    The AGU Council will meet on Sunday, 2 December 2012, at the InterContinental Hotel in San Francisco, Calif. The meeting, which is open to all AGU members, will include discussions of AGU's new Grand Challenge Project (a project that will be introduced to members at the 2012 Fall Meeting), the proposed AGU scientific ethics policy, publishing strategies, future plans for honors and recognition, and leadership transition as new members join the Council. This year the Council experimented with a new approach to conducting business. By holding virtual meetings throughout the year, Council members have been able to act in a more timely manner and provide input on important membership and science issues on the Board of Directors' agenda. The Council Leadership Team—an elected subset of the Council—also experimented with a new approach, meeting every month to keep moving projects forward. This approach has increased communication and improved effectiveness in Council decision making.

  5. AGU Panel meets on career topics

    NASA Astrophysics Data System (ADS)

    Hollister, Charles

    Graduate students and their career opportunities in ocean and earth sciences were the focus of the Education and Human Resources (E & HR) Committee meeting held at the 1982 AGU Fall Meeting in San Francisco. A standing committee of AGU, the E & HR committee is responsible for matters concerning education in earth, ocean, and planetary sciences from precollege through graduate programs, including career guidance, academic preparation, student recruitment, and manpower supply and demand.At the meeting a draft of the AGU-sponsored Careers in Oceanography booklet by committee chairman C. Hollister was thoroughly discussed and a new draft will emerge soon for final approval. The booklet is designed to complement the Careers in Geophysics booklet recently published by AGU; the booklets contain information about planning a career, job opportunities, educational requirements, and a synopsis of where the prospective student might apply.

  6. Keeping Pseudoscience Out of AGU Meetings

    NASA Astrophysics Data System (ADS)

    Craddock, Robert A.

    2005-06-01

    I found the editorial, ``Speaking Up For Science'' (Eos, 86,(24), 14 June 2005, p. 225) disturbing, but not for the reasons you intended. The Smithsonian made a mistake, but nowhere do you discuss its efforts to correct that. More troublesome to me as a member of AGU is the blatant hypocrisy contained in the editorial. How many posters or presentations have been made at AGU meetings in the last 10-20 years that support creationism, intelligent design, or other forms of pseudo-science, such as the so-called ``face'' on Mars?

  7. AGU Council to Meet in December

    NASA Astrophysics Data System (ADS)

    Enderlein, Cheryl L.

    2010-11-01

    The AGU Council will hold a meeting on Sunday, 12 December 2010, in San Francisco in conjunction with the Fall Meeting. This is the first meeting of the reconfigured Council, chaired by President­elect Carol Finn. As an outcome of the membership vote a year ago, the composition and the focus of the Council changed. With the creation of the Board of Directors to handle the business and fiduciary responsibilities of the organization, the Council is free to focus on science policy and other science-related matters. There are currently 59 Council members, including section presidents and presidents-elect, focus group chairs and vice chairs, committee chairs, early-career scientists, and the AGU president, president-elect, and executive director.

    McPhaden, Michael J.

    2010-10-01

    The engagement and enthusiasm of Board members and senior staff were evident as we met for the first Board of Directors meeting on 20-21 September 2010 at AGU headquarters, and much was accomplished over the 1.5 days. The meeting kicked off with a look to the future. Board members and staff had been asked to submit imagined headlines for 2019, the year that AGU will celebrate its 100th anniversary. This was a question raised by Executive Director Chris McEntee as she interacted with AGU leaders over the past several months. Board members and staff replied with a wide variety of headlines that inspired us to think about what is possible for AGU as we move forward as an organization. The headlines are posted on the AGU Web site (http://www.agu.org/about/presidents_msg/), and we encourage you to submit your own headline to agu_execdirector@agu.org.

  9. AGU Career Center attracts hundreds of Fall Meeting attendees

    Cooper, Paul

    2012-02-01

    The poster hall of the 2011 AGU Fall Meeting was the venue not only for scientific discussion and exchange of ideas—Fall Meeting attendees also explored new career opportunities and received career advice at AGU's Career Center. For many years, recruiters and hiring managers have found ideal candidates for open positions during the AGU Fall Meeting through the Career Center. Last year was no exception: Recruiters browsed resumés, visited posters, and attended talks to find talented individuals to interview during the week. In addition, hundreds of meeting attendees looking for a new job or a postdoc position visited the Career Center and checked the online AGU Career Center job board to request interviews. Career counselor Alaina Levine of Quantum Success Solutions gave private one-on-one career advice to 47 meeting attendees, making sure that each individual she counseled left the session with clearer career objectives and tactics to bring these objectives to fruition.

    Robichaux, Emily; Tomb, Jennifer

    2013-10-01

    AGU staff is dedicated to offering cutting-edge technology at Fall Meeting to improve meeting attendees' experience, provide state-of-the-art scientific content features, and continue developing features and elements of community building and social media. The overall goal is to implement technology that provides an accessible, manageable, and personal experience at Fall Meeting.

  12. Moving AGU Meetings sites [Comment to “Fall Meeting site”

    NASA Astrophysics Data System (ADS)

    Lanzerotti, L. J.; Maclennan, C. C.

    1984-04-01

    A recent letter to Eos by AGU member Dan Baker (March 13, 1984, p. 98) suggested that a method of reducing the attendance at the Fall AGU meeting would be to move it from San Francisco to his namesake, namely Bakersfield. He cited as a precedent the probably reduced attendance at the (at that time) upcoming Spring Meeting to be held in Cincinnati. While neither of us is promoting cities with names similar to ours, nevertheless we both believe that the recent meeting held in Cincinnati was a great success, even with the reduced number of registrants. The arrangements in the Convention Center, as well as the proximity of the hotels to the convention center and the amenities in the hotels were all excellent, and easily matched or surpassed the facilities in any of the cities in which the major meetings have been held to this time. Furthermore, we would like to make a qualitative judgment that the number of attendees at the individual sessions were perhaps as large as in a Baltimore or Washington meeting. In those meetings the number of registrants may have been larger, but the number of attendees at the given session may have been smaller; a significant proportion of the attendees at any given time would likely be visiting the offices of their contract monitors. Admittedly, the Spring Meeting has been an ideal opportunity to both attend scientific sessions and to lobby for additional research support. However, such lobbying does not necessarily make for increased attendance at the scientific sessions.

  13. AGU Fall Meeting Mentors for Students Sought

    NASA Astrophysics Data System (ADS)

    Karsten, Jill

    2005-11-01

    Science mentors are sought for the Minorities Striving and Pursuing Higher Degrees of Success in Earth System Science Initiative (MS PHD's) Professional Development Program. MS PHD's, begun in 2004, is a joint NASA-U.S. National Science Foundation funded program that provides early career mentoring, professional development, and networking for minority undergraduate and graduate students pursuing degrees in the Earth and space sciences. AGU is one of several major sponsoring societies for this five-year effort to provide participating students with increased exposure to, interaction with, and engagement in the Earth system science community, in order to help them achieve their academic and professional goals.

    NASA Astrophysics Data System (ADS)

    Holm Adamec, Bethany

    2012-10-01

    AGU is committed to fostering the next generation of Earth and space scientists. We work on this commitment in many ways, one of which is partnering with the National Earth Science Teacher's Association (NESTA) to hold the annual Geophysical Information for Teachers (GIFT) workshop at the Fall Meeting. GIFT allows K-12 science educators (both classroom and informal) to hear from scientists about their latest Earth and space science research, explore new classroom resources for engaging students, and visit exhibits and technical sessions during the Fall Meeting. Six teams of leading scientists and education/public outreach professionals will give talks and lead teachers through interactive classroom activities over the course of 2 days at GIFT 2012. Becoming a GIFT presenter is a highly competitive process, with 29 applications evaluated through a peer review system this year. Science standards, prior classroom testing of materials, expertise of presenters, teacher interests, and AGU's science priorities are all taken into account during the selection process.

  16. AGU Cinema: Festival of short science films at Fall Meeting

    Harned, Douglas A.

    2012-11-01

    New technologies have revolutionized the use of video as a means of science communication and have made it easier to create, distribute, and view. With video having become omnipresent in our culture, it sometime supplements or even replaces writing in many science and education applications. An inaugural science film festival sponsored by AGU at the 2012 Fall Meeting in San Francisco, Calif., in December will showcase short videos—30 minutes or less in length—developed to disseminate scientific results to various audiences and to enhance learning in the classroom. AGU Cinema will feature professionally produced, big budget films alongside low-budget videos aimed at niche audiences and made by amateurs. The latter category includes videos made by governmental agency scientists, educators, communications specialists within scientific organizations, and Fall Meeting oral and poster presenters.

  17. CO2 Emissions Generated by a Fall AGU Meeting

    NASA Astrophysics Data System (ADS)

    osborn, G.; Malowany, K. S.; Samolczyk, M. A.

    2011-12-01

    The process of reporting on and discussing geophysical phenomena, including emissions of greenhouse gases, generates more greenhouse gases. At the 2010 fall meeting of the AGU, 19,175 delegates from 81 countries, including, for example, Eritrea, Nepal, and Tanzania, traveled a total of 156,000,000 km to congregate in San Francisco for five days. With data on home bases of participants provided by AGU, we estimated the CO2 emissions generated by travel and hotel stays of those participants. The majority of the emissions from the meeting resulted from air travel . In order to estimate the footprint of such travel, (a) distances from the largest airport in each country and American state (except Canada and California) to San Francisco were tabulated , (b) basic distances were converted to emissions using the TerraPass (TRX Travel Analytics) carbon calculator, (c) it was assumed that half the California participants would fly and half would drive, (d) it was assumed that half of Canadians would fly out of Toronto and half out of Vancouver, and (e) a fudge factor of 10% was added to air travel emissions to account for connecting flights made by some participants to the main airports in the respective countries (connecting flights are disproportionately significant because of high output during takeoff acceleration). Driving impacts were estimated with a Transport Direct/RAC Motoring Services calculator using a 2006 Toyota Corolla as a standard car. An average driving distance of 50 km to the departure airport, and from the airport upon return, was assumed. Train impacts were estimated using the assumption that all flying participants would take BART from SFO. Accomodation impacts were estimated using an Environmental Protection Agency calculator, an assumed average stay of 3 nights, and the assumption that 500 participants commuted from local residences or stayed with friends. The above assumptions lead to an estimate, which we consider conservative, of 19 million kg of

    Uhlenbrock, Kristan

    2011-10-01

    This year marks the fourth annual Geosciences Congressional Visits Day (Geo-CVD), in which scientists from across the nation join together in Washington, D. C., to meet with their legislators to discuss the importance of funding for Earth and space sciences. AGU partnered with seven other Earth and space science organizations to bring more than 50 scientists, representing 23 states, for 2 days of training and congressional visits on 20-21 September 2011. As budget negotiations envelop Congress, which must find ways to agree on fiscal year (FY) 2012 budgets and reduce the deficit by $1.5 trillion over the next 10 years, Geo-CVD scientists seized the occasion to emphasize the importance of federally funded scientific research as well as science, technology, engineering, and math (STEM) education. Cuts to basic research and STEM education could adversely affect innovation, stifle future economic growth and competitiveness, and jeopardize national security.

(See also the About AGU article by Peter Gleick and Randy Townsend on p. 433.) At this event, members of the Task Force on Scientific Ethics will discuss current efforts to update the Union's policies on scientific integrity. In addition, AGU members will have the opportunity to become involved in helping to shape the future of AGU by providing feedback, ideas, and insights.

  20. Access to the Heads and Chairs Program expands beyond AGU Fall Meeting

    NASA Astrophysics Data System (ADS)

    Asher, Pranoti M.; Keane, Christopher M.

    2012-09-01

    The AGU Education and Public Outreach department is pleased to announce a new collaboration with the American Geosciences Institute (AGI) for AGU's existing Heads and Chairs Program. This collaboration developed from a mutual interest in supporting the higher education departments of Earth and space sciences, as well as a desire to combine activities and resources toward strengthening that support. Through this partnership, AGI's Workforce Program and AGU's education staff are hosting hour-long webinars on various topics each month to engage department heads and chairs in discussions that will help them share, learn, and apply new ideas to their own programs. The ultimate goal is to provide opportunities for open dialogue beyond the annual Heads and Chairs workshops held at the AGU Fall Meeting each year, as well as to support those heads and chairs who are unable to attend Fall Meeting.

  1. News media and new media: Strong coverage of AGU Fall Meeting

    2011-05-01

    As scientists at AGU's 2010 Fall Meeting engaged one another with talks, posters, and hallway chats last December, a steady stream of reporting and commentary about all things Fall Meeting spilled out from the Moscone Center in San Francisco, Calif., to audiences throughout the world. Some 150 journalists—representing print, online, and broadcast media outlets, plus freelancers—reported from the meeting. Other reporters not present at the meeting participated in press conferences and other press events via live webcasts. Writers for nearly 2 dozen Earth and space science blogs churned out Fall Meeting-related blog postings. Twitter users also busily commented from the meeting, generating more than 4500 tweets labeled with the meeting's #AGU10 hashtag (a Twitter identity code). The outpouring of meeting-related news and commentary added up to more than 3000 stories, of which many reached far-flung parts of the globe, according to an analysis made using Vocus, a media monitoring service.

  4. Middle and high school students present posters at AGU Fall Meeting

    NASA Astrophysics Data System (ADS)

    Saltzman, Jennifer

    2011-06-01

    While science fairs may be one way for students to learn about science, AGU takes the science fair one step further by hosting middle and high school students from the San Francisco Bay Area so they can show off their research in the professional arena. The Bright Students Training as Research Scientists (Bright STaRS) program creates a special day at the AGU Fall Meeting for budding scientists. In addition to learning the ins and outs of geoscience research by participating in data collection and analysis for their research projects, they learn the importance of communication by presenting their results. Since 2004 the AGU Bright STaRS initiative has hosted students who have worked on research projects at universities, high schools, and science learning centers. The program enables them to spend a day at the Fall Meeting and to present their research in a poster session. Each year 10-15 abstracts are submitted by about 25-40 middle and high school students for this event; in 2010 this increased to 26 abstracts and 50 students. Since its inception, more than 250 students have participated in Bright STaRS.

  5. Ocean Sciences Best Student Papers for 1988 Joint AGU/ASLO Meeting

His thesis is on “The Role of Marine Fungi in Food Selection and Nutrition of the Salt Marsh Periwinkle Littorina irrorata Say (Gastropoda).” He received his B.A. in biology from the University of California, Santa Cruz.

  6. AGU Committee Update: Recent activities of NG Technical Committee

    NASA Astrophysics Data System (ADS)

    Rundle, John B.

    Beginning this year, the AGU has adopted a series of new policies designed to highlight the interdisciplinary aspects of the Union. As part of these new policies, members will soon be able to affiliate with the AGU Technical Committees, including the Nonlinear Geophysics (NG) Committee. In addition, the Technical Committees are now able to sponsor or co-sponsor technical sessions at both the Spring and Fall annual meetings, as well as make awards for best research and papers, and sponsor nominations for AGU Fellows and Union-wide awards.A website for the NG committee, with descriptions of the committee's activities and other functions, can be found via a link from the main AGU website, which is maintained by Jon Pelletier (University of Arizona). An AGU/NG listserver is maintained by the AGU staff liaison to NG, Dan Moore (DMoore@agu.org). AGU members wishing to be apprised of NG committee activities by inclusion in the listserv should either sign up through the NG web site, or send email to Dan Moore. As described, the NG committee can nominate an AGU member for election to AGU Fellow status. Don Turcotte (Cornell University) chairs the NG subcommittee on Fellow nominations.

The committee meets to review the forwarded nominations and decides who will be elected for the year.

  14. Extend your commitment to AGU

    NASA Astrophysics Data System (ADS)

    Voluntary contributions are essential for AGU to maintain and enhance its many innovative programs. In addition to unrestricted contributions to AGU, up to half of your Supporting Member contribution may be designated to one or more of the special funds. One such group of funds are the Section Funds. The Section Funds were established by the Council to support special Section activities. The Hydrology Section has used some of its funds to tape Langbein Lectures given by Wilfried Brutsaert, Shlomo Neuman,and Mark Meier, and to produce videotape interviews with John Philip, Terrence O'Donnell, James C. I. Dooge, David Dawdy Mark Meier, Gilbert White, Stanley Davis, and Peter Eagleson. Other Sections have used their funds to subsidize tickets for the Best Student Paper awardees to attend the Section luncheon at the Fall and Spring Meetings, give partial travel support to other Bowie lecturers, and give partial travel support to luncheon speakers. More information is available online at http://www.agu.org/inside/supportmember_top.html.

  15. AGU on hydrological science

    NASA Astrophysics Data System (ADS)

    Hydrologists and other scientists expressed concern that progress in hydrology is impeded by a lack of programmatic focus within the National Science Foundation. In response to the concern, AGU president Don Anderson appointed a panel to assess the situation and to recommend an appropriate AGU position on this issue. The report of the panel was considered at the Fall meeting of the Council and approved as the formal Union position. Subsequently, it was transmitted to Robert Corell, head of the NSF Geosciences Directorate, for consideration. The position itself is given below.Hydrologic Science Within the NSF—A Position Statement: AGU recommends that NSF take steps to establish a unified program in hydrologic science that is commensurate with the importance of water in Earth processes at all scales.

  16. Section concerns addressed at Spring Meeting

    NASA Astrophysics Data System (ADS)

    Bales, Roger C.

    To keep abreast of current issues and plan future activities, Hydrology Section President Steve Burges brought a full agenda to the Executive Committee meeting held in Baltimore last May. The following highlights of that meeting are offered to keep you informed about what's new in the Hydrology Section.To communicate scientific results more effectively to the press at the Fall and Spring Meetings, section Press Officer Harry Lins is organizing a media-interest session that can highlight both science and policy aspects of a subject. Such a session will also help communicate scientific results to a more general audience. Special session convenors are also encouraged to open their session with a 5-10-minute introduction that highlights important issues to be presented in subsequent papers. These introductions are intended mainly for press representatives and nonspecialists in the audience. In general, the press is not well versed on water issues, and there is often less press interest in hydrology than in other areas of geophysics.

    In recent years, science has become inextricably linked to the political process. As such, it is more important now than ever for science to forge a better relationship with politics, for the health of both science and society. To help meet this need, the American Geophysical Union (AGU) strives to engage its members, shape policy, and inform society about the excitement of Earth and space science and its role in developing solutions for the sustainability of the planet. In the spring of 2012, AGU held its inaugural Science Policy Conference in Washington, D.C. The goal of this new conference is to ensure diverse discussions and viewpoints on the challenges and opportunities of Earth and space science policy. The meeting brought together more than 300 scientists, policymakers, industry professionals, members of the press, and other stakeholders to discuss Arctic, oceans, natural resources, and natural hazards science as they relate to challenges impacting society. Sessions such as Hydraulic Fracturing, Mitigation and Resiliency to Severe Weather, Governance and Security in the Arctic, and Ocean Acidification are examples of some of the intriguing science policy issues addressed at the conference. The AGU Science Policy Conference will be an annual spring event in Washington, D.C.

    The AGU Board of Directors held its first board meeting on 20-21 September 2010 in Washington, D. C. The meeting, chaired by President Michael McPhaden, marked another step forward in implementing AGU's new governance structure and strategic direction. The agenda included ongoing organizational business, high-level strategic discussions, and opportunities for Board development. In the new governance structure, the Board is responsible for governing the business aspects of AGU, while the Council is responsible for governing scientific affairs. The strategic plan guides both governing groups, staff, and other membership groups by providing clear goals and objectives. Of the 28 objectives in the AGU strategic plan, the volunteer and staff leadership identified eight as priorities. The priority objectives are listed in the diagram to the right, which is also posted on the AGU Web site.

    NASA Astrophysics Data System (ADS)

    Folger, Peter

    During this year's AGU Spring Meeting in Boston, held May 25-29, the AGU Council reaffirmed its opposition to the teaching of creationism as a scientific theory. By unanimous vote, the Council agreed with a recommendation from AGU's Committee on Public Affairs (COPA) to renew the statement that was first adopted in December 1981. The reaffirmed statement is as follows:"The Council of the American Geophysical Union notes with concern the continuing efforts by creationists for administrative, legislative, and juridical actions designed to require or promote the teaching of creationism as a scientific theory. "The American Geophysical Union is opposed to all efforts to require or promote the teaching of creationism or any other religious tenets as science.

    The 2008-2010 AGU Council adopted a strategic plan and voted to create a task force to facilitate AGU leadership in Earth and space sciences at its meeting on 7 June 2010. The meeting, at AGU headquarters in Washington, D. C., was the first part of a 4-day historic leadership conference that included 66 volunteer leaders and key staff as AGU prepares to transition to a new governance structure. The new Union officers (president, president-elect, general secretary, and international secretary), the newly established Board of Directors, and the new Council—which will consist of section presidents and presidents-elect, focus group chairs and vice chairs, committee chairs, and four appointed student/early-career scientists—take office on 1 July 2010.

  5. AGU Legislative Guide available

    NASA Astrophysics Data System (ADS)

    Richman, Barbara T.

    A guide to help AGU members communicate with legislators and government agency officials is available free of charge from AGU headquarters. The guide is based on the premise that input from the scientific community assists government to make decisions based on the latest factual information available.AGU's Guide to Legislative Information and Contacts was developed by AGU's Committee on Public Affairs and is based largely on a publication of the American Institute of Biological Sciences. The guide briefly outlines the key steps in the legislative process and lists sources of information on legislation. The booklet also provides guidelines for corresponding with legislators a n d for providing scientific testimony to Congress. It also delineates some o f the constraints under which AGU must operate when undertaking legislative activities.

  6. Is AGU in your will?

    NASA Astrophysics Data System (ADS)

    Consider whether or not you may wish to make a bequest to AGU in order that it may meet more adequately its growing responsibilities and opportunities. A bequest may be as simple or as complex as a donor's situation may require. And, regardless of whether a bequest is a small percentage of one's estate, a fixed amount of money, specified securities or other property, or the proceeds of a life insurance policy, it is likely to have tax advantages and will not deny you the continued use of your resources during your lifetime.On matters of this kind, you should consult your attorney. You should also feel free to bring your questions to Fred Spilhaus at AGU headquarters.

  13. Why AGU is important in Eastern Europe and should increase its role even more?

    NASA Astrophysics Data System (ADS)

    Mocanu, V.

    2007-12-01

    After the fall of the ex-communist system about twenty years ago, the East European countries faced a significant, multilateral challenge in all aspects of their economical, financial, military, scientific and especially educational and professional life. They had a pretty robust tradition in classic education and research, but had to prepare their young generation and specialists for a hard competition for grad-, post grad- and professional level competing with colleagues from other parts of the world. They had to restructure their systems and re-discovered the professional societies. AGU represented a certain model of efficiency on handling various aspects of geoscientific activities: integration of geophysics with other related disciplines like atmospheric sciences, hydrology and hydrogeology, volcanism, geochemistry etc., from deep Earth to the intergalactic space. Close cooperation with other boundary sciences, regular and very well organized meetings dedicated more to Solid earth (AGU Fall Meeting) or Near-Surface Geophysics (AGU Spring Meetings), its very close cooperation with the sister societies from Europe, other North, Central and South American countries as well as the Far East and Australia, permanent opening towards a strong international cooperation with all countries and societies world- wide, very active interest in education and career orientation, strong publication policy represented a certain attraction and a very tempting model for the East European countries. Their very quick development has to be joined by transformation of their higher education and research system in such a way that they become more and more competitive with other countries worldwide. They have to develop their own system so that it attracts more and more youngsters to remain/return home and contribute to the advance of their home countries and, in close partnerships with other developed and developing countries, with the guidance of the professional societies like AGU

  14. A Bit of History: The EGS, AGU, and EUG

    NASA Astrophysics Data System (ADS)

    1969-Waldo Smith (AGU Executive Director, 1944-1970) is invited to present an overview of the structure and function of AGU at a meeting convened by Keith Runcorn to discuss a proposal to form a European Geophysical Union (EGU). The EGU, as described in the notes of the meeting, is proposed ``principally in order to give more opportunity than presently exists, for young scientist in Europe to present their ideas and to benefit from interchanges with the scientists in the whole spectrum of disciplines embracing Earth and Planetary Sciences.'' 1971-The president of AGU, Homer Newell, and the new executive director, Fred Spilhaus, are invited by Runcorn to attend the Earth and Planetary Physics Colloquium and are asked to bring along the statutes and bylaws of AGU as an example to help in drafting the basis for the new European organization. The foundation is laid at that time for ongoing cooperation between AGU and what was soon to become EGS.

  1. Building a bridge between AGU and SEG

    NASA Astrophysics Data System (ADS)

    Pellerin, Louise; Bradford, John H.

