 This is scientific Americans, 60 second science, I'm Sarah Fecht. Got a minute


 
That’s not a bird whistling. This sound was recorded 2000 feet below the ocean’s surface.
 
Scientists postulated 1 decades ago that deep-sea animals
 
might use sound to navigate 2 and communicate. But until now, no one had really tried to listen in.
 
That’s why marine 3 ecologist Rodney Rountree, from the University of Massachusetts Amherst, decided 4 to turn a few mp3 players into waterproof 5, deep-sea recording 6 devices. He and his colleagues attached one device to each of 100 crab 7 traps, and sent them to the sea floor for 24 hours.
 
After dredging up the traps and listening to the recordings 8, the team discovered a multitude of deep-sea sounds, including 12 they could not identify and which had probably never been heard before. 
 
Rountree wants to send down video cameras along with the recording devices, in order to identify which species are making these strange sounds. Just like a birder uses his eyes and his ears to study bird species, Rountree hopes that eventually ecologists will be able to use sound to locate and learn more about marine species.
