Total oxygen uptake rates measured during POLARSTERN cruise PS94 (TransArcII)...
Total oxygen uptake rates were assessed by conducting sediment core incubations. After MUC retrieval and sediment core preparation on deck, three cores were taken to a dark,... -
Chlorophyll pigments and total organic carbon measured during POLARSTERN crui...
Chlorophyll pigments:Subsamples of the top first cm of sediment were obtained using cut-off plastic syringes. Samples for chlorophyll pigment analyses were stored dark and... -
Microbial cell numbers measured during POLARSTERN cruise PS94 (TransArcII) to...
For the determination of prokaryotic cell numbers, 1 cm³ sediment was fixed with sterile filtered formalin/seawater at a final concentration of 2% and stored at 4°C until... -
Diffusive oxygen uptake rates measured during POLARSTERN cruise PS94 (TransAr...
We assessed diffusive oxygen uptake rates by measuring ex situ porewater oxygen microprofiles. Sediment cores were placed in a water bath and a stirring device was implemented... -
Abundance of Prokaryotes in deep-sea sediments analyzed by CARD-FISH
We fixed 0.5 g aliquots of sediment with a 4% formaldehyde solution for 2-4 h, washed the fixed sediments three times with 1x phosphate-buffered saline (PBS), before storing... -
Biogeochemical characterization of pennate diatom and Melosira arctica ice al...
Sea-ice diatoms are known to accumulate in large aggregates in and under the sea ice including melt ponds. In the Arctic, they can contribute substantially to particle export... -
Benthic biogeochemical parameters measured during Polarstern expedition PS94 ...
During the RV Polarstern expedition PS94, we gathered sediment samples in the Barents Sea and the central Arctic Ocean by deploying both a multiple corer (MUC) and a giant... -
Solar radiation over and under sea ice and photographic quantification of Ice...
The ice cover of the Arctic Ocean has been changing dramatically in the last decades and the consequences for the sea-ice associated ecosystem remain difficult to assess. Algal... -
Photosynthetic production in the Central Arctic during POLARSTERN cruise ARK-...
The ice-covered Central Arctic Ocean is characterized by low primary productivity due to light and nutrient limitations. It has been speculated that the recent reduction in ice... -
Response of Arctic benthic bacterial deep-sea communities to different detrit...
In a multidisciplinary ex situ experiment, benthic bacterial deep-sea communities from 2,500 m water depth at the Long-Term Ecological Research Observatory HAUSGARTEN... -
The effect of hydrostatic de- and re-compression events on deep-sea bacterial...
This work focuses on the effect of decompression on bacterial communities from deep-sea surface sediments. We evaluated the effects of slow and fast decompression (within hours... -
Bacterial and eukaryotic operational taxonomic units (OTU) in sea ice, water ...
We aimed to explore the community composition and turnover of eukaryotic and bacterial microorganisms associated with ice-associated and sinking algal aggregates, as well as... -

Chlorophyll pigment concentrations of Elpidia heckeri gut content collected f...
Chlorophyll pigments were extracted in acetone (90%), after addition of glass beads and grinding of each sample in a cell mill (Boetius and Damm 1998,... -
Sediment phaeopigment concentrations from the Laptev Sea (Arctic Ocean) durin...
Sampling was conducted with a TV-guided multiple corer (MUC), in order to retrieve undisturbed sediment cores. Upon retrieval of the MUC, the overlying water was carefully... -
Diffusive oxygen uptake from the Laptev Sea (Arctic Ocean) during POLARSTERN ...
In this study, we measured a range of biogeochemical parameters down the Laptev Sea continental slope, from around 50 to 3400 m water depth. These included chlorophyll pigments,... -
TV-MUC video compilation from the Laptev Sea continental slope (Arctic Ocean)...
Video images were obtained with a TV-guided multiple corer (MUC) from a transect down the Laptev Sea continental slope, covering water depths between 60 and 3000 m. Video images...
