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.
For more than 85 years, AGU books have provided access to the work of scientists worldwide and covered exceptional research in the Earth and space sciences. Now more than 80 of our most popular titles are available at discounted prices. AGU members can save up to 75% off titles from the Geophysical Monograph Series, Water Resources Monograph Series, Special Publications, and more.

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

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.

As the ocean sciences have grown in size and scope and matured intellectually and institutionally, scientific communications in many forms have become increasingly important. Fortunately, the AGU offers a broad program of scientific communications. In recent years the AGU has responded to the newly articulated communications needs of the burgeoning ocean sciences community. For example, it has initiated the monthly Oceanography Report in Eos; instituted a separate, alternating oceanography issue of the Green JGR; expanded greatly the time and space allocations of the oceanography sessions at national AGU meetings; supported the Chapman Conference on Ocean Fronts, the International Symposium on Coastal Upwelling, and the first Ocean Sciences Meeting (jointly with ASLO); fostered development of the oceanography luncheons, where timely topics for the community are aired; promoted development of the oceanography careers booklet (in advance preparation); and inaugurated the Coastal and Estuarine Sciences Monograph Series. I consider that not bad for starters!
Ghassan N. Rassam joined the AGU staff today, assuming the dual roles of Division Director for Public Information and Marketing and of Special Assistant for Nonprint Publications. He comes to AGU from the American Geological Institute, where he has been chief editor and assistant director of the GeoRef Information System.As Director of Public Information and Marketing, Rassam will head one of AGU's five divisions. He will have under his purview the Public Information Department and the Promotion and Sales Department. The Public Information Department produces Eos and also has the responsibility for press relations, including the preparation of news releases and the operation of press rooms at meetings. These activities are critical to the implementation of AGU's public education and public affairs initiatives, as well as to the central role of AGU in promoting the unity of geophysics.

The 30th AGU Pacific Northwest Regional Meeting was held September 29 to October 1, 1983, on the campus of Western Washington University, Bellingham, Wash. Approximately 125 attended the meeting, and 36 papers were presented. The meeting included two fields trips, five special symposia, and a banquet where keynote speaker Don Swanson presented “Dome building on Mt. St. Helens.”The meeting highlights included a symposium on Tertiary sedimentary basins of Washington and Oregon which revealed the importance of sedimentological studies for deciphering the timing and nature of accretionary processes in tectonically active areas. Geological and geophysical studies on the recent tectonics of the Juan de Fuca plate and nearby continent were presented by workers from the United States and Canada as well as ongoing studies for the evolution and character of the crystalline North Cascades of Washington and British Columbia.
The Executive Committee of the AGU Hydrology Section met in regular session at 4:00 P.M. on Thursday, December 8, 1983, in Room 378 of the Cathedral Hill Hotel, San Francisco, Calif. Seven board members were present with section president, Peter Eagleson, presiding.A total of 18 sessions were presented in San Francisco, and all were well attended, as was reported by program chairman Dennis Lettenmaier. Added to the regular sessions of General Hydrology, General Ground-water Hydrology, and Sediment Transport were the following special sessions: Glacier Ocean Interaction, presider Edward Josberger; Orinoco and the Amazon, presider Edward Andrews; Transport and Geochemical Interactions in Stream Water, presider F. E. Bencola; Instream Flow Requirements for Fish, presider Brian W. Mar; Multivariate Modeling of Hydrologic and Other Geophysical Time Series, presiders Jose D. Salas and David R. Dawdy; Optimization Techniques for Managing Ground Water and Stream Aquifer Systems, presider Steve Gorelick; Treatment of Evapotranspiration Soil Moisture Evolution and Aquifer Recharge in Watershed Models, presiders Arlen D. Feldman and Hubert J. Morel-Seytoux; Statistical Procedures for Estimating of Flood Risk at Gauged Sites, presider J. R. Stedinger; and Searching for More Physically Based Extreme Value Distributions in Hydrology, presider Juan B. Valdes. The session on Glacier Ocean Interaction received the most publicity, with numerous accounts of some of the presentations appearing in the newspaper. One of the pleasant surprises of the meetings was the high attendance at the special sessions on Optimization Techniques for Managing Ground Water and Stream Aquifer Systems and Multivariate Modeling of Hydrologic and Other Geophysical Time Series. Both sessions were highly interdisciplinary, attracting numerous scientists from other sections of AGU.

Four areas of investigation, each dealing with the measurement of a particular geophysical property, are discussed. These properties are the gravity field, seismicity, magnetism, and heat flow. All are strongly affected by conditions, past or present, in the planetary interior; their measurement is the primary source of information about planetary interiors.
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.
Launched in 1980, the AGU GIFT fund has met with marked success. A special issue of Eos was published in early 1982 (Apr. 20), summarizing the current status of the fundraising efforts. Of particular significance is the rapidly growing list of Individual Supporting Members, which is published elsewhere in this issue.

Steve Jobs, visionary cofounder of Apple, Inc., once said, “Everyone here has the sense that right now is one of those moments when we are influencing the future.” This statement aptly describes AGU at this time as the Board of Directors and the Council continue to influence the future in exciting ways by advancing our strategic plan (http://www.agu.org/about/mission.shtml). Both governing bodies held meetings in San Francisco immediately preceding the 2011 AGU Fall Meeting. The agendas for both meetings, along with the key outcomes, are posted on AGU's Web site (http://www.agu.org/about/governance/).
AGU is a worldwide scientific community that advances, through unselfish cooperation in research, the understanding of Earth and space for the benefit of humanity. AGU is advancing the Earth and space sciences by catalyzing and supporting the efforts of individual scientists within and outside the membership. We are organizing and disseminating information for the scientific community. As a learned society we meet our obligation to serve the public good by fostering quality in the Earth and space sciences and bringing the results of research to the public. These efforts are yielding greater numbers and diversity of well-educated students and young professionals in the Earth and space sciences, and are increasing the public's understanding and appreciation of the value of science and support for it.

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
Fellows of AGU are members who have attained acknowledged eminence in the Earth and space sciences. On 8 December 2007, the Fellows Committee elected 51 members for the class of 2008. Candidates are nominated by colleagues and then vetted by relevant sections and focus groups, who forward the top nominees to the Fellows Committee, which comprises 11 Fellows. Members of the 2006-2008 Fellows Committee are Tuija Pulkkinen, chair, and Shaw Liu, Andrea Rinaldo, Roberta Rudnick, Barbara Romanowicz, Lawrence Mysak, Steve Running, Thomas Herring, Lisa Tauxe, Julian McCreary, and Maria Zuber.

To ensure the highest standards for publication, AGU has begun screening manuscript submissions using CrossCheck (http://www.crossref.org/crosscheck.html) for possible verbatim use of previously published material. Water Resources Research and Geophysical Research Letters have tested this technology since summer 2010. It has proven very useful in ensuring the highest integrity in publication standards and compliance with the AGU dual publication policy (http://www.agu.org/pubs/authors/policies/dualpub_policy.shtml). According to Barbara Major, assistant director of journals, other AGU journals will adopt this screening process in the near future.

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.
On behalf of the Incorporated Research Institutions for Seismology (IRIS) and of the organizing committee of the workshop entitled “Geophysical Hazards and Plate Boundary Processes in Central America, Mexico, and the Caribbean,” I thank AGU for providing funding for the workshop to supplement the core support from the U.S. National Science Foundation and the United States Agency for International Development. The workshop, which was held 24-28 October 2010 in Heredia, Costa Rica, was attended by 87 geophysicists and stakeholders from the public, private, and development sectors from 21 countries. We were able to outline and coordinate initiatives that will contribute to geophysical research and hazard mitigation in the region through international collaboration and to establish a forum to initiate efforts with the potential for immediate societal benefits.

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
AGU is pleased to announce the winners of two student scholarships. Caterina Brighi is the recipient of the 2014 David S. Miller Young Scientist Scholarship, which recognizes a student of the Earth sciences whose academic work exhibits interest and promise.

The Union Fellows Selection Committee is proud to present the 2013 class of AGU Fellows. Established in 1962, the Fellows program recognizes AGU members who have attained acknowledged eminence in the Earth and space sciences as valued by their peers and vetted by a committee of Fellows. The primary criterion for evaluation of scientific eminence is a major breakthrough or discovery, paradigm shift, or sustained impact.
Representatives from AGU's leadership and Wiley fielded questions at a town hall during Fall Meeting that ranged from the pricing of AGU's digital library to the fate of AGU books to the role of the governance structure in approving the AGU-Wiley publications partnership.
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."

A new Committee on Mineral Physics consisting of Orson Anderson (chairman), Peter Bell, Raymond Jeanloz, Robert Lieberman, Murli Manghnani, Alexandra Navrotsky, Tom Shankland, Joseph E. Smith, and Donald Weidner has been approved by the AGU Executive Committee.The increasing number of research groups in an area that combines the study of mineral properties and solid state sciences (materials research) created the impetus for this new committee. At AGU meetings, mineral physics studies have been included in recent years in sessions of Volcanology, Petrology, and Geochemistry and sessions of Tectonophysics. A portion of the charter for the new committee includes arranging special sessions for mineral physics that would bridge the two sections.

The American Geophysical Union, a scientific society of 62,000 members worldwide, has established a set of scientific integrity and professional ethics guidelines for the actions of its members, for the governance of the union in its internal activities, and for the operations and participation in its publications and scientific meetings. This presentation will provide an overview of the Ethics program at AGU, highlighting the reasons for its establishment, the process of dealing ethical breaches, the number and types of cases considered, how AGU helps educate its members on Ethics issues, and the rapidly evolving efforts at AGU to address issues related to the emerging field of GeoEthics. The presentation will also cover the most recent AGU Ethics program focus on the role for AGU and other scientific societies in addressing sexual harassment, and AGU's work to provide additional program strength in this area.
Twenty-two distinguished scientists have been elected Fellows of the Union. Fellows are scientists who are judged by their peers as having attained ackowledged eminence in a branch of geophysics.

The American Geophysical Union (AGU) is home to more than 60,000 scientists from 139 countries. Included in this membership are approximately 20,000 (34%) student and early career members. Many well-established programs within AGU provide a dynamic forum for Earth and Space scientists to advance research, collaborate across disciplines, and communicate the importance and impact of science to society regardless of career stage—programs such as AGU publications, scientific meetings and conferences, honors and recognition, and other educational and scientific forums. Additionally, many AGU program initiatives focusing specifically on supporting student and early career scientists and the global talent pool pipeline ones are actively underway. These include both new and long-standing programs. This presentation will describe (1) the overall demographics and needs in Earth and Space sciences, and (2) AGU's coordinated series of programs designed to help attract, retain and support student and early career scientists—with an emphasis on new programmatic activities and initiatives targeting improved diversity. Included in this presentation are a description of the AGU BrightSTaRS Program, the AGU Berkner Program for international students, a newly established AGU Student & Early Career Conference, the AGU Virtual Poster Showcase initiative, the AGU Meeting Mentor program, and GeoLEAD—an umbrella program being jointly built by a coalition of societies to help address Earth and space sciences talent pool needs.

On Sunday, 4 December, three free family events planned by AGU Education and Public Outreach will lead off this year's Fall Meeting. The events begin at noon with the public lecture, which, AGU is thrilled to announce, will be delivered by NASA astronaut Drew Feustel, who holds a Ph.D. in geophysics. In 2009, Feustel served on the crew of STS- 125, the final space shuttle mission to the Hubble Space Telescope, and, earlier this year, STS-134, which traveled to the International Space Station (ISS). He served as the lead space walker during STS-134; the mission delivered to ISS the Alpha Magnetic Spectrometer (AMS), a state-of-the-art cosmic ray particle physics detector designed to examine fundamental issues about matter and the origin and structure of the universe. He will speak about the Hubble STS-125 mission and the STS-134 mission, as well as about how his experiences as a geophysicist influenced his experiences as an astronaut.

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.
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.
AGU is pleased to announce the winners of two scholarships. Marc Neveu is the recipient of the 2013 David S. Miller Young Scientist Scholarship, which recognizes a student of the Earth sciences whose academic work exhibits interest and promise. Hima Hassenruck-Gudipati is the 2013 recipient of the David E. Lumley Scholarship, which recognizes a high-achieving student who is working on problems of global importance in the energy and environmental sectors of industry and academia.
The Ocean Sciences Section of the AGU recognizes Feenan D. Jennings' 25 years of excellent service and successful leadership in the ocean sciences community. He earned the B.S. degree at New Mexico State University (1950) and pursued graduate studies at Scripps and the University of California at Los Angeles. Feenan's career in marine research management began when he left his position as Senior Engineer at the Scripps Institution of Oceanography in 1958 to become Head Oceanographer of the Geophysics Branch of ONR, a position he held until 1966. During his career with ONR, one of his additional duties was subelement monitor for basic research funds earmarked for oceanography. This important function involved monitoring, reporting and helping to defend the expenditure of all oceanographic basic research funds spent by the Navy. He was also instrumental in formulating and carrying through a ten-year ship plan which resulted in the construction of most of the large oceanographic vessels now used by the U.S. academic community.

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.

Recently, Russell and Reiff  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.

AGU will sponsor Rebecca French and Ian Lloyd as Congressional Science Fellows for the 2011-2012 term. French and Lloyd will each work for a year in the office of a senator, representative, or congressional committee, and they will join 30 other Fellows selected by other scientific societies to contribute their scientific knowledge to the policy-making process. French and Lloyd were selected in March by a panel of AGU members who have served as past Congressional Science Fellows after a competitive review process. Their term will mark the 34th year that AGU has sponsored a Fellow and the second year that AGU has sponsored two Fellows concurrently.

AGU journals continue to rank highly in the 2011 Journal Citation Reports (JCR), which was released by Thomson Reuters on 28 June. The impact factor of several AGU journals increased significantly, continuing their trend over the previous 5 years, while others remained consistent with the previous year's ranking. Paleoceanography is an outstanding performer in both the Paleontology and Oceanography categories. Since 1995, Paleoceanography has been the top-ranked journal in the Paleontology category (of 49 titles in 2011), with an Impact Factor of 3.357. In the Oceanography group (59 journals total), Paleoceanography ranks third in Impact Factor. Reviews of Geophysics, with an Impact Factor of 12.364 (an increase of 2.826 from the prior year's score of 9.538), ranks second in Geochemistry and Geophysics out of a total of 77 journals in this cohort. Water Resources Research comes in at second place in the Limnology group, with 19 titles, and third place in the Water Resources group, which has a cohort of 78 titles.

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.
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.
AGU has introduced several new features aimed at simplifying and improving the submission of papers to AGU journals. Enhanced PDF and HTML formats and new journal home pages developed with our publishing partner, Wiley, will also provide improvements for readers. In previous issues of Eos, we provided broader overviews of AGU publications, including the transition to Wiley and open access (Eos, 94(30), 264-266, doi:10.1002/2013EO300009; Eos, 94(39), 345, doi:10.1002/2013EO390006).

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.
The last two years have witnessed many major geophysical events such as the Loma Prieta earthquake, new insights into plate motions, new seismic and mid-ocean ridge observational programs, and new views of a distant planet. AGU's Public Information Committee, chaired by Debra Knopman of the U.S. Geological Survey, was asked by the American Institute of Physics to prepare a series of articles on the major topics in geophysics for publication in Physics News in 1990. Several of those papers did appear in the AIP publication. In the absence of a comparable publication devoted solely to a summary of news in geophysics, AGU is publishing the 20 articles solicited by the Public Information Committee as a booklet, Geophysics News 1990, that is being distributed to the media. The articles are also being published in Eos starting with this issue and continuing for the next several weeks. The topics covered in these articles range from the world's deepest rocks to the powerful blast waves from major solar flares.
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.
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.

The Union Fellows Selection Committee is proud to present the 2014 class of AGU Fellows. Established in 1962, the Fellows program recognizes AGU members who have attained acknowledged eminence in the Earth and space sciences as valued by their peers and vetted by a Union-wide committee of Fellows. Primary criteria for evaluation in scientific eminence are a major breakthrough or discovery, paradigm shift, or sustained impact.
Cynthia L. Bravo, director of the Meetings and Member Programs Division at AGU headquarters, last week celebrated her 25th anniversary as a member of the AGU staff. The only other person to have achieved this distinction is Waldo E. Smith, AGU Executive Director Emeritus.When Cynthia reported for work on November 21, 1960, she became the 13th member of the Union's headquarters staff. Although her official title was clerk-typist, she was immediately dispatched to the mail room to send ballots to the 6267 AGU members (Thomas F. Malone was running unopposed for President and George P. Woollard and Charles A. Whitten were running for Vice President). Two weeks later, she was promoted to subscription supervisor. Although ensuing promotions did not follow as quickly, in her 25 years at AGU, Cynthia has worked in a variety of positions: as head of staff services, administrative assistant to the office manager, administrative assistant to the executive director, meetings manager, and member programs manager. On January 1, 1980, she became director of what is now called the Meetings and Member Programs Division, which serves the more than 18,000 current members and encompasses all programs except publications.
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
Geophysics and geology publications by the U.S. Geological Survey were awarded one first- and two third-place prizes at the ‘Blue Pencil’ ceremony last month, sponsored by the National Association of Government Communicators.First place in the news release category went to Frank Forrester, an AGU member and recently retired USGS information officer. Editors and artists of the bimonthly USGS Earthquake Information Bulletin were awarded third place in the category for technical magazines using at least two colors.
Craddock, Robert A.
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?
Recently, 14 AGU members who joined the Union in 1937 received their recognition pins for 50 years of membership in the Union. They join the distinguished ranks of the 50- year AGU members, who are listed below by the year that they joined:1937 A.B. Bryan, Leonard B. Corwin, Tate Dalrymple, Richard H. Fleming, Harry L. Frauenthal, Konrad B. Krauskopf, J. Stuart Meyers, Brian O'Brien, Joseph F. Poland, Edward J. Rutter, Noel H. Stearn, John P. Tully, Victor Vacquier, G.H. Westby, and Harvey O. Westby.
The Edmond M. Dewan Young Scientist Scholarship fund has reached its goal of $25,000. Those who donated to the fund share AGU's mission in taking an active role in educating and nurturing the next generation of scientists and ensuring a sustainable future for society. Thanks to the generosity of more than 100 members of the AGU and science community, a deserving graduate student of atmospheric or space physics will receive financial assistance to further his or her research and advance his or her research and future career.

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.

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 email@example.com.
Billy Williams, who will join AGU as its new director of science on 15 June, will work to raise AGU's profile and impact and shape AGU's scientific activities and the development of scientific careers for AGU student members. As director of science, Williams will facilitate working relationships and communication of scientific information and resources between and among the AGU Board and Council, committees, sections and focus groups, AGU members (including students), staff, and external partners. In addition, he will facilitate and coordinate the development and implementation of memorandums of understanding and other collaborations with various scientific societies, and he will provide leadership for AGU's efforts to develop resources designed to assist students in preparing for scientific careers. Williams also will serve as senior staff member to the AGU Council.

The Sulzman Award for Excellence in Education and Mentoring (Biogeosciences section) recognizes AGU members who have sustained an active research career in a field related to biogeosciences while excelling as teachers and serving as role models for the next generation of female scientists. This new award acknowledges the importance of female mentors in enhancing gender balance in physical science career paths. The award is being endowed to honor Elizabeth Sulzman, an isotope biogeochemist and soil scientist, whose enthusiasm for teaching awed many undergraduates at Oregon State University. Current plans are to present the first Sulzman award at the 2013 Fall Meeting. Applicants must be women who are within 15 years of receiving their Ph.D., and nomination packages should include a cover letter, resumé, and three letters of recommendation. As they become available, more details will be posted on the Biogeosciences section Web site (http://www.agu.org/sections/biogeo/). The award will provide up to $1000 to one successful nominee each year, although the exact monetary amount is yet to be determined. AGU is currently accepting donations to endow this award; contact Victoria Thompson (firstname.lastname@example.org) to get involved.

