Scientists are using underwater speakers to help restore degraded coral reefs: Study (ABC)
Researchers have discovered a new method that could encourage the restoration of degraded coral reef populations, which have been declining around the world due to record-high marine temperatures.
The sounds of a healthy reef could be used to encourage coral larvae to recolonize damaged or degraded reefs, according to a study published in the journal Royal Society Open Science on Tuesday. Underwater speakers that play the sounds of a healthy reef, such as fish calls, were found to help coral larvae settle at rates up to seven times higher.
