This recording from the deepest part of the ocean is the scariest thing we’ve ever heard

Just when you thought it was safe to go to the deepest part of the ocean…it isn’t. It’s really hard, don’t go there. But if you did get to Challenger Deep in the Mariana Trench, thought to be one of the deepest parts of the ocean, what you heard might scare your waterproof socks off.

Oceanographer Bob Dizak and his team from the National Oceanic and Atmospheric Administration (NOAA), recently decided they were low on tunes and needed a new playlist. So they designed an audio-recording instrument capable of withstanding pressure 36,000 feet underwater at Challenger Deep, and like we used to with our favorite radio stations, hit “record” for 23 days of non-stop ocean sounds.

What did they hear down there? Actually quite a lot.
