Cyanobacterial blooms increase in sea, lakes

Blue-green algae increased this week both in inland waters and in the, said the Finnish Environment Institute (SYKE) in a press release on Thursday

Blue-green algae surface blooms have been observed in many places in the open sea areas of the northern part of the Gotland Basin and in the vicinity of the western coast of Finland.

Blue-green algae has also been more commonly observed in lakes.

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.
