Abstract:
Multibeam bathymetry raw data were recorded in the Bering Sea and the North Pacific during AleutBio cruise SO293 that took place between 2022-07-24 and 2022-09-06. The data were collected using the ship's own Kongsberg EM 122 to assess marine habitats and to safely deploy gear in the survey areas. Transit data was also recorded in between. Furthermore, the results are integrated into the US Project Seascape Alaska that aims to fully map the U.S. waters off Alaska. Eight sound velocity profiles (SVP) and one SVP from the World Ocean Atlas (WOA09 DB) were applied on the data for calibration. SVP data can be found with the raw data publication. Please see environmental data (zip file) and the cruise report for details. The data were processed using QPS Qimera software v2.4.5 with manual editing in the UTM2N coordinate system (EPSG:32602). Data products include an XYZ ASCII file with accepted soundings with a minimum depth value of -255,6 m and a maximum depth value of -7287,5 m and a GeoTIFF with a resolution of 200 m for overview purposes only and not for scientific analysis or navigation.
