The nitrogen cycle in cryoconites: naturally occurring nitrification‐denitrification granules on a glacier
Cryoconites are microbial aggregates commonly found on glacier surfaces where they tend
to take spherical, granular forms. While it has been postulated that the microbes in …

Glacial water: a dynamic microbial medium
Microbial communities and nutrient dynamics in glaciers and ice sheets continuously
change as the hydrological conditions within and on the ice change. Glaciers and ice sheets …

Microbial dynamics in a High Arctic glacier forefield: a combined field, laboratory, and modelling approach
Modelling the development of soils in glacier forefields is necessary in order to assess how
microbial and geochemical processes interact and shape soil development in response to …

Large cryoconite aggregates on a Svalbard glacier support a diverse microbial community including ammonia-oxidizing archaea
The aggregation of surface debris particles on melting glaciers into larger units (cryoconite)
provides microenvironments for various microorganisms and metabolic processes. Here we …

Increased above-and belowground plant input can both trigger microbial nitrogen mining in subarctic tundra soils
Low nitrogen (N) availability in the Arctic and Subarctic constrains plant productivity,
resulting in low litter inputs to soil. Increased N availability and litter inputs as a result of …

Impact of Sea Ice Melting on Summer Air-Sea CO2 Exchange in the East Siberian Sea
The role of sea ice melting on the air-sea CO2 flux was investigated at two ice camps in the
East Siberian Sea of the Arctic Ocean. On average, sea ice samples from the two ice camps …

Diurnal cycle of iodine, bromine, and mercury concentrations in Svalbard surface snow
Sunlit snow is highly photochemically active and plays a key role in the exchange of gas
phase species between the cryosphere and the atmosphere. Here, we investigate the …
