Cyanobacterial blooms increase in sea, lakes

The amounts of cyanobacteria have increased in both Finnish sea areas and in lakes this week, said a press release issued by the Finnish Environment Institute (SYKE).

The warm weather period in June has promoted the growth of cyanobacteria, as is typical of heatwaves.

With the continuing warm weather, the number of surface accumulations may still increase in the next few days.

Although the amount of cyanobacterial observations has increased, the observations made in the Finnish sea areas are mainly of sparse amounts of algae, and in most of the inland sites which are part of the regular national lake observation network, no cyanobacteria were observed.
