The Antarctic Ice Sheet sliding law inferred from seismic observations Open
The response of the Antarctic ice sheet to climate change and its contribution to sea level under different emission scenarios are subject to large uncertainties. A key uncertainty is the slipperiness at the ice sheet base and how it is pa…

The glacial systems model (GSM) Version 24G Open
We document the glacial system model (GSM), which includes a 3D thermo-mechanically coupled glaciological ice sheet model. The GSM is designed for large ensemble modelling in glacial cycle contexts. A distinguishing feature is the extent t…

The comparative role of physical system processes in Hudson Strait ice stream cycling: a comprehensive model-based test of Heinrich event hypotheses Open
Despite their recognized significance on global climate and extensive research efforts, the mechanism(s) driving Heinrich events remain(s) a subject of debate. Here, we use the 3D thermomechanically coupled glacial systems model (GSM) to e…

Modeling sensitivities of thermally and hydraulically driven ice stream surge cycling Open
Modeling ice sheet instabilities is a numerical challenge of potentially high real-world relevance. Yet, differentiating between the impacts of model physics, numerical implementation choices, and numerical errors is not straightforward. H…

Towards confidence in numerical modeling of ice stream cycling Open
Some ice sheets and glaciers experience long quiescent periods interspersed with short periods of rapid ice advance, such as the binge-purge-type cycling hypothesized to be associated with Heinrich Events. Modeling ice stream activation/de…
