Cosmogenic-nuclide data from Antarctic nunataks can constrain past ice sheet instabilities [PDF]
The Cryosphere, 2023 We apply geologic evidence from ice-free areas in Antarctica to evaluate model simulations of ice sheet response to warm climates. This is important because such simulations are used to predict ice sheet behaviour in future warm climates, but geologic ...

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

Last deglaciation of northern continental Europe
Cuadernos de Investigación Geográfica, 2015 Correlation of main ice sheet limits in northern continental Europe during Late Weichselian is presented, based on available data concerning occurrence of ice-marginal formations and their radiometric dating.

The Cryosphere, 2019 . The subglacial environment of the Greenland Ice Sheet (GrIS) is poorly constrained both in its bulk properties, for example geology, the presence of sediment, and the presence of water, and interfacial conditions, such as roughness and bed rheology ...

The Cryosphere, 2020 . Changes in ocean temperature and salinity are expected to be an important determinant of the Greenland ice sheet's future sea level contribution. Yet, simulating the impact of these changes in continental-scale ice sheet models remains challenging due ...

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.

Quantifying the uncertainty in the Eurasian ice-sheet geometry at the Penultimate Glacial Maximum (Marine Isotope Stage 6) [PDF]
The Cryosphere, 2023 The North Sea Last Interglacial sea level is sensitive to the fingerprint of mass loss from polar ice sheets. However, the signal is complicated by the influence of glacial isostatic adjustment driven by Penultimate Glacial Period ice-sheet changes, and ...

PLISMIP-ANT, an ice-sheet model intercomparison project [PDF]
, 2015 In the context of future climate change, understanding the nature and behaviour of ice sheets during warm intervals in Earth history is of fundamental importance.

Ice Streams of the Laurentide Ice Sheet [PDF]
Géographie physique et Quaternaire, 2006 Ice streams had a major influence on the configuration and the stability of the Laurentide Ice Sheet. Their identification is crucial for an understanding of ice sheet behaviour and their importance is reflected by the recent increase in paleo-ice stream research.

Ice sheet contributions to future sea-level rise from structured expert judgment
Proceedings of the National Academy of Sciences of the United States of America, 2019 Significance Future sea level rise (SLR) poses serious threats to the viability of coastal communities, but continues to be challenging to project using deterministic modeling approaches. Nonetheless, adaptation strategies urgently require quantification
