Spatial and temporal variability of the phytoplankton biomass and its stocks in the different parts of the Black Sea were analyzed from 1948 to 2001 period based on the statistical treatment of multi-year investigations. Mean phytoplankton biomass in the southern and central parts of the sea varies between 10 - 20 g·m-2, gradually increasing to 30 - 40 g·m-2 on the north-west shelf and reaching 50 g·m-2 and more in the Danube region. In the deep area seasonal variability of the phytoplankton biomass is characterized by two close to the U-shaped types. In the shelf zone of the western and northwestern parts of the sea seasonal variation is described by three basic types, and in the highly dynamic slope water their number increases to five ones at least. Long-term dynamics of phytoplankton is characterized by undulating changes in its development in the absence of statistically significant trends for the series of annual anomalies of the biomass. In the deep part of the sea it’s closely related to the winter climate conditions and to the interannual variability of river runoff in the Danube region. The total biomass of the Black Sea phytoplankton amounted to 7.9·106 tons of wet weight on average for the year during the study period.