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.
AGU has endorsed the U.S. Department of the Interior plan, released on 1 February, to ensure scientific and scholarly integrity throughout the agency's research and program operations (see the news item on page 46 of this Eos issue). “DOI's new plan recognizes the importance of scientific and scholarly integrity in building trust in science that informs public policy,” AGU president Michael J. McPhaden said. “Integrity of the scientific enterprise is essential for guiding the scientific community, policy makers, and the general public as we work together to meet global challenges related to climate change, natural hazards, and wise use of our natural resources.”
Gavin Schmidt, a climate scientist at the NASA Goddard Institute for Space Studies and cofounder of the RealClimate blog (http://www.realclimate.org/), received the first AGU Climate Communication Prize at the honors ceremony. The prize recognizes excellence in climate communication as well as the promotion of scientific literacy, clarity of messaging, and efforts to foster respect and understanding for science-based values related to climate change. Sponsored by Nature's Own—a Boulder, Colo.-based company specializing in the sale of minerals, fossils, and decorative stone specimens—the prize comes with a $25,000 cash award. "AGU created this award to raise the visibility of climate change as a critical issue facing the world today, to demonstrate our support for scientists who commit themselves to the effective communication of climate change science, and to encourage more scientists to engage with the public and policy makers on how climate research can contribute to the sustainability of our planet," said AGU president Michael Mc Phaden. "That's why we are so pleased to recognize Gavin for his dedicated leadership and outstanding scientific achievements. We hope that his work will serve as an inspiration for others."

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

The history programs of the American Institute of Physics -- the Center for History of Physics and the Niels Bohr Library & Archives -- maintain a wide variety of research resources for the history of physics generally, and for the history of geophysics in particular. AIP has over 20,000 photographs online, nearly 1000 oral history interview transcripts, and much more. The International Catalog of Sources provides an online union catalog of manuscript collections held worldwide. An important collection of IUGG records is available onsite, as also is the recently accessioned collection of AGU papers. As the 2019 centenary of AGU approaches, these resources will be of interest to both AGU members and historians of science.;
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.
As the 1979-1980 AGU Congressional Science Fellow, I spent an exciting year working in the personal office of Senator Paul E. Tsongas (D-Mass.). My academic training provided me with an important analytical framework from which to approach issues. The Senate, of course, knows no disciplinary bounds, and limited staff size precludes concentration on a single issue; hence I found myself responsible for a wide range of topics. Nonetheless, I believe that being comfortable with analytical approaches to evaluating problems enables a Congressional Fellow to participate effectively in the necessary political processing of many diverse issues.
John F Mink, an AGU member (Hydrology) for 50 years, and husband of the late Representative Patsy T. Mink (D-Hawaii), will run in a special election on 30 November to fill the remainder of his wife's unexpired congressional term. Patsy Mink, who represented the 2nd Congressional District of Hawaii, passed away on 28 September after battling pneumonia.Her name will appear on the 5 November election ballot as a candidate for Hawaii's 2nd District in the 108th Congress. If she is elected posthumously, the state of Hawaii will hold a special election in January to select an official to serve the full two-year term.
AGU journals continue to rank highly in many categories in the 2010 Journal Citation Report (JCR), which was released by Thomson Reuters on 28 June. JCR reports on several measures of journal usage, including a journal's Eigenfactor score, its Article Influence score, its Impact Factor, and its rank within a cohort of similar journals. According to the 2010 statistics, AGU again has outperformed its larger competitors. Four different AGU titles are ranked in the top three journals in six different cohorts. The Impact Factor of several AGU journals increased significantly over the previous year.

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

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.
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.

To identify groups of cancer survivors that are at increased risk for multiple primary cancers, investigators led an effort to provide the first comprehensive population-based analysis of the risk of subsequent cancer in the U.S., resulting in a monograph.
When I applied for AGU's Congressional Science Fellowship, I promised that I would be completed with my degree requirements before the fellowship began. Thanks to a flexible advisor, I defended my dissertation on August 28, packed my office on August 29, and drove to Washington the next day to participate in a two-week orientation for the fellowship. The orientation, organized by the American Association for the Advancement of Science (AAAS) for incoming Science and Technology Fellows, introduced us to various aspects of the federal government, science policy and life in Washington. During my first week in Washington, I thought my biggest challenge would be finding time to format my dissertation between all the receptions and dinners AAAS scheduled for the Fellows.

Papers presented at a two-day jointly sponsored IAHS/AGU symposium on groundwater contamination are briefly summarized. This international symposium was held 11 12 May, 1989, in Baltimore, Maryland. Presentations encompassed recent research developments in three general areas: abiotic and biotic processes governing contaminant transport; aquifer rehabilitation; and the influence of agricultural practices and nonpoint sources on aquifer quality. Contributions offered an interesting mixture of theoretical, mathematical, laboratory, and field studies. In the first session, transport processes explored ranged from dispersion and fingering to nonequilibrium sorption, metals complexation, and bacteria migration. The use of optimization modeling in the design of remediation strategies was the focus of another session. Here theoretical studies were presented alongside case histories of aquifer rehabilitation. In a final session, a number of models for agricultural management were described. These presentations were complemented by case studies of actual aquifer degradation resulting from land-use and management practices.
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.

Introduction Although effects of rotational motions due to earthquakes have long been observed (e. g., Mallet, 1862), nevertheless Richter (1958, p. 213) stated that: 'Perfectly general motion would also involve rotations about three perpendicular axes, and three more instruments for these. Theory indicates, and observation confirms, that such rotations are negligible.' However, Richter provided no references for this claim. Seismology is based primarily on the observation and modeling of three-component translational ground motions. Nevertheless, theoretical seismologists (e.g., Aki and Richards, 1980, 2002) have argued for decades that the rotational part of ground motions should also be recorded. It is well known that standard seismometers are quite sensitive to rotations and therefore subject to rotation-induced errors. The paucity of observations of rotational motions is mainly the result of a lack, until recently, of affordable rotational sensors of sufficient resolution. Nevertheless, in the past decade, a number of authors have reported direct observations of rotational motions and rotations inferred from rigid-body rotations in short baseline accelerometer arrays, creating a burgeoning library of rotational data. For example, ring laser gyros in Germany and New Zealand have led to the first significant and consistent observations of rotational motions from distant earthquakes (Igel et al., 2005, 2007). A monograph on Earthquake Source Asymmetry, Structural Media and Rotation Effects was published recently as well by Teisseyre et al. (2006). Measurement of rotational motions has implications for: (1) recovering the complete ground-displacement history from seismometer recordings; (2) further constraining earthquake rupture properties; (3) extracting information about subsurface properties; and (4) providing additional ground motion information to earthquake engineers for seismic design. A special session on Rotational Motions in Seismology was convened by H
AGU publishes great science, which is recognized in several ways. One of the most widely recognized is from Thomson Reuters, which provides the Journal Citation Report (JCR) each year as a component of the Web of Science®. JCR reports on several measures of journal usage, including a journal's Eigenfactor score, its Article Influence score, its Impact Factor, and its rank within a cohort of similar journals. According to the 2009 statistics released last week, AGU again has outperformed its larger competitors. For the twelfth time, two different AGU titles hold the top rank in their categories, and AGU titles hold the second spot in two other categories and third in two more.
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.
The 2012 Fall Meeting Editors' Evening, held at the City Club of San Francisco, was hosted by the Publications Committee and is the premier social event for editors and associate editors attending the Fall Meeting. The evening commenced with a welcome from Carol Finn, incoming AGU president, in which she expressed her thanks to the editors and associate editors for volunteering their time to benefit AGU.

In the 23 July 2013 issue of Eos, we provided a broad update on recent events in AGU publishing, focusing on the partnership with John Wiley & Sons (Eos, 94(30), 264-266, doi:10.1002/2013EO300009). Here we briefly comment on the latest developments in the partnership, but the main focus is on recent events regarding open access as it relates to AGU publishing.
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).

AGU Chapman Conference on Biogeophysics; Portland, Maine, 13-16 October 2008; Geophysical methods have the potential to detect and characterize microbial growth and activity in subsurface environments over different spatial and temporal scales. Recognition of this potential has resulted in the development of a new subdiscipline in geophysics called 'biogeophysics,' a rapidly evolving Earth science discipline that integrates environmental microbiology, geomicrobiology, biogeochemistry, and geophysics to investigate interactions that occur between the biosphere (microorganisms and their products) and the geosphere. Biogeophysics research performed over the past decade has confirmed the potential for geophysical techniques to detect microbes, microbial growth/biofilm formation, and microbe-mineral interactions. The unique characteristics of geophysical data sets (e.g., noninvasive data acquisition, spatially continuous properties retrieved) present opportunities to explore geomicrobial processes outside of the laboratory, at unique spatial scales unachievable with microbiological techniques, and possibly in remote environments such as the deep ocean. In response to this opportunity, AGU hosted a Chapman Conference with a mission to bring together geophysicists, biophysicists, geochemists, geomicrobiologists, and environmental microbiologists 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 generate a road map for establishing biogeophysics as a critical subdiscipline of Earth science research.

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.
As part of AGU's 75th Anniversary year, entries are sought for the 1994 Geophysical Images Contest. Over ninety photographs, computer graphics, posters, maps, slides, and videos were submitted in 1993. The winning images were displayed at the AGU Spring Meeting in Baltimore, and again at the Fall Meeting in San Francisco, along with the other images submitted.First place winner in the computer graphics section was “Western Mediterranean Sea Salinity Field,” submitted by Jacques Haus. Honorable Mentions went to Wei-jia Su for “A View of Whole Mantle Heterogeneity” and Toshiro Tanimoto, Paul Morin, David Yuen, and Yu-Shen Zhang for “Visualization of the Earth's Upper Mantle.”

A new AGU initiative to convey current science to the press and public culminated May 18 with a press conference in Washington, D.C., that aired the latest research on volcanoes and climate. AGU released its first special report, “Volcanism and Climate Change,” at the event, and AGU headquarters has been receiving a steady stream of requests for it from the media and others. Both the report and the press conference focused on results of the AGU Chapman Conference on Climate, Volcanism, and Global Change, held March 23-27, 1992, in Hilo, Hawaii.media was conceived by AGU Public Information Committee member William Graustein last November, and the committee added a press conference as a way to expand the Union's role in delivering accurate scientific information to the public, according to Debra Knopman, committee chair. The committee chose the Hilo conference as a test case because it dealt with global change, a topic of clear public interest. By publicizing an emerging area of research discussed at a recent meeting, the report and press conference would also show the scientific process at work, Knopman said

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.

A team of expert writers and lead states, headed by the nonproft education reform organization Achieve (http://www.achieve.org), is in the process of developing the Next Generation Science Standards (NGSS). As a critical stakeholder with a strategic interest in talent pool development, AGU has been interested and involved in the development of the standards since early in the process. AGU members such as Michael Wysession and Ramon Lopez are on the writing team. AGU members and the public are encouraged to read and comment on the standards at http://www.nextgenscience.org/. The frst draft comment period recently closed; however, a comment period on the second draft will open in fall 2012.
In furtherance of our strategic goal to be a diverse and inclusive organization that uses its position to build the global talent pool in Earth and space science, AGU signed a memorandum of understanding with the Earth Science Women's Network (ESWN) in spring 2012. Under the agreement, AGU will provide ESWN with an online platform through which to better connect its members. The agreement will allow AGU to further its strategic goal and help ESWN enhance cooperation and collaboration among women in Earth and space science. ESWN is a community of scientists dedicated to supporting collaborations and providing mentorship for its members, many of whom are in the early stages of their careers. The new online platform should help ESWN to connect with more individuals and create a stronger network of dedicated women pursuing research in Earth and space science.
Geophysical measurements involve no magic or mystery but straightforward applications of physical principles. This book is both a geophysical survey and a reference guide. It explains the physical principles involved in geophysical methods. Over one-third of the text is devoted to seismic methods. Comprehensive topics in the volume include: the measurement of different physical properties and their geological significance; how different kinds of measurements are combined to draw geological conclusions; surface, borehole, airborne, and satellite measurements; computer processing and interactive methods; geodetic, gravity, magnetic, radioactive, heat flow, and electrical methods; interpretation of natural processes such as earthquakes and heat flow; and a summation of present knowledge of the earth.
AGU has selected Erica Bickford and Kevin Reed as its 2012-2013 Congressional Science Fellows. This term will mark the 35th year that AGU has sponsored fellows to serve in Congress. Bickford and Reed will be part of a cohort comprising more than 30 fellows working on Capitol Hill in the coming year and contributing their scientific knowledge to the policy-making process. Erica Bickford is working toward finalizing her Ph.D. in environment and resources from the University of Wisconsin this summer.

As an organization, AGU is indeed fortunate. Our Union has a growing membership worldwide with an average annual increase of 5.9% over the last 5 years. We are financially strong; we have planned carefully and managed our assets and our annual budgets so that we are able to navigate difficult times. Our Fall Meeting is ``the'' event for Earth and space scientists from more than 100 countries. Our publications continue to grow and evolve. Our outreach programs are gaining recognition in the communities we serve. Our development efforts are strengthening our ability to do more without taxing the revenues from meetings and publications. AGU is a preeminent scientific society.

Less than a year ago, AGU had yet to explore the world of science blogging. Now AGU not only has three blogs of its own but also has launched the AGU Blogosphere, a network of independent Earth and space science blogs hosted under the Union's umbrella. The new network of blogs, composed of seven external blogs written by scientists and covering topics including planetary exploration, landslides, Washington, D. C.-area geology, volcanoes, climate change, and more, can now be found together with the in-house blogs at http://blogs.agu.org. It's been a fast, exciting immersion into the blogosphere for AGU. Efforts began with the 2009 Fall Meeting blog, run by AGU staff with the invaluable help of science writing students at University of California, Santa Cruz and New York's Columbia University. This successful experience inspired AGU outreach staff to make a permanent meetings blog, which regularly covers the science presented at AGU meetings.

Are you interested in the intersection of science and policy, looking to make an impact on Capitol Hill, or concerned about the increasing number of attacks against scientists and their academic freedom? AGU Public Affairs offers many events at the 2012 Fall Meeting to assist member involvement in political processes and inform scientists of their rights and options should their research come under legal fire. Learn how you can share your science with policy makers to help inform policy at two luncheon events at the Fall Meeting. If you have ever considered working as a science expert for a member of Congress or reporting science in a mass media outlet, then you should attend the first luncheon, How to be a Congressional Science Fellow or Mass Media Fellow. The event will feature current AGU Congressional Science Fellows detailing their experiences working in Congress as well as past AGU Mass Media Fellows sharing their stories of reporting for a news organization. The luncheon will be held on Tuesday, 4 December, from 12:30 to 1:30 P.M. at the Marriott Hotel, in room Golden Gate B. In addition, current and former fellows will be available for one-on-one interactions at the AGU Marketplace from 3:30 to 4:30 P.M. on Tuesday, 4 December, through Thursday, 6 December.
This monograph deals with all 95 names described in the Cucurbitaceae genus Coccinia and recognizes 25 species. Taxonomic novelties are Cocciniaadoensisvar.aurantiaca (C.Jeffrey) Holstein, stat. nov., Cocciniasessilifoliavar.variifolia (A.Meeuse) Holstein, stat. nov., and Cocciniaadoensisvar.jeffreyana Holstein, var. nov. For the 25 species 3157 collections were examined, of which 2024 were georeferenced to produce distribution maps. All species are distributed in sub-Saharan Africa with one species, Cocciniagrandis, extending from Senegal in West Africa east to Indonesia and being naturalized on Pacific Islands, in Australia, the Caribbean, and South America. Coccinia species are dioecious creepers or climbers with simple or bifid tendrils that occupy a range of habitats from arid scrubland, woodlands to lowland rainforest and mist forest. The corolla of Coccinia species is sympetalous, usually pale yellow to orange, and 1 to 4.5 cm long. Pollination is by bees foraging for pollen or nectar. After pollination, the developing ovary often exhibits longitudinal mottling, which usually disappears during maturation. All species produce berries with a pericarp in reddish colors (orange-red through to scarlet red), hence the generic name. The globose to cylindrical fruits contain numerous grayish-beige flat to lenticular seeds. Chromosome numbers are 2n = 20, 24, and 22 + XX/XY. Many Coccinia species are used for food, either as roasted tubers, greens as spinach, or the fruits as vegetables. Medicinal value is established in Cocciniagrandis, of which leaves and sap are used against diabetes.

At the annual meeting of the American Geophysics Union (AGU) in San Francisco on 7-11 December, catastrophes came in all sizes. On the molecular level, atmospheric chemists had news about the manmade compounds destroying the ozone shield-and for once the news was good. More earthshaking were signs of long-distance connections among earthquakes. And from farther afield came reports of odd-shaped debris from mini-planet collisions.

Geophysics research has long been dominated by classical mechanics, largely disregarding the potential of particle physics to augment existing techniques. The purpose of this article is to review recent progress in probing Earth's interior with muons and neutrinos. Existing results for various volcanological targets are reviewed. Geoneutrinos are also highlighted as examples in which the neutrino probes elucidate the composition of Earth's deep interior. Particle geophysics has the potential to serve as a useful paradigm to transform our understanding of Earth as dramatically as the X-ray transformed our understanding of medicine and the body.

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 . 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. 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, which is also transcriptionally regulated by carbon catabolic repression (CCR) via glucose, but not by other sugars such as lactose and galactose , . Here we report the transcriptional profiling of the aguR gene deletion mutant (L. lactis subsp. cremoris CECT 8666 ∆aguR)  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
AGU has taken the latest step in building strategic alliances with partner groups by signing a memorandum of agreement with the Asia Oceania Geosciences Society (AOGS). This agreement is based on the common interests of our members and will allow us to strengthen our respective organizations by - exchanging information on key programs and initiatives; - expanding membership of both our organizations through possible joint programs; - offering additional educational opportunities, professional services, and student programs; and - extending benefits to members of both organizations.
When a court last month convicted seismologists of wrongdoing for how they characterized earthquake risk in the weeks preceding a deadly 2009 temblor in the city of L'Aquila, Italy, the verdict shocked scientists around the world. More than a year before that judgment came down, freelance reporter Stephen S. Hall had explored the legal case and its implications for scientists and for society in an article published in the 15 September 2011 issue of Nature. Because of the deep and compelling way in which Hall reported on the case, AGU in July chose Hall as the 2012 winner of the Walter Sullivan Award for Excellence in Science Journalism - Features. Remarkable coverage of an earthquake also stood out for judges of the other of this year's AGU journalism honors: the 2012 David Perlman Award for Excellence in Journalism - News. Also in July, AGU selected a team at The Washington Post, including two staff writers, Brian Vastag and Steven Mufson, and the Post's graphics staff, to receive the Perlman Award for their superb reporting on the unusual 5.8 magnitude earthquake that shook the Washington, D. C., region in August 2011.
Maeve Boland, research assistant professor at the Colorado School of Mines, is AGU's 2009-2010 Congressional Science Fellow. Boland, who has a Ph.D. in geology from the Colorado School of Mines, is spending a year working in the office of U.S. Sen. Byron Dorgan (D-N. D.). She was selected in March by AGU's Committee on Public Affairs after a competitive interview process, and she is AGU's 32nd Congressional Science Fellow. In September, Boland and 31 other Congressional Science Fellows participated in a 2-week course in politics and the legislative process put on by the American Association for the Advancement of Science. She then interviewed with a number of congressional offices and was offered a position in the office of Sen. Dorgan, who chairs the Senate Appropriations Subcommittee on Energy and Water Development and is a member of the Committee on Energy and Natural Resources and the Committee on Commerce, Science, and Transportation. Boland is working as a legislative fellow carrying out a range of duties such as organizing congressional hearings, crafting legislation, advising legislators on votes, meeting with lobbyists, and writing speeches. Fellows also are often asked to assist their senator or representative during committee hearings and on the U.S. House or Senate floors during legislative debates.

Cox was presented AGU's John Adam Fleming Medal in 1969, John Verhoogen described Cox's work as “characterized by painstaking care, proper attention to and use of statistics, and great insight.” Those same thoughts were echoed on February 3, 1987, during the memorial service for Cox, who died in a bicycling accident on January 27. The Stanford Memorial Church was crowded with colleagues, students, and friends.The Fleming Medal was presented to Cox in recognition of his studies on the fluctuation of the geomagnetic field. These studies helped to confirm theories of continental drift and seafloor spreading. The medal is awarded annually by AGU for original research and technical leadership in geomagnetism, atmospheric electricity, aeronomy, and related sciences. In addition to the Fleming Medal, Cox received the Antarctic Service Medal in 1970, the Vetlesen Prize in 1971, and the Arthur L. Day Prize of the National Academy of Sciences in 1984. He was a Fellow of AGU and a member of the National Academy of Sciences.

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.

