Research on the Fate of Radionuclides in the Arctic Marine System

AGENCY: Department of Defense-Navy

PROGRAM: Radionuclide contamination of the marginal seas of the Arctic Ocean from activities of the Former Soviet Union is of increasing concern. Several dump sites for nuclear reactors and other wastes have been identified in the Barents and Kara Seas, and many of the rivers discharging sources into the Arctic may be seriously polluted. Less information is available on sources in the western Arctic. Although the levels of radionuclides in Alaskan waters are currently low and levels in the eastern Arctic have decreased in recent years due to cessation of leakage, both sustained and catastrophic, must be considered. Such releases could result from breaching of watershed impoundments on rivers and from corrosion of containers dumped in the sea. This announcement advocates programs of research that will improve understanding in one or more of the following areas: 1) quantification of the types, amounts and rates of release of radionuclides from marine disposal sites and riverine sources based on integration and analysis of existing data; 2) transport pathways and fate of radionuclides through the Arctic marine ecosystem including physical processes, concentration mechanisms in organisms and geochemical cycling; and 3) long term monitoring strategies including site selection and sampling methods.

QUALIFICATIONS: Cooperative investigations including FSU scientists are particularly encouraged.
