Purpose | |
Abstract | Scientific work during cruise MSM64 emphasized on a detailed mapping of water mass properties along 47 to 48 N that was combined with comprehensive measurements of the current system. In addition to ship- based observations, recovery and redeployment of deep-sea moorings at the western and eastern boundaries of the North Atlantic was conducted. These serve to determine the export and import rates of subpolar or subtropical water masses in these regions. In addition to this program, the two multibeam echo-sounder systems installed in the vessels hull Kongsberg EM712 and EM122 were calibrated, and the required sea acceptance test for the EM712 device was carried out by a technical-scientific team. Further acquisition information were not provided by the responsible party. |
