Soundscapes Boost Coral Reef Restoration Efforts

Playing healthy reef sounds significantly increases coral larvae settlement on damaged reefs, offering a new tool for marine conservation.

Research by the Woods Hole Oceanographic Institution shows that playing sounds from healthy reefs can significantly increase coral larvae settlement on degraded reefs.
The study conducted in the U.S. Virgin Islands found that coral larvae settlement rates were up to 7 times higher near speakers broadcasting healthy reef sounds.
This method could serve as a scalable and relatively simple tool for coral reef restoration, potentially aiding in the recovery of ecosystems that support a quarter of all marine life.
Despite the success at degraded reefs, the researchers noted a possible decline in settlement rates at previously healthier reefs, highlighting the urgent need for effective restoration strategies.
The research was supported by the Vere and Oceankind Foundations and the National Science Foundation, emphasizing the global importance of coral reef conservation.
