Divers off Jamaica install solar-powered underwater speakers to replay healthy reef sounds for 14 hours daily, aiming to lure marine life back to degraded reefs; inspired by a Nature study showing acoustic enrichment can double fish numbers and boost biodiversity, the project blends art and science with lab-grown corals to counter climate-driven reef decline.
Researchers have found that playing recordings of healthy coral reef sounds through underwater speakers can attract coral larvae to struggling reefs, potentially aiding in their recovery. The study, conducted off the US Virgin Islands, showed that coral larvae were up to seven times more likely to settle at reefs where the sounds were played. While the results are promising, further research is needed to understand the long-term effects and ensure the survival and growth of the settled corals. This innovative approach offers hope for the restoration of damaged and degraded reefs in the face of significant threats such as global heating, overfishing, and pollution.
