The species composition and distributional patterns of marine benthic algae in the coastal waters off Soo Island, Jinhae were investigated seasonally throughout 2018. A total of 87 species, 7 Chlorophyta 15 Phaeophyta, and 65 Rhodophyta were recorded, and dominant species were Ulva australia, Codium fragile, Sargassum horneri, S. micracanthum, Amphiroa beauvoisii, A. foliacea, Caulacanthus ustulatus, Ceramium sp., Chondracanthus intermedius, C. tenellus, Gelidium elegans, G. vagum, Lithophyllum okamurae, Lomentaria catenata, and Polysiphonia sp. during study periods. Especially the vertical distribution of dominant algal species was remarkable: U. australia, and C. fragile were dominated in the upper part, S. thunbergii, and C. tenellus were in the middle part, and S. micracanthum, S. horneri, A. beauvoisii, and L. catenata mainly occurred in the low part of tidal zone. The numbers of species were different with seasons and stations; Higher number of species was 56 species in winter, whereas 40 species were the lowest in summer. The number of algal species was higher at stations 5 and 6 while the lower value was at stations 1 and 2 than other stations. The spatial distribution of marine benthic algal composition in MDS ordination was due to differences in the local microhabitats for marine algal species and physical characteristics such as current and water movement.
