Multibeam bathymetry raw data (Kongsberg EM712 entire dataset) of RV HEINCKE during cruise HE659

Raw multibeam bathymetry data from the Kongsberg EM712 was acquired during the RV Heincke cruise HE659 in the German Bight in April 2025. The data was generally acquired during calm seas in water depths between 20 and 50 m. Primarily three different regions were surveyed (Borkumer Reef Ground, Sylt Outer Reef, and Helgoland). Generally the data is comprehensive and overlapping swaths creating a continuous bathymetry were archived. In some areas the data was acquired complementary to sidescan sonar surveys and individual tracks do not overlap. Data are unprocessed and therefore may contain some incorrect depth measurements (artifacts) without further processing. No tide variations are applied. Sound velocity profiles were acquired regularly. Overall, it appears that the data quality is rather good. The gridded data showed relatively few obstacles.

Multibeam bathymetry processed data (Atlas Hydrosweep DS 3 echo sounder entire dataset) of RV POLARSTERN during cruise PS151, Atlantic Ocean

Multibeam data were collected during RV Polarstern cruise PS151 (2025-11-13 to 2025-12-12). Multibeam sonar system was Atlas Hydrographic Hydrosweep DS 3 multibeam echo sounder. Data are processed with Caris HIPS, including sound velocity correction with SV data from CTDs and World Ocean Atlas 23 (https://www.ncei.noaa.gov/archive/accession/NCEI-WOA23), tidal correction with TPXO9_atlas_v5 (https://www.tpxo.net), and manual cleaning. The soundings are combined in daily files, the format is XYZ ASCII (<Lon> <Lat> <Depth in meters, positive up, relative to mean sea level>). Additional grids have been computed with depth dependent cell size to visualize the data. These grids are not meant for scientific analysis or navigation, but for overview purposes only.

Fernerkundung atmosphaerischer Parameter und deren Nutzung fuer die Untersuchung klimarelevanter Prozesse sowie von Spurenstofftransporten und -umsetzungen

Untersuchung klimarelevanter Prozesse im mesoskaligen Bereich durch die Erfassung meteorologischer Groessen und Spurenstoffe mit Hilfe von bodengebundenen, flugzeug-, ballon- oder satellitengetragenen Instrumenten. Dazu gehoeren die Entwicklung und Erprobung neuer Verfahren und Messgeraete zur Fernerkundung atmosphaerischer Parameter. Mit Ballonmessungen werden die photochemischen Umsetzungen und der Tagesgang von Spurenstoffen in der Atmosphaere verfolgt. Beitraege zu umweltrelevanten Problemen (z.B. Ozonloch) ergeben sich aus den bodengebundenen Spurengasmengen. Teilziele sind: Einsatz von Michelson-Interferometern, Erprobung bodengebundener Fernmessverfahren fuer Messungen in der Troposphaere (SODAR, RADAR, RASS), Verfahren zur Gewinnung von Landoberflaechenparametern, meteorologischen Vertikalprofilen und Spurengasverteilungen aus Satellitendaten, Untersuchung von Transportvorgaengen und zeitlichem Verlauf von Konzentrationsaenderungen und photo-chemischen Umsetzungen.

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.

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