Multibeam bathymetry raw data (Kongsberg EM2040 entire dataset) of RV ALKOR during cruise AL644

DOI

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.

These data should not be used for navigational purposes.
