Marine ice sheet instability and ice shelf buttressing of the Minch Ice Stream, northwest Scotland [PDF]

The Cryosphere, 2018
Uncertainties in future sea level projections are dominated by our limited understanding of the dynamical processes that control instabilities of marine ice sheets. The last deglaciation of the British–Irish Ice Sheet offers a valuable example to examine

The impact of the North American glacial topography on the evolution of the Eurasian ice sheet over the last glacial cycle [PDF]

Climate of the Past, 2016
Modeling studies have shown that the continental-scale ice sheets in North America and Eurasia in the last glacial cycle had a large influence on the atmospheric circulation and thus yielded a climate distinctly different from the present.

Pliocene Ice Sheet Modelling Intercomparison Project (PLISMIP) – experimental design [PDF]

Geoscientific Model Development, 2012
During the mid-Pliocene warm period (3.264 to 3.025 million years ago), global mean temperature was similar to that predicted for the next century and atmospheric carbon dioxide concentrations were slightly higher than today.

GREB-ISM v1.0: A coupled ice sheet model for the Globally Resolved Energy Balance model for global simulations on timescales of 100 kyr [PDF]

Geoscientific Model Development, 2022
We introduce a newly developed global ice sheet model coupled to the Globally Resolved Energy Balance (GREB) climate model for the simulation of global ice sheet evolution on timescales of 100 kyr or longer (GREB-ISM v1.0). Ice sheets and ice shelves are

Climatic Conditions for modelling the Northern Hemisphere ice sheets throughout the ice age cycle [PDF]

Climate of the Past, 2007
The ice sheet-climate interaction as well as the climatic response to orbital parameters and atmospheric CO₂ concentration are examined in order to drive an ice sheet model throughout an ice age cycle.

Simulation of a fully coupled 3D glacial isostatic adjustment – ice sheet model for the Antarctic ice sheet over a glacial cycle [PDF]

Geoscientific Model Development, 2023
Glacial isostatic adjustment (GIA) has a stabilizing effect on the evolution of the Antarctic ice sheet by reducing the grounding line migration following ice melt. The timescale and strength of this feedback depends on the spatially varying viscosity of

Quantitative sub-ice and marine tracing of Antarctic sediment provenance (TASP v1.0) [PDF]

Geoscientific Model Development
Ice sheet models should be able to accurately simulate palaeo ice sheets to have confidence in their projections of future polar ice sheet mass loss and resulting global sea level rise.

Antarctic ice sheet response to sudden and sustained ice-shelf collapse (ABUMIP)

Journal of Glaciology, 2020
Antarctica's ice shelves modulate the grounded ice flow, and weakening of ice shelves due to climate forcing will decrease their ‘buttressing’ effect, causing a response in the grounded ice.

A theoretical steady state profile of ice sheets (two-dimentional model)

Antarctic Record, 1977
The Nye's kinematic theory of ice sheet profiles is revised on the basis of the conservation law of ice mass, because the Nye's ice sheet model or the revised Haefeli's model does not satisfy the ice mass conservation law and therefore they cannot have a

An ice sheet model validation framework for the Greenland ice sheet [PDF]

Geoscientific Model Development, 2017
We propose a new ice sheet model validation framework – the Cryospheric Model Comparison Tool (CmCt) – that takes advantage of ice sheet altimetry and gravimetry observations collected over the past several decades and is applied here to modeling of the ...
