Deep coral reefs at nine sites within the Great Barrier Reef are 40 percent bleached, while shallower reefs are up to 69 percent bleached due to a 2016 coral-bleaching event, according to a study published yesterday (September 4) in Nature Communications. Anywhere from 8 percent to 12 percent of shallow reefs and 6 percent of deep reefs are dead, indicating that no depth is safe from the effects of bleaching.
