Relief of the Kara Sea Bottom and Sediments Sorption Properties as Factors of Pollution Accumulation
The article presents a modern “Geomorphological map of the Kara Sea bottom” on a scale of 1 : 2 000 000 and its description. The creature of this map was carried out on the basis of the “Bathymetric map of the Kara Sea” of the same scale, created from large-scale (1 : 200 000 and 1 : 500 000) nautical charts. On the basis of these maps and data of silicate analysis of samples of the upper sediment layer, a “Scheme of the relative sorption capacity bottom sediments of the western part of the Kara Sea”, which illustrates the position of the regions most prone to the sorption of pollutants. An integrated approach to the study of migration and accumulation of pollutants in marine ecosystems is proposed, combining the main factors affecting their accumulation in bottom sediments: geomorphological characteristics of the bottom, sorption parameters of precipitation, the role of geochemical barrier zones.
