title: Ex situ measured oxygen profiles from station PS93/050-19 (HG IV) within the HAUSGARTEN area (Fram Strait) in 2015 (POLARSTERN cruise PS93.2)

description: During PS85 (in 2014) and PS93.2 (in 2015) sediment cores were recovered by a Multiple corer. Sediment cores were stored at in situ temperature of -0.75°C and used to measure oxygen profiles across the sediment-water interface with needle type optodes (diameter: 50µm, Pyro Science). By using the profiles, the diffusive oxygen uptake was calculated via the decrease in the oxygen concentration in the Diffusive Boundary Layer (DBL). For a further description of the calculation, please check the related publication.

title: Biochemical investigation of multicorer sediment profile PS99/050-2

description: To detect and track the impact of large-scale environmental changes in a the transition zone between the northern North Atlantic and the central Arctic Ocean, and to determine experimentally the factors controlling deep-sea biodiversity, the Alfred- Wegener-Institute for Polar and Marine Research (AWI) established the deep-sea long-term observatory HAUSGARTEN, which constitutes the first, and until now only open-ocean long-term station in a polar region. Virtually undisturbed sediment samples have been taken using a video-guided multiple corer (MUC) at 13 HAUSGARTEN stations along a bathymetric (1,000 - 4,000 m water depth) and a latitudinal transect in 2,500 m water depth as well as two stations at 230 and 1,200 m water depth within the framework of the KONGHAU project. Various biogenic sediment compounds were analyzed to estimate the input of organic matter from phytodetritus sedimentation, benthic activities (e.g. bacterial exoenzymatic activity), and the total biomass of the smallest sediment-inhabiting organisms (size range: bacteria to meiofauna).

title: Counts and shell weights of planktonic foraminifera in the Fram Strait from mooring FEVI30 at AWI HAUSGARTEN

description: Absolute counts and average shell weights of distinct species of planktonic at the central station of the LTER (Long-Term Ecological Research) HAUSGARTEN observatory in the Fram Strait at two depths intervals (213 m, 2319 m) from a one-year time period (24.06.2014 to 15.07.2015). Samples were collected with two modified automatic Kiel sediment traps installed in a bottom-tethered long-term mooring. Foraminifera shells from a split of each sample, representing 15-30 days within the whole sampling period (20 samples in total), were picked from the wet samples in 2020-2021. The counts of planktonic foraminifera represent the number of shells in the indicated split (i.e. not in the total sample). Species determination was done based on Brummer and Kucera (2022, https://doi.org/10.5194/jm-41-29-2022). Weight measurements were conducted on bulk samples (per species and sample) using a Sartorius SE2 ultra-micro balance (nominal resolution of 0.1 µg), divided by the number of shells in the sample to get the average weight per shell. Measurements were either conducted on the whole sample (per species), or, in samples containing more than 200 foraminifera shells, on at maximum 200 shells representing the variety of shells present in the samples. Counts and measurements were conducted to calculate mass fluxes of planktonic foraminifera at different depth intervals throughout a whole seasonal cycle.

title: Shell sizes of planktonic foraminifera in the Fram Strait from mooring FEVI30 at AWI HAUSGARTEN

description: Individual, species-specific shell sizes of planktonic foraminifera from the central station of the LTER (Long-Term Ecological Research) HAUSGARTEN observatory in the Fram Strait at two depths intervals (213 m, 2319 m) from a one-year time period (24.06.2014 to 15.07.2015). Samples were collected with two modified automatic Kiel sediment traps installed in a bottom-tethered long-term mooring. Species determination was done based on Brummer and Kucera (2022, https://doi.org/10.5194/jm-41-29-2022). Individual shell sizes of all shells present in 1/8 or 1/16 split of each sample were measured at the umbilical view using a KEYENCE VHX-6000 digital microscope (shell counts in relation to the split of the samples are available separately). Measurements were conducted in 2020-2021.Size measurements were conducted to analyse the evolution of species-specific planktonic foraminifera shell size throughout a whole seasonal cycle, and to compare average sizes at different depth intervals.

title: Carbonate (CaCO3) and particulate organic carbon (POC) fluxes in the Fram Strait from mooring FEVI30 at AWI HAUSGARTEN

description: Carbonate (CaCO3) and particulate organic carbon (POC) fluxes at the central station of the LTER (Long-Term Ecological Research) HAUSGARTEN observatory in the Fram Strait at two depths intervals (213 m, 2319 m) from a one-year time period (24.06.2014 to 15.07.2015). Samples were collected with two modified automatic Kiel sediment traps installed in a bottom-tethered long-term mooring. The CaCO3 flux is given as total flux and as flux excluding aragonite, which was determined using the mass flux from pteropods. The three parameters were determined as described in Bauerfeind et al. (2009, https://doi.org/10.1016/j.dsr.2009.04.011) shortly after sample retrieval.The carbonate and POC fluxes were determined for comparison with mass fluxes of planktonic foraminifera and set them into relation to each other.