    2012-05-01

    AGU and the Society of Exploration Geophysicists (SEG) complement each other in many ways. SEG is known for strength in applied geophysics and method development, while AGU is known for application of geophysics to broader scientific questions in Earth and atmospheric sciences. These boundaries are of course gray, and there is substantial and complementary overlap of interests, particularly among some disciplines; these include the study of passive and active source seismology, gravity and magnetic anomalies, and electrical and electromagnetic methodologies, as well as interest in the application of these methods to crustal structure, near- surface geophysics, geothermal exploration, and basin analysis. Facilitating communication between members of SEG and those of AGU has a significant impact on the geophysical sciences. The AGU-SEG Collaboration Committee (ASCC) was established as part of the AGUSEG Alliance Agreement, signed in 2010. In the agreement, ASCC was "charged with considering and making recommendations to the respective organizations regarding other areas of cooperation, such as joint workshops or programs and continuing- education courses." The first committee-wide meeting was held on 11 February 2011. Subsequent meetings are scheduled every 4-6 weeks.

  2. Why publish with AGU?

    NASA Astrophysics Data System (ADS)

    Graedel, T. E.

    The most visible activity of the American Geophysical Union is its publication of scientific journals. There are eight of these: Journal of Geophysical Research—Space Physics (JGR I), Journal of Geophysical Research—Solid Earth (JGR II), Journal of Geophysical Research—Oceans and Atmospheres (JGR III), Radio Science (RS), Water Resources Research (WRR), Geophysical Research Letters (GRL), Reviews of Geophysics and Space Physics (RGSP), and the newest, Tectonics.AGU's journals have established solid reputations for scientific excellence over the years. Reputation is not sufficient to sustain a high quality journal, however, since other factors enter into an author's decision on where to publish his or her work. In this article the characteristics of AGU's journals are compared with those of its competitors, with the aim of furnishing guidance to prospective authors and a better understanding of the value of the products to purchasers.

  3. AGU hydrology publication outlets

    NASA Astrophysics Data System (ADS)

    Freeze, R. Allan

    In recent months I have been approached on several occasions by members of the hydrology community who asked me which of the various AGU journals and publishing outlets would be most suitable for a particular paper or article that they have prepared.Water Resources Research (WRR) is the primary AGU outlet for research papers in hydrology. It is an interdisciplinary journal that integrates research in the social and natural sciences of water. The editors of WRR invite original contributions in the physical, chemical and biological sciences and also in the social and policy sciences, including economics, systems analysis, sociology, and law. The editor for the physical sciences side of the journal is Donald R. Nielson, LAWR Veihmeyer Hall, University of California Davis, Davis, CA 95616. The editor for the policy sciences side of the journal is Ronald G. Cummings, Department of Economics, University of New Mexico, Albuquerque, NM 87131

  7. What's a Nice Hummingbird Like You Doing at an AGU Meeting Like This? (or, Operation RubyThroat Meets The GLOBE Program)

    NASA Astrophysics Data System (ADS)

    Hilton, B.

    2003-12-01

    "Operation RubyThroat: The Hummingbird Project" is an international cross-disciplinary initiative that uses Ruby-throated Hummingbirds (Archilochus colubris) as a hook to excite K-12 students (and adults) about science learning. In 2002, Operation RubyThroat affiliated with The GLOBE Program as the first GLOBE protocol that involves animal behavior. Through Operation RubyThroat, students make observations about hummingbird phenology, behavior, and ecology and correlate their data against traditional GLOBE observations of atmosphere, climate, land cover, soils, hydrology, and phenology. Although Ruby-throated Hummingbirds (RTHUs) breed throughout the eastern half of the United States and southern Canada and may be the most common and most widely distributed of all 338 hummingbird species, little is known about how abiotic environmental factors affect their migration, nesting activities, and everyday behavior. Operation RubyThroat participants in the U.S. and Canada log early arrival dates of RTHUs during spring migration, note their presence throughout the breeding season, and report the last date RTHUs are seen in autumn. Conversely, participants in Mexico and all seven Central American countries (the region in which RTHUs spend their non-breeding months) watch for early arrivals in fall and late departures in spring. Participants also attempt to estimate numbers of RTHUs in local populations by counting the number of visits hummingbirds make to feeders and/or flowers in a 45-minute time block. Optional activities include observations of RTHU nesting behaviors and determining RTHU preferences for various species of native and exotic nectar sources. Participating schools are encouraged to establish Schoolyard Hummingbird Habitats in which to make their observations, but data may be collected in backyards or at local parks, nature centers, botanical gardens, and other sites where RTHUs occur. Adults not affiliated with K-12 schools are invited to become certified in

    McPhaden, Michael J.

    2010-08-01

    On 1 July 2010, the first AGU Board of Directors took office. The board is composed of the president, president-elect, immediate past president, general secretary, international secretary, development board chair, six members elected by the Union membership, vice chair of the AGU Council, and the executive director. Two additional members may be nominated by the AGU president and approved by the board. The creation of the board is a result of the new governance structure approved by the AGU membership in November 2009. The board is responsible for the business aspects of the Union, while an expanded AGU Council will focus on science issues. Council members will be introduced in a future issue of Eos.

  13. Advocacy and AGU

    NASA Astrophysics Data System (ADS)

    In May 1982, the AGU Council approved the following policy on the Union's role in advocacy on public issues.The American Geophysical Union is an association of scientists, scholars, and interested lay public for the purpose of advancing geophysical science. The Union shares a collateral sense of responsibility to assure that the results of geophysical research are made available to benefit all mankind. The Union encourages its members to exercise their individual sense of responsibility in addressing political and social issues. Should they choose to act collectively on such issues, other organizations exist for such purposes. The American Geophysical Union, as a society, should preserve its unique position as an objective source of analysis and commentary for the full spectrum of geophysical science. Accordingly, the following policies should guide the American Geophysical Union's role as an advocate:

  14. New Format for AGU Print Journals

    NASA Astrophysics Data System (ADS)

    Cook, Bill

    2010-08-01

    AGU has adopted a new print format for Journal of Geophysical Research, Water Resources Research, Geophysical Research Letters, and Reviews of Geophysics starting with the July 2010 issues. In the new format, pages are condensed and rotated so that two pages of journal text fit side by side on one printed page. Why has AGU chosen to go this route? The rising costs of print, the decline of print subscriptions, and the need to conserve resources used in printing have led us to consider many options in delivering our journals to our customers. The most effective version, of course, is the electronic version, but many customers still require print copies for various purposes. As long as there is a demand for print, we will attempt to meet that demand and to explore all possibilities for reducing the costs of the format.

  15. Tomorrow's AGU: Building a Foundation for Good Governance

    NASA Astrophysics Data System (ADS)

    Grove, Timothy L.

    2009-09-01

    In May, the AGU Council voted unanimously to create a 16-member board of directors to oversee the business of the Union, and to expand the Council beyond section leadership to include focus group and committee leaders concentrating on matters of science and related Union activities such as AGU publications, meetings, and awards and honors (see Eos, 90(25), 213, 23 June 2009). This fall, the AGU membership will be asked to vote on these important changes. The Council action followed careful deliberation and reflects the recommendations of the Future Focus Task Force, which was formed to answer the question, “How will AGU need to change the way it does business to achieve its strategic vision and mission and remain a preeminent scientific society?”

    DeVito, M. Catherine

    1992-03-01

    On March 4 at AGU headquarters, the Real Estate Committee reviewed plans for the construction of a new headquarters building, which is to be completed in early 1994 on the current 2000 Florida Avenue site. The committee discussed in detail the project's budget, scheduling, and design. This meeting marks the completion of the design and development phase. The project's architect, Shalom Baranes, will now begin construction drawings.Several years ago, projections of the Union's growth showed that by about 1995, the current building would be insufficient to house the staff required to serve the Union. A study was undertaken by a special committee with the help of consultants. This “Real Estate Committee,” chaired by Ned A. Ostenso, explored the advantages and disadvantages of six expansion options: to sell the current building and lease; to sell the current building and buy another; to “do nothing” to the existing building and expand by leasing; to keep the existing building and build a new, independent addition; to renovate the existing building and add a new addition; or to construct a new building at the current site.

    In continuation of our work to strengthen alliances with key organizations in the Earth and space science community, AGU president Michael McPhaden, president-elect Carol Finn, and I held a series of meetings with leaders from other science societies during the 2011 Fall Meeting. Over the course of 2 days we met with leaders from the Geophysical Society of America, European Geosciences Union, Japan Geosciences Union, Ethiopian Geophysical Union, Asia Oceania Geosciences Society, Chinese Geophysical Society, and Asociación Latinoamericana de Geofísica Espacial. This gave us a valued opportunity to discuss the common interests and challenges we all face and to learn from each other's experience. The meetings allowed AGU to strengthen existing cooperative agreements and reach new levels of understanding between us and other societies. Additionally, we met with representatives from the Korean Ocean Research and Development Institute to discuss their intention to establish a geophysical union modeled after AGU.

  3. Is AGU in your will?

    NASA Astrophysics Data System (ADS)

    Whitten, Charles A.

    We are approaching the time of year when the IRS requires that we review our ‘financial position.’ The new tax laws, we are told, have benefits for everyone. These ‘goodies’ may be hard to find. However, those laws that apply to estates have been changed significantly, and our lawyer urges that my wife and I update our wills.We hope you read the AGU-GIFT editorial on deferred giving in the September 15, 1981, Eos. John Reed mentioned different options. The Steering Committee for AGU-GIFT believes that the designation of a bequest to AGU in an updated will may be appealing to some of AGU's senior members who are well established, whose career-long commitments are largely fulfilled, and who may be better shielded from inflation than some other members.

AGU recognizes the importance of having a diverse pool of new researchers who can enrich Earth and space sciences with their skills and innovation. That's why one of our four strategic goals is to help build the global talent pool and provide early-career scientists with networking opportunities like this one.

  9. Proposed change in the AGU Bylaws

    NASA Astrophysics Data System (ADS)

    At its meeting on May 19, 1987, the AGU Council gave initial approval to an amendment to Bylaw 14, relating to election procedures, to clarify these procedures and bring them into conformity with Robert's Rules of Order. The changes are as follows: Add a new Article 14d to read: “Elections shall be accomplished by mail.”Add Article 14e to read: “If more than two candidates are nominated, voters shall be required to rank candidates in order of their preference. In tallying such votes, if no candidate has a majority of the first-place votes, then the candidate with the fewest first-place votes will be eliminated and the second-place votes on those ballots distributed among the other candidates and this process repeated until one candidate has a clear majority.”Change to Article 14f the old 14d, which reads: “Results of the general election shall be announced at the Annual Business Meeting.”Notice of this proposed change is given in accordance with Article 126 of the Statutes, which requires that proposed amendments to the Bylaws be published in an AGU publication of general circulation no less than 30 days prior to a second consideration by the Council. The Council will consider this proposal for final passage at its December 1987 meeting in San Francisco, Calif.

    AGU will present its inaugural Science Policy Conference, 30 April to 3 May 2012, at the Ronald Reagan Building and International Trade Center, located in downtown Washington, D. C. This conference will bring together leading scientists, policy makers, industry professionals, press, and other stakeholders to discuss natural hazards, natural resources, oceans, and Arctic science and the role these sciences play in serving communities. To bridge the science and policy fields, AGU plans to host this conference every 2 years and focus on the applications of Earth and space sciences to serve local and national communities. "Our nation faces a myriad of challenges such as the sustainability of our natural resources, current and future energy needs, and the ability to mitigate and adapt to natural and manmade hazards," said Michael McPhaden, president of AGU. "It is essential that policies to address these challenges be built on a solid foundation of credible scientific knowledge."

    Bates, J. J.

    2015-12-01

    In September 2014, the AGU Board of Directors approved two initiatives to help the Earth and space sciences community address the growing challenges accompanying the increasing size and complexity of data. These initiatives are: 1) Data Science Credentialing: development of a continuing education and professional certification program to help scientists in their careers and to meet growing responsibilities and requirements around data science; and 2) Data Management Maturity (DMM) Model: development and implementation of a data management maturity model to assess process maturity against best practices, and to identify opportunities in organizational data management processes. Each of these has been organized within AGU as an Editorial Board and both Boards have held kick off meetings. The DMM model Editorial Board will recommend strategies for adapting and deploying a DMM model to the Earth and space sciences create guidance documents to assist in its implementation, and provide input on a pilot appraisal process. This presentation will provide an overview of progress to date in the DMM model Editorial Board and plans for work to be done over the upcoming year.

  13. Entering a New ERA: Education Resources and AGU

    NASA Astrophysics Data System (ADS)

    2001-12-01

    Professional societies play a unique role in the on-going battle to improve public education in the Earth and space sciences. With guidance from its Committee on Education and Human Resources (CEHR), AGU has traditionally sponsored strong programs that provide mechanisms for linking its research membership with the formal/informal science education communities. Among the most successful of these are tutorials for K-12 teachers taught by AGU members during national meetings (e.g., GIFT - Geophysical Information For Teachers) and internships that allow teachers to experience geophysical science research first-hand (e.g., STaRS - Science Teacher and Research Scientist). AGU also co-sponsors major symposia to discuss and develop strategies for Earth science education reform (e.g., the NSF-sponsored Shaping the Future workshop) and provides an annual forum for the Heads and Chairs of undergraduate geoscience departments to discuss common problems and share solutions. In the fall of 2001, AGU expects to unveil a major new education and outreach website that will provide enhanced opportunities for communicating to students, teachers and the public about AGU members' research and new directions in geophysical science education. The most important contribution that AGU makes, however, is to validate and prominently endorse the education and outreach efforts of its members, both by sponsoring well-attended, education-related special sessions at AGU national meetings and by annually honoring individuals or groups with the Excellence in Geoscience Education award. Recent staff changes at AGU headquarters have brought new opportunities to expand upon these successful existing programs and move in other directions that capitalize on the strengths of the organization. Among new initiatives being considered are programs that partner education efforts with those being developed as part of several large research programs, curriculum modules that will promote teaching earth sciences

  4. Reflections on an AGU Congressional Science Fellowship

    NASA Astrophysics Data System (ADS)

    Fellows, Jack D.

    In spring 1983, prior to my fellowship year, I was finishing my National Aeronautics and Space Administration (NASA)—sponsored doctoral dissertation in hydrology at the University of Maryland. Currently, I am involved in the final budget deliberations for our nation's 1987 civilian space program in the Executive Office of the President (EOP). With this transformation in mind, I think it is fair to say that my 1983-1984 AGU Congressional Science Fellowship has had a tremendous influence on my career.During my fellowship in Congress, I worked with Rep. George E. Brown (D-Calif.) on water, remote sensing, space, and general science budgets and issues. I was involved in several pieces of legislation that are currently being implemented. It was through my responsibility for analysis of NASA programs and budget that I began to understand the complexity of the budget process and the development of our nation's civilian space policy. I found it very satisfying to learn about space programs beyond my own field of satellite-based hydrology.

    2010-08-01

    The AGU Council is the governing body responsible for science issues and is chaired by the Union president-elect (for more information, visit http://www.agu.org/about/governance/). The newly expanded Council includes the 24 focus group chairs and vice-chairs; 22 section presidents and presidents-elect; five committee chairs; four student/early-career scientists; and two ex officio members, the AGU president and the executive director. Council members elected their leadership team, which develops and oversees the work of the Council and defines issues of importance for Council deliberation. The Council will initially focus on how best to organize AGU science. This process will involve broad solicitation of insight into how Earth and space science is currently reconfiguring itself and how it is anticipated to change in the foreseeable future. That insight will be used to consider implications for how AGU structures itself, fulfills its purpose, and achieves its vision.

  9. First Scholarship at AGU Established by David E. Lumley

    Tahar, Joanna G.

    2009-09-01

    Shortly after AGU launched its annual voluntary contribution campaign last year—the theme was “Building Tomorrow's Talent Today”—the Union's development office received an e-mail message from David E. Lumley about establishing a scholarship for a high-school student or undergraduate. Many scientific societies and associations have quite a few named scholarships, but for AGU this was a new concept. Lumley was sure of what he wanted to do and even more excited when he learned that his scholarship would be a first for AGU. “I want to help inspire today's young minds to work on problems of global importance in both the energy and environment sectors of industry and academia,” Lumley said. Recipients of the David E. Lumley Young Scientist Scholarship for Energy and Environmental Science will be expected to present a paper and to participate in various student activities at Fall Meeting. “Meeting some of the ‘giants’ of geoscience and getting their feedback on research is a big deal for these young students. We sometimes lose sight of this,” he said.

    2013-12-01

    In recent years, science has become inextricably linked to the political process. As such, it is more important now than ever for science to forge a better relationship with politics, for the health of both science and society. To help meet this need, the American Geophysical Union (AGU) strives to engage its members, shape policy, and inform society about the excitement of Earth and space science and its role in developing solutions for the sustainability of the planet. In June 2013, AGU held its second annual Science Policy Conference in Washington, D.C. The goal of the conference is to provide a new forum for diverse discussions and viewpoints on the challenges and opportunities of science policy, with a focus on applications of Earth and space science that serve local, national, and international communities. The meeting brought together more than 300 scientists, policy makers, industry professionals, members of the press, and other stakeholders to discuss the topics concerning the Arctic, climate change, oceans, energy, technology and infrastructure, and natural hazards science as they relate to challenges impacting society. Sessions such as 'The Water-Energy Nexus,' 'Potential for Megadisasters,' 'The Changing Ocean and Impacts on Human Health,' and 'Drowning and Drought: Agricultural Impacts of Climate Change' are examples of some of the intriguing and timely science policy issues addressed at the conference. The findings from the conference were used to develop a summary report. The report highlights key facts and figures to be used as a resource in discussions with policy makers and other stakeholders regarding the conference topics. This presentation will discuss the goals and outcomes of the conference and how the event represents one of the many ways AGU is approaching its 'Science and Society' priority objective as part of the Union's strategic plan; namely by increasing the effectiveness and recognition of AGU among policy makers as an authoritative

    AGU has begun the search for a new executive director to serve in partnership with AGU's elected leadership to build tomorrow's AGU—the contemporary scientific society envisioned by our members and needed for 2010 and beyond. This is a rare opportunity to take the helm of a highly respected, financially strong membership organization in a moment of transformation and help us achieve our goals to grow in impact. Reporting directly to the Board of Directors, the executive director is responsible for providing strategic vision, leadership, and overall management to the organization according to the direction set by AGU's elected leaders.

  13. AGU Council looks to the future

    NASA Astrophysics Data System (ADS)

    Precollege education was the focus of an important action taken by the AGU Council at its December 4, 1990, meeting in San Francisco. An expenditure of $50,000 was authorized to provide staff time to develop and implement programs in this area. The Union is looking forward to significant grant support for these education activities. With the funds the Education and Human Resources Committee hopes to improve the flow of students into the Earth and space sciences and generate an appreciation of science among all students and the general public.The Council also approved proceeding with plans for the construction of a new headquarters building. At current growth rates, the headquarters building will be full by 1994. After an extended study of a wide range of alternatives, the Ad Hoc Committee on Real Estate, chaired by Ned Ostenso, recommended that the current “obsolescent” building be demolished and a new and larger one built on the same site. While plans are being made for the next step in this process, a search will also be conducted for a suitable building in a good location in Washington that could be purchased at a reasonable price. The current state of the real estate market dictates keeping one's options open.

    AGU is an international Union of scientists, working together on a broad spectrum of scientific topics that span all of the Earth and space sciences. Our research encompasses everything from the exploration of the planets, to studies of the structure and chemical composition of the Earth's deep interior, to understanding the Earth's atmosphere and the causes of climate change. These are not only exciting scientific topics but many of the problems that we are working on are of great interest and relevance to people all over the world. The Outreach programs and activities at AGU inform and educate the public about the Earth and space sciences, foster a strong and diverse Earth and space science workforce, and provide expertise to serve as a basis for the development of public policy. AGU offers a variety of Outreach programs and activities associated with the meetings as well as in other venues. We will present examples of these; discuss what has worked and what presents difficulties; and propose concepts for future directions in education, public information and public affairs.

    Over the past 2 years, AGU has undertaken two critical initiatives designed to better position the organization for continued success. The first was a full membership vote to restructure governance to better address how both the science and the business of AGU are conducted. The second was to create a new long-term strategic plan based on broad input from a cross section of science perspectives. Now the newly configured AGU Council, which represents all constituent voices, is focusing on a key question: Given our strategic plan, stakeholder expectations of AGU, and what is being asked of science and our members, how does our science need to be organized, recognized and rewarded, disseminated, and promoted?

    Imagine the United States without Los Angeles. That was the unnerving hypothetical posed by Lucile Jones to an audience of more than 100 people at AGU's annual public lecture on the opening day of the 2013 Fall Meeting. As the science advisor for risk reduction with the U.S. Geological Survey, Jones is a familiar face to many Californians—she is often interviewed in the wake of the state's frequent earthquakes. In her lecture, Jones explained that there is a high likelihood that a major quake will hit the Los Angeles region.

  2. Shaping AGU's contributions to policy debate

    NASA Astrophysics Data System (ADS)

    Morgan, M. Granger; Patwardhan, Anand

    In their Forum piece in the April 9 issue of Eos, Kaula and Anderson paint an unrealistically stark choice for the roles AGU might play in policy debates that substantially involve geophysical science. On the one hand is the antiseptic model of AGU-above-the-policy-fray: the aloof provider of geophysical facts from the literature. On the other hand is the model of AGU-as-policy-advocate: blending geophysical knowledge with value judgements in order to argue for specific policy actions in the political trenches. The problem with the first model is that the form assumed by most geophysical facts in the literature is rather distant from the needs of policy makers. Thus, the facts are easily overlooked in the face of pressing short-term political agendas. The problem with the second model is that AGU is a professional society comprised of scientists who hold many different value orientations. Any particular set of values adopted in a piece of political advocacy is likely to be at odds with many AGU members.

    After 39 years as AGU executive director, Fred Spilhaus has stepped down from his post; he will become executive director emeritus. At a 27 January 2009 staff meeting at AGU headquarters, in Washington, D. C., three of the Union officers introduced Robert T. Van Hook, who will serve as interim executive director while AGU conducts a worldwide search for a new executive director. The search is expected to start in the summer of 2009 and to take from 6 to 18 months. ``AGU is a growing, vibrant organization that wishes to thoughtfully chart its course for the coming decades,'' Van Hook said. ``I am a professional interim executive, here to build on Fred Spilhaus's legacy. I want to help this extraordinary Union of researchers, teachers, and students take careful stock of where it is today, where it wants to go tomorrow, and what kind of staff leader it needs to help it get there,'' he said. ``My job is to get you ready for the next executive director,'' Van Hook told AGU staff, noting that he is not a candidate for the position himself.

    The Stanford SOLAR Center in a coordinated effort with the AGU-SPA Education Committee is developing a Presentation Bank to provide AGU Space Physics and Aeronomy scientists with collected materials & imagery to present Sun-Earth related science in their field of expertise to the general public. The presentations can also be used for other audiences such as school groups, science museums, planetariums and the press. Working closely with the Education Committee and SPA scientists we are enhancing the existing SPA "slideset" into a prototype demonstration of the Presentation Bank. Our focus is to use up to date "best of" imagery and video to excite an audience about current research topics. By following a peer review process, the best and most useful collection of imagery will be produced to meet the needs of AGU scientists. We will share samples of slideset imagery and discuss details and infrastructure of the presentation bank and how scientists can best use this resource.

    On Wednesday, 7 September 2011, two weeks after the magnitude 5.8 earthquake in Mineral, Va., and a week after Hurricane Irene struck the U.S. East Coast, AGU cosponsored a showcase of National Science Foundation (NSF)—funded hazards research in recognition of National Preparedness Month. This annual event highlights NSF—funded hazards research from all over the United States, with more than 30 exhibitors demonstrating the latest research and technology on hurricanes, earthquakes, tornadoes, volcanoes, tsunamis, and oil spills, as well as emergency and social responses to these events. The event took place at the Hart Senate Office Building, where many members of Congress and their staff could attend and discuss the importance of hazards research with the researchers and NSF staff. Sen. Bill Nelson (D-Fla.) kicked off with a panel of speakers, which included remarks by Mary Voytek, a member of the AGU Board of Directors, and Subra Suresh, director of NSF. Expert presentations were also given on hazard prediction, human safety, and social response. Following the event, Senate Majority Leader Harry Reid (D-Nev.) hosted a small event to meet directly with a few of the exhibitors to discuss the importance of investment in scientific research and development.

