Raw data of physical oceanography during RV HEINCKE cruise HE689

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), conductivity (SBE4) and 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 (Other version).

Physical oceanography during RV HEINCKE cruise HE689

Conductivity-temperature-depth profiles were measured using a Seabird SBE 911plus CTD during RV HEINCKE cruise HE689. 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.

Seawater carbonate chemistry and behavioural trait expression of polar invertebrates

Here, we examine the ecosystem ramifications of changes in sediment-dwelling invertebrate bioturbation behaviour—a key process mediating nutrient cycling—associated with nearfuture environmental conditions (+ 1.5 °C, 550 ppm [pCO2]) for species from polar regions experiencing rapid rates of climate change. This dataset is included in the OA-ICC data compilation maintained in the framework of the IAEA Ocean Acidification International Coordination Centre (see https://oa-icc.ipsl.fr). Original data were downloaded from Polar Data Centre (see Source) by the OA-ICC data curator. In order to allow full comparability with other ocean acidification data sets, the R package seacarb (Gattuso et al, 2024) was used to compute a complete and consistent set of carbonate system variables, as described by Nisumaa et al. (2010). In this dataset the original values were archived in addition with the recalculated parameters (see related PI). The date of carbonate chemistry calculation by seacarb is 2024-07-11.

Ernährungsökologische Nische und Habitatstruktur in benthischen Nahrungsnetzen

In Laborversuchen sollen qualitative und quantitative Aspekte der Interaktion von dominierenden Organismen benthischer Nahrungsnetze vergleichend marin-limnisch untersucht werden. Zentrale Aufgabenstellungen sind: a) Identifikation der potentiellen und der im Einzelfall realisierten ernährungsökologischen Nische dominierender Makroinvertebraten mit konventionellen Methoden sowie über die quantitative Bestimmung extrazellulärer Verdauungsenzyme. b) Quantitative Untersuchung von Epiphyten und Makrophyten in ihrer Funktion als Nahrung bzw. Habitatbildner bei unterschiedlicher Dichte und Zusammensetzung der Makroinvertebraten. c) Untersuchung der Populationsdynamik von Räuber-Beute/Grazer-Algen -Systemen in Abhängigkeit vom Nahrungsangebot und von Fraßrefugien unter Zugrundelegung von Gradienten experimenteller Manipulation. d) Modifizierender Einfluss höherer (Fische) bzw. niedrigerer (Bakterien und Protozoen) trophischer Ebenen auf die zuvor festgestellten Interaktionen.
