Summer algal blooms in the Baltic Sea

It is sunny, it is warm, it is summer. The warm weather, decreasing winds and relatively high concentrations of nutrients in the Baltic Sea are ideal conditions for algal blooms. As you probably read in the newspaper, SMHI is tracking the accumulation of algal blooms at the sea surface. Currently the North of Öland is in the risk zone for large algal blooms. Please follow the homepage of SMHI for the current phytoplankton situation and risks.
