Swath sonar bathymetry data used for that dataset was recorded during RV MARIA S. MERIAN cruise MSM05/3 using Kongsberg EM1002 multibeam echosounder . The cruise took place between 15.06.2007 and 04.07.2007 in the northwestern Barents Sea. The cruise aimed to investigate the interrelation between hydrosphere, geosphere and climate in the western Greenland coastal waters and the impact to environmental change during the Late Quaternary. For the identification of sedimentary basins the multibeam echosounder and the new parametric echosounder PARASOUND DS3 were used. In addition, multibeam bathymetric data acquisition has been deployed for the interpretation of the origin of various seabed features.

Description of processed data sources: During the MSM5/3 cruise, the moon-pool mounted KONGSBERG EM1002 multibeam echosounder (MBES) was utilized to perform bathymetric mapping in shallow water depths. 111 beams are formed for each ping while the seafloor is detected using amplitude and phase information for each beam sounding.

Responsible person during this cruise / PI: not stated. Description of data processing: Postprocessing and products were conducted by the Seafloor-Imaging & Mapping group of MARUM/FB5, responsible person Paul Wintersteller ([e-mail]). The open source software MB-System (Caress, D. W., and D. N. Chayes, MB-System: Mapping the Seafloor, https://www.mbari.org/products/research-software/mb-system, 2017) was utilized for this purpose. Tide and a sound velocity profile were applied to the MSM5/3 data; there were no corrections for roll, pitch and heave applied. Using Mbeditviz, artefacts were cleaned manually. NetCDF (GMT) grids of the edited data as well as statistics were ...
