The long-term seasonal changes in chlorophyll concentration, primary phytoplankton production and water temperature in the shelf zone of the northwestern part of the Black Sea from 1998 to 2015 were studied. Data from SeaWiFS satellites from 1998 to 2008 and MODIS from 2008 to 2015, obtained for the surface layer of the sea, were used for the analysis. The concentration of chlorophyll a and the primary production of phytoplankton were calculated using previously developed models for the Black Sea phytoplankton. The trends of the studied indicators were determined by the least squares method. In the Danube region, a positive trend (at the significance level p < 0.1) of average annual values of chlorophyll concentration was revealed in the absence of a statistically significant trend in primary production. In the remaining waters of the northern and western coasts, there were no pronounced trends in the concentration of chlorophyll and primary products. In the area exposed to the Danube River runoff, the average phytoplankton production over 18 years was the highest compared to other areas and was (87.05±25.75 mgC∙m–3∙day–1). Positive temperature trends were observed in most of the coastal area of the Black Sea and the area of the depth dump in the western part of the sea (at the significance level p < 0.1). The conducted studies have shown the absence of noticeable changes in the development of phytoplankton due to global warming. © 2022 Space Research Institute of the Russian Academy of Sciences.
