The discovery of the Terra Nova shipwreck

In 2012, a team of researchers discovered one of the most famous polar shipwrecks - the Terra Nova.

The ship was famous for carrying Britain’s doomed explorers in their race to reach the South Pole more than a century ago.

It was later sunk - laying unseen on the seabed for decades.

Oceanographer Leighton Rolley tells Megan Jones how he and the rest of his crew used sound waves to find the hidden wreck.
