Raw data of physical oceanography during RV HEINCKE cruise HE659

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.

Physical oceanography during RV HEINCKE cruise HE658

Conductivity-temperature-depth profiles were measured using a Seabird SBE 911plus CTD during RV HEINCKE cruise HE658. 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.

Untersuchungen zur qualitativen und quantitativen Bedeutung mixotropher Protisten in ufernahen Sedimenten

Im Rahmen der hier vorgeschlagenen Studie sollen erstmalig das Vorkommen und die ökologische Bedeutung mixotropher Protisten in küsten- bzw. ufernahen Sedimenten aquatischer Lebensräume untersucht werden. Im Konzept des mikrobiellen Nahrungsnetzes, eines integralen Teils planktischer Nahrungsnetze, das durch den Fraßdruck kleiner Protisten auf Bakterien geprägt ist, spielen mixotrophe Einzeller eine entscheidende Rolle. Durch ihre Fähigkeit zur Kombination der oxygenen Photosynthese wirken sie im System sowohl auf der Ebene der Primärproduzenten als auch auf der der Konsumenten partikulären organischen Materials. Ausmaß und relative Bedeutung der unterschiedlichen Ernährungsmodi unterlagen sowohl auf Organismen- als auch auf Lebensraumebene sehr großen Schwankungen. Im Vergleich zu pelagischen Lebensräumen gibt es noch große Lücken im Wissensstand zur ökologischen Bedeutung benthischer Protisten. Zwar ist die Gemeinschaft des Mikrophytobenthos sowohl hinsichtlich der von ihr gestellten Biomasse als auch hinsichtlich ihrer Photosyntheseleistung sehr gut untersucht, der Großteil der Arbeiten an benthischen 'Protozoen' beschränkt sich dagegen auf Studien, die wenig zu ihrer Funktion im Lebensraum sagen. Zum Potential für Mixotrophie benthischer Einzeller gibt es bisher keine Studien. Die enge taxonomische Verwandschaft zwischen Vertretern der benthischen und der pelagischen Einzeller legt die Vermutung nahe, dass in den euphotischen Bereichen mariner und limnischer Sedimente mixotrophe Protisten vorkommen und einen erheblichen Beitrag sowohl an der Produktion als auch am Konsum organischen Materials haben. Das hier vorgestellte Projekt dient dem Ziel, das Vorkommen benthischer Mixotrophre zu verifizieren, ihre Bedeutung für die Lebensgemeinschaft zu ermitteln und die Auswirkungen verschiedener abiotischer und biotischer Faktoren (Licht, Temperatur, Nährstoff- bzw. Nahrungsangebot) für die Ausbildung oder Dominanz der unterschiedlichen Ernährungsmodi zu beschreiben
