Abstract
The sedimentation rate is an important factor influencing the quantitative distribution and composition of sedimentary material, the thickness of bottom sediments, and the dynamics of their transformation at the early diagenesis stage [1]. In [2‐4], the average sedimentation rates were largely determined for the entire Sea of Azov using calculation methods (balance method and comparison between bathymetric charts). At the same time, subsequent natural and anthropogenic changes that occurred in the Don and Kuban river basins resulted in reorganization of the structure and dynamics of water masses, salinity, and sedimentary matter fluxes. In this connection, additional study of the spatial distribution and dynamics of sedimentation rates by advanced methods is needed. During several expeditions conducted in 2006 and 2007, bottom sediments were taken by a gravity corer (designed by the State Oceanographic Institute) and sampled in the layer-by-layer manner at ten stations located in the Russian segment of the Sea of Azov and mouth areas of the Don and Kuban rivers. The maximal length of cores is 100 cm [5]. In total, the activity of 137 Cs and 241 Am radionuclides was measured in over 60 samples. Technogenic radionuclides presently contained in
