Raw swath bathymetry and acoustic backscatter data acquired near-bottom in 2021 from the frontal thrust of the Cascadia Margin with MBARI's Mapping AUV (MAUV1)

This Raw swath bathymetry data set was collected with a Reson T50-S 400 kHz multibeam sonar system on MBARI's Mapping AUV (MAUV1) on missions 20210728m1 and 20210801m1, in 2021. The data files are in Reson s7k format (compatible with MB-System as mbio format 88) and contain raw 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 Scientist - David Caress, Charles Paull; Project PI - Jenna Hill and investigators: Jannet Watt, Jenifer B. Paduan and Eve Lundsten (MBARI)). 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.
