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, say scientists.
The robotic submersible was given the name originally chosen last year for a new polar research ship by irreverent contestants in a public competition.
A storm of protest on Twitter led to a compromise that allowed the Boaty McBoatface name to live on.
Boaty dived to depths of up to 4,000 metres to obtain information about temperature, water flow speed and turbulence from Orkney Passage, a region of the Southern Ocean some 500 miles from the Antarctic Peninsula.
The data will help scientists to understand the complex way mixing ocean waters affect climate change.
Professor Alberto Naveira Garabato, from the University of Southampton, said: “The Orkney Passage is a key chokepoint to the flow of abyssal waters in which we expect the mechanism linking changing winds to abyssal water warming to operate.
“Our …
