Scientists find deepest part of ocean is full of eerie noises
What does the deepest part of the ocean sound like?
It isn't as quiet as many would think, says Robert Dziak, an oceanographer with National Oceanic and Atmospheric Administration.

In fact, he says in a press release, "...there is almost constant noise."
He explains that the sources of noise include earthquakes, baleen whales, ship propellers, and weather-related events like a typhoon.
This is what he and a team of researchers found when they recorded sound within the Mariana Trench, the deepest known area in all the oceans, for about three weeks.
Located in the western Pacific Ocean, it reaches depths exceeding 36,000 feet, or about 7 miles.
The main difficulty they encountered was getting the hydrophone, or underwater recorder, to the seafloor because of the extreme atmospheric pressure.
