Input flows of radionuclides, heavy metals, and oil hydrocarbons

Source Flow into the basin (km3/yr) Concentration of pollutant  

Local variations in the vertical distribution of radionuclides are determined by both hydrological and ecological conditions. The correlation between these conditions is a function of the season. Table 6.12 gives estimates of the role of ecological processes in the formation of the vertical distribution of the radionuclear pollution of Arctic seas. These estimates show that the biological community plays a minor role in radionuclide transport from upper layers to the deep ocean. 

The aquatories of the White, Laptev, East Siberian, and Chukchi Seas are subject to visible variations in radionuclear pollution. The accumulation of radionuclides is observed in the Central aquatory of the Arctic Basin. The aquageosystems of the Greenland and Kara Seas have currently unknown factors that allow radionuclear
