The seasonal dynamics of biogenic sedimentation in Sevastopol Bay, Black Sea, was studied using thorium-234 (234Th) as a natural radiotracer. The percentage content of biogenic particulate matter in bottom sediments was determined based on the 40K ra

Most of the hypersaline lakes located in the arid part of the Crimea have been undergoing anthropogenic transformations. We concentrate on the impact of the established water storage reservoir on the marine Kyzyl-Yar Lake (Western Crimea) over the pe

The phytoplankton primary production and the biogenic elements content of the coastal waters off Sevastopol have been studied as a result of 2-year monitoring. It has been found that mineral phosphorus is a key factor of chemical limitation of the pr

Sevastopol Bay is used as an example for the development of criteria for rating anthropogenic impact by elimination fluxes from the water area of post-Chernobyl (90Sr, 137Cs, 239,240Pu) and natural (210Pо) radionuclides, as well as mercury and organ

The bacterial utilization of organic matter was investigated during two cruises made in the north-western Black Sea in the summer of 1995 and in the winter-spring transition period (April-May 1997). Bacterial biomass and activities (enzymatic activit
