Great Barrier Reef: UNESCO Recommends World Heritage Site Not be Placed on ‘In Danger’ List

World’s largest coral reef to remain on UN’s watchlist as draft ruling calls on Australia to ‘rigorously’ implement its conservation commitments. Environmental groups consider the reef – regardless of the Unesco ruling in June – technically in danger.

Land Bridge Linking Americas Rose Earlier Than Thought

There’s new geologic evidence that the narrow Panama land bridge emerged from the sea 12 million to 15 million years ago, much earlier than thought. This early uplift wreaks havoc with prevailing ideas, which suggest this strip of land established itself just 3 million years ago.

Ocean-scale Dataset Allows Broad View of Human Influence on Pacific Coral Reef

A study draws on data from nearly 40 islands and atolls across the central and western Pacific, including 25 unpopulated islands, to investigate the relative influence of environmental variation and human presence on reef fish assemblages. The resulting message is sobering.

Despite Protections, Miami Port Project Smothers Coral Reef in Silt

The government divers who plunged into the bay near the Port of Miami surfaced with bad news again and again: Large numbers of corals were either dead or dying, suffocated by sediment. The source of the sediment, environmentalists say, is a $205 million dredging project…

Along Cuba’s Coast, The Last Best Coral Reef in the Caribbean Thrives

While coral reef cover has declined by 50 percent throughout the Caribbean, Cuba has managed to retain some of the most pristine coral reef environments on earth. Lack of coastal development, limited tourism, small amounts of runoff flowing into the sea, tight controls on commercial fishing, and the establishment of extensive marine protected areas have all combined to give Cuba the most remarkable coral reef environments in the Caribbean.

Study Projects Unprecedented Loss of Corals in Great Barrier Reef Due to Warming

The coverage of living corals on Australia’s Great Barrier Reef could decline to less than 10 percent if ocean warming continues, according to a new study that explores the short- and long-term consequences of environmental changes to the reef.

Hidden Battles on the Reefs

How do you drown a coral reef? The very idea seems unfathomable for animals that spend their entire lives under water. But the deep ocean is actually riddled with “drowned” coral reefs, the remains of ancient reefs that slipped into the dark ocean depths and starved without sunlight.

Coral Reefs Threatened by Changing Ocean Conditions

Erosion rates increase tenfold in areas where corals are also exposed to high levels of nutrients, according to a study published January 2015 in the journal Geology. As sea level rises, these reefs may have a harder time growing toward the ocean surface, where they get sunlight they need to survive.
