The North Sea is one of the economically most important European margins with respect to the occurrence and exploitation of natural gas. The areas include surface structures such as gas seeps, pock marks and carbonate chimneys derived from diffuse or focused emissions of methane and around which methane transformations will be studied. Many gas seeps have been discovered in the North Sea associated with microbial mats, carbonate reefs and cold water corals by the Black Sea north-western shelf and slope
As the largest anoxic basin on earth, the Black Sea provides an ideal model system for studies of anaerobic methane oxidation. The entire sea floor below 150 m is overlain by an anoxic water column, and sulfate reduction, methanogenesis and methane oxidation are the totally dominant terminal processes of carbon flux in the sediments. Anaerobic methane oxidation takes place in the subsurface and at the sediment surface at gas vents. The occurrence of methane seeps and carbonate structures have been mapped through extensive acoustic surveys by the local partners GeoEcoMar and IBSS.
Other ocean margin sites
Other ocean margin regions will be studied after careful selection depending on their relevance for the project and on cruise and sample availability. |
