Abstract | The cruise MSM48 studied the region off NW Africa and the Madeira Abyssal Plain, which is one of the world’s most productive regions due to the presence of year-round upwelling und terrestrial dust input fertilizing the ocean. 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. |
