Quantifying subglacial roughness and its link to glacial geomorphology and ice speed [PDF]

, 2013
The shape of subglacial bed topography, termed its roughness, is a recognised control on basal ice-flow. Although glaciologists have observed patterns of variations in ice speed over beds with different roughness values, the strength of this relationship

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.

Assessing the catastrophic break-up of Briksdalsbreen, Norway, associated with rapid climate change

, 2011
Recent research has raised concerns about the potential influence of rapid climate change on the stability of major ice sheets. The behaviour of glaciers is determined largely by the processes and conditions operating at their base.

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 ...

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.

Impacts of subglacial processes on underlying bedrock

, 2019
Historically, the field of glacial geology has put much focus on the processes within the subglacial environment, their effects on unconsolidated sediments and the landforms they produce.
