    American Geophysical Union (AGU) is an international scientific society of 39,000 members, more than thirty percent of whom come from outside the U.S. As a society AGU is dedicated to advancing the understanding of Earth and its environment in space and making results availableto the public.

    The European Union of Geosciences (EUG), started in 1980. Its aim is to develop cooperation among scientists in different fields of earth and planetary sciences such as geology, geophysics, geochemistry, planetology, oceanography, hydrology, etc. Its membership is strictly individual and no one may represent any national organization, institution, or laboratory.

    The Geochemical Society(GS) is a private nonprofit international scientific society founded to encourage the application of chemistry to the solution of geological and cosmological problems. Membership is international and diverse in background, encompassing such fields as organic geochemistry, high- and low-temperature geochemistry, petrology, meteoritics, fluid-rock interaction, and isotope geochemistry.

    The Mineralogical Society of America (MSA) provides a forum for individuals interested in mineralogy, crystallography, and petrology.

    Spring Meeting Returns to Washington, D.C.

    Washington, D.C., capital city of the United States of America, is not just a place for politics, history, and monuments. Beyond some of its most famous landmarks (the White House, U.S. Capitol, Washington Monument, Vietnam War Memorial, and Arlington National Cemetery), Washington, D.C. offers visitors a wealth of natural beauty, architecture, and culture, including the Potomac River, parks, museums, embassies, galleries, universities, historic neighborhoods, unique shops, restaurants, theatres, and clubs. There has never been a more exciting time to visit this exciting international city!

    Scientific sessions will be held at the Washington Convention Center, 900 Ninth Street, NW, Washington, D.C.

    This NASA Earth Science Town Hall Meeting will have two parts. The first part, "NASA Earth Science Vision 2010-2025," will introduce AGU members to the ongoing Earth Science Vision activities aimed at framing big questions on which to focus NASA's Earth Science research in the 2010-2025 period. A small team has worked for 6 months to create these questions, which are designed to be revolutionary, deep, of long-term benefit to society, specific (yet rainmakers for a broad range of subjects), and which require the types of measurement systems NASA builds. There are five teams: Extreme Weather; Medium-Term Climate; Long-Term Climate; Biosphere, Ecosystems, and Human-Biosphere Interactions; and Solid Earth, Ice Sheets, and Sea Level. Each team has produced one primary and one secondary question, with each question receiving a complete end-to-end treatment including requirements for necessary observations, modeling, application support, and information systems. An overview talk will be followed by five short talks from the leaders of each team and a general discussion period. The second part of the Town Hall Meeting, "An update on Future NASA Earth Science Initiatives and Missions," will be devoted to an update on activities in the period up to 2010 including planned missions and research initiatives like Carbon Cycle and Global Water and Energy.

Current and past fellows from both of these programs will share their experience and answer your questions. Mass Media Fellows report on and write about science news for a newspaper, magazine, or radio or TV station for a 10-week period during the summer. Congressional Science Fellows deal with science issues in the office of a senator, representative, or committee for a full year. Space is limited. Lunch provided (first come, first serve).

    Kennedy Center Performances

    Tickets are still available for two performances at the Kennedy Center during the Spring Meeting. To place your order for tickets, contact the AGU Meetings Department, Tel: +1-202-777-7332, Fax: +1-202-328-0566. There are no refunds for Kennedy Center tickets.

    Field Trips

    Two field trips, sponsored by the AGU Biogeosciences Section, will be offered to research sites in the Washington, D.C. area, Saturday, 1 June 2002, 8:00 A.M.-4:00 P.M.

    Each field trip is limited to 20 participants and will include lunch and transportation ($35 per person). To reserve a space, please contact the AGU Meetings Department, Tel: +1-202-777-7332, Fax: +1-202-328-0566.

    Baltimore Ecosystem Study
    The Baltimore Ecosystem Study aims to understand Baltimore as an ecological system and to determine how the ecosystem changes over long time periods. Participants will visit a set of small catchments and experimental plots located in forested, agricultural, suburban, and urban land uses. Participants will view measurements and results from a set of ecosystem plots and catchment-scale studies that focus on storage and fluxes of terrestrial carbon, water, and nutrients. The trip will be led by Larry Band from the University of North Carolina and Peter Groffman from the Institute of Ecosystem Studies.

    Smithsonian Environmental Research Center
    The Smithsonian Environmental Research Center (SERC) is dedicated to increasing knowledge of the biological and physical processes that sustain life on earth. SERC's interdisciplinary research applies long-term studies to examine ecological questions about landscapes of linked ecosystems, especially those impacted by human activities. Located on the shore of Chesapeake Bay in Edgewater, Maryland, SERC uses the geographic features of the nation's largest estuary to investigate interconnections of aquatic, terrestrial, and atmospheric components of complex landscapes, which are then compared on regional, continental, and global scales. Participants will view measurement sites for specific field-based research projects, including the response of a salt marsh ecosystem to elevated CO2, nutrient export from a riverine ecosystem to the Chesapeake Bay, and the effects of ultra-violet radiation on plankton. The field trip will be led by Patrick Magonigal, a research scientist at SERC.
