Modeling the elastic transmission of tidal stresses to great distances inland in channelized ice streams [PDF]

open access: yesThe Cryosphere, 2014
Geodetic surveys suggest that ocean tides can modulate the motion of Antarctic ice streams, even at stations many tens of kilometers inland from the grounding line.

The role of subtemperate slip in thermally driven ice stream margin migration [PDF]

open access: yesThe Cryosphere, 2018
The amount of ice discharged by an ice stream depends on its width, and the widths of unconfined ice streams such as the Siple Coast ice streams in West Antarctica have been observed to evolve on decadal to centennial timescales.

Frequency response of ice streams. [PDF]

open access: yesProc Math Phys Eng Sci, 2012
Changes at the grounding line of ice streams have consequences for inland ice dynamics and hence sea level. Despite substantial evidence documenting upstream propagation of frontal change, the mechanisms by which these changes are transmitted inland are not well understood.

Modeling Ice Shelf/Ocean Interaction in Antarctica: A Review [PDF]

open access: yesOceanography, 2016
The most rapid loss of ice from the Antarctic Ice Sheet is observed where ice streams flow into the ocean and begin to float, forming the great Antarctic ice shelves that surround much of the continent.

Antarctic palaeo-ice streams [PDF]

open access: yesEarth-Science Reviews, 2012
We review the geomorphological, sedimentological and chronological evidence for palaeo-ice streams on the continental shelf of Antarctica and use this information to investigate basal conditions and processes, and to identify factors controlling grounding-line retreat.

Tidal controls on the flow of ice streams [PDF]

open access: yesGeophysical Research Letters, 2016
The flow of many Antarctic ice streams is known to be significantly influenced by tides. In the past, modeling studies have implemented the tidal forces acting on a coupled ice stream/ice shelf system in a number of different ways, but the consequences ...

Ice-stream flow switching by up-ice propagation of instabilities along glacial marginal troughs [PDF]

open access: yesThe Cryosphere, 2019
Ice-stream networks constitute the arteries of ice sheets through which large volumes of glacial ice are rapidly delivered from the continent to the ocean.

Subglacial hydrological control on flow of an Antarctic Peninsula palaeo-ice stream [PDF]

open access: yesThe Cryosphere, 2019
Basal hydrological systems play an important role in controlling the dynamic behaviour of ice streams. Data showing their morphology and relationship to geological substrates beneath modern ice streams are, however, sparse and difficult to collect.

‘Stable’ and ‘unstable’ are not useful descriptions of marine ice sheets in the Earth's climate system

open access: yesJournal of Glaciology, 2023
Investigations of the time-dependent behavior of marine ice sheets and their sensitivity to basal conditions require numerical models because existing theoretical analyses focus only on steady-state configurations primarily with a power-law basal shear ...
