Gridded bathymetry from multibeam echosounder HS-DS2 data of the cruise M52/1 (2002)

Bathymetry based on data recorded during M52-1 between 02.01.2002 and 01.02.2002 in the Black Sea. The cruise was focused on studying the distribution, structure and architecture of gas hydrate deposits in the Black Sea as well as their relationship to fluid migration pathways. While high-resolution geoacoustic investigation tools covering a whole range of frequencies and techniques render detailed images of near-surface gas hydrates and associated fluid migration pathways.

Gridded bathymetry from multibeam echosounder EM120 data of the cruise M72/1 (2007)

Bathymetry based on data recorded during M72-1 between 07.02.2007 and 20.02.2007 in the Black Sea. The main focus of the cruise were gas vents and seeps in the north-western Black Sea below 700 m water depth which is the zone of gas hydrate stability. The main target area was the deep Dnepr Canyon west of the Crimea Peninsula where previous investigations had indicated the occurrence of gas seepage.

Gridded bathymetry from multibeam echosounder EM120 data of the cruise MSM15/1 (2011)

Bathymetry based on data recorded during MSM15-1 between 12.04.2010 and 08.05.2010 in the Black Sea. The aim of this cruise was to quantify the concentration and uptake of oxygen at the anoxic boundaries in the water column and at the sediment water interface of the Black Sea, in parallel with the measurement of nitrogen, carbon, sulfur and iron fluxes (HYPOX project).
