Literature available on the subject and original data obtained by the authors have been used. Quantitative development and taxonomic composition of phytoplankton are described along with changes found in the vertical profiles and along the transects. In recent years abundance of phytoplankton has been reported to increase all over the Black Sea. Phytoplankton blooms usually appeared owing to diatoms (Nitzschia delicatula, Cerataulina bergonil, Chaetoceros socialis a.al.) and Chrysophyta (Emiliania huxleyi), Phytoplankton becomes more and more abundant whether it is in a coastal area or at the open sea. The trends and prospects of further research are outlined, taking into account the enhancing anthropogenic impact upon coastal and deep-sea areas. The authors offer to add to the list of traditional topics problems related to algae blooms that change correlations between auto- and heterotrophic complexes of nanno- and microphytoplankton. It is suggested to unify diverse sampling, treatement and processing techniques applied by phytoplanktologists from different countries in order to reach the conformity of results.Приведены результаты многолетних исследований состава и количественного развития фитопланктона: предложены перспективные направления дальнейших исследований структуры черноморского фитопланктона.ru
