Cyanobacteria are still quite abundant in the Gulf of Finland, in the Archipelago Sea and in the Bothnian Sea, but cyanobacteria are now mixed into the water and wide surface blooms have not been observed anymore in the Finnish sea areas. In lakes, observations of cyanobacterial blooms have decreased and the cyanobacterial situation is now typical for this time of the summer. New surface blooms may occur if the weather is warm and calm. More in Finnish
