Abstract:

The contribution of atmospheric aerosols to the content of four trace elements (nickel, lead, zinc, and cadmium) in the Arctic Ocean and its seas has been evaluated. It is shown that this contribution compares well with the contribution coming from river suspension (after passing through marginal filters) of inflowing rivers. In the water of the Kara Sea, Laptev Sea, and East- Siberian Sea, the atmospheric contribution of lead and cadmium is 15-17% of the contribution from river waters, and for the whole ocean, these contributions are about the same. In waters of Chukchi Sea the content of lead and cadmium is determined to a greater extent by vertical air flows, whose contribution is several times greater than the contribution from river run-off.
