Glacial cycles and ice-sheet modelling [PDF]

Climatic Change, 1982
An attempt is made to simulate the Pleistocene glacial cycles with a numerical model of the Northern Hemisphere ice sheets. This model treats the vertically-integrated ice flow along a meridian, including computation of bedrock adjustment and temperature distribution in the ice. Basal melt water is traced and controls ice-mass discharge.

On nonlinear strain theory for a viscoelastic material model and its implications for calving of ice shelves

Journal of Glaciology, 2019
In the current ice-sheet models calving of ice shelves is based on phenomenological approaches. To obtain physics-based calving criteria, a viscoelastic Maxwell model is required accounting for short-term elastic and long-term viscous deformation.

PLISMIP-ANT, an ice-sheet model intercomparison project [PDF]

, 2015
In the context of future climate change, understanding the nature and behaviour of ice sheets during warm intervals in Earth history is of fundamental importance.

Influence of temperature fluctuations on equilibrium
ice sheet volume [PDF]

The Cryosphere, 2018
Forecasting the future sea level relies on accurate modeling of the response of the Greenland and Antarctic ice sheets to changing temperatures. The surface mass balance (SMB) of the Greenland Ice Sheet (GrIS) has a nonlinear response to warming. Cold

Range of 21st century ice mass changes in the Filchner-Ronne region of Antarctica

Journal of Glaciology, 2023
Increases in ocean temperatures in the Filchner Ronne region of Antarctica are likely to result in increased ice mass loss and sea level rise. We constrain projections of the 21st century sea level contribution of this region using process-based ice ...

initMIP-Antarctica: an ice sheet model initialization experiment of ISMIP6 [PDF]

The Cryosphere, 2019
Ice sheet numerical modeling is an important tool to estimate the dynamic contribution of the Antarctic ice sheet to sea level rise over the coming centuries.

Recent Progress in Greenland Ice Sheet Modelling [PDF]

Current Climate Change Reports, 2017
This paper reviews the recent literature on numerical modelling of the dynamics of the Greenland ice sheet with the goal of providing an overview of advancements and to highlight important directions of future research. In particular, the review is focused on large-scale modelling of the ice sheet, including future projections, model parameterisations,

Eemian Greenland ice sheet simulated with a higher-order model shows strong sensitivity to surface mass balance forcing [PDF]

The Cryosphere, 2019
The Greenland ice sheet contributes increasingly to global sea level rise. Its history during past warm intervals is a valuable reference for future sea level projections.

The key role of topography in altering North Atlantic atmospheric circulation during the last glacial period [PDF]

, 2011
The Last Glacial Maximum (LGM; 21 000 yr before present) was a period of low atmospheric greenhouse gas concentrations, when vast ice sheets covered large parts of North America and Europe.

Simulating Marine Isotope Stage 7 with a coupled climate–ice sheet model [PDF]

Climate of the Past, 2020
It is widely accepted that orbital variations are responsible for the generation of glacial cycles during the late Pleistocene. However, the relative contributions of the orbital forcing compared to CO2 variations and other feedback mechanisms causing ...
