Multibeam data were collected with RV Maria S. Merian along the route of cruise MSM108. Multibeam sonar system was Kongsberg EM122. SVPs were retrieved from CTD data and synthetic profiles from World Ocean Atlas 18. SVPs were processed with HydrOffice SoundSpeedManager (https://www.hydroffice.org/soundspeed/main) and extended with World Ocean Atlas 18 (https://www.ncei.noaa.gov/archive/accession/NCEI-WOA18). SVP data were applied during acquisition. Multibeam data are unprocessed and may contain outliers and blunders and should not be used for grid calculations and charting projects without further editing. The raw multibeam sonar data in Kongsberg multibeam processing format (.all) were recorded with Kongsberg SIS. Raw data files can be processed using software packages like CARIS HIPS/SIPS or MB-System. For updated vessel configuration file check further details.

These data should not be used for navigational purposes.
