ICESHEET 1.0: a program to produce paleo-ice sheet reconstructions with minimal assumptions [PDF]
Geoscientific Model Development, 2016 We describe a program that produces paleo-ice sheet reconstructions using an assumption of steady-state, perfectly plastic ice flow behaviour. It incorporates three input parameters: ice margin, basal shear stress and basal topography.

An improved Antarctic dataset for high resolution numerical ice sheet models (ALBMAP v1) [PDF]
Earth System Science Data, 2010 The dataset described in this paper (ALBMAP) has been created for the purposes of high-resolution numerical ice sheet modelling of the Antarctic Ice Sheet. It brings together data on the ice sheet configuration (e.g.

Modelling the Antarctic Ice Sheet across the mid-Pleistocene transition – implications for Oldest Ice [PDF]
The Cryosphere, 2019 The international endeavour to retrieve a continuous ice core, which spans the middle Pleistocene climate transition ca. 1.2–0.9 Myr ago, encompasses a multitude of field and model-based pre-site surveys. We expand on the current efforts to locate

Geology datasets in North America, Greenland and surrounding areas for use with ice sheet models [PDF]
Earth System Science Data, 2019 The ice–substrate interface is an important boundary condition for ice sheet modelling. The substrate affects the ice sheet by allowing sliding through sediment deformation and accommodating the storage and drainage of subglacial water.

Ice-sheet configuration in the CMIP5/PMIP3 Last Glacial Maximum experiments [PDF]
Geoscientific Model Development, 2015 We describe the creation of a data set describing changes related to the presence of ice sheets, including ice-sheet extent and height, ice-shelf extent, and the distribution and elevation of ice-free land at the Last Glacial Maximum (LGM), which were

Data assimilation and prognostic whole ice sheet modelling with the variationally derived, higher order, open source, and fully parallel ice sheet model VarGlaS [PDF]
The Cryosphere, 2013 We introduce a novel, higher order, finite element ice sheet model called VarGlaS (Variational Glacier Simulator), which is built on the finite element framework FEniCS.

Effect of an orientation-dependent non-linear grain fluidity on bulk directional enhancement factors
Journal of Glaciology, 2021 Bulk directional enhancement factors are determined for axisymmetric (girdle and single-maximum) orientation fabrics using a transversely isotropic grain rheology with an orientation-dependent non-linear grain fluidity.

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.

Bed topography and marine ice-sheet stability
Journal of Glaciology, 2022 This paper examines the effect of basal topography and strength on the grounding-line position, flux and stability of rapidly-sliding ice streams.
