Basal crevasses in Larsen C Ice Shelf and implications for their global abundance [PDF]
The Cryosphere, 2012 Basal crevasses extend upwards from the base of ice bodies and can penetrate more than halfway through the ice column under conditions found commonly on ice shelves.

Variability in the vertical temperature profile within crevasses at an alpine glacier
Journal of Glaciology, 2023 Tasman Glacier, a temperate maritime glacier in the New Zealand Southern Alps, is rapidly receding. Climate warming is resulting in lengthening of the ablation season, meaning crevasses in the accumulation area are becoming exposed at the surface for ...

Detection of Surface Crevasses over Antarctic Ice Shelves Using SAR Imagery and Deep Learning Method
Remote Sensing, 2022 Crevasses are formed by glacier movement and the stresses within glacier ice. Knowledge of the crevasses’ distribution is critical for understanding the glacier and ice shelf stability. In this study, we propose an automated crevasse extraction framework

Firn aquifer water discharges into crevasses across Southeast Greenland
Journal of Glaciology, 2023 In Southeast Greenland, summer melt and high winter snowfall rates give rise to firn aquifers: vast stores of meltwater buried beneath the ice-sheet surface.

Effect of ice formation in crevasses to the temperature field in the cold layer of glacier
Лëд и снег, 2023 The work focuses on modeling the warming of a glacier due to heat release during the refreezing of meltwater in glacier crevasses (cryo-hydrologic warming).

Crevasse advection increases glacier calving
Journal of Glaciology, 2022 Iceberg calving, the process where icebergs detach from glaciers, remains poorly understood. Moreover, few parameterizations of the calving process can easily be integrated into numerical models to accurately capture observations, resulting in large ...

Mapping Antarctic crevasses and their evolution with deep learning applied to satellite radar imagery [PDF]
The Cryosphere, 2023 The fracturing of glaciers and ice shelves in Antarctica influences their dynamics and stability. Hence, data on the evolving distribution of crevasses are required to better understand the evolution of the ice sheet, though such data have traditionally ...

Journal of Glaciology, 2020 Hydrofracturing can enhance the depth to which crevasses propagate and, in some cases, allow full depth crevasse penetration and iceberg detachment.

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021 Crevasse is an important characteristic of ice shelf internal structure, and also an important index to measure the stability of ice shelf. This study aims to detect crevasses from ICESat-2 data and obtain three-dimensional features of the crevasse ...

Basal hydrofractures near sticky patches
Journal of Glaciology, 2023 Basal crevasses are macroscopic structural discontinuities at the base of ice sheets and glaciers that arise by fracture. Motivated by observations and by the mechanics of elastic fracture, we hypothesise that spatial variations in basal stress (in the ...
