Sedimentation systems definition of the Barents Sea and Norwegian-Greenland basin during 68th cruise of the research vessel Academic Mstislav Keldysh

Abstract

The article presents summary of the first research results of sedimentation systems of the region of interaction of the Arctic Ocean and Atlantic Ocean obtained in July-August 2017. Joint examination of the system of dispersed sedimentary matter (aerosols, suspended particulate matter, phytoplankton, faecal pellets, etc.) – concentrated sedimentary matter (bottom sediments), of biogeochemical processes of the matter transformation in the system in line with paleo-oceanologic reconstructions allow us to understand environment and climate of different geological epoch in one of the key ocean areas. The attempt to study the role of endogenous material in recent sedimentation processes in the ocean was taken on the example of the subpolar zone of the mid-ocean ridges system – Mohn Ridge.
