Within Earth’s ice sheets, fast-flowing ice streams are the principal components through which ice and sediment are discharged, accounting for c. 90% of the ice lost from the Antarctic today […]
The often large ocean tides around Antarctica can greatly affect the flow of ice streams even long distances upstream of their grounding lines. Observing and modelling this interaction serves as […]
Research beneath Antarctica’s vast ice sheets has revealed mountain ranges the size of the Alps, lakes bigger than Windermere, rivers, streams and ancient volcanoes. But why should we care? Professor […]
Flow dynamics of the ice streams that drain the Antarctic Ice Sheet are heavily influenced by processes at the bed. Natural seismic activity generated beneath an ice stream is associated […]
Most comprehensive ice loss model A new international study is the first to use a high-resolution, large-scale computer model to estimate how much ice the West Antarctic Ice Sheet could […]
Accurate dynamical models of the Antarctic ice sheet with carefully specified initial conditions and well-calibrated rheological parameters are needed to forecast global sea level. By adapting an inverse method previously […]
BEAMISH drilled through over 2 km of ice on Rutford Ice Stream to discover when the West Antarctic Ice Sheet last collapsed and how water and soft sediments beneath it help the ice flow towards the sea.
Multibeam swath bathymetry data sets collected over the past two decades have been compiled to identify palaeo-ice stream pathways in the easternmost Amundsen Sea Embayment. We mapped ~ 3000 glacial […]
Recent studies have aroused concerns over the potential for ice draining the Weddell Sea sector of West Antarctica to figure more prominently in sea-level contributions should buttressing from the Filchner-Ronne […]
Several recent studies predict that the West Antarctic Ice Sheet will become increasingly unstable under warmer conditions. Insights on such change can be assisted through investigations of the subglacial landscape, […]
We present ice-penetrating radar evidence for ancient (pre-glacial) and extensive erosion surfaces preserved beneath the upstream Institute and Möller ice streams, West Antarctica. Radar data reveal a smooth, laterally continuous, […]
The Amundsen Sea Embayment of West Antarctica hosts one of the most rapidly changing sectors of the West Antarctic Ice Sheet. With the fastest-flowing ice streams in Antarctica, the region […]
