GPS-equipped surveying javelins dropped in Antarctica

UK: The British Antarctic Survey (BAS) has built advanced surveying equipment into javelin-like projectiles that they intend to drop into some of the most inaccessible parts of Antarctica in order to accurately measure the continent. The BAS has assembled 25 of the pieces of the equipment in order to track the progress of the Pine Island Glacier (PIG), one of the largest and fastest-moving ice streams on Antarctica. The hardy javelins contain advanced GPS equipment that will allow the BAS to monitor the speed and nature of the ice movement.

The darts are being dropped from aircraft flying over the region, and are equipped with parachutes and small ‘ice brake’ fins to lessen the force of their impact with the ice and stop them from driving too deeply.
