A Characteristics on the Distribution of Phytoplankton Community in the Sudo strait, Southern Parts of West Sea of Korea in Spring 2005

We carried out a study on the distribution of phytoplankton community, such as species composition, dominant species, standing crops and chlorophyll a in the Sudo Strait where located the southern parts of West Sea of Korea(Yellow Sea) in spring 2005. The phytoplankton community in the surface waters was a total of 64 species belonging to 38 genera. Standing crops of phytoplankton fluctuated between 14.0 x 103 cells/L and 48.5 x 103 cells/L. Dominant species were one species of centric diatom, Paralia sulcata with dominance 77.7%. Chlorophyll a concentration fluctuated between 1.95 ㎍/L and 5.17 ㎍/L in neap tide (3.58 ± 0.87㎍/L, Mean ±SD), 1.61 ㎍/L and 4.22 ㎍/L in spring tide (3.18 ± 0.60 ㎍/L). The distribution of phytoplankton community and biomass in the Sudo Strait of southern part of West Sea of Korea was controlled by the high concentration of seston weight and tidal currents.
