- Аннотация: The spatial distribution of 7 Be activity in the surface layer of the Black Sea was studied using the data of field observations made during the 87th cruise of R/V Professor Vodyanitskii. Activity of 7 Be varied spatially from 4.6 to 9.5 Bq m −3 (mean 7.5 ± 1.3 Bq m −3 ) where about 9% was found on suspended matter. The minimum values of activity were typical for samples taken in the shelf waters and the maximum—offshore. The influence of different factors on 7 Be activity was analyzed. It was revealed that variation of both 7 Be wet deposition on the sea surface and concentration of suspended matter were the most significant for spatiotemporal variability of 7 Be activity in seawater during the study period. The estimates of 7 Be distribution coefficient between dissolved and particulate forms were obtained. This coefficient varied from 1.5·10 5 to 2.4·10 5 L kg −1 , averaged (1.9 ± 0.3)·10 5 L kg −1 .
