Anchors aweigh for Boaty McBoatface!

The distinctively named long-range submarine is about to embark on its first mission to help research how climate change is affecting our oceans, British officials said Monday.

The unmanned sub will depart on Friday and traverse the vast Southern Ocean encircling Antarctica to study “some of the deepest and coldest abyssal ocean waters on Earth,” according to the Natural Environment Research Council.

Boaty McBoatface will dive more than 11,400 feet and measure ocean turbulence as part of the Dynamics of the Orkney Passage Outflow project.

One year ago, the unique moniker overwhelmingly won an online contest held by the NERC to name its new $290 million polar research ship.

But in a last-minute snub, the British government opted to name the massive, state-of-the-art ship, which has a more than 21,000-mile range, the Sir David Attenborough after the BBC naturalist.
