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... -

Net Primary Production was measured using the 14C uptake method with minor modifications. Melted sea ice samples were spiked with 0.1µCi ml-1 of 14C labelled sodium bicarbonate... -
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,... -
Prokaryotic cell abundance and biomass measured during Maria S. Merian cruise...
Prokaryotic cell abundances and biomass were determined in deep-sea sediment samples collected at the deep-sea LTER HAUSGARTEN, located in the Fram Strait. Sampling was... -
CARD-FISH counts of the water column and sediment at HAUSGARTEN, Fram Strait
We determined the concentrations of different types of bacteria via Catalysed reporter deposition-fluorescence in situ hybridization (CARD-FISH) at different depths of the water... -

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... -
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... -
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... -

Contribution of formulae and elemental ratios of solid phase extracted dissol...
Molecular formulae were additionally associated with different molecular categories because less than 6% of the DOM has been identified on a molecular level.Molecular categories... -
Molecular formulae with CHONSP elements from POLARSTERN cruise ARK-XXVII/3 (I...
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... -
