Researchers hope to breed Great Barrier Reef corals more resilient to extreme heat events – video

Researchers from the Australian Institute of Marine Science are hoping to breed corals that are more resilient to extreme heat events. The researchers collected hundreds of coral samples from the northern part of the Great Barrier Reef that have survived three mass bleaching events since 2016. The samples have to be collected before they spawn which occurs only once a year, several days after a full moon in spring. They then hope to breed these samples with corals from the southern part of the reef which are less heat tolerant
