As typical in early summer, the number of blue-green algae observations in Finnish seas and inland water is moderate, said Finnish Environment Institute (SYKE) in a press release on Thursday.
Some blue-green algae have been observed in inland waters, mainly in Southern Finland.
In coastal areas, even slightly less blue-green algae have been detected than typical this time of year.
So far, no significant deposits of algae have been observed in offshore areas.
The blue-green algae situation in inland waters is calm, as typical in early summer.
Abundant blue-green algae have been observed at two inland water observation sites of the national blue-green algae monitoring.
Some blue-green algae have been observed at 15 inland water observation sites.
During the past week, blue-green algae observations have mostly been made in Southern Finland, but also in Central Finland and a single observation in southern Lapland. National blue-green algae monitoring has 246 active inland water observation sites.
In coastal areas, blue-green algae observations are slightly fewer than is typical in early summer. No abundant algae have been observed at the coastal observation sites of the national blue-green algae monitoring, during the past week.
Some blue-green algae have been observed at two coastal observation sites. National blue-green algae monitoring has 69 active marine area observation sites.
In offshore areas, the situation is normal for the time period. This week, unstable weather has prevented comprehensive satellite observations in the northern Baltic Sea.
Small amounts of blue-green algae mixed with water have been observed in the Gulf of Finland. No blue-green algae have been observed in the Bothnian Sea, the Archipelago Sea and the Åland Sea.
At this time of summer, pollen from coniferous trees may also occur in the water, and it may resemble blue-green algae.
In addition to official monitoring, valuable information on the blue-green algae situation is also gathered from the public. A total of 38 observations made by citizens were obtained.
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.
Information on the cyanobacterial situation in the open sea areas is mainly obtained from satellite images, but also from the Finnish Border Guard, the marine research vessel Aranda, the optical device located at the Utö Atmospheric and Marine Research Station, as well as cruise and merchant ships (MS Finnmaid and MS Silja Serenade).
The drift forecasts for cyanobacterial rafts in open sea areas are prepared in cooperation with the Finnish Meteorological Institute's Maritime Services.
SYKE reports on the national cyanobacterial situation on a weekly basis every Thursday from 19 June to 7 August 2024. The weekly algal reporting was launched in 1998.
