Impacts of Temperature‐ and Stress‐Dependent Rheology on Ice‐Shelf‐Front Bending

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 3, March 2026.
Abstract Classical treatments of ice‐shelf bending suggest that shelf fronts should bend downwards, due to the distribution of hydrostatic water pressure at the front. However, LiDAR data show several instances of upward‐bending ice‐shelf fronts. While this phenomenon has often been attributed to a buoyant force from a submerged ice bench, recent work ...

Accumulation Studies at a High Elevation Glacier Site in Central Karakoram

Advances in Meteorology, 2014
The precipitation conditions in central Karakoram are investigated on the basis of snow samples from high elevated snow pits at Urdok glacier from 2006 and the analysis of atmospheric transport trajectories in combination with the general, large scale ...

Antarctic subglacial hydrology: current knowledge and future challenges [PDF]

, 2014
Flood-carved landforms across the deglaciated terrain of Victoria Land, East Antarctica, provide convincing geomorphological evidence for the existence of subglacial drainage networks beneath the Antarctic ice sheet, and motivate research into the ...

Post‐Collapse Ice Cliff Backwasting at the Marmolada Glacier Observed by Terrestrial Radar Interferometry

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 3, March 2026.
Abstract The unexpected collapse of the Marmolada Glacier in the Italian Alps on 3 July 2022, caused 11 fatalities and emphasized the need for a deeper understanding of unstable glaciers. In response, we initiated a radar monitoring campaign to assess the stability of the remaining ice cliff and obtained a near‐continuous data set of displacement at ...

Rapid Seismic and Infrasound Assessment of Large Landslides: A Case Study From Denali National Park and Preserve (Alaska)

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 3, March 2026.
Abstract Large, rapid landslides are a global hazard that can occur in remote, mountainous areas. Eyewitness reports of landslides and satellite imagery can often be limited or delayed, particularly during inclement weather. However, landslide‐generated seismic and infrasound (low‐frequency atmospheric sound) waves can be remotely detected in near real‐

Resolving the internal and basal geometry of ice masses using imaging phase-sensitive radar

Journal of Glaciology, 2018
The phase-sensitive radio-echo sounder (pRES) is a powerful new instrument that can measure the depth of internal layers and the glacier bed to millimetre accuracy.

Effect of the Flow‐Law Exponent on Ice‐Stream Sensitivity to Melt

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 3, March 2026.
Abstract The flow‐law exponent, n, defines the relationship between stress and strain rate in ice. Growing evidence suggests that n ranges from 1 to 4 rather than taking the single, commonly used value of 3. Larger n implies that ice‐flow speeds are more sensitive to changes in stress.

Geochronology of the Whittlesey sedimentary succession, eastern England: The ‘Pompeii’ of the British late Middle Pleistocene to Holocene record

Journal of Quaternary Science, Volume 41, Issue 2, Page 260-287, February 2026.
ABSTRACT The sedimentary succession at Whittlesey preserves a unique British late Middle Pleistocene to Holocene record back to a time equivalent to at least marine oxygen isotope stage 8 (ca. 250 ka). This study builds on previously published sedimentology, geochronology and palaeoecology results to establish 20 sedimentary facies associations, with ...

The Role of Basal Roughness and Assemblage Grain‐Size Distribution in Shaping Granular Rheology and Basal‐Force Signals

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 2, February 2026.
Abstract We present idealized 3‐D discrete element simulations exploring how varying boundary roughness and grain‐size distribution affect bulk granular‐rheology and basal‐force distributions. Boundary roughness has a direct control on the internal static friction coefficient.
