The cruise took place between 25.05.2026 - 02.06.2026 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. The data set includes survey data from the working areas 'Adlergrund', located within the Pommeranian Bay/Rønne Bank Nature Conservation Area (NCA) and the Fehmarn Belt ('FB') NCA. Data from transits in between the working areas have also been recorded and are provided here. The mapping has been conducted for baseline habitat studies in the area.
