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.

Stadtklimatologie, Messung der Inversionshoehe ueber Koeln mittels Sodar

Es ist das Ziel des Vorhabens, ein physikalisch realistisches Rechenmodell zu schaffen, dass den Auf- und Abbau der naechtlichen und winterlichen Inversionen ueber dem Stadtgebiet vorherzusagen ermoeglicht. Die Kontrolle und Erfassung der Phaenomenologie erfolgen durch vertikal sondierenden Schallradar und staendige Messung der Strahlung, Feuchte, Temperatur und des Windes. Der Aufbau eines Messnetzes innerhalb des Stadtgebietes wird vorbereitet. Bereits vorhandene Windmessungen werden ausgewertet und mit gleichzeitigen Schadstoffmessungen korreliert.

Multibeam bathymetry processed data (Atlas Hydrosweep DS 3 echo sounder entire dataset) of RV POLARSTERN during cruise PS132, Transit, Atlantic Ocean

Multibeam data were collected during RV Polarstern cruise PS132 (2022-08-31 to 2022-09-29). 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, XBTs and World Ocean Atlas 18 (https://www.ncei.noaa.gov/archive/accession/NCEI-WOA18), 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 blockmedian 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.

Multibeam bathymetry raw data (Kongsberg EM712 entire dataset) of RV HEINCKE during cruise HE642

Raw multibeam bathymetry data from the Kongsberg EM712 were acquired during the RV Heincke cruise HE642 in the German Bight in June 2024. The data was generally acquired during calm seas, although bad weather periods occurred mainly during the later stages of the cruise. Water depths range between 20 and 50 m. Primarily, two different regions were surveyed (Borkumer Reef Ground and Sylt Outer Reef). 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, where 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 good but compromised by a slightly tilted centre swath sector. The gridded data shows relatively few artefacts.

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.
