Ziel der Reise / Objectives of Cruise:

This cruise leg combines activities of the 6th EU framework project HERMES and the German 'Geotechnologien' project MUMM II and investigates seep systems of the NW and NE Crimean margin. These consist of numerous fluid- and gas-escape structures outcropping in water depths between 200 and 2100 m which include actively gas emitting mud volcanoes and microbial reefs associated with gas seeps. The rising fluids carry hydrocarbons, mostly methane, to the seabed surface, which build the basis for rich and abundant microbial life. On the basis of geophysical, geochemical and microbiological data from various seep structures collected during M 72/2 we aim at gaining a better understanding of the distribution and functions of the anoxic seep ecosystems. The objectives are to understand the controls and mechanisms of chemical element transport and breakdown by seep microbiota, and to obtain insight in the element cycling and export from the seabed into the water column at different types of fluid seeps in the Black Sea. These goals will be achieved by detailed near-field mapping of selected habitats using the French autonomous underwater vehicle (AUV) ASTERX (IFREMER) followed by detailed geochemical in-situ measurements and specific sampling of mud, fluids, carbonates and biota along geochemical gradients. Sampling and in-situ measurements will be performed with the German ROV QUEST (MARUM).
