Purpose
Abstract MSM54 was dedicated to the re-deployment of moored instrumentation as well to vertical surveys of the water column. Moored instrumentation, programed for high temporal resolution sampling (<1 hour) and installed at distinct locations in the Labrador and Irminger Seas, record the local evolution of physical properties (temperature, salinity, density, currents). Though multibeam data has been recorded it was not the main focus of the cruise and no acquisition information has been provided by the responsible party.
