Abstract:
Swath sonar bathymetry data used for that dataset was recorded during RV ALKOR during cruise AL632 using Kongsberg EM2040 multibeam echosounder. The cruise took place between 06.05.2025 - 13.05.2025 in the German Baltic Sea. The approximate average depth of the mapped area is around 18m. To enhance MBES data accuracy, sound velocity profile (SVP) casts were conducted in the vicinity of the working area prior to and after each survey using a CTD. In the case of the Adlergrund_West area the SVP after the survey was applied via the processing software Qimera (https://qps.nl/qimera/#). Data were manually edited for false measurements using 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. Two working areas are located within (Adlergrund West) and adjacent to (Reference Area) the Marine Protected Area Adlergrund. The mapping has been conducted for baseline habitat studies in the area.