-hazards. The three papers by B Zhao et al and Z Zhao et al address the problem of earthquake strong ground motion in urban regions using case studies from Osaka, Japan and the city of Yinchuan, China. The other two papers study the geological hazard of surface subsidence using geophysical tools: G Leucci reported a comprehensive study in Nardo, Italy, while Kim et al reported a similar case study for a small city in South Korea. One striking feature of all the papers in this special issue is that multiple authors with at least 3 co-authors wrote the majority of the papers, which is an indication of strong team work and interdisciplinary collaboration. This is essential for the successful application of geophysical science and technology in tackling a variety of engineering and environmental problems for the urban setting. The only sole author, Dr Leucci, expressed deep gratitude in his acknowledgements to his team members who carried out substantial parts of the data acquisition. We are pleased to present this special issue to the engineering and environmental geophysics community and hope that it can serve as a snapshot of the current state-of-the-art studies in urban geophysics.

“It is no easy task to take a subject as obscure and technical as the determination of time and present it to the general public in a style which is at once humorous and rigorously correct” stated Alice Babcock of the U.S. Naval Observatory in nominating Joel Achenbach's article “Second Thoughts” for this year's Walter Sullivan Award for Excellence in Scientific Journalism. “Achenbach's article is the most engaging, in-depth, and accurate account that I have either read or heard on this subject,” Babcock said.Achenbach, a staff writer on The Miami Herald, received the Sullivan Award on May 31 at AGU's Spring meeting in Baltimore, Md. The award is given for a single article or radio/television report on geophysics, the study of Earth, or its environment in space. The judging panel included Walter Sullivan, New York Times; Athelstan Spilhaus, National Oceanic and Atmospheric Administration, (retired); Janet Luhmann, University of California, Los Angeles; Carl Sagan, Cornell University; Marilyn Suiter, American Geological Institute; and Carl Kisslinger, University of Colorado.

On Wednesday, June 13, lawmakers and their staffs jammed a Capitol Hill exhibit of research programs supported by the National Science Foundation (NSF). Sponsored by the Coalition for National Science Funding (CNSF), the exhibit is intended to demonstrate to members of Congress—who often wonder where the money they appropriate goes—the exciting research programs funded by NSF and their results.AGU joined with the American Geological Institute (AGI) in sponsoring an exhibit highlighting the Ocean Drilling Project (ODP). Frank Rack and Brecht Donoghue of the Joint Oceanographic Institutions (JOI) explained to interested legislators and congressional staff members that ODP is an international partnership of scientists and research institutions.
Building on informal meetings among a small group of scientific societies and research institutions concerned with climate science, AGU hosted a Leadership Summit on Climate Science Communication, 7-8 March 2011, in Washington, D. C. Presidents, executive directors, and senior public policy staff from 17 science organizations engaged with experts in the social sciences regarding effective communication of climate science and with practitioners from agriculture, energy, and the military. The keynote speaker for the summit was Bob Inglis, former U.S. representative from South Carolina's 4th Congressional District.
AGU members are invited to hear about the Union's new Scientific Integrity and Ethics Policy during a listening session at Fall Meeting. (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.
“A Flare to Remember.” “Starbucks for Starfish.” “Earth's Rotation Slows for El Niño.” What do these catchy headlines have in common? They all resulted from presentations at AGU's Spring Meeting in Boston, Mass. Yes, geophysical science can be big news when presented in a way that is interesting to general audiences.Proof? Well, the “Flare to Remember” headline (in the Dallas Morning News) reported the discovery, via the SOHO spacecraft, that a solar flare had produced, deep inside the Sun, seismic disturbances of a magnitude never experienced on Earth. Researchers Valentina Zharkova of Glasgow University and Alexander Kosovichev of Stanford gave media representatives a preview of their session, supported by visual aids, in the AGU press briefing room.

A primary function of Eos is to serve the geophysical community. It does this by publishing meeting announcements, book reviews, advertisements for jobs, scientific news items, and the like. Recent articles have helped the membership assess the stage of their careers (Eos, 60, 1024, 1979), informed them of the advantages of having names near the beginning of the alphabet (Eos, 59, 118, 1978), and helped them maximize information transfer during scientific meetings (Eos, 62, 179, 1981). However, no one has dealt with the very difficult problem of making papers memorable. Some techniques, such as long author lists, are now passé. Everyone is doing it. Other techniques, such as writing a very short paper or a humorous paper, are beyond the ken of most AGU members. Fortunately, there remains one technique that can be used by a surprisingly large number of AGU members.
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.
AGU journals continue to rank high in the 2012 Journal Citation Reports® (JCR), which was released by Thomson Reuters on 19 June. The impact factor of several AGU journals increased significantly, continuing their trend of the previous 5 years, while others remained consistent with the previous year's ranking.

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."

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).
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.
Of the many geophysical remote-sensing techniques available today, a few are suitable for the water ice-rich, layered material expected at the north martian ice cap. Radio echo sounding has been used for several decades to determine ice thickness and internal structure. Selection of operating frequency is a tradeoff between signal attenuation (which typically increases with frequency and ice temperature) and resolution (which is proportional to wavelength). Antenna configuration and size will be additional considerations for a mission to Mars. Several configurations for ice-penetrating radar systems are discussed: these include orbiter-borne sounders, sounding antennas trailed by balloons and penetrators, and lander-borne systems. Lander-borne systems could include short-wave systems capable of resolving fine structure and layering in the upper meters beneath the lander. Spread-spectrum and deconvolution techniques can be used to increase the depth capability of a radar system. If soundings over several locations are available (e.g., with balloons, rovers, or panning short-wave systems), then it will be easier to resolve internal layering, variations in basal reflection coefficient (from which material properties may be inferred), and the geometry of nonhorizontal features. Sonic sounding has a long history in oil and gas exploration. It is, however, unlikely that large explosive charges, or even swept-frequency techniques such as Vibroseis, would be suitable for a Polar lander -- these systems are capable of penetrating several kilometers of material at frequencies of 10-200 Hz, but the energy required to generate the sound waves is large and potentially destructive. The use of audio-frequency and ultrasonic sound generated by piezoelectric crystals is discussed as a possible method to explore layering and fine features in the upper meters of the ice cap. Appropriate choice of transducer(s) will permit operation over a range of fixed or modulated frequencies
Grove, T. L.
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.

The alpha-glucuronidase gene aguA from Aspergillus niger was cloned and characterised. Analysis of the promoter region of aguA revealed the presence of four putative binding sites for the major carbon catabolite repressor protein CREA and one putative binding site for the transcriptional activator XLNR. In addition, a sequence motif was detected which differed only in the last nucleotide from the XLNR consensus site. A construct in which part of the aguA coding region was deleted still resulted in production of a stable mRNA upon transformation of A. niger. The putative XLNR binding sites and two of the putative CREA binding sites were mutated individually in this construct and the effects on expression were examined in A. niger transformants. Northern analysis of the transformants revealed that the consensus XLNR site is not actually functional in the aguA promoter, whereas the sequence that diverges from the consensus at a single position is functional. This indicates that XLNR is also able to bind to the sequence GGCTAG, and the XLNR binding site consensus should therefore be changed to GGCTAR. Both CREA sites are functional, indicating that CREA has a strong influence on aguA expression. A detailed expression analysis of aguA in four genetic backgrounds revealed a second regulatory system involved in activation of aguA gene expression. This system responds to the presence of glucuronic and galacturonic acids, and is not dependent on XLNR.

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

The practice of limiting the shaker force in vibration tests was investigated at the NASA Jet Propulsion Laboratory (JPL) in 1990 after the mechanical failure of an aerospace component during a vibration test. Now force limiting is used in almost every major vibration test at JPL and in many vibration tests at NASA Goddard Space Flight Center (GSFC) and at many aerospace contractors. The basic ideas behind force limiting have been in the literature for several decades, but the piezo-electric force transducers necessary to conveniently implement force limiting have been available only in the last decade. In 1993, funding was obtained from the NASA headquarters Office of Chief Engineer to develop and document the technology needed to establish force limited vibration testing as a standard approach available to all NASA centers and aerospace contractors. This monograph is the final report on that effort and discusses the history, theory, and applications of the method in some detail.
AGU's Scientific Integrity and Professional Ethics policy, approved by the AGU Board of Directors and Council in December 2012, is now available online on a new Web site, http://ethics.agu.org. As the Web site states, the policy embodies a "set of guidelines for scientific integrity and professional ethics for the actions of the members and the governance of the Union in its internal activities; in its public persona; and most importantly, in the research and peer review processes of its scientific publications, its communications and outreach, and its scientific meetings."
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.

The title of this Forum is meant to sound paradoxical: Isn't the publication of results what AGU journals are for? I argue that in some ways they aren't, and suggest how to fix this. Explaining this apparent paradox requires that we look at the structure of a published paper and of the research project that produced it. Any project involves many steps; for those using data to examine some problem the first step (step A) is for researchers to collect the relevant raw data. Next (step B), they analyze these data to learn about some phenomenon of interest; this analysis is very often purely computational. Then (step C), the researchers (we can now call them "the authors") arrange the results of this analysis in a way that shows the reader the evidence for the conclusions of the paper. Sometimes these results appear as a table, but more often they are shown pictorially, as, for example, a plot of a time series, a map, a correlation plot, or a cross-section. Finally (step D), the authors state the conclusions to be drawn from the results presented.

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  Dennis Bazylinski (University of Nevada, Las Vegas),  Yuri Gorby (Craig Venter Institute),  Carlos Santamarina (Georgia Tech),  Susan Hubbard (Lawrence Berkeley Laboratory),  Roelof Versteeg (Idaho National Laboratory),  Eric Roden (University of Wisconsin),  George Luther (University of Delaware), and  Jinsong Chen (Lawrence Berkeley Laboratory)
We are in the midst of unprecedented change at the American Geophysical Union. Members have recently approved new bylaws to create a governance structure that better reflects the Union's diverse range of scientific interests and enables more efficient and transparent functioning of the organization. We have also embarked on a new strategic planning process to develop far-reaching organizational goals that will ensure continued global leadership in the Earth and space sciences. Finally, we are in the midst of hiring a new permanent executive director to lead our organization in the years ahead.

AGU is deeply committed to fostering the next generation of Earth and space scientists. Union activities contribute to this effort 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 AGU's annual Fall Meeting. GIFT allows K-12 science teachers to hear about the latest geoscience research from the scientists making the discoveries, explore new classroom resources for their students, and visit exhibits and technical sessions of the AGU meeting for free. In 2011 AGU worked with NESTA to develop an improved rigorous and open application process for scientists and education professionals who wished to work as a team and present their Earth and space science work to teachers, as well as lead the educators in a hands-on, classroom- ready activity. Twenty-four applications were received for five slots, so the selected presentations (on tsunamis, clouds, field campaigns, glaciers, and volcanoes), chosen through a peer- review process, truly represented the best ways of getting cutting-edge science into the classroom.
Geophysical Research Letters (GRL) and Journal of Geophysical Research-Atmospheres (JGR-D) both ranked among the top 10 of the most highly cited research publications on climate change over the past decade in a recent analysis by sciencewatch.com, an Internet tool published by the Thomson Reuters Web of Science® that tracks trends and performances in basic research. Although Nature and Science—the multidisciplinary heavyweights—led the field, GRL ranked fifth and JGR-D ranked sixth. The study was conducted by searching the Web of Science® database for terms such as “global warming,” “climate change,” “human impact,” and other key phrases in journal articles published and cited between 1999 and the spring of 2009. The analysis produced over 28,000 papers, from which sciencewatch.com identified the most cited institutions, authors, and journals.

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.

, climate dynamics, and in geodetic, hydrological, meteorological, oceanographic, seismological, and volcanological research. IUGG also places particular emphasis on the scientific problems of economically less-developed countries by sponsoring activities relevant to their scientific needs (e.g. Geosciences in Africa, Water Resources, Health and Well-Being etc.) The American Geophysical Union was established as the U.S. National Committee for IUGG in 1919 and today has become a distinguished union of individual geoscientists around the world. Several regional geoscience societies also evolved during the last several decades, most prominent being the European Geosciences Union and the Asia Oceania Geosciences Society. These, and some other national and regional geophysical societies, together with IUGG play a strong part in the international cooperation and promotion of geophysical sciences. At the same time the "geosciences" space is getting crowded, and there is a lot of overlap. International linkages between IUGG, AGU, EGU and other geophysical societies as well as their linkage with International Scientific Unions, that comprise the GeoUnions, are going to become more and more important. Working together is going to be more fruitful than territorial disputes. But what mechanisms can be used to encourage relationships between the international, national and regional geophysical and geoscientific bodies? We will discuss some possibilities on how to come together, to develop and to implement joint programs, research meeting, open forums, and policy statements.
Have you ever considered spending the summer as a science reporter in a mass media outlet or working for a member of Congress on Capitol Hill for a year? During a luncheon at the AGU Fall Meeting in San Francisco, learn about the AGU Congressional Science Fellowship and Mass Media Fellowship and how to apply for these opportunities. At the luncheon, this year's AGU Congressional Science Fellows, Rebecca French and Ian Lloyd, will discuss their experiences working in Congress. French, who received her Ph.D. in geosciences from Virginia Polytechnic Institute and State University, is working for Sen. Bernie Sanders (I-Vt.), while Lloyd, a recent Ph.D. graduate of Princeton, is working for Sen. Jeff Merkley (D-Oreg.). Over the next year, French and Lloyd will advise and assist the senators on some Earth science issues and other matters.

Geophysical imaging methods provide solutions to a wide variety of environmental and engineering problems: protection of soil and groundwater from contamination; disposal of chemical and nuclear waste; geotechnical site testing; landslide and ground subsidence hazard detection; location of archaeological artifacts. This book comprehensively describes the theory, data acquisition and interpretation of all of the principal techniques of geophysical surveying: gravity, magnetic, seismic, self-potential, resistivity, induced polarization, electromagnetic, ground-probing radar, radioactivity, geothermal, and geophysical borehole logging. Each chapter is supported by a large number of richly illustrated case histories. This book will prove to be a valuable textbook for senior undergraduates and postgraduates in environmental and applied geophysics, a supplementary course book for students of geology, engineering geophysics, civil and mining engineering, and a reference work for professional earth scientists, engineers and town planners.
INSPIRE is a European directive to harmonize spatial data in Europe. Its' aim is to establish a transparent, multidisciplinary network of environmental information by using international standards and OGC web services. Spatial data themes defined in the annex of the directive cover 34 domains that are closely bundled to environment and spatial information. According to the INSPIRE roadmap all data providers must setup discovery, viewing and download services and restructure data stores to provide spatial data as defined by the underlying specifications by 2014 December 1. More than 3000 institutions are going to be involved in the progress. During the data specification process geophysics as an inevitable source of geo information was introduced to Annex II Geology. Within the Geology theme Geophysics is divided into core and extended model. The core model contains specifications for legally binding data provisioning and is going to be part of the Implementation Rules of the INSPIRE directives. To minimize the work load of obligatory data transformations the scope of the core model is very limited and simple. It covers the most essential geophysical feature types that are relevant in economic and environmental context. To fully support the use cases identified by the stake holders the extended model was developed. It contains a wide range of spatial object types for geophysical measurements, processed and interpreted results, and wrapper classes to help data providers in using the Observation and Measurements (O&M) standard for geophysical data exchange. Instead of introducing the traditional concept of "geophysical methods" at a high structural level the data model classifies measurements and geophysical models based on their spatial characteristics. Measurements are classified as geophysical station (point), geophysical profile (curve) and geophysical swath (surface). Generic classes for processing results and interpretation models are curve model (1D), surface
Malone, T. F.
The Golden Age for geophysical research that followed the IGY set the stage for a new era of interaction among science, technology, and society. World population and the average economic productivity of individuals have both continued to grow exponentially during the past 50 years with the result that by the 1980s the demands of the human economy on the finite renewable resources of planet Earth were approximately equal to the natural regenerative capacities of planetary ecosystems. These demands are now "overshooting" those regenerative powers by about 20 per cent (1). The result could be a collapse in the life-supporting capacity of global ecosystems during coming decades, with tragic implications for civilized society. Novel modes of collaboration among all disciplines and all sectors of society are urgently needed to transform a potential catastrophe into the attractive vision that is now within reach as a result of rapidly expanding human knowledge, emerging technologies for sharing that knowledge (2), and the set of ethical principles for sustainable development contained in the Earth Charter (3). This prospect challenges geophysicists and scholars in all disciplines to forge a new and broadly based contract with society (4). 1. Wackernagel M. et al. 2002.

There is a paucity of information on the molecular biology of aging processes in the brain. We have used biomarkers of aging (SA β-Gal, p16Ink4a, Sirt5, Sirt6, and Sirt7) to demonstrate the presence of an accelerated aging phenotype across different brain regions in the AS/AGU rat, a spontaneous Parkinsonian mutant of PKCγ derived from a parental AS strain. P16INK4a expression was significantly higher in AS/AGU animals compared to age-matched AS controls (p < 0.001) and displayed segmental expression across various brain regions. The age-related expression of sirtuins similarly showed differences between strains and between brain regions. Our data clearly show segmental aging processes within the rat brain, and that these are accelerated in the AS/AGU mutant. The accelerated aging, Parkinsonian phenotype, and disruption to dopamine signalling in the basal ganglia in AS/AGU rats, suggests that this rat strain represents a useful model for studies of development and progression of Parkinson’s disease in the context of biological aging and may offer unique mechanistic insights into the biology of aging.

“Vladimìr Cermák, Director of the Geophysical Institute of the Czech Academy of Sciences in Prague, has for many years played a most remarkable role in bringing Earth scientists from the Eastern and Western Bloc countries together for scientific interactions. However anachronistic the concept of East and West political divisions may seem today, there are many who remember the nearly insuperable obstacles that prevented scientific exchange between those groups for decades prior to 1989. Vladimìr Cermák, through his organizing of small conferences and workshops in Czechoslovakia, accomplished the impossible. Through some extraordinarily deft diplomacy, Cermák obtained funding, secured visas, and mastered arcane currency regulations to enable small groups to meet in splendid castles and elegant country homes in rural Bohemia, facilities without urban distractions which had been placed under the custodianship of the Czech Academy of Science to serve as scientific retreats. Three meetings in the course of a decade stand out: at Liblice in 1982, and at Bechyne in 1987 and 1991, all dealing in general with heat flow and thermal aspects of lithospheric structure. These meetings were not just for prominent senior scientists, though of course many were in attendance. Of special significance were the opportunities for younger researchers to surmount the barriers that had been erected by forces well beyond the sphere of science. As one West German remarked as a graduate student in 1982, ‘I remember well how impressed I was…to learn the details of the daily personal and scientific life of an east German colleague of my own age.’ Cermák knew intuitively that the future belonged to the young, and he wanted to nurture their enthusiasm and stimulate their creativity.
The instrumentation development program was to proceed in parallel with scientific research and was driven by the needs of researchers. The development of these instruments has therefore included numerous geophysical field tests, many of which have resulted in the publication of scientific articles. This paper is a brief summary of some of the major geophysical instruments that have been developed and tested under the High Temperature Geophysics Program. These instruments are briefly described and references are given for further detailed information and for scientific papers that have resulted from the use of these instruments. 9 refs., 14 figs.
A fiber optic geophysical sensor is described in which laser light is passed through a sensor interferometer in contact with a geophysical event, and a reference interferometer not in contact with the geophysical event but in the same general environment as the sensor interferometer. In one embodiment, a single tunable laser provides the laser light. In another embodiment, separate tunable lasers are used for the sensor and reference interferometers. The invention can find such uses as monitoring for earthquakes, and the weighing of objects. 2 figures.
An introduction to geophysical methods used to explore for natural resources and to survey earth's geology is presented in this volume. It is suitable for second-and third-year undergraduate students majoring in geology or engineering and for professional engineering and for professional engineers and earth scientists without formal instruction in geophysics. The author assumes the reader is familiar with geometry, algebra, and trigonometry. Geophysical exploration includes seismic refraction and reflection surveying, electrical resistivity and electromagnetic field surveying, and geophysical well logging. Surveying operations are described in step-by-step procedures and are illustrated by practical examples. Computer-based methods of processing and interpreting data as well as geographical methods are introduced.

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.

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.

In the opinion of the undersigned, AGU's position statement regarding the conviction of Italian seismologists, issued following the 22 October 2012 conviction of six Italian scientists and one government official related to the 2009 L'Aquila earthquake (see Eos, 93(44), 444, 10.1029/2012EO440013), is absolutely right and correct. We believe that Franco Marenco's opinion disagreeing with AGU's position (Eos, 94(6), 63, doi:10.1002/2013EO060006) is misleading because it is based only on biased information gathered from the media. We invite Marenco and anyone who is interested in better understanding the L'Aquila trial and related issues to retrieve and read original documents and information from http://processoaquila.wordpress.com/.

