Marine ice sheet experiments with the Community Ice Sheet Model [PDF]

The Cryosphere, 2021
Ice sheet models differ in their numerical treatment of dynamical processes. Simulations of marine-based ice are sensitive to the choice of Stokes flow approximation and basal friction law and to the treatment of stresses and melt rates near the ...

Experimental protocol for sea level projections from ISMIP6 stand-alone ice sheet models [PDF]

The Cryosphere, 2020
Projection of the contribution of ice sheets to sea level change as part of the Coupled Model Intercomparison Project Phase 6 (CMIP6) takes the form of simulations from coupled ice sheet–climate models and stand-alone ice sheet models, overseen by the ...

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.

The Last Scottish Ice Sheet [PDF]

Earth and Environmental Science Transactions of the Royal Society of Edinburgh, 2018
ABSTRACTThe last Scottish Ice Sheet (SIS) expanded from a pre-existing ice cap after ∼35 ka. Highland ice dominated, with subsequent build-up of a Southern Uplands ice mass. The Outer Hebrides, Skye, Mull, the Cairngorms and Shetland supported persistent independent ice centres.

An ice sheet model validation framework for the Greenland ice sheet [PDF]

Geoscientific Model Development, 2017
We propose a new ice sheet model validation framework – the Cryospheric Model Comparison Tool (CmCt) – that takes advantage of ice sheet altimetry and gravimetry observations collected over the past several decades and is applied here to modeling of the ...

Observing and Modeling Ice Sheet Surface Mass Balance

Reviews of Geophysics, 2019
Surface mass balance (SMB) provides mass input to the surface of the Antarctic and Greenland Ice Sheets and therefore comprises an important control on ice sheet mass balance and resulting contribution to global sea level change.

Competing climate feedbacks of ice sheet freshwater discharge in a warming world [PDF]

Nature Communications
Freshwater discharge from ice sheets induces surface atmospheric cooling and subsurface ocean warming, which are associated with negative and positive feedbacks respectively. However, uncertainties persist regarding these feedbacks’ relative strength and

PISM-LakeCC: Implementing an adaptive proglacial lake boundary in an ice sheet model [PDF]

The Cryosphere, 2022
During the Late Pleistocene and Holocene retreat of paleo-ice sheets in North America and Europe, vast proglacial lakes existed along the land terminating margins.
