  • Net annual soil carbon change, fossil fuel emissions from cropland production, and cropland net primary productivity were estimated and spatially distributed using land cover defined by the Moderate Resolution Imaging Spectroradiometer (MODIS) and by the Cropland Data Layer (CDL). Spatially resolved estimates of net ecosystem exchange (NEE) and net ecosystem carbon balance (NECB) were developed. NEE represents net on-site vertical fluxes of carbon. NECB represents all on-site and off-site carbon fluxes associated with crop production. Estimates of cropland NEE using moderate resolution (~1km2) land cover data were generated for the conterminous US and compared with higher resolution (30m) estimates ofmore » NEE and with direct measurements of CO2 flux from croplands in Illinois and Nebraska. Estimates of NEE using the CDL (30m resolution) had a higher correlation with eddy covariance flux tower estimates compared with estimates of NEE using MODIS. Estimates of NECB are primarily driven by net soil carbon change, fossil-fuel emissions associated with crop production, and CO2 emissions from the application of agricultural lime. NEE and NECB for US croplands were -274 and 7 Tg C yr-1 for 2004, respectively. Use of moderate to high resolution satellite-based land cover data enables improved estimates of cropland carbon dynamics.« less
  • The U.S. Department of Energy (DOE) has a rich history of significant contributions to geospatial science spanning the past four decades. In the early years, work focused on basic research, such as development of algorithms for processing geographic data and early use of LANDSAT imagery. The emphasis shifted in the mid-1970s to development of geographic information system (GIS) applications to support programs such as the National Uranium Resource Evaluation (NURE), and later to issue-oriented GIS applications supporting programs such as environmental restoration and management (mid-1980s through present). Throughout this period, the DOE national laboratories represented a strong chorus of voicesmore » advocating the importance of geospatial science and technology in the decades to come. The establishment of a Geospatial Science Program by the DOE Office of the Chief Information Officer in 2005 reflects the continued potential of geospatial science to enhance DOE's science, projects, and operations, as is well demonstrated by historical analysis.« less
  • For many decades, the Department of Energy (DOE) has been a leader in basic scientific and engineering research that utilizes geospatial science to advance the state of knowledge in disciplines impacting national security, energy sustainability, and environmental stewardship. DOE recently established a comprehensive Geospatial Science Program that will provide an enterprise geographic information system infrastructure connecting all elements of DOE to critical geospatial data and associated geographic information services (GIServices). The Geospatial Science Program will provide a common platform for enhanced scientific and technical collaboration across DOE's national laboratories and facilities.

  • The Department of Energy will continue to deliver isotope goods and services that contribute to health, well-being, and quality of life. In cooperation with its customers, stakeholders, and the public, the department has established an isotope policy that addresses the two distinct parallel needs associated with isotope availability: the need to support the research and development community with isotopes for which there are no other reliable supplies; and the need to assure a reliable and competitive supply of isotopes for which a infrastructure and market have been developed. In the face of many challenges the department`s isotope program is activelymore » pursing a course which will provide isotope customers a reliable supply at the least cost. Operating efficiency is being improved though process improvement initiatives, upgrading facilities, dual site production, and seeking to remove the uncertainty from production costs. These factors may cause some upward impact on isotope costs, but will provide better products and services to the customers.« less