    NASA Astrophysics Data System (ADS)

    2014-11-01

    The E-MRS 2014 Spring meeting, held from 26-30th May 2014 in Lille included the Symposium D entitled ''Phonons and Fluctuations in Low Dimensional Structures'', the first edition of its kind. The symposium was organised in response to the increasing interest in the study of phonons in the context of advances in condensed matter physics, electronics, experimental methods and theory and, in particular, the transfer of energy across atomic interfaces and the propagation of energy in the nm-scale. Steering heat by light or vice versa and examining nano-scale energy conversion (as in thermoelectricity and harvesting e.g. in biological systems) are two aspects that share the underlying science of energy processes across atomic interfaces and energy propagation in the nanoscale and or in confined systems. The nanometer scale defies several of the bulk relationships as confinement of electrons and phonons, locality and non-equilibrium become increasingly important. The propagation of phonons as energy carriers impacts not only heat transfer, but also the very concept and handling of temperature in non-equilibrium and highly localised conditions. Much of the needed progress depends on the materials studied and this symposium targeted the interface material aspects as well as the emerging concepts to advance in this field. The symposium had its origins in a series of meetings and seminars including: (1) the first Phonon Engineering Workshop, funded by Catalan Institute for Research and Advanced Studies (ICREA), the then MICINN, the CNRS, VTT, and several EU projects, held in Saint Feliu de Guixols (Girona, Spain) from 24th to 27th of May 2010 with 65 participants from Europe, the USA and Japan; (2) the first Phonons and Fluctuations workshop, held in Paris on 8th and 9th November 2010, supported by French, Spanish and Finnish national projects and EU projects, attended by about 50 researchers; (3) the second Phonon and Fluctuations workshop, held in Paris on 8th and 9th

    Based largely on a publication titled A Guide for Providing Scientific Testimony by Arthur Jack Grimes, Head, Department of Public Responsibilities, American Institute of Biological Sciences.NB. All price quotes for publications are 1983 prices.The purpose of this guide is to assist AGU members in communicating with legislators and government agency officials and to delineate some of the constraints under which AGU must operate when undertaking activities in this area.Before becoming law and having funds appropriated to carry it out, legislation at the federal level and at most state levels can go through more than 20 different steps. Certain steps offer opportunity for persons and groups to provide information with both written and inperson testimony. A few of the key steps in the legislative process are presented.

    There is convincing evidence that soft tissue and other biomolecules can survive long periods of fossilization by their interaction with blood iron and/or carbonate absorption. Here are presented the results of investigations showing that ancient biomolecules and their decay products contain significantly more pMC's (% modern 14C) than diamond and coal presented during a poster session held at the AGU 2003 SF convention. The title was: The Enigma of the Ubiquity of 14C in organic samples older than 100,000 K. The given range for five diamonds from Botswana and South Africa ranged from 0.096 to 0.146 pMC. Ten coal specimens from the United States from the Eocene to Pennsylvanian geologic interval yielded 0.1 to 0.46 pMC's. In our extensive field and lab study ten dinosaurs from Texas to Alaska, and China yielded much higher pMC's of 0.76 to 5.59 after pretreatment to remove modern contaminants. When 2g of a Belgium Mosasaur from Europe was pretreated to remove contaminants the pMC was 4.68 or 24,600 RC years on Lund Un AMS in Sweden (Lindgren et al. 2011, PloS ONE, page 9). The endogenous sources of dinosaur pMC's were further enhanced by the δ13C range of -20.1 to -23.8 for collagen, 16.6-28.4 for bulk organic and -3.1 to -9.1 for CO3 fractions. The δ13C values compare favorably to δ13C values of -23 to -27 in a similar study of dinosaur δ13C values from the Judith River formation in Alberta, Canada that (Ostrom et al. 1993, Geology, v. 21). . Diamonds from South America (Taylor-Southon, Nuclear Instruments 2007 ) yielded ages of 66,000 to 80,000 years leaving little doubt that at least the dinosaur ages of 22,020 ± 50 to 39,230 ± 140 were not machine error or a result of contamination anymore than the coal samples. This data explains more clearly why such biomolecules have persisted and therefore should not be ignored as the implications are of utmost importance to science and humanity. Thus the experimental results presented here demonstrate the need for

    Fast action by Headquarters alerted AGU members to a proposed change to the National Science Foundation's page charge policy that would weaken the ability of scientific societies to serve the scientific community.If adopted, NSF's new policy, announced in the Federal Register December 18, would remove the prohibition against allowing page charges to commercially produced journals. The proposal for the change was supposedly put forth to obtain a reaction from the scientific community.

    NASA Astrophysics Data System (ADS)

    Simarski, Lynn Teo

    On May 1, before a standing-room-only House hearing, Representative Barbara Boxer (D-Calif.) hammered hard questions at Richard Truly, administrator of the National Aeronautics and Space Administration, over the cost of the redesigned Space Station Freedom. AGU President G. Brent Dalrymple was also invited to testify about the station's cost and scientific merit as part of an expert panel before the House Government Operations subcommittee on government activities and transportation. Other witnesses included another AGU member, Louis J. Lanzerotti, chairman of the Space Studies Board of the National Research Council.The hearing, which ran three-and-a-half intense hours, dealt with new estimates of Freedom's cost that are well in excess of NASA's $30 billion figure for the revised design. Charles A. Bowsher, U.S. comptroller general, testified about a new study by the General Accounting Office that estimates a $118 billion cost for the station, more than triple NASA's figure. AGU's testimony and the subcommittee's staff both projected an even higher figure—$180 billion—although they used different assumptions to reach it.

    Since twenty years, many nanoparticles based on high atomic number elements have been developed as radiosensitizers. The design of these nanoparticles is limited by the classical rules associated with the development of nanoparticles for oncology and by the specific ones associated to radiosensitizers, which aim to increase the effect of the dose in the tumor area and to spare the health tissues. For this application, systemic administration of nanodrugs is possible. This paper will discuss the development of AGuIX nanoparticles and will emphasize on this example the critical points for the development of a nanodrug for this application. AGuIX nanoparticles display hydrodynamic diameters of a few nanometers and are composed of polysiloxane and gadolinium chelates. This particle has been used in many preclinical studies and is evaluated for a further phase I clinical trial. Finally, in addition to its high radiosensitizing potential, AGuIX display MRI functionality and can be used as theranostic nanodrug for personalized medicine. PMID:26343033

    New technologies, such as the emerging field of geoneutrino research, and new data sets from the Cassini and Voyager spacecrafts have captured the attention of scientists, prompting them to freshly explore the furthest reaches of their fields, from the Earth's deep interior to the outer solar system and beyond. Several sessions at the 23-26 May 2006 AGU Joint Assembly in Baltimore, Md., will offer a glimpse into these new investigations, while others are devoted to discussing plans for coordinated research efforts during upcoming international science years. One session on ``Geoneutrinos: A New Tool for the Study of the Solid Earth'' (U41F) will take place on Wednesday, 25 May at 8:30 A.M. Geoneutrinos, which are anti-neutrinos produced by the radioactive decay of uranium, thorium, and potassium housed within the Earth, have been detected by Japan's Kamioka Liquid-Scintillator Anti-Neutrino Detector (KamLAND) apparatus. With such information, scientists for the first time can directly estimate the amount of radioactive elements present in different regions of the Earth.

NVAG3 was joint American Geophysical Union Chapman and European Geophysical Society Richardson Memorial conference, the first specialist conference jointly sponsored by the two organizations. It followed NVAG1 (Montreal, Aug. 1986), NVAG2 (Paris, June 1988; Schertzer and Lovejoy, 1991), five consecutive annual sessions at EGS general assemblies and two consecutive spring AGU meeting sessions. As with the other conferences and workshops mentioned above, the aim was to develop confrontation between theories and experiments on scaling/multifractal behaviour of geophysical fields. Subjects covered included climate, clouds, earthquakes, atmospheric and ocean dynamics, tectonics, precipitation, hydrology, the solar cycle and volcanoes. Areas of focus included new methods of data analysis (especially those used for the reliable estimation of multifractal and scaling exponents), as well as their application to rapidly growing data bases from in situ networks and remote sensing. The corresponding modelling, prediction and estimation techniques were also emphasized as were the current debates about stochastic and deterministic dynamics, fractal geometry and multifractals, self-organized criticality and multifractal fields, each of which was the subject of a specific general discussion. The conference started with a one day short course of multifractals featuring four lectures on a) Fundamentals of multifractals: dimension, codimensions, codimension formalism, b) Multifractal estimation techniques: (PDMS, DTM), c) Numerical simulations, Generalized Scale Invariance analysis, d) Advanced multifractals, singular statistics, phase transitions, self-organized criticality and Lie cascades (given by D. Schertzer and S. Lovejoy, detailed course notes were sent to participants shortly after the conference). This

    The world is a very different place than it was 43 years ago. In 1969, Jimi Hendrix rocked the legendary Woodstock music festival, Neil Armstrong took the first steps on the Moon, and U.S. drivers paid an average of 35 cents a gallon for gas. Today, digital music files have replaced vinyl records, NASA's Curiosity rover is transmitting data and imagery from the surface of Mars, and a growing number of cars run on alternative fuels. In the same way, 43 years ago AGU was a very different organization. Membership hovered around 10,000, and the Fall Meeting was still in its infancy. Today, AGU's membership has increased to more than 61,000, Fall Meeting attendance has topped 20,000, and an entire generation of geoscientists who weren't even born in 1969 now comprises 28% of our current membership.

    Since 1982, AGU has developed and maintained position statements to provide scientific expertise on significant policy issues. All members are encouraged to help inform the policy-making process in their home and research locales with thoughtful presentation of scientific viewpoints. To aid in this task, AGU members may use an AGU position statement as an official statement of the Union in discussion with policy makers. Position statements are published on the AGU science policy Web page, where they can be viewed by scientists, policy makers, media, and the general public.

    Fast publication and high quality and impact are important for effective dissemination of geoscience research. With this in mind, AGU's journal editors and staff, along with staff at our publishing partner, Wiley, have been working to increase both the speed of publication and the impact of the research published in our 18 peer-reviewed journals while maintaining our commitment to quality. Significant progress continues to be made on both fronts, as evidenced by the most recent publication times and the 2013 release of the Journal Citation Reports®, which was issued by Thomson Reuters on 29 July.

    2012-06-01

    Almost 2 years ago, AGU began investigating how it could more efficiently manage member and customer records as well as support processes that currently run on multiple systems. I am pleased to announce that on 25 June, as the result of intense efforts, AGU will migrate to a new database software system that will house the majority of AGU operations. AGU staff will have more tools at their disposal to assist members, and members will have more intuitive and user-friendly options when using the online interface to update their profiles or make purchases. I am particularly excited about this major improvement to our infrastructure because it better positions AGU to achieve goals in its strategic plan.

  12. CO2 Emissions from Air Travel by AGU and ESA Conference Attendees

    NASA Astrophysics Data System (ADS)

    Scott, B.; Plug, L. J.

    2003-12-01

    Air travel by scientists is one contributor to rising concentrations of CO2 and other greenhouse gases in the atmosphere. To assess the magnitude of this contribution in per-capita and overall terms, we calculated emissions derived from air travel for two major scientific conferences held in 2002: the western meeting of the American Geophysical Union (AGU) in San Francisco and the Ecological Society of America meeting in Tucson (ESA). Round trip travel distance for sampled attendees is 7971 +/- 6968 km (1 sigma range given, n=337) for AGU and 5452 +/- 5664 km for ESA (n=263), conservatively assuming great circle routes were followed. Using accepted CO2 production rates for commercial aircraft, mean AGU emissions are 1.3 tonnes per attendee and 12351 tonnes total and for ESA 0.9 tonnes per attendee and 3140 tonnes total. Although small compared to total anthropogenic emissions (2.275 x 1010 tonnes y-1 in 1999), per attendee emissions are significant compared to annual per-capita emissions; CO2 emission per AGU and ESA attendee exceeds the per capita annual emission of 42% and 19% of Earth's population, respectively. Per attendee AGU emissions are ≈6% of U.S. and ≈14% of British and Japanese per capita annual emission. Relocation of AGU and ESA to cities which minimize travel distances, Denver and Omaha respectively, would result in modest emission reductions of 8% and 14% (assuming 2002 attendee composition). To form a preliminary estimate of annual CO2 emissions for scientists in academia, we surveyed Earth Science faculty at our home institution. Mean annual air travel distance for professional activities was 38064 km y-1 (7 respondents). The consequent release of 6.1 tonnes y-1 of CO2 is 30% of annual per capita emissions in North America, and exceeds global per capita average of 4 tonnes y-1 by 150%. Society and the environment often benefit from scientific enquiry which is facilitated by travel. These benefits, however, might be balanced against the

    On 1 February 2012, AGU teamed with 11 other scientific societies to bring 29 scientists researching various aspects of climate change to Washington, D. C., for the second annual Climate Science Day on Capitol Hill. The participants represented a wide range of expertise, from meteorology to agriculture, paleoclimatology to statistics, but all spoke to the reality of climate change as demonstrated in their scientific research. With Congress debating environmental regulations and energy policy amid tight fiscal pressures, it is critical that lawmakers have access to the best climate science to help guide policy decisions. The scientists met with legislators and their staff to discuss the importance of climate science for their districts and the nation and offered their expertise as an ongoing resource to the legislators.

    2010-11-01

    A veteran Indian reporter and a rookie science writer have won AGU's 2010 journalism awards. Pallava Bagla will receive the David Perlman Award for Excellence in Science Journalism-News for two articles he wrote about the impact of climate change on Himalayan glaciers. The first of his articles, “No sign yet of Himalayan meltdown, Indian report finds,” published in Science, explores dissent among glaciologists regarding a passage in the Fourth Assessment Report of the United Nations Intergovernmental Panel on Climate Change (IPCC). The passage suggests that Himalayan glaciers are highly likely to disappear by 2035. His second article, “Himalayan glaciers melting deadline ‘a mistake,’” published by BBC News, discusses a possible typographical error in the disputed passage. In the article, Bagla indicates that this error appears to explain the panel's controversial acceleration of when Himalayan glaciers are expected to vanish.

    Science and technology were an essential part of all of the energy issues I worked on during my year as AGU Congressional Fellow in the office of U.S. senator Byron L. Dorgan (D-N. D.), chair of the Senate Appropriations Subcommittee on Energy and Water Development and a senior member of the Senate Committee on Energy and Natural Resources. During my fellowship year, which lasted from September 2009 through September 2010, I found that no one on Capitol Hill in Washington doubted the utility of science in addressing issues such as hydraulic fracturing for oil and gas production, the electrification of the transportation fleet, the Deepwater Horizon oil spill in the Gulf of Mexico, and carbon capture and sequestration. However, during the year, two subjects were the focus of a broader questioning of science in Congress: “Climategate” and metrics to justify federal investment in research.

    2011-09-01

    On 17 August the AGU Council voted to adopt an American Meteorological Society (AMS) statement on free and open communication of scientific findings as an official position of AGU. The statement appears below. Recent attacks on scientists who present facts that are controversial or politically charged, such as in cases involving climate science, have sparked action by AGU and other scientific societies, including the American Association for the Advancement of Science. Open communication and collaboration are essential to the scientific process and must not be deterred by politics, media, or faith. In a recent letter to the New York Times, AGU president Michael McPhaden stated that “misguided attempts to suppress scientific research, particularly through political pressure, will not make climate change or the role human activity plays in it magically disappear. It will, however, make the objective knowledge needed to inform good policy decisions disappear.”

    More than Moore explores a new area of Silicon based microelectronics, which reaches beyond the boundaries of conventional semiconductor applications. Creating new functionality to semiconductor circuits, More than Moore focuses on motivating new technological possibilities. In the past decades, the main stream of microelectronics progresses was mainly powered by Moore's law, with two focused development arenas, namely, IC miniaturization down to nano scale, and SoC based system integration. While the microelectronics community continues to invent new solutions around the world to keep Moore's law alive, there is increasing momentum for the development of 'More than Moore' technologies which are based on silicon technologies but do not simply scale with Moore's law. Typical examples are RF, Power/HV, Passives, Sensor/Actuator/MEMS or Bio-chips. The More than Moore strategy is driven by the increasing social needs for high level heterogeneous system integration including non-digital functions, the necessity to speed up innovative product creation and to broaden the product portfolio of wafer fabs, and the limiting cost and time factors of advanced SoC development. It is believed that More than Moore will add value to society on top of and beyond advanced CMOS with fast increasing marketing potentials. Important key challenges for the realization of the 'More than Moore' strategy are: perspective materials for future THz devices materials systems for embedded sensors and actuators perspective materials for epitaxial approaches material systems for embedded innovative memory technologies development of new materials with customized characteristics The Hot topics covered by the symposium M (More than Moore: Novel materials approaches for functionalized Silicon based Microelectronics) at E-MRS 2012 Spring Meeting, 14-18 May 2012 have been: development of functional ceramics thin films New dielectric materials for advanced microelectronics bio- and CMOS compatible

    Robert Van Hook, who served as AGU's interim executive director since January 2009, led the organization during a transition period that began with the retirement of long-serving executive director A. F. (“Fred”) Spilhaus Jr. Van Hook's tenure concluded on 30 August when Christine McEntee assumed her position as AGU's new executive director (see Eos, 91(17), 153, 156, 2010). During his tenure at AGU, which overlapped with a global economic recession, Van Hook helped to guide the organization through key structural governance changes, strategic planning, and upgrades in technology, human resources, and accounting. He also helped to revitalize public outreach and member services, among many other efforts. Van Hook, president of Transition Management Consulting, recently reflected upon his tenure, the transition period, and the future of AGU. Van Hook credits AGU's strong volunteer leadership—including past presidents Tim Killeen and Tim Grove, current president Mike McPhaden, and president-elect Carol Finn—for courage in moving the organization through a successful transition. “They were the ones who shoved the boat off from the shore. I was lucky enough to be invited into the boat,” he said. He also credits the staff for their resiliency and commitment to supporting AGU's science.

    A lot has happened in a little more than 2 years, and we want give AGU members an update on how things are working under AGU's strategic plan and governance model. AGU is an organization committed to its strategic plan (http://www.agu.org/about/strategic_plan.shtml), and if you have not read the plan lately, we encourage you to do so. AGU's vision is to be an organization that "galvanizes a community of Earth and space scientists that collaboratively advances and communicates science and its power to ensure a sustainable future." We are excited about the progress we have made under this plan and the future course we have set for the Union. Everything the Board of Directors, Council, and committees put on their agendas is intended to advance AGU's strategic goals and objectives. Together with headquarters staff, these bodies are working in an integrated, effective manner to carry out this plan. The best way to demonstrate the progress made and each group's role is to walk through a recent example: the creation of a new Union-level award (see Figure 1).

    2010-11-01

    This special issue contains selected papers which were presented at the E-MRS Symposium BIOMATERIALS, SENSORS & SURFACES, D: 'Surface modifications of diamond and related materials' which was held on 7-9 June 2010 in Strasbourg (France). With about 54 oral and poster presentations given from teams all over the world it was a very interesting, dense and lively meeting. The symposium focused on chemical modifications applied to graft surfaces of diamond, nano-diamond particles, diamond-like carbon, graphene, graphite and carbon nano-tubes with linker molecular layers for realization of bio-sensors, bio-markers, separation techniques, and switchable chemical links. Presented techniques span spontaneous bonding to photo-chemical attachment, electrochemical modifications, to Suzuki-coupling of aryl molecules. Special attention was drawn to mechanisms driving bonding kinetics such as electron transfer reactions, hydrogen cleavage reactions by nucleophilic molecules and growths schemas which vary from correlated two-dimensional chain reactions to three-dimensional cross polymerization. Hydrogen terminations, surface defects, surface roughness and atomic arrangements of surface carbon atoms were of interest to elucidate bonding mechanisms. In addition, bonding stability, either of linker molecules or of complex functionalized surfaces with DNA, proteins and enzymes was discussed by several speakers as well as details of the electronic interfaces between solid transducers and bio-layers. Here the characterization of surface and interface defect densities, of Fermi level pinning and of electron transfer rates was a major topic. Miniaturization of sensor area and application of new detection schemas was discussed. Diamond nano-particles which are increasingly used as biomarkers in drug delivery experiments also attracted attention. The organizers express our gratitude to the international members of the scientific committee who actively contributed to ensure an attractive

  8. The Gaia Controversy: AGU'S Chapman Conference

    NASA Astrophysics Data System (ADS)

    Kauffman, Eric G.

    The controversial Gaia Hypothesis of James Lovelock of Coombe Mill, Launceston, Cornwall, U.K., and his colleagues variously contends that throughout Earth history the global biosphere has influenced, even controlled, the physicochemical evolution of Earth's environments (especially oceans and climate) for its own benefit. Since the origin of life, the biosphere has influenced selective pressures on evolution, maintained the Earth in a kind of homeostasis, and thus created an environmental optimum through time, regulated by and for the biosphere. Rarely has a hypothesis immediately sparked such passionate response. There is something in it for everybody, from hard core scientists to philosophers, ultraconservationists, students of world religions, mystics, politicians, and space enthusiasts; they were all there in San Diego, March 7-11, 1988, for the AGU Chapman Conference on Gaia Hypotheses. For 4 days an impressive list of specialists presented and debated the pros and cons of Gaia Hypotheses from diverse perspectives: modern and ancient biology, ecology, biochemistry, the physicochemical systems of the Earth, oceans, and atmosphere, and the evolution of the solar system. Focus was on modern to Pleistocene atmosphere-ocean-Earth systems, case histories of their interaction with the biosphere, and relatively simple models drawn from these observations and projected back through time. Equivalent studies on the geological and paleobiological history of the Earth-life system over the past 3.5 b.y. were underrepresented. Extended debates that followed generally strong presentations were lively, argumentative, and remarkably civil despite widely held views. The grace with which Jim Lovelock moved between his strongest critics and supporters set high standards for the debates. Everybody acknowledged a high learning curve.

On this poster, and in the accompanying review paper, we will present an overview of the work presented in the last 7 years, cataloging the work of the inventive scientists who have contributed to these successful, and above all: fun, sessions.

  10. [comment t[Comment on] “What is AGU's proper role in society?”] AGU's role in society: Duty to the public

    NASA Astrophysics Data System (ADS)

    Wilshire, Howard

    Bravo to William Kaula and Don Anderson for their forthright opinion, “What Is AGU's Proper Role in Society?” (Eos, April 9, 1991). In hearing preliminaries about Mission to Planet Earth at the Geological Society of America's meeting in Phoenix in 1987, I was turned off by what seemed to me to be endless self-serving proposals to probe the Earth “with our steely knives,” but with hardly a mention of how we could use the information to assist the nation in making rational decisions about the future human occupancy of Earth. I concur with Kaula and Anderson that it is not only the duty of individual scientists to speak out on controversial issues of public concern, but also the duty of professional societies to influence the public policy decision-making process in areas where our special expertise is relevant.It does not matter that opinions within the professional societies differ. Opinions within the nation differ, too. But to take no position at all because of these differences of opinion is dereliction of our duty to the public that supports us. AGU already has a mechanism for presenting a Union-endorsed position on public issues (which could serve as a model for other professional societies whose best effort is to hide under the bed). This mechanism needs to be used more aggressively so that our expert knowledge (both of facts and hypotheses) is brought to bear on matters of critical human concern.

    This volume of IOP Conference Series: Materials Science and Engineering contains papers that were presented at the special symposium K at the EMRS 2009 Spring Meeting held 8-12 June in Strasbourg, France, which was entitled 'Semiconductor Nanostructures towards Electronic and Optoelectronic Device Applications II'. Thanks to the broad interest a large variety of quantum dots and quantum wires and related nanostructures and their application in devices could be covered. There was significant progress in the epitaxial growth of semiconductor quantum dots seen in the operation of high-power, as well as mode locked laser diodes and the lateral positioning of quantum dots on patterned substrates or by selective area growth for future single quantum dot based optoelectronic and electronic devices. In the field of semiconductor nanowires high quality, almost twin free structures are now available together with a new degree of freedom for band structure engineering based on alternation of the crystal structure. In the search for Si based light emitting structures, nanocrystals and miniband-related near infrared luminescence of Si/Ge quantum dot superlattices with high quantum efficiency were reported. These highlights, among others, and the engaged discussions of the scientists, engineers and students brought together at the symposium emphasize how active the field of semiconductor nanostructures and their applications in devices is, so that we can look forward to the progress to come.

    2012-10-01

    With the "fiscal cliff" of sequestration drawing closer and threatening to hit basic science research funding with an 8.2% cut, according to an estimate by the Office of Management and Budget, congressional compromise on a budget plan is more urgent than ever. To discuss the value of scientific research and education with their senators and representatives, 55 Earth and space scientists from 17 states came to Washington, D. C., on 11-12 September to participate in the fifth annual Geosciences Congressional Visits Day sponsored by AGU and six other geoscience organizations. Although their specialties varied from space weather to soil science, the scientists engaged members of Congress and their staff in a total of 116 meetings to discuss a common goal: securing continued, steady investment in the basic scientific research that allows scientists to monitor natural hazards, manage water and energy resources, and develop technologies that spur economic growth and job creation. To make the most of these visits on 12 September, participants attended a training session the previous day, during which they learned about the details of the policy- making process and current legislative developments and practiced conducting a congressional meeting. Congressional Science Fellows, including past AGU fellow Rebecca French, described their experiences as scientists working on Capitol Hill, and White House policy analyst Bess Evans discussed the president's stance on sequestration and funding scientific research.

