Whales are being killed by noise pollution, but this device might help.


Animals in the ocean, where light can only travel a few hundred feet below the surface

However, until very recently, people were ignorant of the underwater soundscape.

Whales, which rely on sound to navigate, can become confused by the noise from ship engines.
