. 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.

    In March 2007, a group of international students of the geosciences will embark on a two month expedition across the wilderness of Svalbard. The journey will involve traversing up to 1000 km of high Arctic glaciers between 76° an 80°N, reaching both the southernmost and northernmost capes of Spitsbergen, Svalbard's largest island. We expect to be frequently camping at -30°C, as well as having a high probability of encountering polar bears, crevasses and arctic storms during the expedition. Through this expedition, we wish to promote the multi-disciplinary approach required in successful Arctic science. Our team, young and energetic, has already demonstrated a strong research interest in the Arctic and is ready to share their passion with the general public. Presentations by the various team members focus on the enhanced climate change and related processes witnessed at high latitudes. The concept of alternative energy, including solar power and kites used while en route, is given a high priority throughout. Here we present the education and outreach framework of the project, as well as introducing the research background of the team. We highlight current progress on the integration of this expedition in high schools around the world. The Frozen Five expedition runs in close collaboration with New Zealand's Youth Steering Committee, a major IPY project, aiming to network young polar researchers and promote the study of the polar regions to potential scientists.

  9. Airborne data acquisition techniques

    SciTech Connect

    Arro, A.A.

    1980-01-01

    The introduction of standards on acceptable procedures for assessing building heat loss has created a dilemma for the contractor performing airborne thermographic surveys. These standards impose specifications on instrumentation, data acquisition, recording, interpretation, and presentation. Under the standard, the contractor has both the obligation of compliance and the requirement of offering his services at a reasonable price. This paper discusses the various aspects of data acquisition for airborne thermographic surveys and various techniques to reduce the costs of this operation. These techniques include the calculation of flight parameters for economical data acquisition, the selection and use of maps for mission planning, and the use of meteorological forecasts for flight scheduling and the actual execution of the mission. The proper consideration of these factors will result in a cost effective data acquisition and will place the contractor in a very competitive position in offering airborne thermographic survey services.

    This article examines the International High Altitude Expedition of 1935 and its significance in the life and science of Ancel Keys. Both the expedition and Keys's story afford excellent opportunities to explore the growing reach of interwar physiology into extreme climates-whether built or natural. As IHAE scientists assessed human performance and adaptation to hypoxia, low barometric pressure, and cold, they not only illuminated the physiological and psychological processes of high altitude acclimatization, but they also drew borderlines between the normal and the pathological, paved the way for the neocolonial exploitation of natural and human resources in Latin America, and pioneered field methods in physiology that were adapted and adopted by the Allied Forces during the Second World War. This case study in the physiology of place reveals the power and persistence of environmental determinism within biomedicine well into the twentieth century. PMID:23263349

  12. NASA/Ames Research Center's science and applications aircraft program

    1991-01-01

    NASA-Ames Research Center operates a fleet of seven Science and Applications Aircraft, namely the C-141/Kuiper Airborne Observatory (KAO), DC-8, C-130, Lear Jet, and three ER-2s. These aircraft are used to satisfy two major objectives, each of equal importance. The first is to acquire remote and in-situ scientific data in astronomy, astrophysics, earth sciences, ocean processes, atmospheric physics, meteorology, materials processing and life sciences. The second major objective is to expedite the development of sensors and their attendant algorithms for ultimate use in space and to simulate from an aircraft, the data to be acquired from spaceborne sensors. NASA-Ames Science and Applications Aircraft are recognized as national and international facilities. They have performed and will continue to perform, operational missions from bases in the United States and worldwide. Historically, twice as many investigators have requested flight time than could be accommodated. This situation remains true today and is expected to increase in the years ahead. A major advantage of the existing fleet of aircraft is their ability to cover a large expanse of the earth's ecosystem from the surface to the lower stratosphere over large distances and time aloft. Their large payload capability allows a number of scientists to use multi-investigator sensor suites to permit simultaneous and complementary data gathering. In-flight changes to the sensors or data systems have greatly reduced the time required to optimize the development of new instruments. It is doubtful that spaceborne systems will ever totally replace the need for airborne science aircraft. The operations philosophy and capabilities exist at NASA-Ames Research Center.

  5. NASA's Airborne Astronomy Program - Lessons For SOFIA

    Erickson, Edwin F.

    2007-07-01

    Airborne astronomy was pioneered and has evolved at NASA Ames Research Center near San Francisco, California, since 1965. Nowhere else in the world has a similar program been implemented. Its many unique features deserve description, especially for the benefit of planning the operation of SOFIA, the Stratospheric Observatory for Infrared Astronomy, and in particular since NASA Headquarters’ recent decision to base SOFIA operations at Dryden Flight Research Center at Edwards, California instead of at Ames. The history of Ames’ airborne astronomy program is briefly summarized. Discussed in more detail are the operations and organization of the 21-year Kuiper Airborne Observatory (KAO) program, which provide important lessons for SOFIA. The KAO program is our best prototype for planning effective SOFIA operations. Principal features of the KAO program which should be retained on SOFIA are: unique science, innovative new science instruments and technologies, training of young scientists, an effective education and public outreach program, flexibility, continuous improvement, and efficient operations with a lean, well integrated team. KAO program features which should be improved upon with SOFIA are: (1) a management structure that is dedicated primarily to safely maximizing scientific productivity for the resources available, headed by a scientist who is the observatory director, and (2) stimuli to assure prompt distribution and accessibility of data to the scientific community. These and other recommendations were recorded by the SOFIA Science Working Group in 1995, when the KAO was decommissioned to start work on SOFIA. Further operational and organizational factors contributing to the success of the KAO program are described. Their incorporation into SOFIA operations will help assure the success of this new airborne observatory. SOFIA is supported by NASA in the U.S. and DLR (the German Aerospace Center) in Germany.

  7. Field Innovations in Support of Martian Polar Expeditions

    NASA Astrophysics Data System (ADS)

    Cockell, C. S.

    The Martian poles present a challenging environment for expedition planners. I review and describe innova- tions in support of human Martian polar expeditions that are a direct extrapolation of terrestrial polar explora- tion equipment. Ball tents provide an environment for de-suiting at the end of daily expedition traverse and can be used to establish temporary field camps and depots for transpolar expeditions or deep-field scientific outposts. Sublimation poles, netting and heating boxes allow for the harvesting of polar ices for water, oxygen and fuel production. Pressurization of ices prior to melting allows liquid water to be collected, thus reducing energy expenditure compared to ice vaporization. Sublimation nets additionally are used for the removal of CO2 frost from expedition equipment. Human mobility can be achieved with sledges and rovers. These innova- tions, when combined, make possible the planning of human scientific and expeditionary EVAs on the Martian polar ice caps.

  8. High spatial resolution imaging of methane and other trace gases with the airborne Hyperspectral Thermal Emission Spectrometer (HyTES)

    Currently large uncertainties exist associated with the attribution and quantification of fugitive emissions of criteria pollutants and greenhouse gases such as methane across large regions and key economic sectors. In this study, data from the airborne Hyperspectral Thermal Emission Spectrometer (HyTES) have been used to develop robust and reliable techniques for the detection and wide-area mapping of emission plumes of methane and other atmospheric trace gas species over challenging and diverse environmental conditions with high spatial resolution that permits direct attribution to sources. HyTES is a pushbroom imaging spectrometer with high spectral resolution (256 bands from 7.5 to 12 µm), wide swath (1-2 km), and high spatial resolution (˜ 2 m at 1 km altitude) that incorporates new thermal infrared (TIR) remote sensing technologies. In this study we introduce a hybrid clutter matched filter (CMF) and plume dilation algorithm applied to HyTES observations to efficiently detect and characterize the spatial structures of individual plumes of CH4, H2S, NH3, NO2, and SO2 emitters. The sensitivity and field of regard of HyTES allows rapid and frequent airborne surveys of large areas including facilities not readily accessible from the surface. The HyTES CMF algorithm produces plume intensity images of methane and other gases from strong emission sources. The combination of high spatial resolution and multi-species imaging capability provides source attribution in complex environments. The CMF-based detection of strong emission sources over large areas is a fast and powerful tool needed to focus on more computationally intensive retrieval algorithms to quantify emissions with error estimates, and is useful for expediting mitigation efforts and addressing critical science questions.

    The concentration of airborne asbestos in buildings nationwide is reported in this study. A total of 3978 indoor samples from 752 buildings, representing nearly 32 man-years of sampling, have been analyzed by transmission electron microscopy. The buildings that were surveyed were the subject of litigation related to suits alleging the general building occupants were exposed to a potential health hazard as a result the presence of asbestos-containing materials (ACM). The average concentration of all airborne asbestos structures was 0.01structures/ml (s/ml) and the average concentration of airborne asbestos > or = 5microm long was 0.00012fibers/ml (f/ml). For all samples, 99.9% of the samples were <0.01 f/ml for fibers longer than 5microm; no building averaged above 0.004f/ml for fibers longer than 5microm. No asbestos was detected in 27% of the buildings and in 90% of the buildings no asbestos was detected that would have been seen optically (> or = 5microm long and > or = 0.25microm wide). Background outdoor concentrations have been reported at 0.0003f/ml > or = 5microm. These results indicate that in-place ACM does not result in elevated airborne asbestos in building atmospheres approaching regulatory levels and that it does not result in a significantly increased risk to building occupants.

    Airborne geophysics can be defined as the measurement of Earth properties from sensors in the sky. The airborne measurement platform is usually a traditional fixed-wing airplane or helicopter, but could also include lighter-than-air craft, unmanned drones, or other specialty craft. The earliest history of airborne geophysics includes kite and hot-air balloon experiments. However, modern airborne geophysics dates from the mid-1940s when military submarine-hunting magnetometers were first used to map variations in the Earth's magnetic field. The current gamut of airborne geophysical techniques spans a broad range, including potential fields (both gravity and magnetics), electromagnetics (EM), radiometrics, spectral imaging, and thermal imaging.

    In the late nineteenth and early twentieth centuries, a number of European expeditions traveled to the region of Lake Rudolf, now largely in northern Kenya. Although diverse in intent, many of these were undertaken in the interests of furthering colonial territorial claims. In 1900-1901, Major Herbert Henry Austin led a British expedition down to the lake from Khartoum in the north. Of the 62 African, Arab, and European members of this expedition, only 18 (29 %) arrived at its final destination at Lake Baringo in Kenya. Because of a confluence of adverse climatic, social, and political conditions, the expedition ran short of food supplies when it arrived at the northern end of the lake in April 1901. For the next 4 months, the members of the expedition struggled down the west side of the lake and beyond. The greatest mortality (91 %) occurred among the 32 African transport drivers who were the most marginally nourished at the outset of the trip. The lowest mortality among the Africans on the expedition (15 %) occurred among the members of the Tenth Sudanese Rifles Battalion, who had an excellent nutritional status at the start of the expedition. Major Austin himself suffered from severe scurvy with retinal hemorrhages which left him partially blind in his right eye. An analysis of the mortality rates among the groups that participated in this expedition was undertaken. This revealed that poor nutritional status at the start of the trip was predictive of death from starvation.

  14. Virtual Research Expeditions along Plate Margins: Examples from an Online Oceanography Course

    An undergraduate online course in oceanography is based on the participation of each student in a series of virtual, at-sea, research expeditions, two of which are used to examine the tectonic processes at plate boundaries. The objective is to leverage the results of major federal research initiatives in the ocean sciences into effective learning tools with a long lifespan for use in undergraduate geoscience courses. These web-based expeditions examine: (1) hydrothermal vents along the divergent plate boundary at the Explorer Ridge and (2) the convergent plate boundary fault along the Nankai Trough, which is the objective of the multi-year NanTroSEIZE drilling program. Here we focus on the convergent plate boundary in NanTroSEIZE 3-D, which is based on a seismic survey supported through NSF-MARGINS, IODP and CDEX in Japan to study the properties of the plate boundary fault system in the upper limit of the seismogenic zone off Japan. The virtual voyage can be used in undergraduate classes at anytime, since it is not directly tied to the finite duration of a specific seagoing project, and comes in two versions, one that is being used in geoscience major courses and the other in non-major courses, such as the oceanography course mentioned above and a lower-division global studies course with a science emphasis. NanTroSEIZE in 3-D places undergraduate learning in an experiential framework as students participate on the expedition and carry out research on the structure of the plate boundary fault. Students learn the scientific background of the program, especially the critical role of international collaboration, and meet the chief scientists before joining the 3-D seismic imaging expedition to identify the active faults that were the likely sources of devastating earthquakes and tsunamis in Japan in 1944 and 1948. The initial results of phase I ODP drilling that began in 2007 are also reviewed. Students document their research on a worksheet that accompanies the

  15. Photoreactivation in Airborne Mycobacterium parafortuitum

    PubMed Central

    Peccia, Jordan; Hernandez, Mark

    2001-01-01

    Photoreactivation was observed in airborne Mycobacterium parafortuitum exposed concurrently to UV radiation (254 nm) and visible light. Photoreactivation rates of airborne cells increased with increasing relative humidity (RH) and decreased with increasing UV dose. Under a constant UV dose with visible light absent, the UV inactivation rate of airborne M. parafortuitum cells decreased by a factor of 4 as RH increased from 40 to 95%; however, under identical conditions with visible light present, the UV inactivation rate of airborne cells decreased only by a factor of 2. When irradiated in the absence of visible light, cellular cyclobutane thymine dimer content of UV-irradiated airborne M. parafortuitum and Serratia marcescens increased in response to RH increases. Results suggest that, unlike in waterborne bacteria, cyclobutane thymine dimers are not the most significant form of UV-induced DNA damage incurred by airborne bacteria and that the distribution of DNA photoproducts incorporated into UV-irradiated airborne cells is a function of RH.

