The deepest part of the ocean -- the Mariana Trench -- is proving to be eerily noisy.

Scientists recorded ambient noise for three weeks from a hydrophone placed 36,000 feet below the ocean surface in the Challenger Deep trough in the Mariana Trench near Micronesia. What they discovered was the deepest part of the ocean is not a place of peace and solitude but instead has a cacophony of sounds.

 

"You would think that the deepest part of the ocean would be one of the quietest places on Earth," Robert Dziak, a research oceanographer with the National Oceanic and Atmospheric Administration, said in a statement this week.

 

"Yet there is almost constant noise," he added. "The ambient sound field is dominated by the sound of earthquakes, both near and far, as well as distinct moans of baleen whales, ships, and the clamor of a category 4 typhoon that just happened to pass overhead."

Eerie

 

Does make some sense though.

 

Think the trench itself it the meeting point of two tectonic plates being pushed together which must generate noise.

 

Also the trench is walled so its logical that a lot more reverberation would be heard from sound bouncing back of the walls of the trench.

 

Still one of the coolest places on Earth though

I think i read somewhere that we've explored a smaller percentage of the deep sea than the moon.  Every time they go below a few thousand metres they discover new species.  Who knows what's down there?  Must be awesome to work in oceanography.

Yeah that is true...

 

I'd rather have a million camera's down there instead of a Mic.

Sounds like a good reason for film producers to make the film Deep Blue Sea 2
