First Results of the Comprehensive Analysis, Including the Paleomagnetic Studies, of Sediment Cores from the East Siberian Sea

The bottom sediments of the Russian Arctic seas have been studied to varying degrees. The least attention has been paid to the East Siberian Sea, the Quaternary geology of which remains largely overlooked. This article summarizes the results of a comprehensive research on the East Siberian Sea, including the first paleomagnetic analysis of nine sediment cores collected during three cruise expeditions as part of the program "State Geological Mapping of the Territory and Continental Shelf of the Russian Federation at the Scale of 1:1 000 000". The results obtained show that the processes and conditions of sedimentation vary in different parts of the East Siberian Sea.
