Denitrification and anammox activity in Arctic marine sediments
We measured rates of N2 production through anaerobic NH4+ oxidation with NO2−(anammox) and denitrification in permanently cold (from −1.7°C to 4°C) sediments off the east and west coasts of…

Inorganic carbon transport during sea ice growth and decay : A carbon pump in polar seas
[1] During sea ice formation in polar areas, brine rejection increases the density in the underlying water column and thereby contributes to the formation of deep and intermediate water masses in the…

Benthic mineralization and exchange in Arctic sediments (Svalbard, Norway)
By means of benthic landers, sediment core incubations and the whole core squeezing (WCS) technique, benthic exchange and mineralization rates were investigated in 4 different fjords of Arctic Norway…

Oxygen dynamics in the rhizosphere of Zostera marina: A two‐dimensional planar optode study
TLDR
The oxygen dynamics in the rhizosphere of Zostera marina was studied by use of planar optodes and oxic sediment volume around the roots increased linearly with irradiance in the interval of 0‐250 mmol photons m 22.

Benthic diatoms of a high Arctic fjord (Young Sound, NE Greenland): importance for ecosystem primary production
Patches of benthic diatoms covered 23 to 73% of the sediment area at water depths down to 30 m of a high Arctic fjord system (Young Sound, NE Greenland). Mapping of the in situ chlorophyll (chl a)…

High rates of microbial carbon turnover in sediments in the deepest oceanic trench on Earth
Microbes regulate the decomposition of organic matter in marine sediments. Measurements at the deepest oceanic site on Earth reveal high rates of microbial activity, potentially fuelled by the…
