Multibeam bathymetry raw data (Kongsberg EM 122 entire dataset) of RV MARIA S. MERIAN during cruise MSM97/2

Multibeam bathymetry 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 moni...

Description
Summary:Multibeam bathymetry 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. 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 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).
