This study was to clarify the variations in a marine ecosystem through examining the species composition of phytoplankton in the coastal water of Baegyado Island during winter. Water temperature, salinity, SS, NH-N, NO-N, NO-N and SiO-Si were significantly different and in inverse proportion to the chlorophyll a and species number according to stations and water depth. The total number of species was 88, composed of 94% Bacillariophyceae, 3.4% Chrysophyceae, 2.2% Dinophyceae and 1.1% Euglenophyceae. The dominant species were Rhizosolenia setigera, Skeletonema costatum and Stephanopyxis palmeriana. The maximum of standing crops was 5,450cells·ml^(-1), while the minimum was 1,700cells·ml^(-1). The coastal water was influenced with two water bodies which had characteristics of low water temperature - low salinity and high water temperature - high salinity.
Key words: Baegyado Island; marine environment; species composition; standing crop; winter
