Chile Triple Junction 2012: NE Lau Basin on Scripps Research Vessel Roger Revelle between 20120909 and 20120926

Description

The Submarine Ring of Fire 2012 cruise will use the University of Bremen Quest 4000 remotely operated vehicle to locate, map and sample hydrothermal sites at seamounts and spreading centers in the Lau Basin. The sites were discovered by water column surveys, camera tows and prior dives with a remotely operated vehicle during cruises funded by NOAA, NSF and Nautilus Minerals Inc. in the past 8 years. They range in depth from ~750 to ~2600 m. We expect to visit 10 to 13 sites during the cruise. When the ROV is not in the water we will conduct other operations including multibeam surveys (with concurrent towed magnetometer, gravimeter, ADCP, and HDSS), CTD vertical and towed hydrocasts generally at locations close to the planned targets.
