 Group ot Experts on the Scientific Aspects 



ot Marine Pollutions (GESAMP) 



GESAMP IS an advisory body consisting of specialized experts 

 nominated by Sponsoring Agencies (.IMO, IAEA, UN, UNEP, FAO, UNESCO, 

 WMO, WHO). Its principal task is to provide scientific advice on 

 marine pollution problems to the Sponsoring Agencies and to the 

 Intergovernmental Oceanographic Committee (IOC). Over the last 10 

 years GESAMP has produced about 20 reports on various ocean pollution 

 topics. The most recent 1983 report, of interest to EPA regarding 

 ocean disposal of radioactive materials, is Report and Studies No. 19, 

 "An Oceanographic Model for the Dispersion of Wastes Disposed of in 

 Deep Sea." This report is the result of a 1980 request by the IAEA for 

 GESAMP to provide advice on the most suitable oceanographic models that 

 would apply to sea dumping of not only radioactive, but also other 

 hazardous wastes. The tasks were 1) to review present knowledge of 

 pathways by which substances might be transferred from a deep ocean 

 area back to man, 2) to recommend methods for calculating 

 concentrations of substances released from containers to the water 

 througnout an ocean basin, and 3) to assess the reliability of these 

 calculations. This report will be a primary reference in the IAEA 

 review of the oceanographic basis for the definition of high level 

 radioactive wastes at the Vienna meeting on November 28, as mentioned 

 earlier.
