Abstract:
Multibeam bathymetry raw data were recorded in the Atlantic during cruise MSM94 that took place between 2020-08-02 and 2020-09-06. The data were collected using the ship's own Kongsberg EM 122. Sound velocity profiles (SVP) were applied on the data for calibration. 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 UTM28N coordinate system (EPSG:32628). Data products include an XYZ ASCII file with accepted soundings with a minimum depth value of -237,1 m and a maximum depth value of -4846,4 m and a GeoTIFF with a resolution of 200 m for overview purposes only and not for scientific analysis or navigation. The resolution was chosen according to the median depth of the cleaned soundings (-2896 m) and the depth-variable resolution goal of the Nippon Foundation GEBCO Seabed 2030 Project (Mayer et al. 2018; doi:10.3390/geosciences8020063).