    . Igel, W.H.K. Lee, and M. Todorovska during the 2006 AGU Fall Meeting. The goal of this session was to discuss rotational sensors, observations, modeling, theoretical aspects, and potential applications of rotational ground motions. The session was accompanied by the inauguration of an International Working Group on Rotational Seismology (IWGoRS) which aims to promote investigations of all aspects of rotational motions in seismology and their implications for related fields such as earthquake engineering, geodesy, strong-motion seismology, and tectonics, as well as to share experience, data, software, and results in an open Web-based environment. The primary goal of this article is to make the Earth Science Community aware of the emergence of the field of rotational seismology.

    Lactococcus lactis subsp. cremoris CECT 8666 (formerly GE2-14) is a dairy strain that catabolizes agmatine (a decarboxylated derivative of arginine) into the biogenic amine putrescine by the agmatine deiminase (AGDI) pathway [1]. The AGDI cluster of L. lactis is composed by five genes aguR, aguB, aguD, aguA and aguC. The last four genes are responsible for the deamination of agmatine to putrescine and are co-transcribed as a single policistronic mRNA forming the catabolic operon aguBDAC[1]. aguR encodes a transmembrane protein that functions as a one-component signal transduction system that senses the agmatine concentration of the medium and accordingly regulates the transcription of aguBDAC[2], which is also transcriptionally regulated by carbon catabolic repression (CCR) via glucose, but not by other sugars such as lactose and galactose [1], [3]. Here we report the transcriptional profiling of the aguR gene deletion mutant (L. lactis subsp. cremoris CECT 8666 ∆aguR) [2] compared to the wild type strain, both grown in M17 medium with galactose as carbon source and supplemented with agmatine. The transcriptional profiling data of AguR-regulated genes were deposited in the Gene Expression Omnibus (GEO) database under accession no. GSE59514. PMID:26697381

    Biological oceanographer Jana Davis is AGU's Congressional Science Fellow for 2004-2005. She will spend the year in the office of U. S. Senator Frank Lautenberg (D-N. J.), working on ocean and other environment issues. Davis received her Ph.D. in 2000 from the Scripps Institution of Oceanography in San Diego, California, and most recently was with the Maritime Studies Program, Williams College-Mystic Seaport in Connecticut, and the Smithsonian Environmental Research Center in Maryland. She is AGU's 28th Congressional Science Fellow. Davis applied for the fellowship in order to focus on policy at this point in her career. She observed, ``I feel that cases in which policy might benefit from increased incorporation of science outnumber those in which science lags policy.'' Davis said that the fellowship will ``provide the ideal educational experience'' to learn how policy makers struggle to ``balance current human need with future human and ecological value.''

  18. Molecular Characterization and Regulation of the aguBA Operon, Responsible for Agmatine Utilization in Pseudomonas aeruginosa PAO1

    2001-01-01

    Pseudomonas aeruginosa PAO1 utilizes agmatine as the sole carbon and nitrogen source via two reactions catalyzed successively by agmatine deiminase (encoded by aguA; also called agmatine iminohydrolase) and N-carbamoylputrescine amidohydrolase (encoded by aguB). The aguBA and adjacent aguR genes were cloned and characterized. The predicted AguB protein (Mr 32,759; 292 amino acids) displayed sequence similarity (≤60% identity) to enzymes of the β-alanine synthase/nitrilase family. While the deduced AguA protein (Mr 41,190; 368 amino acids) showed no significant similarity to any protein of known function, assignment of agmatine deiminase to AguA in this report discovered a new family of carbon-nitrogen hydrolases widely distributed in organisms ranging from bacteria to Arabidopsis. The aguR gene encoded a putative regulatory protein (Mr 24,424; 221 amino acids) of the TetR protein family. Measurements of agmatine deiminase and N-carbamoylputrescine amidohydrolase activities indicated the induction effect of agmatine and N-carbamoylputrescine on expression of the aguBA operon. The presence of an inducible promoter for the aguBA operon in the aguR-aguB intergenic region was demonstrated by lacZ fusion experiments, and the transcription start of this promoter was localized 99 bp upstream from the initiation codon of aguB by S1 nuclease mapping. Experiments with knockout mutants of aguR established that expression of the aguBA operon became constitutive in the aguR background. Interaction of AguR overproduced in Escherichia coli with the aguBA regulatory region was demonstrated by gel retardation assays, supporting the hypothesis that AguR serves as the negative regulator of the aguBA operon, and binding of agmatine and N-carbamoylputrescine to AguR would antagonize its repressor function.

    This past December the streets of San Francisco, Calif., surrounding the Moscone Center were awash with a sea of Earth and space scientists attending the 45th consecutive AGU Fall Meeting, eager to share and expand their knowledge "for the benefit of humanity." As it has for many years, attendance at AGU's Fall Meeting—the largest gathering of Earth and space scientists in the world—continued to increase, this year passing the 24,000 mark. Attendees at the meeting, which took place on 3-7 December 2012, hailed from 97 countries; nearly 7000 of them were students. News from the Fall Meeting was carried in newspapers and on Web sites around the world, and the social media sphere lit up with talk of AGU and the Fall Meeting. It's even reported that for a short time we were a trending topic on Twitter.

  1. Fall Meeting abstract submission inspires science poetry

    When the 4 August deadline for submitting Fall Meeting abstracts passed, AGU had received more than 20,000 abstracts, a record-breaking number. The submission process had an unexpected by-product: It inspired some scientists to write haiku on Twitter. (Haiku is a form of Japanese poetry typically having three lines, the first with five syllables, the second with seven, and the third with five.) The following are examples of the haiku tweets, with the hashtag #AGU11AbstractHaiku. (For those who want to keep updated about the Fall Meeting on Twitter, the hashtag is #AGU11.)

  2. Implementing the peer review process in AGU publications

    Baum, P. J.

    1984-04-01

    Recently, Russell and Reiff [1984] presented a flow-diagram analysis of the AGU publication process indicating how publication delays naturally occur. Perhaps because o f space limitations, their diagram did not include some important control statements. For example, according to their diagram, all manuscripts are either published or enter an endless loop. In fact, many papers end up elsewhere: As fish wrappers, in filing cabinets, or in non-AGU publications. (Accepted papers can end up in the same places, but they have the advantage of having been published in an AGU journal.) Significantly, the number of times the paper passes through the submission-refereeing loop (NJ) is not just journal dependent. NJ also depends inversely on nD, the density of Dogma in the paper. We are concerned with the publication process also and are motivated by reports that NJ is unusually large in the case of certain distinguished colleagues, particularly when introducing new concepts or criticizing older approaches. Some suggestions are offered here to speed publication and consequently to assist in the smoother functioning of the scientific method in geophysics.

    Scientists interested in using their skills to work on problems of public importance should consider applying for an AGU Congressional Science Fellowship. The fellowship is an opportunity to directly influence high-priority public policy issues such as natural hazards mitigation, mineral and energy resources, air and water quality, and federal support for basic research. Following an intensive 2-week course on politics and the legislative process run by the American Association for the Advancement of Science, congressional fellows work for a year as staff members in the offices of a senator, representative, or congressional committee. Their duties as staff members may include writing legislation, advising on votes, organizing congressional hearings, meeting with lobbyists and constituents, and conducting legislative research, among other tasks.

    Understanding Earth and space science is important not only to AGU members. It is also critical to citizens making decisions in their private lives, to voters, and to policy makers and government officials whose actions shape global societies. AGU's education and outreach activities aim to bring Earth and space science to the world beyond the scientific community (see AGU's strategic plan: http://www.agu.org/about/strategic_plan.shtml). To support these objectives, some AGU sections have formed a specific Education and Public Outreach (E/PO) committee or working group (http://www.agu.org/education/professionals.shtml). These groups engage in activities that range from interacting with teachers to supporting media releases.

    Denis-Didier Rousseau smiles shyly when discussing his new role as the chair of AGU's Fall Meeting Program Committee. "I'm not used to giving interviews," he says. Nonetheless, he becomes very passionate as he begins to talk about his views on transdisciplinary science and its role in AGU meetings, on including more young scientists in planning meetings, and on the importance of virtual meetings. Rousseau, who is currently a visiting professor at Columbia University, sat with Eos to share his excitement about working with AGU.

    Birmingham, Thomas J.

    Recent letters in Forum by Ron Zwickl (Eos, April 15, 1986, p. 186) and C. T. Russell (Eos, July 1, 1986, p. 545) have addressed the proliferation of authors on papers in AGU journals. I assume that the authors have at least the Journal of Geophysical Research-Space Physics in mind, as both are frequent contributors to our journal (and highly valued referees as well!).There is no doubt in my mind that marginal participants sometimes end up in the bylines of papers we publish. In a few instances, I do not believe that all authors even read the final manuscript: if they did, they would exercise better quality control over the submitted product. I do not agree, however, that AGU should be responsible for determining authorship, even in a tangential way: its concern, manifest through its editors, should be that each article published represents a significant new contribution to the discipline. To me as editor, it's what comes after the byline that matters!

    It's hard to believe that it is again time to consider elections for AGU leadership positions. Just over 18 months ago, AGU launched a new governance model and strategic plan. Since then, the AGU Board of Directors, the AGU Council, and staff leaders have partnered with us, the members of the Governance Committee, to move AGU forward in the positive direction set by members. Much has been accomplished in a short time, and much is left to do to achieve AGU's envisioned future (see http://www.agu.org/about/mission.shtml). We need to elect the next set of leaders who can carry on the direction and vision set in motion by the Future Focus Task Force and the first group of Board and Council members tasked with guiding this new plan. This year, AGU members will elect leaders for the next term (2013-2014). Below is a synopsis of what we've been doing, along with a timeline for nominations and elections.

    2011-11-01

    In support of the new strategic plan, AGU has established a new task force to review, evaluate, and update the Union's policies on scientific misconduct and the process for investigating and responding to allegations of possible misconduct by AGU members. As noted by AGU president Michael McPhaden, "AGU can only realize its vision of `collaboratively advancing and communicating science and its power to ensure a sustainable future' if we have the trust of the public and policy makers. That trust is earned by maintaining the highest standards of scientific integrity in all that we do. The work of the Task Force on Scientific Ethics is essential for defining norms of professional conduct that all our members can aspire to and that demonstrate AGU's unwavering commitment to excellence in Earth and space science."

    Ford, Barbara Meyers

    2009-07-01

    The latest numbers released from Journal Citation Reports (JCR), published annually by Thomson Reuters, show large increases in the impact factor (IF) for several AGU journals. IFs are one way for publishers to know that readers have found their journals useful and of value in research. A journal's IF is calculated by taking the total number of citations to articles published by a given journal in the past 2 years and dividing it by the total number of papers published by the journal in the same time period. More generally, it can be seen as the frequency with which articles in a journal have been cited over the past year. The numbers speak for themselves (see Table 1).

  18. Institutional support for science and scientists: A perspective from the immediate past AGU President

    NASA Astrophysics Data System (ADS)

    Grove, T. L.

    2010-12-01

    There were a number of times during my term as AGU President (July 2008 - July 2010) when AGU scientists came under intense public scrutiny. During this presentation I will discuss these experiences as they relate to the topic of this session. The first event centered around the inquiry into the University of East Anglia Climatic Research Unit by the House of Commons Science and Technology Committee concerning the so-called Climategate emails. The second was when U.S. scientists came under fire under the guise of a tax fraud investigation by the Virginia State Attorney General. In the first event, climate change skeptics demanded that I take punitive action on the scientists involved in the scandal. In the second, I received requests from AGU members to speak out against the Virginia attorney general’s investigation. In both situations I felt poorly prepared and unable to act in a way that would place in AGU in a strong position and have a positive influence on the public debate. These experiences left me feeling that the interface between science and society is becoming increasingly complex. AGU must engage its membership to help shape policy, and inform society about solutions for sustainability, and we must allocate resources to support those functions. We think that a good policy strategy must be lean and targeted and that AGU needs to stick to its scientific messages. AGU is now grappling with those issues and we are partnering with policy makers and seeking input from our members.

  2. Fostering Diversity in the Earth and Space Sciences: The Role of AGU

    NASA Astrophysics Data System (ADS)

    Snow, J. T.; Johnson, R. M.; Hall, F. R.

    2002-12-01

    In May 2002, AGU's Committee on Education and Human Resources (CEHR) approved a new Diversity Plan, developed in collaboration with the CEHR Subcommittee on Diversity. Efforts to develop a diversity plan for AGU were motivated by the recognition that the present Earth and space science community poorly represents the true diversity of our society. Failure to recruit a diverse scientific workforce in an era of rapidly shifting demographics could have severe impact on the health of our profession. The traditional base of Earth and space scientists in the US (white males) has been shrinking during the past two decades, but women, racial and ethnic minorities, and persons with disabilities are not compensating for this loss. The potential ramifications of this situation - for investigators seeking to fill classes and recruit graduate students, for institutions looking to replace faculty and researchers, and for the larger community seeking continued public support of research funding - could be crippling. AGU's new Diversity Plan proposes a long-term strategy for addressing the lack of diversity in the Earth and space sciences with the ultimate vision of reflecting diversity in all of AGU's activities and programs. Four key goals have been identified: 1) Educate and involve the AGU membership in diversity issues; 2) Enhance and foster the participation of Earth and space scientists, educators and students from underrepresented groups in AGU activities; 3) Increase the visibility of the Earth and space sciences and foster awareness of career opportunities in these fields for underrepresented populations; and 4) Promote changes in the academic culture that both remove barriers and disincentives for increasing diversity in the student and faculty populations and reward member faculty wishing to pursue these goals. A detailed implementation plan that utilizes all of AGU's resources is currently under development in CEHR. Supportive participation by AGU members and

    Chapman, David S.

    The AGU 1991 Fall Meeting, held in San Francisco December 9-13, was the largest national AGU meeting ever held. Meeting participation continued the steady growth trend set throughout the previous decade. A total of 4,037 papers and posters were presented, and by Friday noon of the meeting over 5,500 members had registered.Several special events were scheduled to inform and engage members on societal and programmatic aspects of our science. AGU's Committee on Education and Human Resources sponsored an open forum that addressed opportunities and problems associated with dual-career couples. A discussion of NASA's strategic plan by Berrien Moore and Joseph Alexander drew a large audience, and a special session on societal aspects of the Mt. Pinatubo eruption drew an overflow crowd. Two special lectures— “Plumes, Plates, and Deep Earth Structure” by Don L. Anderson and “New Frontiers in Aeronomy: Effects of Global Atmospheric Change” by P. M. Banks-also drew overflow crowds.

    As scientists, AGU members understand the important role data play in finding the answers to their research questions: no data—no answers. The same holds true for the historians posing research questions concerning the development of the geophysical sciences, but their data are found in archival collections comprising the personal papers of geophysicists and scientific organizations. Now historians of geophysics—due to the efforts of the AGU History of Geophysics Committee, the American Institute of Physics (AIP), and the archivists of the Niels Bohr Library and Archives at AIP—have an extensive new data source: the AGU manuscript collection.

    Lifland, Jonathan

    Following the default of one of its major journal subscription agents, AGU has committed itself to providing campus-wide electronic access for 2003 to libraries whose journal orders are affected by the bankruptcy. The company, RoweCom Inc. of Westwood, Massachusetts, filed for Chapter 11 protection on 27 January 2003.RoweCom folded in December with nearly $80 million in unfulfilled orders which were destined to thousands of publishers. Subscription agents consolidate orders from libraries and transmit payments to publishers for journal subscriptions. The bankruptcy could cost AGU up to $700,000 in lost revenue in 2003, approximately 7% of AGU's gross institutional subscriptions.

  6. Highlights of Publications Committee Meeting

    NASA Astrophysics Data System (ADS)

    The Publications Committee has the responsibility for the oversight of the entire publications program of the Union. They are the chief advisors to the Council on all matters relating to publication policy and practice. The committee meets twice each year for an all-day review of current areas of concern relating to journals, books, and translations. At its April 22, 1987, meeting in Washington, D.C., the following actions were taken: Decided to alter the Information for Contributors to clarify the expectations of AGU with regard to journal papers that have more than one author.Agreed to take several steps to inform the AGU members about the responsibilities and authorities of AGU journal editors and to reinforce the responsibilities of reviewers and authors as they relate to papers published by AGU.Approved a mechanism for evaluating AGU journals against other journals that compete with AGU for authors and readers.Endorsed a proposal of the Budget and Finance Committee that defines the target for the Council-designated reserve fund for publications. Recommended to the Budget and Finance Committee that future budgets carry a specific designation for investment in new technology for the publications activities.Reaffirmed the policy that only one subscription per member be provided at the special member rate. Urged staff to review the pricing structure for single issues to make it easier for members to purchase the occasional single issue.Encouraged the Translations Board to develop further their proposal for a data base on materials available in translation. Also requested the Translations Board to investigate translation of Japanese scientific literature, especially in hydrology.Agreed to support the Education and Human Resources Committee proposal to Council for testing a high school magazine based on items published in Eos. Made several suggestions for ways to improve the proposal with regard to the content of the magazine.

  7. Spring Tire

    The spring tire is made from helical springs, requires no air or rubber, and consumes nearly zero energy. The tire design provides greater traction in sandy and/or rocky soil, can operate in microgravity and under harsh conditions (vastly varying temperatures), and is non-pneumatic. Like any tire, the spring tire is approximately a toroidal-shaped object intended to be mounted on a transportation wheel. Its basic function is also similar to a traditional tire, in that the spring tire contours to the surface on which it is driven to facilitate traction, and to reduce the transmission of vibration to the vehicle. The essential difference between other tires and the spring tire is the use of helical springs to support and/or distribute load. They are coiled wires that deform elastically under load with little energy loss.

    Schertzer, D.; Lovejoy, S.

    1. The conference The third conference on "Nonlinear VAriability in Geophysics: scaling and multifractal processes" (NVAG 3) was held in Cargese, Corsica, Sept. 10-17, 1993. NVAG3 was joint American Geophysical Union Chapman and European Geophysical Society Richardson Memorial conference, the first specialist conference jointly sponsored by the two organizations. It followed NVAG1 (Montreal, Aug. 1986), NVAG2 (Paris, June 1988; Schertzer and Lovejoy, 1991), five consecutive annual sessions at EGS general assemblies and two consecutive spring AGU meeting sessions. As with the other conferences and workshops mentioned above, the aim was to develop confrontation between theories and experiments on scaling/multifractal behaviour of geophysical fields. Subjects covered included climate, clouds, earthquakes, atmospheric and ocean dynamics, tectonics, precipitation, hydrology, the solar cycle and volcanoes. Areas of focus included new methods of data analysis (especially those used for the reliable estimation of multifractal and scaling exponents), as well as their application to rapidly growing data bases from in situ networks and remote sensing. The corresponding modelling, prediction and estimation techniques were also emphasized as were the current debates about stochastic and deterministic dynamics, fractal geometry and multifractals, self-organized criticality and multifractal fields, each of which was the subject of a specific general discussion. The conference started with a one day short course of multifractals featuring four lectures on a) Fundamentals of multifractals: dimension, codimensions, codimension formalism, b) Multifractal estimation techniques: (PDMS, DTM), c) Numerical simulations, Generalized Scale Invariance analysis, d) Advanced multifractals, singular statistics, phase transitions, self-organized criticality and Lie cascades (given by D. Schertzer and S. Lovejoy, detailed course notes were sent to participants shortly after the conference). This

    At the 2nd USA Science & Engineering Festival, held in Washington, D. C., from 27 to 29 April, AGU's Education Division (http://education.agu.org/) joined the Centers for Ocean Sciences Education Excellence (COSEE; http://www.cosee.net/) in presenting a series of hands-on activities for children. Titled "Get Your Hands Wet," these activities were developed by COSEE and focused on chemical oceanography, climate change, ocean exploration/measurement, contaminants, physical oceanography, and marine biology. AGU education staff helped to run events such as making sand cards to illustrate the various stages of weathering of rocks and teaching a carbon cycle game, which allowed students to "become" carbon molecules and travel throughout the Earth system. AGU videographer Derek Sollosi captured some of the action at the COSEE/AGU booth on film, along with images of the rest of the festival (seehttp://youtu.be/oX8wPxYZj48). Other popular exhibits included models of NASA rovers, a jet from the U.S. Air Force, and remotely operated vehicles from the National Oceanic and Atmospheric Administration. Celebrities from Mythbusters, The Big Bang Theory, NCIS, and other popular television shows made appearances on stage.

    2012-02-01

    The AGU book imprint, geopress, showcased its expanded activity during events in San Francisco this year. The annual meeting of the AGU Books Board was well attended, underscoring the geopress commitment to transforming the future of its scientific publishing, and the board proposed a number of ideas to enhance AGU's role in informing society about the Earth and space sciences. This year, responding to member feedback, geopress took a new approach to its information sessions and held daily sessions instead of one lunchtime presentation. The result was that more than 3 times as many potential authors and editors explored the opportunity to achieve AGU's goal of informing society about the excitement of Earth and space sciences.

    This project provided travel awards for scientists engaged in research relevant to the DOE mission to participate in the American Geophysical Union (AGU) Chapman Conference on Biogeophysics held October 13-16, 2008, in Portland, Maine (http://www.agu.org/meetings/chapman/2008/fcall/). The objective of this Chapman Conference was to bring together geophysicists, biophysicists, geochemists, geomicrobiologists, and environmental microbiologists that are leaders in their field and have a personal interest in exploring this new interdisciplinary field or are conducting multidisciplinary research with potential impact on biogeophysics in order to define the current state of the science, identify the critical questions facing the community and to generate a roadmap for establishing biogeophysics as a critical subdiscipline of earth science research. The sixty participants were an international group of academics, graduate students and scientists at government laboratories engaged in biogeophysics related research. Scientists from Europe, Israel and China traveled to engage North American colleagues in this highly focused 3.5 day meeting. The group included an approximately equal mix of microbiologists, biogeochemists and near surface geophysicists. The recipients of the DOE travel awards were [1] Dennis Bazylinski (University of Nevada, Las Vegas), [2] Yuri Gorby (Craig Venter Institute), [3] Carlos Santamarina (Georgia Tech), [4] Susan Hubbard (Lawrence Berkeley Laboratory), [5] Roelof Versteeg (Idaho National Laboratory), [6] Eric Roden (University of Wisconsin), [7] George Luther (University of Delaware), and [8] Jinsong Chen (Lawrence Berkeley Laboratory)

    Dairy industry fermentative processes mostly use Lactococcus lactis as a starter. However, some dairy L. lactis strains produce putrescine, a biogenic amine that raises food safety and spoilage concerns, via the agmatine deiminase (AGDI) pathway. The enzymatic activities responsible for putrescine biosynthesis in this bacterium are encoded by the AGDI gene cluster. The role of the catabolic genes aguB, aguD, aguA, and aguC has been studied, but knowledge regarding the role of aguR (the first gene in the cluster) remains limited. In the present work, aguR was found to be a very low level constitutively expressed gene that is essential for putrescine biosynthesis and is transcribed independently of the polycistronic mRNA encoding the catabolic genes (aguBDAC). In response to agmatine, AguR acts as a transcriptional activator of the aguB promoter (PaguB), which drives the transcription of the aguBDAC operon. Inverted sequences required for PaguB activity were identified by deletion analysis. Further work indicated that AguR is a transmembrane protein which might function as a one-component signal transduction system that senses the agmatine concentration of the medium and, accordingly, regulates the transcription of the aguBDAC operon through a C-terminal cytoplasmic DNA-binding domain typically found in LuxR-like proteins.

    Hall, F. R.; Johnson, R.

    2002-12-01

    In 2002, the Subcommittee on Diversity (SD) of the Committee on Education and Human Resources (CEHR) submitted a Diversity Plan to the leadership of AGU. This plan outlines specific programs and goals that AGU can follow to help improve diversity in the Earth and space sciences. Diversity issues are key components to improve the human resource potential in the geosciences. As women are the majority population, and racial and ethnic minorities are experiencing the largest growing segment of the United States population, it is within our best interest to actively recruit and retain these populations into our dynamic fields of study. The SD recognizes that the strength of the AGU lies within its membership. Composed of some of the brightest and talented scientists in the world, the AGU members are leaders and pioneers in our understanding of the Earth System. Yet, many, if not most, people within underrepresented communities are not aware of the relevance that the Earth and space sciences play in their lives. In this discussion, we will discuss the importance of the AGU membership in the Diversity Plan. In addition, we will outline specific things that AGU members can do to improve access of US students and citizenry to Earth and space science education. These steps require that AGU members become active advocates in the public, especially at the K-14 level.

