Tides play an important role in ice sheet dynamics by modulating ice stream velocity, fracturing, and moving ice shelves and mixing water beneath them. Any changes in ice shelf extent […]
Marine and terrestrial geological and marine geophysical data that constrain deglaciation since the Last Glacial Maximum (LGM) of the sector of the West Antarctic Ice Sheet (WAIS) draining into the […]
Mega-scale glacial lineations (MSGLs) are a characteristic landform on ice stream beds. Solving the puzzle of their formation is key to understanding how ice interacts with its bed and how […]
A linearized perturbation about a two-dimensional Vialov-Nye icesheet profile is used to investigate the sensitivity of the divide position at Siple Dome, West Antarctica, to small changes in the accumulation […]
There remain large regions of scientific interest in the Antarctic that are not instrumented. These include highly dynamic ice streams and glaciers that are difficult or impossible to reach safely […]
Meltwater generated beneath the Antarctic Ice Sheet exerts a strong influence on the speed of ice flow, in particular for major ice streams1, 2. The subglacial meltwater also influences ocean […]
Icequakes unlock secrets of icestreams Measuring tiny icequakes is helping British Antarctic Survey scientists investigate ice streams despite the challenging environment they have to work in. The work of Emma […]
The East Antarctic Ice Sheet (EAIS) is the largest continental ice mass on Earth, and documenting its evolution since the Last Glacial Maximum (LGM) is important for understanding its present-day […]
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 […]
Inter-ice stream areas cover significant portions of Antarctica’s formerly glaciated shelves, but have been largely neglected in past geological studies because of overprinting by iceberg scours. Here, we present results […]
Increasing evidence for an elaborate subglacial drainage network underneath modern Antarctic ice sheets suggests that basal meltwater has an important influence on ice stream flow. Swath bathymetry surveys from previously […]
The Pine Island Glacier ice-drainage basin has been cited as the part of the West Antarctic ice sheet most prone to substantial retreat on human time-scales. Here we review the […]
