Firn air content changes on Antarctic ice shelves under three future warming scenarios [PDF]
The CryosphereThe Antarctic firn layer provides pore space in which an estimated 94 % to 96 % of the surface melt refreezes or is retained as liquid water. Future depletion of firn pore space by increased surface melt, densification and formation of low-permeability ...

Equilibrium Profile of Ice Shelves
Journal of Glaciology, 1979 Abstract Using expressions for ice-shelf creep derived by Weertman (1957) and Thomas (1973[b]) a general method is developed for calculating equilibrium thickness profiles, velocities, and strain-rates for any ice shelf. This is done first for an unconfined glacier tongue and the result agrees well with data for Erebus Glacier tongue (

Roughness of Ice Shelves Is Correlated With Basal Melt Rates
, 2021 Ice shelf collapse could trigger widespread retreat of marine‐based portions of the Antarctic ice sheet. However, little is known about the processes that control the stability of ice shelves.

Basal channels on ice shelves [PDF]
Journal of Geophysical Research F: Earth Surface, 2013 Recent surveys of floating ice shelves associated with Pine Island Glacier (Antarctica) and Petermann Glacier (Greenland) indicate that there are channels incised upward into their bottoms that may serve as the conduits of meltwater outflow from the sub‐ice‐shelf cavity.

Calving glaciers and ice shelves [PDF]
Advances in Physics: X, 2018 Calving, or the release of icebergs from glaciers and floating ice shelves, is an important process transferring mass into the world’s oceans. Calving glaciers and ice sheets make a large contribution to sea-level rise, but large uncertainty remains ...

Vulnerable Antarctic ice shelves [PDF]
Nature Climate Change, 2016 Standfirst: The decay of floating ice shelves around Antarctica speeds up ice flow from the continent and enhances sea-level rise. Now meltwater attributed to warm winds has been discovered on an East Antarctic ice shelf, suggesting greater vulnerability than previously thought.

Change in Antarctic ice shelf area from 2009 to 2019 [PDF]
The Cryosphere, 2023 Antarctic ice shelves provide buttressing support to the ice sheet, stabilising the flow of grounded ice and its contribution to global sea levels. Over the past 50 years, satellite observations have shown ice shelves collapse, thin, and retreat; however,

Ice-shelf ocean boundary layer dynamics from large-eddy simulations [PDF]
The Cryosphere, 2022 Small-scale turbulent flow below ice shelves is regionally isolated and difficult to measure and simulate. Yet these small-scale processes, which regulate heat and salt transfer between the ocean and ice shelves, can affect sea-level rise by altering ...

A stress-based poro-damage phase field model for hydrofracturing of creeping glaciers and ice shelves [PDF]
Engineering Fracture Mechanics, 2022 There is a need for computational models capable of predicting meltwater-assisted crevasse growth in glacial ice. Mass loss from glaciers and ice sheets is the largest contributor to sea-level rise and iceberg calving due to hydrofracture is one of the ...
