Preliminary results of the study of sedimentation in the Central Depression of the Barents Sea

Abstract

The article represents the results of the study of bottom sediment cores taken from the R/V “Dalnie Zelentsy” in the Central Depression of the Barents Sea during the 2022 expedition. The exposed stratum of bottom sediments is composed of silty-pelitic material, in some layers there is an admixture of uneven-grained sand and grains of well-rounded gravel. The chronology of sedimentation was determined by changing the specific activity of excess 210Pb, the obtained data were verified by 137Cs. The rate of sedimentation in the study area over the past 120 years has varied within 0.05–0.1 cm/year.
