СЕЗОННЫЕ И МЕЖГОДОВЫЕ ИЗМЕНЕНИЯ ПЛАНКТОННОГО СООБЩЕСТВА В СВ ЧАСТИ ЧЁРНОГО МОРЯ: РОЛЬ БИОТИЧЕСКИХ И АБИОТИЧЕСКИХ ФАКТОРОВ

We evaluate the state of pelagic ecosystem at the NE shelf of the Black Sea in 2005–14. Seasonal and interannual changes of the sea temperature, concentration of Chl-a, nutrients, biomass and composition of phyto- and zooplankton were analyzed. A tendency to reduce biomass and changes in composition of phyto- and zooplankton were observed which might be connected with the direct and indirect impact of the sea surface temperature rise.
