Description: Water column raw data using the ship's own Kongsberg EM 712 multibeam echosounder was not continuously recorded during RV MARIA S. MERIAN cruise MSM97/2. Data were recorded on 5 days between 2020-12-12 and 2020-12-22 in the North Sea and acquisition almost continuously monitored during the survey. The approximate average depth of the entire dataset is around 37m. 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.928539. 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.
