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... -

Molecular formula calculation for all samples was performed using an in-house Matlab (2010) routine that searches, with an error of < 0.5 ppm, for all potential combinations... -
Total dissolved organic carbon and total dissolved nitrogen in sediment pore ...
During the RV Polarstern cruise ARK-XXVII/3 to the Arctic Ocean in summer 2012, when sea ice declined to a record minimum bottom, water and sediment pore water samples were... -
