Summary We use basal roughness, a property accessible to airborne ice penetrating radar, to examine the dynamics of the West Antarctic Ice Sheet. We examine roughness through analysis of the along track variability of basal elevation profiles collected over the Siple Coast and the Thwaites Glacier c...