    Climate change, earthquake preparedness, rare earth elements, hydraulic fracking, and America's global competitiveness in science are among the science topics in policy headlines today. For legislators to create good policy on these and other topics related to the Earth and space sciences, they need access to good science, which is why AGU encourages its members to participate in Congressional Visits Days. On 21-22 September, 55 Earth and space scientists from 24 states brought their expertise to the U.S. Congress, in Washington, D. C., for the third annual Geosciences Congressional Visits Day (Geo­CVD). AGU partnered with four other geosciences societies to bring a large scientific presence to Capitol Hill.

    2004-12-01

    The American Geophysical Union (AGU) founded the Diversity Subcommittee in 2000 to address what the AGU felt were important issues for the future of the geoscience community. A recent AGU statement of commitment and concern about issues of diversity reads, in part: It is essential that new strategies for educating, recruiting, and retaining geoscientists from currently under-represented populations be developed (a) for individual investigators seeking students to fill classes or work in their research programs; (b) for institutions looking to replace faculty and researchers; (c) for the larger community looking to the public for continued research funding, and (d) for the future US membership of AGU. In an effort to fulfill its charge, the majority of the 2004-2006 sub-committee's activities will be directed towards: (1) Education of the AGU Membership, including the sub-committee itself, on the salient issues of Diversity; (2) Mentoring and supporting minority students in the pipeline of Earth and Space Science education as well as minority faculty seeking to establish successful collaborations; (3) Establishing a mechanism for quantitative assessment of (a) the AGU demographics, (b) member knowledge, and (c) success of programs in the area of Diversity; (4) Conducting the first ever Chapman Conference on the needs of investigators with disabilities (July, 2005); (5) Partnering with other agencies and societies to build bridges; (6) Creating mechanisms for marketing the Earth and Space sciences to minority audiences; (7) Nurturing of minority members already in the AGU; promoting these members for honors and awards within AGU. Details, goals, and milestones of this program will be presented.

  6. Slightly thermal springs and non-thermal springs at Mount Shasta, California: Chemistry and recharge elevations

    USGS Publications Warehouse

    Nathenson, M.; Thompson, J.M.; White, L.D.

    2003-01-01

    Temperature measurements, isotopic contents, and dissolved constituents are presented for springs at Mount Shasta to understand slightly thermal springs in the Shasta Valley based on the characteristics of non-thermal springs. Non-thermal springs on Mount Shasta are generally cooler than mean annual air temperatures for their elevation. The specific conductance of non-thermal springs increases linearly with discharge temperature. Springs at higher and intermediate elevations on Mount Shasta have fairly limited circulation paths, whereas low-elevation springs have longer paths because of their higher-elevation recharge. Springs in the Shasta Valley are warmer than air temperatures for their elevation and contain significant amounts of chloride and sulfate, constituents often associated with volcanic hydrothermal systems. Data for the Shasta Valley springs generally define mixing trends for dissolved constituents and temperature. The isotopic composition of the Shasta Valley springs indicates that water fell as precipitation at a higher elevation than any of the non-thermal springs. It is possible that the Shasta Valley springs include a component of the outflow from a proposed 210??C hydrothermal system that boils to supply steam for the summit acid-sulfate spring. In order to categorize springs such as those in the Shasta Valley, we introduce the term slightly thermal springs for springs that do not meet the numerical criterion of 10??C above air temperature for thermal springs but have temperatures greater than non-thermal springs in the area and usually also have dissolved constituents normally found in thermal waters. ?? 2002 Elsevier Science B.V.

In this scene, the dunes, and the plain on which the dunes reside, are at least in part covered by a bright carbon dioxide frost. Dark spots indicate areas where the frost has begun to change, either by subliming away to expose dark sand, changing to a coarser particle size, or both. The winds responsible for the formation of these dunes blew from the lower left (southwest) toward the upper right (northeast).

    A lawyer and a scientist walk into a room—but this is no joke. Scientists are facing subpoenas, Freedom of Information Act (FOIA) requests, and other legal issues regarding their scientific work. It is not part of a scientist's traditional training to learn how long to keep emails related to federally funded research or what to do if their research is subpoenaed. To assist members dealing with these matters AGU partnered, in 2013, with the Climate Science Legal Defense Fund (CSLDF) for a second year to put on the Legal Education for Scientists program, a series of events aimed at helping them navigate these often murky legal waters.

  10. Variable stiffness torsion springs

    NASA Technical Reports Server (NTRS)

    Alhorn, Dean C. (Inventor); Polites, Michael E. (Inventor)

    1994-01-01

    In a torsion spring the spring action is a result of the relationships between the torque applied in twisting the spring, the angle through which the torsion spring twists, and the modulus of elasticity of the spring material in shear. Torsion springs employed industrially have been strips, rods, or bars, generally termed shafts, capabable of being flexed by twisting their axes. They rely on the variations in shearing forces to furnish an internal restoring torque. In the torsion springs herein the restoring torque is external and therefore independent of the shearing modulus of elasticity of the torsion spring shaft. Also provided herein is a variable stiffness torsion spring. This torsion spring can be so adjusted as to have a given spring constant. Such variable stiffness torsion springs are extremely useful in gimballed payloads such as sensors, telescopes, and electronic devices on such platforms as a space shuttle or a space station.

    The Education and Human Resources Committee reported having approved participation in the Association for Women Geoscientist's (AWG) national survey. During the summer of 1983 the AWG designed a 75-question survey targeted to women but also applicable to men. The survey consisted of five sections (in addition to such demographics as age, salary, education, job area, and society membership): feelings and attitude toward job, career/family balance, sexual harassment and discrimination, opinions on national energy and conservation policy, and attitude toward AWG. The questionnaire was mailed to AWG members (just over 1000) and to AGU female members (about 1300). Survey participants were asked to give copies to their male colleagues to create a comparison group. About 25% of the 800 responses were from men. The responses were split about 50/50 between AWG and AGU members. The Education and Human Resources Committee will have the results from the survey presented at their next meeting in Cincinnati, May 15.

    The AGU statement on the investigation of Italian scientists and officials in regard to the L'Aquila earthquake (Eos, 91(28), 248, 13 July 2010) appears to be a noble attempt to protect not only these individuals but also those AGU members who are involved in similar hazard and risk assessments. But in the long run this statement not only damages AGU by misleading its membership as to the responsibilities of the indicted individuals but also sends the wrong message to the Italian scientific communities about their social responsibilities. The AGU statement assumes that the indicted individuals are innocent because it is not possible for scientists to predict earthquakes, but it neglects to explain what their scientific responsibilities are and why these individuals may be also guilty of failing to properly exercise their social responsibility. If one accepts public funds, has the responsibility of deciding how to manage those funds, and is playing the double role of a scientist and a politician, one is also responsible for both the scientific and social consequences of one's actions. Because some of the indicted individuals are also responsible for drafting and promoting the unreliable Vesuvius Evacuation Plan (http://www.westnet.com/˜dobran), they should also be accountable for the consequences in the Vesuvius area.

    A program entitled “Carbon Capture and Storage (CCS)—Viable technology or risky gamble?” was the inaugural event of AGU's Embassy Lecture Series and part of the European Embassy Science Series. With many countries looking into ways to reduce carbon dioxide emissions, the 9 September event at the Germany Embassy in Washington, D. C., focused on the technological and commercial feasibility of CCS. Four speakers addressed questions including whether CCS can be implemented successfully on a commercial scale and if the technology is economically feasible with or without a cap and trade system, and whether the public will support CCS. They stressed the importance of good science, proper planning, and sound monitoring to ensure that the carbon captured will be stored permanently.

    2012-05-01

    Though the lure of rocks, minerals, and radioactive elements took her away from her original studies, one geology Ph.D. candidate is returning to her journalism roots this summer as AGU's 2012 Mass Media Science and Engineering Fellow. Jessica Morrison is one of 12 young scientists nationwide who are trading in their lab coats for reporters' notebooks in mid-June as part of the program coordinated by the American Association for the Advancement of Science, which helps young scientists cultivate communication skills to help disseminate scientific information to general audiences. Morrison is a Ph.D. student in the Department of Civil Engineering and Geological Sciences at the University of Notre Dame. She spends her days in a laboratory investigating the geochemistry of actinides, the radioactive elements in the "no man's land" of the periodic table—the section that often gets left off or moved to the bottom. These are elements like uranium, neptunium, and plutonium.

    1977-01-01

    The first comprehensive report of Florida's springs, which contains both a story of the springs and a collection of facts about them, was published thirty years ago (Ferguson and others, 1947). Since then, much additional data on springs have been gathered and the current report, Springs of Florida, makes a wealth of information on springs available to the public. Springs of Florida, prepared by the U.S. Geological Survey in cooperation with the Bureau of Geology, Florida Department of Natural Resources, publishers, and the Bureau of Water Resources Management, Florida Department of Environmental Regulation, is intended to provide sufficient background information for a lucid understanding of the nature and occurrence of the springs in the State.

    2012-03-01

    Students at 2-year colleges are a critical part of the future Earth and space science workforce, and undergraduate research experiences provide a hook to retain and ultimately to graduate students in the field. AGU was awarded a planning grant by the U.S. National Science Foundation Directorate for Geosciences (Opportunities for Enhancing Diversity in the Geosciences award 1201578) to help launch a new initiative concerning these issues; education and public outreach staff are the principal investigators. This new initiative, titled Unique Research Experiences for Two-Year College Faculty and Students (URECAS), will begin with a planning workshop this summer (11-13 July). The workshop will bring together faculty from 2-year colleges, 4-year colleges and universities, and representatives from professional societies and federal organizations to learn more about how to support 2-year-college faculty and students engaged in Earth and space science research and to discuss the development of a program to strengthen the role of 2-year-college Earth and space science students in the future workforce

    A simple venting device for trapped gas pockets in hydraulic systems is inserted through a small access passages, operated remotely, and removed completely. The device comprises a small diameter, closely wound coil spring which is pushed through a guide temporarily inserted in the access passage. The guide has a central passageway which directs the coil spring radially upward into the pocket, so that, with the guide properly positioned for depth and properly oriented, the coil spring can be pushed up into the top of the pocket to vent it. By positioning a seal around the free end of the guide, the spring and guide are removed and the passage is sealed.

    Moore, L.

    1986-07-29

    This patent describes an engine having a valve guide operatively mounting a valve stem and its associated valve spring and spring retainer for actuation of the valve stem by a valve actuator. An improvement is described comprising: a hollow, generally cylindrical shaped skirt means having a side portion forming an interior with one open end and having at its other end an end portion extending inwardly and formed with an axial opening therein communicating to the interior. The skirt means is mounted on and about the valve stem and spring retainer and about its spring so as to move with the valve stem and to cover the spring retainer and most of the portion of the valve spring and the valve stem extending outwardly from the valve guide except for an outermost end of the stem which extends through the opening in the end portion for actuation by the actuator , such that the inwardly extending end portion lies between the outermost end of the stem and an outermost end of the spring retainer to allow for retrofitting insertion of the skirt means over existing valve stems without removal of the spring and spring retainer. Excessive oil is presented from seeping between and valve guide and the valve stem thus preventing excessive carbon build-up in the combustion area, sticking valves, fouled plugs and high exhaust emissions.

    NASA Technical Reports Server (NTRS)

    1990-01-01

    The 1990 Western Pacific Geophysics Meeting was held in Kanazawa, Japan from 15-21 Aug. 1990. This was the first meeting of a new series of meetings for the American Geophysical Union, and it proved to be very successful in terms of the scientific program and attendance, which included over 1,000 participants. The intent of this meeting was an effort on the part of the American Geophysical Union (AGU) and several Japanese geophysical societies to gather individual Earth and space scientists at a major scientific meeting to focus on geophysical problems being studied in the western Pacific rim. The meeting was organized along the lines of a typical AGU annual meeting with some invited talks, many contributed talks, poster sessions, and with emphasis on presentations and informal discussions. The program committee consisted of scientists from both the U.S. and Japan. This meeting provided ample opportunities for U.S. and Japanese scientists to get to know each other and their works on a one-to-one basis. It was also a valuable opportunity for students studying geophysics to get together and interact with each other and with scientists from both the U.S. and Japan. There were 939 abstracts submitted to the conference and a total of 102 sessions designed as a result of the abstracts received. The topics of interest are as follows: space geodetic and observatory measurements for earthquake and tectonic studies; gravity, sea level, and vertical motion; variations in earth rotation and earth dynamics; sedimentary magnetism; global processes and precipitation; subsurface contaminant transport; U.S. Western Pacific Rim initiatives in hydrology; shelf and coastal circulation; tectonics, magmatism, and hydrothermal processes; earthquake prediction and hazard assessment; seismic wave propagation in realistic media; and dynamics and structure of plate boundaries and of the Earth's deep interior.

    Test equipment is described that includes a system of three quartz indicators whereby three different pressures could be synchronized and simultaneously recorded on a single oscillogram. This equipment was used to test the reliction of waves at ends of valve spring, the dynamical stress of the valve spring for a single lift of the valve, and measurement of the curve of the cam tested. Other tests included simultaneous recording of the stress at both ends of the spring, spring oscillation during a single lift as a function of speed, computation of amplitude of oscillation for a single lift by harmonic analysis, effect of cam profile, the setting up of resonance, and forced spring oscillation with damping.

  13. Rotary spring energy storage

    SciTech Connect

    Cooley, S.

    1981-07-01

    The goal was to design a lightweight system, for bicycles, that can level the input energy requirement (human exertion) in accordance with variations in road load (friction, wind, and grade) and/or to provide a system for regenerative braking, that is, to store energy normally lost in brake pad friction for brief periods until it required for re-acceleration or hill-climbing. The rotary spring, also called the coil, motor, spiral, or power spring is governed by the equations reviewed. Materials used in spring manufacture are briefly discussed, and justification for steel as the design choice of material is given. Torque and power requirements for a bicycle and rider are provided as well as estimated human power output levels. These criteria are examined to define spring size and possible orientations on a bicycle. Patents and designs for coupling the spring to the drive train are discussed.

  16. Expression of the agmatine deiminase pathway in Enterococcus faecalis is activated by the AguR regulator and repressed by CcpA and PTS(Man) systems.

    Although the agmatine deiminase system (AgDI) has been investigated in Enterococcus faecalis, little information is available with respect to its gene regulation. In this study we demonstrate that the presence of exogenous agmatine induces the expression of agu genes in this bacterium. In contrast to the homologous and extensively characterized AgDI system of S. mutants, the aguBDAC operon in E. faecalis is not induced in response to low pH. In spite of this, agmatine catabolism in this bacterium contributes by neutralizing the external medium while enhancing bacterial growth. Our results indicate that carbon catabolic repression (CCR) operates on the AgDI system via a mechanism that involves interaction of CcpA and P-Ser-HPr with a cre site found in an unusual position considering the aguB promoter (55 nt upstream the +1 position). In addition, we found that components of the mannose phosphotransferase (PTS(Man)) system also contributed to CCR in E. faecalis since a complete relief of the PTS-sugars repressive effect was observed only in a PTS(Man) and CcpA double defective strain. Our gene context analysis revealed that aguR is present in oral and gastrointestinal microorganisms. Thus, regulation of the aguBDAC operon in E. faecalis seems to have evolved to obtain energy and resist low pH conditions in order to persist and colonize gastrointestinal niches. PMID:24155893

  20. [Comment on “Looking at gender distribution among AGU Fellows”] An open letter to Ellen Druffel

    NASA Astrophysics Data System (ADS)

    Russell, C. T.

    I would like to congratulate you on your excellent study of the gender distribution of AGU Fellows [Eos, Sept. 13, 1994]. However, I must take issue with your interpretation of some of the data. First of all you concentrate on the inequity in the awarding of AGU Fellowships. I, on the other hand, look at Figure 3 with amazement that, considering the obstacles in women's careers, the ratios are as good as they are. If you added only one 80-year-old woman, two 70-year-old women, two 60-year-olds and four 50-year-olds, the curves would look almost identical. Surely, it would be possible this year to elect 9 women to Fellowship out of the 30 Fellows to be elected. This change seems possible especially in sections like GP and Hydrology that clearly have a surplus of good female candidates, since none have been elected for some time. I think that the deficit can quickly be eliminated with just a modicum of attention to identifying the previously overlooked candidates and securing nominations for them. The following is some advice on the process, based on my nomination of two female candidate Fellows, one of whom was successful and one of whom thus far has not been successful.

    Public places such as parks, urban plazas, transportation centers and educational institutions offer the opportunity to reach many people in the course of daily life. Yet these public spaces are often devoid of any substantive information about the local environment and natural processes that have shaped it. Art is a particularly effective means to visualize environmental phenomena. Art has the ability to translate the processes of nature into visual information that communicates with clarity and beauty. People often have no connection to the world through which they walk: no sense of their place in the local watershed or where the rainwater goes once it hits the ground. Creating an awareness of place is critical first step for people to understand the changes in their world. Art can be a gateway for understanding geo-scientific concepts that are not frequently made accessible in a visual manner And art requires scientific knowledge to inform an accurate visualization of nature. Artists must collaborate with scientists in order to create art that informs the public about environmental processes. There is a new current in the design world that combines art and technology to create artful solutions to site issues such as storm water runoff, periodic flooding and habitat destruction. Instead of being considered functionless, art is now given a chance to do some real work on the site. This new combination of function and aesthetic concerns will have a major impact on how site issues are perceived. Site concerns that were once considered obstacles can become opportunities to visualize and celebrate how problems can be solved. This sort of artful solutions requires teamwork across many disciplines. In my presentation I will speak about various ways of I have visualized the invisible processes of the natural world in my projects. I will share eight of my permanent and temporary art commissions that are collaborations with scientists and engineers. These works reveal wetland habitats, tides, prevailing winds, rain and microorganisms, and water pollution. In examining each project I will detail the essential collaborations with scientists and engineers that brought the projects to fruition. I will discuss how the cross-discipline approach of scientists, engineers and designers made effective and artful solutions to site issues, and created visually stimulating and educational places. I will also look at the role of truth and metaphor in art and compare how accuracy and data collection have differing thresholds in art and in science.

  4. Walking with springs

    NASA Astrophysics Data System (ADS)

    Sugar, Thomas G.; Hollander, Kevin W.; Hitt, Joseph K.

    2011-04-01

    Developing bionic ankles poses great challenges due to the large moment, power, and energy that are required at the ankle. Researchers have added springs in series with a motor to reduce the peak power and energy requirements of a robotic ankle. We developed a "robotic tendon" that reduces the peak power by altering the required motor speed. By changing the required speed, the spring acts as a "load variable transmission." If a simple motor/gearbox solution is used, one walking step would require 38.8J and a peak motor power of 257 W. Using an optimized robotic tendon, the energy required is 21.2 J and the peak motor power is reduced to 96.6 W. We show that adding a passive spring in parallel with the robotic tendon reduces peak loads but the power and energy increase. Adding a passive spring in series with the robotic tendon reduces the energy requirements. We have built a prosthetic ankle SPARKy, Spring Ankle with Regenerative Kinetics, that allows a user to walk forwards, backwards, ascend and descend stairs, walk up and down slopes as well as jog.

  5. Spring polar ozone behavior

    1992-01-01

    Understanding of the springtime behavior of polar stratospheric ozone as of mid 1990 is summarized. Heterogeneous reactions on polar stratospheric clouds as hypothesis for ozone loss are considered and a simplified description of the behavior of Antarctic ozone in winter and spring is given. Evidence that the situation is more complicated than described by the theory is produced. Many unresolved scientific issues remain and some of the most important problems are identified. Ozone changes each spring since 1979 have clearly established for the first time that man made chlorine compounds influence stratospheric ozone. Long before important advances in satellite and in situ investigations, it was Dobson's decision to place a total ozone measuring spectrometer at Halley Bay in Antarctica during the International Geophysical Year and subsequent continuous monitoring which led to the discovery that ozone was being destroyed each spring by chlorine processed by polar stratospheric clouds.

The confession had nothing to do with what he called the “preposterous premises” of the movie, including that humans could start or stop the spinning of Earth's core. Rather, he told the crowd at the Tuesday evening presentation “Science and the Cinema: AGU Sciences Meet Hollywood” about his recurring dream of being on stage wearing nothing but a skimpy T-shirt. “This dream now has come true. Here I am, I'm talking to a whole room of geophysicists about The Core. I've never felt like the T-shirt was this short,” he said.

  17. AGU Statement: Investigation of Scientists and Officials in L'Aquila, Italy, Is Unfounded

    NASA Astrophysics Data System (ADS)

    2010-07-01

    Seven Italian scientists and government officials are under investigation on charges of manslaughter for failure to warn the city of L'Aquila, Italy, before an earthquake hit last year, killing hundreds. The six seismologists and one government official under investigation, who are employees of the National Institute for Geophysics and Volcanology (INGV) and the Civil Protection Department, took part in a meeting of the Major Risks Committee on 31 March 2009. At the meeting, the committee told L'Aquila city officials that “just because a small series of quakes has been observed [in L'Aquila] there is no reason to suggest that the sequence of low-magnitude tremors are a precursor to a major event,” which was deemed “improbable, although not impossible.” However, on 6 April 2009, the city was struck by a Mw 6.3 earthquake that killed 308 people.

  19. Hot Spring Metagenomics

    PubMed Central

    López-López, Olalla; Cerdán, María Esperanza; González-Siso, María Isabel

    2013-01-01

    Hot springs have been investigated since the XIX century, but isolation and examination of their thermophilic microbial inhabitants did not start until the 1950s. Many thermophilic microorganisms and their viruses have since been discovered, although the real complexity of thermal communities was envisaged when research based on PCR amplification of the 16S rRNA genes arose. Thereafter, the possibility of cloning and sequencing the total environmental DNA, defined as metagenome, and the study of the genes rescued in the metagenomic libraries and assemblies made it possible to gain a more comprehensive understanding of microbial communities—their diversity, structure, the interactions existing between their components, and the factors shaping the nature of these communities. In the last decade, hot springs have been a source of thermophilic enzymes of industrial interest, encouraging further study of the poorly understood diversity of microbial life in these habitats.

    Riby, Leigh M

    2013-01-01

    This study used Vivaldi's Four Seasons, an extraordinary example of program music, to explore the consequence of music exposure on cognitive event-related potentials (ERPs). Seventeen participants performed a three-stimulus visual odd-ball task while ERPs were recorded. Participants were required to differentiate between a rare target stimulus (to elicit a memory updating component; P3b), a rare novel stimulus (to elicit a novelty attention component; P3a), and a frequent nontarget stimulus. During task performance participants listened to the four concertos: Spring, Summer, Autumn, and Winter in comparison to a silent control condition. Additionally, the three movements of each concerto have a fast, slow, fast structure that enabled examination of the impact of tempo. The data revealed that "Spring," particularly the well-recognized, vibrant, emotive, and uplifting first movement, had the ability to enhance mental alertness and brain measures of attention and memory.

  1. Spring operated accelerator and constant force spring mechanism therefor

    NASA Technical Reports Server (NTRS)

    Shillinger, G. L., Jr. (Inventor)

    1977-01-01

    A spring assembly consisting of an elongate piece of flat spring material formed into a spiral configuration and a free running spool in circumscribing relation to which this spring is disposed was developed. The spring has a distal end that is externally accessible so that when the distal end is drawn along a path, the spring unwinds against a restoring force present in the portion of the spring that resides in a transition region between a relatively straight condition on the path and a fully wound condition on the spool. When the distal end is released, the distal end is accelerated toward the spool by the force existing at the transition region which force is proportional to the cross-sectional area of the spring.

    1999-03-29

    The properties of exchange-spring-coupled bilayer and superlattice films are highlighted for Sm-Co hard magnet and Fe or Co soft magnet layers. The hexagonal Sm-Co is grown via magnetron sputtering in a- and b-axis epitaxial orientations. In both cases the c-axis, in the film plane, is the easy axis of magnetization. Trends in coercivity with film thickness are established and related to the respective microstructure of the two orientations. The magnetization reversal process for the bilayers is examined by magnetometry and magneto-optical imaging, as well as by simulations that utilize a one-dimensional model to provide the spin configuration for each atomic layer. The Fe magnetization is pinned to that of the Sm-Co at the interface, and reversal proceeds via a progressive twisting of the Fe magnetization. The Fe demagnetization curves are reversible as expected for a spring magnet. Comparison of experiment and simulations indicates that the spring magnet behavior can be understood from the intrinsic properties of the hard and soft layers. Estimated are made of the ultimate gain in performance that can potentially be realized in this system.

    Simple measurements on car suspension systems and their analysis can raise student interest in the elementary discussion of the behavior of springs in oscillating systems. To understand these complicated oscillating systems and to interpret measurements properly, models may be used. Students find out how to make approximations and extract useful information from marginal data using common sense, basic physics, and simple software tools. Basic experiments on a physical model of a car suspension and on a passenger car, as well as the analysis of the data, will be presented. In particular, a value of the bounce mode frequency of a car was obtained using several approaches.

