Description:
Multibeam echosounder (MBES) data recorded during RV MARIA S. MERIAN cruise MSM34-2 between 27.12.2013 and 18.01.2014 in the Black Sea. The main objective of this cruise was the mapping and imaging of the gas hydrate distribution and gas accumulations as well as possible gas migration pathways. Another objective of cruise therefore was locating and characterizing suitable gas hydrate deposits on the Danube deep-sea fan. CI Citation: Paul Wintersteller (seafloor-imaging@marum.de) as responsible party for bathymetry raw data ingest and approval.
Description of the data source:
During the RV MARIA S. MERIAN cruise MSM34-2 Kongsberg EM122 multibeam echosounder with a nominal sounding frequency of 11.5 to 12.5 kHz was utilized. 288 beams (and up to 864 soundings in equidistant and dual swath mode) are formed for each ping with a 2°(Tx)/2°(Rx) footprint while the seafloor is detected using amplitude and phase information for each beam sounding. For further information consult https://www.km.kongsberg.com/. Based on the observations during MSM34-1 the bathymetry of MSM34-2 mainly consists of the detailed mapping to the gas hydrate distribution area. Responsible person during this cruise / PI: Felix Gross (GEOMAR), Joerg Bialas (GEOMAR).
