Abstract
The latitudinal distribution of the anthropogenic radionuclide 137Cs in the Atlantic surface waters was studied according to the results of expeditionary research carried out during 79 cruise of the R/V «Akademik Mstislav Keldysh» (March-May 2020). Radiospectrometric analysis of the samples showed that the 137Cs activity concentration in the Atlantic Ocean water was in the range of 0.65 ± 0.10–1.44 ± 0.21 Bq/m3. It was found that the 137Cs activity peaks corresponded to the global fallout peaks in the middle latitudes of the Earth. Comparison of the data obtained in 2020 with the results of the 1988/1989, 1992/1993, 2002 expeditions revealed a tendency to smooth out the 137Cs activity peaks in the middle latitudes due to hydrodynamic processes in the World Ocean.
