Multibeam bathymetry processed data (Kongsberg EM 2040 working area dataset) of RV ALKOR during cruise AL628, west of Little Belt, Baltic Sea

Multibeam bathymetry processed data (EM 2040 multibeam echosounder) of RV ALKOR during cruise AL628 in the Baltic Sea. The raw data (.kmall) were processed using QPS Qimera software (v 2.6), 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/Strong) > 4. Finalize with manual 2D and 3D editing, -> 5.Export in GeoTIFF format and projected in the UTM32N coordinate system (EPSG:32632). The produced rasters are named AL628_EM2040_'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.

Multibeam bathymetry processed data (Kongsberg EM2040 working area dataset) of RV ALKOR during cruise AL644, Baltic Sea

Swath sonar bathymetry data recorded during AL644 on RV ALKOR using the hull-mounted Kongsberg EM2040 multibeam echosounder. The cruise took place between 17.11.2025 - 28.11.2025 in the German Baltic Sea. The approximate depth range of the mapped areas is between 10-30m. To improve MBES data quality, sound velocity profile (SVP) casts were conducted in the vicinity of the mapped area prior to and after each survey using a CTD. The data set includes data from the 'Adlergrund' (ADG), located within the Pommeranian Bay/Rønne Bank Nature Conservation Area (NCA), from the 'Kadet Trench ('KDR') NCA and the Fehmarn Belt ('FB') NCA. The mapping has been conducted for baseline habitat studies in the area. Data were manually edited for false measurements using Qimera (https://qps.nl/qimera/#). A raster was calculated and stored in GeoTIFF format with a 0.5 m resolution (negative values), WGS84 as vertical datum and UTM as a projection. The mapping has been conducted for baseline habitat studies in the area.
