Australia's unexplored deep reefs —
The Catilin Seaview Survey discovered healthy coral populations at depths below 30 meters on the Great Barrier Reef.

Thriving in the deep —
These healthy deep reefs are located directly under shallow reefs degraded by storms and other stresses including coral bleaching and invasive crown-of-thorns starfish plagues. The deep coral is often flat because of the lack of light at depth.

Roving submersibles —
Remote operated vehicles (ROVs) were used to get to depths of around 100 meters, much deeper than normal scuba divers are able to go.

Coral survey —
"At the moment we know little about the extent of larval movements between the shallow and deep reef, but we are seeing species that exist in both zones," said Pim Bongaerts.
