Guest: Dr. Aran Mooney

When you think about saving coral reefs, you probably imagine divers, coral nurseries, or maybe even futuristic technology — but what if part of the solution starts with simply turning up the volume? Because it turns out, coral reefs don’t just look alive… they sound alive. Today’s guest, Dr. Aran Mooney, is helping scientists and conservationists tune into the ocean in a whole new way. His research explores how the natural “music” of healthy reefs — the pops, clicks, and choruses of marine life — can actually help guide coral larvae home and jump-start reef recovery. In this episode, we’ll talk about listening to the ocean, using sound as a conservation tool, and why sometimes the key to protecting our planet isn’t louder warnings — it’s learning how to hear what nature has been telling us all along.