    In eighteenth-century France, geodesy (the measure of the earth's shape) became an arena where mathematics and narrative intersected productively. Mathematics played a crucial role not only in the measurements and analysis necessary to geodesy but also in the narrative accounts that presented the results of elaborate and expensive expeditions to the reading public. When they returned to France to write these accounts after their travels, mathematician-observers developed a variety of ways to display numbers and mathematical arguments and techniques. The numbers, equations, and diagrams they produced could not be separated from the story of their acquisition. Reading these accounts for the interplay of these two aspects--the mathematical and the narrative--shows how travelers articulated the intellectual and physical difficulties of their work to enhance the value of their results for specialist and lay readers alike.

    In July 14-30, 1999 an Italian scientific expedition was carried out in Tunguska (Siberia), the region of the 1908 explosion of a cosmic body. The main tasks of the expedition were: 1) to study the structure and sediments of Cheko, a small lake located near the epicenter of the Tunguska event; 2) to carry out an aerial photosurvey of the explosion site; 3) to collect wood, peat and rock samples; 4) to monitor gamma rays during the flight Italy - Siberia - Italy and in Tunguska. 1) Our bathymetric mapping of lake Cheko and ultrasound and radar subbottom surveys of stratigraphy suggest that the lake is older than the Tunguska event. 28 cores up to 2 m long have been extracted from the lake bottom (at depths up to 50 m). They show a clear stratigraphy and the analyses at the CNR Institute of Marine Geology in Bologna will hopefully throw light on the nature of the exploded body. 2) The aerial multispectral photosurvey (performed from visual to thermal infrared wave lenghts) together with our GPS coordinate measurements on the ground of some reference points, will be used to re-examine some details of the explosion. 3) The petrology and geochemistry of the Mesozoic igneous rocks outcropping in the Tunguska region is being studied and the collected wood, peat and rock samples will be analyzed in different laboratories to find traces of the cosmic body. 4) The data on gamma rays are being processed in the Bologna University to find their dependence on altitude, longitude, latitude and atmospheric conditions.

    The Integrated Ocean Drilling Program (IODP), an international collaboration of Earth, ocean, and life scientists that began in 2003, offers scientists worldwide unprecedented opportunities to address a vast array of scientific problems in all submarine settings. Recently, the scientific advisory structure of the proposal-driven IODP scheduled drilling expeditions, targeting critical scientific problems in the Atlantic Ocean, Gulf of Mexico, and Pacific Ocean, for 2005 and early 2006 (Figure 1, Table 1). The IODP, which is co-led by Japan and the United States, with strong contributions from the European Consortium for Ocean Research Drilling (ECORD) and China, is guided by an initial science plan, ``Earth, Oceans, and Life'' (www.iodp.org). For the first time, through the IODP, scientists have at their disposal both a riser (drilling vessel which has a metal tube surrounding the drill pipe that enables the return of drilling fluid and cuttings to the drill ship; the ``riser'' is attached to a ``blow-out preventer'' or shut-off device at the seafloor) and riserless drilling vessel (which lacks a riser pipe and blow-out preventer), as well as mission-specific capabilities such as drilling barges and jack-up rigs for shallow-water and Arctic drilling.

    2012-09-01

    During the years 1898 to 1932, Lick Observatory organized a remarkable series of 17 solar eclipse expeditions, all the more remarkable because Lick astronomers evidenced no enduring interest in solar physics. The science of these expeditions involved three issues of major significance during the development of astrophysics during the first three decades of the twentieth century: (1) testing of General Relativity; (2) non-LTE in extended atmospheres and gaseous nebulae; (3) role of magnetic fields in the sun. The expeditions made major contributions to the first two topics. Even though W.W. Campbell, the director of Lick, had extensive contact with George Ellery Hale, who had measured the magnetic fields of sunspots at Mt. Wilson, Lick astronomers missed the clues concerning the importance of magnetic fields in the corona. Campbell's measurement of the deflection of starlight at the eclipse of 1922 was his major achievement of the many eclipse expeditions. He had approached that test of General Relativity with considerable distrust of Einstein's theory and considered Eddington's 1919 results to be suspect. It is to Campbell's great credit that the results published jointly with Trumpler confirmed the predictions of Einstein with higher precision than Eddington had achieved. Donald Menzel joined the staff of Lick Observatory in 1926 as their first astrophysicist. Osterbrock describes him as a ``stranger in a strange land.'' He was given the analysis of the eclipse flash spectra. This work, published in 1931, represents the beginning of the astrophysical study of chromospheres and laid the foundation for the quantitative analysis of extended atmospheres and gaseous nebula.

    Respiratory protection is a factor which worries nursing professionals who take care of patients susceptible of transmitting microorganisms through the air more as every day passes. This type of protection covers the use of surgical or hygienic masks against the transmission of infection by airborne drops to the use of highly effective masks or respirators against the transmission of airborne diseases such as tuberculosis or SARS, a recently discovered disease.

    The geometrical theory of diffraction was used to analyze the elevation plane pattern of on-aircraft antennas. The radiation patterns for basic elements (infinitesimal dipole, circumferential and axial slot) mounted on fuselage of various aircrafts with or without radome included were calculated and compared well with experimental results. Error phase plots were also presented. The effects of radiation patterns and error phase plots on the polarization selection for the MLS airborne antenna are discussed.

  11. Mutagenicity of airborne particles.

    1980-09-01

    The physical and chemical properties of airborne particles are important for the interpretation of their potential biologic significance as genotoxic hazards. For polydisperse particle size distributions, the smallest, most respirable particles are generally the most mutagenic. Particulate collection for testing purposes should be designed to reduce artifact formation and allow condensation of mutagenic compounds. Other critical factors such as UV irradiation, wind direction, chemical reactivity, humidity, sample storage, and temperature of combustion are important. Application of chemical extraction methods and subsequent class fractionation techniques influence the observed mutagenic activity. Particles from urban air, coal fly ash, automobile and diesel exhaust, agricultural burning and welding fumes contain primarily direct-acting mutagens. Cigarette smoke condensate, smoke from charred meat and protein pyrolysates, kerosene soot and cigarette smoke condensates contain primarily mutagens which require metabolic activation. Fractionation coupled with mutagenicity testing indicates that the most potent mutagens are found in the acidic fractions of urban air, coal fly ash, and automobile diesel exhaust, whereas mutagens in rice straw smoke and cigarette smoke condensate are found primarily in the basic fractions. The interaction of the many chemical compounds in complex mixtures from airborne particles is likely to be important in determining mutagenic or comutagenic potentials. Because the mode of exposure is generally frequent and prolonged, the presence of tumor-promoting agents in complex mixtures may be a major factor in evaluation of the carcinogenic potential of airborne particles.

  12. Mammalian airborne allergens.

    Historically, horse dandruff was a favorite allergen source material. Today, however, allergic symptoms due to airborne mammalian allergens are mostly a result of indoor exposure, be it at home, at work or even at school. The relevance of mammalian allergens in relation to the allergenic activity of house dust extract is briefly discussed in the historical context of two other proposed sources of house dust allergenic activity: mites and Maillard-type lysine-sugar conjugates. Mammalian proteins involved in allergic reactions to airborne dust are largely found in only 2 protein families: lipocalins and secretoglobins (Fel d 1-like proteins), with a relatively minor contribution of serum albumins, cystatins and latherins. Both the lipocalin and the secretoglobin family are very complex. In some instances this results in a blurred separation between important and less important allergenic family members. The past 50 years have provided us with much detailed information on the genomic organization and protein structure of many of these allergens. However, the complex family relations, combined with the wide range of post-translational enzymatic and non-enzymatic modifications, make a proper qualitative and quantitative description of the important mammalian indoor airborne allergens still a significant proteomic challenge.

    1998-01-01

    This is the final technical report for NASA-Ames grant NAG2-1068 to Caltech, entitled "Airborne Submillimeter Spectroscopy", which extended over the period May 1, 1996 through January 31, 1998. The grant was funded by the NASA airborne astronomy program, during a period of time after the Kuiper Airborne Observatory was no longer operational. Instead. this funding program was intended to help develop instrument concepts and technology for the upcoming SOFIA (Stratospheric Observatory for Infrared Astronomy) project. SOFIA, which is funded by NASA and is now being carried out by a consortium lead by USRA (Universities Space Research Association), will be a 747 aircraft carrying a 2.5 meter diameter telescope. The purpose of our grant was to fund the ongoing development of sensitive heterodyne receivers for the submillimeter band (500-1200 GHz), using sensitive superconducting (SIS) detectors. In 1997 July we submitted a proposal to USRA to construct a heterodyne instrument for SOFIA. Our proposal was successful [1], and we are now continuing our airborne astronomy effort with funding from USRA. A secondary purpose of the NAG2-1068 grant was to continue the anaIN'sis of astronomical data collected with an earlier instrument which was flown on the NASA Kuiper Airborne Observatory (KAO). The KAO instrument and the astronomical studies which were carried out with it were supported primarily under another grant, NAG2-744, which extended over October 1, 1991 through Januarv 31, 1997. For a complete description of the astronomical data and its anailysis, we refer the reader to the final technical report for NAG2-744, which was submitted to NASA on December 1. 1997. Here we report on the SIS detector development effort for SOFIA carried out under NAG2-1068. The main result of this effort has been the demonstration of SIS mixers using a new superconducting material niobium titanium nitride (NbTiN), which promises to deliver dramatic improvements in sensitivity in the 700

    The NOAA Center for Atmospheric Sciences (NCAS) is sponsoring a Trans-Atlantic Saharan Dust AERosol and Ocean Science Expedition (AEROSE) aboard the NOAA Ship Ronald H. Brown in March 2004. The fundamental purpose of this aerosol cruise is to study the impacts and microphysical evolution of Saharan dust aerosol as it is transported across the Atlantic Ocean. The mission encompasses both, atmospheric and oceanographic components. Participating institutions include Howard University, NCAS lead institution, the University of Puerto Rico at Mayagüez, the Canary Institute of Marine Sciences, the Spanish Institute of Oceanography, the Laboratory of Atmospheric Physics Siméon Fongang, the University of Miami Rosenstiel School of Marine and Atmospheric Science, the University of Washington Applied Physics Laboratory, NASA Goddard Space Flight Center, the NOAA Cooperative Institute for Meteorological Satellite Studies at the University of Wisconsin-Madison, NASA Jet Propulsion Laboratory, and the NOAA/NESDIS Office of Research and Applications. This collaboration provides unique atmospheric and oceanic observations across the North Tropical Atlantic during eastward and westward tracks during a period of nearly one month. Characterization of microphysical properties of Saharan dust aerosol is done trough direct observations of mass, size, and particle number distributions, chemical composition, spatial distributions, and air chemistry. Aerosol radiative properties are studied through a suite of sensors that include a Multi-Angle Absorption Photometer (MAAP), the Marine-Atmosphere Emitted Radiance Interferometer (M-AERI), sunphotometers, and an assortment of other radiometers. Characterization of atmospheric conditions is done through a combination of over 250 radiosonde and ozonesonde launches at 3 to 5 hour intervals during the duration of the cruise and in coordination with satellite overpasses. AEROSE is also supporting the collection of bio-optics and oceanographic

    1994-01-01

    Since signing the Hanford Federal Facility Agreement and Consent Order (Tri-Party Agreement) in 1989, the parties to the agreement have recognized the need to modify the approach to conducting investigations, studies, and cleanup actions at Hanford. To implement this approach, the parties have jointly developed the Hanford Past-Practice Strategy. The strategy defines a non-time-critical expedited response action (ERA) as a response action ``needed to abate a threat to human health or welfare or the environment where sufficient time exists for formal planning prior to initiation of response. In accordance with the past-practice strategy, DOE proposes to conduct an ERA at the N Springs, located in the Hanford 100 N Area, to substantially reduce the strontium-90 transport into the river through the groundwater pathway. The purpose of this ERA proposal is to provide sufficient information to select a preferred alternative at N Springs. The nature of an ERA requires that alternatives developed for the ERA be field ready; therefore, all the technologies proposed for the ERA should be capable of addressing the circumstances at N Springs. A comparison of these alternatives is made based on protectiveness, cost, technical feasibility, and institutional considerations to arrive at a preferred alternative. Following the selection of an alternative, a design phase will be conducted; the design phase will include a detailed look at design parameters, performance specifications, and costs of the selected alternative. Testing will be conducted as required to generate design data.

