Ziel der Reise / Objectives of Cruise:

The r/v Meteor M54 cruise adresses basic objectives of and is of central importance to the "Sonderforschungsbereich" SFB 574: Volatiles and Fluids in Subduction Zone: Climate Feedback and Trigger Mechanisms for Natural Disasters, During the 3rd leg, M54/3A, the focus was on identification and sampling of sites influenced by venting of methane-rich fluids. Chemoautotrophic benthic communities and carbon chimneys, crust and other authigenic mineral precipitates were obtained. TV-guided deep-sea instrumentation was deployed in order to quantify the amount of fluids released from the seafloor and the turnover of methane in the sediments as well as at the seafloor and in the water column. The main geological features investigated which show signs of fluid venting are carbonate mounds, subducted scarps and submarine land slides.
