A yellow submarine dubbed Boaty McBoatface has obtained “unprecedented data” from its first voyage exploring one of the deepest and coldest ocean regions on Earth, scientists have said.

The robotic submersible was given the name originally chosen for a new polar research ship by irreverent contestants in a public competition. Embarrassed officials decided to ignore the popular vote and instead named the vessel the RRS Sir David Attenborough in honour of the veteran broadcaster. A storm of protest led to a compromise that allowed the name to live on.

The submarine plunged to depths as far as 4,000 metres to obtain information about temperature, water flow speed and turbulence from Orkney Passage, a region of the Southern Ocean about 500 miles from the Antarctic Peninsula.
