Dynamics of the Phytoplankton Community in the Coastal Waters of Chuksan Harbor, East Sea

In order to investigate the distribution of phytoplankton community in the coastal waters of the Chuksan Harbor, East Sea, the abundance and biomass of phytoplankton have been evaluated through seasonal interval sampling from April 2000 to October 2002. A total of 363 different phytoplankton species was observed and most of them were composed of diatoms. The mean abundance and chlorophyll-a concentration of phytoplankton during the study period ranged from 56 x 10 super(3) to 720 x 10 super(3) cells L super(-1) and from 0.78 to 3.29 mu g chl-a L super(-1), respectively. The relative contribution of the size-fractionated phytoplankton to phytoplankton community showed difference according to seasons. The average contribution of nano-phytoplankton(
