Processed swath bathymetry and acoustic backscatter data acquired near-bottom in 2021 from 41.72° N along the frontal thrust of the Cascadia Margin with MBARI's Mapping AUV (MAUV2)

This Processed swath bathymetry data set was collected with a Reson T50-S 400 kHz multibeam sonar system on MBARI's Mapping AUV (MAUV2) mission 20210801m2 collected in 2021. The data files are in MB-System-compatible format (mbio format 89) and contain processed swath bathymetry and acoustic backscatter data. The AUV survey mission was conducted during the 2021 cruise on R/V Rachel Carson along the Cascadia Margin. Cruise Chief Scientists - David Caress, Charles Paull; PI - Jenna Hill; and, investigators: Jenifer B. Paduan, Eve Lundsten and Janet Watt. Data were acquired as part of a collaborative research project between MBARI and the U.S. Geological Survey. Funding for the AUV mapping was provided from the David and Lucile Packard Foundation.
