Abstract. Expeditions carried out in 2017 and 2018 in the north of the Kara and Laptev seas by the FSBI “VNIIOkeangeologia” was realized as part of the “Program of State geological mapping of the territory and continental shelf of the Russian Federation”. The columns of bottom sediments are dated, which indicate favorable conditions for benthos about 9000 years ago.

Keywords: geological survey of the shelf, Neopleistocene, Holocene, radiocarbon dating, continental slope, Voronin trough, Kara Sea, Laptev Sea
