Abstract:
Swath sonar bathymetry data were acquired during cruise AL652/2 with the research vessel RV ALKOR using a hull-mounted Kongsberg EM2040 multibeam echosounder (MBES). The cruise took place between 25.05.2026 - 02.06.2026 in the German Baltic Sea. The approximate depth range of the mapped area is between 10-20 m. 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 Sound Velocity Probe. The data set includes data from the 'Adlergrund', located within the Pommeranian Bay/Rønne Bank Nature Conservation Area (NCA). The survey was carried out to support baseline habitat studies in this region. Data processing involved the application of a weak spline filter and manual cleaning to remove erroneous soundings, performed using Qimera (https://qps.nl/qimera/#). A bathymetric raster was generated and exported in GeoTIFF format with a spatial resolution of 0.25 m (negative depth values), referenced to WGS84 as the vertical datum and projected in UTM coordinates.
