E-MAIL: Dr. John Marra, jmarra@hq.nasa.gov. The National Aeronautics and Space Administration (NASA) intends to solicit proposals for scientific investigations and activities contributing to the Oceanography Program. The Oceanography and Polar Programs at NASA's Earth Science Enterprise (ESE) contribute to the research themes, the biology and biogeochemistry of ecosystems and the global carbon cycle, and climate variability. This NRA solicits investigations in the areas of (1) analysis and interpretation of ocean processes using satellite, aircraft, and in situ data, (2) multi-sensor approaches to understanding ocean phenomena, (3) understanding and estimation of air-sea fluxes, (4) providing the scientific basis for next-generation ocean remote sensing technologies, (5) temporal and spatial variability of primary productivity and new production in the ocean, (6) identification of phytoplankton taxonomic groups from space or airborne sensors, (7) investigating and evaluating oceanographic links between high latitude climate and lower latitude climate, and (8) development and demonstration of data assimilation techniques for the improvement of polar ocean and sea ice models. The present announcement is for the selection of investigations to be carried out for a period of 3 years. Current investigators on the SeaWiFS Science Team who wish to continue their membership on the Team with NASA support must propose to do so in response to this NRA. Other interested parties are also invited to propose. The NRA will be available electronically on the release date, via the Internet at the Earth Science Enterprise ''Home Page'' at '' http://www.earth.nasa.gov '' under ''Research Opportunities'' . A paper copy will be available to those who do not have access to Internet by calling (202) 358-3552 and leaving a voice mail message. This announcement will be open for the period from May 26 through July 26, 2000, and proposals may be submitted at any time throughout that period. Posted 05/10/00 (D-SN453413). (0131)
