title: Bacteria, meiofauna and macrofauna density and macrofauna biomass in the HAUSGARTEN area (Fram Strait) in 2014 (POLARSTERN cruise PS85)

description: During PS85 in 2014 bacteria density, meiofauna density, macrofauna density and macrofauna biomass was determined. For the bacterial density determination, sediment subsamples were taken with modified syringes (1.17 cm² cross-sectional area) from MUC recovered sediment cores and from benthic chambers. The first centimetre of each sample was stored in a 2 % filtered formalin solution at 4 °C. The acridine orange direct count (AODC) method (Hobbie et al., 1977) was used to stain bacteria in the subsamples and subsequently bacteria were counted with a microscope (Axioskop 50, Zeiss) under UV-light (CQ-HXP-120, LEj, Germany). For the determination of the meiofauna density and identification of meiofauna taxa, sediment subsamples were taken with modified syringes (3.14 cm² cross-sectional area) from MUC recovered sediment cores. The first centimetre of each sample was stored in borax buffered 4 % formaldehyde solution at 4 °C. The samples were sieved over a 1000 µm and 32 µm mesh. Both fractions were centrifuged three times in a colloidal silica solution (Ludox TM-50) with a density of 1.18 g/cm³ and stained with Rose 20 Bengal (Heip et al., 1985). Afterwards, the taxa were identified and counted. Foraminifera are not considered, as the extraction efficiency of Ludox for different groups of foraminifera is insufficient for a quantitative assessment of the group. Therefore, only metazoan meiofauna is recorded. After taking subsamples for bacteria and meiofauna densities, the remaining sediment from MUC recovered sediment cores and from the benthic chambers was used for macrofauna taxonomical identification, and density and biomass determination. For these macrofauna analyses only the 0-5 cm horizon from MUC sediment cores and the entire remaining sediment from the benthic chambers was used, sieved over a 500 µm mesh and stored in borax buffered 4 % formaldehyde and stained with Rose Bengal (Heip et al., 1985). Afterwards, macrofauna taxa were identified to the highest taxonomic level, counted and weighted (blotted wet weight).

title: Ex situ measured oxygen profiles from station PS85/470-3 (HG I) within the HAUSGARTEN area (Fram Strait) in 2014 (POLARSTERN cruise PS85)

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 PS80/180-2

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: Taxa specific meiofauna density in the HAUSGARTEN area (Fram Strait) in 2015 (POLARSTERN cruise PS93.2)

description: Values were originally given per 10 cm**2 (rounded to 1 decimal place) and were recalculated to m**2 by multiplying by 1000.During PS93.2 (in 2015) bacteria density, meiofauna density, macrofauna density and macrofauna biomass was determined.
