Ziel der Reise / Objectives of Cruise:

This cruise contributed to the projects MUMM and EXOCET as well as to the objectives of the virtual institute "MarTech" of the Helmholtz foundation. In the framework of the previous Project METROL the question was addressed how methane turnover is controlled in shallow gassy sediments. Objectives of Exocet and MarTech are testing of underwater technology, including payloads of two platforms, the ROV Cherokee and the underwater benthic crawler MOVE. Tasks included A) The quantif. of the microbial turnover of methane in gassy sediments as well as the characterisation of the geochemical conditions B) Collection of gas and sediment from natural gas seeps using ROV pushcores and gas collectors. C) Measuring in situ oxygen consumption with chamber incubations, profiling and 2D optode set up using the MOVE crawler E) identification of microorganisms responsible for methan turnover.
