The Great Barrier Reef Marine Park Authority has begun the second phase of its in-water surveys to assess the impact of this year's mass coral bleaching event. The second phase, which began on 5 October 2016, will assess survival rates and the extent to which corals have recovered across the Marine Park.

The preliminary findings show 22 per cent of coral on the Reef died due to the worst mass bleaching event on record. Eighty-five per cent of this mortality occurred in the 600 kilometre stretch between the tip of Cape York and just north of Lizard Island. Click here for the first phase interim report.

Corals are able to cope in a limited temperature range and when the temperature exceeds this limit, they experience heat stress. Most corals have microscopic marine algae (called zooxanthellae) living inside their tissue — these give corals much of their colour and food. When corals are under stress, this symbiotic relationship breaks down, and corals expel the zooxanthellae. Without zooxanthellae, the coral’s tissue becomes transparent and the coral’s bright white skeleton is revealed. If the stress is prolonged, bleached corals begin to starve without zooxanthellae and eventually die. The remaining coral skeletons are then colonised by algae, restricting the ability of baby corals (carried by currents) to establish themselves on these sites.
