Abstract
Using the data of long-term observations of the Secchi disk visibility depth and water salinity (1947-2000) and satellite monitoring of chlorophyll a concentration (1978-1986), their seasonal spatial distributions and intraannual variability in the coastal waters of the western Black Sea are considered. The estimates of seasonal variations are obtained for the coastal zone of the sea. A good agreement is demonstrated between intraannual variations in the salinity of transformed river water, chlorophyll a concentration, and transparency in the areas where these waters propagate. We studied the effects of the Danube River runoff and transformed river water on the phytoplankton development and chlorophyll a concentration which largely define water transparency.
