Recording Deep Ocean Fish Sounds (IMAGE) University of Massachusetts Amherst Caption Fisherman Juan Espana aboard the F/V Hanna Boden, Gloucester, prepares to deploy a deep-sea sound recorder (the fluorescent green ball) inside the crab trap under his left hand. UMass Amherst researchers analyzed data from the recorder, which Espana and crew recovered with their gear after 24 hours it spent on the ocean floor, to study deep-ocean fish sounds.
