Extensive algal blooms, specifically cyanobacteria, are currently visible in the northern and central Baltic Sea. These blooms have been detected in areas surrounding Gotland and north of Öland. Cyanobacteria can be harmful to aquatic life and potentially human health. The extent of the blooms suggests potentially significant ecological impacts. Authorities are likely monitoring the situation to assess the blooms’ spread and severity. This phenomenon is a recurring issue in the Baltic Sea, often linked to nutrient runoff and warmer water temperatures. Further investigation is needed to determine the long-term consequences of these blooms.
