The Wash-Out of Organic Carbon from Degrading Shores and its Distribution at the Under-Water Coastal Slope (the Buor-Khaya Peninsula, the Laptev Sea)

摘要

The active supply of clastic organic carbon to the Arctic basin from degrading sea shores draws serious attention of many researchers because it serves as a greenhouse gas source. It was found out that the shores composed of the ice complex and alas deposits are the main sources of organic carbon in the East-Siberian Arctic Region [Kholodov 2003; Grigoriev et al. 2004]. The purpose of this research consisted in the evaluation of the quantity of organic carbon (Сorg) supplied to the Buor-Khaya Gulf as a result of thermal abrasion and thermal denudation destruction of the Buor-Khaya Peninsula western shore and identification of the peculiarities of the Сorg distribution in bottom sediments at the under-water coastal slope.
