Sounds of Survival: How Art and Science Are Reviving Coral Reefs
Harnessing sound to restore marine ecosystems—how an innovative project is merging acoustic ecology, 3D printed sculptures, and solar power to breathe new life into coral reefs
The ocean is alive with sound. In thriving coral reefs, a symphony of crackling shrimp, fish chatter, and other natural noises create an underwater world rich with life. But when reefs die, so too does their soundscape. Coral Sonic Resilience, an interdisciplinary project led by artist Marco Barotti, seeks to restore these vital ecosystems using the power of sound.
The Science of Sound and Reef Recovery
Marine biologists have discovered that healthy reefs generate distinct acoustic signatures, which act as natural beacons for marine life. Fish larvae and other organisms are instinctively drawn to these sounds, repopulating areas where marine ecosystems have declined. By replicating these soundscapes, scientists can actively encourage marine regeneration.
Coral Sonic Resilience builds on this insight, installing sound-emitting sculptures in damaged reefs and coral nurseries. These sculptures play pre-recorded reef sounds on a continuous loop, helping to attract marine life back to struggling ecosystems.
Art Meets Ecology: The Sound Sculptures
More than just acoustic tools, these submerged sculptures are also works of art. The sculptures’ shapes are inspired by coral landscapes and the textures of brain corals, they are 3D-printed from ceramics and calcium carbonate, materials that provide an ideal substrate for coral growth. Over time, marine organisms can colonize these structures, making them both a habitat and an active agent of restoration.
Powering the installation is an innovative solar buoy station, designed to operate entirely off-grid. This floating power source ensures that the soundscapes play uninterrupted, providing a long-term intervention for reef conservation.
From Ocean Depths to Global Awareness
Beyond its direct environmental impact, Coral Sonic Resilience is also an artistic endeavor designed to raise awareness about marine conservation. The project will evolve into an immersive exhibition, bringing the experience of underwater soundscapes to audiences around the world. By blending scientific research with artistic expression, the initiative fosters a deeper connection between humans and marine ecosystems, inspiring action against ocean degradation.
The first prototypes of the sound sculptures were deployed in December 2024 around Feridhoo Island in the Maldives. Scientists and researchers have been collecting acoustic data from healthy reefs to refine the project’s soundscape recordings. The team is also testing the durability of materials, anchoring systems, and solar technology ahead of a full-scale deployment set for August 2025.
This ambitious project is a collaborative effort involving marine biologists, sound engineers, and designers. With the support of the BCA at the University of Padua, Relaxound, the Coral Restoration Project Feridhoo and the Feridhoo Island Council, the initiative is breaking new ground at the intersection of art, science, and sustainability.
