| MARIANA TRENCH ANIMAL |
Listen to the mysterious 'alien song' heard deep in the Mariana trench: Researchers reveal unexplained sound heard 36,000 feet down - That is 10,058 meters, or 10 kilometers, or 6.25 miles deep.
- The Mariana Trench is the deepest place in the world's oceans
- Scientists sent a hydrophone down to Challenger Deep, the deepest part
- Strange booming is unidentified - but it could be an animal call

| MARIANA TRENCH ANIMALS |
Researchers have released audio of a strange booming sound heard in the the deepest part of the ocean. Scientists at OSU's Hatfield Marine Science Center named it the 'Western Pacific Biotwang' and say their best guess is that it is a new type of previously unheard whale call.
Lasting between 2.5 and 3.5 seconds, the five-part call includes deep moans at frequencies as low as 38 hertz and a metallic finale that pushes as high as 8,000 hertz.
'It's very distinct, with all these crazy parts,' said Sharon Nieukirk, senior faculty research assistant in marine bioacoustics at Oregon State. 'The low-frequency moaning part is typical of baleen whales, and it's that kind of twangy sound that makes it really unique. We don't find many new baleen whale calls.'
