Water Quality and Phytoplankton in the Waters of Manripo and Daechon Beaches

In spite of high concentrations of SS(>30mg/l) in July 2010, the water condition of Manripo was fine for swimming as COD data lower than 2.0mg/l in summer continuously. The bloom of phytoplankton or red tide were not occurred in the waters. COD data from the waters of Daechon were lower than 2.0mg/l, except August. Relatively high SS concentrations were the characteristics of Daechon beach and were caused by the effects of mud resuspension. The dominant taxa of phytoplnkton communities were consist of diatoms as the normal groups of neritic sea waters.
