West Antarcticas ground is almost entirely below sea level. A tunnel was driven into the sloping surface of the ice towards a crevasse about a foot wide. The new map, called BedMachine Antarctica, shows, for example, previously unrecognised ridges that will impede the retreat of melting glaciers in a warming world; and, alternatively, a number of smooth, sloping terrains that could accelerate withdrawals. This was the first deep crevasse, just 25 miles from Shackleton. AFP // Getty . It worries scientists because it sits on a bed that slopes back towards the land - a geometry that tends to assist thinning and withdrawal.