  8. Job center

    NASA Astrophysics Data System (ADS)

    To better meet the needs of AGU members, a program has been started to increase the effectiveness of the Job Center activity at the Spring and Fall Meetings. As a result, participation in the Job Center at the 1988 AGU Spring Meeting in Baltimore increased substantially compared to previous Spring Meetings. The number of employers, applicants, and interviews scheduled more than doubled compared to the 1987 Spring Job Center.In order to make the meeting Job Centers even better, a survey is being conducted of employers and applicants who participated in the 1988 Spring Job Center. Evaluation of this survey will be useful in continuing increased participation in and the effectiveness of the Job Center at the 1988 Fall Meeting. Past participants and those interested in the future of the Job Center are encouraged to forward comments and suggestions to AGU, Member Programs Division, 2000 Florida Ave., N.W., Washington, DC 20009.

    wells far from the spring, the efficiency of the whole system can be optimized in terms of total withdrawal, drilling and management costs, with reduced environmental impact. The mathematical model also shows how long the system takes to regain its "undisturbed" state, with a tolerance of 0.5 l/s. The model highlights the possibility of forcing the system to supply a smaller amount of water in winter, in order to increase the summer yield. Such a management scheme, which can be applied to other springs, may be useful in better meeting the demand for water during dry seasons.

    2014-12-01

    The International Glaciological Society was founded in 1936 to provide a focus for individuals interested in practical and scientific aspects of snow and ice. The objects of the Society enshrined in its Constitution are to stimulate interest in and encourage research into the scientific and technical problems of snow and ice in all countries and to facilitate and increase the flow of glaciological ideas and information through publishing the Journal of Glaciology, the Annals of Glaciology, ICE, the News Bulletin of the International Glaciological Society and other appropriate publications, such as books and monographs and also sponsored lectures, field meetings and symposia. After 78 years the Society is entering a new phase to adapt to the new ways of publishing scientific work. The days of the printed word are all but over with the advent of the internet. Learned publishers are modifying their procedures, sometime a difficult thing to do when you have decades of traditions to live up to, such as an award for 'Best Learned Journal' as recently as 2007. All this has to be factored in when making the transition.

  20. BLACKJACK SPRINGS WILDERNESS, WISCONSIN.

    USGS Publications Warehouse

    Schulz, Klaus J.

    1984-01-01

    The mineral-resource potential of the Blackjack Springs Wilderness in northern Wisconsin was evaluated. The lack of bedrock exposures in or near the wilderness and the thick mantle of glacial sediments precludes a detailed assessment of the mineral potential of the wilderness. However, based on presently available data, the area is concluded to offer little promise for the occurrence of mineral resources. If mineral deposits exist in the area, they would be under thick glacial cover and probably be of the massive sulfide type in association with metavolcanic rocks or be magmatic copper-nickel in association with metamorphosed mafic intrusive rocks. Sand and gravel resources occur in the wilderness, but they are abundant regionally, outside the wilderness. No other metallic or energy resources were identified in this study.

    1996-03-01

    Because of its copious and reliable rainfall, Ireland has an abundance of springs. Many of the larger ones issue from the Carboniferous limestone that occurs in over 40% of the country. The spring water is mainly a calcium bicarbonate type with a temperature of about 10°C. In the 18th century, warm and cold springs were developed as spas in various parts of Ireland. The popularity of these springs was short and most were in major decline by 1850. Today only one cold spa at Lisdoonvarna, Co. Clare is still operating. Springs in Ireland were places of religious significance for the pre-Christian Druidic religion. In the Christian period they became holy wells, under the patronage of various saints. Cures for many different ailments were attributed to water from these wells.

  17. Linear magnetic spring and spring/motor combination

    NASA Technical Reports Server (NTRS)

    Patt, Paul J. (Inventor); Stolfi, Fred R. (Inventor)

    1991-01-01

    A magnetic spring, or a spring and motor combination, providing a linear spring force characteristic in each direction from a neutral position, in which the spring action may occur for any desired coordinate of a typical orthogonal coordinate system. A set of magnets are disposed, preferably symmetrically about a coordinate axis, poled orthogonally to the desired force direction. A second set of magnets, respectively poled opposite the first set, are arranged on the sprung article. The magnets of one of the sets are spaced a greater distance apart than those of the other, such that an end magnet from each set forms a pair having preferably planar faces parallel to the direction of spring force, the faces being offset so that in a neutral position the outer edge of the closer spaced magnet set is aligned with the inner edge of the greater spaced magnet set. For use as a motor, a coil can be arranged with conductors orthogonal to both the magnet pole directions and the direction of desired spring force, located across from the magnets of one set and fixed with respect to the magnets of the other set. In a cylindrical coordinate system having axial spring force, the magnets are radially poled and motor coils are concentric with the cylinder axis.

    Samodovitz, A. J.

    1985-12-10

    The invention is an improved piston engine, either two stroke or four stroke. In one, two stroke, one cylinder embodiment, the improvement comprises two springs connecting between the piston and the base of the piston. These springs are relatively relaxed when the crank is at top dead center. Then during the power/intake stroke, some of the fuel's energy is delivered to the crankshaft and some is used to compress the springs. The stored energy in the springs is delivered to the crankshaft during the exhaust/compression stroke while the springs return to their relatively relaxed condition. As a result, energy is delivered to the crankshaft during both strokes of the cycle, and the engine runs smooth. In one, four stroke, two cylinder embodiment, each cylinder has springs as described above, the cranks of each cylinder are aligned, and the cam sets one cylinder in the power stroke while the other is in the intake stroke. As a result, the engine runs smooth because energy is delivered to the crankshaft during all four strokes of the cycle, during two of the strokes by the burning fuel and during the other two by the release of energy in the springs. In both embodiments, a heavy crankshaft is not needed because of the more uniform power delivery.

    Spring Creek Springs and Wakulla Springs are large first magnitude springs that derive water from the Upper Floridan Aquifer. The submarine Spring Creek Springs are located in a marine estuary and Wakulla Springs are located 18 km inland. Wakulla Springs has had a consistent increase in flow from the 1930s to the present. This increase is probably due to the rising sea level, which puts additional pressure head on the submarine Spring Creek Springs, reducing its fresh water flow and increasing flows in Wakulla Springs. To improve understanding of the complex relations between these springs, flow and salinity data were collected from June 25, 2007 to June 30, 2010. The flow in Spring Creek Springs was most sensitive to rainfall and salt water intrusion, and the flow in Wakulla Springs was most sensitive to rainfall and the flow in Spring Creek Springs. Flows from the springs were found to be connected, and composed of three repeating phases in a karst spring flow cycle: Phase 1 occurred during low rainfall periods and was characterized by salt water backflow into the Spring Creek Springs caves. The higher density salt water blocked fresh water flow and resulted in a higher equivalent fresh water head in Spring Creek Springs than in Wakulla Springs. The blocked fresh water was diverted to Wakulla Springs, approximately doubling its flow. Phase 2 occurred when heavy rainfall resulted in temporarily high creek flows to nearby sinkholes that purged the salt water from the Spring Creek Springs caves. Phase 3 occurred after streams returned to base flow. The Spring Creek Springs caves retained a lower equivalent fresh water head than Wakulla Springs, causing them to flow large amounts of fresh water while Wakulla Springs flow was reduced by about half.

  4. Hydrogeology of the mineral springs at Manitou Springs, Colorado

    1985-01-01

    Manitou Springs, a small resort community located at the base of 14,110 foot Pikes Peak, is situated at the south end of the southward plunging Williams Canyon Anticline. This is truncated south of town by the Ute Pass Reverse Fault, with over 30,000 feet of displacement. Paleozoic limestones are exposed north of Manitou Springs in north-south trending Williams Canyon. The Mississippian age Leadville Limestone and underlying Ordovician age Manitou Limestone contain over 40 caves, including the 8500-foot long Cave of the Winds system. These limestones continue under Manitou Springs, where cave forming processes have resulted in water-filled caverns. The 28 natural springs and flowing wells in Manitou Springs source in the limestone caverns. This carbonate aquifer is bounded by the Ute Pass Fault on the west and southwest, the Rampart Range Fault to the east, and open to recharge from exposed limestone to the north. Areal extent of the aquifer is approximately 3.5 spare miles, containing an estimated 10 billion gallons. In the past 100 years, spring development has lowered the potentiometric surface 50 feet. Contemporary and historical chemical analyses of the mineral water show high concentrations of calcium, magnesium, bicarbonate, and carbon dioxide gas. This suggests prolonged exposure of the water to limestone, as confirmed by Carbon 14 age-dating values of up to 30,000 years.

    In July 2004, the Department of Energy (DOE) allocated funds in support of the development of A Data Exchange Format for Biological Pathway Databases (BioPAX). The primary objective of the BioPAX initiative is the development of a standard data exchange format for biological pathway data. This standard will significantly ease the analysis of biological pathways in the life sciences. Support from the DOE has enabled BioPAX to make significant progress towards its objective. We were able to build a very active community of pathway data and software tool providers. Work is continuing on the BioPAX standard with meetings, input and feedback provided for Level 3 of the standard and beyond.

    Shales are a component of the terrestrial subsurface biosphere and may be colonized by microorganisms when temperature and fluid flow are permitting. Assessing microbial community activity will be aided by the use of in situ sampling devices such as the osmosampler, an osmotically driven sampling device. Community analysis of shale samples remains a challenge and requires further methods development. The objectives of the work reported are: 1. to review geochemical and microbiological evidence for the possible microbial inhabitation of shale 2. to compare conditions among U.S. shale formations 3. to develop analytical techniques to evaluate microbial communities present in hydraulic fracturing fluid.

  13. Fossilization Processes in Thermal Springs

    Farmer, Jack D.; Cady, Sherry; Desmarais, David J.; Chang, Sherwood (Technical Monitor)

    1995-01-01

    To create a comparative framework for the study of ancient examples, we have been carrying out parallel studies of the microbial biosedimentology, taphonomy and geochemistry of modem and sub-Recent thermal spring deposits. One goal of the research is the development of integrated litho- and taphofacies models for siliceous and travertline sinters. Thermal springs are regarded as important environments for the origin and early evolution of life on Earth, and we seek to utilize information from the fossil record to reconstruct the evolution of high temperature ecosystems. Microbial contributions to the fabric of thermal spring sinters occur when population growth rates keep pace with, or exceed rates of inorganic precipitation, allowing for the development of continuous biofilms or mats. In siliceous thermal springs, microorganisms are typically entombed while viable. Modes of preservation reflect the balance between rates of organic matter degradation, silica precipitation and secondary infilling. Subaerial sinters are initially quite porous and permeable and at temperatures higher than about 20 C, organic materials are usually degraded prior to secondary infilling of sinter frameworks. Thus, organically-preserved microfossils are rare and fossil information consists of characteristic biofabrics formed by the encrustation and underplating of microbial mat surfaces. This probably accounts for the typically low total organic carbon values observed in thermal spring deposits. In mid-temperature, (approx. 35 - 59 C) ponds and outflows, the surface morphology of tufted Phormidium mats is preserved through mat underplating by thin siliceous: crusts. Microbial taxes lead to clumping of ceils and/or preferred filament orientations that together define higher order composite fabrics in thermal spring stromatolites (e.g. network, coniform, and palisade). At lower temperatures (less than 35 C), Calothrix mats cover shallow terracette pools forming flat carpets or pustular

    . The mat also contained abundant n,n-wax esters of C32 to C37, characteristic of Chloroflexus. 10-Methyl-C16 was also detected, indicative of sulfate reducing bacteria (SRB). The narrow Oscillatoria mat was dominated by the aforementioned cyanobacterial biomarkers as well as iso-C17:1, a biomarker for some groups of SRB. Unusual dimethyl fatty acids were also detected. The goal of this research is to provide an initial dataset that will illustrate the maximum amount of paleobiological and paleoenvironmental information expected to form in these types of iron deposits. Insights from our research may help elucidate the role of phototrophs in the deposition of BIFs on Earth, and may assist in the search for evidence of fossilized microbial life in iron deposits on Mars.

    The failure of rectangular clutch spring of automatic slack adjuster directly affects the work of automatic slack adjuster. We establish the structural mechanics model of automatic slack adjuster rectangular clutch spring based on its working principle and mechanical structure. In addition, we upload such structural mechanics model to ANSYS Workbench FEA system to predict the fatigue life of rectangular clutch spring. FEA results show that the fatigue life of rectangular clutch spring is 2.0403×105 cycle under the effect of braking loads. In the meantime, fatigue tests of 20 automatic slack adjusters are carried out on the fatigue test bench to verify the conclusion of the structural mechanics model. The experimental results show that the mean fatigue life of rectangular clutch spring is 1.9101×105, which meets the results based on the finite element analysis using ANSYS Workbench FEA system.

  17. Motor gasoline assessment, Spring 1997

    SciTech Connect

    1997-07-01

    The springs of 1996 and 1997 provide an excellent example of contrasting gasoline market dynamics. In spring 1996, tightening crude oil markets pushed up gasoline prices sharply, adding to the normal seasonal gasoline price increases; however, in spring 1997, crude oil markets loosened and crude oil prices fell, bringing gasoline prices down. This pattern was followed throughout the country except in California. As a result of its unique reformulated gasoline, California prices began to vary significantly from the rest of the country in 1996 and continued to exhibit distinct variations in 1997. In addition to the price contrasts between 1996 and 1997, changes occurred in the way in which gasoline markets were supplied. Low stocks, high refinery utilizations, and high imports persisted through 1996 into summer 1997, but these factors seem to have had little impact on gasoline price spreads relative to average spread.

    2015-04-19

    The application of aspirin-like drugs in modern medicine is very broad, encompassing the treatment of inflammation, pain and a variety of cardiovascular conditions. Although anecdotal accounts of willow bark extract as an anti-inflammatory drug have occurred since written records began (for example by Hippocrates), the first convincing demonstration of a potent anti-pyretic effect of willow bark containing salicylates was made by the English cleric Edward Stone in the late eighteenth century. Here, we discuss the route to optimizing and understanding the mechanism of action of anti-inflammatory drugs that have their origins in Stone's seminal study, 'An account of the success of the bark of the willow in the cure of agues'. This commentary was written to celebrate the 350th anniversary of the journal Philosophical Transactions of the Royal Society. PMID:25750237

    2015-01-01

    Although alkaline Hunter's Hot Springs in southeastern Oregon has been studied extensively for over 40 years, most of these studies and the subsequent publications were before the advent of molecular methods. However, there are many field observations and laboratory experiments that reveal the major aspects of the phototrophic species composition within various physical and chemical gradients of these springs. Relatively constant temperature boundaries demark the upper boundary of the unicellular cyanobacterium, Synechococcus at 73-74 °C (the world-wide upper limit for photosynthesis), and 68-70 °C the upper limit for Chloroflexus. The upper limit for the cover of the filamentous cyanobacterium, Geitlerinema (Oscillatoria) is at 54-55 °C, and the in situ lower limit at 47-48 °C for all three of these phototrophs due to the upper temperature limit for the grazing ostracod, Thermopsis. The in situ upper limit for the cyanobacteria Pleurocapsa and Calothrix is at ~47-48 °C, which are more grazer-resistant and grazer dependent. All of these demarcations are easily visible in the field. In addition, there is a biosulfide production in some sections of the springs that have a large impact on the microbiology. Most of the temperature and chemical limits have been explained by field and laboratory experiments. PMID:25633225

  4. FOSSIL SPRINGS ROADLESS AREA, ARIZONA.

    USGS Publications Warehouse

    Beard, L.S.; Ellis, C.E.

    1984-01-01

    Based on field studies, the Fossil Springs Roadless Area in central Arizona is concluded to have little promise for the occurrence of mineral or energy resources. Rocks in the Supai Formation (Pennsylvanian-Permian) near the central part of the roadless area contain widespread but spotty copper mineralization and trace amounts of uranium. Analyses obtained during the study define geochemical anomalies in two portions of the area that remain unexplained. The suites of anomalous metals suggest the possibility of hydrothermal veins and the presence of ultramafic rocks; neither were found in the field. Although there is little promise for the occurrence of mineral resources in the Fossil Springs Roadless Area, studies to identify the source of the geochemical anomalies could have valuable implications for regional studies and mineral exploration in the surrounding area.

  5. Force of an actin spring

    NASA Astrophysics Data System (ADS)

    Shin, Jennifer; Mahadevan, L.; Matsudaira, Paul

    2003-03-01

    The acrosomal process of the horseshoe crab sperm is a novel mechanochemical molecular spring that converts its elastic stain energy to mechanical work upon the chemical activation by Ca2+. Twisted and bent, the initial state of the acrosomal bundle features a high degree of complexity in its structure and the energy is believed to be stored in the highly strained actin filaments as an elastic potential energy. When activated, the bundle relaxes from the coil of the highly twisted and bent filaments to its straight conformation at a mean velocity of 15um/s. The mean extension velocity increases dramatically from 3um/s to 27um/s when temperature of the medium is changed from 9.6C to 32C (respective viscosities of 1.25-0.75cp), yet it exhibits a very weak dependence on changes in the medium viscosity (1cp-33cp). These experiments suggest that the uncoiling of the actin spring should be limited not by the viscosity of the medium but by the unlatching events of involved proteins at a molecular level. Unlike the viscosity-limited processes, where force is directly related to the rate of the reaction, a direct measurement is required to obtain the spring force of the acrosomal process. The extending acrosomal bundle is forced to push against a barrier and its elastic buckling response is analyzed to measure the force generated during the uncoiling.

  10. Terrestrial smokers: Thermal springs due to hydrothermal convection of groundwater connected to surface water

    NASA Astrophysics Data System (ADS)

    Bayani Cardenas, M.; Lagmay, Alfredo Mahar F.; Andrews, Benjamin J.; Rodolfo, Raymond S.; Cabria, Hillel B.; Zamora, Peter B.; Lapus, Mark R.

    2012-01-01

    Thermal springs are ubiquitous features whose underground kinematic structure is mostly unknown but are typically thought to originate from deep sources. We documented a type of thermal springs at the banks of a volcanic lake that are discharge zones of hydrothermal convection cells circulating groundwater within the near shore environment. The convection captures lake water through the lakebed, mixes it with deeper groundwater at velocities of 100s of m d-1, then returns the water to the lake via the spring. The convection cell is flushed in a few hours and turns over the lake's volume in a few days. Most volcanic lakes and other relatively cool surface water bodies in areas of elevated geothermal heat fluxes meet the conditions for the occurrence of local hydrothermal circulation of groundwater. The type of spring we studied, the terrestrial version of black smokers, is likely present but perhaps unrecognized at many areas.

  11. Audiomagnetotelluric data from Spring, Cave, and Coyote Spring Valleys, Nevada

    2006-01-01

    Audiomagnetotelluric (AMT) data along four profiles in Spring, Cave, and Coyote Spring Valleys are presented here. The AMT method is used to estimate the electrical resistivity of the earth over depth ranges of a few meters to greater than one kilometer. This method is a valuable tool for revealing subsurface structure and stratigraphy within the Basin and Range of eastern Nevada, therefore helping to define the geohydrologic framework in this region. We collected AMT data using the Geometrics StrataGem EH4 system, a four-channel, natural and controlled- source tensor system recording in the range of 10 to 92,000 Hz. To augment the low signal in the natural field, an unpolarized transmitter comprised of two horizontal-magnetic dipoles was used from 1,000 to 70,000 Hz. Profiles were 1.4 - 12.6 km in length with station spacing of 100-400 m. Data were recorded with the electrical (E) field parallel to and perpendicular to the regional geologic strike direction. Station locations and sounding curves, showing apparent resistivity, phase data, and coherency data, are presented here.

    Geologic, geochemical, and geophysical studies together with a review of historic mining and prospecting activities indicate that the Cactus Spring Roadless Area in California has little promise for the occurrence of mineral or energy resources. Marble bodies occur in the northern part of the roadless area and are possible resources for building stone, crushed and quarried aggregate, and lime and magnesium for Portland cement and industrial applications. It is recommended that the terrane of marble be mapped and sampled carefully in order to evaluate the quantity and quality of the carbonate resources.

  13. Quantum model for entropic springs

    NASA Astrophysics Data System (ADS)

    Wang, Chiao-Hsuan; Taylor, Jacob M.

    2016-06-01

    Motivated by understanding the emergence of thermodynamic restoring forces and oscillations, we develop a quantum-mechanical model of a bath of spins coupled to the elasticity of a material. We show our model reproduces the behavior of a variety of entropic springs while enabling investigation of nonequilibrium resonator states in the quantum domain. We find our model emerges naturally in disordered elastic media, such as glasses, and is an additional expected effect in systems with anomalous specific heat and 1 /f noise at low temperatures due to two-level systems that fluctuate.

    1992-06-01

    Pore waters extracted from sediment cores were analyzed for their oxygen and hydrogen isotopic compositions and major ion chemistry to determine the source of water from a vent area for diffuse lake-bottom thermal springs or seeps in Frolikha Bay, northeastern Lake Baikal. The {delta}{sup 18}O values of pore waters range from {minus}15.2{per thousand} to {minus}16.7{per thousand}, and {delta}D values range from {minus}119{per thousand} to {minus}126{per thousand} (both isotopes determined relative to standard mean ocean water (SMOW)). Bottom water in Lake Baikal has a {delta}{sup 18}O value of {minus}5.6{per thousand} and a {delta}D values of {minus}120{per thousand}. Pore waters in the vent area are significantly enriched in Mg, K, Ca, and especially Na and have the lowest {delta}D and {delta}{sup 18}O values; these pore waters are isotopically and chemically distinct from pore waters in other, more typical parts of the lake. The pore-water isotopic data fall on a local meteoric water line, and covariations in water isotopes and chemistry are not consistent with evaporation or hydrothermal water-rock interaction. The thermal springs represent discharging meteoric waters that have been gently heated during subsurface circulation and are largely unaltered isotopically. Chemical variations are most likely due to dissolution of subsurface evaporites.

    Springs are biodiversity hotspots and unique habitats that are threatened, especially by water overdraft. Here we review knowledge on ambient-temperature (non-geothermal) freshwater springs that achieve sufficient oversaturation for CaCO3 -by physical CO2 degassing and activity of photoautotrophs- to deposit limestone, locally resulting in scenic carbonate structures: Limestone-Precipitating Springs (LPS). The most characteristic organisms in these springs are those that contribute to carbonate precipitation, e.g.: the mosses Palustriella and Eucladium, the crenophilous desmid Oocardium stratum, and cyanobacteria (e.g., Rivularia). These organisms appear to be sensitive to phosphorus pollution. Invertebrate diversity is modest, and highest in pools with an aquatic-terrestrial interface. Internationally, comprehensive legislation for spring protection is still relatively scarce. Where available, it covers all spring types. The situation in Europe is peculiar: the only widespread spring type included in the EU Habitat Directive is LPS, mainly because of landscape aesthetics. To support LPS inventorying and management to meet conservation-legislation requirements we developed a general conceptual model to predict where LPS are more likely to occur. The model is based on the pre-requisites for LPS: an aquifer lithology that enables build-up of high bicarbonate and Ca(2+) to sustain CaCO3 oversaturation after spring emergence, combined with intense groundwater percolation especially along structural discontinuities (e.g., fault zones, joints, schistosity), and a proper hydrogeological structure of the discharging area. We validated this model by means of the LPS information system for the Emilia-Romagna Region (northern Italy). The main threats to LPS are water diversion, nutrient enrichment, and lack of awareness by non-specialized persons and administrators. We discuss an emblematic case study to provide management suggestions. The present review is devoted to LPS but

  4. Dynamics of an actin spring

    NASA Astrophysics Data System (ADS)

    Riera, Christophe; Mahadevan, L.; Shin, Jennifer; Matsudaira, Paul

    2003-03-01

    The acrosome of the sperm of the horseshoe crab (Limulus Polyphemus) is an unusual actin based system that shows a spectacular dynamical transition in the presence of Ca++ that is present in abundance in the neighborhood of the egg. During this process, the bundle, which is initially bent and twisted uncoils and becomes straight in a matter of a few seconds. Based on microstructural data, we propose a model for the dynamics of uncoiling that is best represented by a triple-well potential corresponding to the different structural arrangements of the supertwisted filaments. Each of the false, true and coiled states corresponds to a local minimum of the energy, with the true state being the one with the lowest energy. Using an evolution equation derived by balancing torques, we investigate the nucleation and propagation of the phase transition and compare the results with those of experiments. Our model quantifies the hypothesis that the acrosomal bundle behaves like a mechano-chemical spring.

  6. Modeling and Evaluation of Canted Coil Springs as High Temperature Seal Preloading Devices

    Future reusable launch vehicles will require advanced structural seals. This includes propulsion seals along edges and hinge lines in hypersonic engines, and control surface seals for movable flaps and elevons on proposed reentry vehicles. Seals must remain in sealing engagement with opposing surfaces, for multiple missions, even though the seal gap may be opening and closing due to thermal and structural loads. To meet this requirement either the seals themselves must be resilient or there must be a resilient structural element behind the seals. Case Western Reserve University is working with NASA s Glenn Research Center to develop more resilient high temperature seal components and preloading devices. Results are presented for a finite element analysis of a canted coil spring that is being considered as a high temperature seal preloading device. This type of spring is a leading candidate due to its ability to provide nearly constant force over a large deflection. The finite element analyses were verified by comparing them to experimental results of canted coil springs of three different stiffnesses, measured at Glenn Research Center. Once validated the parameterized model was combined with a scripting algorithm to assess the effects of key spring design variables (wire diameter, coils per inch, cant amplitude, eccentricity, and spring width) on spring stiffness and maximum Von Mises stress to aid in subsequent design.

