Toxic blue-green algae have been detected across large parts of the Baltic Sea. The occurrence is normal for the season according to SMHI.
Satellite images show extensive algal blooms in the northern and central Baltic Sea. The cyanobacteria are visible around Gotland and north of Öland.
Jörgen Öberg, oceanographer at SMHI, says the first signs appeared two weeks ago. The occurrence has increased gradually since then.
The algae are expected to remain at similar levels in the coming days due to weak winds. Warmer weather may affect the development.
