New Study: Sounds Can Help Revive Coral Reefs

You could leave a speaker out for a certain amount of time and it could be attracting not just coral larvae but fish back to the reef.

Nadège Aoki with the Woods Hole Oceanographic Institution in Massachusetts, who helped lead a recent study indicating that underwater speakers broadcasting sounds of thriving coral reefs could help bring life back to damaged coral reefs.

Why It Matters: Researchers found that playing sounds of a healthy coral reef ecosystem made coral larvae (an essential component of blossoming coral reefs) “up to seven times more likely to settle at a struggling reef.” As half of the world’s coral reefs have died since the 1950s, this research offers hope for developing more resilient underwater ecosystems.
