Multibeam bathymetry processed data (Kongsberg EM 122 multibeam echosounder) of RV MARIA S. MERIAN during cruise MSM96 in the North-East Atlantic (2020-10-120 - 2020-11-9). The raw data (Kongsberg .all format) were processed using QPS Qimera software (v 1.7), based on the following workflow: 0.Raw data -> 1.Apply correct Sound Velocity Profiles -> 2.Create CUBE surface (Deep Mode) -> 3.Apply Spline Filter (Medium/Weak)- > 4. Finalize with manual 2D and 3D editing, -> 5.Export in GeoTIFF format and projected in the UTM28N coordinate system (EPSG:32628). The produced rasters are named MS96_WA1_PAP_100m and MSM96_WA2_IAP_100m (WA=Working Area, PAP=Porcupine Abyssal Plain, IAP=Iberian Abyssal Plain, and 100m is the cell size). The data products were created in the context of the DAM (German Marine Research Alliance), MareHub (Helmholtz) & iAtlantic (EU) research projects.
