Sogo Geophysical Exploration Co., Ltd. and Tokai University carried out the high-resolution three-dimensional seismic survey in order to acquire detailed geological data of shallow-water area in October 2017. The site is off Udo hill in western Suruga Bay. We used a small boat ( 18 tons ) and very compact survey system consisting of one boomer sound source, four ultra mini-streamer cables ( 8 channels with a 2.5 m group interval ) and a digital data recorder on the boat. The picture above taken with a drone camera shows four streamer cables arranged at intervals of 8 m and a boomer in the middle of the streamer cables are towed behind the boat's afterdeck.
