The impact of spatially varying ice sheet basal conditions on sliding at glacial time scales
Spatially variable basal conditions are thought to govern how ice sheets behave at glacial time scales (>1000 years) and responsible for changes in dynamics between the core and peripheral regions of the Laurentide and Fennoscandian ice sheets.

The role of subtemperate slip in thermally driven ice stream margin migration [PDF]
The amount of ice discharged by an ice stream depends on its width, and the widths of unconfined ice streams such as the Siple Coast ice streams in West Antarctica have been observed to evolve on decadal to centennial timescales.

Description and evaluation of the Community Ice Sheet Model (CISM) v2.1
. We describe and evaluate version 2.1 of the Community Ice Sheet Model (CISM). CISM is a parallel, 3-D thermomechanical model, written mainly in Fortran, that solves equations for the momentum balance and the thickness and temperature evolution of ice ...

The evolution of future Antarctic surface melt using PISM-dEBM-simple [PDF]
It is virtually certain that Antarctica's contribution to sea-level rise will increase with future warming, although competing mass balance processes hamper accurate quantification of the exact magnitudes.

Positive feedbacks drive the Greenland ice sheet evolution in millennial-length MAR–GISM simulations under a high-end warming scenario [PDF]
Understanding the complex interactions between the Greenland ice sheet (GrIS) and the atmosphere is crucial for projecting its future sea level contribution. However, studying these interactions remains challenging, as it requires high-resolution climate

Greenland ice sheet mass balance assessed by PROMICE (1995–2015)
The Programme for Monitoring of the Greenland Ice Sheet (PROMICE) has measured ice-sheet elevation and thickness via repeat airborne surveys circumscribing the ice sheet at an average elevation of 1708 ± 5 m (Sørensen et al. 2018).

initMIP-Antarctica: an ice sheet model initialization experiment of ISMIP6
. 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. The influence of initial conditions on ice sheet model simulations, however, is still unclear.
