Audio: Haunting Sounds from the Deepest Parts of the Ocean

It’s not silent at the bottom of ocean. For three weeks, researchers from Oregon State University dropped a titanium-encased hydrophone at the bottom of the Mariana Trench in the Pacific, at a depth of 36,000, deeper than Mount Everest is tall.

It’s not silent at the bottom of ocean. 

For three weeks, researchers from Oregon State University dropped a titanium-encased hydrophone at the bottom of the Mariana Trench in the Pacific, at a depth of 36,000 feet, deeper than Mount Everest is tall. 

Instead of the peace and calm they expected, they heard a kaleidoscope of strange, haunting sounds, from whale calls to earthquake rumbles and typhoons. 

You would think that the deepest part of the ocean would be one of the quietest places on Earth.
