Antarctic palaeo-ice streams [PDF]
Earth-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 ...

Tidal controls on the flow of ice streams [PDF]
Geophysical 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 ...

Frequency response of ice streams. [PDF]
Proc 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.

On the Pulling Power of Ice Streams [PDF]
Journal of Glaciology, 1992 Gravity wants to pull an ice sheet to the center of the Earth, but cannot because the Earth\u27s crust is in the way, so ice is pushed out sideways instead. Or is it? The ice sheet sees nothing preventing it from spreading out except air, which is much

Subglacial hydrology and the formation of ice streams. [PDF]
Proc Math Phys Eng Sci, 2014 Antarctic ice streams are associated with pressurized subglacial meltwater but the role this water plays in the dynamics of the streams is not known. To address this, we present a model of subglacial water flow below ice sheets, and particularly below ice streams.

West Antarctic Ice Streams [PDF]
Reviews of Geophysics, 1977 Solar heat is the acknowledged driving force for climatic change. However, ice sheets are also capable of causing climatic change. This property of ice sheets derives from the facts that ice and rock are crystalline whereas the oceans and atmosphere are ...

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.

, 2021 <div>Ice streams are the arteries through which a large fraction of the ice lost from Antarctica is discharged. With the introduction of "higher order" mechanics, the representation of ice streams in ice sheet models appears to have become more robust, eliminating previously ubiquitous grid effects.

Stochastic ice stream dynamics [PDF]
Proceedings of the National Academy of Sciences, 2016 Significance Ice streams form the backbone of the flow field of ice sheets. They are known to exhibit a complex spatiotemporal dynamics, which is largely not well understood. Understanding the controls on such dynamics is crucial to sea level change projections as well as to the interpretation of paleorecords.

Footprint of the Baltic Ice Stream: geomorphic evidence for shifting ice stream pathways
Boreas, 2023 The Baltic Ice Stream, a large fast‐flowing sector of the last Fennoscandian Ice Sheet that occupied the present‐day Baltic Sea basin, was first conceptualized in the earliest days of glacial geological research in Scandinavia. Landform and sedimentological evidence from the terrestrial margins support the concept and numerical ice‐sheet models ...
