Incidence of cyanobacteria started early this summer, but towards the end of summer abundant cyanobacteria occurrences halted

Cyanobacteria started to increase in abundance early this summer, but during late summer less cyanobacteria surface blooms were observed than normally. In the Finnish southwestern open sea areas cyanobacteria were abundant throughout the summer, but  mixed in the water column, and long-lasting surface blooms did not develop. Most observations of cyanobacteria from the Baltic Sea area around Finland were done in the Archipelago Sea and coastal areas of the Gulf of Finland. In lakes, cyanobacteria were abundant only occasionally during the summer, but in August exceptionally little cyanobacteria was observed.
