Improvements in the resolution of seafloor mapping techniques have revealed extremely regular, sub-meter scale ridge landforms produced by the tidal flexure of ice-shelf grounding lines as they retreated very rapidly (i.e., at rates of several kilometres per year). Guided by such novel seafloor obse...
