When it comes to the ocean, its depths are oftentimes less explored than outer space.
“There’s a tremendous amount we don’t know,” UW oceanographer Kate Stafford said. “I mean, it’s just staggering.”
In an effort to bridge the gap, Stafford and others have been using what are called haruphones or hydrophones—single underwater microphones. These hydrophones are weighted down by an anchor and placed on the ocean floor.