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.
AGU will present the Edmond M. Dewan Scholarship for the first time at the 2014 Fall Meeting if the scholarship fund reaches the goal of $25,000 by the end of 2013.

Interactive teaching techniques encourage students to adopt an active role in their education and should therefore be used at different levels of the teaching sequence. In order to mitigate the lack of educational software for Applied Geophysics, a fully interactive graphic software has been developed. The program is written in Visual Basic with some subroutines in FORTRAN and is designed for IBM-PC microcomputers using a Windows environment. The program offers the majority of the processes involved in geophysical data handling, modelling, tutorials, and instrument simulators.
What does it take to create a science video that engages the audience and draws thousands of views on YouTube? Those interested in finding out should submit their research-related videos to AGU's Fall Meeting science film analysis workshop, led by oceanographer turned documentary director Randy Olson. Olson, writer-director of two films (Flock of Dodos: The Evolution-Intelligent Design Circus and Sizzle: A Global Warming Comedy) and author of the book Don't Be Such a Scientist: Talking Substance in an Age of Style, will provide constructive criticism on 10 selected video submissions, followed by moderated discussion with the audience. To submit your science video (5 minutes or shorter), post it on YouTube and send the link to the workshop coordinator, Maria-José Viñas (email@example.com), with the following subject line: Video submission for Olson workshop. AGU will be accepting submissions from researchers and media officers of scientific institutions until 6:00 P.M. eastern time on Friday, 4 November. Those whose videos are selected to be screened will be notified by Friday, 18 November. All are welcome to attend the workshop at the Fall Meeting.
The National Toxicology Program conducted a cancer evaluation on cumene for possible listing in the Report on Carcinogens (RoC). The cancer evaluation is captured in the RoC monograph, which was peer reviewed in a public forum. The monograph consists of two components: (Part 1) the cancer evaluation, which reviews the relevant scientific information, assesses its quality, applies the RoC listing criteria to the scientific information, and provides the NTP recommendation for listing status for cumene in the RoC, and (Part 2) the substance profile proposed for the RoC, containing the NTP's listing status recommendation, a summary of the scientific evidence considered key to reaching that decision, and data on properties, use, production, exposure, and Federal regulations and guidelines to reduce exposure to cumene. This monograph provides an assessment of the available scientific information on cumene, including human exposure and properties, disposition and toxicokinetics, cancer studies in experimental animals, and studies of mechanisms and other related effects, including relevant toxicological effects, genetic toxicology, and mechanisms of carcinogenicity. From this assessment, the NTP recommended that cumene be listed as reasonably anticipated to be a human carcinogen in the RoC based on sufficient evidence from studies in experimental animals, which found that cumene exposure caused lung tumors in male and female mice and liver tumors in female mice. Several proposed mechanisms of carcinogenesis support the relevance to humans of the lung and liver tumors observed in experimental animals. Specifically, there is evidence that humans and experimental animals metabolize cumene through similar metabolic pathways. In addition, mutations of the K-ras oncogene and p53 tumor-suppressor gene observed in cumene-induced lung tumors in mice, along with altered expression of many other genes, resemble molecular alterations found in human lung and other cancers.

The monograph consists of two components: (Part 1) the cancer evaluation, which reviews the relevant scientific information, assesses its quality, applies the RoC listing criteria to the scientific information, and provides the NTP recommendation for listing status for 1 bromopropane in the RoC, and (Part 2) the substance profile proposed for the RoC, containing the NTP's listing status recommendation, a summary of the scientific evidence considered key to reaching that decision, and data on properties, use, production, exposure, and Federal regulations and guidelines to reduce exposure to 1-bromopropane. This monograph provides an assessment of the available scientific information on 1 bromopropane, including human exposure and properties, disposition and toxicokinetics, cancer studies in experimental animals, and studies of mechanisms and other related effects, including relevant toxicological effects, genetic toxicology, and mechanisms of carcinogenicity. From this assessment, the NTP recommended that 1 bromopropane be listed as reasonably anticipated to be a human carcinogen in the RoC based on sufficient evidence from studies in experimental animals, which found inhalation exposure to 1-bromopropane caused skin tumors in male rats, large intestine tumors in female and male rats, and lung tumors in female mice. Also noted was that 1 bromopropane, either directly or via reactive metabolites, caused molecular alterations that typically are associated with carcinogenesis, including genotoxicity, oxidative stress, and glutathione depletion. These alterations, observed in mainly in vitro and toxicity studies in rodents, are relevant to possible mechanisms of human carcinogenicity and support the relevance of the cancer studies in

Timely publication of manuscripts is important to authors and readers. AGU has significantly accelerated both the review and production processes for the Journal of Geophysical Research-Atmospheres (JGR-Atmospheres). Via a number of mechanisms (e.g., shortening the time allotted for reviewer selection, manuscript reviews, and revisions), the mean time to first decision has been decreased from 98 days in 2007 to 50 days in 2011, and the mean time to final decision has been decreased from 132 days in 2007 to 71 days in 2011. By implementing a new content management system, adjusting the workflow for improved efficiency, requesting authors to proofread their manuscripts quicker, and improving monitoring and follow-up to author and vendor queries, the mean production time from manuscript acceptance to publication has been decreased from 128 days in 2010 to only 56 days in 2012. Thus, in the past few years the mean time to publication of JGR-Atmospheres has been cut in half. These milestones have been achieved with no loss of quality of presentation or content. In addition, online posting of "papers in press" on JGR-Atmosphere's home page typically occurs within a few days after acceptance. JGR-Atmospheres editors thank manuscript reviewers, authors, and AGU staff who have greatly contributed to the more timely review and publication processes. This information will be updated periodically on the JGR-Atmospheres home page. A chart showing the average time from acceptance to publication for all of AGU's journals is available at http://www.agu.org/pubs/pdf/31May2012_Timeliness_Chart.pdf.

Terrestrial planet geophysics beyond our home sphere had its start arguably in the early 1960s, with Keith Runcorn contending that the second-degree shape of the Moon is due to convection and Mariner 2 flying past Venus and detecting no planetary magnetic field. Within a decade, in situ surface geophysical measurements were carried out on the Moon with the Apollo program, portions of the lunar magnetic and gravity fields were mapped, and Jack Lorell and his colleagues at JPL were producing spherical harmonic gravity field models for Mars using tracking data from Mariner 9, the first spacecraft to orbit another planet. Moreover, Mariner 10 discovered a planetary magnetic field at Mercury, and a young Sean Solomon was using geological evidence of surface contraction to constrain the thermal evolution of the innermost planet. In situ geophysical experiments (such as seismic networks) were essentially never carried out after Apollo, although they were sometimes planned just beyond the believability horizon in planetary mission queues. Over the last three decades, the discipline of terrestrial planet geophysics has matured, making the most out of orbital magnetic and gravity field data, altimetric measurements of surface topography, and the integration of geochemical information. Powerful constraints are provided by tectonic and volcanic information gleaned from surface images, and the engagement of geologists in geophysical exercises is actually quite useful. Accompanying these endeavors, modeling techniques, largely adopted from the Earth Science community, have become increasingly sophisticated and have been greatly enhanced by the dramatic increase in computing power over the last two decades. The future looks bright with exciting new data sets emerging from the MESSENGER mission to Mercury, the promise of the GRAIL gravity mission to the Moon, and the re-emergence of Venus as a worthy target for exploration. Who knows? With the unflagging optimism and persistence

The regolith-covered surfaces of asteroids preserve records of geophysical processes that have occurred both at their surfaces and sometimes also in their interiors. As a result of the unique microgravity environment that these bodies possess, a complex and varied geophysics has given birth to fascinating features that we are just now beginning to understand. The processes that formed such features were first hypothesized through detailed spacecraft observations and have been further studied using theoretical, numerical, and experimental methods that often combine several scientific disciplines. These multiple approaches are now merging toward a further understanding of the geophysical states of the surfaces of asteroids. In this chapter we provide a concise summary of what the scientific community has learned so far about the surfaces of these small planetary bodies and the processes that have shaped them. We also discuss the state of the art in terms of experimental techniques and numerical simulations that are currently being used to investigate regolith processes occurring on small-body surfaces and that are contributing to the interpretation of observations and the design of future space missions.
In fall 2009, AGU launched a member-driven pilot project to improve the accuracy of climate science coverage in the media and to improve public understanding of climate science. The project's goal was to increase the accessibility of climate science experts to journalists across the full spectrum of media outlets. As a supplement to the traditional one-to-one journalist-expert relationship model, the project tested the novel approach of providing a question-and-answer (Q&A) service with a pool of expert scientists and a Web-based interface with journalists. Questions were explicitly limited to climate science to maintain a nonadvocacy, nonpartisan perspective.
I am pleased to announce that AGU has taken another step in our effort to build strategic alliances with partner groups by signing a memorandum of agreement with the Soil Science Society of America (SSSA). This agreement is based on the common interests of our members and will allow us to strengthen our respective organizations by Exchanging information on key programs and initiatives.Expanding membership of both our organizations through possible joint programs.>Exchanging information and possible joint activities concerning educational opportunities, student programs, and professional services.Exchanging information and possible co-organization of scientific conferences.

The session that this poster is in, the: "Self-made sensors and unintended use of measurement equipment", also known as the "MacGyver-session" has had 7 years of scientists contributing their self made devices, hacks and solutions with the hydrological community. In 2009, the first session was held at the AGU fall meeting and since 2011 a session is also organised at the EGU General Assembly. 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.

We previously reported the synthesis of gadolinium-based nanoparticles (NPs) denoted AGuIX (activation and guiding of irradiation by X-ray) NPs and demonstrated their potential as an MRI contrast agent and their efficacy as radiosensitizing particles during X-ray cancer treatment. Here we focus on the elimination kinetics of AGuIX NPs from the subcellular to whole-organ scale using original and complementary methods such as laser-induced breakdown spectroscopy (LIBS), intravital two-photon microscopy, inductively coupled plasma optical emission spectrometry (ICP-OES), transmission electron microscopy (TEM), and electrospray ionization mass spectrometry (ESI-MS). This combination of techniques allows the exact mechanism of AGuIX NPs elimination to be elucidated, including their retention in proximal tubules and their excretion as degraded or native NPs. Finally, we demonstrated that systemic AGuIX NP administration induced moderate and transient effects on renal function. These results provide useful and promising preclinical information concerning the safety of theranostic AGuIX NPs.
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.

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.

Demographers use population pyramids to characterize the age/gender structure of societal groups. Diagrams of the population of age cohorts for both sexes assume the shape of a pyramid in rapidly expanding groups, having many more young people than older adults. Stable populations have similar numbers of people in age cohorts from infants through middle-age adults. Shrinking populations have fewer children and relatively larger numbers of adults. Demographic analysis of the American Geophysical Union's (AGU) membership reveals significant differences among the numerous specialties and the membership as a whole. The population structure diagram of the total AGU membership is highly asymmetrical with 77.5% male and 22.5% female. Males outnumber females in every age cohort. This is most noticeable among members born prior to 1945. Males belonging to these cohorts make up 16.5% of the total membership, while female members of equivalent age include 0.8% of the total. The largest membership cohort (29% of the total) is comprised of males born between 1950 and 1964, a group that includes both the "baby boom" generation and post-war petroleum exploration expansion. In contrast, the female cohort with birth years from 1970 to 1979 is the largest grouping of women members (8.4% of AGU's membership). Furthermore, women comprise 36% of the members born since 1965, and only 14.5% of those born before 1965. Considered separately, the female membership's age structure is characteristic of a growing population, while the male side is in relative decline. The population structure of the entire membership is mirrored in some specialties, but there are remarkable differences in others. The largest specialty group (hydrology) includes 16.9% of the total AGU membership and has a population structure that differs little from that of the whole organization. Four specialties, Atmospheric Chemistry, Biogeosciences, and Paleoceanography and Paleoclimatology, and Marine Geochemistry differ

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

Ten years have passed since Directive 2004/24/EC regulating herbal medicinal products across the EU were published. The directive created the Committee on Herbal Medicinal Products within the European Medicines Agency whose remit includes the creation and publishing of official EU monographs on herbal medicinal products. These monographs include the official uses of the products and their evidence for efficacy and safety. To this effect, we are interested in analysing the potential impact herbal product EU monographs could have on the therapeutic treatment options available for prescribers in Malta. Therefore our aim was two-fold. First, to rationalise the spread of indications of the herbal substances listed in the community herbal monograph inventory and subsequently determine if these herbal substances could potentially contribute to the treatment options available in our local scenario (Malta). 128 EU monographs were analysed resulting in a total of 230 indications which subsequently codified into 42 unique ATC codes. The Malta Medicines List contains 1456 unique ATC codes. Comparative analysis of the Malta Medicines List revealed that the 21 therapeutic areas had 4 or less pharmaceutically used substances (5th level ATC codes) registered and therefore in our opinion are areas with limited therapeutic choice. The following 4 therapeutic areas, A05 bile and liver therapy, A13 tonics, A15 appetite stimulants and D03 preparations for treatment of wounds and ulcers, could potentially benefit from the registration of herbal medicinal products according to the EU herbal monographs. If such registration is effected the aforementioned areas would no longer be considered limited because more than 4 therapeutic choices would be available to prescribers. This study is the first study across the EU to analyse the potential impact of published EU herbal monographs on therapeutic coverage in an EU member state and confirms the notion that herbal products could potentially

In the past 8 years, since Pedlosky's book was first published, it has found a well established place in the literature of dynamical meteorology and physical oceanography. Geophysicists less familiar with these fields may need to be reminded that the subject of geophysical fluid dynamics, in the narrow definition used in the title of the book, refers to the theory of the large-scale motions of the atmosphere and the oceans. Topics such as thermal convection in the atmosphere or in Earth's mantle and core are not treated in this book, and the reader will search in vain for a discussion of atmospheric or oceanic tides. The theory of quasi-geostrophic flow is described comprehensively, however, and its major applications to problems of atmospheric and oceanic circulations are considered in detail.

A set of spherical sampling functions is defined such that they are related to spherical-harmonic functions in the same way that the sampling functions of information theory are related to sine and cosine functions. An orderly distribution of (N + 1) squared sampling points on a sphere is given, for which the (N + 1) squared spherical sampling functions span the same linear manifold as do the spherical-harmonic functions through degree N. The transformations between the spherical sampling functions and the spherical-harmonic functions are given by recurrence relations. The spherical sampling functions of two arguments are extended to three arguments and to nonspherical reference surfaces. Typical applications of this formalism to geophysical topics are sketched.

A physical model of Mars is presented on the basis of light-scattering observations of the Martian atmosphere and surface and interior data obtained from observations of the geopotential field. A general description of the atmosphere is presented, with attention given to the circulation and the various cloud types, and data and questions on the blue haze-clearing effect and the seasonal darkening wave are summarized and the Mie scattering model developed to explain these observations is presented. The appearance of the planet from earth and spacecraft through Mariner 9 is considered, and attention is given to the preparation of topographical contour maps, the canal problem and large-scale lineaments observed from Mariner 9, the gravity field and shape of the planet and the application of Runcorn's geoid/convection theory to Mars. Finally, a summary of Viking results is presented and their application to the understanding of Martian geophysics is discussed.

Childhood stage is indispensable in the education of human beings and especially critical to arise scientific interest in children. We discuss the participatory design of a didactic videogame, i.e. a "serious" game to teach geophysics and Earth sciences to high and low-school students. Geophysics is the application of the laws and techniques of physics to uncover knowledge about the earth's dynamic processes and subsurface structure. It explores phenomena such as earthquakes, volcanoes, tsunamis to improve our understanding of the earth's physical processes and our ability to predict reoccurrences. Effective mitigation of risks from catastrophic geologic hazards requires knowledge and understanding of local geology and geologic processes. Scientific outreach can be defined as discourse activity, whose main objective is to communicate some knowledge previously produced in scientific contexts to a non-expert massive audience. One of the difficulties science educators need to overcome is to explain specific concepts from a given discipline in a language simple and understandable for their audience. Digital games today play a large role in young people's lives. Games are directly connected to the life of today's adolescents. Therefore, digital games should be included and broached as a subject in the classroom. The ardor and enthusiasm that digital games evoke in teenagers has indeed brought many researchers, school leaders and teachers to the question "how video games" can be used to engage young people and support their learning inside the classroom. Additionally, studies have shown that digital games can enhance various skills such as the ability to concentrate, stamina, tactical aptness, anticipatory thinking, orientation in virtual spaces, and deductive reasoning. Thus, videogames become an effective didactic mechanism and should have a place in the classroom. The project aims to explore the potentials of entertainment technologies in educational processes

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.
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.
The Ocean Sciences Section has selected four students to receive Best Student Paper Awards for the 1988 Joint AGU and American Society for Limnology and Oceanography (ASLO) Meeting held last January in New Orleans.Brad M. Bebout received a Best Student Paper Award for his paper “The Use of Agricultural Waste (Corn Slash) to Support Microzone-Associated Nitrogen Fixation by Marine Microorganisms.” Bebout is an M.S. candidate in marine sciences at the University of North Carolina at Chapel Hill. 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.

Two major glycoasparagines (2-acetamido-N-(4'-L-aspartyl)-2-deoxy-beta-D-glycosylamines) were isolated from the urine of patients with aspartylglycosylaminuria (AGU). They were composed of equimolar amounts of sialic acid, galactose, glucosamine, and aspartic acid. They were isomeric with respect to the position of sialic acid attachment, since they produced the same glycoasparagine on incubation with the neuraminidase from Clostridium perfringens. The structure of the resulting sialic acid-free glycoasparagine was determined as beta-Gal-(1 leads to 4)-beta-GlcNAc-Asn based on the following findings. It produced galactose on incubation with beta-galactosidase, and N-acetyllactosamine and aspartic acid on incubation with 4-L-aspartylglycosylamine amindo hydrolase.
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.

If Ceres formed as an ice-rich body, as suggested by its low density and the detection of ammoniated phyllosilicates , then it should have differentiated an ice-dominated shell, analogous to large icy satellites . Instead, Dawn observations revealed an enrichment of Ceres' shell in strong materials, either a rocky component and/or salts and gas hydrates [3, 4, 5, 6]. We have explored several scenarios for the emplacement of Ceres' surface. Endogenic processes cannot account for its overall homogeneity. Instead we suggest that Ceres differentiated an icy shell upon freezing of its early ocean that was removed as a consequence of frequent exposure by impacting after the dwarf planet migrated from a cold accretional environment to the warmer outer main belt (or when the solar nebula dissipated, if Ceres formed in situ). This scenario implies that Ceres' current surface represents the interface between the original ice shell and the top of the frozen ocean, a region that is extremely rich chemistry-wise, as illustrated by the mineralogical observations returned by Dawn . Thermal modeling shows that the shell could remain warm over the long term and offer a setting for the generation of brines that may be responsible for the emplacement of Ahuna Mons  and Occator's bright spots  on an otherwise homogeneous surface . An important implication is that Ceres' surface offers an analog for better understanding the deep interior and chemical evolution of large ice-rich bodies.References:  De Sanctis et al., Nature, 2015;  McCord and Sotin, Journal of Geophysical Research, 2005;  Park et al., Nature, 2016 (in press);  Hiesinger et al., Science (submitted);  Bland et al., Nature Geoscience, 2016 (in press);  Fu et al., AGU Fall Meeting, 2015  De Sanctis et al., Nature, 2016 (in press);  Ruesch et al., Science, in revision;  Ammannito et al., Science, 2016 (accepted).Acknowledgements: Part of this work is being carried out at the Jet
This monograph examines a new military mission-peace-enforcement. It does so through a five part strategic process that links national interests and national security strategy to tactical operations. it asserts that US national security strategy is evolving as a result of the end of the Cold War and that a new strategy will lead to new military missions. The monograph first describes a limited spectrum of military operations that comprise a peace-enforcement mission. Next, it reviews enduring US national interests then analyzes evolving national security strategy to determine if these elements of strategy support the need for a peace-enforcement mission. The monograph then examines national military strategy, operational level strategy and joint guidance, and finally, US tactical doctrine to determine if peace-enforcement is a mission the US military can execute today. The monograph concludes that national interests and evolving national security strategy will emphasize promotion of democracy and stability in lieu of Cold War deterrence. The national military strategy partially supports this shift; support should increase as the Clinton administration clarifies its policy and solidifies the shift from containment. Lastly, the monograph finds there is sufficient operational and tactical level guidance to conduct the mission and recommends formal acceptance of the peace-enforcement mission into joint doctrine.

