M87/2 COSY set out to investigate the geological processes that may cause significant migration of carbon from the subsurface into the ocean and ultimately into the atmosphere. Understanding these processes is fundamental for understanding episodic climate forcing by geological processes, for assessing the role that subsurface fluid migration plays for slope stability, and for assessing the economic potential of hydrate-bearing sediments as a future energy source. As such the cruise contributed mainly to two scientific projects: the Excellence Cluster Future Ocean and here in particular the sub-project Ocean Controls, and the BMBF funded project Sugar2.The two main objectives of the cruise were (1) to find out if the Giant Gjallar Vent on the north-western Vøring Margin can serve as a window to the deeper structures of the Vøring Basin, which were strongly influenced by hydrothermal activity related to break-up volcanism, and (2) to provide a controlled-source electromagnetic (CSEM) data set in an area where ... : METEOR-Berichte ...
