Abstract:
Multibeam bathymetry 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.
During data acquisition, sound velocity measurements using sound velocity profiles (SVP) from sound velocity probes was applied on the data for data calibration. Ancillary SVP raw data (.asvp files) and SVP from CTD-cast (.txt) are part of this dataset publication.
Data are unprocessed and therefore may contain incorrect depth measurements without further processing. Data can be processed e.g. with the open source software package MB-System (Caress, D. W., and D. N. Chayes, MB-System: Mapping the Seafloor, http://www.mbari.org/products/research-software/mb-system/, 2017).
During data acquisition the Acoustic Doppler Current Profiler (38 and 75 kHz) was occasionally switch on. When switched on, the centre of the beam showed erroneous measurements within regular intervals. However, this did not significantly lead to data quality loss in general. East of the survey area, data were recording during simultaneous operation of the Atlas Parasound P70 system. This led to complete false measurement data. However, these data are also part of this publication and marked in the parameter table.