The easily recognised genus Otidea is subjected to numerous problems in species identification. A number of old names have undergone various interpretations, materials from different continents have not been compared and misidentifications occur commonly. In this context, Otidea is monographed, based on our multiple gene phylogenies assessing species boundaries and comparative morphological characters (see Hansen & Olariaga 2015). All names combined in or synonymised with Otidea are dealt with. Thirty-three species are treated, with full descriptions and colour illustrations provided for 25 of these. Five new species are described, viz. O. borealis, O. brunneoparva, O. oregonensis, O. pseudoleporina and O. subformicarum. Otidea cantharella var. minor and O. onotica var. brevispora are elevated to species rank. Otideopsis kaushalii is combined in the genus Otidea. A key to the species of Otidea is given. An LSU dataset containing 167 sequences (with 44 newly generated in this study) is analysed to place collections and determine whether the named Otidea sequences in GenBank were identified correctly. Fourty-nine new ITS sequences were generated in this study. The ITS region is too variable to align across Otidea, but had low intraspecific variation and it aided in species identifications. Thirty type collections were studied, and ITS and LSU sequences are provided for 12 of these. A neotype is designated for O. cantharella and epitypes for O. concinna, O. leporina and O. onotica, along with several lectotypifications. The apothecial colour and shape, and spore characters are important for species identification. We conclude that to distinguish closely related or morphologically similar species, a combination of additional features are needed, i.e. the shape of the paraphyses, ectal excipulum structure, types of ectal excipulum resinous exudates and their reactions in Melzer's reagent and KOH, tomentum and basal mycelium colours and exudates. The KOH reaction of

Searching by subject for monographic information online in the medical literature is a challenging task. The NLM database of choice is CATLINE. Other NLM databases of interest are BIOTHICSLINE, CANCERLIT, HEALTH, POPLINE, and TOXLINE. Ten BRS databases are also discussed. Of these, Books in Print, Bookinfo, and OCLC are explored further. The databases are compared as to number of total records and number and percentage of monographs. Three topics were searched on CROSS to compare hits on BBIP, BOOK, and OCLC. The same searches were run on CATLINE. The parameters of time coverage and language were equalized and the resulting citations were compared and analyzed for duplication and uniqueness. With the input of CATLINE tapes into OCLC, OCLC has become the database of choice for searching by subject for medical monographs.

Jesuits have had ah interest in observing and explaining geophysical phenomena since this religious order, the Society of Jesus, was founded by Ignatius of Loyola in 1540. Three principal factors contributed to this interest: their educational work in colleges and universities, their missionary endeavors to remote lands where they observed interesting and often as yet undocumented natural phenomena, and a network of communication that brought research of other Jesuits readily to their awareness.One of the first and most important Jesuit colleges was the Roman College (today the Gregorian University) founded in 1551 in Rome, which served as a model for many other universities throughout the world. By 1572, Christopher Clavius (1537-1612), professor of mathematics at the Roman College, had already initiated an important tradition of Jesuit research by emphasizing applied mathematics and insisting on the need of serious study of mathematics in the program of studies in the humanities. In 1547 he directed a publication of Euclid's work with commentaries, and published several treatises on mathematics, including Arithmetica Practica , Gnomonicae , and Geometrica Practica . Clavius was also a Copernican and supported his friend Galileo when he announced the discovery of the satellites of Jupiter.
In 1993, I tested a radio-controlled airplane designed by Jim Walker of Brigham Young University for low-elevation aerial photography. Model-air photography retains most of the advantages of standard aerial photography --- the photographs can be used to detect lineaments, to map roads and buildings, and to construct stereo pairs to measure topography --- and it is far less expensive. Proven applications on the Oak Ridge Reservation include: updating older aerial records to document new construction; using repeated overflights of the same area to capture seasonal changes in vegetation and the effects of major storms; and detecting waste trench boundaries from the color and character of the overlying grass. Aerial photography is only one of many possible applications of radio-controlled aircraft. Currently, I am funded by the Department of Energy`s Office of Technology Development to review the state of the art in microavionics, both military and civilian, to determine ways this emerging technology can be used for environmental site characterization. Being particularly interested in geophysical applications, I am also collaborating with electrical engineers at Oak Ridge National Laboratory to design a model plane that will carry a 3-component flux-gate magnetometer and a global positioning system, which I hope to test in the spring of 1994.

The broad objective of this work is to improve understanding of the internal structures and thermal and stress histories of the solid planets by combining results from analytical and computational modeling, and geophysical data analysis of gravity, topography and tectonic surface structures. During the past year we performed two quite independent studies in the attempt to explain the Mariner 10 magnetic observations of Mercury. In the first we revisited the possibility of crustal remanence by studying the conditions under which one could break symmetry inherent in Runcorn's model of a uniformly magnetized shell to produce a remanent signal with a dipolar form. In the second we applied a thin shell dynamo model to evaluate the range of intensity/structure for which such a planetary configuration can produce a dipole field consistent with Mariner 10 results. In the next full proposal cycle we will: (1) develop numerical and analytical and models of thin shell dynamos to address the possible nature of Mercury s present-day magnetic field and the demise of Mars magnetic field; (2) study the effect of degree-1 mantle convection on a core dynamo as relevant to the early magnetic field of Mars; (3) develop models of how the deep mantles of terrestrial planets are perturbed by large impacts and address the consequences for mantle evolution; (4) study the structure, compensation, state of stress, and viscous relaxation of lunar basins, and address implications for the Moon s state of stress and thermal history by modeling and gravity/topography analysis; and (5) use a three-dimensional viscous relaxation model for a planet with generalized vertical viscosity distribution to study the degree-two components of the Moon's topography and gravity fields to constrain the primordial stress state and spatial heterogeneity of the crust and mantle.

A fundamental part of geophysics is to make inferences about the interior of the earth on the basis of data collected at or near the surface of the earth. In almost all cases these measured data are only indirectly related to the properties of the earth that are of interest, so an inverse problem must be solved in order to obtain estimates of the physical properties within the earth. In February of 1999 the U.S. Department of Energy sponsored a workshop that was intended to examine the methods currently being used to solve geophysical inverse problems and to consider what new approaches should be explored in the future. The interdisciplinary area between inverse problems in geophysics and optimization methods in mathematics was specifically targeted as one where an interchange of ideas was likely to be fruitful. Thus about half of the participants were actively involved in solving geophysical inverse problems and about half were actively involved in research on general optimization methods. This report presents some of the topics that were explored at the workshop and the conclusions that were reached. In general, the objective of a geophysical inverse problem is to find an earth model, described by a set of physical parameters, that is consistent with the observational data. It is usually assumed that the forward problem, that of calculating simulated data for an earth model, is well enough understood so that reasonably accurate synthetic data can be generated for an arbitrary model. The inverse problem is then posed as an optimization problem, where the function to be optimized is variously called the objective function, misfit function, or fitness function. The objective function is typically some measure of the difference between observational data and synthetic data calculated for a trial model. However, because of incomplete and inaccurate data, the objective function often incorporates some additional form of regularization, such as a measure of smoothness

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

Purpose: AGuIX are gadolinium-based nanoparticles, initially developed for MRI, that have a potential role in radiation therapy as a radiosensitizer. Our goal is to demonstrate that these nanoparticles can both be used as an MRI contrast agent, as well as to obtain local dose enhancement in a pancreatic tumor when delivered in combination with an external beam irradiation. Methods: We performed in vitro cell uptake and radiosensitization studies of a pancreatic cancer cell line in a low energy (220kVp) beam, a standard clinical 6MV beam (STD) and a flattening filter free clinical 6MV beam (FFF). After injection of 40mM of nanoparticles, a biodistribution study was performed in vivo on mice with subcutaneous xenograft pancreatic tumors. In vivo radiation therapy studies were performed at the time point of maximum tumor uptake. Results: The concentration of AGuIX nanoparticles in Panc-1 pancreatic cancer cells, determined in vitro by MRI and ICPMS, peaks after 30 minutes with 0.3% of the initial concentration (5mg/g). Clonogenic assays show a significant effect (p<0.05) when the AGuIX are coupled with MV photon irradiation (DEF20%=1.31). Similar AGuIX tumor uptake is found in vivo by both MRI and ICPMS 30 minutes after intravenous injection. For long term survival studies, the choice of the radiation dose is determined with 5 control groups (3mice/group) irradiated with 0, 5, 10, 15, and 20Gy. Afterwards, 4 groups (8mice/group) are used to evaluate the effect of the nanoparticles. A Logrank test is performed as a statistical test to evaluate the effect of the nanoparticles. Conclusion: The combination of the MRI contrast and radiosensitization properties of gadolinium nanoparticles reveals a strong potential for usage with MRI-guided radiation therapy.

Technical refinement of boar sperm cryopreservation is indispensable for effective breeding of the rare Okinawan native pig, the Agu. The objective of the present study was to determine whether addition of low-density lipoprotein (LDL) extracted from hen egg yolk to the freezing extender improves the characteristics of cryopreserved Agu spermatozoa. Ejaculated Agu sperm frozen in extender supplemented with 2, 4, 6, 8 or 10% LDL instead of egg yolk was thawed, and the post-thaw sperm characteristics were evaluated. Treatment with 4-8% LDL during cooling and freezing significantly increased the intracellular cholesterol content, as compared to that of sperm frozen in extender containing 20% egg yolk (P<0.05). Higher potential resistance to cell damage from cryoinjury was also observed in sperm frozen in extender supplemented with LDL: the integrities of plasmalemma and DNA, mitochondrial activity and proteolytic activity of the acrosomal content in the post-thaw sperm were superior to those of sperm that were not treated with LDL. Moreover, the percentages of total motile sperm and the extent of rapid progressive motility at 1 and 3 h after incubation were markedly higher in sperm treated with 4 or 6% LDL, and these sperm also had more ATP. However, LDL did not inhibit in vitro sperm penetrability, even though the cholesterol content of post-thaw sperm was higher after treatment with LDL. These findings indicate that addition of 4-6% LDL instead of egg yolk to the freezing extender improves the post-thaw characteristics of Agu sperm by protecting sperm against cold shock damage during cryopreservation.

Significant change occurred in the demographic properties of the American Geophysical Union membership during the period April 2006- January 2010. During this period AGU membership decreased from 48,332 to 38,847, a drop of 19.6%. Most of the change appears to have been driven by the aging membership of the Union, especially in the United States, and the effects of the global economic crisis on employment in all sectors of economy. Of the 38,847 members in January 2010, data on the birth year and gender were available for 33,610 members including 21,567 who reside in the United States. These data were compared to a similar data set captured in April 2006. The following observations are based on this subset of the total AGU membership for who country of residence and both age and gender are known. The number of AGU members residing in the United States decreased by 18.6% during the study period. As should be expected, the changes were not spread evenly between the genders or across birth-year cohorts. Membership among males decreased by 19%, while there were 17% fewer female members. The female cohorts that experienced the greatest losses were those including women from 30-40 years old (born 1970-1979). These data appear to echo multiple studies that show women leaving the sciences for gender-specific reasons. For the purposes of this analysis, the birth-year cohorts are divided into three groups. Members born prior to 1945 compose the oldest cohort. The Baby-Boom generation includes members born between 1945 and 1964. The youngest group includes members born from 1965 onward. Because of the very small number of women in the oldest group (only 4.7%) most of the change occurred among males. The total membership loss from this group was 1,140 members, 23% of the total. The largest change occurred among Baby Boomers. The group decreased by 2,760 members, accounting for 56% of the total decline in membership among US residents. Males accounted for most of the change (2

It is critical to recognize the benefits and limitations of scientific knowledge, particularly when it comes to predicting hazards. I agree with G. J. Wasserburg that AGU should help scientists communicate their work accurately and understandably so it can provide the greatest value to society. This objective is explicit in AGU's new strategic plan (http://www.agu.org/about/strategic_plan.shtml) and is consistent with our vision of both advancing and communicating Earth and space science to ensure a sustainable future. We as a community have an obligation to increase the role of science in informing policy to mitigate the impacts of natural disasters. Such efforts require an open exchange of ideas and information and a clear understanding of the limitations of our knowledge. In response to Flavio Dobran, I agree that scientists are not above the law and, like all citizens, must be held accountable for their actions. However, laws and lawmakers must also recognize what science can and cannot do. We cannot yet reliably predict precisely when earthquakes will occur.

The increasing world demand and record-high costs for energy and mineral resources, along with the attendant environmental and climate concerns, have escalated the need for trained geophysicists to unprecedented levels. This is not only a national need; it's a critical global need. As Earth scientists and educators we must seriously ask if our geophysics pipeline can adequately address this crisis. One program that has helped to answer this question in the affirmative for 25 years is SAGE (Summer of Applied Geophysical Experience). SAGE continues to develop with new faculty, new collaborations, and additional ways to support student participation during and after SAGE. ?? 2008 Society of Exploration Geophysicists.

Object storage systems (such as Amazon S3 or Ceph) have been shown to be cost-effective and highly scalable for data repositories in the Petabyte range and larger. However traditionally data storage used for geophysical software systems has centered on file-based systems and libraries such as NetCDF and HDF5. In this session we'll discuss the advantages and challenges of moving to an object store-based model for geophysical data. We'll review a proposed model for a geophysical data service that provides an API-compatible library for traditional NetCDF and HDF5 applications while providing high scalability and performance. One further advantage of this approach is that any dataset or dataset selection can be referenced as a URI. By using versioning, the data the URI references can be guaranteed to be unmodified, thus enabling reproducibility of referenced data.
This book develops an integrated and balanced picture of present knowledge of the continental crust. Crust and lithosphere are first defined, and the formation of crusts as a general planetary phenomenon is described. The background and methods of geophysical studies of the earth's crust and the collection of related geophysical parameters are examined. Creep and friction experiments and the various methods of radiometric age dating are addressed, and geophysical and geological investigations of the crustal structure in various age provinces of the continents are studied. Specific tectonic structures such as rifts, continental margins, and geothermal areas are discussed. Finally, an attempt is made to give a comprehensive view of the evolution of the continental crust and to collect and develop arguments for crustal accretion and recycling. 647 references.

PURPOSE: To test three related hypotheses about monographs circulation at academic health sciences libraries: (1) Juran's "Vital Few" Principle, sometimes incorrectly referred to as the "Pareto Principle"; (2) most (> 30%) new monographs will not circulate within four years; and, (3) Trueswell's 20/80 rule concerning intensity of monographs circulation. METHODS: Retrospective circulation study conducted at a major academic health sciences library in November 1997 on monographs acquired during 1993, utilizing an online review file. RESULTS: Unexpectedly, most monographs (84%) had circulated at least once in the four years following acquisition. Combining circulation and in-house data revealed that 90.7% of the monographs acquired in 1993 had been used at least once. Small percentages of these monographs produced disproportionately high circulation levels. CONCLUSION: Monographs circulation rates confirm Juran's Vital Few principle. Most monographs circulated at least once in contrast to results reported by the Pittsburgh Study or other studies reported by Hardesty and Fenske. The results do not comply with Trueswell's 20/80 ratio rule. Further research needs to investigate the effects of low students to books ratios and problem-based learning (PBL) curricula upon monographs utilization. PMID:9803291

Objective: To study the circulation of monographs during the first three years of shelf life at an academic health sciences library. Method: A record was kept of monographs added to the circulating collection from mid-1994 to mid-1995. After three years, each monograph was located and the number of times it circulated during the first, second, and third year of shelf life determined by counting checkout stamps on the circulation slip. Results: Of the 1,958 monographs studied, 1,674 had complete data for the first three years of shelf life. Of those 1,674 titles, 81.48% circulated at least once. A total of 7,659 circulations were recorded; 38.69% occurred in the first year of shelf life, 32.37% in the second year, and 28.95% in the third year. The data did not fit the well-known 80/20 rule. Instead, approximately 38% of monographs accounted for 80% of circulation. A small percentage, 2.21%, of monographs accounted for a substantial percentage of circulation, 21.84%. Conclusions: A large percentage of the monographs circulated and use did not decline sharply with age within the first three years of shelf life, indicating a high demand for monographs at this academic health sciences library. These results, combined with the findings of earlier studies, suggested two possibilities. First, academic health sciences libraries might exhibit use of a higher percentage of monograph acquisitions than other types of libraries; or, second, a low monograph-to-user ratio might result in a higher percentage of monographs being used. Perhaps both factors contributed to the results found in this study. Further investigation would be needed to determine the extent to which library type and monograph-to-user ratio influenced monograph use. PMID:10783969

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.
After reviewing and evaluating the existing material on sound propagation in curved ducts without flow, it seems strange that, except for Lord Rayleigh in 1878, no book on acoustics has treated the case of wave motion in bends. This monograph reviews the available analytical and experimental material, nearly 30 papers published on this subject so far, and concisely summarizes what has been learned about the motion of sound in hard-wall and acoustically lined cylindrical bends.

A description of the Center of Geophysical Monitoring for Systematic Investigation of Negative Consequences for the Human Environment and Infrastructure of the City of Moscow Resulting from Natural and Technogenic Factors, which is part of the Institute of Geosphere Dynamics of the Russian Academy of Sciences (IGD RAS), is presented. The results of synchronous observations of the seismic vibrations, electric and acoustic fields, and atmospheric meteoparameters performed at the Center and in the Mikhnevo Geophysical observatory of IGD RAS situated outside of the zone of the Moscow influence are examined. It is shown that the megalopolis influence consists of an increase in the amplitudes of the physical fields, a change in their spectral composition, and the violation of natural periodicities. A technogenic component that has a considerable impact on the natural physical processes in the surface atmosphere is an important factor that characterizes a megalopolis.

For more than a century, geophysicists who track Earth's rotation have sensed a rhythmic unsteadiness about the planet, an ever-so-slight wobbling whose source remained frustratingly mysterious. But researchers have been homing in on the roots of the so-called Chandler wobble, and now a report in the 1 August issue of Geophysical Research Letters fingers the shifting pressures of the deep sea and ultimately the fickle winds of the atmosphere.

Geophysical techniques play key roles in the measuring, monitoring, and verifying the safety of CO2 sequestration and in identifying the efficiency of CO2-enhanced oil recovery. Although geophysical monitoring techniques for CO2 sequestration have grown out of conventional oil and gas geophysical exploration techniques, it takes a long time to conduct geophysical monitoring, and there are many barriers and challenges. In this paper, with the initial objective of performing CO2 sequestration, we studied the geophysical tasks associated with evaluating geological storage sites and monitoring CO2 sequestration. Based on our review of the scope of geophysical monitoring techniques and our experience in domestic and international carbon capture and sequestration projects, we analyzed the inherent difficulties and our experiences in geophysical monitoring techniques, especially, with respect to 4D seismic acquisition, processing, and interpretation.

We are using Lawrence Livermore National Laboratory`s (LLNL`s) diverse expertise to develop a geophysical monitoring system that can survive being dropped into place by a helicopter or airplane. Such an air-deployable system could significantly decrease the time and effort needed to set up such instruments in remote locations following a major earthquake or volcanic eruption. Most currently available geophysical monitoring and survey systems, such as seismic monitoring stations, use sensitive, fragile instrumentation that requires personnel trained and experienced in data acquisition and field setup. Rapid deployment of such equipment can be difficult or impossible. Recent developments in low-power electronics, new materials, and sensors that are resistant to severe impacts have made it possible to develop low-cost geophysical monitoring packages for rapid deployment missions. Our strategy was to focus on low-cost battery-powered systems that would have a relatively long (several months) operational lifetime. We concentrated on the conceptual design and engineering of a single-component seismic system that could survive an air-deployment into an earth material, such as alluvium. Actual implementation of such a system is a goal of future work on this concept. For this project, we drew on LLNL`s Earth Sciences Department, Radio Shop, Plastics Shop, and Weapons Program. The military has had several programs to develop air-deployed and cannon-deployed seismometers. Recently, a sonobuoy manufacturer has offered an air-deployable geophone designed to make relatively soft landings.

