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 ...

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 ...

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 ...

Ice streams in the Laurentide Ice Sheet: Identification, characteristics and comparison to modern ice sheets [PDF]
Earth-Science Reviews, 2015 AbstractThis paper presents a comprehensive review and synthesis of ice streams in the Laurentide Ice Sheet (LIS) based on a new mapping inventory that includes previously hypothesised ice streams and includes a concerted effort to search for others from across the entire ice sheet bed. The inventory includes 117 ice streams, which have been identified

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.

Active subglacial lakes and channelized water flow beneath the Kamb Ice Stream [PDF]
The Cryosphere, 2016 We identify two previously unknown subglacial lakes beneath the stagnated trunk of the Kamb Ice Stream (KIS). Rapid fill-drain hydrologic events over several months are inferred from surface height changes measured by CryoSat-2 altimetry and indicate ...

Antarctic Ice Sheet paleo-constraint database [PDF]
Earth System Science Data, 2023 We present a database of observational constraints on past Antarctic Ice Sheet changes during the last glacial cycle intended to consolidate the observations that represent our understanding of past Antarctic changes and for state-space estimation and ...
