Global ice sheet modeling [PDF]
, 1994 The University of Maine conducted this study for Pacific Northwest Laboratory (PNL) as part of a global climate modeling task for site characterization of the potential nuclear waste respository site at Yucca Mountain, NV. The purpose of the study was to develop a global ice sheet dynamics model that will forecast the three-dimensional configuration of

Modeling the Antarctic ice sheet [PDF]
Annals of Glaciology, 1997 A three-dimensional (3-D), high-resolution, non-linearly viscous, non-isothermal ice-sheet model is employed to calculate the “present-day” equilibrium regime of the Antarctic ice sheet and its evolution during the last glacial cycle.

The effect of buttressing on grounding line dynamics
Journal of Glaciology, 2018 Determining the position and stability of the grounding line of a marine ice sheet is a major challenge for ice-sheet models. Here, we investigate the role of lateral shear and ice-shelf buttressing in grounding line dynamics by extending an existing ...

Investigating the sensitivity of numerical model simulations of the modern state of the Greenland ice-sheet and its future response to climate change [PDF]
The Cryosphere, 2010 Ice thickness and bedrock topography are essential boundary conditions for numerical modelling of the evolution of the Greenland ice-sheet (GrIS). The datasets currently in use by the majority of GrIS modelling studies are over two decades old and based ...

ATAT 1.1, the Automated Timing Accordance Tool for comparing ice-sheet model output with geochronological data [PDF]
Geoscientific Model Development, 2019 Earth's extant ice sheets are of great societal importance given their ongoing and potential future contributions to sea-level rise. Numerical models of ice sheets are designed to simulate ice-sheet behaviour in response to climate changes but to be ...

Deglacial climate changes as forced by different ice sheet reconstructions [PDF]
Climate of the Past, 2023 During the last deglaciation, the climate evolves from a cold state at the Last Glacial Maximum (LGM) at 21 ka (thousand years ago) with large ice sheets to the warm Holocene at ∼9 ka with reduced ice sheets.

Mid-Holocene thinning of David Glacier, Antarctica: chronology and controls [PDF]
The Cryosphere, 2021 Quantitative satellite observations only provide an assessment of ice sheet mass loss over the last four decades. To assess long-term drivers of ice sheet change, geological records are needed. Here we present the first millennial-scale reconstruction of

High climate model dependency of Pliocene Antarctic ice-sheet predictions
Nature Communications, 2018 Ice sheet models forced by climate model output indicate ice-sheet retreat during the Pliocene, yet concerns remain regarding potential model bias. Here, the authors present results from the Pliocene Ice-sheet Modelling Intercomparison Project, and show ...

The speedup of Pine Island Ice Shelf between 2017 and 2020: revaluating the importance of ice damage
Journal of Glaciology, 2023 From 2017 to 2020, three significant calving events took place on Pine Island Glacier, West Antarctica. Ice-shelf velocities changed over this period and the calving events have been suggested as possible drivers.