SAGE, a field-based educational program in applied geophysical methods has been an REU site for 16 years and completed its 23rd year of operation in July 2005. SAGE teaches the major geophysical exploration methods (including seismics, gravity, magnetics, and electromagnetics) and applies them to the solution of specific local and regional geologic problems. These include delineating buried hazardous material; mapping archaeological sites; and studying the structure, tectonics, and water resources of the Rio Grande rift in New Mexico. Nearly 600 graduates, undergraduates, and professionals have attended SAGE since 1983. Since 1990 REU students have numbered 219 coming from dozens of different campuses. There have been 124 underrepresented REU students including 100 women, 14 Hispanics, 7 Native Americans, and 3 African Americans. Tracking of former REU students has revealed that 81% have gone on to graduate school. Keys to the success of SAGE are hands-on immersion in geophysics for one month and a partnership between academia, industry, and a federal laboratory. Successful approaches at SAGE include: 1) application of the latest equipment by all students; 2) continued updating of equipment, computers, and software by organizing universities and industry affiliates; 3) close ties with industry who provide supplemental instruction, furnish new equipment and software, and alert students to the current industry trends and job opportunities; 4) two-team, student data analysis structure that simultaneously addresses specific geophysical techniques and their integration; and 5) oral and written reports patterned after professional meetings and journals. An eight member, 'blue ribbon' advisory panel from academia, industry, and the federal government has been set up to maintain the vitality of SAGE by addressing such issues as funding, new faculty, organization, and vision. SAGE is open to students from any university (or organization) with backgrounds including

Geophysical models constitute an important component of calibration for nuclear explosion monitoring. We will focus on four major topics: (1) a priori geophysical models, (2) surface wave models, (3) receiver function derived profiles, and (4) stochastic geophysical models. The first, a priori models, can be used to predict a host of geophysical measurements, such as body wave travel times, and can be derived from direct regional studies or even by geophysical analogy. Use of these models is particularly important in aseismic regions or regions without seismic stations, where data of direct measurements might not exist. Lawrence Livermore National Laboratory (LLNL) has developed the Western Eurasia and North Africa (WENA) model which has been evaluated using a number of data sets, including travel times, surface waves, receiver functions, and waveform analysis (Pasyanos et al., 2004). We have joined this model with our Yellow Sea - Korean Peninsula (YSKP) model and the Los Alamos National Laboratory (LANL) East Asia model to construct a model for all of Eurasia and North Africa. Secondly, we continue to improve upon our surface wave model by adding more paths. This has allowed us to expand the region to all of Eurasia and into Africa, increase the resolution of our model, and extend results to even shorter periods (7 sec). High-resolution models exist for the Middle East and the YSKP region. The surface wave results can be inverted either alone, or in conjunction with other data, to derive models of the crust and upper mantle structure. We are also using receiver functions, in joint inversions with the surface waves, to produce profiles directly under seismic stations throughout the region. In a collaborative project with Ammon, et al., they have been focusing on stations throughout western Eurasia and North Africa, while we have been focusing on LLNL deployments in the Middle East, including Kuwait, Jordan, and the United Arab Emirates. Finally, we have been

Geophysical fluid dynamics deals with the motions and physics of the atmosphere, oceans and interior of the earth and other planets: the winds, the swirls, the currents that occur on myriads of scales from millimeter to climatological. Explanations of natural phenomena, basic processes and abstractions are sought. The rotation of the earth, the buoyancy of its fluids and the tendency towards large-scale turbulence characterize these flows. But geophysical fluid dynamics is importantly a part of modern fluid dynamics which is contributing to the development of nonlinear mechanics generally. Some general insights are emerging for nonlinear systems which must be regarded as partly deterministic and partly random or which are complex and aperiodic. Contributions from geophysical fluid dynamics come from its methodology, from the experience of examples, and from the perspective provided by its unique scale. Contributions have been made to turbulent, chaotic and coherently structured nonlinear process research. Turbulent vortices larger than man himself naturally invite detailed investigation and deterministic physical studies. Examples are storms in the atmosphere and large ring vortices spun off by the Gulf Stream current in mid-ocean. The statistics of these events determine critical aspects of the general circulations. Fluid dynamicists generally now know that it is often relevant or necessary to study local dynamical processes of typical eddies even though only the average properties of the flow are of interest; progress in understanding the turbulent boundary layer in pipes involves the study of millimeter-scale vortices. Weather-related studies were seminal to the construction of the new scientific field of chaos. Coherent vortices abound of which the Great Red Spot of Jupiter is a spectacular example. Geophysical fluid dynamicists have been among forefront researchers in exploiting the steadily increasing speed and capacity of modern computers. Supercomputers

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.

Most geophysical systems are macroscopic physical systems. The behavior prediction of such systems is carried out by means of computational models whose basic models are partial differential equations (PDEs) . Due to the enormous size of the discretized version of such PDEs it is necessary to apply highly parallelized super-computers. For them, at present, the most efficient software is based on non-overlapping domain decomposition methods (DDM). However, a limiting feature of the present state-of-the-art techniques is due to the kind of discretizations used in them. Recently, I. Herrera and co-workers using 'non-overlapping discretizations' have produced the DVS-Software which overcomes this limitation . The DVS-software can be applied to a great variety of geophysical problems and achieves very high parallel efficiencies (90%, or so ). It is therefore very suitable for effectively applying the most advanced parallel supercomputers available at present. In a parallel talk, in this AGU Fall Meeting, Graciela Herrera Z. will present how this software is being applied to advance MOD-FLOW.

Geophysical models constitute an important component of calibration for nuclear explosion monitoring. We will focus on four major topics and their applications: (1) surface wave models, (2) receiver function profiles, (3) regional tomography models, and (4) stochastic geophysical models. First, we continue to improve upon our surface wave model by adding more paths. This has allowed us to expand the region to all of Eurasia and into Africa, increase the resolution of our model, and extend results to even shorter periods (7 sec). High-resolution models exist for the Middle East and the YSKP region. The surface wave results can be inverted either alone, or in conjunction with other data, to derive models of the crust and upper mantle structure. One application of the group velocities is to construct phase-matched filters in combination with regional surface-wave magnitude formulas to improve the mb:Ms discriminant and extend it to smaller magnitude events. Next, we are using receiver functions, in joint inversions with the surface waves, to produce profiles directly under seismic stations throughout the region. In the past year, we have been focusing on deployments throughout the Middle East, including the Arabian Peninsula and Turkey. By assembling the results from many stations, we can see how regional seismic phases are affected by complicated upper mantle structure, including lithospheric thickness and anisotropy. The next geophysical model item, regional tomography models, can be used to predict regional travel times such as Pn and Sn. The times derived by the models can be used as a background model for empirical measurements or, where these don't exist, simply used as is. Finally, we have been exploring methodologies such as Markov Chain Monte Carlo (MCMC) to generate data-driven stochastic models. We have applied this technique to the YSKP region using surface wave dispersion data, body wave travel time data, receiver functions, and gravity data. The models
Active tectonics is defined within the study as tectonic movements that are expected to occur within a future time span of concern to society. Such movements and their associated hazards include earthquakes, volcanic eruptions, and land subsidence and emergence. The entire range of geology, geophysics, and geodesy is, to some extent, pertinent to this topic. The needs for useful forecasts of tectonic activity, so that actions may be taken to mitigate hazards, call for special attention to ongoing tectonic activity. Further progress in understanding active tectonics depends on continued research. Particularly important is improvement in the accuracy of dating techniques for recent geologic materials.
The adoption of the EU community monograph on Hypericum constitutes a milestone in the process of harmonisation of herbal medicinal products within the European Community. The assessment of the published clinical data revealed that for two types of extracts the evidence of the efficacy in mild to moderate depressive episodes compared to placebo or standard medication was found to be acceptable. Additionally, a sufficient efficacy in relapse prophylaxis could be demonstrated for these two herbal preparations. For some other dry extracts, the efficacy in the short-term treatment of symptoms in mild depressive disorders was found to be substantiated. Short-term treatment with preparations containing low amounts of hyperforin did not increase cytochrome P450 enzyme activity. Therefore the oral administration of traditional herbal preparations is restricted to two weeks. In the case that an applicant demonstrates that the daily intake of hyperforin is below 1 mg the warnings on interactions may be omitted in traditional herbal medicinal products. Additionally the cutaneous administration of traditional liquid herbal preparations for the traditional use in symptomatic treatment of minor inflammations of the skin and as an aid in healing minor wounds was included in the monograph.

The American Geophysical Union hosted a Chapman Conference on Communicating Climate Science at Snow Mountain Ranch, Granby, Colorado, June 8-13, 2013. The goal of the Chapman Conference was to bring together scholars, social scientists and journalists to discuss the history, and more importantly, the present and future of climate change communication. We met to evaluate our current and needed communication capacity, and to develop ways and means to convey advances in the understanding of climate science. Delegates discussed and presented methods and capacity to communicate to policymakers, the media, and society. Our focus was on the efficacy of scientific communication, on improving communication practices, and on building collaborations spawned at the conference, and beyond. The Chapman was a success. Close to 150 of us gathered high in the Colorado Rockies to share almost 100 presentations and nearly 10 hours of group discussions focused on ways and means to better bring the climate change message to society, to educators and policymakers in North America and around the world. This presentation will focus on the outcomes of the Chapman Climate Change Communication Conference; the conclusions of the delegate community; and directions forward.

The Environmental and Engineering Geophysical Society (EEGS), a nonprofit professional organization, conducted an educational series of seminars at the Symposium on the Application of Geophysics to Engineering and Environmental Problems (SAGEEP) in Philadelphia in April 2008. The purpose of these seminars, conducted under the name Environmental and Engineering Geophysical University (EEGU) over three days in parallel with the regular SAGEEP technical sessions, was to introduce nontraditional geophysical conference attendees to the appropriate use of geophysics in environmental and engineering projects. Five half-day, classroom-style sessions were led by recognized experts in the application of seismic, electrical, gravity, magnetics, and ground-penetrating radar methods. Classroom sessions were intended to educate regulators, environmental program managers, consultants, and students who are new to near-surface geophysics or are interested in learning how to incorporate appropriate geophysical approaches into characterization or remediation programs or evaluate the suitability of geophysical methods for general classes of environmental or engineering problems.

This report documents the evolution of the surface geophysical exploration (SGE) program and highlights some of the most recent successes in imaging conductive targets related to past leaks within and around Hanford's tank farms. While it is noted that the SGE program consists of multiple geophysical techniques designed to (1) locate near surface infrastructure that may interfere with (2) subsurface plume mapping, the report will focus primarily on electrical resistivity acquisition and processing for plume mapping. Due to the interferences from the near surface piping network, tanks, fences, wells, etc., the results of the three-dimensional (3D) reconstruction of electrical resistivity was more representative of metal than the high ionic strength plumes. Since the first deployment, the focus of the SGE program has been to acquire and model the best electrical resistivity data that minimizes the influence of buried metal objects. Toward that goal, two significant advances have occurred: (1) using the infrastructure directly in the acquisition campaign and (2) placement of electrodes beneath the infrastructure. The direct use of infrastructure was successfully demonstrated at T farm by using wells as long electrodes (Rucker et al., 2010, 'Electrical-Resistivity Characterization of an Industrial Site Using Long Electrodes'). While the method was capable of finding targets related to past releases, a loss of vertical resolution was the trade-off. The burying of electrodes below the infrastructure helped to increase the vertical resolution, as long as a sufficient number of electrodes are available for the acquisition campaign.
Although reductions in lead (Pb) exposure for the U.S. population have resulted in lower blood Pb levels over time, epidemiological studies continue to provide evidence of health effects at lower and lower blood Pb levels. Low-level Pb was selected for evaluation by the National Toxicology Program (NTP) because of (1) the availability of a large number of epidemiological studies of Pb, (2) a nomination by the National Institute for Occupational Safety and Health for an assessment of Pb at lower levels of exposure, and (3) public concern for effects of Pb in children and adults. This evaluation summarizes the evidence in humans and presents conclusions on health effects in children and adults associated with low-level Pb exposure as indicated by less than 10 micrograms of Pb per deciliter of blood (< 10 microg/dL). The assessment focuses on epidemiological evidence at blood Pb levels < 10 microg/dL and < 5 microg/dL because health effects at higher blood Pb levels are well established. The NTP evaluation was conducted through the Office of Health Assessment and Translation (OHAT, formerly the Center for the Evaluation of Risks to Human Reproduction) and completed in April of 2012. The results of this evaluation are published in the NTP Monograph on Health Effects of Low-Level Lead. The document and appendices are available at http://ntp.niehs.nih.gov/go/evals. This document provides background on Pb exposure and includes a review of the primary epidemiological literature for evidence that low-level Pb is associated with neurological, immunological, cardiovascular, renal, and/or reproductive and developmental effects. The NTP Monograph presents specific conclusions for each health effect area. Overall, the NTP concludes that there is sufficient evidence that blood Pb levels < 10 microg/dL and < 5 microg/dL are associated with adverse health effects in children and adults. This conclusion was based on a review of the primary epidemiological literature, scientific

The United Nations' Educational, Scientific and Cultural Organization (UNESCO) declared 2005 the “World Year of Physics” in celebration of the centennial of Einstein's annus mirabilis when, as junior clerk at the Swiss Patent Office in Berne, he published three papers that changed physics forever by (1) introducing Special Relativity and demonstrating the equivalence of mass and energy (E = mc2), (2) explaining the photoelectric effect with Planck's then-still-new-and-controversial concept of light quanta (E = hv), and (3) investigating the macroscopic phenomenon of Brownian motion using Boltzmann's molecular dynamics (E = kT), still far from fully accepted at the time.The celebration of Einstein's work in physics inspires the reflection on the status of geophysics and its relationship with physics, in particular with respect to great discoveries.

Several types of sensitive strainmeters and tiltmeters have been developed, and it is now becoming clear which geophysical applications are most suitable for these instruments. In general, strainmeters and tiltmeters are used for observing ground deformation at periods of minutes to days. Small-scale lateral inhomogeneities at the instrument sites distort signals by a few percent, although the effects of large structures can be calculated. In earth tide work these lateral inhomogeneities and unknown ocean loading signals prevent accurate values of the regional tide from being obtained. This limits tidal investigations to looking for temporal variations, possibly associated with pre-earthquake dilatancy, and spatial variations caused by gross elasticity contrasts in the local geological structure. Strainmeters and tiltmeters are well suited for observing long-period seismic waves, seismic slip events on faults and volcano tumescence, where small site-induced distortions in the measured signals are seldom important.

The definition of a fractal distribution is that the number of objects N with a characteristic size greater than r scales with the relation N of about r exp -D. The frequency-size distributions for islands, earthquakes, fragments, ore deposits, and oil fields often satisfy this relation. This application illustrates a fundamental aspect of fractal distributions, scale invariance. The requirement of an object to define a scale in photograhs of many geological features is one indication of the wide applicability of scale invariance to geological problems; scale invariance can lead to fractal clustering. Geophysical spectra can also be related to fractals; these are self-affine fractals rather than self-similar fractals. Examples include the earth's topography and geoid.

Data Collection Platforms (DCPs) for transmitting surface data to an orbiting satellite for relaying to a central data distribution center are being used in a number of geophysical applications. "Off-the-shelf" DCP's, transmitting through Landsat or GOES satellites, are fully capable of relaying data from low-data-rate instruments, such as tiltmeters or tide gauges. In cooperation with the Lamont-Doherty Geological Observatory, Goddard has successfully installed DCP systems on a tide gauge and tiltmeter array on Anegada, British Virgin Islands. Because of the high-data-rate requirements, a practical relay system capable of handling seismic information is not yet available. Such a system could become the basis of an operational hazard prediction system for reducing losses due to major natural catastrophies such as earthquakes, volcanic eruptions, landslides or tsunamis.

An experiment run in 2009 could not assess whether making monographs available in open access enhanced scholarly impact. This paper revisits the experiment, drawing on additional citation data and tweets. It attempts to answer the following research question: does open access have a positive influence on the number of citations and tweets a monograph receives, taking into account the influence of scholarly field and language? The correlation between monograph citations and tweets is also investigated. The number of citations and tweets measured in 2014 reveal a slight open access advantage, but the influence of language or subject should also be taken into account. However, Twitter usage and citation behaviour hardly overlap.

With deforestation in the Asia-Pacific region progressing at the rate of 4.4 million ha per year, many countries have adopted plantation forestry using fast-growing species as a way to sustain the commercial supply of tree products and reduce pressure on natural forests. Acacia mangium (A. mangium) is playing a large role in this development, especially in Indonesia and Malaysia, due to its versatility and its ability to recapture grasslands dominated by the noxious weed, Imperata cylindrica. This monograph consolidates information on A. mangium from published literature, unpublished reports and studies, and observations from those familiar with the species. Priorities for future research are included in each chapter and in the final summary.
Background Each day, millions of health consumers seek drug-related information on the Web. Despite some efforts in linking related resources, drug information is largely scattered in a wide variety of websites of different quality and credibility. Methods As a step toward providing users with integrated access to multiple trustworthy drug resources, we aim to develop a method capable of identifying drug's dosage form information in addition to drug name recognition. We developed rules and patterns for identifying dosage forms from different sections of full-text drug monographs, and subsequently normalized them to standardized RxNorm dosage forms. Results Our method represents a significant improvement compared with a baseline lookup approach, achieving overall macro-averaged Precision of 80%, Recall of 98%, and F-Measure of 85%. Conclusions We successfully developed an automatic approach for drug dosage form identification, which is critical for building links between different drug-related resources. PMID:22336431

Literature on sleep and child development is growing rapidly in exciting new directions across several disciplines and with this comes a need for guiding conceptual principles and methodological tools. In this introductory chapter, the importance of sleep for child development across multiple domains is highlighted. The aims of this monograph are presented and pertain to the need to consider and integrate theory and research across multiple disciplines and use state-of-the-art methodologies. A developmental ecological systems perspective adapted to sleep illustrates the multiple levels of influence and their importance in the study of child sleep and development. A focal aim is to provide examples of longitudinal studies linking sleep with child development, which are presented in seven chapters of this volume.

The onset of silicate magma generation in the Earth's upper mantle influences the thermal evolution of the planet, fluxes of key volatiles to the exosphere, and geochemical and geophysical properties of the mantle. Although carbonatitic fluid with variable water content could be stable ≤250 km beneath mid oceanic ridges [1-3], owing to the small fraction (<< 1 wt.%), its effects on the mantle properties are unclear. Geophysical measurements, however, suggest that melts of greater volume may be present down to ~200 km [4-6] but large melt fractions is thought to be restricted to shallower depths. In this Kuno Award lecture, I will discuss the recent advancements on our understanding of deeper silicate melt generation induced by CO2-H2O volatiles and the relative stability of silicate versus carbonatitic melt in various tectonic settings. I will present recent experiments on carbonated peridotites that constrain the location and the slope of the onset of silicate melting in the mantle . The new finding is that the pressure-temperature slope of carbonated silicate melting is steeper than the solidus of volatile-free peridotite and as a consequence the silicate melting of dry peridotite+CO2 beneath ridges commences at ~180 km. Accounting for the effect of 50-200 ppm of mantle H2O on freezing point depression, the onset of silicate melting for a sub-ridge mantle with ~100 ppm CO2 becomes as deep as ~220-300 km . This melting generates a kimberlitic magma with ~25 wt.% dissolved CO2 and 1-5 wt.% dissolved H2O. Based on the recent constraints of oxygen fugacity of the mantle in the garnet peridotite field [2, 3], we suggest that on a global scale, carbonated silicate melt generation at ~250-180 km deep redox solidus, with destabilization of metal and majorite in the upwelling mantle, explains oceanic low-velocity zone and electrical conductivity structure of the mantle. In locally oxidized domains (i.e., higher than average Fe3+/Fetotal), deeper carbonated
Journal of Geophysics and Engineering (JGE) aims to publicize and promote research and developments in geophysics and in related areas of engineering. As stated in the journal scope, JGE is positioned to bridge the gap between earth physics and geo-engineering, where it reflects a growing trend in both industry and academia. JGE covers those aspects of engineering that bear closely on geophysics or on the targets and problems that geophysics addresses. Typically this will be engineering focused on the subsurface, particularly petroleum engineering, rock mechanics, geophysical software engineering, drilling technology, remote sensing, instrumentation and sensor design. There is a trend, visible throughout academia, for rapid expansion in cross-disciplinary, multi-disciplinary and inter-disciplinary working. Many of the most important and exciting problems and advances are being made at the boundaries between traditional subject areas and, increasingly, techniques from one discipline are finding applications in others. There is a corresponding increasing requirement for researchers to be aware of developments in adjacent areas and for papers published in one area to be readily accessible, both in terms of location and language, to those in others. One such area that is expanding rapidly is that at the interface between geophysics and engineering. There are three principal developments. Geophysics, and especially applied geophysics, is increasingly constrained by the limits of technology, particularly computing technology. Consequently, major advances in geophysics are often predicated upon major developments in engineering and many research geophysicists are working in multi-disciplinary teams with engineers. Engineering problems relevant to the sub-surface are increasingly looking to advances in geophysics to provide part of the solution. Engineering systems, for example, for tunnel boring or petroleum reservoir management, are using high-resolution geophysical

Earth's atmosphere and oceans exhibit complex patterns of fluid motion over a vast range of space and time scales. These patterns combine to establish the climate in response to solar radiation that is inhomogeneously absorbed by the materials comprising air, water, and land. Spontaneous, energetic variability arises from instabilities in the planetary-scale circulations, appearing in many different forms such as waves, jets, vortices, boundary layers, and turbulence. Geophysical fluid dynamics (GFD) is the science of all these types of fluid motion. This textbook is a concise and accessible introduction to GFD for intermediate to advanced students of the physics, chemistry, and/or biology of Earth's fluid environment. The book was developed from the author's many years of teaching a first-year graduate course at the University of California, Los Angeles. Readers are expected to be familiar with physics and mathematics at the level of general dynamics (mechanics) and partial differential equations. Covers the essential GFD required for atmospheric science and oceanography courses Mathematically rigorous, concise coverage of basic theory and applications to both oceans and atmospheres Author is a world expert; this book is based on the course he has taught for many years Exercises are included, with solutions available to instructors from firstname.lastname@example.org

Amid the current confusion surrounding the pending fate of the United States Department of Energy (President Reagan proposed a plan to ‘dismantle’ it), a rather large program, sometimes called ‘Physical Research in the Geosciences,’ survives in financially healthy condition. According to the recent report ‘Summary Outline of DOE Geoscience and Geoscience-Related Research (DOE/ER-0120, Feb. 1982), the amount of funding granted to university researchers for the current fiscal year is $16 million.In a procedure similar to other federal government unsolicited grant research proplate grams, funds are awarded to successful university applicants on the basis of research proposals. An interesting note is that apparently because of the uncertainties surrounding the futures of several federal programs, including the DOE, some researchers have assumed, incorrectly, that many sources of research funding may be discontinued. Meanwhile, program directors of the National Science Foundation have told Eos that their programs are experiencing a large increase in research proposals because investigators are apparently seeking other sources of funding. As the Office of Management Budget request for fiscal year 1983 stands at the present time, funding for geophysical energy research will be increased substantially under the Office of Basic Energy Sciences.

