Strong winds have dispersed blue-green algae surface blooms in inland waters and at sea, said Finnish Environment Institute (SYKE) in a press release on Thursday.

The blue-green algae situation in lakes is calm considering the time period. Even in sea areas, blue-green algae have only been detected in subsurface layers in the eastern Gulf of Finland.

SYKE observes the cyanobacteria occurrence as part of the monitoring of the state of the environment in Finland.

The national cyanobacterial monitoring is carried out as part of the monitoring of the state of the environment in cooperation with the Centres for Economic Development, Transport and the Environment, municipal environmental and health authorities, and the SYKE. Finnish Rotary Clubs are also actively involved in nationwide cyanobacterial monitoring.

The cyanobacterial monitoring is based on the monitoring of cyanobacterial deposits in surface water. The intention is to provide an overview of the cyanobacterial situation in different water bodies.

The monitoring includes about 400 permanent observation sites across the country on inland and coastal waters and in the archipelago.
