Submarine landform assemblage produced beneath the Dotson-Getz palaeo-ice stream, West Antarctica
Within Earth's ice sheets, fast-flowing ice streams are the principal components through which ice and sediment are discharged, accounting for c. 90% of the ice lost from the Antarctic today (Bamber et al. 2000). The processes occurring at ice-stream beds, therefore, lie at the heart of resolvi...
