GEOLOGICAL RESEARCHES IN THE EAST SIBERIAN AND LAPTEV SEAS DURING THE 4th STAGE OF THE TRANSARCTIC-2019 EXPEDITION
Information is given on geological work in the East Siberian and Laptev Seas carried out as part of the 4th stage of the Transarctic-2019 expedition (September 11-23, 10, 2019). Most of the work was carried out in the East Siberian Sea, which was studied relatively little from a geological and paleo-oceanological point of view, which was completely ice-free during the expedition. Sediment cores from various sections of the shelf and the continental slope were selected for subsequent analysis and study with the aim of reconstructing the changes in the paleoenvironment in the Late Pleistocene and Holocene and geological mapping.
