Google wants you to listen to coral reefs. It just might help restore them.

Google wants your help in preserving and restoring coral reefs, and has designed a platform to help with this mission in mere minutes. All you have to do is tune in. Called "Calling in Our Corals"(opens in a new tab), the new citizen science project is a collaboration between Google Arts and Culture and marine biologists across the globe. People are being asked to listen to underwater recordings of coral reefs in Marine Protected Areas through an online platform, identifying sounds made by fish, shrimp, and other marine creatures in order to monitor ecosystems and determine opportunities for reef restoration. Scientists have placed hydrophones in 10 reefs across Australia, Indonesia, Philippines, the U.S., Panama, and Sweden, which record 24 hours a day, meaning there's hundreds of hours to sift through.
