Deepwater corals may be key to restoring damaged reefs, survey finds
Healthy corals that lie deep below the ocean's surface may be the key to regenerating parts of Australia's badly damaged Great Barrier Reef, according to an underwater survey being carried out off the coast of northern Queensland.
Using remote operated vehicles (ROVs) and deep-sea diving techniques, the Catlin Seaview Survey has found healthy coral habitats at depths of 30-120 metres, right underneath badly damaged areas of the Great Barrier Reef.
