Large-scale Modelling of Subglacial Hydrology [PDF]

, 2018
Subglacial hydrology is a key component in ice sheet dynamics and controls the sliding of ice sheets. Modelling the integrated system between ice dynamics and subglacial hydrology is essential for understanding current changes in the system and ...

Eurasian ice-sheet dynamics and sensitivity to subglacial hydrology [PDF]

, 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

Topography and accumulation rate as controls of asynchronous surging behaviour in the eastern and western branches of the Western Kunlun Glacier, Northwestern Tibetan Plateau

International Journal of Digital Earth
The western Kunlun main peak region is among the areas in High Mountain Asia where surge-type glaciers are highly concentrated. Here, we analyse the surging characteristics of the eastern and western branches of the Western Kunlun Glacier and the factors

Glacial erosion: status and outlook

Annals of Glaciology, 2019
Glacier-erosion rates range across orders of magnitude, and much of this variation cannot be attributed to basal sliding rates. Subglacial till acts as lubricating ‘fault gouge’ or ‘sawdust’, and must be removed for rapid subglacial bedrock erosion. Such

Dendritic subglacial drainage systems in cold glaciers formed by cut-and-closure processes

, 2014
The routing and storage of meltwater and the configuration of drainage systems in glaciers exert a profound influence on glacier behaviour. However, little is known about the hydrological systems of cold glaciers, which form a significant proportion of the total glacier population in the climate sensitive region of the High Arctic.

A lee-side cavity fill diamicton under the Durance valley glacier: Insights from hoodoos of the Remollon Arch, Southern French Alps

Sedimentologika
Deep and narrow gullies dissecting reliefs of the Southern French Alps are filled with 10's to 100's meters thick accumulation of unsorted, boulder-rich muddy material (i.e., diamicton) left behind by glaciers that repeatedly covered the region during ...

Simulating seasonal evolution of subglacial hydrology at a surging glacier in the Karakoram

Journal of Glaciology
Glacier motion, retreat and glacier hazards such as surges and glacial lake outburst floods (GLOFs) are likely underpinned by subglacial hydrology. Recent advances in subglacial hydrological modeling allow us to shed light on subglacial processes that ...

Reconstructing the glacial history of Upgang, North Yorkshire: a North Sea ice lobe readvance during the termination of the last glacial maximum? [PDF]

, 2007
Around Great Britain at the end of the Last Glacial Maximum (LGM) there is evidence for a number of glacial readvances, specifically in the Irish Sea Basin and Eastern Scotland.

Transient glacier dynamics and subglacial hydro-mechanical processes

, 2023
The Cryosphere, encompassing elements like sea ice, permafrost, snow, glaciers, and ice sheets, faces a grave threat from ongoing climate change and can significantly impact ecosystems, human lives, and livelihoods. Understanding their dynamics is essential to predict their future and inform mitigation strategies.

Ice mass discharge through the Antarctic subglacial hydrographic network as a trigger for cryoseismicity

Journal of Glaciology
We analyse seismic time series collected during experimental campaigns in the area of the David Glacier, Victoria Land, Antarctica, between 2003 and 2016.
