Gridded bathymetry from multibeam echosounder EM122 data of the cruise MSM35

The aim of Maria S. MERIAN voyage MSM35 was to conduct marine controlled source electromagnetic (CSEM) measurements in the Danube Delta, Black Sea, to identify suitable gas hydrate deposits for a future MEBO drilling test site for methane production and CO2 sequestration in hydrate form. Marine CSEM is a geophysical exploration method to derive the electrical properties, i.e. resistivity of the seafloor. Gas hydrates and free gas are electrically insulating and replace conductive pore fluid.

Gridded bathymetry from multibeam echosounder EM122 data of the cruise MSM33 (2013)

Bathymetry based on data recorded during MSM33 between 02.11.2013 -and 10.11.2013 in the Black Sea. The overarching goal of MSM33 was the investigation of the biology and biogeochemistry of the central Black Sea with a special consideration of the processes at pelagic redoxicline. The bathymetric focus laid upon the slope structure especially at the Archangelsky Ridge.

Gridded bathymetry from multibeam echosounder EM122 data of the cruise MSM34/1 (2013)

Bathymetry based on data recorded during MSM34-1 between 09.12.2013 and 27.12.2013 in the Black Sea. The main objective of this cruise was the localization and characterization of suitable gas hydrate deposits on the Danube deep-sea fan.
