Robo-sub takes Antarctic plunge


Saiba+ BBC NEWS



"A voyage to Antarctica's icy depths has revealed a rich array of marine life and geological features that may shed light on the region's past and future.

Isis, the UK's first deep-sea remote operated vehicle, combed the area's sea bed, diving down to 3.5km (two miles).

The vessel imaged diverse animals, such as king crabs, anemones and sponges.

It also gave the first view of ancient 'meltwater channels', which will aid understanding of how the Antarctic ice sheet might change in the years ahead."
