ice streams on the continental shelf of Antarctica and use this information to investigate …

Tip** point in ice-sheet grounding-zone melting due to ocean water intrusion

AT Bradley, IJ Hewitt - Nature Geoscience, 2024 - nature.com
Marine ice sheets are highly sensitive to submarine melting in their grounding zones, where
they transition between grounded and floating ice. Recently published studies of the …

Marine ice sheet collapse potentially under way for the Thwaites Glacier Basin, West Antarctica

I Joughin, BE Smith, B Medley - Science, 2014 - science.org
Resting atop a deep marine basin, the West Antarctic Ice Sheet has long been considered
prone to instability. Using a numerical model, we investigated the sensitivity of Thwaites …

Potential sea-level rise from Antarctic ice-sheet instability constrained by observations

C Ritz, TL Edwards, G Durand, AJ Payne, V Peyaud… - Nature, 2015 - nature.com
Large parts of the Antarctic ice sheet lying on bedrock below sea level may be vulnerable to
marine-ice-sheet instability (MISI), a self-sustaining retreat of the grounding line triggered by …

Retreat of Pine Island Glacier controlled by marine ice-sheet instability

L Favier, G Durand, SL Cornford… - Nature Climate …, 2014 - nature.com
Over the past 40 years Pine Island Glacier in West Antarctica has thinned at an accelerating

Antarctic ice sheet response to sudden and sustained ice-shelf collapse (ABUMIP)

S Sun, F Pattyn, EG Simon, T Albrecht… - Journal of …, 2020 - cambridge.org
Antarctica's ice shelves modulate the grounded ice flow, and weakening of ice shelves due
to climate forcing will decrease their 'buttressing'effect, causing a response in the grounded …

Regularized Coulomb friction laws for ice sheet sliding: Application to Pine Island Glacier, Antarctica

I Joughin, BE Smith, CG Schoof - Geophysical research letters, 2019 - Wiley Online Library
The choice of the best basal friction law to use in ice‐sheet models remains a source of
uncertainty in projections of sea level. The parameters in commonly used friction laws can …

Antarctic subglacial conditions inferred from a hybrid ice sheet/ice stream model

F Pattyn - Earth and Planetary Science Letters, 2010 - Elsevier
Subglacial conditions of large polar ice sheets remain poorly understood, despite recent
