Excessive phytoplankton concentration turns Thessaloniki sea green
The sea in the northern port city of Thessaloniki turned green on Tuesday, due to excessive concentration of phytoplankton in the area.
According to voria.gr, the environmental phenomenon of eutrophication in the Thermaic Gulf, which leads to excessive concentration of plant nutrients in aquatic ecosystems, is related to high temperatures and southerly winds that have pushed the phytoplanktons onto the city’s coastline.
