Expertise
Our main research comprises the investigation of sediments and bedrock from the ocean, as well as geological, geochemical and geophysical investigations at the seafloor and within the water column. Main focus of our marine research is on processes which are responsible for mass and energy exchange between lithosphere and ocean sphere. For this purpose we use several modern technologies (anchorages, side scan sonar, ship\'s sonar, video controlled devices, ROVs, AUVs, etc.) - beneath the research vessels.

Large amounts of methane either as free gas or dissolved in porewater are present in sediment deposits along continental margins. Under condition of high pressure and cold temperature, methane and other gases form ice-like gas hydrates. A focus of our research is on understanding the formation, structure and dynamics of gas hydrates in natural systems and their influence on the marine environment. Like groundwater springs on land, fluids and gas circulate through the upper sediment sequences of the seafloor and escape at so-called cold vents or cold seeps. Study objects are precipitates (carbonates, gas hydrates, and barites) and chemoautotrophic communities which are present at those seeps when methane is oxidized in the sediments.
