Description
Summary:Bathymetry data was acquired during R/V MARIA S. MERIAN cruise MSM57-1 off Svalbard between 29.07.2016 and 12.08.2016. The cruise investigated gas hydrate systems and their dynamics at the continental margin of Svalbard. The key instrument to be used during this expedition was the Bremen deep sea drill rig MeBo. Investigations during leg 1 were concentrated mostly at the Vestnesa Ridge. CI Citation: Paul Wintersteller (seafloor-imaging@marum.de) as responsible party for bathymetry raw data ingest creation of products and approval.Description of data source:During the MSM57/1 cruise, the hull-mounted Kongsberg EM122 multibeam echosounder (MBES) was utilized to perform bathymetric mapping in middle to deep water depths. Two linear transducer arrays in a Mills Cross configuration transmit acoustic signals of a nominal sonar frequency of 12 kHz. With 432 soundings per swath, the emission cone has a dimension of max 150° across track and 2° along track. With a reception obtained from 288 beams, the actual beam ...
