JAMSTEC SeaBeam

The original data were collected from the two cruises to Hawaii with a SeaBeam 2112 multibeam seafloor mapping sonar system during a collaborative research program between scientists from Japan and U.S. institutions that was funded by the Japan Marine Science and Technology Center (JAMSTEC) in 1998 and 1999. Because identical SeaBeam 2112 sonar mapping systems are mounted on duplicate hulls of the sister ships Kairei and Yokosuka, merging their data is relatively simple and seamless. Approximately 115,000-km² was surveyed in the southeastern Hawaiian Islands.
