Purpose. The purpose of the study is to investigate distribution of Cs-137 in the coastal and deep-water part of the Black Sea. To achieve this goal, the following scientific problems has to be solved: choosing a method for concentrating Cs-137 from seawater samples, seawater sampling and Cs-137 concentrating, measurements of the obtained samples, discussion of the obtained results and their comparison with the available scientific literature data. Materials and Results. Distribution of Cs-137 activity in the coastal and deep-water part of the Black Sea was studied. The in situ data on spatial-temporal variability of the Cs-137 volumetric activity field in the Black Sea surface layer obtained in course of the 95th cruise of the R/V "Professor Vodyanitsky" in June, 14-July 7, 2017 were used. The data on the radionuclide vertical distribution in the sea active layer were obtained at a number of stations. 22 seawater samples were taken and processed at 11 stations. To separate Cs-137 from seawater, a ferrocyanide sorbent of the FCC brand was first applied; it was intentionally developed for selective recovery and separation of Cs-134 and Cs-137 radionuclides from the technological processing solutions and radioactive waste water. Conclusions. According to the results, the volumetric activity of Cs-137 varied spatially in the range 5.7-8.8 Bq/m(3) and amounted on average 6.9 +/- 0.2 Bq/m(3). Within the active layer boundaries, vertical distribution of Cs-137 was found to be uniform
