Raw sidescan and sub-bottom data acquired near-bottom in 2021 from the frontal thrust of the Cascadia Margin with MBARI's Mapping AUV (MAUV2)

This raw sidescan and sub-bottom data set was collected with an Edgetech 2205 sonar/sub-bottom system on MBARI's Mapping AUV (MAUV2) mission 20210801m2 collected in 2021. The data files are in JSF format (compatible with MB-System as mbio format 132) and contain raw sidescan and sub-bottom data that has not been merged with navigation. 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.
