Intertidal algal communities of Muchangpo and Maryangri in western coast of Korea were investigated qualitatively and quantitatively. Seasonal assessments of species composition, biomass, dominant species in biomass and vertical distributional pattern were conducted from July 1986 to April 1988. Ninety-nine species of marine algae (13 Cyanophyta, 12 Chlorophyta, 24 Phaeophyta and 50 Rhodophyta) were observed, of which 90 (13 Cyanophyta, 11 Chlorophyta, 23 Phaeophyta and 43 Rhodophyta) were from Muchangpo and 83 (10 Cyanophyta, 11 Chlorophyta, 21 Phaeophyta and 41 Rhodophyta) were from Maryangri, respectively. Ordination by detrended correspondence analysis based on the floristic data from nine localities indicated that, on the whole, marine algal distribution in western coast of Korea might be divided into two regions, i.e. the north and the south, being separated at the Taean Peninsula, the mid-western coast. Seasonal fluctuations of mean biomass were 44.55-201.19g-dry wt/㎡ at Muchangpo and 19.59-134.76g-dry wt/㎡ at Maryangri. Important species determined by the specific proportion of biomass were Sargassum thunbergii, Pelvetia siliquosa and Corallina pilulifera at Muchangpo, and Sargassum thunbergii and Corallina pilulifera at Maryangri.

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.

The species composition and biomass of intertidal benthic algae at 12 widely dispersed stations representative of mid-western coast of Korea were studied. A total of 151 species of marine algae including 19 Cyanophyta, 20 Chlorophyta, 32 Phaeophyta and 80 Rhodophyta is listed. Three species were found at all 12 stations: Sargassum thunbergii, Stylonema alsidii and Gracilaria verrucosa. Biomass per unit area exhibited a wide range of variatoin, ranging from a low of 41 g dry wt·m^-2 at both Paeksajang and Taechon to a high of 549 g dry wt·m^-2 at Uihangri, the northernmost station of the study area. The latter value is higher than those reported from any other stations in western coast of Korea. Biomass was composed largely of Phaeophyta at nearly every station. Sargassum thunbergii was dominant over the study area. The distribution of corallina spp., however, is disjunct, since those occur as dominant species in biomass at the northern stations and to a lesser extent at the southern stations, but are nearly absent from the middle part of the study area.

Seasonal changes of species composition and biomass of marine algae were investigated during May 1986-February 1987, at the intertidal zone of Yonggwang nuclear power plant site and adjacent site, western coast of Korea. Total of sixty-eight species of marine algae, ten blue-green, nine green, thirteen brown and thirty-six red algae, were identified in the study. It showed rather poor marine algal vegetation in Yonggwang areas than adjacent site, Wolgok, as well as previous investigation during 1979-1980. Seasonal fluctuation of mean biomass were in the ranges of 12.67-103.66 g·dry wt/㎡ at Yonggwang areas. The dominant species in biomass were Sargassum thunbergii, Corallina pilulifera, Gelidium divaricatum and Enteromorpha compressa throughout the year.
