Bleaching killed 34 percent of the island’s reefs between 2013 and 2017, a study finds.

Runoff and waste may be more harmful to the animals than climate change.

Gates was director of the Hawaii Institute of Marine Biology and a strong advocate for coral conservation.

Both deep and shallow reefs are prone to bleaching, concludes a new study.

Historically thought to be a refuge for coral growing in the shallows, coral reefs from oceanic depths face similar threats, finds a new study.

The reef has bounced back from “death events” in the past, but that doesn’t mean it will be resilient over the next few decades.

Not only did many corals die in recent years, but some were actually killed by the hotter temperatures themselves, rather than bleaching.

Researchers exposed a coral reef to carbonated water to study the effects of ocean acidification.

Mary Hagedorn is racing to save Earth’s coral reefs by developing techniques for freezing the colonial animals’ gametes.
