Gas hydrates in mud volcanoes of the Anaximander Mountains (Eastern Mediterranean)
In the frame of this research cruise the distribution, the quantity and the dynamics of gas hydrates in submarine mud volcanoes of Anaximander Mountains (northeastern Mediterranean) will be investigated. Mud volcanoes are considered globally important emitters of climate relevant methane gas. In the area numerous mud volcanoes are known - four of them shall be explored along a water depth profile. Based on micro-bathymetric detailed maps which had been issued earlier, sediment cores will be gathered under in situ pressure from selected locations at the seafloor. By this more exact quantities of hydrate can be determined. Heat flow measurements in the sediments will be acquired using a heat-flow lance. During the dives with our remotely operated vehicle (ROV) emitted gas quantities will be quantified, and the colonisation by chemosynthetic organisms will be explored as well.
