Abstract:
Multibeam bathymetry raw data was recorded in the North Atlantic during cruise M168 that took place between 2020-11-08 and 2020-12-08. The data was collected using the ship's own Kongsberg EM 122. This data is part of the DAM (German Marine Research Alliance) underway research data project. A sound velocity profile (SVP) was applied on the data for calibration. SVP data are part of this dataset publication.
