Subtidal algal communities of Inchon Dock, an enclosed artificial dock in the western coast of Korea, were investigated qualitatively and quntitatively. Assessments of species composition, biomass dominant species, and vertical distribution were conducted from January to December, 1990. During the study, benthic marine algal community was disturbed completely by water blooming in June, and was recolonized from July. Forty-five species of marine algae, 18 blue green, 13 green, 6 brown, and 8 red algae, were identified as results. Mean biomass was in ranges of 53.50-118.00g-dry wt/㎡ in community before disturbance and 0.57-2.62g-dry wt/㎡ after it. Dominant species determined by biomass and frequency were Polysiphonia morrowii and Ceramium fastigiramosum before disturbance, while Lyngbya semiplena, Lyngbya lutea and Lyngbya rivulariarum after disturbance as pioneer colonizers.
