Phytoplankton communities were investigated 13 times during the period from November, 1995 to December, 1996 in the coastal area of Kori. A total of 162 taxa (including unidentified species) were observed£» 120 diatoms, 3 silicoflagellates, 34 dinoflagellates, 2 euglenoids, 1 chlorophyte and 2 unidentified microflagellates. A diatom species, Skeletonema costatum (Greville) Clove dominated all the year round. The standing stocks of phytoplankton ranged from 94 cells/ml in August to 1059 cells/ml in July. The peaks of standing stocks occurred in February and July. The effects of thermal effluent to the phytoplankton communities changed seasonally and might affect increasing the standing stocks where about 1 ¡­ 3 km from the discharge of Kori Nuclear Power Plant in autumn and winter. But the effects of thermal effluent must be negative in summer.
