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 ...

Solitary flexural–gravity waves in three dimensions [PDF]
, 2018 The focus of this work is on three-dimensional nonlinear flexural–gravity waves, propagating at the interface between a fluid and an ice sheet. The ice sheet is modelled using the special Cosserat theory of hyperelastic shells satisfying Kirchhoff's ...

Instantaneous Antarctic ice-sheet mass loss driven by thinning ice shelves [PDF]
, 2019 Recent observations show that the rate at which the Antarctic Ice Sheet (AIS) is contributing to sea level rise is increasing. Increasing ice-ocean heat exchange has the potential to induce substantial mass loss through the melting of its ice shelves ...

The Greenland-Ice-Sheet evolution over the last 24 000 years: insights from model simulations evaluated against ice-extent markers [PDF]
The CryosphereContinental ice sheets retain a long-term memory stored in their geometry and thermal properties. In Greenland, this creates a disequilibrium with the present climate, as the ice sheet is still adjusting to past changes that occurred over millennial ...

Thermomechanical modelling of the Scandinavian ice sheet: implications for ice-stream formation [PDF]
, 1999 This work attempts to explain the fan-like landform assemblages observed in satellite images of the area covered by the former Scandinavian ice sheet (SIS). These assemblages have been interpreted as evidence of large ice streams within the SIS.

Advances in modelling subglacial lakes and their interaction with the Antarctic ice sheet [PDF]
, 2016 Subglacial lakes have long been considered hydraulically isolated water bodies underneath ice sheets. This view changed radically with the advent of repeat-pass satellite altimetry and the discovery of multiple lake discharges and water infill ...

Capturing the interactions between ice sheets, sea level and the solid Earth on a range of timescales: a new “time window” algorithm [PDF]
Geoscientific Model Development, 2022 Retreat and advance of ice sheets perturb the gravitational field, solid surface and rotation of the Earth, leading to spatially variable sea-level changes over a range of timescales O(100−6 years), which in turn feed back onto ice-sheet dynamics ...
