Rift propagation signals the last act of the Thwaites Eastern Ice Shelf despite low basal melt rates
Journal of GlaciologyRift propagation, rather than basal melt, drives the destabilization and disintegration of the Thwaites Eastern Ice Shelf. Since 2016, rifts have episodically advanced throughout the central ice-shelf area, with rapid propagation events occurring during ...

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 10, October 2026.Abstract Iceberg calving driven by crevasse propagation is an important source of ice loss from the Greenland and Antarctic ice sheets. However, simulating crevasse growth and interaction in 3D, spanning meters to kilometers length scales, remains computationally challenging for high‐fidelity models based on nonlocal continuum damage mechanics and ...

Theoretical stability of ice shelf basal crevasses with a vertical temperature profile
Journal of GlaciologyBasal crevasses threaten the stability of ice shelves through the potential to form rifts and calve icebergs. Furthermore, it is important to determine the dependence of crevasse stability on temperature due to large vertical temperature variations on ...

Quantifying supraglacial meltwater pathways in the Paakitsoq region, West Greenland
Journal of Glaciology, 2017 Increased summer ice velocities on the Greenland ice sheet are driven by meltwater input to the subglacial environment. However, spatial patterns of surface input and partitioning of meltwater between different pathways to the base remain poorly ...

Alluvial ridge morphology on avulsing rivers
Sedimentology, Volume 73, Issue 6, Page 2311-2337, October 2026.ABSTRACT Alluvial ridges are built by preferential channel‐belt deposition and control river avulsions, yet a systematic analysis of their morphology has been missing. To address this gap, we analyse a globally distributed dataset of 8970 alluvial ridge flanks on 14 different rivers.

Journal of Glaciology, 2018 We investigate the appropriateness of calving or crevasse models from the literature using linear elastic fracture mechanics (LEFM). To this end, we compare LEFM model-predicted stress intensity factors (SIFs) against numerically computed SIFs using the ...

Probabilistic Multi-Robot Task Scheduling for the Antarctic Environments with Crevasses
This paper deals with the problem of multi-robot task scheduling in the Antarctic environments with crevasses. Because the crevasses may cause hazardous situations when robots are operated in the Antarctic environments, robot navigation should be planned

Observed meltwater-induced flexure and fracture at a doline on George VI Ice Shelf, Antarctica
Journal of GlaciologyGlobal Navigation Satellite System (GNSS) observations and ground-based timelapse photography obtained over the record-high 2019/2020 melt season are combined to characterise the flexure and fracture behaviour of a previously formed doline on George VI ...

Annals of Glaciology, 2019 GPS measurements of tidal modulation of ice flow and seismicity within the grounding zone of Beardmore Glacier show that tidally induced fluctuations of horizontal flow are largest near the grounding line and decrease downstream.
