Sounding of the sea floor around the Ongul Islands was conducted. 410 depth data were newly obtained in the sea area from south to west of West Ongul Island. North-south trending topographic features dominate in the area west of West Ongul Island. On the other hand, the Minami-no-seto Strait between West Ongul and North Teoya Islands is composed of three small oval-shaped depressions trending east-west. The submarine landforms newly revealed in this study are generally continuous to the formerly revealed topographies. A bathymetric chart and two kinds of topographic images based on a set of DEM data around the Ongul Islands are presented.
