Raw bathymetry data were collected using the ship's own Kongsberg EM122 multibeam echosounder during the RV MARIA S. MERIAN cruise MSM39 (Linking past and present in the North Atlantic). The cruise took place between 2014-06-07 and 2014-06-25 (St. John's, Canada – St. John's, Canada). The main goals of the cruise were to study the modern deep water spreading from the Labrador Sea to the Laurentian Fan and to obtain sediment cores to investigate the history of subtropical/subpolar gyre interactions and deep-water formation. Bathymetry was collected throughout the whole cruise along with the sub-bottom profiling (Parasound) data in order to find suitable coring locations and to get an overview of deposition regimes and mechanisms. Two sound velocity profiles (SVPs) were collected using the ship's own AML oceanographic sound velocity probe: one in working area A south west of Grand Banks, one in working area B south east of Grand Banks. However, the measured SVPs used for the downslope and upslope transects were not accurately representing sound velocity in shallow waters leading to strong artificial beam deformation in water depths shallower than 500 m. The data are archived at the Federal Maritime and Hydrographic Agency of Germany (Bundesamt für Seeschifffahrt und Hydrographie, BSH) and provided to PANGAEA database for data curation and publication. Data are unprocessed and therefore contain incorrect depth measurements (artifacts). Data can be processed e.g. with the open source software package MB-System (Caress, D. W., and D. N. Chayes, MB-System: Mapping the Seafloor, http://www.mbari.org/products/research-software/mb-system/, 2022). ** For all details see the full metadata description at "https://doi.pangaea.de/10.1594/PANGAEA.983165"! ** These data should not be used for navigational purposes.
