Sensitivity of the Ross Ice Shelf to environmental and glaciological controls [PDF]

The Cryosphere, 2022
The Ross Ice Shelf (RIS) is currently stable but recent observations have indicated that basal melt rates beneath the ice shelf are expected to increase.

Range of 21st century ice mass changes in the Filchner-Ronne region of Antarctica

Journal of Glaciology, 2023
Increases in ocean temperatures in the Filchner Ronne region of Antarctica are likely to result in increased ice mass loss and sea level rise. We constrain projections of the 21st century sea level contribution of this region using process-based ice ...

Reconstruction of ice-sheet changes in the Antarctic Peninsula since the Last Glacial Maximum [PDF]

, 2014
This paper compiles and reviews marine and terrestrial data constraining the dimensions and configuration of the Antarctic Peninsula Ice Sheet (APIS) from the Last Glacial Maximum (LGM) through deglaciation to the present day.

Modelling dynamic ice-sheet boundaries and grounding line migration using the level set method

Journal of Glaciology, 2020
Computing predictions of future sea level that include well-defined uncertainty bounds requires models that are capable of robustly simulating the evolution of ice sheets and glaciers.

Ice velocity changes in the Ross and Ronne sectors observed using satellite radar data from 1997 and 2009 [PDF]

The Cryosphere, 2012
We report changes in ice velocity of a 6.5 million km² region around South Pole encompassing the Filchner-Ronne and Ross Ice Shelves and a significant portion of the ice streams and glaciers that constitute their catchment areas ...

The role of near-terminus conditions in the ice-flow speed of Upernavik Isstrøm in northwest Greenland

Annals of Glaciology, 2023
Upernavik Isstrøm, the largest contributor to sea-level rise in northwest Greenland, has experienced complex and contrasting ice-flow-speed changes across its five outlets over the last two decades.

Stream hydrology controls on ice cliff evolution and survival on debris-covered glaciers [PDF]

Earth Surface Dynamics
Ice cliffs are melt hot spots that contribute disproportionately to melt on debris-covered glaciers. In this study, we investigate the impact of supraglacial stream hydrology on ice cliffs using in situ and remote sensing observations, streamflow ...

Of isbræ and ice streams [PDF]

Annals of Glaciology, 2003
AbstractFast-flowing ice streams and outlet glaciers provide the major avenues for ice flow from past and present ice sheets. These ice streams move faster than the surrounding ice sheet by a factor of 100 or more. Several mechanisms for fast ice-stream flow have been identified, leading to a spectrum of different ice-stream types.

Deformation in Rutford Ice Stream, West Antarctica: measuring shear-wave anisotropy from icequakes [PDF]

, 2013
Ice streams provide major drainage pathways for the Antarctic ice sheet. The stress distribution and style of flow in such ice streams produce elastic and rheological anisotropy, which informs ice-flow modelling as to how ice masses respond to external

Sensitivity of Heinrich-type ice-sheet surge characteristics to boundary forcing perturbations [PDF]

Climate of the Past, 2023
Heinrich-type ice-sheet surges are one of the prominent signals of glacial climate variability. They are characterised as abrupt, quasi-periodic episodes of ice-sheet instabilities during which large numbers of icebergs are released from the Laurentide ...