    1998-12-01

    Expedited Site Characterization (ESC) has been developed, demonstrated, and deployed as a new time-saving, cost-effective approach for hazardous waste site investigations. ESC is an alternative approach that effectively shortens the length of the assessment period and may significantly reduce costs at many sites. It is not a specific technology or system but is a methodology for most effectively conducting a site characterization. The principal elements of ESC are: a field investigation conducted by an integrated team of experienced professionals working in the field at the same time, analysis, integration and initial validation of the characterization data as they are obtained in the field, and a dynamic work plan that enables the team to take advantage of new insights from recent data to adjust the work plan in the field. This report covers demonstrations that took place between 1989 and 1996. This paper gives a description of the technology and discusses its performance, applications, cost, regulatory and policy issues, and lessons learned.

    1993-09-01

    The US Environmental Protection Agency (EPA) and Washington Department of Ecology (Ecology) recommended that the US Department of Energy (DOE) perform an expedited response action (ERA) for the Sodium Dichromate Barrel Disposal Landfill. The ERA lead regulatory agency is Ecology and EPA is the support agency. The ERA was categorized as non-time-critical, which required preparation of an engineering evaluation and cost analysis (EE/CA). The EE/CA was included in the ERA proposal. The EE/CA is a rapid, focused evaluation of available technologies using specific screening factors to assess feasibility, appropriateness, and cost. The ERA goal is to reduce the potential for any contaminant migration from the landfill to the soil column, groundwater, and Columbia River. Since the Sodium Dichromate Barrel Disposal Landfill is the only waste site within the operable unit, the removal action may be the final remediation of the 100-IU-4 Operable Unit. This ERA process started in March 1992. The ERA proposal went through a parallel review process with Westinghouse Hanford Company (WHC), DOE Richland Operations (RL), EPA, Ecology, and a 30-day public comment period. Ecology and EPA issued an Action Agreement Memorandum in March 1993 (Appendix A). The memorandum directed excavation of all anomalies and disposal of the collected materials at the Hanford Site Central Landfill. Primary field activities were completed by the end of April 1993. Final waste disposal of a minor quantity of hazardous waste was completed in July 1993.

    Earth science airborne missions play an important role in helping humans understand our climate. A challenge for airborne campaigns in contrast to larger NASA missions is that their relatively modest budgets do not permit the ground-up development of data management tools. These smaller missions generally consist of scientists whose primary focus is on the algorithmic and scientific aspects of the mission, which often leaves data management software and systems to be addressed as an afterthought. The Airborne Cloud Computing Environment (ACCE), developed by the Jet Propulsion Laboratory (JPL) to support Earth Science Airborne Program, is a reusable, multi-mission data system environment for NASA airborne missions. ACCE provides missions with a cloud-enabled platform for managing their data. The platform consists of a comprehensive set of robust data management capabilities that cover everything from data ingestion and archiving, to algorithmic processing, and to data delivery. Missions interact with this system programmatically as well as via browser-based user interfaces. The core components of ACCE are largely based on Apache Object Oriented Data Technology (OODT), an open source information integration framework at the Apache Software Foundation (ASF). Apache OODT is designed around a component-based architecture that allows for selective combination of components to create highly configurable data management systems. The diverse and growing community that currently contributes to Apache OODT fosters on-going growth and maturation of the software. ACCE's key objective is to reduce cost and risks associated with developing data management systems for airborne missions. Software reuse plays a prominent role in mitigating these problems. By providing a reusable platform based on open source software, ACCE enables airborne missions to allocate more resources to their scientific goals, thereby opening the doors to increased scientific discovery.

  9. PHARUS airborne SAR concept

    NASA Astrophysics Data System (ADS)

    Snoeij, Paul; Pouwels, Henk; Koomen, Peter J.; Hoogeboom, Peter

    1995-11-01

    PHARUS (phased array universal SAR) is an airborne SAR concept which is being developed in the Netherlands. The PHARUS system differs from other airborne SARs by the use of a phased array antenna, which provides both for the flexibility in the design as well as for a compact, light-weight instrument that can be carried on small aircraft. The concept allows for the construction of airborne SAR systems on a common generic basis but tailored to specific user needs and can be seen as a preparation for future spaceborne SAR systems using solid state transmitters with electronically steerable phased array antenna. The whole approach is aimed at providing an economic and yet technically sophisticated solution to remote sensing or surveying needs of a specific user. The solid state phased array antenna consists of a collection of radiating patches; the design flexibility for a large part resides in the freedom to choose the number of patches, and thereby the essential radar performance parameters such as resolution and swath width. Another consequence of the use of the phased array antenna is the system's compactness and the possibility to rigidly mount it on a small aircraft. The use of small aircraft of course considerably improves the cost/benefit ratio of the use of airborne SAR. Flight altitude of the system is flexible between about 7,000 and 40,000 feet, giving much operational freedom within the meteo and airspace control limits. In the PHARUS concept the airborne segment is complemented by a ground segment, which consists of a SAR processor, possibly extended by a matching image processing package. (A quick look image is available in real-time on board the aircraft.) The SAR processor is UNIX based and runs on easily available hardware (SUN station). Although the additional image processing software is available, the SAR processing software is nevertheless designed to be able to interface with commercially available image processing software, as well as being able

    Remote sensing is a process able to provide information about Earth to better understand Earth's processes and assist in monitoring Earth's resources. The Cloud Absorption Radiometer (CAR) is one remote sensing instrument dedicated to the cause of collecting data on anthropogenic influences on Earth as well as assisting scientists in understanding land-surface and atmospheric interactions. Landsat is a satellite program dedicated to collecting repetitive coverage of the continental Earth surfaces in seven regions of the electromagnetic spectrum. Combining these two aircraft and satellite remote sensing instruments will provide a detailed and comprehensive data collection able to provide influential information and improve predictions of changes in the future. This project acquired, interpreted, and created composite images from satellite data acquired from Landsat 4-5 Thematic Mapper (TM) and Landsat 7 Enhanced Thematic Mapper plus (ETM+). Landsat images were processed for areas covered by CAR during the Arctic Research of the Composition of the Troposphere from Aircraft and Satellites (ARCT AS), Cloud and Land Surface Interaction Campaign (CLASIC), Intercontinental Chemical Transport Experiment-Phase B (INTEXB), and Southern African Regional Science Initiative (SAFARI) 2000 missions. The acquisition of Landsat data will provide supplemental information to assist in visualizing and interpreting airborne and satellite imagery.

    Food allergy to peanut is a significant health problem, and there are reported allergic reactions to peanuts despite not eating or having physical contact with peanuts. It is presumed that an allergic reaction may have occurred from inhalation of airborne peanut allergens. The purpose of this study was to detect the possible concentrations of airborne peanut proteins for various preparations and during specific activities. Separate Ara h 1 and Ara h 2 monoclonal enzyme-linked immunosorbent assays and a polyclonal sandwich enzyme immunoassay for peanuts were used to detect the amount of airborne peanut protein collected using a Spincon Omni 3000 air collector (Sceptor Industries, Inc., Kansas City, MO) under different peanut preparation methods and situations. Air samples were measured for multiple peanut preparations and scenarios. Detectable amounts of airborne peanut protein were measured using a whole peanut immunoassay when removing the shells of roasted peanut. No airborne peanut allergen (Ara h 1 or Ara h 2) or whole peanut protein above the LLD was measured in any of the other peanut preparation collections. Ara h 1, Ara h 2, and polyclonal peanut proteins were detected from water used to boil peanuts. Small amounts of airborne peanut protein were detected in the scenario of removing shells from roasted peanuts; however, Ara h 1 and Ara h 2 proteins were unable to be consistently detected. Although airborne peanut proteins were detected, the concentration of airborne peanut protein that is necessary to elicit a clinical allergic reaction is unknown.

    The current data management practices for NASA airborne field projects have successfully served science team data needs over the past 30 years to achieve project science objectives, however, users have discovered a number of issues in terms of data reporting and format. The ICARTT format, a NASA standard since 2010, is currently the most popular among the airborne measurement community. Although easy for humans to use, the format standard is not sufficiently rigorous to be machine-readable, and there lacks a standard variable naming convention among the many airborne measurement variables. This makes data use and management tedious and resource intensive, and also create problems in Distributed Active Archive Center (DAAC) data ingest procedures and distribution. Further, most DAACs use metadata models that concentrate on satellite data observations, making them less prepared to deal with airborne data. There also exists a substantial amount of airborne data distributed by websites designed for science team use that are less friendly to users unfamiliar with operations of airborne field studies. A number of efforts are underway to help overcome the issues with airborne data discovery and distribution. The ICARTT Refresh Earth Science Data Systems Working Group (ESDSWG) was established to enable a platform for atmospheric science data providers, users, and data managers to collaborate on developing new criteria for the file format in an effort to enhance airborne data usability. In addition, the NASA Langley Research Center Atmospheric Science Data Center (ASDC) has developed the Toolsets for Airborne Data (TAD) to provide web-based tools and centralized access to airborne in situ measurements of atmospheric composition. This presentation will discuss the aforementioned challenges and attempted solutions in an effort to demonstrate how airborne data management can be improved to streamline data ingest and discoverability to a broader user community.

  17. Validation and applications of an expedited tablet friability method.

    The harmonized monograph on tablet friability test in United States Pharmacopeia (USP), European Pharmacopeia (Pharm. Eur.), and Japanese Pharmacopeia (JP) is designed to assess adequacy of mechanical strength of a batch of tablets. Currently, its potential applications in formulation development have been limited due to the batch requirement that is both labor and material intensive. To this end, we have developed an expedited tablet friability test method, using the existing USP test apparatus. The validity of the expedited friability method is established by showing that the friability data from the expedited method is not statistically different from those from the standard pharmacopeia method using materials of very different mechanical properties, i.e., microcrystalline cellulose and dibasic calcium phosphate dihydrate. Using the expedited friability method, we have shown that the relationship between tablet friability and tablet mechanical strength follows a power law expression. Furthermore, potential applications of this expedited friability test in facilitating systematic and efficient tablet formulation and tooling design are demonstrated with examples.

    2000-08-31

    The objective of Modeling for Airborne Contamination (referred to from now on as ''this report'') is to provide a documented methodology, along with supporting information, for estimating the release, transport, and assessment of dose to workers from airborne radioactive contaminants within the Monitored Geologic Repository (MGR) subsurface during the pre-closure period. Specifically, this report provides engineers and scientists with methodologies for estimating how concentrations of contaminants might be distributed in the air and on the drift surfaces if released from waste packages inside the repository. This report also provides dose conversion factors for inhalation, air submersion, and ground exposure pathways used to derive doses to potentially exposed subsurface workers. The scope of this report is limited to radiological contaminants (particulate, volatile and gaseous) resulting from waste package leaks (if any) and surface contamination and their transport processes. Neutron activation of air, dust in the air and the rock walls of the drift during the preclosure time is not considered within the scope of this report. Any neutrons causing such activation are not themselves considered to be ''contaminants'' released from the waste package. This report: (1) Documents mathematical models and model parameters for evaluating airborne contaminant transport within the MGR subsurface; and (2) Provides tables of dose conversion factors for inhalation, air submersion, and ground exposure pathways for important radionuclides. The dose conversion factors for air submersion and ground exposure pathways are further limited to drift diameters of 7.62 m and 5.5 m, corresponding to the main and emplacement drifts, respectively. If the final repository design significantly deviates from these drift dimensions, the results in this report may require revision. The dose conversion factors are further derived by using concrete of sufficient thickness to simulate the drift

    In order to evaluate the potential of airborne laser scanning for topographic mapping in Antarctica and to establish calibration/validation sites for NASA's Ice, Cloud and land Elevation Satellite (ICESat) altimeter mission, NASA, the U.S. National Science Foundation (NSF), and the U.S. Geological Survey (USGS) joined forces to collect high-resolution airborne laser scanning data.In a two-week campaign during the 2001-2002 austral summer, NASA's Airborne Topographic Mapper (ATM) system was used to collect data over several sites in the McMurdo Sound area of Antarctica (Figure 1a). From the recorded signals, NASA computed laser points and The Ohio State University (OSU) completed the elaborate computation/verification of high-resolution Digital Elevation Models (DEMs) in 2003. This article reports about the DEM generation and some exemplary results from scientists using the geomorphologic information from the DEMs during the 2003-2004 field season.

