Planes will this week cover areas in the southern half of the reef that escaped earlier bleaching but may have undergone high levels of heat stress
The full impact of coral bleaching across the Great Barrier Reef will become clearer this week as aerial surveys of hundreds of reefs are completed in the bottom two thirds of the world’s biggest reef system.
An aerial survey carried out last week over almost 500 individual reefs between the Torres Strait and Cairns revealed some severe bleaching of corals closer to shore, but almost none on outer reefs.
Day 4: We have now completed assessment of #coral bleaching between Cairns and northern Torres Strait.
Today, we saw extreme levels of bleaching on coastal reefs from Lockhart River to Cairns. Mid-shelf reefs in this region have variable levels of bleaching, from mild to severe pic.twitter.com/QdN16S0cV3
Aerial surveys this week of the Ribbon Reefs, above Cairns, show little to no bleaching. Aerial surveys continue over the coming days in areas that experienced more heat stress. #GreatBarrierReef #video pic.twitter.com/4cdjpbj4ZE
