Exploring the Deep Reef – Red Sea

Dr Pim Bongaerts of The University of Queensland heads up the Deep Reef Science for the Catlin Seaview Survey. Very little is known about these deep reefs (aka the mesophotic zone), which can extend to depths over 100m+ beneath the ocean surface, but still harbour light-dependent coral communities. Using custom breathing gases and specialised equipment, Dr Bongaerts and fellow mesophotic scientists from the Interuniversity Institute for Marine Sciences and the California Academy of Sciences reveal this hidden world of the “twilight zone”.
