This high-resolution gridded bathymetry data set was acquired with a Reson SeaBat 7125 Multibeam sonar system in 2013 and 2016 on MBARI Mapping AUV missions 20131003m1, 20160927m1, 20160927m2, 20160928m1, 20160929m1, 20160929m2, 20161001m1, and 20161001m2. The files are in GMT-compatible netCDF format, are un-projected in geographic coordinates, and were processed using the open-source MB-System multibeam sonar processing software. The grid has 1-meter horizontal resolution. The AUV survey missions were conducted during CCGS Sir Wilfrid Laurier IOS cruises 2013-22 and 2016-13 in the Beaufort Sea (Cruise Chief Scientist - Humfrey Melling, Department of Fisheries and Oceans Canada; project PI - Charlie Paull and investigators: Dr. David Caress and Eve Lundsten, MBARI). Data were acquired as part of a collaborative research project between MBARI, the Geological Survey of Canada, and Department of Fisheries and Oceans Canada. Funding for the AUV mapping was provided from the David and Lucile Packard Foundation.
