Marmara Sea covered with mucilage

Show mucilage covers surface of the Marmara Sea, coast of Istanbul, Turkey on June 7, 2021.The Ministry of Environment and Urbanization announced that the largest sea cleaning campaign will be launched to eliminate mucilage(sea snot) . Mucilage, which was observed intensively on the water in the Sea of Marmara in 2007, is due to the excessive increase in the sea of single-celled plant microorganisms called "phytoplankton". In the Marmara Sea these single-celled microorganisms also multiply by taking advantage of the marine pollution caused by domestic and factory wastes and the changing water temperature level due to global climate change.
