We carried out a deep seismic survey using a large airgun array with total capacity of 12,000 cubic inches and a 204-channel multi-channel hydrophone streamer system (MCS) in the southern Izu-Ogasawara arc-backarc area. The survey was conducted on the R/V Kairei of the Japan Agency for Marine-Earth Science and Technology (JAMSTEC) during 5 July --27 July 2006 (KR0607 cruise). Objectives of this cruise were to obtain crustal deformation data of the southern Izu-Ogasawara arc area, which was formed in the Eocene, Miocene, and by the currently active arc. During this cruise, three MCS seismic lines were set along the Ogasawara Ridge and across the entire southern Izu-Ogasawara arc.
