Boaty McBoatface is joining ocean scientists on an expedition to study some of the deepest and coldest abyssal ocean waters on earth – known as Antarctic Bottom Water (AABW) – and how they affect climate change. The team of researchers will assess water flow and underwater turbulence in the Orkney Passage, a region of the Southern Ocean around 3,500m deep and roughly 500 miles from the Antarctic Peninsula. They will use one of the Autosub Long Range class of unmanned submersibles, the latest type of autonomous underwater vehicle (AUV), now known as Boaty McBoatface, following last year’s campaign to name the UK’s new polar research ship.
