Multibeam bathymetry processed data (NORBIT WBMS entire dataset) from 2021, Laacher See, Germany

This dataset contains processed bathymetric data of the volcanic crater lake Laacher See in Germany recorded on 13-14 September 2021, acquired for the purpose of describing the lake sedimentary infill and volcanic degassing processes occurring in the crater. It has a coverage of 2.81 km², which corresponds to ca. 84% of the total lake surface area. The nearshore zone was not mapped due to vegetation growth limiting the data quality. Depths are expressed in meters below lake level, ranging from 2.4 m to 50.5 m. The bathymetric data was acquired using a Norbit WBMSe Wideband Multibeam Sonar from the Flanders Marine Institute (Vlaams Instituut voor de Zee, VLIZ) and the system was operated at a source frequency of 400 kHz with a maximum swath angle of 150°, transmitting 512 beams with a beam width of 0.9° x 1.9°. Sound velocity profiles were collected throughout the survey to account for temporal variations in water-column sound velocity. Processing of the raw data was done using Qimera 2.5.1 (QPS) and included correction for pitch, roll and heading offsets during acquisition, and manual removal of artefacts such as gas bubbles, vegetation and inconsistent soundings in overlapping swaths. From the processed data, a bathymetric grid with a ~1m cell size was constructed.

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.

Multibeam bathymetry processed data (Kongsberg EM2040 working area dataset) of RV ALKOR during cruise AL652/2, MPA Fehmarnbelt, Baltic Sea

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 15-30m. 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 Sound Velocity Probe. The data set includes data from an area called 'Oejet', which is a part of the Nature Conservation Area (NCA) 'Fehmarnbelt', located in the western Baltic Sea. 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. The dataset consists of two surveys (Stations AL652-2_65, AL652-2_77) that were combined into a single final grid.
