A marine seismic exploration with 3.5khz sub-bottom profiler was carried out as a part of preliminary geological survey in the Buckhang area, Pusan, where an ocean bridge is considered to be constructed connecting Chunghak-dong, Yongdo-ku with Kamman-dong, Nam-ku. The seismic survey was conducted on the 10 survey lines(total length of 10km), and the aim of this survey was to profile depth of bedrock and investigate subsurface structures such as faults and fracture zones that might be present in the area. The subsurface structure consists of the upper sediment layer and the lower acoustic bedrock. The thin sediment layer covers the bedrock on the west and is getting thicker eastward. The bedrock depth also increases eastward, up to 15m at the west area and 24m in the east area. A minor fault is known to exist at the shore of Chunghak-dong, Youngdo-ku, but there is no evidence that indicates the existence of fault or fracture zones over the study area.
