To acquire underground and submarine information about a possibility of submarine groundwater discharge (SGD) resources, we conducted dipole-dipole array submarine electrical resistivity surveys and high resolution seismic survey in the east maritime regions of Busan city. Anomalies of low resistivity and reflective surfaces of fracture were observed at the same location. These results show that resistivity anomaly suggests effective groundwater discharge paths. From the analysis of resistivity-depth profiles, the seven areas were selected for the potential points of SGD. The low resistivity distributions appearing in depths from 40 to 100 m indicate the location of Aquifer. Low resistivity anomalies are classified into vertical (V-type) and cylindrical (C-type) anomalies. Due to the effect of seawater intrusion, cap layer boundary of cylindrical anomaly is not clear.