OBJECTIVES Children require special considerations for drug prescribing. Drug information summarized in a formulary containing drug monographs is essential for safe and effective prescribing. Currently, little is known about the information needs of those who prescribe and administer medicines to children. Our primary objective was to identify a list of important and relevant items to be included in a pediatric drug monograph. METHODS Following the establishment of an expert steering committee and an environmental scan of adult and pediatric formulary monograph items, 46 participants from 25 countries were invited to complete a 2-round Delphi survey. Questions regarding source of prescribing information and importance of items were recorded. An international consensus meeting to vote on and finalize the items list with the steering committee followed. RESULTS Pediatric formularies are most commonly the first resource consulted for information on medication used in children by 31 Delphi participants. After the Delphi rounds, 116 items were identified to be included in a comprehensive pediatric drug monograph, including general information, adverse drug reactions, dosages, precautions, drug-drug interactions, formulation, and drug properties. CONCLUSIONS Health care providers identified 116 monograph items as important for prescribing medicines for children by an international consensus-based process. This information will assist in setting standards for the creation of new pediatric drug monographs for international application and for those involved in pediatric formulary development.

Product monographs (also known by terms such as Summary of Product Characteristics and Highlights of Prescribing Information, depending on the jurisdiction) provide essential information to ensure the safe and effective use of a drug. Medical practitioners often rely on these monographs for guidance on matters related to pharmacokinetics as well as indications, contraindications, clinical pharmacology, and adverse reactions. The clinical and scientific information found within these documents, forming the basis for decision making, are presumed to be derived from well-designed studies. The objective of this review is to examine the source and validity of the pharmacokinetic data used in establishing the half-lives and times to steady-state reported in the product monographs of second-generation long-acting injectable antipsychotics. Thus, we have critically evaluated the clinical trials from which the pharmacokinetic parameters listed in the product monographs were determined. In many cases, the pharmacokinetic information presented in product monographs is of limited use to clinicians wishing to optimize the effectiveness and tolerability of second-generation long-acting injectable antipsychotics. Under such circumstances, off-label prescribing practices may actually produce better clinical outcomes than if decisions were made based on the product monographs alone.

In the paper the new theoretical and methodical approaches are examined for detailed investigations of the structure and state of the geological medium, and its behavior as a dynamic system in reaction to external man-made influences. To solve this problem it is necessary to use geophysical methods that have sufficient resolution and that are built on more complicated models than layered or layered-block models. One of these methods is the electromagnetic induction frequency-geometrical method with controlled sources. Here we consider new approaches using this method for monitoring rock shock media by means of natural experiments and interpretation of the practical results. That method can be used by oil production in mines, where the same events of non stability can occur. The key ideas of twenty first century geophysics from the point of view of geologist academician A.N. Dmitrievskiy [Dmitrievskiy, 2009] are as follows. "The geophysics of the twenty first century is an understanding that the Earth is a self-developing, self-supporting geo-cybernetic system, in which the role of the driving mechanism is played by the field gradients; the evolution of geological processes is a continuous chain of transformations and the interaction of geophysical fields in the litho- hydro- and atmosphere. The use of geophysical principles of a hierarchical quantum of geophysical space, non-linear effects, and the effects of reradiating geophysical fields will allow the creation of a new geophysics. The research, in which earlier only pure geophysical processes and technologies were considered, nowadays tends to include into consideration geophysical-chemical processes and technologies. This transformation will allow us to solve the problems of forecasting geo-objects and geo-processes in previously unavailable geological-technological conditions." The results obtained allow us to make the following conclusions, according to the key ideas of academician A.N. Dmitrievskiy: the rock
Soy infant formula contains soy protein isolates and is fed to infants as a supplement to or replacement for human milk or cow milk. Soy protein isolates contains estrogenic isoflavones ("phytoestrogens") that occur naturally in some legumes, especially soybeans. Phytoestrogens are non-steroidal, estrogenic compounds. In plants, nearly all phytoestrogens are bound to sugar molecules and these phytoestrogen-sugar complexes are not generally considered hormonally active. Phytoestrogens are found in many food products in addition to soy infant formula, especially soy-based foods such as tofu, soy milk, and in some over-the-counter dietary supplements. Soy infant formula was selected for evaluation by the National Toxicology Program (NTP) because of the: (1)availability of large number of developmental toxicity studies in laboratory animals exposed to the isoflavones found in soy infant formula (namely, genistein) or other soy products, as well as a number of studies on human infants fed soy infant formula, (2)the availability of information on exposures in infants fed soy infant formula, and (3)public concern for effects on infant or child development. The NTP evaluation was conducted through its Center for the Evaluation of Risks to Human Reproduction (CERHR) and completed in September 2010. The results of this soy infant formula evaluation are published in an NTP Monograph. This document contains the NTP Brief on Soy Infant Formula, which presents NTP's opinion on the potential for exposure to soy infant formula to cause adverse developmental effects in humans. The NTP Monograph also contains an expert panel report prepared to assist the NTP in reaching conclusions on soy infant formula. The NTP concluded there is minimal concern for adverse effects on development in infants who consume soy infant formula. This level of concern represents a "2" on the five-level scale of concern used by the NTP that ranges from negligible concern ("1") to serious concern ("5"). This

Specific reference figures are recommended for consistent use in geophysics and geodesy. The selection of appropriate reference figure for geophysical studies suggests a relationship between the Antarctic negative gravity anomaly and the great shrinkage of the Antarctic ice cap about 4-5 million years ago. The depression of the south polar regions relative to the north polar regions makes the Southern Hemisphere flatter than the Northern Hemisphere, thus producing the third harmonic (pear-shaped) contribution to the earth's figure.

Details of Earth's shallow subsurface—a key component of the critical zone (CZ)—are largely obscured because making direct observations with sufficient density to capture natural characteristic spatial variability in physical properties is difficult. Yet this inaccessible region of the CZ is fundamental to processes that support ecosystems, society, and the environment. Geophysical methods provide a means for remotely examining CZ form and function over length scales that span centimeters to kilometers. Here we present a review highlighting the application of geophysical methods to CZ science research questions. In particular, we consider the application of geophysical methods to map the geometry of structural features such as regolith thickness, lithological boundaries, permafrost extent, snow thickness, or shallow root zones. Combined with knowledge of structure, we discuss how geophysical observations are used to understand CZ processes. Fluxes between snow, surface water, and groundwater affect weathering, groundwater resources, and chemical and nutrient exports to rivers. The exchange of gas between soil and the atmosphere have been studied using geophysical methods in wetland areas. Indirect geophysical methods are a natural and necessary complement to direct observations obtained by drilling or field mapping. Direct measurements should be used to calibrate geophysical estimates, which can then be used to extrapolate interpretations over larger areas or to monitor changing processes over time. Advances in geophysical instrumentation and computational approaches for integrating different types of data have great potential to fill gaps in our understanding of the shallow subsurface portion of the CZ and should be integrated where possible in future CZ research.

The application of remote sensors for obtaining geophysical information of the Arctic regions is discussed. Two significant requirements are to acquire sequential, synoptic imagery of the Arctic Ocean during all weather and seasons and to measure the strains in the sea ice canopy and the heterogeneous character of the air and water stresses acting on the canopy. The acquisition of geophysical data by side looking radar and microwave sensors in military aircraft is described.

Levees are important engineering structures that build along the rivers to protect the human lives and shield the communities as well as agriculture lands from the high water level events. Animal burrows, subsurface cavities, and low density (high permeability) zones are weakness features within the levee body that increase its risk of failure. To prevent such failure, continuous monitoring of the structure integrity and early detection of the weakness features must be conducted. Application of Ground Penetrating Radar (GPR) and Capacitively Coupled Resistivity (CCR) methods were found to be very effective in assessing the levees and detect zones of weakness within the levee body. GPR was implemented using multi-frequency antennas (200, 400, and 900 MHz) with survey cart/wheel and survey vehicle. The (CCR) method was applied by using a single transmitter and three receivers. Studying the capability and the effectiveness of these methods in levee monitoring, subsurface weakness feature detection, and studying the structure integrity of levees were the main tasks of this dissertation. A set of laboratory experiments was conducted at the Geophysics Laboratory of the University of Arkansas at Little Rock (UALR) to analyze the polarity change in GPR signals in the presence of subsurface voids and water-filled cavities. Also three full scale field expeditions at the Big Dam Bridge (BDB) Levee, Lollie Levee, and Helena Levee in Arkansas were conducted using the GPR technique. This technique was effective in detecting empty, water, and clay filled cavities as well as small scale animal burrows (small rodents). The geophysical work at BDB and Lollie Levees expressed intensive subsurface anomalies which might decrease their integrity while the Helena Levee shows less subsurface anomalies. The compaction of levee material is a key factor affecting piping phenomenon. The structural integrity of the levee partially depends on the density/compaction of the soil layers. A

This chapter considers the application of a number of different geophysical techniques for monitoring geologic sequestration of CO2. The relative merits of the seismic, gravity, electromagnetic (EM) and streaming potential (SP) geophysical techniques as monitoring tools are examined. An example of tilt measurements illustrates another potential monitoring technique, although it has not been studied to the extent of other techniques in this chapter. This work does not represent an exhaustive study, but rather demonstrates the capabilities of a number of geophysical techniques on two synthetic modeling scenarios. The first scenario represents combined CO2 enhance oil recovery (EOR) and sequestration in a producing oil field, the Schrader Bluff field on the north slope of Alaska, USA. The second scenario is of a pilot DOE CO2 sequestration experiment scheduled for summer 2004 in the Frio Brine Formation in South Texas, USA. Numerical flow simulations of the CO2 injection process for each case were converted to geophysical models using petrophysical models developed from well log data. These coupled flow simulation geophysical models allow comparrison of the performance of monitoring techniques over time on realistic 3D models by generating simulated responses at different times during the CO2 injection process. These time-lapse measurements are used to produce time-lapse changes in geophysical measurements that can be related to the movement of CO2 within the injection interval.

In Lorraine region (France) salt layers at about 200 meters depth are exploited by Solvay using solution mining methodology which consists in extracting the salt by dissolution, collapsing the cavern overburden during the exploitation phase and finally reclaiming the landscape by creating a water area. In this process, one of the main challenges for the exploiting company is to control the initial 120-m diameter collapse so as to minimize possible damages. In order to detect potential precursors and understand processes associated with such collapses, a wide series of monitoring techniques including micro seismics, broad-band seismology, hydro-acoustic, electromagnetism, gas probing, automatic leveling, continuous GPS, continuous gravity and borehole extensometry was set-up in the frame of an in-situ study carried out by the "Research Group for the Impact and Safety of Underground Works" (GISOS, France). Equipments were set-up well before the final collapse, giving a unique opportunity to analyze a great deal of information prior to and during the collapse process which has been successfully achieved on February the 13th, 2009 by controlling the cavity internal pressure. In this work, we present the results of data recorded by a network of 3 broadband seismometers, 2 accelerometers, 2 tilt-meters and a continuously gravity meter. We relate the variations of the brine pumping rate with the evolutions of the induced geophysical signals and finally we propose a first mechanical model for describing the controlled collapse. Beyond the studied case, extrapolation of the results obtained might contribute to the understanding of uncontrolled cavity collapses, such as pit-craters or calderas at volcanoes.

The prediction of the mobility of geophysical flows to assess their hazards is one of the main research goals in the earth sciences. Our laboratory experiments and numerical simulations are carried out to understand the effects of grain size and flow volume on the mobility of the centre of mass of dry granular flows of angular rock fragments that have pyroclastic flows and rock avalanches as counterpart in nature. We focus on the centre of mass because it provides information about the intrinsic ability of a flow to dissipate more or less energy as a function of its own features. We show that the grain size and flow volume effects can be expressed by a linear relationship between scaling parameters where the finer the grain size or the smaller the flow volume, the more mobile the centre of mass of the granular flow. The grain size effect is the result of the decrease of particle agitation per unit of flow mass, and thus, the decrease of energy dissipation per unit of travel distance, as grain size decreases. In this sense, flows with different grain sizes are like cars with engines with different fuel efficiencies. The volume effect is the result of the fact that the deposit accretes backward during its formation on a slope change (either gradual or abrupt). We adopt for the numerical simulations a 3D discrete element modeling which confirms the grain size and flow volume effects shown by the laboratory experiments. This confirmation is obtained without prior fine tuning of the parameter values to get the desired output. The numerical simulations reveal also that the larger the initial compaction of the granular mass before release, the more mobile the flow. This behaviour must be taken into account to prevent misinterpretation of laboratory and field data. Discrete element modeling predicts the correct effects of grain size and flow volume because it takes into consideration particle interactions that are responsible for the energy dissipated by the flows.

As a SETI Institute PI from 1996-1998, Erik Asphaug studied impact and tidal physics and other geophysical processes associated with small (low-gravity) planetary bodies. This work included: a numerical impact simulation linking basaltic achondrite meteorites to asteroid 4 Vesta (Asphaug 1997), which laid the groundwork for an ongoing study of Martian meteorite ejection; cratering and catastrophic evolution of small bodies (with implications for their internal structure; Asphaug et al. 1996); genesis of grooved and degraded terrains in response to impact; maturation of regolith (Asphaug et al. 1997a); and the variation of crater outcome with impact angle, speed, and target structure. Research of impacts into porous, layered and prefractured targets (Asphaug et al. 1997b, 1998a) showed how shape, rheology and structure dramatically affects sizes and velocities of ejecta, and the survivability and impact-modification of comets and asteroids (Asphaug et al. 1998a). As an affiliate of the Galileo SSI Team, the PI studied problems related to cratering, tectonics, and regolith evolution, including an estimate of the impactor flux around Jupiter and the effect of impact on local and regional tectonics (Asphaug et al. 1998b). Other research included tidal breakup modeling (Asphaug and Benz 1996; Schenk et al. 1996), which is leading to a general understanding of the role of tides in planetesimal evolution. As a Guest Computational Investigator for NASA's BPCC/ESS supercomputer testbed, helped graft SPH3D onto an existing tree code tuned for the massively parallel Cray T3E (Olson and Asphaug, in preparation), obtaining a factor xIO00 speedup in code execution time (on 512 cpus). Runs which once took months are now completed in hours.

The technical establishment of boar sperm cryopreservation is indispensable for effective breeding of the scarce Okinawan native Agu pig. The objective was to determine whether an artificial anticell death protein (PTD-FNK protein) was capable of improving the quality of cryopreserved Agu sperm. Ejaculated Agu sperm frozen in an extender supplemented with 0, 100, 200, 300, or 400 nm PTD-FNK protein was thawed, and mitochondrial integrity and other sperm characteristics were evaluated. Treatment with 300 nm PTD-FNK protein had the most beneficial effect (P < 0.05) on mitochondrial integrity (45-59%) and sperm motility (56-67%) after freezing-thawing. In particular, the proportion of post-thaw sperm with activated caspase-9 and -3 but not caspase-8 was markedly reduced among sperm frozen in the presence of PTD-FNK protein (P < 0.05), implying protection against apoptotic-cell death in response to mitochondrial damage. There were high levels of intracellular ATP (9.4-10.5 nmol/10(8) sperm) in post-thaw sperm treated with PTD-FNK protein, and the inhibitory effect of PTD-FNK protein on activation of caspases influenced the increase in the number of sperm with intact DNA (36-53%; P < 0.05). Furthermore, the addition of PTD-FNK protein to the freezing extender strongly preserved the ability of the sperm to penetrate to mature oocytes in all individuals (60-80%; P < 0.05). In conclusion, treatment with PTD-FNK protein in the freezing extender effectively improved post-thaw qualities of fragile Agu sperm through prevention of mitochondrial dysfunction leading to apoptotic-cell death during cryopreservation.

An extracellular alpha-glucuronidase was purified and characterized from a commercial Aspergillus preparation and from culture filtrate of Aspergillus tubingensis. The enzyme has a molecular mass of 107 kDa as determined by sodium dodecyl sulfate-polyacrylamide gel electrophoresis and 112 kDa as determined by mass spectrometry, has a determined pI just below 5.2, and is stable at pH 6.0 for prolonged times. The pH optimum for the enzyme is between 4.5 and 6.0, and the temperature optimum is 70 degrees C. The alpha-glucuronidase is active mainly on small substituted xylo-oligomers but is also able to release a small amount of 4-O-methylglucuronic acid from birchwood xylan. The enzyme acts synergistically with endoxylanases and beta-xylosidase in the hydrolysis of xylan. The enzyme is N glycosylated and contains 14 putative N-glycosylation sites. The gene encoding this alpha-glucuronidase (aguA) was cloned from A. tubingensis. It consists of an open reading frame of 2,523 bp and contains no introns. The gene codes for a protein of 841 amino acids, containing a eukaryotic signal sequence of 20 amino acids. The mature protein has a predicted molecular mass of 91,790 Da and a calculated pI of 5.13. Multiple copies of the gene were introduced in A. tubingensis, and expression was studied in a highly overproducing transformant. The aguA gene was expressed on xylose, xylobiose, and xylan, similarly to genes encoding endoxylanases, suggesting a coordinate regulation of expression of xylanases and alpha-glucuronidase. Glucuronic acid did not induce the expression of aguA and also did not modulate the expression on xylose. Addition of glucose prevented expression of aguA on xylan but only reduced the expression on xylose.

