Based on a recommendation from the Biological 

 Oceanography Workshop held in 1981, a radiological 

 data base was issued (SAND 83-1725, September 

 1983). This compilation is being used to provide 

 data as input for the foodweb model. The report 

 has also identified gaps in the existing data. We 

 hope to fill these data gaps during the expanded 

 program starting in FY 1985. International studies 

 which provide data to the US program include: 

 monitoring of the Nuclear Energy Agency low-level 

 nuclear waste dump site in the Northeast Atlantic 

 Ocean, analysis of the migration patterns of 

 deep-ocean nekton. These studies are providing 

 data which are being used in the biological 

 modeling effort. 



In addition to the foodweb transport model, the 

 Subseabed Disposal Program has begun work on a 

 deep-sea carbon model. This model will identify 

 the biological processes which may be important in 

 transporting nuclides from the deep ocean to man. 

 These data can then be used in human population 

 dose critical patnways analysis.
