Processed bathymetry data (ESRI ASCII grids) acquired with a ship-mounted sonar system in 2019 on the continental slope of the Canadian Beaufort Sea

This high-resolution gridded bathymetry data set was acquired with a ship-mounted Kongsberg EM2045 Multibeam sonar system in 2019. The file is in ESRI ASCII grid format, is projected in UTM coordinates (Zone 8N), and was processed using the open-source MB-System multibeam sonar processing software. The grid has 4-meter horizontal resolution.The survey mission was conducted during CCGS Sir Wilfrid Laurier IOS cruise 2019-090 in the Beaufort Sea (Cruise Chief Scientist - Humfrey Melling, Department of Fisheries and Oceans Canada; project PI - Scott Youngblut, Canadian Hydrographic Service). Data were acquired as part of a collaborative research project between MBARI, the Geological Survey of Canada, and Department of Fisheries and Oceans Canada.
