The deepest part of the ocean lies in the Mariana Trench near Micronesia. It is dark, mysterious abyss that few of us will ever see. But now we can hear what it sounds like, thanks to a new study from researchers at the National Oceanic and Atmospheric Administration (NOAA), Oregon State University and the U.S. Coast Guard.
The researchers used a titanium-encased hydrophone to record ambient noise for three straight weeks in July 2015, and what they heard was nothing like what one might expect from a region long thought to be inhospitable to most large marine mammals.
