Processed bathymetry data (netCDF grids) acquired near-bottom using MBARI's Mapping AUV (MAUV1 and MAUV2) in 2021 from 41.72° N along the frontal thrust of the Cascadia Margin

This high-resolution gridded bathymetry data set was acquired with a Reson T50-S 400 kHz Multibeam sonar system in 2021 on MBARI's Mapping AUV (MAUV1) on missions 20210728m1, 20210801m1, and MBARI's Mapping AUV (MAUV2) on mission 20210801m2. The file is in GMT-compatible netCDF format, is projected in UTM coordinates (Zone 10N), and was processed using the open-source multibeam sonar processing software MB-System. The grid has 1-meter horizontal resolution. The AUV survey missions were conducted during the 2021 R/V Rachel Carson cruise 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.
