Marine Geoscience Data System
Arctic_MBARI Bathymetry
Processed bathymetry data (GeoTIFF images) 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 Konsberg EM2045 Multibeam sonar system in 2019. The file is in GeoTIFF image format, is un-projected in geographic coordinates, 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.