  9. Anomalously soft non-Euclidean spring

    NASA Astrophysics Data System (ADS)

    Levin, Ido; Sharon, Eran

    In this work we study the mechanical properties of a frustrated elastic ribbon spring - the non-Euclidean minimal spring. This spring belongs to the family of non-Euclidean plates: it has no spontaneous curvature, but its lateral intrinsic geometry is described by a non-Euclidean reference metric. The reference metric of the minimal spring is hyperbolic, and can be embedded as a minimal surface. We argue that the existence of a continuous set of such isometric minimal surfaces with different extensions leads to a complete degeneracy of the bulk elastic energy of the minimal spring under elongation. This degeneracy is removed only by boundary layer effects. As a result, the mechanical properties of the minimal spring are unusual: the spring is ultra-soft with rigidity that depends on the thickness, t , as t raise 0 . 7 ex 7 7 2 lower 0 . 7 ex 2, and does not explicitly depend on the ribbon's width. These predictions are confirmed by a numerical study of a constrained spring. This work is the first to address the unusual mechanical properties of constrained non-Euclidean elastic objects. We also present a novel experimental system that is capable of constructing such objects, along with many other non-Euclidean plates.

    1990-12-01

    This reports presents the results of a special study undertaken to characterize the riverbank springs (i.e., ground-water seepage) entering the Columbia River along the Hanford Site. Radiological and nonradiological analyses were performed. River water samples were also analyzed from upstream and downstream of the Site as well as from the immediate vicinity of the springs. In addition, irrigation return water and spring water entering the river along the shoreline opposite Hanford were analyzed. Hanford-origin contaminants were detected in spring water entering the Columbia River along the Hanford Site. The type and concentrations of contaminants in the spring water were similar to those known to exist in the ground water near the river. The location and extent of the contaminated discharges compared favorably with recent ground-water reports and predictions. Spring discharge volumes remain very small relative to the flow of the Columbia. Downstream river sampling demonstrates the impact of ground-water discharges to be minimal, and negligible in most cases. Radionuclide concentrations were below US Department of Energy Derived Concentration Guides (DCGs) with the exception {sup 90}Sr near the 100-N Area. Tritium, while below the DCG, was detected at concentrations above the US Environmental Protection Agency drinking water standards in several springs. All other radionuclide concentrations were below drinking water standards. Nonradiological contaminants were generally undetectable in the spring water. River water contaminant concentrations, outside of the immediate discharge zones, were below drinking water standards in all cases. 19 refs., 5 figs., 12 tabs.

  16. Rocky Mountain Carbonate Spring Deposit development

    NASA Astrophysics Data System (ADS)

    Rainey, Dustin Kyle

    Relict Holocene carbonate spring deposits containing diverse biotic and abiotic depositional textures are present at Fall Creek cold sulphur springs, Alberta, Fairmont Hot Springs, British Columbia, and Hot Creek cold springs, British Columbia. The relict deposits are formed mainly of low-magnesium crystalline calcite contained in laterally continuous strata. Paleo-flow regimes were characterized by extensive sheet flow that increased the surface area of spring water exposed to the atmosphere. Calcite precipitated inorganically from spring water that attained CaCO3 supersaturation through agitation-induced CO2 degassing that was facilitated by elevated flow rates and a large surface area as spring water flowed down-slope. Thus, the deposits contain only minor amounts of detrital, mechanically deposited, and biogenic carbonate. Evaporation was only a minor contributor to CaCO3 supersaturation, mainly in quiescent environments. Photosynthetic CO2 removal did not measurably contribute to CaCO3 supersaturation. Calcite crystals precipitated in biotic facies formed from low to moderately supersaturated spring water, whereas abiotic dendrite crystals formed rapidly from highly supersaturated spring water. Calcite passively nucleated on cyanobacteria, bryophytes and macrophytes, and was probably facilitated by cyanobacterial extracellular polymeric substances. Cyanobacterial filaments and stromatolites are integral parts of all three deposits, whereas bryophytes were restricted to the Fall Creek and Hot Creek deposits. Diagenetic microbial degradation of crystalline calcite was common to all three deposits, but recrystallization was limited to the Fall Creek deposit. The amount and location of calcite precipitation relative to the vents was controlled by the concentrations of Ca2+ and HCO3- in solution, and discharge volume fluctuations. Spring water with high [Ca2+] and [HCO 3-] precipitated large amounts of calcite proximal to the vents (e.g. Fairmont), whereas spring

  17. Juvenile Spring Eruption: A Variant of Perniosis?

    PubMed

    Nabatian, Adam S; Rosman, Ilana S; Sturza, Jeffrey; Jacobson, Mark

    2015-09-01

    Juvenile spring eruption (JSE) is a unique condition that typically affects the helices of the ears of boys and young men. The classical clinical picture of JSE includes the abrupt onset of lesions after spending time outdoors in the early spring. Because of the papulovesicular nature of the rash and the history of sun exposure, JSE is considered a variant of polymorphous light eruption. In addition to the term "juvenile spring eruption," this entity has also been described under other less common terms such as "perniosis juvenilis vernalis aurium" or "spring perniosis," which emphasizes the onset in the spring and the possible pathogenic role of cold weather. We present a case of likely JSE with histopathologic features more consistent with perniosis than polymorphous light eruption and present a review the literature. PMID:26291421

    For the past 4 years, the Education and Human Resources Committee has been sponsoring evening panel sessions at the AGU Spring and Fall Meetings. Panelists have discussed their experiences in coping with problems such as balancing their time between work and family, or overcoming barriers to professional growth. At the 1986 AGU Spring Meeting in May 1986, we tried a different format. Rather than presentations by a few panelists followed by questions from the audience, we ran a group discussion in which the entire audience participated.

  1. Spring plant phenology and false springs in the conterminous US during the 21st century

    The onset of spring plant growth has shifted earlier in the year over the past several decades due to rising global temperatures. Earlier spring onset may cause phenological mismatches between the availability of plant resources and dependent animals, and potentially lead to more false springs, when subsequent freezing temperatures damage new plant growth. We used the extended spring indices to project changes in spring onset, defined by leaf out and by first bloom, and predicted false springs until 2100 in the conterminous United States (US) using statistically-downscaled climate projections from the Coupled Model Intercomparison Project 5 ensemble. Averaged over our study region, the median shift in spring onset was 23 days earlier in the Representative Concentration Pathway 8.5 scenario with particularly large shifts in the Western US and the Great Plains. Spatial variation in phenology was due to the influence of short-term temperature changes around the time of spring onset versus season long accumulation of warm temperatures. False spring risk increased in the Great Plains and portions of the Midwest, but remained constant or decreased elsewhere. We conclude that global climate change may have complex and spatially variable effects on spring onset and false springs, making local predictions of change difficult.

    Numerical models of fluid and temperature flow were developed for the Agua Caliente Spring to (1) test the validity of the conceptual model that the Agua Caliente Spring enters the valley-fill deposits from fractures in the underlying basement complex and rises through more than 800 feet of valley-fill deposits by way of a washed-sand conduit and surrounding low-permeability deposits (spring chimney) of its own making, (2) evaluate whether water-level declines in the regional aquifer will influence the temperature of discharging water, and (3) determine the source of thermal water in the perched aquifer. A radial-flow model was used to test the conceptual model and the effect of water-level declines. The observed spring discharge and temperature could be simulated if the vertical hydraulic conductivity of the spring orifice was about 200 feet per day and the horizontal hydraulic conductivity of the orifice (spring chimney) was about 0.00002 feet per day. The simulated vertical hydraulic conductivity is within the range of values reported for sand; however, the low value simulated for the horizontal hydraulic conductivity suggests that the spring chimney is cemented with increasing depth. Chemical data collected for this study indicate that the water at Agua Caliente Spring is at saturation with respect to both calcite and chalcedony, which provides a possible mechanism for cementation of the spring chimney. A simulated decline of about 100 feet in the regional aquifer had no effect on the simulated discharge of Agua Caliente Spring and resulted in a slight increase in the temperature of the spring discharge. Results from the radial-flow- and three-dimensional models of the Agua Caliente Spring area demonstrate that the distribution and temperature of thermal water in the perched water table can be explained by flow from a secondary shallow-subsurface spring orifice of the Agua Caliente Spring not contained by the steel collector tank, not by leakage from the

    2013-06-01

    On 2-3 June 2012, the University of Tromsoe hosted a conference about the cultural and scientific history of the transits of Venus. The conference took place in Tromsoe for two very specific reasons. First and foremost, the last transit of Venus of this century lent itself to be observed on the disc of the Midnight Sun in this part of Europe during the night of 5 to 6 June 2012. Second, several Venus transit expeditions in this region were central in the global enterprise of measuring the scale of the solar system in the eighteenth century. The site of the conference was the Nordnorsk Vitensenter (Science Centre of Northern Norway), which is located at the campus of the University of Tromsoe. After the conference, participants were invited to either stay in Tromsoe until the midnight of 5-6 June, or take part in a Venus transit voyage in Finnmark, during which the historical sites Vardoe, Hammerfest, and the North Cape were to be visited. The post-conference program culminated with the participants observing the transit of Venus in or near Tromsoe, Vardoe and even from a plane near Alta. These Proceedings contain a selection of the lectures delivered on 2-3 June 2012, and also a narrative description of the transit viewing from Tromsoe, Vardoe and Alta. The title of the book, Meeting Venus, refers the title of a play by the Hungarian film director, screenwriter and opera director Istvan Szabo (1938-). The autobiographical movie Meeting Venus (1991) directed by him is based on his experience directing Tannhauser at the Paris Opera in 1984. The movie brings the story of an imaginary international opera company that encounters a never ending series of difficulties and pitfalls that symbolise the challenges of any multicultural and international endeavour. As is evident from the many papers presented in this book, Meeting Venus not only contains the epic tales of the transits of the seventeenth, eighteenth and nineteenth centuries, it also covers the conference

    2001-01-01

    This article addresses a problem of micromagnetics: the reversal of magnetic moments in layered spring magnets. A one-dimensional model is used of a film consisting of several atomic layers of a soft material on top of several atomic layers of a hard material. Each atomic layer is taken to be uniformly magnetized, and spatial inhomogeneities within an atomic layer are neglected. The state of such a system is described by a chain of magnetic spin vectors. Each spin vector behaves like a spinning top driven locally by the effective magnetic field and subject to damping (Landau-Lifshitz-Gilbert equation). A numerical integration scheme for the LLG equation is presented that is unconditionally stable and preserves the magnitude of the magnetization vector at all times. The results of numerical investigations for a bilayer in a rotating in-plane magnetic field show hysteresis with a basic period of 2{pi} at moderate fields and hysteresis with a basic period of {pi} at strong fields.

  6. Spring Dust Storm Smothers Beijing

    A few days earlier than usual, a large, dense plume of dust blew southward and eastward from the desert plains of Mongolia-quite smothering to the residents of Beijing. Citizens of northeastern China call this annual event the 'shachenbao,' or 'dust cloud tempest.' However, the tempest normally occurs during the spring time. The dust storm hit Beijing on Friday night, March 15, and began coating everything with a fine, pale brown layer of grit. The region is quite dry; a problem some believe has been exacerbated by decades of deforestation. According to Chinese government estimates, roughly 1 million tons of desert dust and sand blow into Beijing each year. This true-color image was made using two adjacent swaths (click to see the full image) of data from the Sea-viewing Wide Field-of-view Sensor (SeaWiFS), flying aboard the OrbView-2 satellite, on March 17, 2002. The massive dust storm (brownish pixels) can easily be distinguished from clouds (bright white pixels) as it blows across northern Japan and eastward toward the open Pacific Ocean. The black regions are gaps between SeaWiFS' viewing swaths and represent areas where no data were collected. Image courtesy the SeaWiFS Project, NASA/Goddard Space Flight Center, and ORBIMAGE

    The SPring-8 beamline control system is now taking part in the control of the insertion device (ID), front end, beam transportation channel and all interlock systems of the beamline: it will supply a highly standardized environment of apparatus control for collaborative researchers. In particular, ID operation is very important in a third-generation synchrotron light source facility. It is also very important to consider the security system because the ID is part of the storage ring and is therefore governed by the synchrotron ring control system. The progress of computer networking systems and the technology of security control require the development of a highly flexible control system. An interlock system that is independent of the control system has increased the reliability. For the beamline control system the so-called standard model concept has been adopted. VME-bus (VME) is used as the front-end control system and a UNIX workstation as the operator console. CPU boards of the VME-bus are RISC processor-based board computers operated by a LynxOS-based HP-RT real-time operating system. The workstation and the VME are linked to each other by a network, and form the distributed system. The HP 9000/700 series with HP-UX and the HP 9000/743rt series with HP-RT are used. All the controllable apparatus may be operated from any workstation. PMID:15263588

    This study was conducted to determine the estimated radiation doses that individuals in five nearby population groups and the general population in the surrounding area may have received as a consequence of activities at a uranium processing plant in Weldon Spring, Missouri. The study is retrospective and encompasses plant operations (1957-1966), cleanup (1967-1969), and maintenance (1969-1982). The dose estimates for members of the nearby population groups are as follows. Of the three periods considered, the largest doses to the general population in the surrounding area would have occurred during the plant operations period (1957-1966). Dose estimates for the cleanup (1967-1969) and maintenance (1969-1982) periods are negligible in comparison. Based on the monitoring data, if there was a person residing continually in a dwelling 1.2 km (0.75 mi) north of the plant, this person is estimated to have received an average of about 96 mrem/yr (ranging from 50 to 160 mrem/yr) above background during plant operations, whereas the dose to a nearby resident during later years is estimated to have been about 0.4 mrem/yr during cleanup and about 0.2 mrem/yr during the maintenance period. These values may be compared with the background dose in Missouri of 120 mrem/yr.

    1999-06-08

    The invention provides an elastic actuator consisting of a motor and a motor drive transmission connected at an output of the motor. An elastic element is connected in series with the motor drive transmission, and this elastic element is positioned to alone support the full weight of any load connected at an output of the actuator. A single force transducer is positioned at a point between a mount for the motor and an output of the actuator. This force transducer generates a force signal, based on deflection of the elastic element, that indicates force applied by the elastic element to an output of the actuator. An active feedback force control loop is connected between the force transducer and the motor for controlling the motor. This motor control is based on the force signal to deflect the elastic element an amount that produces a desired actuator output force. The produced output force is substantially independent of load motion. The invention also provides a torsional spring consisting of a flexible structure having at least three flat sections each connected integrally with and extending radially from a central section. Each flat section extends axially along the central section from a distal end of the central section to a proximal end of the central section. 30 figs.

  1. Anomalously Soft Non-Euclidean Springs

    NASA Astrophysics Data System (ADS)

    Levin, Ido; Sharon, Eran

    2016-01-01

    In this work we study the mechanical properties of a frustrated elastic ribbon spring—the non-Euclidean minimal spring. This spring belongs to the family of non-Euclidean plates: it has no spontaneous curvature, but its lateral intrinsic geometry is described by a non-Euclidean reference metric. The reference metric of the minimal spring is hyperbolic, and can be embedded as a minimal surface. We argue that the existence of a continuous set of such isometric minimal surfaces with different extensions leads to a complete degeneracy of the bulk elastic energy of the minimal spring under elongation. This degeneracy is removed only by boundary layer effects. As a result, the mechanical properties of the minimal spring are unusual: the spring is ultrasoft with a rigidity that depends on the thickness t as t7 /2 and does not explicitly depend on the ribbon's width. Moreover, we show that as the ribbon is widened, the rigidity may even decrease. These predictions are confirmed by a numerical study of a constrained spring. This work is the first to address the unusual mechanical properties of constrained non-Euclidean elastic objects.

    1993-11-23

    A nuclear fuel assembly for a pressurized water nuclear reactor has a spring and dimple structure formed in a non-radioactive insert tube placed in the top of a sensor receiving instrumentation tube thimble disposed in the fuel assembly and attached at a top nozzle, a bottom nozzle, and intermediate grids. The instrumentation tube thimble is open at the top, where the sensor or its connection extends through the cooling water for coupling to a sensor signal processor. The spring and dimple insert tube is mounted within the instrumentation tube thimble and extends downwardly adjacent the top. The springs and dimples restrain the sensor and its connections against lateral displacement causing impact with the instrumentation tube thimble due to the strong axial flow of cooling water. The instrumentation tube has a stainless steel outer sleeve and a zirconium alloy inner sleeve below the insert tube adjacent the top. The insert tube is relatively non-radioactivated inconel alloy. The opposed springs and dimples are formed on diametrically opposite inner walls of the insert tube, the springs being formed as spaced axial cuts in the insert tube, with a web of the insert tube between the cuts bowed radially inwardly for forming the spring, and the dimples being formed as radially inward protrusions opposed to the springs. 7 figures.

    The study on the potential development of hot springs for the tourism industry in Malaysiawas conducted. Out of the 40 hot springs covered, the study identified 9 hot springs having a high potential for development, 14 having medium potential and the remaining 17 having low or least potential for development. This conclusion was arrived at after considering the technical and economic feasibility of the various hot springs. Technical feasibility criteria includes geological factors, water quality, temperature and flow rate. The economic feasibility criteria considers measures such as accessibility, current and market potentials in terms of visitors, surrounding attractions and existing inventory and facilities available. A geological input indicates that high potential hot springs are located close to or within the granite body and associated with major permeable fault zones. They normally occur at low elevation adjacent to topographic highs. High potential hot springs are also characterised by high water temperature, substantial flowrate and very good water quality which is important for water-body contact activities such as soaking. Economic criteria for high potential hot springs are associated with good accessibility, good market, good surrounding attractions like rural and village setting and well developed facilities and infrastructures.

    Modern man-made environments, including urban, agricultural, and industrial environments, have complex ecological interactions among themselves and with the natural surroundings. Microbial source tracking (MST) offers advanced tools to resolve the host source of fecal contamination beyond indicator monitoring. This study was intended to assess karst spring susceptibilities to different fecal sources using MST quantitative PCR (qPCR) assays targeting human, bovine, and swine markers. It involved a dual-time monitoring frame: (i) monthly throughout the calendar year and (ii) daily during a rainfall event. Data integration was taken from both monthly and daily MST profile monitoring and improved identification of spring susceptibility to host fecal contamination; three springs located in close geographic proximity revealed different MST profiles. The Giach spring showed moderate fluctuations of MST marker quantities amid wet and dry samplings, while the Zuf spring had the highest rise of the GenBac3 marker during the wet event, which was mirrored in other markers as well. The revelation of human fecal contamination during the dry season not connected to incidents of raining leachates suggests a continuous and direct exposure to septic systems. Pigpens were identified in the watersheds of Zuf, Shefa, and Giach springs and on the border of the Gaaton spring watershed. Their impact was correlated with partial detection of the Pig-2-Bac marker in Gaaton spring, which was lower than detection levels in all three of the other springs. Ruminant and swine markers were detected intermittently, and their contamination potential during the wet samplings was exposed. These results emphasized the importance of sampling design to utilize the MST approach to delineate subtleties of fecal contamination in the environment. PMID:26002893

  6. Lengthening Spring Season in Southwestern North America

    2014-12-01

    Climate is changing rapidly in southwestern North America during the Spring season, a critically important transition season in terms of hydrology, ecosystem dynamics, and water resource management. Major rivers are snow-fed in mountainous headwaters but then flow through a monsoonal region with a Summer precipitation maximum; Spring is the dry season in between snowmelt and monsoon onset and is the principal wildfire season in the Southwest. Evaporation during the warm, dry Spring represents a major hydrologic loss in the surface water budget and is a principal cause of projections of significant decreases in post-snowmelt streamflow, during the first half of the growing season when demand for surface water for irrigated agriculture is highest. As temperatures increase, snowpack is expected to decrease and melt earlier, leading to a smaller and earlier peak in snowmelt runoff. Recent climate model projections suggest that monsoon onset should occur later in the year, delaying the summer rainy season. Each of these effects contributes to projections of a lengthening Spring season, at both the beginning and end of Spring. A longer, warmer Spring season is associated with significant surface drying and increased wildfire risk in the 21st Century across the Southwest. So far changes are observed at the beginning of spring in terms of temperature (increasing) and snowpack (decreasing). Detection of other changes, including metrics of the end of spring, has not been easy, in part due to the huge natural variability of precipitation that affects hydrologic variables in conjunction with temperature. This presentation describes efforts to diagnose and document observed changes in the transitions into and out of the Spring dry season in the Southwest, in variables such as temperature, snowmelt date, timing and magnitude of streamflow, and monsoon onset date.

    Although Palm Springs, California, offers a pleasant desert climate that is often advantageous in treatment of respiratory allergies, physicians should be made aware in referring their patients that definite pollen factors must be taken into consideration in recommending a visit to Palm Springs, and should try to determine the compatibility of their patient's allergic sensitivity pattern and the particular seasonal incidence of pollen concentration in Palm Springs. It is believed that the most important pollens there are those of Bermuda grass, olive tree, mesquite, dicoria, false ragweed, scales, and hymenoclea salsola. A favorable climate alone does not permit a patient to disregard good allergic management. PMID:13160819

    Equations are presented for calculating the stick-force characteristics obtained with a spring-tab type of elevator control. The main problems encountered in the design of a satisfactory elevator spring tab are to provide stick forces in the desired range, to maintain the force per g sufficiently constant throughout the speed range, to avoid undesirable "feel" of the control in ground handling or in flight at low airspeeds, and to prevent flutter. Examples are presented to show the design features of spring tabs required to solve these problems for airplanes of various sizes.

  10. Characterizing Hot Spring Connectivity Using Aqueous Geochemistry in the River Group Springs, Yellowstone NP, Wyoming

    Aunan, M. M.; Lindsey, C.; Price, A. N.; Fairley, J. P., Jr.; Larson, P. B.

    2015-12-01

    Abstract We analyzed the aqueous geochemical components of 11 springs in the River Group, Yellowstone National Park, Wyoming. For the springs sampled, we found pHs ranging from a low of ˜4.8 to a high of ˜9.6; TDS (as inferred from electrical conductivity measurements) was roughly correlated to pH, with the lowest pH spring being the most dilute (373 µS) and the highest pH spring having the second highest conductivity (1384 µS). In combination with a shallow ground temperature survey and visual observations of the relative water levels in the springs, the spring chemistries support a conceptual model of fracture-controlled fluid flow in which individual springs demonstrate a surprising level of flowpath isolation. We hypothesize that variations in flowpath permeability lead to steam-heating of low-pH springs, while nearby circumneutral springs are heated by upwelling liquid hydrothermal fluids, high in chlorid and other dissolved components. If our hypothesis is correct, it implies that vaporand liquid-dominated zones of Model III hydrothermal systems can coexist in close proximity, resulting in a complex surface expression of acid-sulfate and chloride-rich circum-neutral springs.

  11. Biogeochemistry of Hypersaline Springs Supporting a Mid-Continent Marine Ecosystem: An Analogue for Martian Springs?

    NASA Astrophysics Data System (ADS)

    Grasby, Stephen E.; Londry, Kathleen L.

    2007-08-01

    Hypersaline springs that host unique mid-continent marine ecosystems were examined in central Manitoba, Canada. The springs originate from a reflux of glacial meltwater that intrudes into underlying bedrock and dissolved buried salt beds. Two spring types were distinguished based both on flow rate and geochemistry. High flow springs (greater than 10 L/s) hosted extensive marine microbial mats, which were dominated by algae but also included diverse microbes. These varied somewhat between springs as indicated by changes in profiles of fatty acid methyl esters. Culture studies confirmed the presence of sulfate-reducing bacteria in sediments at the high flow sites. In contrast, low flow springs were affected by solar evaporation, increasing salinity, and temperature. These low flow springs behaved more like closed nutrient-limited systems and did not support microbial mats. Direct comparison of the high and low flow springs revealed interesting implications for the potential to record biosignatures in the rock record. High flow springs have abundant, well-developed microbial mats, which desiccate and are cemented along the edges of the spring pools; however, the high mass flux overwhelms any geochemical signature of microbial activity. In contrast, the nutrient-limited low flow sites develop strong geochemical signatures of sulfate reduction, even in the absence of microbial mats, due to less dilution with the lower flows. Geochemical and physical evidence for life did not correlate with the abundance of microbial life but, rather, with the extent to which the biological system formed a closed ecosystem.

