Great Barrier Reef: Bleaching 'kills 35% of area's coral'

BBC: At least 35% of corals in the northern and central parts of Australia's Great Barrier Reef have been destroyed by bleaching, Australian scientists say. The experts from James Cook University (JCU) say it is the most extreme case of mass bleaching they have ever measured at the World Heritage Site. Bleaching occurs when warmer water causes coral to weaken and lose the colourful algae that provide oxygen and nutrients. It has been linked to climate change. "We found on average, that 35%...

Australia: Bleaching May Have Killed Half the Coral on the Northern Great Barrier Reef, Scientists Say
2016-05-29 22:00:00| Climate Ark Climate Change & Global Warming Newsfeed
New York Times: Mass bleaching on the Great Barrier Reef in the past three months has killed as much as half of the coral in the north but left large parts of the southern reaches with only minor damage, scientists in Australia said on Sunday. The current bleaching is the third to strike the roughly 1,400-mile-long reef in 18 years and the most extreme scientists have recorded. In the north, the mortality rates are off the scale, said Prof. Terry Hughes, the director of the ARC Center of Excellence for Coral...

Most coral dead in central section of Great Barrier Reef, surveys reveal

Guardian: The majority of coral is now dead on many reefs in the central section of the Great Barrier Reef, according to an underwater survey of 84 reefs, in the worst mass bleaching event to hit the world heritage site. An average of 35% of coral was now dead or dying in the northern and central sections, according to the surveys led by the Australian Research Councils Centre of Excellence for Coral Reef Studies. But in good news for tourists and the tourism industry, only 5% of coral has died on reefs...

A whole new ballgame: 35% coral death in parts of Great Barrier Reef
2016-05-29 15:47:00| Climate Ark Climate Change & Global Warming Newsfeed
Post: We knew this was coming. For months, coral reef experts have been loudly, and sometimes mournfully, announcing that much of the treasured Great Barrier Reef has been hit by severe coral bleaching, thanks to abnormally warm ocean waters. Bleaching, though, isnt the same as coral death. When symbiotic algae leave corals bodies and the animals then turn white or bleach, they can still bounce back if environmental conditions improve. The Great Barrier Reef has seen major bleaching in some...

Mother Nature Network: To rebuild coral reefs quickly, just add electricity Biorock reefs -- sunken steel frames connected to a low-voltage current -- are giving coral a second chance at surviving humanity You may have heard that coral reefs are in trouble. Serious trouble. A recent survey of Australia's Great Barrier Reef, the largest living structure on the planet, found 93 percent of the coral has been impacted by bleaching; a stark warning sign that the ecosystem is under tremendous environmental stresses. The...
