Messgeräteplattform & Sensorpaket zum hybriden Monitoring von Fließgewässern

Das Wasserfahrzeug als Messgeräteplattform besteht aus einem durch zwei Motoren angetriebenen Katamaran. Das Sensorpaket beinhaltet Messtechnik zur gleichzeitigen Erfassung der Gewässergüte (Multiparametersonde), der Gewässertopografie (Vertikal-Echolot, Seitensichtsonar) sowie hochaufgelöster Strömungsverhältnisse im Fließquerschnitt (9-strahlige Akustik-Doppler-Sonde). Weiter ist ein LiDAR-Sensor zur Erfassung und Kartierung der Ufervegetation bzw. Bebauung an und in Gewässerrandstreifen vorgesehen. Für eine georeferenzierte Datenerfassung soll die Messgeräteplattform mit einem GNSS-Empfänger (RTK-Genauigkeit) ausgestattet werden und ergänzend eine Zielmarke erhalten, sodass ein Tracking über Kopter und Vermessungsdrohnen (UAVs) ermöglicht wird. Mit den Messgeräten sollen Forschungsfragen in den Handlungsfeldern „Digitalisierung der Wasserwirtschaft“, „Resilienz gegenüber Hoch- und Niedrigwasserereignissen“ und „Neue Verfahren zur Datenerhebung in der Wasserwirtschaft“ beantwortet werden. Grundlegend wird mit dem Großgerät die Aufnahme von Messdaten angestrebt, die möglichst viele gewässerbezogene Parameter enthalten. So soll eine Datenbasis geschaffen werden, welche die Grundlage für die Beantwortung der folgenden Forschungsfragen darstellt: - Inwiefern sind datengetriebene Modelle in der Lage, strukturelle Veränderungen im Gewässer abzubilden und diese auf Wasserstand-Abfluss-Beziehungen zu übertragen bzw. ebendiese zu aktualisieren? - Lassen sich räumliche und raumzeitliche (Auto-) Korrelationen von Niederschlag- und Abflussdaten mittels maschineller Lernverfahren (ML) (insbesondere Long Short-Term Memory-Methoden) modellieren und welchen Einfluss haben Menge und Qualität der Eingangsdaten auf die Genauigkeit der Systemantwort „Abfluss“? - Wann und wo finden Sedimentationsprozesse in Speichersystemen (z. B. Talsperren) statt und können diese durch gezielte Bewirtschaftungspläne verhindert werden? - Welche Auswirkungen hat die Volumenänderung auf die Bewirtschaftung von Speichersystemen und die Bereitstellung bzw. Aufrechterhaltung der Wasserversorgung?

Munition pile inventory in the German Baltic Sea, 2017 et seq

The publication series contains spreadsheets of munitions, their properties (e.g., number of objects, variability, burial state), and the parameters characterising their environmental (e.g., munition compound concentrations and current velocity) and maritime (e.g., distance to various maritime uses and traffic density) surroundings in the German Baltic Sea. Data are collected over numerous cruises starting in 2017. The purpose of data acquisition is to understand the distribution and properties of munitions in German waters as well as the hazards and risks they pose to maritime uses. Munitions are annotated in larger area datasets (usually multibeam echosounder or sidescan sonar data), assessed in detail (usually visually in photomosaics or videos), and analysed using an array of geospatial analysis methods.

Multibeam bathymetry raw data (Kongsberg EM2040 entire dataset) of RV ALKOR during cruise AL644

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.

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 raw data (Atlas Hydrosweep DS 3 echo sounder entire dataset) of RV POLARSTERN during cruise PS142

Multibeam data were collected with RV Polarstern along the route of cruise PS142 and data acquisition was continuously monitored during the survey. Multibeam sonar system was Teledyne/Atlas Hydrosweep DS3. SVPs were retrieved from CTD data and synthetic profiles from World Ocean Atlas 18. SVPs were processed with HydrOffice SoundSpeedManager (https://www.hydroffice.org/soundspeed/main) and extended with World Ocean Atlas 18 (https://www.ncei.noaa.gov/archive/accession/NCEI-WOA18). SVP data were applied during acquisition. Multibeam data are unprocessed and may contain outliers and blunders and should not be used for grid calculations and charting projects without further editing. The raw multibeam sonar data in Teledyne Reson multibeam processing format (.s7k) were recorded with Teledyne PDS software. Raw data files can be processed using software packages like CARIS HIPS/SIPS. For updated vessel configuration files check further details.

Multibeam bathymetry processed data (Atlas Hydrosweep DS 2 echo sounder entire dataset) of RV POLARSTERN during cruise ANT-XXIII/8 (PS69), Southern Ocean

Multibeam data were collected during RV Polarstern cruise ANT-XXIII/8 (2006-11-23 to 2007-01-30). Multibeam sonar system was Atlas Hydrographic Hydrosweep DS 2 multibeam echo sounder. Data are processed with Caris HIPS, including sound velocity correction with SV data from CTDs 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 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.
