dc.description.abstract Dokdo (do means a island), our study area, is a volcanic island, which is located in the northeastern part of the Ulleung Back-Arc Basin, the East Sea and approximately 216.8 km away from the eastern part of the Korean peninsula. The Dokdo volcano anomalously emerges, rising abruptly from the sea floor (?2,100 m below sea level). Dokdo comprises two main islets (Seo-do and Dong-do) and the associated submerged volcanic edifice. To management the eco-system of coastal area and establish the policy against the change of marine environment, advanced nations for marine have conducted benthic habitat mapping studies like PIBHMC (Pacific Islands Benthic Habitat MappingCenter) and MESH (Mapping European Seabed Habitats) projects. For the benthic habitat mapping of the southern coastal area of Seo-do, the precise topographical map of the coastal area was made using the detailed bathymetry data from multi-beam echosounder (EM 3001, Kongsberg). The seafloor images of the survey area were obtained by Side Scan Sonar (4125, Edgetech). The grain size and TOC (Total Organic Carbon) of 6 surface sediment samples of the survey area were analyzed. We used small research vessels for this study, because of shallow water. The bathymetry data of the survey area show that the range of water depth is about from 1 m to 28 m and the underwater reefs are irregularly scattered and extended from inland of Seo-do, with shallow water depth (witvolcano anomalously emerges, rising abruptly from the sea floor (?2,100 m below sea level).
