Soundtrack of the sea: divers use underwater speakers to help dying coral reefs

A team led by Italian artist Marco Barotti is installing solar-powered underwater speakers near Jamaica's northern coast to play sounds of healthy coral reefs, part of the Alligator Head Foundation's efforts to revive dying reefs. This acoustic enrichment strategy, backed by research showing it doubles fish populations and boosts species diversity in degraded areas, is combined with lab-grown coral fragments and assisted breeding to restore ecosystems impacted by climate change, pollution, and overfishing.
