Coral reefs: a biological symphony being silenced

May 23, 2022

To most of us, coral reefs conjure up magical places full of colorful species and life. They are unknown and otherworldly. Their beauty is perhaps a reason why coral reefs have become one of the more famous victims of climate change, warming oceans. Most people have heard that the future for coral reefs is in total jeopardy. 

And this is a problem, because about 25% of the ocean’s fish depend on healthy coral reefs. Scientists are now warning that the Great Barrier Reef could be gone by the year 2050 if nothing is done to help it.

And it turns out….. Reefs are noisy places. Fish, shrimp, all the little creatures that call a reef home add to the sonic palette of the place.

But as reefs become more unhealthy…life on them is becoming harder for Tim to hear.

The sounds of these watery ecosystems are becoming a very important tool for researchers like Tim. And he has an idea that might be key to helping these struggling coral reef ecosystems rebound. Armed with a microphone and an underwater speaker….can the power of audio help save coral reefs?

Hiro’a is part of a multimedia art project called Small Island Big Song. It is a grassroots musical movement from 16 island nations across the Pacific and Indian Oceans focusing on environmental and climate awareness and cultural preservation.
