A focus of our research is to understand the formation, structure and dynamics of methane hydrates in natural systems and their influences 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, hydrates, and barites) and chemoautotrophic communities that are present at seeps when methane is oxidized in the sediments.
