Purpose
Abstract The main research interests of cruise M13/1 were biological topics: A main topic was to proof the existence of a bottom-nepheloid-layer in the Northern Atlantic as well as to study microbial activities in upper sediment layers. Therefore a sediment sampling systems like a multicorer and a new bottom water sampler were used. During the entire cruise Hydrosweep Data were collected- The quality of profiles varies coherent to weather conditions and ship course. Though multibeam data was recorded, it was not the main focus of the cruise and no further information have been provided by the responsible party.
