An ice-sheet scale comparison of eskers with modelled subglacial drainage routes [PDF]

, 2015
Eskers record the signature of channelised meltwater drainage during deglaciation providing vital information on the nature and evolution of subglacial drainage.

Switch-off of a major enhanced ice flow unit in East Antarctica [PDF]

, 2006
The East Antarctic Ice Sheet (EAIS) is the largest reservoir of ice on the planet by an order of magnitude. Compared with the West Antarctic Ice Sheet (WAIS), it is traditionally considered to be relatively stable, with only minor adjustments to its ...

Speed-up, slowdown, and redirection of ice flow on neighbouring ice streams in the Pope, Smith, and Kohler region of West Antarctica [PDF]

The Cryosphere
The ice streams feeding the Dotson and Crosson ice shelves are some of the fastest changing in West Antarctica. We use satellite observations to measure the change in ice speed and flow direction on eight ice streams in the Pope, Smith, and Kohler region

Formation of ribbed bedforms below shear margins and lobes of palaeo-ice streams [PDF]

The Cryosphere, 2021
Conceptual ice stream land systems derived from geomorphological and sedimentological observations provide constraints on ice–meltwater–till–bedrock interactions on palaeo-ice stream beds. Within these land systems, the spatial distribution and formation

Airborne radar evidence for tributary flow switching in Institute Ice Stream, West Antarctica: implications for ice sheet configuration and dynamics [PDF]

, 2015
Despite the importance of ice streaming to the evaluation of West Antarctic Ice Sheet (WAIS) stability we know little about mid- to long-term dynamic changes within the Institute Ice Stream (IIS) catchment.

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

Oceanography, 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.

Ocean-forced evolution of the Amundsen Sea catchment, West Antarctica, by 2100 [PDF]

The Cryosphere, 2020
The response of ice streams in the Amundsen Sea Embayment (ASE) to future climate forcing is highly uncertain. Here we present projections of 21st century response of ASE ice streams to modelled local ocean temperature change using a subset of Coupled ...

Resource-aware mining of data streams [PDF]

, 2005
Mining data streams has raised a number of research challenges for the data mining community. These challenges include the limitations of computational resources, especially because mining streams of data most likely be done on a mobile device with ...

A thicker Antarctic ice stream during the mid-Pliocene warm period

Communications Earth & Environment, 2023
Ice streams regulate most ice mass loss in Antarctica. Determining ice stream response to warmer conditions during the Pliocene could provide insights into their future behaviour, but this is hindered by a poor representation of subglacial topography in ...

Potential subglacial lake locations and meltwater drainage pathways beneath the Antarctic and Greenland ice sheets [PDF]

, 2013
We use the Shreve hydraulic potential equation as a simplified approach to investigate potential subglacial lake locations and meltwater drainage pathways beneath the Antarctic and Greenland ice sheets. We validate the method by demonstrating its ability
