Dissolved organic carbon and total dissolved nitrogen in sediment porewater a...
This data shows concentrations of dissolved organic carbon and total dissolved nitrogen measured in overlying bottom water and sediment porewaters via catalytic oxidation at... -
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... -
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,... -
Extracellular enzymatic activity from the Arctic Ocean during POLARSTERN crui...
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... -

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... -
Dissolved organic carbon in sediments of the central Arctic Ocean collected d...
Marine organic matter (OM) sinks from surface waters to the seafloor via the biological pump. Benthic communities, which use this sedimented OM as energy and carbon source,... -
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... -
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... -
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... -
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... -
