Water column raw data using the ship's own Kongsberg EM 122 multibeam echosounder was not continuously recorded during RV MARIA S. MERIAN cruise MSM97/2. Data were recorded on 3 days between 2020-12-16 and 2020-12-19 in the Norwegian Sea and data acquisition was almost continuously monitored during the survey. Previous to the survey, gaps in already existing database were identified using the General Bathymetric Chart of the Oceans (GEBCO 2020) Type Identifier (TID) grid. These gaps were used as a base to determine the course of the ship during the cruise. The approximate average depth of the entire dataset is around 3300m.During data acquisition, sound velocity measurements using sound velocity profiles (SVP) derived from CTD casts was applied on the data for data calibration. Ancillary SVP raw data (.asvp files) and SVP from CTD-cast (.txt) are not part of this dataset publication, but part of the corresponding multibeam raw dataset https://doi.org/10.1594/PANGAEA.927786. During data acquisition the Acoustic Doppler Current Profiler (38 and 75 kHz) was occasionally switch on simultaneously. Data are unprocessed and therefore may contain incorrect measurements without further processing. : These data should not be used for navigational purposes
