Multivariate analyses has been performed on both qualitative and quantitative data of phytoplankton samples collected off the coast of Kunsan in October, 1980, and in March, 1981. The result shows that structure of the phytoplankton cmmunity largely depended on hydrological conditions. Thus the study area can be divided into three phyto-hydrographic zones; the waters under influence of the proper water of the Yellow Sea, the waters where mixing with fresh water occurred, the waters from the south. Biomass was estimated of plasma volume and cell carbon content. The mean value of cell carbon was 30.0$\mu\textrm{g}$/$\ell$ in October and 26.6$\mu\textrm{g}$/$\ell$ in March. Relatively low value of biomass seems to be related to great turbidity of the area. Microflagellates of about 5$\mu\textrm{m}$ were abundant with a density of million cells per liter. Their abundance showed on considerable seasonal variation.
