The capabilities and limitations of using satellite remote sensing data to detect areas of intense algae bloom are investigated. The study region was the Rybinsk Reservoir, the satellite data were obtained by Landsat, Envisat ASAR and MERIS, and ERS-2 SAR. We conclude that the Landsat data are best suited for the detection of cyanobacteria blooms, while SAR data better reveal areas of intense diatom bloom. From Envisat MERIS data, chlorophyll-a concentration and total suspended matter maps were compiled to estimate the algae biomass It is shown, that in cases of intense cyanobacteria bloom, when algae form dense clumps on the water surface, standard algorithms developed by NASA for Envisat MERIS data have important limitations. Satellite data analysis results were compared with ship measurement data obtained in June and August months of 2010 and 2013. A good qualitative agreement was demonstrated. The biogenic pollution state of the Rybinsk Reservoir was compared to that of the Baltic Sea.
Keywords: harmful algae bloom, cyanobacteria, diatoms, satellite observations, radar remote sensing, the Rybinsk Reservoir, the Baltic Sea, Landsat, Envisat
