The Great Barrier Reef in Queensland has suffered several mass bleaching events due to the impacts of climate change. The Australian government turned down a proposal for a new open-cut coal mine near the Great Barrier Reef, considering environmental laws and the risk of"irreversible damage”. It...

Severe coral bleaching events have affected the Great Barrier Reef (GBR) causing massive losses of hard coral cover. Here, we use flow respirometry approaches to assess coral reef net ecosystem calcification (NEC) and net ecosystem production (NEP) following the 2015/2016 bleaching event at ...
One quarter of the Great Barrier Reef suffered severe bleaching(漂白) this summer in the most widespread outbreak ever witnessed, according to analysis of aerial(天线)surveys of more than 1 ,000 individual reefs released on Tuesday.Dr David Wachenfeld, chief scientist at the Great Barrier Reef ...
“Our combined 2016 and 2017 surveys show that two-thirds of the Great Barrier Reef has now been badly degraded,” says Hughes. It is a loss that under normal circumstances would take a decade to recover from. “But now that bleaching is happening every year or every other year i...
Unprecedented coral bleaching in consecutive years has damaged two-thirds of Australia's Great Barrier Reef, aerial surveys have shown. 航空勘测发现,近年连续发生的珊瑚白化问题空前严重,澳大利亚三分之二的大堡礁已遭到重创。 The bleaching - or loss of algae - affects a 1,500km (932 miles) area of...
“This will change the Great Barrier Reef for ever,” Terry Hughes, an expert on coral reefs from James Cook University, told the Australian Broadcasting Corp. “We’re seeing huge levels of bleaching in the northern thousand kilometer stretch of the Great Barrier Reef.” ...
Deep (or “mesophotic”) coral reefs are hypothesised to act as major ecological refuges from mass bleaching, but empirical assessments are limited. We evaluated the potential of mesophotic reefs within the Great Barrier Reef (GBR) and adjacent Coral Sea to act as thermal refuges by ...
Hughes said he took about 11 flights over nine days in March criss-crossing the full length of the Great Barrier Reef, surveying 1,036 reefs from the air to measure the extent and severity of the coral bleaching. What he saw was unprecedented. “For the first time, severe bleaching has s...
