Google launches project to save coral reefs by crowdsourcing underwater sound recordings

The project aims to help improve the monitoring of marine wildlife activity, and also to help restore the reefs. The researchers have found that playing back sounds from healthy reefs using underwater speakers in damaged habitats can attract new fish and other underwater species to conserved reefs or those that have been damaged due to human activity. The team’s recordings were made at ten reefs located in countries including Australia, Indonesia, the Philippines, the US, Panama, and Sweden.
