Purpose | |
Abstract | The overarching aim of cruise MSM49 was to assess the medium-sized pelagic fauna and their role within the pelagic community in relation to water mass properties, with special emphasis on oxygen minimum zones (OMZ) of different intensity, and the influence of a shallow seamount reaching into the realm of the fauna which performs extensive diel vertical migrations. Though multibeam data was recorded it was not the main focus of the cruise and no further informations have been provided by the responsible party. |
