First data of modern sedimentation rate in the southern tatar strait of the sea of japan

The study of natural archives, such as bottom sediments of lakes and seas, becomes promising for paleoreconstructions due to the conditions of rapid changes of the environment, anthropogenic impact, and insufficient data of instrumental measurements. Based on a radioisotope dating using the non-equilibrium 210Pb, the modern sedimentation rates for the last 150 years in the southern part of the Tatar Strait have been established. According to the two models (CIC and CRS), the sedimentation rate was 0.20–0.22 сm/year.
