Summary of algal bloom monitoring June-August 2020: Varying cyanobacterial blooms in lakes during the summer, unusual cyanobacterial observations in northern parts of the Bothnian Sea and the Kvarken

The cyanobacterial situation over the past summer has been variable both in inland waters and sea areas. The number of cyanobacterial observations during June–August followed the weather conditions qu...

Algal bloom monitoring August 20, 2020: Cyanobacterial surface accumulations in open sea areas have become less intensive, but cyanobacterial occurrences in coastal areas and lakes have increased at some sites

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. In coastal a...

Algal bloom monitoring July 23, 2020: Cyanobacteria occurrences have slightly increased in lakes, in sea areas cyanobacteria are mostly mixed in the water due to strong winds

Cyanobacteria have been observed in both sea areas and lakes. In the sea areas, cyanobacteria are mostly mixed in the water due to strong winds. In the coastal areas, cyanobacteria have been observed...

Algal bloom monitoring July 16, 2020: Cyanobacteria occurrences have increased both in lakes and sea areas

In both sea areas and lakes cyanobacteria has been observed more than during the last week. Although, when comparing this week to the previous summers’ same period of times, the cyanobacteria occurren...

Algal bloom monitoring July 9, 2020: Cyanobacteria situation is calm both in Finnish lakes and sea areas

© Ilkka Lastumäki The cyanobacteria situation has stayed moderate both in Finnish lakes and sea areas. Windy and cloudy weather have carried on to restrain the occurrences. The ...

Algal bloom monitoring July 2, 2020: Occurrence of cyanobacteria has decreased in both Finnish sea areas and in lakes

Less cyanobacteria have been observed at national algae monitoring sites as compared to last week. Windy and cloudy weather has restrained the occurrence of cyanobacteria both in the Finnish sea areas...

Algal bloom monitoring June 25, 2020: The amounts of cyanobacteria have increased in both Finnish sea areas and in lakes

This week, in both Finnish sea areas and in inland waters, greater amounts of cyanobacteria have been observed as compared to last week. The warm weather period in June has promoted the growth of cyan...

Algal bloom monitoring June 18, 2020: Increasing numbers of cyanobacteria during Midsummer week

During the Midsummer week, cyanobacteria have started to occur in increasing numbers both in lakes and in the southern and southwestern parts of Finnish sea areas. The exceptionally warm weather in Ju...

Algal bloom monitoring June 11, 2020: Cyanobacterial occurrences have slightly increased both in Finnish sea areas and in lakes

The cyanobacterial situation has not notably changed from that of last week; the number of observed cyanobacterial occurrences have merely slightly increased in southern Finland in both Baltic Sea wat...

Algal bloom monitoring June 4, 2020: Some cyanobacterial blooms in the sea areas, scarce observations of cyanobacterial blooms in lakes

The Finnish Environment Institute SYKE has started this week its cyanobacterial bloom reporting for the summer 2020. In the Finnish sea areas some cyanobacteria have been observed locally. In lakes, o...

Algal Bloom Monitoring August 22, 2019: Cyanobacterial blooms have decreased in the Finnish sea areas and lakes

Since last week, the amount of cyanobacterial blooms has decreased both in the Finnish sea areas and lakes.

Algal Bloom Monitoring, August 15 2019: Cyanobacteria situation calm both in the Finnish sea areas and in lakes

Cool and unstable weather has restrained cyanobacteria occurrence both in the Finnish Sea areas and in lakes. In the sea areas cyanobacteria can still be found in the deeper water layers, and also som...

Algal bloom monitoring August 8, 2019: Cyanobacteria occurrence still continues in the Finnish sea areas, in lakes less cyanobacteria observed than typically this time of summer

Observations reveal a large surface cyanobacteria bloom in the Baltic Proper that extends north close to Finnish coastal areas. Blooms have also been reported in the southern part of the Bothnian Sea....

Algal bloom monitoring August 1, 2019: Cool and windy weather has slowed down the growth of the cyanobacteria in Finnish sea areas and lakes

The cooler and windier weather this week has slowed down the growth of the cyanobacteria and kept them mixed in water. Cyanobacterial blooms have declined in the Baltic Sea as well as in lakes since l...
