Physical oceanography during RV HEINCKE cruise HE645

Conductivity-temperature-depth profiles were measured using a Seabird SBE 911plus CTD during RV HEINCKE cruise HE645. 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.

Raw data of physical oceanography during RV HEINCKE cruise HE642

Raw physical oceanography data was acquired by a ship-based Seabird SBE911plus CTD-Rosette system onboard RV HEINCKE . The CTD was equipped with duplicate sensors for temperature (SBE3plus) and conductivity (SBE4) as well as one sensor for oxygen (SBE43). Additional sensors such as a WET Labs C-Star transmissometer, a WET Labs ECO-AFL fluorometer (FLRTD) and an altimeter (Teledyne Benthos PSA-916) were mounted to the CTD. The data was recorded using pre-cruise calibration coefficients. No correction, post-cruise calibration or quality control was applied. Processed profile data are available via the link below.

Ursachen und Auswirkungen genetischer, taxonomischer und funktioneller Diversität in marinen Ökosystemen

Ich möchte prüfen, ob und unter welchen Bedingungen marine Ökosysteme alternative stabile Zustände hoher und niedriger Diversität und Produktivität ausbilden ('multiple stable states hypothesis', MSS). Modellstudien aus Seen und eigene Experimente an Felsküsten zeigen, dass durch Veränderungen der Konsumentenfauna und der Nährstoffzufuhr drastische Produktivitäts- und Diversitätsveränderungen hervorgerufen werden können. Für marine Systeme ist jedoch völlig unklar, ob es sich dabei um durch Rückkopplungen stabilisierte Zustände handelt. Diese Frage ist von großer theoretischer sowie angewandter Bedeutung, da eine Bestätigung der MSS bedeuten würde, dass die unerwünschten Veränderungen, die z. B. durch Eutrophierung oder Überfischung entstehen, nicht einfach durch Reduktion der Nährstofffracht oder des Fischereidrucks rückgängig zu machen wären. Ich möchte in diesem Projekt drei wichtige Teilsysteme bearbeiten: (1) benthische Hartbodengemeinschaften, (2) Planktongemeinschaften, (3) Fischbestände. Dazu werde ich kontrollierte Freilandexperimente durchführen sowie auf großer räumlicher und zeitlicher Skala erhobene Monitoringdaten analysieren. In Zusammenarbeit mit Modellierern in Kanada und Deutschland werde ich diese Datensätze auf das Vorkommen multipler stabiler Zustände Puffermechanismen und nichtlinearer Rückkopplungen untersuchen. Ziel ist dabei ein Modell zur Regulation der Produktivität und Artendiversität durch Nährstoffe und Konsumenten zu erarbeiten.