    Gelbard, Fred

    2004-02-03

    A method and system for inferring airborne contaminant concentrations in rooms without contaminant sensors, based on data collected by contaminant sensors in other rooms of a building, using known airflow interconnectivity data. The method solves a least squares problem that minimizes the difference between measured and predicted contaminant sensor concentrations with respect to an unknown contaminant release time. Solutions are constrained to providing non-negative initial contaminant concentrations in all rooms. The method can be used to identify a near-optimal distribution of sensors within the building, when then number of available sensors is less than the total number of rooms. This is achieved by having a system-sensor matrix that is non-singular, and by selecting that distribution which yields the lowest condition number of all the distributions considered. The method can predict one or more contaminant initial release points from the collected data.

    Broad Funding Opportunity Announcement Project: Makani Power is developing an Airborne Wind Turbine (AWT) that eliminates 90% of the mass of a conventional wind turbine and accesses a stronger, more consistent wind at altitudes of near 1,000 feet. At these altitudes, 85% of the country can offer viable wind resources compared to only 15% accessible with current technology. Additionally, the Makani Power wing can be economically deployed in deep offshore waters, opening up a resource which is 4 times greater than the entire U.S. electrical generation capacity. Makani Power has demonstrated the core technology, including autonomous launch, land, and power generation with an 8 meter wingspan, 20 kW prototype. At commercial scale, Makani Power aims to develop a 600 kW, 28 meter wingspan product capable of delivering energy at an unsubsidized cost competitive with coal, the current benchmark for low-cost power.

    Hurricane and Severe Storm Sentinel (HS3) is a NASA airborne field campaign aimed at better understanding the physical processes that control hurricane intensity change. HS3 will help answer questions related to the roles of environmental conditions and internal storm structures to storm intensification. Due to the nature of the questions that HS3 mission is addressing, it involves a variety of in-situ, satellite observations, airborne data, meteorological analyses, and simulation data. This variety of datasets presents numerous data management challenges for HS3. The methods used for airborne data management differ greatly from the methods used for space-borne data. In particular, metadata extraction, spatial and temporal indexing, and the large number of instruments and subsequent variables are a few of the data management challenges unique to airborne missions. A robust data system is required to successfully help HS3 scientist achieve their mission goals. Furthermore, the data system also needs to provide for data management that assists in broader use of HS3 data to enable future research activities. The Global Hydrology Resource Center (GHRC) is considering all these needs and designing a data system for HS3. Experience with past airborne field campaign puts GHRC in a good position to address HS3 needs. However, the scale of this mission along with science requirements separates HS3 from previous field campaigns. The HS3 data system will include automated services for geo-location, metadata extraction, discovery, and distribution for all HS3 data. To answer the science questions, the data system will include a visual data exploration tool that is fully integrated into the data catalog. The tool will allow visually augmenting airborne data with analyses and simulations. Satellite data will provide contextual information during such data explorations. All HS3 tools will be supported by an enterprise service architecture that will allow scaling, easy integration

    A meteorological overview of the Arctic Boundary Layer Expedition (ABLE 3A) flight series is presented. Synoptic analyses of mid-tropospheric circulation patterns are combined with isentropic back trajectory calculations to describe the long-range (400-3000 km) atmospheric transport mechanisms and pathways of air masses to the Arctic and sub-Arctic regions of North America during July and August 1988. Siberia and the northern Pacific Ocean were found to be the two most likely source areas for 3-day transport to the study areas in Alaska. Transport to the Barrow region was frequently influenced by polar vortices and associated short-wave troughs over the Arctic Ocean, while the Bethel area was most often affected by lows migrating across the Bering Sea and the Gulf of Alaska, as well as ridges of high pressure which built into interior Alaska. July 1988 was warmer and dryer than normal over much of Alaska. As a result, the 1988 Alaska fire season was one of the most active of the past decade. Airborne lidar measurements verified the presence of biomass burning plumes on many flights, often trapped in thin subsidence layer temperature inversions. Several cases of stratosphere/troposphere exchange were noted, based upon potential vorticity analyses and aircraft lidar data, especially in the Barrow region and during transit flights to and from Alaska.

    The Indian Space Research Organisation (ISRO) and the National Aeronautics and Space Administration (NASA) have jointly embarked on NASA-ISRO Synthetic Aperture Radar (NISAR) operating in L-band and S-band, which will map Earth's surface every 12 days. As a pre-cursor to the NISAR mission, ISRO is planning an airborne SAR (L&S band) which will deliver NISAR analogue data products to the science community. ISRO will develop all the hardware with the aim of adhering to system design aspects of NISAR to the maximum extent possible. It is a fully polarimetric stripmap SAR and can be operated in single, dual, compact, quasi-quad and full polarimetry modes. It has wide incidence angle coverage from 24°-77° with swath coverage from 5.5km to 15 km. Apart from simultaneous imaging operations, this system can also operate in standalone L/S SAR modes. This system is planned to operate from an aircraft platform with nominal altitude of 8000meters. Antenna for this SAR will be rigidly mounted to the aircraft, whereas, motion compensation will be implemented in the software processor to generate data products. Data products for this airborne SAR will be generated in slant & ground range azimuth dimension and geocoded in HDF5/Geotiff formats. This airborne SAR will help to prepare the Indian scientific community for optimum utilization of NISAR data. In-order to collect useful science data, airborne campaigns are planned from end of 2016 onwards.

  10. Airborne Particulate Threat Assessment

    2008-12-31

    Aerosol threat detection requires the ability to discern between threat agents and ambient background particulate matter (PM) encountered in the environment. To date, Raman imaging technology has been demonstrated as an effective strategy for the assessment of threat agents in the presence of specific, complex backgrounds. Expanding our understanding of the composition of ambient particulate matter background will improve the overall performance of Raman Chemical Imaging (RCI) detection strategies for the autonomous detection of airborne chemical and biological hazards. Improving RCI detection performance is strategic due to its potential to become a widely exploited detection approach by several U.S. government agencies. To improve the understanding of the ambient PM background with subsequent improvement in Raman threat detection capability, ChemImage undertook the Airborne Particulate Threat Assessment (APTA) Project in 2005-2008 through a collaborative effort with the National Energy Technology Laboratory (NETL), under cooperative agreement number DE-FC26-05NT42594. During Phase 1 of the program, a novel PM classification based on molecular composition was developed based on a comprehensive review of the scientific literature. In addition, testing protocols were developed for ambient PM characterization. A signature database was developed based on a variety of microanalytical techniques, including scanning electron microscopy, FT-IR microspectroscopy, optical microscopy, fluorescence and Raman chemical imaging techniques. An automated particle integrated collector and detector (APICD) prototype was developed for automated collection, deposition and detection of biothreat agents in background PM. During Phase 2 of the program, ChemImage continued to refine the understanding of ambient background composition. Additionally, ChemImage enhanced the APICD to provide improved autonomy, sensitivity and specificity. Deliverables included a Final Report detailing our

    1996-01-01

    Two new technologies, the FASTexpedition and Remote FAST, have been developed that provide remote, 3D (three dimensional), high resolution, dynamic, interactive viewing of scientific data. The FASTexpedition permits one to access scientific data from the World Wide Web, take guided expeditions through the data, and continue with self controlled expeditions through the data. Remote FAST permits collaborators at remote sites to simultaneously view an analysis of scientific data being controlled by one of the collaborators. Control can be transferred between sites. These technologies are now being used for remote collaboration in joint university, industry, and NASA projects. Also, NASA Ames Research Center has initiated a project to make scientific data and guided expeditions through the data available as FASTexpeditions on the World Wide Web for educational purposes. Previously, remote visualization of dynamic data was done using video format (transmitting pixel information) such as video conferencing or MPEG (Motion Picture Expert Group) movies on the Internet. The concept for this new technology is to send the raw data (e.g., grids, vectors, and scalars) along with viewing scripts over the Internet and have the pixels generated by a visualization tool running on the viewers local workstation. The visualization tool that is currently used is FAST (Flow Analysis Software Toolkit). The advantages of this new technology over using video format are: (1) The visual is much higher in resolution (1280x1024 pixels with 24 bits of color) than typical video format transmitted over the network. (2) The form of the visualization can be controlled interactively (because the viewer is interactively controlling the visualization tool running on his workstation). (3) A rich variety of guided expeditions through the data can be included easily. (4) A capability is provided for other sites to see a visual analysis of one site as the analysis is interactively performed. Control of

    2016-04-01

    Oceanographic research cruises are complex affairs, typically requiring an extensive effort to secure the funding, plan the experiment, and mobilize the field party. Yet cruises are not typically published online as first-class digital objects with persistent, citable identifiers linked to the scientific literature. The Rolling Deck to Repository (R2R; info@rvdata.us) program maintains a master catalog of oceanographic cruises for the United States research fleet, currently documenting over 6,000 expeditions on 37 active and retired vessels. In 2015, R2R started routinely publishing a Digital Object Identifier (DOI) for each completed cruise. Cruise DOIs, in turn, are linked to related persistent identifiers where available including the Open Researcher and Contributor ID (ORCID) for members of the science party, the International Geo Sample Number (IGSN) for physical specimens collected during the cruise, the Open Funder Registry (FundRef) codes that supported the experiment, and additional DOIs for datasets, journal articles, and other products resulting from the cruise. Publishing a persistent identifier for each field expedition will facilitate interoperability between the many different repositories that hold research products from cruises; will provide credit to the investigators who secured the funding and carried out the experiment; and will facilitate the gathering of fleet-wide altmetrics that demonstrate the broad impact of oceanographic research.

    waited as the OBS traveled at around 40 meters a minute to the surface. The entire retrieval process could take anywhere from 2 hours to 4 hours for each seismometer. The third retrieval leg was aboard the Research Vessel Atlantis and utilized the submersible Remotely Operated Vehicle (ROV) Jason. The ROV was used to recover 12 of the 30 seismometers for this last retrieval mission. The final three legs were OBS deployments conducted with the assistance of the Research Vessel Oceanus. The seismometers were dropped in a desired location and allowed to sink to the ocean bottom. The ship would then obtain an exact location of the deployed seismometer using the same method described above. Participants will share their newfound knowledge of everyday life at sea and learning about the science behind deploying and retrieving OBSs. Even though participants were on different legs of the 2013 Cascadia Expedition, they all shared similar experiences. Some of the most memorable moments include amazing food, learning about the different components of an ocean bottom seismometer, and some of the most beautiful blue water.

  8. ISS Potable Water Quality for Expeditions 26 through 30

    NASA Technical Reports Server (NTRS)

    Straub, John E., II; Plumlee, Debrah K.; Schultz, John R.; McCoy, J. Torin

    2012-01-01

    International Space Station (ISS) Expeditions 26-30 spanned a 16-month period beginning in November of 2010 wherein the final 3 flights of the Space Shuttle program finished ISS construction and delivered supplies to support the post-shuttle era of station operations. Expedition crews relied on several sources of potable water during this period, including water recovered from urine distillate and humidity condensate by the U.S. water processor, water regenerated from humidity condensate by the Russian water recovery system, and Russian ground-supplied potable water. Potable water samples collected during Expeditions 26-30 were returned on Shuttle flights STS-133 (ULF5), STS-134 (ULF6), and STS-135 (ULF7), as well as Soyuz flights 24-27. The chemical quality of the ISS potable water supplies continued to be verified by the Johnson Space Center s Water and Food Analytical Laboratory (WAFAL) via analyses of returned water samples. This paper presents the chemical analysis results for water samples returned from Expeditions 26-30 and discusses their compliance with ISS potable water standards. The presence or absence of dimethylsilanediol (DMSD) is specifically addressed, since DMSD was identified as the primary cause of the temporary rise and fall in total organic carbon of the U.S. product water that occurred in the summer of 2010.

