Down into the ocean's 'twilight zone' with Boaty McBoatface

[Still Waters]

Battling choppy waves and high winds, three engineers pulled ashore a yellow submarine in Scotland this week.

With sheets of water pouring from its body, the UK’s most famous robot - Boaty McBoatface - was winched up after 55 days at sea.

“It’s a bit slimy, and ocean smells have seeped in. There’s a few things growing on it,” says Rob Templeton, now dismantling the 3.6m robot in Leverburgh, on the Isle of Harris.

Boaty has completed a more-than-2,000km scientific odyssey from Iceland that could change what we know about the pace of climate change.

It was hunting for marine snow - “poo, basically” in the words of one researcher. This refers to tiny particles that sink to the ocean floor, storing huge amounts of carbon.
