50 Reefs Initiative Is Good News For Coral Reefs

Coral reefs are in crisis. The facts are clear: without a different approach to conservation, coral reefs will continue to decline toward extinction. However, an announcement last week in Bali, Indonesia gave us some new reasons to be hopeful.
Cost-effective solutions to sediment runoff and other land-based pollution affecting West Maui reefs

Land-based pollutants have been linked to the degradation of several Hawaiian reefs. Between 2000 and 2015, coral cover on West Maui’s northern reefs has dramatically declined from 30 percent to 10 percent.
Huge Undersea Landslide Slammed Great Barrier Reef 300,000 Years Ago

More than 300,000 years ago, a colossal undersea landslide sent huge amounts of debris sliding down the Great Barrier Reef, generating a 90-foot-high (27 meters) tsunami, researchers have discovered.
Threat of poisonous algae growing on Great Barrier Reef

The future of the Great Barrier Reef looks increasingly precarious. Researchers in Australia have identified a new threat — not bleaching, but encroaching algae.
Japan’s Largest Coral Reef Is Dying

More than 90 percent of the corals in Sekiseishoko reef, located in the Ryukyu Islands near Okinawa, were discovered to be at least partially bleached when surveyed in November and December. About 70 percent of the reef’s living corals were found to have died.
Video Captures the Violent Act of Coral Bleaching

The video revealed for the first time how the mushroom coral Heliofungia actiniformis, which is a single polyp, physically reacts to heat stress. The results gave scientists more information about how corals will respond to warming seas that are associated with climate change.
A New View of Coral Reefs; Video

NASA’s Coral Reef Airborne Laboratory (CORAL) has studied the Great Barrier Reef off the coast of Australia and has several other targets planned.
Great Barrier Reef suffered worst bleaching on record in 2016

Higher water temperatures in 2016 caused the worst destruction of corals ever recorded on Australia’s Great Barrier Reef, a study has found.
Can killer robots save ocean ecosystems?

Few predators can match the devastating impact of the lion fish. Since arriving in US waters in the 1980s, these fearsome creatures have left a trail of destruction along the Atlantic Coast, from Rhode Island to Venezuela. Lionfish can reduce a flourishing coral reef to barren wasteland in a matter of weeks.
