The largest regional drivers of current surface elevation increases in the Antarctic Ice Sheet are associated with ice flow reconfiguration in previously active ice streams, highlighting the important role of ice dynamics in mass balance calculations. Here…
We present Bedmap3, the latest suite of gridded products describing surface elevation, ice-thickness and the seafloor and subglacial bed elevation of the Antarctic south of 60?°S. Bedmap3 incorporates and adds to all post-1950s datasets previously used for Bedmap2…
Geothermal heat flow (GHF) is a key basal boundary condition for Antarctic ice-sheet flow. Large-scale variations are resolved by several recent models but knowledge of the smaller-scale variations, crucial for ice sheet dynamics…
One of the key components of this research has been the mapping of Antarctic bed topography and ice thickness parameters that are crucial for modelling ice flow and hence for predicting future ice loss and the ensuing sea level rise. Supported by the Scientific Committee on Antarctic Research (SCAR)…
Sewage discharge into near-shore marine ecosystems is one of the most common forms of contamination that occurs in Antarctica today, and is likely to impact on the biota living in these habitats. In this study the morphological responses of four species of Abatus heart urchins (A. philippii, A.
The role played by Southern Hemisphere sea-ice in global climate is explored using an … Earth system climate model of intermediate complexity.
