National Science Foundation

Areas of Global Change Research. NSF global change research programs support research and related activities that advance fundamental understanding of dynamic physical, biological, and socio-economic systems, and the interactions among those systems. In addition to research on Earth system processes and the consequences of changes in those systems, NSF programs facilitate data-acquisition and data-management activities necessary for basic research on global change, promote the enhancement of modeling designed to improve representations of Earth system interactions, and develop advanced analytic methods to facilitate fundamental research. NSF also supports fundamental research on the general processes used by governments and other organizations to identify and evaluate different types of policies for mitigation, adaptation, and other responses to changing global environmental conditions.

FY98 Program Highlights. During FY98, NSF will continue to support research and related activities across all of its global change programs. A significant share of the agency’s efforts will focus on continuation of major international collaborative field programs. Of these programs, the World Ocean Circulation Experiment (WOCE) and the Joint Global Ocean Flux Study (JGOFS) are phasing down field observations and moving toward intensive analysis and synthesis. Modest growth is expected for research related to Global Ocean Ecosystem Dynamics (GLOBEC) and Earth System History (ESH), among other, programs. GLOBEC expansions will support studies from the Atlantic to the Pacific Ocean, with special focus on sensitivity of target species to global changes and analysis of ecosystem productivity and interactions. Growth related to ESH will allow for international collaboration between ESH scientists and the International Marine Past Global Changes Study (IMAGES) on high accumulation ocean sediment from the Indo-Pacific region. ESH-sponsored scientists also will collaborate with the International Continental Drilling Program for recovery and analysis of long, high-resolution sediment cores and with CLIVAR scientists for recovery and analysis of paleo-environmental records on seasonal to century time scales. In FY98, continued support for CLIVAR activities will sponsor research aimed at the improvement of seasonal-, interannual-, and decadal-scale climate understanding and prediction.

NSF will continue to support the development, testing, and application of climate system models and improved methods to enhance model representations of related Earth processes. In support of this work, NSF plans to enhance the development and application of the community-use Climate System Model (CSM) at the National Center for Atmospheric Research (NCAR). Consistent with this plan, NSF will continue to make available advanced computational facilities for USGCRP-sponsored Earth system modeling. NSF also will maintain support for research on fundamental understandings of human contributions and responses to global change as well as research on ecological dynamics and consequences of global environmental change.

Related Research. In addition to focused research, NSF conducts contributing research on many topics, including laboratory and field studies of the atmosphere and the factors that affect it; data management for scientific research and modeling activities; generation, transportation, and fate of chemicals in natural systems; long-term monitoring and detailed studies of ecosystems; geophysical, hydrological, geological, and geochemical processes operating on the Earth’s surface; composition, structure, and history of ocean floors; and global environmental history.

Mapping of Budget Request to Appropriations Legislation. In the Departments of Veterans Affairs and Housing and Urban Development, and Independent Agencies Appropriations Bill, National Science Foundation USGCRP activities are funded under the NSF section of Title III-Independent Agencies, within the NSF Research and Related Activities account.
