Underwater robot sheds new light on Antarctic Ice

The first ever 3D map of the underside of the Antarctic sea ice has been created with the help of scientists based in Cambridge.

Experts at the British Antarctic Survey used a robotic submarine to scan the ice from below, giving them a far more detailed picture than they've ever had before.

The robotic sub known as SeaBED scans the sea ice around the South Pole.

Experts from Cambridge worked alongside colleagues from Australia and America. Their results have now been published in the journal Nature Geoscience.
