Get more in-depth details about our research into reefs past and present. Coral reefs are threatened by overfishing, pollution, invasive species and ocean warming and acidification caused by rising carbon dioxide levels. Even after the Keys reefs stopped growing upward, they supported diverse communities of marine life, protected the island chain from storm waves and erosion, and provided other ecosystem functions for thousands of years. Making up the bulk of the rocks collected were fossils of coral reef ecosystems that revealed just how different undersea life was 12 million years ago. But according to a recent study, in the past three decades, the reef has lost almost half of its coral population. 1 INTRODUCTION. âIn the next century, maybe all coral reef researchers will be palaeontologists,' he says. More than one-third of the reefs have not grown at all in the past 3000 years, and the rest have not kept up with rising sea level. Glimpse some of the beautiful coral specimens in our collection and explore why coral diversity is important.

The past two decades have seen several incidents of widespread coral bleaching events on many of the world’s coral reefs.. Reefs in Western Australia's Rowley Shoals "dodge a bullet" by making a remarkable recovery from coral bleaching — but scientists fear the long-term outlook might not be so pretty.

Although reefs were no longer growing, there was enough living coral to prevent them from eroding,” Toth said. (CNN) — Australia's Great Barrier Reef has lost 50% of its coral populations in the last three decades, with climate change a key driver of reef disturbance, a new study has found. They are most often found in … The new fossil corals from Borneo have added significant ancient material to the collection, and a huge donation of modern corals from the Chagos Islands in the Indian Ocean will also help us to understand the largest coral atoll in the world - one of the last pristine coral habitats. They are easy prey for fish that can chomp their way through corals and they are susceptible to diseases and coral bleaching - the loss of their symbiotic algae that help provide them with energy.
