A technique for generating consistent ice sheet initial conditions for coupled ice sheet/climate models [PDF]
Geoscientific Model Development, 2013 Abstract. A transient technique for generating ice sheet preindustrial initial conditions for long-term coupled ice sheet/climate model simulations is developed and demonstrated over the Greenland ice sheet using the Community Earth System Model (CESM).

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.

Exposure age and ice-sheet model constraints on Pliocene East Antarctic ice sheet dynamics [PDF]
Nature Communications, 2015 AbstractThe Late Pliocene epoch is a potential analogue for future climate in a warming world. Here we reconstruct Plio-Pleistocene East Antarctic Ice Sheet (EAIS) variability using cosmogenic nuclide exposure ages and model simulations to better understand ice sheet behaviour under such warm conditions.

Journal of Glaciology, 2017 The basal interface of glaciers is generally not directly observable. Geophysical inverse methods are therefore used to infer basal parameters from surface observations.

Influence of ice-sheet geometry and supraglacial lakes on seasonal ice-flow variability [PDF]
The Cryosphere, 2013 Supraglacial lakes play an important role in establishing hydrological connections that allow lubricating seasonal meltwater to reach the base of the Greenland Ice Sheet.

A Three-Dimensional Model of the Antarctic Ice Sheet [PDF]
Annals of Glaciology, 1988 A preliminary version of a three-dimensional ice-sheet model for later use in climate models, but excluding ice shelves and basal sliding, is presented and applied to the Antarctic ice sheet. In the model, the three-dimensional fields of velocity and temperature are calculated in the coupled mode, and the temperature equation is integrated for 150 000 ...

A synthesis of the basal thermal state of the Antarctic ice sheet
Journal of GlaciologyThe basal thermal state of the Antarctic ice sheet (AIS)—whether the base is frozen or thawed—fundamentally underpins its flow and is an important factor in understanding its large-scale response to external forcings.

The paradigm shift in Antarctic ice sheet modelling [PDF]
Nature Communications, 2018 The Antarctic ice sheet is one of the largest potential contributors to future sea level rise. Predicting its future behaviour using physically-based ice sheet models has been a bottleneck for the past decades, but major advances are ongoing.

Machine-learning emulation of the modeled basal thermal state for Totten Glacier
Journal of GlaciologyThe basal thermal state of the Antarctic ice sheet strongly influences ice dynamics and mass balance. Although basal thermal states can be simulated using ice-sheet models, significant uncertainties persist, with poorly constrained geothermal heat flux ...

The Greenland Ice Sheet Large Ensemble (GrISLENS): simulating the future of Greenland under climate variability [PDF]
The CryosphereThe Greenland ice sheet has lost ice at an increasing pace over recent decades, driven by a combination of human-caused climate change and internal variability in the climate system.
