Progress toward globally complete frontal ablation estimates of marine-terminating glaciers

open access: yesAnnals of Glaciology, 2022
Knowledge of frontal ablation from marine-terminating glaciers (i.e., mass lost at the calving face) is critical for constraining glacier mass balance, improving projections of mass change, and identifying the processes that govern frontal mass loss ...

Modelling last glacial cycle ice dynamics in the Alps [PDF]

open access: yesThe Cryosphere, 2018
The European Alps, the cradle of pioneering glacial studies, are one of the regions where geological markers of past glaciations are most abundant and well-studied.

Using a Web Map Service to map Little Ice Age glacier extents at regional scales

open access: yesAnnals of Glaciology, 2023
Extending the record of glacier area changes into the past improves our understanding of climate change impacts. Although analogue maps showing historic glacier extents are abundant, digital outlines from before the satellite era are sparse as the ...

Basal seismicity of the Northeast Greenland Ice Stream

open access: yesJournal of Glaciology, 2020
Seismic studies of glaciers yield insights into spatio-temporal processes within and beneath glaciers on scales relevant to flow and deformation of the ice.

Eurasian ice-sheet dynamics and sensitivity to subglacial hydrology

open access: yesJournal of Glaciology, 2017
Ice-stream dynamics are strongly controlled by processes taking place at the ice/bed interface where subglacial water both lubricates the base and saturates any existing, underlying sediment. Large parts of the former Eurasian ice sheet were underlain by

Dark ice dynamics of the south-west Greenland Ice Sheet [PDF]

open access: yesThe Cryosphere, 2017
Runoff from the Greenland Ice Sheet (GrIS) has increased in recent years due largely to changes in atmospheric circulation and atmospheric warming. Albedo reductions resulting from these changes have amplified surface melting.

Surge-type glaciers in Kalaallit Nunaat (Greenland): distribution, temporal patterns and climatic controls

open access: yesJournal of Glaciology, 2023
We present the first systematic inventory of surge-type glaciers for the whole of Greenland compiled from published datasets and multitemporal satellite images and digital elevation models.

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 ...
