A dense grid of ice-penetrating radar sections acquired over Pine Island Glacier, West Antarctica has revealed a network of sinuous subglacial channels, typically 500m to 3km wide, and up to 200m high, in the ice-shelf base. These subglacial channels develop while the ice is floating and result from...
