Physical oceanography during RV HEINCKE cruise HE630

Conductivity-temperature-depth profiles were measured using a Seabird SBE 911plus CTD during RV HEINCKE cruise HE630. 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.

Klimawechsel im späten Eifelium: Auswirkungen auf tropische Korallenfaunen

Während des frühen bis mittleren Devon (ca. 418-383 Mio. Jahre) herrschten Treibhausverhältnisse auf der Erde. Die Klimaentwicklung zu jener Zeit führte schließlich zu einem Höhepunkt an Diversität, Größe und Verbreitung von Riffen im mittleren Devon (Eifelium und Givetium). Doch auch während des Klimax im Mittel-Devon kam es vermehrt zu Klimaschwankungen, die in mehr oder weniger schweren biotischen Krisen resultierten. Eine dieser Krisenzeiten entspricht dem Kacak-Event während des späten Eifelium, der als Schwarzschiefer und Hornstein-Horizont in marinen Sedimenten global nachgewiesen ist. Das mehrphasige dysoxische/anoxische Ereignisintervall beschränkt sich auf die kockelianus und ensensis Biozone (Conodontenzonierung) und entspricht in etwa einer Dauer von 200+-10 Tausend Jahren. Der Event ist geprägt von markanten Faunenwechsel, die mit signifikanten Exkursionen im geochemischen und geophysikalischen Signal gekoppelt sind. Bisher durchgeführte Untersuchungen haben gezeigt, dass vor allem benthische Organismen aus tiefer marinen Ablagerungen auf die veränderten Umweltbedingungen reagiert haben. Neuere Erkenntnisse über diesen Event basieren vor allem auf Conodonten-Stratigraphie, sowie der Studie von stabilen Isotopen und Untersuchungen zur Magneto-Suszeptibilität von Sedimenten. Im Rahmen des vorgeschlagenen Projektes sollen Veränderungen in tropischen Korallen-Vergesellschaftungen (im speziellen von rugosen Korallen) während der Kacak-Krise untersucht werden. Die Lokalitäten der ausgewählten Gebiete (Karnische Alpen, Grazer Paläozoikum, Barrandium und Mähren) befanden sich zur damaligen Zeit, als Teile des Kontinentalschelfs von Nord-Gondwana, an unterschiedlichen Positionen in den niederen Breiten. Vor allem aus dem Mittel-Devon der Karnischen Alpen und des Grazer Paläozoikums sind fossile Kollektionen bekannt, die eine reiche und vielfältige rugose Korallenfauna beinhalten. Neben einer Menge an nicht bearbeitetem Material, welches sich in den Sammlungen wieder findet, gibt es unter den beschriebenen Korallen auch Arten, die Unstimmigkeiten hinsichtlich ihrer taxonomischen Stellung sowie der stratigraphischen Reichweite aufzeigen. Dazu kommt noch umfangreiches Material an rugosen Korallen aus Mähren, welches bis heute noch keiner detaillierten Bearbeitung unterzogen werden konnte. Ziel dieses Projektes ist es, einen Überblick über die rugosen Korallen geben zu können, die vom Kacak-Event betroffen waren. Dadurch sollen Fragen zur Resonanz von Klima empfindlichen Organismen auf sich verändernden Umweltbedingungen geklärt werden. Zusätzlich soll die Berechnung von Meerwasser Temperaturen aus unterschiedlich niederen Breiten und die Anwendung von geochemischen und geophysikalischen Methoden dazu beitragen, Ursachen die für den Kacak-Event verantwortlich waren, heraus zu finden. usw.

Raw data of physical oceanography during RV HEINCKE cruise HE669

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.