  14. Improving the regulation of carcinogens by expediting cancer potency estimation.

    PubMed

    Hoover, S M; Zeise, L; Pease, W S; Lee, L E; Hennig, M P; Weiss, L B; Cranor, C

    1995-04-01

    The statutory language of the Safe Drinking Water and Toxic Enforcement Act of 1986 (Proposition 65; California Health and Safety Code 25249.5 et seq.) encourages rapid adoption of "no significant risk levels" (NSRLs), intakes associated with estimated cancer risks of no more than 1 in 100,000. Derivation of an NSRL for a carcinogen listed under Proposition 65 requires the development of a cancer potency value. This paper discusses the methodology for the derivation of cancer potencies using an expedited procedure, and provides potency estimates for a number of agents listed as carcinogens under Proposition 65. To derive expedited potency values, default risk assessment methods are applied to data sets selected from an extensive tabulation of animal cancer bioassays according to criteria used by regulatory agencies. A subset of these expedited values is compared to values previously developed by regulatory agencies using conventional quantitative risk assessment and found to be in good agreement. Specific regulatory activities which could be facilitated by adopting similar expedited procedures are identified. PMID:7597261

  17. A solar power system for an early Mars expedition

    NASA Technical Reports Server (NTRS)

    Mckissock, Barbara I.; Kohout, Lisa L.; Schmitz, Paul C.

    1990-01-01

    As NASA looks at missions that will expand human presence in the solar system, the power requirements for such missions need to be defined, developed and analyzed. One mission under consideration consists of a 40 day manned Mars surface expedition to perform science experiments. The mission time was centered around an aerocentric longitude (Ls) of 90 deg to lessen the probability of an occurrence of a local or planetary dust storm. The mission site was arbitrarily located at the Martian equator. The power requirements were assumed to be 40 kWe for life support and experiment power during the Martian day and 20 kWe for life support during the Martian night. A solar energy system consisting of roll-out amorphous silicon arrays and a hydrogen-oxygen regenerative fuel cell energy storage system was chosen for the study. The power available from a roll-out array, when plotted against time, approaches a cosine-like curve and depends on both array area and the amount of solar irradiance impinging on its horizontal surface. The array is sized to provide at least 20 KWe when the sun is 12.5 deg above the horizon and ramp up to 140 kWe peak power at Martian noon. In this configuration, the array is capable of supplying 40 KWe continuously to the user for the majority of the Martian day while supplying the excess energy to the electrolyzer portion of the energy storage system. A roll-out, pumped loop radiator system is used to dissipate the waste heat produced by the fuel cell. The power management and distribution system inverts the power from the individual solar array sub-modules and the fuel cell stacks and connects them to a 440 VAC single phase 20 kHz main bus. The total power system is comprised of 80 individual solar array modules with an integral bus and three energy storage modules consisting of fuel cell and electrolyzer stacks, reactant storage tanks, and a roll-out radiator. Power system mass, stowed volume, and deployed area were determined. Day/night power

    Real time lightning observations have proven to be useful for advanced warning and now-casting of severe weather events. In anticipation of the launch of the Geostationary Lightning Mapper (GLM) onboard GOES-R that will provide continuous real time observations of total (both cloud and ground) lightning, the Fly's Eye GLM Simulator (FEGS) is in production. FEGS is an airborne instrument designed to provide cal/val measurements for GLM from high altitude aircraft. It consists of a 5 x 5 array of telescopes each with a narrow passband filter to isolate the 777.4 nm neutral oxygen emission triplet radiated by lightning. The telescopes will measure the optical radiance emitted by lightning that is transmitted through the cloud top with a temporal resolution of 10 μs. When integrated on the NASA ER-2 aircraft, the FEGS array with its 90° field-of-view will observe a cloud top area nearly equal to a single GLM pixel. This design will allow FEGS to determine the temporal and spatial variation of light that contributes to a GLM event detection. In addition to the primary telescope array, the instrument includes 5 supplementary optical channels that observe alternate spectral emission features and will enable the use of FEGS for interesting lightning physics applications. Here we present an up-to-date summary of the project and a description of its scientific applications.

    The University of Alabama in Huntsville (UAH), in collaboration with the Global Hydrology Resource Center, a NASA Earth Science Data Center, has provided information management for a number of NASA Airborne Field campaigns, both hurricane science investigations and satellite instrument validation. Effective field campaign management requires communication and coordination tools, including utilities for personnel to upload and share flight plans, weather forecasts, a variety of mission reports, preliminary science data, and personal photos. Beginning with the Genesis and Rapid Intensification Processes (GRIP) hurricane field campaign in 2010, we have provided these capabilities via a Drupal-based collaboration portal. This portal was reused and modified for the Midlatitude Continental Convective Clouds Experiment (MC3E), part of the Global Precipitation Measurement mission ground validation program. An end goal of these development efforts is the creation of a Drupal profile for field campaign management. This presentation will discuss experiences with Drupal in developing and using these collaboration portals. Topics will include Drupal modules used, advantages and disadvantages of working with Drupal in this context, and how the science teams used the portals in comparison with other communication and collaboration tools.

    2004-01-01

    The main purpose of this award was to supply a platform for the airborne measurements of gases associated with the CO2 Budget and Regional Airborne Study (COBRA). The original program was to consist of three field programs: the first was to be in 1999, the second in 2000, and the third in 2001. At the end of the second field program, it was agreed that the science could better be served by making the measurements in northern Brazil, rather than in North America. The final North American program would be postponed until after two field programs in Brazil. A substantial amount of effort was diverted into making plans and preparations for the Brazil field programs. The Brazil field programs were originally scheduled to take place in the Fall of 2002 and Spring of 2003. Carrying out the field program in Brazil was going to logistically much more involved than a program in the US. Shipping of equipment, customs, and site preparations required work to begin many months prior to the actual measurement program. Permission to fly in that country was also not trivial and indeed proved to be a major obstacle. When we were not able to get permission to fly in Brazil for the 2002 portion of the experiment, the program was pushed back to 2003. When permission by the Brazilian government was not given in time for a Spring of 2003 field program, the experiment was postponed again to begin in the Fall of 2003.

    Earth science research often requires crustal deformation measurements at a variety of time scales, from seconds to decades. Although satellites have been used for repeat-track interferometric (RTI) synthetic-aperture-radar (SAR) mapping for close to 20 years, RTI is much more difficult to implement from an airborne platform owing to the irregular trajectory of the aircraft compared with microwave imaging radar wavelengths. Two basic requirements for robust airborne repeat-pass radar interferometry include the ability to fly the platform to a desired trajectory within a narrow tube and the ability to have the radar beam pointed in a desired direction to a fraction of a beam width. Uninhabited Aerial Vehicle Synthetic Aperture Radar (UAVSAR) is equipped with a precision auto pilot developed by NASA Dryden that allows the platform, a Gulfstream III, to nominally fly within a 5 m diameter tube and with an electronically scanned antenna to position the radar beam to a fraction of a beam width based on INU (inertial navigation unit) attitude angle measurements.

  13. Airborne Laser Polar Nephelometer

    Grams, Gerald W.

    1973-01-01

    A polar nephelometer has been developed at NCAR to measure the angular variation of the intensity of light scattered by air molecules and particles. The system has been designed for airborne measurements using outside air ducted through a 5-cm diameter airflow tube; the sample volume is that which is common to the intersection of a collimated source beam and the detector field of view within the airflow tube. The source is a linearly polarized helium-neon laser beam. The optical system defines a collimated field-of-view (0.5deg half-angle) through a series of diaphragms located behind a I72-mm focal length objective lens. A photomultiplier tube is located immediately behind an aperture in the focal plane of the objective lens. The laser beam is mechanically chopped (on-off) at a rate of 5 Hz; a two-channel pulse counter, synchronized to the laser output, measures the photomultiplier pulse rate with the light beam both on and off. The difference in these measured pulse rates is directly proportional to the intensity of the scattered light from the volume common to the intersection of the laser beam and the detector field-of-view. Measurements can be made at scattering angles from 15deg to 165deg with reference to the direction of propagation of the light beam. Intermediate angles are obtained by selecting the angular increments desired between these extreme angles (any multiple of 0.1deg can be selected for the angular increment; 5deg is used in normal operation). Pulses provided by digital circuits control a stepping motor which sequentially rotates the detector by pre-selected angular increments. The synchronous photon-counting system automatically begins measurement of the scattered-light intensity immediately after the rotation to a new angle has been completed. The instrument has been flown on the NASA Convair 990 airborne laboratory to obtain data on the complex index of refraction of atmospheric aerosols. A particle impaction device is operated simultaneously

    . These results encouraged us to apply these methods to airborne geophysical data sets from the United Mexican States. One survey was targeted to provide additional data for advanced groundwater modeling in remote areas of the karstic plateau of Yucatan. Within the other project a sustainable source of water supply for a small settlement on the isolated island of Socorro, 700 km off the Mexican main coast had to be detected. At both survey areas no accurate elevation models or area-wide information about vegetation heights where available before the airborne geophysical survey. The results of these investigations will be presented. From an evaluation of the results it can be concluded that the use of laser altimetry not only provides essential information about the ground clearance of the geophysical instruments but also increases the benefit of the airborne survey for the client by delivering additional information about the survey area. It is clear that the accuracy of the resulting data cannot compete with a high resolution laser scanning survey. However in areas where such information is not available an obvious additional benefit can be achieved without the need to spend money for additional survey campaigns. Currently further studies are launched to investigate the possibility to increase the accuracy of the altitude data by determining roll and pitch of the helicopter by the use of differentially corrected multiple L1/L2 band GPS receiver mounted at fixed positions on the helicopter platform. The above study was partly financed by the Austrian Science Fund, Xplore (L524-N10) project.

  15. SOFIA'S Challenge: Scheduling Airborne Astronomy Observations

    NASA Technical Reports Server (NTRS)

    Frank, Jeremy

    2005-01-01

    The Stratospheric Observatory for Infrared Astronomy (SOFIA) is NASA's next generation airborne astronomical observatory, and will commence operations in 2005. The facility consists of a 747-SP modified to accommodate a 2.5 meter telescope. SOFIA is expected to fly an average of 140 science flights per year over its 20 year lifetime. Depending on the nature of the instrument used during flight, 5-15 observations per flight are expected. The SOFIA telescope is mounted aft of the wings on the port side of the aircraft and is articulated through a range of 20deg to 60deg of elevation. The telescope has minimal lateral flexibility; thus, the aircraft must turn constantly to maintain the telescope's focus on an object during observations. A significant problem in future SOFIA operations is that of scheduling flights in support of observations. Investigators are expected to propose small numbers of observations, and many observations must be grouped together to make up single flights. Flight planning for the previous generation airborne observatory, the Kuiper Airborne Observatory (KAO), was done by hand; planners had to choose takeoff time, observations to perform, and decide on setup-actions (called "dead-legs") to position the aircraft prior to observing. This task frequently required between 6-8 hours to plan one flight The scope of the flight planning problem for supporting GI observations with the anticipated flight rate for SOFIA makes the manual approach for flight planning daunting. In response, we have designed an Automated Flight Planner (AFP) that accepts as input a set of requested observations, designated flight days, weather predictions and fuel limitations, and searches automatically for high-quality flight plans that satisfy all relevant aircraft and astronomer specified constraints. The AFP can generate one candidate flight plan in 5-10 minutes, of computation time, a feat beyond the capabilities of human flight planners. The rate at which the AFP can

    The general theme for the workshop revolved around global environmental change. Over 170 individuals participated in the presentations and ensuing discussions about the many agency activities using airborne platforms and sensors in support of the U.S. Global Change Research Program (GCRP). The U.S. GCRP was developed as a central component of the U.S. Government's approach to global change and its contribution to worldwide efforts. An all-encompassing U.S. plan was developed by the Committee on Earth and Environmental Sciences (CEES), which continues as the interagency coordinating group for the program. The U.S. GCRP was established as a Presidential initiative in the FY90 budget, making it a particularly relevant topic for the workshop. The following are presented in the appendices: (1) final agenda and list of registrants; (2) final list of poster presenters; (3) steering group luncheon participants; (4) the draft resolution; and (5) selected handouts.

    The results of terrain mapping experiments utilizing the National Aeronautics and Space Administration (NASA) Airborne Oceanographic Lidar (AOL) over forested areas are presented. The flight tests were conducted as part of a joint NASA/U.S. Army Corps of Engineers (CE) investigation aimed at evaluating the potential of an airborne laser ranging system to provide cross-sectional topographic data on flood plains that are difficult and expensive to survey using conventional techniques. The data described in this paper were obtained in the Wolf River Basin located near Memphis, TN. Results from surveys conducted under winter 'leaves off' and summer 'leaves on' conditions, aspects of day and night operation, and data obtained from decidous and coniferous tree types are compared. Data processing techniques are reviewed. Conclusions relative to accuracy and present limitations of the AOL, and airborne lidar systems in general, to terrain mapping over forested areas are discussed.

    Thermal gradient diffusion cloud chambers (TGDCC) are used to determine the concentrations of cloud condensation nuclei (CCN) with critical supersaturations greater than or equal to about 0.2%. The CCN concentrations measured with the airborne IHC were lower than theoretically predicted by factors ranging between 7.9 and 9.0. The CCN concentrations measured with the airborne IHC were lower than the concentrations measured with the larger laboratory IHC's by factors ranging between 3.9 and 7.5. The bounds of the supersaturation ranges of the airborne IHC and the CSU-Mee TGDCC do not overlap. Nevertheless, the slopes of the interpolated data between the bounds agree favorably with the theoretical slopes.

