MBARI mapping AUV operations in the gulf of California 2015

摘要

The Monterey Bay Aquarium Research Institute (MBARI) has conducted high-resolution multibeam bathymetry, sidescan, and subbottom sonar surveys in the Gulf of California and offshore northern Baja California using an autonomous underwater vehicle (AUV) as part of a four-month, two-ship oceanographic expedition, Fig 4. The seafloor mapping AUV D. Allan B was operated from R/V Rachel Carson, achieving 21 successful surveys during February and March 2015, operating to a maximum depth of 3800m. The 1-meter lateral resolution bathymetry maps and subbottom profiles were used to guide subsequent ROV Doc Ricketts dives made from MBARI's R/V Western Flyer, which combined visual surveys, sampling, and in situ experimentation by several different science groups.
