Multibeam bathymetry processed data (RESON T51-P multibeam echosounder) were collected onboard RV ALKOR during cruise AL590 in the German Baltic Sea (2023-03-17 - 2023-03-31) at Zingst, Rügen. The raw data (QPS .dbformat) 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 UTM33N coordinate system (EPSG:32633). The produced rasters are named AL590_T51_'working area'_'resolution in cm' . The bathymetry dataset here is gridded at 0.25 m and 0.50 m resolution. The data products were created in the context of the DAM (German Marine Research Alliance), CONMAR research project.

These data should not be used for navigational purposes.