    2009-04-01

    EUFAR, EUropean Facilities for Airborne Research, is an FP7 project (http://www.eufar.net) funded by the European Commission with 33 partners that aims at providing and improving the access to European airborne facilities (i.e. aircraft, airborne instruments, data processing centres) for researchers in environmental and geo-sciences through Networking Activities, Transnational Access and Joint Research Activities. This paper reports on the training opportunities within EUFAR for European researchers. In EUFAR three types of training opportunities are offered: 1) Participate in training courses (ET-TC) 2) Join an existing field campaign (ET-EC) 3) Participate in the design of a new field campaign (ET-TA), in the frame of EUFAR Transnational Access and tutored by more experienced researchers. During the 4-year EUFAR project (2008-2012), 4 training courses covering the complete chain from acquisition to interpretation of airborne data and images will be organised during spring/summer for early-stage researchers as well as university lecturers (new in FP7 EUFAR) in airborne research. The training courses will have an equal focus on theory and practical training/demonstration and each training course will be accompanied by a "student" airborne field campaign. Participants will be trained by top-class scientists, aircraft and/or instrument operators and each participant will get the opportunity to design his/her own experiment and to participate to that flight experiment. Furthermore, researchers have the opportunity to join an existing field campaign and work with more experienced researchers, aircraft and/or instrument operators. The list of airborne field campaigns open to join and the eligibility criteria, can be consulted at the EUFAR website. Finally, researchers have the opportunity to participate in the design of a new field campaign in the frame of EUFAR Transnational Access (TA). TA provides access to either aircraft or instrumentation that are not otherwise

    Pertussis is a contagious, acute respiratory illness caused by the bacterial pathogen Bordetella pertussis. Although it is widely believed that transmission of B. pertussis occurs via aerosolized respiratory droplets, no controlled study has ever documented airborne transmission of pertussis. We set out to determine if airborne transmission occurs between infected and naive animals, utilizing the baboon model of pertussis. Our results showed that 100% of exposed naive animals became infected even when physical contact was prevented, demonstrating that pertussis transmission occurs via aerosolized respiratory droplets.

    1981-07-01

    For a number of years, concerns have been raised about the length of time and the complexity involved in obtaining required permits in order to develop the geothermal resource at the Geysers. Perhaps the most important factor is jurisdiction. At the Geysers, all three levels of government - local, state, and federal - exercise significant authority over various aspects of geothermal development. In addition, several agencies within each governmental level play an active role in the permitting process. The present study is concerned primarily with the local permitting process, and the ways in which this process could be expedited. This report begins by looking at the local role in the overall permitting process, and then reviews the findings and conclusions that have been reached in other studies of the problem. This is followed by a case study evaluation of recent permitting experience in the four Geysers-Calistoga KGRA counties, and the report concludes by outlining several approaches to expediting the local permitting process.

    1996-12-31

    California`s Expedited Remedial Action Program (ERAP) created a comprehensive program that promotes an equitable and expedited approach for redevelopment of properties contaminated with hazardous substances. This bill embodies an emerging trend in environmental policy that permits flexibility, cooperation and creativity without compromising protection to public health or the environment. Within the California Environmental Protection Agency, the Department of Toxic Substances Control (DTSC) is promoting a number of programs to facilitate the restoration of contaminated properties as part of its Brownfields initiative. ERAP represents a potentially more efficient process to remediate sites by minimizing economic risks through a clearly identified liability scheme, indemnifying future owners through a covenant not to sue, and providing risk based cleanups that are based on the permanent use of the site.

    1995-12-31

    In California, the California Environmental Protection Agency (Cal/EPA) has developed a more equitable and expedited approach for the redevelopment of sites contaminated with hazardous substances. Senate Bill 923 enacted in 1994, established the Expedited Remedial Action Program (ERAP) under Chapter 6.85 of the California Health and Safety Code. This bill responds to a nationwide demand to reform Superfund laws and promote the restoration of blighted and contaminated parcels--often referred to as Brownfields. The program was designed as an alternative to CERCLA, which has come under criticism for being inefficient, unfair and restricting opportunities for effective cleanups. Cal/EPA`s Department of Toxic Substances Control will implement this pilot program. This pilot program, which will eventually comprise 30 sites, provides incentives for voluntary remediation by addressing key economic issues associated with the remediation and redevelopment of contaminated properties.

    The Expedited Technology Demonstration Project Plan, MWNT Revised Baseline 3.0, replaces and significantly modifies the current baseline. The revised plan will focus efforts specifically on the demonstration of an integrated Molten Salt Oxidation (MSO) system. In addition to the MSO primary unit, offgas, and salt recycle subsystems, the demonstrations will include the generation of robust final forms from process mineral residues. A simplified process flow chart for the expedited demonstration is shown. To minimize costs and to accelerate the schedule for deployment, the integrated system will be staged in an existing facility at LLNL equipped to handle hazardous and radioactive materials. The MSO systems will be activated in FY97, followed by the activation of final forms in FY98.

    During the twelve month span of Expeditions 16 and 17 beginning October of 2007, the chemical quality of the potable water onboard the International Space Station (ISS) was verified safe for crew consumption through the return and chemical analysis of water samples by the Water and Food Analytical Laboratory (WAFAL) at Johnson Space Center (JSC). Reclaimed cabin humidity condensate and Russian ground-supplied water were the principle sources of potable water and for the first time, European groundsupplied water was also available. Although water was transferred from Shuttle to ISS during Expeditions 16 and 17, no Shuttle potable water was consumed during this timeframe. A total of 12 potable water samples were collected using U.S. hardware during Expeditions 16 and 17 and returned on Shuttle flights 1E (STS122), 1JA (STS123), and 1J (STS124). The average sample volume was sufficient for complete chemical characterization to be performed. The results of JSC chemical analyses of these potable water samples are presented in this paper. The WAFAL also received potable water samples for analysis from the Russian side collected inflight with Russian hardware, as well as preflight samples of Rodnik potable water delivered to ISS on Russian Progress vehicles 28 to 30. Analytical results for these additional potable water samples are also reported and discussed herein. Although the potable water supplies available during Expeditions 16 and 17 were judged safe for crew consumption, a recent trending of elevated silver levels in the SVOZV water is a concern for longterm consumption and efforts are being made to lower these levels.

    The Lewis and Clark expedition crossed the Continental Divide in 1805 on the way west to the Pacific Ocean. Based on journal entries, members of the expedition probably encountered two species of resident salmonids and four of the six species of anadromous salmonids and steelhead (Family Salmonidae, genus Oncorhynchus). The salmonid species were called common salmon (now known as Chinook salmon O. tshawytscha), red char (sockeye salmon O.nerka) white salmon trout (coho salmon [also known as silver salmon] O. kisutch), salmon trout (steelhead O. mykiss), and spotted trout (cutthroat trout O. clarkii). There was no evidence of the expedition encountering pink salmon O. gorbuscha, chum salmon O. keta, or species of true char Salvelinus spp. Common fishes procured from Indian tribes living along the lower Columbia River included eulachon Thaleichthys pacificus and white sturgeon Acipenser transmontanus. The identity of three additional resident freshwater species is questionable. Available descriptions suggest that what they called mullet were largescale sucker Catastomus macrocheilus, and that chubb were peamouth Mylocheilus caurinus. The third questionable fish, which they called bottlenose, was probably mountain whitefish Prosopium williamsoni, although there is no evidence that the species was observed in the Columbia River drainage. Missing from the species list were more than 20 other fishes known to Sahaptin-speaking people from the mid-Columbia region. More complete documentation of the icthyofauna of the Pacific Northwest region did not occur until the latter half of the 19th century. However, journals from the Lewis and Clark expedition provide the first documentation of Columbia River fishes.

    Observations of the gabbroic layers of untectonized ocean crust are essential to test theoretical models of the accretion of new crust at mid-ocean ridges. Integrated Ocean Drilling Program (IODP) Expedition 335 ("Superfast Spreading Rate Crust 4") returned to Ocean Drilling Program (ODP) Hole 1256D with the intention of deepening this reference penetration of intact ocean crust a significant distance (~350 m) into cumulate gabbros. Three earlier cruises to Hole 1256D (ODP 206, IODP 309/312) have drilled through the sediments, lavas, and dikes and 100 m into a complex dike-gabbro transition zone. Operations on IODP Expedition 335 proved challenging throughout, with almost three weeks spent re-opening and securing unstable sections of the hole. When coring commenced, the comprehensive destruction of the coring bit required further remedial operations to remove junk and huge volumes of accumulated drill cuttings. Hole-cleaning operations using junk baskets were successful, and they recovered large irregular samples that document a hitherto unseen sequence of evolving geological conditions and the intimate coupling between temporally and spatially intercalated intrusive, hydrothermal, contact-metamorphic, partial melting, and retrogressive processes. Hole 1256D is now clean of junk, and it has been thoroughly cleared of the drill cuttings that hampered operations during this and previous expeditions. At the end of Expedition 335, we briefly resumed coring before undertaking cementing operations to secure problematic intervals. To ensure the greatest scientific return from the huge efforts to stabilize this primary ocean lithosphere reference site, it would be prudent to resume the deepening of Hole 1256D in the nearest possible future while it is open to full depth. doi:10.2204/iodp.sd.13.04.2011

The primary objective of the STS-97 mission was the delivery, assembly, and activation of the U.S. electrical power system onboard the International Space Station (ISS). The electrical power system, which is built into a 73-meter (240-foot) long solar array structure consists of solar arrays, radiators, batteries, and electronics. The entire 15.4-metric ton (17-ton) package is called the P6 Integrated Truss Segment, and is the heaviest and largest element yet delivered to the station aboard a space shuttle. The electrical system will eventually provide the power necessary for the first ISS crews to live and work in the U.S. segment. The STS-97 crew of five launched aboard the Space Shuttle Orbiter Endeavor on November 30, 2000 for an 11 day mission.

    On April 19, 2008 the crew of Expedition 16 left the International Space Station and returned to earth via their Soyuz TMA-11 capsule after 192 days on orbit. Their capsule experienced the second consecutive and third ballistic reentry in the last 10 TMA recoveries and landed approximately 260 miles (420 km) from the prime landing site. Issues: The purpose of this presentation will be to describe, not only the typical medical operational challenges faced by Flight Surgeons recovering a long duration crew from space, but also address the unique challenges that existed with the Expedition 16 landing and crew recovery. Nominal Soyuz recovery challenges include remote recovery sites with crew exposures to sleep shifting and fatigue, dehydration, hypothermia and hyperthermia, and rotational, sustained, and impact g-forces. These environmental factors coupled with the patho-physiologic neuro-vestibular and orthostatic intolerance changes that occur secondary to the crews reintroduction into the earth s gravity field will be detailed. Additional challenges that were unique to this expedition included a ballistic reentry with higher g-loads, the presence of fire outside of the capsule on landing, a contingency medical event of a ground support personnel, and loss of communications with the crew just prior to landing and during recovery operations. Conclusions: In spite of these unique challenges the Russian Search and Rescue Forces and Medical Support personnel along with U.S. Medical Support performed well together. Possible improvements in training and coordination will be discussed.

    IODP Expedition 339 had two inter-related objectives to recover continuous sedimentary sequences for: (i) studying the Contourite Depositional System formed by the MOW; and (ii) reconstructing North Atlantic climate variability on orbital and suborbital time scales. This Elsevier Virtual Special Issue (VSI) "Mediterranean Outflow" is comprised of two volumes that are roughly divided along these lines with Marine Geology devoted to (i) and Global and Planetary Change to (ii), although some papers overlap the two themes. The Marine Geology volume contains 9 contributions addressing specific aspects of IODP Expedition 339 related to contourite deposits including sedimentology, seismic interpretation, stratigraphy, physical properties, downhole logging and ichnofacies (Hernández-Molina et al., 2015; Lofi et al., 2015; Ducassou et al., 2015; Alonso et al., 2015; Takashimizu et al., 2016; Nishida, 2015; Dorador and Rodríguez-Tovar, 2015a, 2015b; Kaboth et al., 2015). The Global and Planetary Change volume consists of 18 papers described below, highlighting paleoclimatic results from sites drilled on the SW Iberian Margin and in the Gulf of Cadiz. The two volumes provide a sample of emerging results of Expedition 339 and foretell of the promising research yet to come.

