Multibeam bathymetry processed data (KONGSBERG EM712 multibeam echosounder) was collected onboard RV HEINCKE during cruise HE622 in the German North Sea (2023-06-06 - 2023-06-20). The raw data (.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 dynamic surface (shallow Mode) -> 3.Apply Spline Filter (Medium/Weak) > 4. Finalize with manual 2D and 3D editing, -> 5.Export in GeoTIFF format and projected in the UTM32N coordinate system (EPSG:32632). The bathymetry dataset here is gridded at 0.50 m resolution. The data products were created in the context of the DAM (German Marine Research Alliance), CONMAR research project. ** For all details see the full metadata description at "https://doi.pangaea.de/10.1594/PANGAEA.972394"! ** These data should not be used for navigational purposes.
