Parallel numerical modelling of ice flow in Antarctica
The Antarctic Ice Sheet is made up of the West Antarctic Ice Sheet (WAIS) and the much larger East Antarctic Ice Sheet (EAIS). Previous numerical models have focussed on ice flow in WAIS, since the size of the EAIS has precluded studies at a resolution adequate to identify complex flow features. The...
