Boaty McBoatface returns home from abyss

Researchers have captured unprecedented data about some of the coldest abyssal ocean waters on earth – known as Antarctic Bottom Water (AABW) – during first voyage of the yellow robotic submersible known as Boaty McBoatface, which arrived back in the UK last week. The team captured data on temperature, speed of water flow and underwater turbulence rates of the Orkney Passage, a region of the Southern Ocean which is around 4,000m deep and roughly 500 miles from the Antarctic Peninsula.
