| Abstract | 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 BMBFfunded project Sugar2. A combination of amplitude (for the central beams) and phase (slant beams) is used to provide a measurement accuracy practically independent of the beam pointing angle. Beside the depth values, the EM122 provides also backscatter information and pseudo-sidescan images. |