    This report has been prepared to provide information about the public safety and environmental protection programs conducted by the Weldon Spring Site Remedial Action Project. The Weldon Spring site is located in southern St. Charles County, Missouri, approximately 48 km (30 mi) west of St. Louis. The site consists of two main areas, the Weldon Spring Chemical Plant and raffinate pits and the Weldon Spring Quarry. The objectives of the Site Environmental Report are to present a summary of data from the environmental monitoring program, to characterize trends and environmental conditions at the site, and to confirm compliance with environmental and health protection standards and requirements. The report also presents the status of remedial activities and the results of monitoring these activities to assess their impacts on the public and environment. The scope of the environmental monitoring program at the Weldon Spring site has changed since it was initiated. Previously, the program focused on investigations of the extent and level of contaminants in the groundwater, surface waters, buildings, and air at the site. In 1992, the level of remedial activities required monitoring for potential impacts of those activities, particularly on surface water runoff and airborne effluents. This report includes monitoring data from routine radiological and nonradiological sampling activities. These data include estimates of dose to the public from the Weldon Spring site; estimates of effluent releases; and trends in groundwater contaminant levels. Also, applicable compliance requirements, quality assurance programs, and special studies conducted in 1992 to support environmental protection programs are reviewed.

    In this Letter, we report a hybrid system consisting of nano-optical and nano-mechanical springs, in which the optical spring effect works to adjust the mechanical frequency of a nanoelectromechanical systems resonator. Nano-scale folded beams are fabricated as the mechanical springs and double-coupled one-dimensional photonic crystal cavities are used to pump the “optical spring.” The dynamic characteristics of this hybrid system are measured and analyzed at both low and high input optical powers. This study leads the physical phenomenon of optomechanics in complex nano-opto-electro-mechanical systems (NOEMS) and could benefit the future applications of NOEMS in chip-level communication and sensing.

    A colleague walked by my office one time as I was conducting a meeting. There were about five or six members of my team present. The colleague, a man who had been with our institution (The Johns Hopkins Applied Physics Lab, a.k.a. APL) for many years, could not help eavesdropping. He said later it sounded like we we re having a raucous argument, and he wondered whether he should stand by the door in case things got out of hand and someone threw a punch. Our Advanced Composition Explorer (ACE) team was a hot group, to invoke the language that is fashionable today, although we never thought of ourselves in those terms. It was just our modus operandi. The tenor of the discussion got loud and volatile at times, but I prefer to think of it as animated, robust, or just plain collaborative. Mary Chiu and her "hot" team from the Johns Hopkins Applied Physics Laboratory built the Advanced Composition Explorer spacecraft for NASA. Instruments on the spacecraft continue to collect data that inform us about what's happening on our most important star, the Sun.

    The mass transfer-water budget method of computing reservoir evaporation was tested on Warm Springs Reservoir, whose contents and surface area change greatly from early spring to late summer. The mass-transfer coefficient computed for the reservoir is two to three times greater than expected and results in a computed evaporation much greater than that from a land pan. Because of the remoteness of the area, the recommended study technique was modified, which could have reduced the accuracy of the results.

    2015-06-01

    This study will use the Mann-Kendall (MK) non-parametric trend test to examine timing changes in spring (early May to the end of June) streamflow records observed by the Water Survey of Canada during 1985-2011 in an Arctic headwater basin in the Western Canadian Arctic. The MK test shows a general delay in the five timing measures of springtime streamflow, which are based on the 5 percentile (Q5), 10 percentile (Q10), 50 percentile (Q50), 90 percentile (Q90), and 95 percentile (Q95) dates of spring runoff, respectively. However, much stronger trend signals were clearly noted for the high percentiles than that for the low and middle percentiles, indicating different effects of hydroclimate processes working on the timing of springtime streamflow. In contrast, the earlier snowmelt onset derived from daily mean temperatures was found over the 27-year study period. In addition, multiple relationships were correlated between these five timing measures of spring runoff and five hydroclimate indicators (total snowfall, snowmelt onset, spring temperature fluctuation, spring rainfall, and spring rainfall timing) in order to identify possible causes on the changes of springtime streamflow timing. The results indicate that the differences are due to the contradictory effects of winter-spring air temperature changes, temperature fluctuation during the melting period, and spring rainfall to spring runoff. The earlier snowmelt onset, which is attributed to the winter-spring warming, and spring temperature fluctuation that works in the opposite way, result in the minor timing changes of Q5, Q10, and Q50. The increase in spring rainfall and its delayed timing have a significant impact on the dates of Q90 and Q95. Moreover, the decreased total snow accumulation over the winter season only has a minor influence on the timing of springtime streamflow.

    This article is an abridgement of Special Report 172, Travertine Hot Springs at Bridgeport, Mono County, California, in preparation at the California Division of Mines and Geology. The Travertine Hot Springs area is on the northern edge of what many consider to be one of the most tectonically active areas in the United States. There is abundant geothermal and seismic activity. The landscape is dotted with volcanic features- cones, craters, domes, flows, fumaroles and hot springs-indicators of unrest in the present as well as reminders of activity in the past. Travertine, also known as calcareous sinter, is limestone formed by chemical precipitation of calcium carbonate (CaCO{sub 3}) from ground or surface waters. It forms stalactites and stalagmites in caves, fills some veins and spring conduits and can also be found at the mouths of springs, especially hot springs. The less compact variety is called tufa and the dense, banded variety is known as Mexican onyx, or onyx marble. True onyx, however, is a banded silicate.

    Polymer springs that twist under irradiation with light, in a manner that mimics how plant tendrils twist and turn under the effect of differential expansion in different sections of the plant, show potential for soft robotics and the development of artificial muscles. The soft springs prepared using this protocol are typically 1 mm wide, 50 μm thick and up to 10 cm long. They are made from liquid crystal polymer networks in which an azobenzene derivative is introduced covalently as a molecular photo-switch. The polymer network is prepared by irradiation of a twist cell filled with a mixture of shape-persistent liquid crystals, liquid crystals having reactive end groups, molecular photo-switches, some chiral dopant and a small amount of photoinitiator. After postcuring, the soft polymer film is removed and cut into springs, the geometry of which is determined by the angle of cut. The material composing the springs is characterized by optical microscopy, scanning electron microscopy and tensile strength measurements. The springs operate at ambient temperature, by mimicking the orthogonal contraction mechanism that is at the origin of plant coiling. They shape-shift under irradiation with UV light and can be pre-programmed to either wind or unwind, as encoded in their geometry. Once illumination is stopped, the springs return to their initial shape. Irradiation with visible light accelerates the shape reversion. PMID:27583641

    1988-07-01

    The composition of noble gases in both gas and water samples collected from Horseshoe Spring, Yellowstone National Park, was found to be depth dependent. The deeper the sample collection within the spring, the greater the enrichment in Kr, Xe, radiogenic {sup 4}He, and {sup 40}Ar and the greater the depletion in Ne relative to {sup 36}Ar. The compositional variations are consistent with multi-component mixing. The dominant component consists of dissolved atmospheric gases acquired by the pool at the surface in contact with air. This component is mixed in varying degree with two other components, one each for gas and water entering the bottom of the pool. The two bottom components are not in equilibrium. In Horseshoe Spring, the bubbles entering at the bottom strip the atmospheric-derived pool gases from the surrounding water while en route to the surface. If the original bottom bubbles are noble gas, as in the case of Horseshoe, the acquired pool gases can then quickly obliterate the original bubble composition. These results are used to demonstrate that Yellowstone spring surface gas samples, and perhaps similarity sampled thermal springs from other hydrothermal systems, have gas abundances that depend more on spring morphology than processes occurring deeper in the hydrothermal system.

    The mighty Mississippi River, from its source at Lake Itasca, Minnesota to the Gulf of Mexico, is approximately 3780 kilometers long and has flooded many times during its history. In April 2001, residents of Minnesota, Wisconsin, Iowa, and Illinois once again battled near-record water levels. These Multi-angle Imaging SpectroRadiometer (MISR) images, acquired one month apart, illustrate the effects of snowmelt and heavy rainfall on areas traversed by the upper Mississippi River.

    Each image in this pair covers an identical 195-kilometer x 339-kilometer area. The one on the left was acquired March 26, 2001 (Terra orbit 6762), and the one on the right is from April 27 (Terra orbit 7228). Both are false-color composites, displaying data from the near-infrared band of the instrument's nadir (vertical-viewing) camera as red; the green band of the nadir camera as green; and the red band of the 26-degree forward camera as blue. Data from the forward-viewing camera is included to enhance the reflectivity of water. The near-infrared data provide a good indicator of the abundance of vegetation since plants are highly reflective in this spectral region. The redder color of the right-hand image is due to increased vegetation cover brought about by wet conditions and the onset of spring.

    Locations of major cities are marked on the left-hand image; major rivers are marked on the right. The portion of the Mississippi River captured in these views extends from just north of La Crosse, Wisconsin to south of Davenport, Iowa. The Wisconsin River joins the Mississippi just below Prairie du Chien. On March 26, snow can clearly be seen over much of the northern portions of the left-hand image. At this point in time, the snow had already begun to melt and the Wapsipinicon River was 52 centimeters above flood stage at De Witt, Iowa (between Clinton and Davenport). By mid-April heavy rainfall swelled the Mississippi and Wisconsin rivers. In the early morning of April 25, two days

    The Odyssey spacecraft has completed a full Mars year of observations of the red planet. For the next several weeks the Image of the Day will look back over this first mars year. It will focus on four themes: 1) the poles - with the seasonal changes seen in the retreat and expansion of the caps; 2) craters - with a variety of morphologies relating to impact materials and later alteration, both infilling and exhumation; 3) channels - the clues to liquid surface flow; and 4) volcanic flow features. While some images have helped answer questions about the history of Mars, many have raised new questions that are still being investigated as Odyssey continues collecting data as it orbits Mars.

    This image was collected June 25, 2003 during the southern spring season. This false color image shows both the layered ice cap and darker 'spots' that are seen only when the sun first lights the polar surface.

    Image information: VIS instrument. Latitude -82.3, Longitude 306 East (54 West). 19 meter/pixel resolution.

    Note: this THEMIS visual image has not been radiometrically nor geometrically calibrated for this preliminary release. An empirical correction has been performed to remove instrumental effects. A linear shift has been applied in the cross-track and down-track direction to approximate spacecraft and planetary motion. Fully calibrated and geometrically projected images will be released through the Planetary Data System in accordance with Project policies at a later time.

    This research deals with the sulfurous spring waters flow along the course of the Euphrates River in western Iraq in the area extended between Haqlaniya and Hit within the Al-Anbar governorate. Eleven springs (3 in Haqlanya, 4 in Kubaysa and 4 in Hit) have been addressed for the purpose of water evaluation for balneology, drinking, irrigation and aquaculture (fish farming). In order to meet the objectives of this research, all springs were sampled and analyzed for the total dissolved solid, electrical conductivity, pH, temperature, major cations (Ca(2+), Mg(2+), Na(+) and K(+)), major anions (SO(4)(2-), Cl(-), HCO(3)(-) and CO(3)(2-)), minor anions (PO(4)(3-)and NO(3)(-)) as well as the trace elements that included Pb, Zn, Cd, Ni, Fe, Mn, Cu, Br, F, Ba, B, Sr, Al, As, Cr, Hg and Se. The International Standards of World Health Organization are used for assessing the water quality. The results revealed that the springs belong to the tepid springs of 27-30 °C and classified as hypothermal to the thermal springs. Lithochemistry and geochemical processes clearly affected the water chemistry. The hydrogeochemical processes are responsible for the element enrichment in water by the chemical dissolution of carbonate and gypsum and evaporation as well. The results of the study indicate the possibility of using spring water for therapeutic purposes, but not allowed for drinking and aquaculture (fish farming), except those free of H(2)S gas. On the other hand, it can be used for irrigation with risk. However, soil type as well as proper selection of plants should be taken into consideration. PMID:23887869

    Groundwater springs are significant landscape features for humans and the biota that occupies their habitat. Many springs become inactive where groundwater exploitation by humans has lowered the water table or artesian pressure. In order to assess this impact, it is important to identify and locate active, and with more difficulty, inactive springs. Using a variety of archival, environmental and field-based data, this study presents a protocol for the determination of the location and status of springs across the Great Artesian Basin of Australia. This protocol underpins a database of springs, which is not only important for the assessment of spring ecosystems, but also contributes to understand groundwater extraction impacts and hydrogeological processes. The database indicates that 30.0% of discharge (artesian) springs in the Great Artesian Basin are entirely inactive and another 11.8% are partially inactive. For the outcrop (gravity) springs of the Basin, only 1.9% are entirely inactive and 7.4% partially inactive, and for the outcrop springs in the Tertiary sandstone overlying the Basin 30.9% are inactive and 18.2% are partially inactive.

  17. AGU testifies on NASA Budget

    Simarski, Lynn Teo

    Witnesses from outside the U.S. government—including Frank Eden, representing AGU—testified about the National Aeronautics and Space Administration's budget on March 12 before the House Science Committee's subcommittee on space. One major topic of the hearing was familiar: what should NASA's top priority be, space science or human exploration of space.“Obviously this committee has a huge job of trying to set priorities—consistent with the budget restraints—that will end up giving the American taxpayer the most bang for his buck, as well as providing direction for our space program,” said F. James Sensenbrenner, Jr. (R-Wis.), the subcommittee's ranking Republican. Another recurring topic, cited by the subcommittee's new chairman, Ralph M. Hall (D-Tex.), as well as by other committee members, was how to translate NASA-developed technologies into commercial gain for the U.S. in the global marketplace. Hall and others also posed a number of questions on a topic the chairman called a special concern of his: whether it would be economically and scientifically plausible for the U.S. to use the Soviet space station Mir for certain activities, such as medical applications.

  2. Radioactive mineral springs in Delta County, Colorado

    USGS Publications Warehouse

    Cadigan, Robert A.; Rosholt, John N.; Felmlee, J. Karen

    1976-01-01

    The system of springs in Delta County, Colo., contains geochemical clues to the nature and location of buried uranium-mineralized rock. The springs, which occur along the Gunnison River and a principal tributary between Delta and Paonia, are regarded as evidence of a still-functioning hydrothermal system. Associated with the springs are hydrogen sulfide and sulfur dioxide gas seeps, carbon dioxide gas-powered geysers, thick travertine deposits including radioactive travertine, and a flowing warm-water (41?C) radioactive well. Geochemical study of the springs is based on surface observations, on-site water-property measurements, and sampling of water, travertine, soft precipitates, and mud. The spring deposits are mostly carbonates, sulfates, sulfides, and chlorides that locally contain notable amounts of some elements, such as arsenic, barium, lithium, and radium. Samples from five localities have somewhat different trace element assemblages even though they are related to the same hydrothermal system. All the spring waters but one are dominated by sodium chloride or sodium bicarbonate. The exception is an acid sulfate water with a pH of 2.9, which contains high concentrations of aluminum and iron. Most of the detectable radioactivity is due to the presence of radium-226, a uranium daughter product, but at least one spring precipitate contains abundant radium-228, a thorium daughter product. The 5:1 ratio of radium-228 to radium-226 suggests the proximity of a vein-type deposit as a source for the radium. The proposed locus of a thorium-uranium mineral deposit is believed to lie in the vicinity of Paonia, Colo. Exact direction and depth are not determinable from data now available.

    This study was conducted to document the normal ultrasound anatomy of the spring ligament in asymptomatic subjects and to prospectively determine the frequency of ultrasound abnormality of the spring ligament in patients with suspected posterior tibial tendinopathy. The superomedial calcaneonavicular ligament (CNL) of 10 healthy volunteers was examined by ultrasound. Nineteen patients with a clinical diagnosis of suspected posterior tibial tendinopathy and/or chronic pain along the course of the tendon were examined by ultrasound. The superomedial CNL thickness was measured. Normal anatomy of the superomedial CNL could be demonstrated in all the volunteers. The mean of the combined proximal measurements was 4 mm and of the distal measurements 3.6 mm. Sixteen patients with posterior tibial tendinopathy had increased thickness of the spring ligament, which was more evident on its distal portion over the talar head. One patient had superomedial CNL insufficiency with normal posterior tibial tendon. The mean proximal measurement in the study group was 5.1 mm and the distal measurement 6.1 mm. The differences between the measurements in the study group and controls were highly significant (proximal site P < 0.01, distal site P < 0.001). Spring-ligament laxity or tear is characterised by thickening. There is a strong association between posterior tibial tendinopathy and abnormality of the spring ligament. PMID:18523776

  4. Geophysical Investigation of Neal Hot Springs

    NASA Astrophysics Data System (ADS)

    Colwell, C.; Van Wijk, K.; Liberty, L. M.

    2011-12-01

    We present newly acquired geophysical data that characterizes a geothermal system at Neal Hot Springs in eastern Oregon. The hot springs are in a region of complex and intersecting fault trends associated with two major extensional events, the Oregon-Idaho Graben and the western Snake River Plain. From surface observations and several boreholes in the area, it appears that a steeply dipping normal fault forms a half-graben basin and serves as a conduit for heated water at depth to migrate to the surface at Neal Hot Springs. We identify and characterize this fault with seismic reflection, gravity, magnetic, and electrical resistivity surveys. A self-potential survey indicates that water is upwelling over the fault plane, and suggests that the fault does provide the means for heated water to migrate to the surface. Smaller scale structure is also evident in both the gravity and seismic surveys, and could interact with the migration of water, and how the hot springs recharge. These preliminary results will be built upon in the upcoming years and a solid structural understanding of Neal Hot Springs and the surrounding area will be gained through the use of geophysics.

  5. Sample Return from Ancient Hydrothermal Springs

    Hydrothermal spring deposits on Mars would make excellent candidates for sample return. Molecular phylogeny suggests that that life on Earth may have arisen in hydrothermal settings [1-3], and on Mars, such settings not only would have supplied energy-rich waters in which martian life may have evolved [4-7] but also would have provided warm, liquid water to martian life forms as the climate became colder and drier [8]. Since silica, sulfates, and clays associated with hydrothermal settings are known to preserve geochemical and morphological remains of ancient terrestrial life [9-11], such settings on Mars might similarly preserve evidence of martian life. Finally, because formation of hydrothermal springs includes surface and subsurface processes, martian spring deposits would offer the potential to assess astrobiological potential and hydrological history in a variety of settings, including surface mineralized terraces, associated stream deposits, and subsurface environments where organic remains may have been well protected from oxidation. Previous attempts to identify martian spring deposits from orbit have been general or limited by resolution of available data [12-14]. However, new satellite imagery from HiRISE has a resolution of 28 cm/pixel, and based on these new data, we have interpreted several features in Vernal Crater, Arabia Terra as ancient hydrothermal springs [15, 16].

  7. Evaluation of acoustic doppler velocity meters to quantify flow from Comal Springs and San Marcos Springs, Texas

    Comal Springs and San Marcos Springs are the two largest springs in Texas, are major discharge points for the San Antonio segment of the Edwards aquifer, and provide habitat for several Federally listed endangered species that depend on adequate springflows for survival. It is therefore imperative that the Edwards Aquifer Authority have accurate and timely springflow data to guide resource management. Discharge points for Comal Springs and San Marcos Springs are submerged in Landa Lake and in Spring Lake, respectively. Flows from the springs currently (2008) are estimated by the U.S Geological Survey in real time as surface-water discharge from conventional stage-discharge ratings at sites downstream from each spring. Recent technological advances and availability of acoustic Doppler velocity meters (ADVMs) now provide tools to collect data (stream velocity) related to springflow that could increase accuracy of real-time estimates of the springflows. The U.S. Geological Survey, in cooperation with the Edwards Aquifer Authority, did a study during May 2006 through September 2007 to evaluate ADVMs to quantify flow from Comal and San Marcos Springs. The evaluation was based on two monitoring approaches: (1) placement of ADVMs in important spring orifices - spring run 3 and spring 7 at Comal Springs, and diversion spring at San Marcos Springs; and (2) placement of ADVMs at the nearest flowing streams - Comal River new and old channels for Comal Springs, Spring Lake west and east outflow channels and current (2008) San Marcos River streamflow-gaging site for San Marcos Springs. For Comal Springs, ADVM application at spring run 3 and spring 7 was intended to indicate whether the flows of spring run 3 and spring 7 can be related to total springflow. The findings indicate that velocity data from both discharge features, while reflecting changes in flow, do not reliably show a direct relation to measured streamflow and thus to total Comal Springs flow.

    Springs are unique ecosystems, but in many cases they are severely threatened and there is an urgent need for better spring management and conservation. To this end, we studied water quality and quantity in springs in Oulanka National Park, north-east Finland. Multivariate statistical methods were employed to relate spring water quality and quantity to hydrogeology and land use of the spring capture zone. This revealed that most springs studied were affected by locally atypical dolostone-limestone bedrock, resulting in high calcium, pH, and alkalinity values. Using Ward's hierarchical clustering, the springs were grouped into four clusters based on their water chemistry. One cluster consisted of springs affected by past small-scale agriculture, whereas other clusters were affected by the variable bedrock, e.g., springs only 1 km from the dolostone-limestone bedrock area were beyond its calcium-rich impact zone. According to a random forest model, the best predictors of spring water chemistry were spring altitude and the stable hydrogen isotope ratio of the water (δ2H). Thus stable water isotopes could be widely applicable for boreal spring management. They may also provide a rough estimate of groundwater flow route (i.e., whether it is mainly local or regional), which largely determines the chemical characteristics of spring water. Our approach could be applied in other boreal regions and at larger spatial scales for improved classification of springs and for better targeted spring management.

    The species richness of wetland ecosystems' are sustained by the presence of discrete groundwater discharge, or springs. Springs provide thermal refugia and a source of fresh water inflow crucial for survival of many wetland species. The subsurface drivers that control the spatial distribution of surficial springs throughout peatland complexes are poorly understood due to the many challenges peatlands pose for hydrologic characterization, such as the internal heterogeneities, soft, dynamic substrate, and low gradient of peat drainage. This has previously made it difficult to collect spatial data required for restoration projects that seek to support spring obligate and thermally stressed species such as trout. Tidmarsh Farms is a 577-acre site in Southeastern Massachusetts where 100+ years of cranberry farming has significantly altered the original peatland hydrodynamics and ecology. Farming practices such as the regular application of sand, straightening of the main channel, and addition of drainage ditches has strongly degraded this peatland ecosystem. Our research has overlain non-invasive geophysical, thermal, and water isotopic data from the Tidmarsh Farms peatland to provide a detailed visualization of how subsurface peat structure and spring patterns correlate. Ground penetrating radar (GPR) has proven particularly useful in characterizing internal peat structure and the mineral soil interface beneath peatlands, we interpolate the peatland basin at a large scale (1 km2) and compare this 3-D surface to the locations of springs on the peat platform. Springs, expressed as cold anomalies in summer and warm anomalies in winter, were specifically located by combining fiber-optic and infrared thermal surveys, utilizing the numerous relic agricultural drainage ditches as a sampling advantage. Isotopic signatures of the spring locations are used to distinguish local and regional discharge, differences that can be explained in part by the peat basin structure

Spring-Loaded Joule-Thomson Valve pressure drop regulated by spring pushing stainless-steel ball against soft brass seat. Pressure drop remains nearly constant, regardless of helium flow rate and of any gas contaminants frozen on valve seat. Because springloaded J-T valve maintains constant pressure drop, upstream roomtemperature throttle valve adjusts flow rate precisely for any given upstream pressure. In addition, new valve relatively invulnerable to frozen gas contaminants, which clog fixed-orifice J-T valves.

    As early as the 7th century B.C. (Western Zhou Dynasty), there is a recording as 'spring which contains sulfur could treat disease' on the Wentang Stele written by WANG Bao. Wenquan Fu written by ZHANG Heng in the Easten Han Dynasty also mentioned hot spring bath treatment. The distribution of hot springs in China has been summarized by LI Daoyuan in the Northern Wei Dynasty in his Shuijingzhu which recorded hot springs in 41 places and interpreted the definition of hot spring. Bencao Shiyi (by CHEN Cangqi, Tang Dynasty) discussed the formation of and indications for hot springs. HU Zai in the Song Dynasty pointed out distinguishing hot springs according to water quality in his book Yuyin Conghua. TANG Shenwei in the Song Dynasty noted in Jingshi Zhenglei Beiji Bencao that hot spring bath treatment should be combined with diet. Shiwu Bencao (Ming Dynasty) classified hot springs into sulfur springs, arsenicum springs, cinnabar springs, aluminite springs, etc. and pointed out their individual indications. Geologists did not start the work on distribution and water quality analysis of hot springs until the first half of the 20th century. There are 972 hot springs in Wenquan Jiyao (written by geologist ZHANG Hongzhao and published in 1956). In July 1982, the First National Geothermal Conference was held and it reported that there were more than 2600 hot springs in China. Since the second half of the 20th century, hot spring sanatoriums and rehabilitation centers have been established, which promoted the development of hot spring bath treatment. PMID:22169492
