The instantaneous impact of calving and thinning on the Larsen C Ice Shelf

T Mitcham, GH Gudmundsson, JL Bamber - The Cryosphere, 2022 - tc.copernicus.org
The Antarctic Peninsula has seen rapid and widespread changes in the extent of its ice
shelves in recent decades, including the collapse of the Larsen A and B ice shelves in 1995 …

Effects of calving and submarine melting on steady states and stability of buttressed marine ice sheets

M Haseloff, OV Sergienko - Journal of Glaciology, 2022 - cambridge.org
Mass loss from ice shelves is a strong control on grounding-line dynamics. Here we
investigate how calving and submarine melt parameterizations affect steady-state grounding …

Evaluation of four calving laws for Antarctic ice shelves

JA Wilner, M Morlighem, G Cheng - The Cryosphere Discussions, 2023 - tc.copernicus.org
Many floating ice shelves in Antarctica buttress the ice streams feeding them, thereby
reducing the discharge of icebergs into the ocean. The rate at which ice shelves calve …

[HTML][HTML] Shear-margin melting causes stronger transient ice discharge than ice-stream melting in idealized simulations

J Feldmann, R Reese, R Winkelmann… - The …, 2022 - tc.copernicus.org
Basal ice-shelf melting is the key driver of Antarctica's increasing sea-level contribution. In
diminishing the buttressing force of the ice shelves that fringe the ice sheet, the melting …

Probabilistic projections of the Amery Ice Shelf catchment, Antarctica, under conditions of high ice-shelf basal melt

S Jantre, MJ Hoffman, NM Urban, T Hillebrand… - The …, 2024 - tc.copernicus.org
Antarctica's Lambert Glacier drains about one-sixth of the ice from the East Antarctic Ice
Sheet and is considered stable due to the strong buttressing provided by the Amery Ice …

Subglacial discharge effects on basal melting of a rotating, idealized ice shelf

I Vaňková, X Asay-Davis, C Branecky Begeman… - The …, 2025 - tc.copernicus.org
When subglacial meltwater is discharged into the ocean at the grounding line, it acts as a
source of buoyancy, enhancing flow speeds along the ice base that result in higher basal …

Timescales of outlet-glacier flow with negligible basal friction: theory, observations and modeling

J Feldmann, A Levermann - The Cryosphere Discussions, 2022 - tc.copernicus.org
The timescales of the flow and retreat of Greenland's and Antarctica's outlet glaciers and
their potential instabilities are arguably the largest uncertainty in future sea-level projections …