Oldoinyo Lengai, which means "Mountain of God" in Maasai, is a 2886 m high stratovolcano situated in Northern Tanzania, next to one of the large fault scarps that defines the western edge of the East African Rift Valley. Lengai is the only volcano in the world that erupts natrocarbonatite lava and has been in a state of near-eruption since 1983. A large amount of work has been done in terms of the geology and petrology of this unique volcano, but very little has been done in terms of geophysics. A research team from the University of the Witwatersrand, South Africa will be conducting a gravity and differential GPS survey on Lengai during December 2006 and January 2007. Seismic monitoring of the volcano will also take place for the duration of the survey using vertical 1 Hz geophones. A gravity profile collected over the volcano by the British Schools Exploring Society in 2004 shows a negative anomaly of approximately 185 mGals. This is after a terrain correction is applied to the data using 1:50000 digitized maps and a vertical prism formula. A single seismometer, with a frequency of 1Hz and then 0.033 Hz, was set up on the volcano in 2001 and 2002 by a graduate student from the University of Washington. A few local volcanotectonic (VT) events were recorded; however the research team was unable to conclude whether the events were from Lengai or the nearby rift. A sustained non-harmonic tremor signal with a fairly broad spectral peak was also observed, but no very long-period (VLP) signals. The gravity and DGPS data collected during the 2006/2007 survey will be processed and used as a baseline for future measurements on the volcano. The data will also be modeled in an attempt to determine the size and position of the magma chamber. These gravity data will be compared with the profile collected in 2004 in an attempt to see whether there have been any large subsurface mass changes over the past two years, or the extent of weathering. Recorded seismicity will be used

Background: Recently, the International Agency for Research on Cancer (IARC) Programme for the Evaluation of Carcinogenic Risks to Humans has been criticized for several of its evaluations, and also for the approach used to perform these evaluations. Some critics have claimed that failures of IARC Working Groups to recognize study weaknesses and biases of Working Group members have led to inappropriate classification of a number of agents as carcinogenic to humans. Objectives: The authors of this Commentary are scientists from various disciplines relevant to the identification and hazard evaluation of human carcinogens. We examined criticisms of the IARC classification process to determine the validity of these concerns. Here, we present the results of that examination, review the history of IARC evaluations, and describe how the IARC evaluations are performed. Discussion: We concluded that these recent criticisms are unconvincing. The procedures employed by IARC to assemble Working Groups of scientists from the various disciplines and the techniques followed to review the literature and perform hazard assessment of various agents provide a balanced evaluation and an appropriate indication of the weight of the evidence. Some disagreement by individual scientists to some evaluations is not evidence of process failure. The review process has been modified over time and will undoubtedly be altered in the future to improve the process. Any process can in theory be improved, and we would support continued review and improvement of the IARC processes. This does not mean, however, that the current procedures are flawed. Conclusions: The IARC Monographs have made, and continue to make, major contributions to the scientific underpinning for societal actions to improve the public’s health.

An evaluation of high-resolution geophysical techniques which can be used to characterize a nulcear waste disposal site is being conducted by the Lawrence Livermore National Laboratory (LLNL) at the request of the US Nuclear Regulatory Commisson (NRC). LLNL is involved in research work aimed at evaluating the current capabilities and limitations of geophysical methods used for site selection. This report provides a brief overview of the capabilities and limitations associated with this technology and explains how our work addresses some of the present limitations. We are examining both seismic and electromagnetic techniques to obtain high-resolution information. We are also assessing the usefulness of geotomography in mapping fracture zones remotely. Finally, we are collecting core samples from a site in an effort to assess the capability of correlating such geophysical data with parameters of interest such as fracture continuity, orientation, and fracture density.

Geophysical models are increasingly recognized as an important component of regional calibrations for seismic monitoring. The models can be used to predict geophysical measurements, such as body wave travel times, and can be derived from direct regional studies or even by geophysical analogy. While empirical measurements of these geophysical parameters might be preferred, in aseismic regions or regions without seismic stations, this data might not exist. In these cases, models represent a 'best guess' of the seismic properties in a region, which improves on global models such as the PREM (Preliminary Reference Earth Model) or the IASPEI (International Association of Seismology and Physics of the Earth's Interior) models. The model-based predictions can also serve as a useful background for the empirical measurements by removing trends in the data. To this end, Lawrence Livermore National Laboratory (LLNL) has developed the WENA model for Western Eurasia and North Africa. This model is constructed using a regionalization of several dozen lithospheric (crust and uppermost mantle) models, combined with the Laske sediment model and 3SMAC upper mantle. We have evaluated this model using a number of data sets, including travel times, surface waves, receiver functions, and waveform analysis. Similarly, Los Alamos National Laboratory (LANL) has developed a geophysical model for East Asia, allowing LLNL/LANL to construct a model for all of Eurasia and North Africa. These models continue to evolve as new and updated datasets are used to critically assess the predictive powers of the model. Research results from this meeting and other reports and papers can be used to update and refine the regional boundaries and regional models. A number of other groups involved in monitoring have also developed geophysical models.

Integration of geophysical data obtained at various scales can bridge the gap between localized data from boreholes and site-wide data from regional survey profiles. Specific approaches to such analysis include: 1) comparing geophysical measurements in boreholes with the same measurement made from the surface; 2) regressing geophysical data obtained in boreholes with water-sample data from screened intervals; 3) using multiple, physically independent measurements in boreholes to develop multivariate response models for surface geophysical surveys; 4) defining subsurface cell geometry for most effective survey inversion methods; and 5) making geophysical measurements in boreholes to serve as independent verification of geophysical interpretations. Integrated analysis of surface electromagnetic surveys and borehole geophysical logs at a study site in south Florida indicates that salinity of water in the surficial aquifers is controlled by a simple wedge of seawater intrusion along the coast and by a complex pattern of upward brine seepage from deeper aquifers throughout the study area. This interpretation was verified by drilling three additional test boreholes in carefully selected locations.

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.

It is a truism that as the precision of geodetic measurement techniques improves, the accuracy of the geophysical modeling of processes that contribute to the observations must keep pace. Studies of the Earth's response to human-induced climate change provide many notable, and pressing, illustrations of this axiom. For example, estimates of recent ice volume changes, as inferred from satellite gravity measurements, tide gauge and satellite-altimetry records of sea level changes, or astronomical and space-geodetic constraints on Earth rotation, require improved theoretical and numerical treatments of ongoing glacial isostatic adjustment in response to the last ice age. However, the interplay between geodesy and geophysics is not a one-way street; geophysical modeling has emphasized, for example, that the geographic variability in sea level measurements - once considered a nuisance in efforts to infer long term trends - provides a powerful constraint on both the individual sources of meltwater and their sum. In this talk, I will discuss a series of case studies that demonstrate how interdisciplinary research at the interface between geodesy and geophysics has recently resolved several outstanding problems in global change research, including Walter Munk's enigma of global sea-level rise and the apparent failure to close the budget of twentieth century sea level. Moreover, in the same interdisciplinary context, I will highlight uncertainties that currently limit our understanding of polar ice sheet stability in a progressively warming world.

ZapataEngineering, Blackhawk Division performed geophysical void detection demonstrations for the US Department of Labor Mine Safety and Health Administration (MSHA). The objective was to advance current state-of-practices of geophysical technologies for detecting underground mine voids. The presence of old mine works above, adjacent, or below an active mine presents major health and safety hazards to miners who have inadvertently cut into locations with such features. In addition, the presence of abandoned mines or voids beneath roadways and highway structures may greatly impact the performance of the transportation infrastructure in terms of cost and public safety. Roads constructed over abandoned mines are subject to potential differential settlement, subsidence, sinkholes, and/or catastrophic collapse. Thus, there is a need to utilize geophysical imaging technologies to accurately locate old mine works. Several surface and borehole geophysical imaging methods and mapping techniques were employed at a known abandoned coal mine in eastern Illinois to investigate which method best map the location and extent of old works. These methods included: 1) high-resolution seismic (HRS) using compressional P-wave (HRPW) and S-wave (HRSW) reflection collected with 3-D techniques; 2) crosshole seismic tomography (XHT); 3) guided waves; 4) reverse vertical seismic profiling (RVSP); and 5) borehole sonar mapping. In addition, several exploration borings were drilled to confirm the presence of the imaged mine voids. The results indicated that the RVSP is the most viable method to accurately detect the subsurface voids with horizontal accuracy of two to five feet. This method was then applied at several other locations in Colorado with various topographic, geologic, and cultural settings for the same purpose. This paper presents the significant results obtained from the geophysical investigations in Illinois.

Extraction of hydrocarbons from reservoirs demands ever-increasing technological effort, and there is need for geophysical monitoring to better understand phenomena occurring within the reservoir. Significant deformation processes happen when man-made stimulation is performed, in combination with effects deriving from the existing natural conditions such as stress regime in situ or pre-existing fracturing. Keeping track of such changes in the reservoir is important, on one hand for improving recovery of hydrocarbons, and on the other hand to assure a safe and proper mode of operation. Monitoring becomes particularly important when hydraulic-fracturing (HF) is used, especially in the form of the much-discussed "fracking". HF is a sophisticated technique that is widely applied in low-porosity geological formations to enhance the production of natural hydrocarbons. In principle, similar HF techniques have been applied in Europe for a long time in conventional reservoirs, and they will probably be intensified in the near future; this suggests an increasing demand in technological development, also for updating and adapting the existing monitoring techniques in applied geophysics. We review currently available geophysical techniques for reservoir monitoring, which appear in the different fields of analysis in reservoirs. First, the properties of the hydrocarbon reservoir are identified; here we consider geophysical monitoring exclusively. The second step is to define the quantities that can be monitored, associated to the properties. We then describe the geophysical monitoring techniques including the oldest ones, namely those in practical usage from 40-50 years ago, and the most recent developments in technology, within distinct groups, according to the application field of analysis in reservoir. This work is performed as part of the FracRisk consortium (www.fracrisk.eu); this project, funded by the Horizon2020 research programme, aims at helping minimize the

The task of delineating the contamination plumes as well as studying their impact on the soil and groundwater biogeochemical properties is needed to support the remediation efforts and plans. Geophysical methods including electrical resistivity tomography (ERT), induced polarization (IP), ground penetrating radar (GPR), and self-potential (SP) have been previously used to characterize contaminant plumes and investigate their impact on soil and groundwater properties (Atekwana et al., 2002, 2004; Benson et al., 1997; Campbell et al., 1996; Cassidy et al., 2001; Revil et al., 2003; Werkema et al., 2000). Our objective was to: estimate the hydrocarbon contamination extent in a contaminated site in northern France, and to adverse the effects of the oil spill on the groundwater properties. We aim to find a good combination of non-intrusive and low cost methods which we can use to follow the bio-remediation process, which is planned to proceed next year. We used four geophysical methods including electrical resistivity tomography, IP, GPR, and SP. The geophysical data was compared to geochemical ones obtained from 30 boreholes installed in the site during the geophysical surveys. Our results have shown: low electrical resistivity values; high chargeability values; negative SP anomalies; and attenuated GPR reflections coincident with groundwater contamination. Laboratory and field geochemical measurements have demonstrated increased groundwater electrical conductivity and increased microbial activity associated with hydrocarbon contamination of groundwater. Our study results support the conductive model suggested by studies such as Sauck (2000) and Atekwana et al., (2004), who suggest that biological alterations of hydrocarbon contamination can substantially modify the chemical and physical properties of the subsurface, producing a dramatic shift in the geo-electrical signature from resistive to conductive. The next stage of the research will include time lapse borehole
In Germany Geophysics is a science with almost none or a bad reputation. People do not know to distinguish between Geophysics, Geography and Geology. In order to change the public view on Geosciences, a,School Project Geophysics' is going to be created at the Institute of Meteorology and Geophysics, Johann Wolfgang Goethe University, Frankfurt, which will offer geophysical ideas, methodes and scientific results to schoolclasses. After researches like PISA or TIMSS (third international Math and Nature-Science test) new concepts in education will be required. Interdisciplinary tasks are demanded by national and international commissions.\\The,School Project Geophysics' will be created to bring geophysical themes and results of scientific research into schools. One Day- or one Week-Workshops will help to publish geophysical contents in close cooperation with Physics - and Geography - teachers.\\Hands-on experiments (for advanced pupils) like refraction-Seismics or Magnetic measurements will lead students closer to scientific work and will help to establish personal interests in Earthsciences. Working with personally produced datasets will show the basics of inversion theory and point out the difficulties in creating models. Boundaries of data interpretation (the plurality of variables needed) will teach the school children to see scientific and statistic predictions and declarations more criticaly. Animations and Videos will present global examples (for example of volcanoes or Earthquakes) and lead over to regional sites. Excursions to these sites will help to show fieldwork methods and its problems and will convince to take a different look on topography and landscapes.\\All necessary utilities (Animations, Videos, Pictures and foils) will be offered to teachers in an online-data base which will be installed and managed by the project. Teachers and pupils might get easily into contact with Scientists to discuss geoscientific items. Further on extensions to geographic

Man-made vitreous (glass-like) fibres are non-crystalline, fibrous inorganic substances (silicates) made primarily from rock, slag, glass or other processed minerals. These materials, also called man-made mineral fibres, include glass fibres (used in glass wool and continuous glass filament), rock or stone wool, slag wool and refractory ceramic fibres. They are widely used for thermal and acoustical insulation and to a lesser extent for other purposes. These products are potentially hazardous to human health because they release airborne respirable fibres during their production, use and removal. Man-made mineral fibres and man-made vitreous fibres have been the subject of reviews by IARC Monographs Working Groups in 1987 and 2001, respectively, which resulted in evaluations of the carcinogenic hazard to humans from exposure to these materials. These reviews and evaluations have been published as Volumes 43 and 81 of the IARC Monographs series [IARC Monographs on the Evaluation of Carcinogenic Risks to Humans, vol. 43, Man-made Mineral Fibres and Radon (1988); IARC Monographs on the Evaluation of Carcinogenic Risks to Humans, vol. 81, Man-made Vitreous Fibres (2002)]. The re-evaluation in 2001 was undertaken because there have been substantial improvements in the quality of the epidemiological information available on the carcinogenicity to humans of glass fibres, continuous glass filament and rock/slag wool. The new evaluations have addressed the limitations of earlier cohort studies, particularly concerning the lack of adjustment with respect to concomitant risk factors such as smoking and other sources of occupational exposure. In addition, the evaluation of the evidence for carcinogenicity of glass fibres to experimental animals has been refined, by making a distinction between insulation glass wool and special-purpose glass fibres. The results of the evaluations in 1987 and 2001 are thus different in several aspects. In this paper, the reviews and evaluations

Infrastructure, such as road transportation, is a vital in civilized societies; which need to be constructed and maintained regularly. A large part of the project cost is attributed to subsurface conditions, where unsatisfactory conditions could increase either the geotechnical stabilization measures needed or the design cost itself. A way to collect information of the subsurface and existing installations which can lead to measures reducing the project cost and damage is to use geophysical methods during planning, construction and maintenance phases. The moisture in road layers is an important factor, which will affect the bearing capacity of the construction as well as the maintenances. Moisture in the road is a key factor for a well-functioning road. On the other hand the excessive moisture is the main reason of road failure and problems. From a hydrological point of view geophysical methods could help road planners identify the water table, geological strata, pollution arising from the road and the movement of the pollution before, during and after construction. Geophysical methods also allow road planners to collect valuable data for a large area without intrusive investigations such as with boreholes, i.e. minimizing the environmental stresses and costs. However, it is important to specify the investigation site and to choose the most appropriate geophysical method based on the site chosen and the objective of the investigation. Currently, numerous construction and rehabilitation projects are taking places around the world. Many of these projects are focused on infrastructural development, comprising both new projects and expansion of the existing infrastructural network. Geophysical methods can benefit these projects greatly during all phases. During the construction phase Ground Penetrating radar (GPR) is very useful in combination with Electrical Resistivity (ER) for detecting soil water content and base course compaction. However, ER and Electromagnetic

This paper presents a review of geophysical methods used at Hanford in two parts: (1) shallow surface-based geophysical methods and (2) borehole geophysical methods. This review was not intended to be ``all encompassing'' but should represent the vast majority (>90% complete) of geophysical work conducted onsite and aimed at hazardous waste investigations in the vadose zone and/or uppermost groundwater aquifers. This review did not cover geophysical methods aimed at large-scale geologic structures or seismicity and, in particular, did not include those efforts conducted in support of the Basalt Waste Isolation Program. This review focused primarily on the more recent efforts.
Three sessions at international conferences were held in 1997 to discuss the history of space and geophysics and its different disciplines. The first session was held during the Assembly of the German Geophysical Society in March in Potsdam, Germany. Topics included the theory of relativity and gravitation in geophysics; work by Albert Abraham Michelson, Leon Foucault, and Ernst Mach; work by Hermann von Helmholtz; and the physical application and geophysical evidence of Werner Heisenberg's research. Also included were discussions relevant to the history of geophysics, aeronomy, meteor astronomy, and geodetical research, including developments in instrumentation during the last few decades.

The Geophysical Fluid Flow Cell (GFFC) experiment performed visualizations of thermal convection in a rotating differentially heated spherical shell of fluid. In these experiments dielectric polarization forces are used to generate a radially directed buoyancy force. This enables the laboratory simulation of a number of geophysically and astrophysically important situations in which sphericity and rotation both impose strong constraints on global scale fluid motions. During USML-2 a large set of experiments with spherically symmetric heating were carried out. These enabled the determination of critical points for the transition to various forms of nonaxisymmetric convection and, for highly turbulent flows, the transition latitudes separating the different modes of motion. This paper presents a first analysis of these experiments as well as data on the general performance of the instrument during the USML-2 flight.

Modern space geodetic measurement of Earth rotation variations, particularly by means of the VLBI technique, has over the years allowed studies of Earth rotation dynamics to advance in ever-increasing precision, accuracy, and temporal resolution. A review will be presented on our understanding of the geophysical and climatic causes, or "excitations". for length-of-day change, polar motion, and nutations. These excitations sources come from mass transports that constantly take place in the Earth system comprised of the atmosphere, hydrosphere, cryosphere, lithosphere, mantle, and the cores. In this sense, together with other space geodetic measurements of time-variable gravity and geocenter motion, Earth rotation variations become a remote-sensing tool for the integral of all mass transports, providing valuable information about the latter on a wide range of spatial and temporal scales. Future prospects with respect to geophysical studies with even higher accuracy and resolution will be discussed.

The evolution of Earth-like habitable planets is a complex process that depends on the geodynamical and geophysical environments. In particular, it is necessary that plate tectonics remain active over billions of years. These geophysically active environments are strongly coupled to a planet's host star parameters, such as mass, luminosity and activity, orbit location of the habitable zone, and the planet's initial water inventory. Depending on the host star's radiation and particle flux evolution, the composition in the thermosphere, and the availability of an active magnetic dynamo, the atmospheres of Earth-like planets within their habitable zones are differently affected due to thermal and nonthermal escape processes. For some planets, strong atmospheric escape could even effect the stability of the atmosphere.

The importance of a precise, high resolution gradiometric and magnetometric mission in some topics of geophysical interest is stressed. Ways in which the planned Aristoteles mission can allow the geophysical community to improve the knowledge and the physical understanding of several important geodynamical processes involving the coupled system consisting of the lithosphere, asthenosphere and upper mantle are discussed. Particular attention is devoted to the inversion of anomalous density structures in collision and subduction zones by means of the joint use of gradiometric and seismic tomographic data. Some modeling efforts accomplished to study the capability of the mission to invert the rheological parameters of the lithosphere and upper mantle through the gravimetric signals of internal and surface density anomalies are described.

Geophysics provides useful tools for monitoring water infiltration in soil essentially because they are non-invasive and have a good time-resolution. We present some results obtained on different soils using two geophysical techniques: electrical resistivity tomography (ERT) and ground-penetrating radar (GPR). Infiltration in a loamy soil was monitored using a 2D Wenner array set up under a tension disc infiltrometer. A good imaging of the infiltration bulb below the infiltrometer could be achieved provided a sufficient resistivity contrast between the wet and the dry soil zones. ERT data could be used to invert soil hydraulic properties. However, we found that the information provided by the ERT could be of limited importance in regard to the information provided by the infiltration rate dynamics if the ERT spatial resolution is not small enough to capture the details of the infiltration front at the limit between the wet and dry soil zones. GPR was found to be a good tool to monitor the progression of the infiltration front in a sandy soil. By combining a water transport simulation model (HYDRUS-1D), a method for transforming water content into dielectric permittivity values (CRIM), and an electromagnetic wave propagation model (GprMax), the Mualem-van Genuchten hydraulic parameters could be retrieved from radargrams obtained under constant or falling head infiltration experiments. Both ERT and GPR methods have pros and cons. Time and spatial resolutions are of prime importance to achieve a sufficient sensitivity to all soil hydraulic parameters. Two exploration fields are suggested: the combination of different geophysical methods to explore infiltration in heterogeneous soils, and the development of integrated infiltrometers that allow geophysical measurements while monitoring water infiltration rate in soil.
