Changes in the state of phytoplankton coenoses and water pollution of the Novorossiysk port area
The composition of phytoplankton of seven stations in the port area of Novorossiysk during threemonth (August, September, November) vegetation period was characterized by the prevalence of diatoms (Diatomeae) microalgae both in the abundance and biomass. The peak of the total abundance (79.9 thousand cells/l in the port area and 245 thousand cells/l in the middle part of the bay) and biomass (the average value 91.4 mg/m3 in the port area and 219 mg/m3 outside the port area) was recorded in September. Background monitoring station was characterized by a more uniform composition of the phytoplankton groups. The number of species in the port area varied in the range from 3 to 5, outside the port area — from 2 to 3. However, they comprised the species, characteristic of clean waters. The highest values of the water pollution index, which characterize the water stations as polluted and very polluted, were recorded in September. In November, the waters of five stations were estimated as clean (WPI less than 0.75), the rest — as moderately polluted (WPI within the range of 0.84–0.88).
