Coral reefs are surprisingly noisy places, but when they are degraded, they become "ghostly quiet." The lack of noise deters fish populations from settling in the dying reef, scientists say, further contributing to the decline.

In an effort to return life to the many reefs ravaged by climate change, researchers from the U.K. and Australia installed underwater speakers in a section of Australia's Great Barrier Reef. They projected the sounds of a healthy reef into a dying one, and diverse fish species from across the food chain flocked to the noise.
