Purpose
Abstract The primary goal of this cruise was to quantify the role of diffusive and advective pathways connecting water within the bottom boundary layer (i.e. the water directly affected by sediment processes) to the pelagic and surface ocean. This exchange can be a consequence of either enhanced mixing close to the bottom or advective processes. Though multibeam has been recorded during the cruise, it was not a major focus and the responsible party provided no acquisition information.
