, 2020 . Simulations of the glacial–interglacial history of the Antarctic Ice Sheet provide insights into dynamic threshold behavior and estimates of the ice sheet's contributions to global sea-level changes for the past, present and future.

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.

Investigating the impact of sub-ice shelf melt on Antarctic ice sheet spin-up and projections [PDF]
The CryosphereSub-ice shelf melting is critical for the stability of the Antarctic ice sheet, as it influences ice-shelf buttressing that reduces grounded ice flow. Previous studies have emphasized that uncertainties in the state of sub-ice shelf melting contribute to

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

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.

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

Modeling the Greenland englacial stratigraphy [PDF]
The Cryosphere, 2021 Radar reflections from the interior of the Greenland ice sheet contain a comprehensive archive of past accumulation rates, ice dynamics, and basal melting. Combining these data with dynamic ice sheet models may greatly aid model calibration, improve past

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.

A new coupled ice sheet/climate model: description and sensitivity to model physics under Eemian, Last Glacial Maximum, late Holocene and modern climate conditions [PDF]
Geoscientific Model Development, 2011 The need to better understand long-term climate/ice sheet feedback loops is motivating efforts to couple ice sheet models into Earth System models which are capable of long-timescale simulations. In this paper we describe a coupled model that consists of
