Steuerrandmessungen Elbe und Jade/Weser 2012

Die BAW (Bundesanstalt für Wasserbau) führt im Auftrag der WSV (Wasserstraßen- und Schifffahrtsverwaltung des Bundes) umfangreiche F&E-Untersuchungen (Forschung- und Entwicklung) zur Klimafolgenforschung sowie zur Auswirkung geplanter Ausbaumaßnahmen an Seeschifffahrtsstraßen durch. Hierfür werden hochauflösende dreidimensionale numerische Simulationsmodelle eingesetzt. Die Aussagefähigkeit und Qualität der Simulationsergebnisse ist hierbei entscheidend von der Güte der Steuerung an den Modellrändern abhängig. Die Modelltopographie (= "Rechengitter") und die verwendeten hydrologischen Bedingungen auf den Modellrändern sollten möglichst einen identischen Zeitraum repräsentieren. Da die Modelltopographien für die Modellgebiete des "Jade-Weser" und des "Elbe" - Modells der BAW im Jahr 2012 neu aufgebaut worden sind, ist im Sommer 2012 ein Messprogramm zur Erfassung der hydrologischen Randbedingungen durchgeführt worden. Zu diesem Zweck hat die BAW - Dienstort Hamburg ein Messnetz aus insgesamt 13 Beobachtungsstationen entlang der Steueränder der numerischen Modellsysteme eingerichtet. Mindestens über den Zeitraum eines "Nipp-Spring-Zyklus" (~ 14 Tage) wurden in verschiedenen Gerätekonfigurationen folgende Parameter gemessen: CTD-Messungen (Conductivity, Temperature, Depth): - Wasserspiegelauslenkung (Tidekurve) - Salinität - Temperatur - Trübung (teilweise) Für Zwecke der Modellvalidierung sind auf einem ca. 10 km parallel in das Modellgebiet verschobenen Rand ADCP-Messungen (Acoustic Doppler Current Profiler): - Strömungs- und - Seegangsmessungen (teilweise) durchgeführt worden. Soweit verfügbar sind Daten der von der WSV betriebenen Pegelstationen einbezogen worden. Für meterologische Informationen stehen Daten des DWD zur Verfügung (Quelle: Deutscher Wetterdienst).

Physical oceanography during RV HEINCKE cruise HE601

Conductivity-temperature-depth profiles were measured using a Seabird SBE 911plus CTD during RV Heincke cruise HE601. The CTD was equipped with duplicate sensors for temperature (SBE3plus), conductivity (SBE4) and oxygen (SBE43). Additional sensors such as a WET Labs C-Star transmissometer, a WET Labs ECO-AFL fluorometer and an altimeter (PSA-916 Teledyne (Benthos)) were mounted to the CTD. Temperature, conductivity and oxygen sensors are calibrated by the manufacturer once a year before being mounted in January. They are used throughout the year and no post-cruise or in-situ calibration is applied. All other sensors are calibrated irregularly. Data were connected to the station book of the specific cruise as available in the DSHIP database. Processing of the data including removal of obvious outliers followed the procedures described in CTD Processing Logbook of RV Heincke (hdl:10013/epic.47427). The processing report for this dataset is linked below.

Physical oceanography during RV MARIA S. MERIAN cruise MSM123

Physical oceanography data was acquired by a ship-based Seabird SBE911plus CTD-Rosette system onboard RV MARIA S. MERIAN during research cruise MSM123. The CTD system is comprised of a Seabird SBE911plus including dual respectively redundant sensor and pump packages. The SBE11plus Deck Unit remains on board in a laboratory and supplies on one hand power to the SBE9plus underwater unit, on the other hand data telemetry between the SBE9plus and a measurement PC. The SBE9plus underwater unit itself holds a pressure sensor and is interfacing with dual SEB3 temperature, SBE4 conductivity and SBE43 oxygen sensors, as well as two SBE5 pumps to provide a pumped water supply past each sensor. The system also carries an optical FLNTU sensor to measure a combination of back-scattering, turbidity, and chlorophyll-a. To quantify the photo-synthetically active radiation a PAR sensor is installed as well.
