Summary of algal bloom monitoring 2018: Sweltering summer brought exceptional cyanobacterial surface blooms to sea areas, in lakes abundant cyanobacterial blooms took place earlier

In the Gulf of Finland, cyanobacterial blooms during the summer of 2018 were strongest for the 2010's. Surface blooms covered at worst almost the entire Gulf of Finland. Also in the southern parts of Archipelago Sea and Sea of Åland cyanobacterial surface blooms were abundant. In lakes cyanobacteria became abundant already in late June due to warm weather and cyanobacteria were observed in lakes more than typically until the beginning of August. More in Finnish
