Science 'javelins' spear Antarctic
UK scientists have developed an air-dropped projectile to put instruments in some of the most inaccessible places in Antarctica.
Twenty-five of these "javelins" are currently sticking in Pine Island Glacier, one of the continent's biggest and fastest-moving ice streams, monitoring its movement.
Dr David Jones from the British Antarctic Survey described the design of javelins to our science correspondent Jonathan Amos.
