Millennial-scale migration of the frozen/melted basal boundary, western Greenland ice sheet
Journal of Glaciology, 2022 The geometry and thermal structure of western Greenland ice sheet are known to have undergone relatively substantial change over the Holocene. Evolution of the frozen and melted fractions of the bed associated with the ice-sheet retreat over this time ...

Journal of Glaciology, 2023 Investigations of the time-dependent behavior of marine ice sheets and their sensitivity to basal conditions require numerical models because existing theoretical analyses focus only on steady-state configurations primarily with a power-law basal shear ...

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 ...

Reply to “Basal buoyancy and fast-moving glaciers: in defense of analytic force balance” by C. J. van der Veen (2016) [PDF]
The Cryosphere, 2017 Two approaches to ice-sheet modeling are available. Analytical modeling is the traditional approach (Van der Veen, 2016). It solves the force (momentum), mass, and energy balances to obtain three-dimensional solutions over time, beginning with the ...

The influence of inter-annual temperature variability on the Greenland Ice Sheet volume
Annals of Glaciology, 2023 The Greenland Ice Sheet has become an increasingly larger contributor to sea level rise in the past two decades and is projected to continue to lose mass.

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.

Nonlinear response of the Antarctic Ice Sheet to late Quaternary sea level and climate forcing [PDF]
The Cryosphere, 2019 Antarctic ice volume has varied substantially during the late Quaternary, with reconstructions suggesting a glacial ice sheet extending to the continental shelf break and interglacial sea level highstands of several meters.

Simulating the Holocene deglaciation across a marine-terminating portion of southwestern Greenland in response to marine and atmospheric forcings [PDF]
The Cryosphere, 2022 Numerical simulations of the Greenland Ice Sheet (GrIS) over geologic timescales can greatly improve our knowledge of the critical factors driving GrIS demise during climatically warm periods, which has clear relevance for better predicting GrIS behavior

Pre-LGM Northern Hemisphere ice sheet topography [PDF]
Climate of the Past, 2013 We here reconstruct the paleotopography of Northern Hemisphere ice sheets during the glacial maxima of marine isotope stages (MIS) 5b and 4.We employ a combined approach, blending geologically based reconstruction and numerical modeling, to arrive at ...

Ice mass loss sensitivity to the Antarctic ice sheet basal thermal state
Nature Communications, 2022 This study uses ice sheet modeling experiments to show that thawing portions of the Antarctic ice sheet bed can increase century-scale mass loss, particularly in the Wilkes and Enderby Land regions of East Antarctica.
