Scale of subglacial to sub-ice shelf facies variability, Eastern Basin, Ross Sea
The Eastern Basin within the Ross Sea records changes in the volume of the West Antarctic Ice Sheet (WAIS). Examination of multibeam data revealed four acoustic facies that vary from west to east in a 900 km2 area. It is hypothesized that these facies, that formed nearly contemporaneously, are the r...

The Eastern Basin within the Ross Sea records changes in the volume of the West Antarctic Ice Sheet (WAIS).
