Raw sidescan and sub-bottom data acquired near-bottom along the frontal thrust of the Cascadia Margin with MBARI's Mapping AUV (MAUV1)

This raw sidescan and sub-bottom data set was collected with an Edgetech 2205 sonar/sub-bottom system on MBARI's Mapping AUV (MAUV1) on missions 20210728m1, 20210730m1, 20210801m1, 20210815m1, and 20230817m1. 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 except for the three missions 20210728m1, 20210730m1 and 20210801m1 for which real-time navigation was embedded in the files as a temporary experiment. The AUV survey missions were conducted during R/V Rachel Carson cruises along the Cascadia Margin. 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.
