Distribution of soil nitrogen and nitrogenase activity in the forefield of a High Arctic receding glacier

open access: yesAnnals of Glaciology, 2018
Glaciers retreating in response to climate warming are progressively exposing primary mineral substrates to surface conditions. As primary production is constrained by nitrogen (N) availability in these emerging ecosystems, improving our understanding of

Applied Glaciology—the Utilization of Ice and Snow in Arctic Operations [PDF]

open access: yesJournal of Glaciology, 1960
AbstractIn addition to field observations and quantitative analyses of natural phenomena, an opportunity exists for the application of glaciological knowledge. Major problems preventing the widespread use of ice and snow as structural materials are related to processing methods, properties of ice and snow, and deterioration during the melt season ...

Environmental factors influencing diatom communities in Antarctic cryoconite holes

open access: yesEnvironmental Research Letters, 2013
Cryoconite holes are ice-bound habitats that can act as refuges for aquatic and terrestrial microorganisms on glacier surfaces. In the McMurdo Dry Valleys of Antarctica, these holes are often capped by an ice lid that prevents the exchange of material ...

Fifty years of meteo-glaciological change in Toll Glacier, Bennett Island, De Long Islands, Siberian Arctic

open access: yesPolar Science, 2014
AbstractRapid environmental change has been observed in the De Long Islands, Siberian Arctic, where warming has extensively occurred over the area. To quantitatively evaluate glaciological changes since the 1980s, the climate, mass balance, and the equilibrium line altitude (ELA) of Toll Glacier on Bennett Island were analyzed.

Drivers of Atmosphere-Ocean CO2 Flux in Northern Norwegian Fjords

open access: yesFrontiers in Marine Science, 2021
High-latitude fjords and continental shelves are shown to be sinks for atmospheric CO2, yet large spatial-temporal variability and poor regional coverage of sea-air CO2 flux data, especially from fjord systems, makes it difficult to scale our knowledge ...

Opportunities for geomorphological and glaciological research from the Arctic-wide high resolution ArcticDEM

open access: yes, 2022
The ArcticDEM presents an interesting opportunity for research. By uniting knowledge and methods from geomorphometry and glaciology, this vast data source can help reconstructing features such as eskers, which are found in beds of paleo-ice sheets. This in turn can contribute to a deeper understanding and more accurate models of glacier dynamics. Using

Aldegondabreen glacier change since 1910 from structure-from-motion photogrammetry of archived terrestrial and aerial photographs: utility of a historic archive to obtain century-scale Svalbard glacier mass losses

open access: yesJournal of Glaciology, 2021
Photogrammetric reconstructions of the Aldegondabreen glacier on Svalbard from 17 archival terrestrial oblique photographs taken in 1910 and 1911 reveal a past volume of 1373.7 ± 78.2 · 106 m3; almost five times greater than its volume in 2016 ...
