UK scientists to probe Pine Island Glacier

9 September 2013 Last updated at 15:47 BST

A group of scientists are about to embark on a mission to one the remotest places on earth - the Pine Island Glacier in Antarctica.

The glacier drains about 10% of all the ice sliding off the west of the continent, and has seen a marked thinning and a surge in velocity in recent decades.

The British Antarctic Survey wants to understand what is causing the changes, and will be employing a number of unusual techniques to do so.
