Millions of years ago, one area of reefs managed to survive a major coral extinction.

The Coral Triangle in the Western Pacific is still the most biodiverse region in the world. And that is why leading marine scientists are deploying the latest in 3D mapping technology to uncover the secrets of what allowed the coral in this unique area to survive.

But it is a race against time.

Seventy-five percent of reefs globally are under threat due to climate change, pollution and destructive fishing practices.
