Calibrating an Ice Sheet Model Using High-Dimensional Binary Spatial Data [PDF]
, 2015 Rapid retreat of ice in the Amundsen Sea sector of West Antarctica may cause drastic sea level rise, posing significant risks to populations in low-lying coastal regions.

Ice shelf fracture parameterization in an ice sheet model [PDF]
The Cryosphere, 2017 Floating ice shelves exert a stabilizing force onto the inland ice sheet. However, this buttressing effect is diminished by the fracture process, which on large scales effectively softens the ice, accelerating its flow, increasing calving, and ...

Shallow shelf approximation as a “sliding law” in a thermomechanically coupled ice sheet model [PDF]
, 2008 [1] The shallow shelf approximation, a balance of membrane stresses for ice flow, is an effective "sliding law" for ice sheet modeling. Our use of it as a sliding law becomes a standard model for ice stream flow when the sliding velocity is large (100 m ...

Hysteresis of the Antarctic Ice Sheet With a Coupled Climate‐Ice‐Sheet Model
Geophysical Research LettersThe stability of the Antarctic ice sheet under different fixed CO2 levels and orbital configurations is explored using a coupled climate‐ice sheet model, starting from either a pre‐industrial ice sheet or an ice‐free, isostatically rebounded geometry ...

A technique for generating consistent ice sheet initial conditions for coupled ice sheet/climate models [PDF]
Geoscientific Model Development, 2014 A transient technique for generating ice sheet preindustrial initial conditions for long-term coupled ice sheet/climate model simulations is developed and demonstrated over the Greenland ice sheet using the Community Earth System Model (CESM). End-member

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 ...

A Gaussian process emulator for simulating ice sheet–climate interactions on a multi-million-year timescale: CLISEMv1.0 [PDF]
Geoscientific Model Development, 2021 On multi-million-year timescales, fully coupled ice sheet–climate simulations are hampered by computational limitations, even at coarser resolutions and when using asynchronous coupling schemes.

The GRISLI-LSCE contribution to the Ice Sheet Model Intercomparison Project for phase 6 of the Coupled Model Intercomparison Project (ISMIP6) – Part 2: Projections of the Antarctic ice sheet evolution by the end of the 21st century [PDF]
The Cryosphere, 2021 The Antarctic ice sheet's contribution to global sea level rise over the 21st century is of primary societal importance and remains largely uncertain as of yet.
