Abstract

Freshwater in the Arctic seas is an important factor in the circulation of water masses and the functioning of the marine ecosystem. The Kara Sea is a unique object of interaction between sea waters and freshwaters of different genesis. The paper presents the results of calculating the percentage contribution of freshwater of different origin to the surface desalinated layer using hydrochemical parameters. The structure of the surface desalinated layer in different seasons is considered. The predominance of meltwater and river waters of the Ob’ and Yenisei was noted, depending on the observation period. The variability of the structure of the surface layer and the redistribution of freshwater during the ice-free period are shown.
