Cooling crusts create concomitant cryovolcanic cracks

ML Rudolph, M Manga, M Walker… - Geophysical Research …, 2022 - Wiley Online Library
The orbital and internal evolution of the ice‐covered ocean worlds orbiting Jupiter and
Saturn are coupled, leading to time‐varying thicknesses of their ice shells. As the ice …

A poro-damage phase field model for hydrofracturing of glacier crevasses

X Sun, R Duddu - Extreme Mechanics Letters, 2021 - Elsevier
Hydraulic fracture (or hydrofracture) can promote the propagation of meltwater-filled surface
crevasses in glaciers and, in some cases, lead to full-depth penetration that can enhance …

[HTML][HTML] Recrystallization of ice enhances the creep and vulnerability to fracture of ice shelves

M Ranganathan, B Minchew, CR Meyer… - Earth and Planetary …, 2021 - Elsevier
The initiation of fractures and fast flow in floating regions of Antarctica have the potential to
destabilize large regions of the grounded ice sheet, leading to rapid sea-level rise. While …

Ocean coupling limits rupture velocity of fastest observed ice shelf rift propagation event

SD Olinger, BP Lipovsky, MA Denolle - AGU Advances, 2024 - Wiley Online Library
The Antarctic ice sheet is buttressed by floating ice shelves that calve icebergs along large
fractures called rifts. Despite the significant influence exerted by rifting on ice shelf geometry …

E Magnússon, F Pálsson, MT Gudmundsson… - The …, 2021 - tc.copernicus.org
We present repeated radio-echo sounding (RES, 5 MHz) on a profile grid over the eastern
Skaftá cauldron (ESC) in Vatnajökull ice cap, Iceland. The ESC is a∼ 3 km wide and 50 …

Elastic stress coupling between supraglacial lakes

LA Stevens, SB Das, MD Behn… - Journal of …, 2024 - Wiley Online Library
Supraglacial lakes have been observed to drain within hours of each other, leading to the
