The Cyanobacterial surface accumulations in open sea areas have become less intensive this week, but cyanobacterial occurrences in coastal areas and lakes have increased at some sites, said the Finnish Environment Institute (SYKE) in a press release on Thursday.

Cyanobacterial surface accumulations in open sea areas of the Gulf of Finland and the Bothnian Sea are still visible in satellite images, even though they are less intensive than earlier.

Meanwhile, in coastal and archipelago areas, the observations of cyanobacteria are more abundant than average for the season.

In lakes, warm weather has increased cyanobacteria at some sites, but the observations of cyanobacteria are in most regions still fewer than average for the season.
