Photo & Video Log
This page contains photos and videos related to the Northeast Lau Response Cruise 2009 exploration, that took place from this May 5 to 13. Video and images were obtained by cameras mounted on the Jason II ROV remotely operated vehicle (ROV). The scientific party and Jason team were onboard the University of Washington research vessel R/V Thomas G. Thompson. The sound on the video clips was recorded separately by a hydrophone (underwater microphone) placed on the sea floor about 15 meters (50 feet) away and later synchronized to the video. The location of the summit of the West Mata volcano is 15° 05.68’S; 173° 44.95’W. Click on any image to view a larger version and for additional information.