    Over the past few years the possible contribution of acid rain to the problem of forest decline has been a cause of increasing public concern. Research has begun to determine whether airborne chemicals are causing or contributing to visible damage and mortality in eastern spruce-fir and sugar maple forests and to changes in tree growth, usually without visible symptoms, in other parts of North America. This paper describes some of the complex biological relationships that determine health and productivity of forests and that make it difficult to distinguish effects of airborne chemicals from effects of natural stress. It describes four major research approaches for assessment of the effects of airborne chemicals on forests, and it summarizes current understanding of the known and possible effects of airborne chemicals on forest trees in North America and Europe. It also briefly describes the major air quality and forest health research programs in North America, and it assesses how ell these programs are likely to meet information needs during the coming decade. 69 references, 2 figures, 1 table.

    The U.S. Environmental Protection Agency sampled air in 49 government-owned buildings (six buildings with no asbestos-containing material, six buildings with asbestos-containing material in generally good condition, and 37 buildings with damaged asbestos-containing material). This is the most comprehensive study to date of airborne asbestos levels in U.S. public buildings during normal building activities. The air outside each building was also sampled. Air samples were analyzed by transmission electron microscopy using a direct transfer preparation technique. The results show an increasing trend in average airborne asbestos levels; outdoor levels are lowest and levels in buildings with damaged asbestos-containing material are highest. However, the measured levels and the differences between indoors and outdoors and between building categories are small in absolute magnitude. Comparable studies from Canada and the UK, although differing in their estimated concentrations, also conclude that while airborne asbestos levels may be elevated in buildings that contain asbestos, levels are generally low. This conclusion does not eliminate the possibility of higher airborne asbestos levels during maintenance or renovation that disturbs the asbestos-containing material.

    Teachers in today s classrooms need to find creative ways to connect students with science, technology, engineering, mathematics (STEM) experts. These STEM experts can serve as role models and help students think about potential future STEM careers. They can also help reinforce academic knowledge and skills. The cost of transportation restricts teachers ability to take students on field trips exposing them to outside experts and unique learning environments. Additionally, arranging to bring in guest speakers to the classroom seems to happen infrequently, especially in schools in rural areas. The Expedition Earth and Beyond (EEAB) Program [1], facilitated by the Astromaterials Research and Exploration Science (ARES) Directorate Education Program at the NASA Johnson Space Center has created a way to enable teachers to connect their students with STEM experts virtually. These virtual connections not only help engage students with role models, but are also designed to help teachers address concepts and content standards they are required to teach. Through EEAB, scientists are able to actively engage with students across the nation in multiple ways. They can work with student teams as mentors, participate in virtual student team science presentations, or connect with students through Classroom Connection Distance Learning (DL) Events.

    2009-05-01

    Airborne networks are envisioned to provide interconnectivity for terrestial and space networks by interconnecting highly mobile airborne platforms. A number of military applications are expected to be used by the operator, and all these applications require proper routing security support to establish correct route between communicating platforms in a timely manner. As airborne networks somewhat different from traditional wired and wireless networks (e.g., Internet, LAN, WLAN, MANET, etc), security aspects valid in these networks are not fully applicable to airborne networks. Designing an efficient security scheme to protect airborne networks is confronted with new requirements. In this paper, we first identify a candidate routing architecture, which works as an underlying structure for our proposed security scheme. And then we investigate the vulnerabilities and attack models against routing protocols in airborne networks. Based on these studies, we propose an integrated security solution to address routing security issues in airborne networks.

    The Arctic Boundary Layer Expedition (ABLE) 3B was conducted to determine the summertime tropospheric distribution, sources, and sinks of important trace gas and aerosol species over the wetlands and boreal forests of central and eastern Canada. Isentropic trajectories and analyzed midtropospheric circulation patterns were used to group flights according to the transport histories of polar, midlatitude, or tropical air masses which were sampled. These data were then divided into bands of potential temperature levels representing the low, middle, and maximum aircraft altitudes to assess the effects of both local and long distance transport and natural and man-made pollutants to the measured chemical species. Detailed case studies are provided to depict the complex three-dimensional airflow regimes that transported air with differing chemical signatures to the study area. Mission 6 details the large-scale movement of smoke in the generally prevailing west to northwesterly airflow that was observed on the majority of flights. Mission 1 analyzes the horizontal and vertical motions of maritime Pacific air in the upper troposphere that was routinely mixed downward to the aircraft altitude. Finally, mission 14 tracks the far northward excursion of tropical air that had been associated with a Pacific typhoon. The following three factors all had important influences on the collected chemical data sets: (1) local and distant stratospheric in puts into the upper and middle troposphere; (2) biomass-burning plumes from active fires in Alaska and Canada; (3) a band of 'low ozone' upper tropospheric air that was observed by airborne differential absorption lidar (DIAL) above the aircraft maximum altitude. Other modification factors observed on some flights included urban pollution from U.S. and Canadian cities, tropical air that had been associated with a Pacific typhoon, and precipitation scavenging by clouds and rain. Many flights were affected by several of the above factors

    As part of the ERESE program, three high school seniors aboard the ALIA expedition generated contents and published a live trip website with a wide range of information about the science and personal aspects of the cruise. These activities served to relate as much meaningful information about the month-long research cruise in the South Pacific as possible, to people of all ages and skills. The website http://earthref.org/ERESE/projects/ALIA/ has reports on almost every aspect of the research cruise; from what it is like staying on the Research Vessel Kilo Moana for a month, to operating machinery, to interviews with the captain and chief scientists, and even how the equipment aboard works, in less than technical terms. An effective way to relay what was actually going on aboard the Kilo Moana, were the daily reports, written by the high school students, complete with the pictures and videos taken that day. This website connected the ALIA cruise to high school students and classrooms, who were following the expedition through the website both in the United States and in Samoa. High school seniors designed and implemented the "CruiseWatch" feature on the Alia website. This "applet" extracts data from the shipboard datastream and relays them to the ERESE website at the San Diego Supercomputing center via satellite, where they are prepared for real-time display on the cruise website. Data displayed include the ships' location on the map, geographic coordinates, heading, speed and wind speed. During dredging operations it displays the length of wire deployed, wire speed and wire tension. Overall the website with the daily reports and photographs, in addition to other web media, gave this trip a unique ability to engage people from around the world in researching oceanographic and geological phenomena.

    From February 1986 to the present, the AOL participated in six interagency flight missions. (1) Shelf Edge Exchange Processes (SEEP II) (Department of Energy). The SEEP experiments are designed to assess the assimilative capacity of the Continental Shelf to absorb the energy by-products introduced into the near-shore ocean environment from coastal communities and marine activities such as energy production plants and offshore oil operations. (2) BIOWATT II (Office of Naval Research). The major objective of this study was to provide a better understanding of the relationships between ocean physics, biology, bioluminescence, and optics in oligotrophic portions of the Atlantic Ocean. (3) Fall Experiment (FLEX) (Department of Energy). The FLEX studies were designed to determine the fate of low salinity water in the coastal boundary zone that is advected south towards the Florida coast during autumn. (4) Greenland Sea and Icelandic Marine Biological Experiments (NASA). The investigations were designed to evaluate the distribution of surface layer chlorophyll in the Greeland Sea and in the coastal waters in the vicinity of Iceland. (5) Submerged Oceanic Scattering Layer Experiment (Naval Ocean Systems Center). This flight experiment demonstrated for the first time the feasibility of detecting and metrically measuring the depth to submerged layers of particulate matter in the shelf break region and in the inner coastal zone. (6) Microbial Exchanges and Coupling in Coastal Atlantic Systems (National Science Foundation). This investigation was designed to study the transportation and fate of particulates in coastal waters and in particular the Chesapeake Bay/coastal Atlantic Ocean. Shortly after the conduct of the flight experiments, airborne laser-induced chlorophyll a and phycoerythrin fluorescence data, as well as sea surface temperature and airborne expendable bathythermograph water column temperature profiles are supplied to cooperating institutions.

    Localized anthropogenic sources of atmospheric CH4 are highly uncertain and temporally variable. Airborne remote measurement is an effective method to detect and quantify these emissions. In a campaign context, the science yield can be dramatically increased by real-time retrievals that allow operators to coordinate multiple measurements of the most active areas. This can improve science outcomes for both single- and multiple-platform missions. We describe a case study of the NASA/ESA CO2 and Methane Experiment (COMEX) campaign in California during June and August/September 2014. COMEX was a multi-platform campaign to measure CH4 plumes released from anthropogenic sources including oil and gas infrastructure. We discuss principles for real-time spectral signature detection and measurement, and report performance on the NASA Next Generation Airborne Visible Infrared Spectrometer (AVIRIS-NG). AVIRIS-NG successfully detected CH4 plumes in real-time at Gb s-1 data rates, characterizing fugitive releases in concert with other in situ and remote instruments. The teams used these real-time CH4 detections to coordinate measurements across multiple platforms, including airborne in situ, airborne non-imaging remote sensing, and ground-based in situ instruments. To our knowledge this is the first reported use of real-time trace gas signature detection in an airborne science campaign, and presages many future applications.

    A large aperture scanning airborne lidar facility is being developed to provide important new capabilities for airborne lidar sensor systems. The proposed scanning mechanism allows for a large aperture telescope (25 in. diameter) in front of an elliptical flat (25 x 36 in.) turning mirror positioned at a 45 degree angle with respect to the telescope optical axis. The lidar scanning capability will provide opportunities for acquiring new data sets for atmospheric, earth resources, and oceans communities. This completed facility will also make available the opportunity to acquire simulated EOS lidar data on a near global basis. The design and construction of this unique scanning mechanism presents exciting technological challenges of maintaining the turning mirror optical flatness during scanning while exposed to extreme temperatures, ambient pressures, aircraft vibrations, etc.

    2016-04-01

    Drilling the carbonate platforms and drifts in the Maldives aimed to recover the marine tropical record of the Neogene sea-level changes and the onset of the monsoon related current system in the Indian Ocean. To reach this goal, eight sites were drilled along two transects in the Kardiva Channel in the Inner Sea of the Maldives during IODP Expedition 359. The recovered cores and log data retrieved the material to achieve all the objectives set for the expedition. The most arresting accomplishment is the documentation of how the sea level controlled the carbonate platform system that was thriving during the Miocene Climate Optimum abruptly transitioned into a current-dominated system in the late Middle Miocene. This transition is linked to the onset of an early intensification of the Indian monsoon and the coeval demise of some of the Maldivian platforms. Cores and downhole logs allowed producing a solid record and reconstructing the Neogene environmental changes in the central Indian Ocean. Preliminary shipboard analyses allow a precise dating of this major paleoclimatological and paleoceanographical changes, as it also applies for the extension of the Oxygen Minimum Zone (OMZ) into this part of the Indian Ocean. Coring produced a solid framework to foster the post-cruise research of these distinct topics. In addition, complete spliced sections and logging at key sites during Expedition 359 provide the potential to assemble a cycle-based astrochronology for the Neogene section in the Maldives. This high-resolution chronology will allow: 1) independent ages to be assigned to key biostratigraphic events in the Maldives for comparison with those from other tropical regions; 2) more precise ages for the major sequence boundaries and unconformities; and 3) evaluation of higher-resolution sedimentation rate variations.

    The Science in the Stratosphere program, first established in 1992, was conceived to introduce K-6 teachers to airborne infrared astronomy through the Kuiper Airborne Observatory (KAO), and to use this venue as a basis for seeing scientists at work in a mission-intensive program. The teachers selected for this program would bring their new perspectives back to their schools and students. Unlike the related FOSTER program, the emphasis of this program was on more intensive exposure of the KAO mission to a small number of teachers. The teachers in the Science in the Stratosphere program essentially lived with the project scientists and staff for almost a week. One related goal was to imbed the KAO project with perspectives of working teachers, thereby sensitizing the project staff and scientists to educational outreach efforts in general, which is an important goal of the NASA airborne astronomy program. A second related goal was to explore the ways in which K-5 educators could participate in airborne astronomy missions. Also unlike FOSTER, the Science in the Stratosphere program was intentionally relatively unstructured, in that the teacher participants were wholly embraced by the science team, and were encouraged to 'sniff out' the flavor of the whole facility by talking with people.

