Boaty McBoatface minisub sent on first Antarctic mission

An unmanned submersible christened Boaty McBoatface after a competition to name a new polar research ship backfired is being sent on its first Antarctic mission.

Boaty, a new type of autonomous underwater vehicle (AUV), is to investigate water flow and turbulence in the dark depths of the Orkney Passage, a 3.5 kilometre (2.17 miles) deep region of the Southern Ocean.
