The researchers deployed a remotely operated vehicle to a depth of 70 meters (230 feet) off San Diego to test the ability of its camera to identify the characteristics of the seafloor, as well as the responsiveness of the ROV's grabber. The UC San Diego researchers also tested a multibeam sonar unit in preparation for field research that will support Morris' PhD work. Photo: Sean Horton
