New observations have revealed that changes in ice sheets are occurring at rates far exceeding the millennial time scales predicted by traditional models (Paterson, 1994). Our inability to fully model these changes limits our ability to make predictions about their future contributions to sea-level rise (Intergovernmental Panel on Climate Change, 2007). Many of these changes are taking place in the large ice streams and outlet glaciers that drain the interiors of ice sheets. One such dynamic region is the Whillans Ice Stream (WIS), a large outlet for ice that drains from the interior of the West Antarctic Ice Sheet (WAIS) into the Ross Ice Shelf.
