A small yellow robot submarine, called Boaty McBoatface after a competition to name a new polar research ship backfired, is being sent on its first Antarctic mission.
Boaty, which has arguably one of the most famous names in recent maritime history, is a new type of autonomous underwater vehicle (AUV), which will be able to travel under ice, reach depths of 6,000 metres, and transmit the data it collects to researchers via a radio link.
Its mission will be to investigate water flow and turbulence in the dark depths of the Orkney Passage, a 3.5km deep region of the Southern Ocean. The data it collects will help scientists understand how the ocean is responding to global warming.
The name it was given came in the wake of a campaign by the Natural Environment Research Council (NERC) that asked members of the public to suggest names for its new polar research ship.
