Working on thinning ice: Custom-designed radar measures Antarctic ice with millimeter accuracy

This item was filled under Climate
A series of radars just deployed on Antarctica will give researchers their first ever day-by-day measurements of the health of one of the ice shelves that surround the frozen continent. The ice shelves around Antarctica can be up to 2 kilometres thick, but preliminary trials show the new radar system can detect changes of as little as a millimetre -- about the amount the Pine Island Glacier melts in just 30 minutes....