    Created in 2000 and supported by the EU Framework Programmes since then, EUFAR was born out of the necessity to create a central network and access point for the airborne research community in Europe. With the aim to support researchers by granting them access to research infrastructures, not accessible in their home countries, EUFAR also provides technical support and training in the field of airborne research for the environmental and geo-sciences. Today, EUFAR2 (2014-2018) coordinates and facilitates transnational access to 18 instrumented aircraft and 3 remote-sensing instruments through the 13 operators who are part of EUFAR's current 24-partner European consortium. In addition, the current project supports networking and research activities focused on providing an enabling environment for and promoting airborne research. The EUFAR2 activities cover three objectives, supported by the internet website www.eufar.net: (I - Institutional) improvement of the access to the research infrastructures and development of the future fleet according to the strategic advisory committee (SAC) recommendations; (ii - Innovation) improvement of the scientific knowledge and promotion of innovating instruments, processes and services for the emergence of new industrial technologies, with an identification of industrial needs by the SAC; (iii - Service) optimisation and harmonisation of the use of the research infrastructures through the development of the community of young researches in airborne science, of the standards and protocols and of the airborne central database. With the launch of a brand new website (www.eufar.net) in mid-November 2015, EUFAR aims to improve user experience on the website, which serves as a source of information and a hub where users are able to collaborate, learn, share expertise and best practices, and apply for transnational access, and education and training funded opportunities within the network.

    Stratospheric constant pressure analyses of geopotential height and temperature, produced as part of regular operations at the National Meteorological Center (NMC), were used by several participants of the Antarctic Ozone Expedition. A brief decription is given of the NMC stratospheric analyses and the data that are used to derive them. In addition, comparisons of the analysis values at the locations of radiosonde and aircraft data are presented to provide indications for assessing the representativeness of the NMC stratospheric analyses during the 1987 Antarctic winter-spring period.

    This paper describes afield program conducted by NOAA and the National Geographic Society in late August 1993 near Key West, Florida. The mission of the expedition was to obtain close-up photographic documentation of waterspouts. Using a NOAA helicopter as an observing platform, the participants dropped flares onto the sea surface to visualize the airflow and filmed waterspouts using a state-of-the art motion picture camera and still cameras. Over a dozen waterspouts funnel clouds wore observed, and the most detailed movies of spray vortices over taken were obtained.

    The mission of this activity, know as the Cooperative Program in Space Sciences (CPSS), is to conduct space science research and leading-edge instrumentation and technology development, enable research by the space sciences communities, and to expedite the effective dissemination of space science research, technology, data, and information to the educational community and the general public. To fulfill this mission, USRA recruits and maintains a staff of scientific researchers, operates a series of guest investigator facilities, organizes scientific meetings and workshops, and encourages various interactions with students and university faculty members.

  7. Airborne particulate matter in spacecraft

    NASA Technical Reports Server (NTRS)

    1988-01-01

    Acceptability limits and sampling and monitoring strategies for airborne particles in spacecraft were considered. Based on instances of eye and respiratory tract irritation reported by Shuttle flight crews, the following acceptability limits for airborne particles were recommended: for flights of 1 week or less duration (1 mg/cu m for particles less than 10 microns in aerodynamic diameter (AD) plus 1 mg/cu m for particles 10 to 100 microns in AD); and for flights greater than 1 week and up to 6 months in duration (0.2 mg/cu m for particles less than 10 microns in AD plus 0.2 mg/cu m for particles 10 to 100 microns in AD. These numerical limits were recommended to aid in spacecraft atmosphere design which should aim at particulate levels that are a low as reasonably achievable. Sampling of spacecraft atmospheres for particles should include size-fractionated samples of 0 to 10, 10 to 100, and greater than 100 micron particles for mass concentration measurement and elementary chemical analysis by nondestructive analysis techniques. Morphological and chemical analyses of single particles should also be made to aid in identifying airborne particulate sources. Air cleaning systems based on inertial collection principles and fine particle collection devices based on electrostatic precipitation and filtration should be considered for incorporation into spacecraft air circulation systems. It was also recommended that research be carried out in space in the areas of health effects and particle characterization.

    The NASA Student Airborne Research Program (SARP) is a unique summer internship program for advanced undergraduates and early graduate students majoring in the STEM disciplines. SARP participants acquire hands-on research experience in all aspects of an airborne research campaign, including flying onboard an major NASA resource used for studying Earth system processes. In summer 2012, thirty-two participants worked in four interdisciplinary teams to study surface, atmospheric, and oceanographic processes. Participants assisted in the operation of instruments onboard the NASA P-3B aircraft where they sampled and measured atmospheric gases and imaged land and water surfaces in multiple spectral bands. Along with airborne data collection, students participated in taking measurements at field sites. Mission faculty and research mentors helped to guide participants through instrument operation, sample analysis, and data reduction. Over the eight-week program, each student developed an individual research project from the data collected and delivered a conference-style final presentation on his/her results. We will discuss the results and effectiveness of the program from the first four summers and discuss plans for the future.

    Japanese Antarctic Research Expedition (JARE) commenced on the occasion of International Geophysical Year in 1957-1958. Syowa Station, the primary station for JARE operations, is located along the northeastern coastal region of Lützow-Holm Bay, East Antarctica (69° 00'S, 39° 35'E), and was opened on 29 January 1957. Since then, JARE have been carrying out research in various fields of earth and planetary sciences and life science. Astronomical science, however, has not been popular in Antarctica. In 1995, JARE established a new inland station, Dome Fuji Station (77° 19'S, 39° 42'E), which, at 3,810 m a.s.l., is located on one of major domes of the Antarctic ice sheet, some 1,000 km south of Syowa. The climatic conditions at Dome Fuji are harsh, with an annual average air temperature of -54°C, and a recorded minimum of -79°C. In 2007, JARE completed scientific drilling to obtain ice core samples of the Antarctic ice sheet reaching 3,050 m in depth. These ice cores record environmental conditions of the earth extending back some 720,000 B.P. In recent years, it is widely known that the high-altitude environment of inland Antarctica is suitable for astronomical observations and the Japanese astronomy community identified Dome Fuji Station as a potential candidate for a future astronomical observatory. In this article, the history of Japanese Antarctic activities are described in terms of access to the inland plateau of the Antarctic continent. The general scheme and future plans of science objectives and logistics of JARE will also be introduced.

    In March 2011, a Final Rule for expedited reporting of serious adverse events took effect in the United States for studies conducted under an Investigational New Drug (IND) application. In December 2012, the U.S. Food and Drug Administration (FDA) promulgated a final Guidance describing the operationalization of this Final Rule. The Rule and Guidance clarified that a clinical trial sponsor should have evidence suggesting causality before defining an unexpected serious adverse event as a suspected adverse reaction that would require expedited reporting to the FDA. The Rule's emphasis on the need for evidence suggestive of a causal relation should lead to fewer events being reported but, among those reported, a higher percentage actually being caused by the product being tested. This article reviews the practices that were common before the Final Rule was issued and the approach the New Rule specifies. It then discusses methods for operationalizing the Final Rule with particular focus on relevant statistical considerations. It concludes with a set of recommendations addressed to Sponsors and to the FDA in implementing the Final Rule. PMID:26550466

  11. Sharing Data: Building on the Traditions of Collaborative Ocean Expeditions

    Collaborative international marine research programs over the past 60 years have built on the historic tradition of extended national expeditions during the end of the 19th and beginning of the 20th centuries that explored new regions of the ocean and integrated knowledge: the Challenger, Albatross, and Meteor Expeditions. As oceanography matured after WWII, a new style of collaborative program emerged that focused on specific processes or problems rather than general exploration; the International Geophysical Year (IGY, 1957-58) was followed by the International Decade of Ocean Exploration (IDOE, 1970s). The latter set the stage for regular campaign-style oceanography focused on large-scale problems beyond the capability of individuals or small groups. These have become a staple of international oceanography and provide a framework around which oceanographers from around the world can contribute to global ocean discovery regardless of the capabilities of their individual nations. These collaborations have explored everything from processes controlling and associated with the formation of new ocean floor (RIDGE) to the Census of Marine Life. New collaborations have extended the concept of the international campaign to networks of autonomous vehicles (ARGO) in which all data are freely available. Regardless of the immediate discoveries associated with a campaign, much of its influence derives from the free availability of the data. Those research programs that have made digital data freely available have had an enormous follow-on impact as new models (digital and otherwise) are applied to the results. .

  12. Polar poisons: did Botulism doom the Franklin expedition?

    In 1845 the Franklin expedition left London with 2 ships and 134 men on board in an attempt to find the route through the Northwest Passage. The ships were built with state-of-the-art technology for their day, but provisioned with supplies from the lowest bidder. After taking on fresh provisions in the Whalefish Islands, off the coast of Greenland, the entire crew was never heard from again. Graves found on remote Beechey Island indicate that three able-bodied seamen died during the first winter. A note written on a ship's log, later found in a cairn, indicate that the expedition's leader, Sir John Franklin, died during the second winter entrapped on the ice, by which time 24 men had also perished. The remaining crew failed in their attempt to walk out of the Arctic by an overland route. In 1981 Owen Beattie, from the University of Alberta, exhumed the remains of the sailors from the three graves on Beechey Island. Elevated lead levels were found in all three sailors. While lead poisoning has been a leading theory of the cause of the crew's deaths, blamed on the crudely tinned provisions the ships carried with them from England, chronic lead exposure may only have weakened the crew, not necessarily killed them. One of three exhumed sailors also had in his intestine the spores of an unspecified Clostridium species. The theory put forth by this article is that Botulism, type E, which is endemic in the Arctic, may have been responsible for their deaths.

  13. Initiating Piloted Mars Expeditions with Medium-Lift Launch Systems

    NASA Astrophysics Data System (ADS)

    Bonin, G. R.

    A method of accomplishing manned expeditions to Mars with existing medium-lift launch systems is discussed. In this architecture, 20-tonne propulsion stages are placed individually in low-Earth orbit, where they are mated to Mars-bound payloads and ignited at successive perigees to execute trans-Mars injection. Spacecraft follow conjunction-class trajectories to the red planet and utilize aerobraking for orbital capture and descent. Return vehicles are fuelled with methane/oxygen bipropellant synthesized primarily from Martian resources. Dispatching expeditions from orbit with individual, high-energy stages - rather than directly from the Earth's surface - allows for the division of mission mass into more manageable components, which can be launched by vehicles that exist today. This plan does not require the development of heavy-lift launch technology: an effective yet costly proposition that may otherwise hinder current space exploration initiatives. Without the need for heavy-lift boosters, manned missions to Mars can be undertaken presently, and within the constraints of today's space exploration budgets. It is concluded that the mission design herein represents a less robust, though more economically viable method for initiating manned Mars exploration than proposals which require heavy-lift technology - an alternative method by which a new planet could be opened to humanity.

    The Environmental Research Aircraft and Sensor Technology (ERAST) program is a NASA initiative that seeks to demonstrate the application of cost-effective aircraft and sensor technology to private commercial ventures. In 1997-98, a series of flight-demonstrations and image acquisition efforts were conducted over the Hawaiian Islands using a remotely-piloted solar- powered platform (Pathfinder) and a fixed-wing piloted aircraft (Navajo) equipped with a Kodak DCS450 CIR (color infrared) digital camera. As an ERAST Science Team Member, I defined a set of flight lines over the largest coffee plantation in Hawaii: the Kauai Coffee Company's 4,000 acre Koloa Estate. Past studies have demonstrated the applications of airborne digital imaging to agricultural management. Few studies have examined the usefulness of high resolution airborne multispectral imagery with 10 cm pixel sizes. The Kodak digital camera integrated with ERAST's Airborne Real Time Imaging System (ARTIS) which generated multiband CCD images consisting of 6 x 106 pixel elements. At the designated flight altitude of 1,000 feet over the coffee plantation, pixel size was 10 cm. The study involved the analysis of imagery acquired on 5 March 1998 for the detection of anomalous reflectance values and for the definition of spectral signatures as indicators of tree vigor and treatment effectiveness (e.g., drip irrigation; fertilizer application).

    The National Ecological Observatory Network (NEON) is a planned facility of the National Science Foundation with the mission to enable understanding and forecasting of the impacts of climate change, land use change and invasive species on continental-scale ecology. Airborne remote sensing plays a critical role by providing measurements at the scale of individual shrubs and larger plants over hundreds of square kilometers. The NEON Airborne Observation Platform is designed to bridge scales from organism and stand scales, as captured by plot and tower observations, to the scale of satellite based remote sensing. Fused airborne spectroscopy and waveform LiDAR is used to quantify vegetation composition and structure. Panchromatic photography at better than 30 cm resolution will retrieve fine-scale information on land use, roads, impervious surfaces, and built structures. NEON will build three airborne systems to allow for regular coverage of NEON sites and the capacity to respond to investigator requests for specific projects. The system design achieves a balance between performance and development cost and risk, taking full advantage of existing commercial airborne LiDAR and camera components. To reduce risk during NEON construction, an imaging spectrometer design verification unit is being developed at the Jet Propulsion Laboratory to demonstrate that operational and performance requirements can be met. As part of this effort, NEON is also focusing on science algorithm development, computing hardware prototyping and early airborne test flights with similar technologies. This paper presents an overview of the development status of the NEON airborne instrumentation in the context of the NEON mission.
