Marine biologists from the University of Queensland is looking at coral reefs in Hawaii and what they see is not good. They used high resolution images to track coral bleaching and death. Recently coral reefs in Hawaii suffered their first known mass bleaching event, caused by unusually warm waters associated with the now famous “Blob”…
Coral reefs are oases of life in the oceans, harbouring more than a quarter of all marine species. These vibrant ecosystems are founded on reef structures that are built by the CaCO3 skeletons of “stony” scleractinian corals. While productive and biodiverse, coral reef ecosystems are sensitive to many elements of global environmental change, including “ocean […]
Park officials in the southern Australian province of Victoria say a deepwater reef has been discovered there that may have more coral, sponge, and fish than the Great Barrier Reef. Wilsons Promontory Marine National Park near Melbourne is the spot reef
Looks like one of the world's most famous natural wonders has some pretty impressive competition. This week, researchers in Australia announced the discovery of a coral reef with such diverse and thriving marine life, it rivals that of the Great Barrier Reef. Show More Summary
An American coral reef scientist found a small shrimp-like crustacean with a greatly enlarged appendage reminiscent of the Elton John character in the movie 'Tommy.' Discovered while working in the remote coral reefs of Raja Ampat, Indonesia, Dr. Show More Summary
On the coral reef, knowing who's your friend and who's your enemy can sometimes be a little complicated. Take seaweed, for instance. Normally it's the enemy of coral, secreting toxic chemicals, blocking the sunlight, and damaging coral with its rough surfaces. But when hordes of hungry crown-of-thorns sea stars invade the reef, everything changes, reports a new study.
Australia already has at least one of the natural wonders of the world in the Great Barrier Reef, but it may have just added another one more than 300 feet under the sea on the other side of the continent, Mashable reports. According to a Parks Victoria announcement yesterday, scientists...
Under attack from hordes of ravenous starfish, Pacific coral is getting help from an unexpected source — seaweed, an arch enemy, researchers said on Wednesday. Seaweed is no friend of the fragile ecosystems of coral reefs, pumping out harmful chemicals, blocking out life-giving sunlight, and...
The reef (Photo: Parks Victoria) Off the south coast of Australia, the Wilsons Promontory Marine National Park has been hiding an incredible coral reef beneath its waters. Not long ago, when scientists for the region's parks department...Show More Summary
Experts are beginning to wonder if we haven’t already exceeded the tipping point for life in the coral reefs. It is actually possible that living generations will never again experience the abundant coral reefs of only 50 years ago. Professor Peter F. Show More Summary
The longest-ever simulation of future ocean conditions, undertaken by researchers at Heriot-Watt, shows that the skeletons of deep-sea corals change shape and become 20-30% weaker, putting oases of deep-sea biodiversity at risk. Because the ocean absorbs much of the extra carbon dioxide produced by human activities, the chemistry of seawater is changing, a process known […]
Coral reefs are among the world’s richest ecosystems – and they will disappear from the face of the Earth before this century is over if we don’t make serious changes, ecologist Peter Sale told DW. DW: You talked about coral reefs at the Goldschmidt Conference in Prague. What is the future for reefs? What should […]
Application deadline: 6 September 2015! Changes in carbonate dissolution due to ocean acidification are potentially more important than changes in calcification to the future accretion and survival of coral reef ecosystems. Most carbonate in coral reefs is stored in old permeable sediments. Because these sediments are critical to the formation of the modern, shallow reef […]
Among the reasons to vacation in Fiji: coral reefs, traditional culture and elite private island resorts including a new one opening in September.
Even optimistic estimates for what might be achieved at December's Climate Change Conference in Paris will not be enough to save the world's coral reefs, according to experts.
We are losing coral reefs at an alarming rate and scientists believe that with business as usual they will likely be gone by the end of the century. However, better local management, coupled with new research on coral reef resilience and adaptability, may help buy some time for these indispensable ecosystems.
Coral reefs, as they were 50 years ago, will not be found anywhere on Earth by the middle of the century, an expert has warned. Professor Peter F Sale, from the University of Windsor, Canada, claims the world’s coral reefs cannot be saved – even if the climate change talks in Paris in December (COP21) […]
Turf algae are a very important component of coral reefs, featuring high growth and turnover rates, whilst covering large areas of substrate. As food for many organisms, turf algae have an important role in the ecosystem. Farming damselfish can modify the species composition and productivity of such algal assemblages, while defending them against intruders. Like […]
Scientists discover an area in the South Pacific where high levels of carbon dioxide have created dead zones where healthy coral reefs should be. In a remote area of the South Pacific, nature has opened a window on the most likely future for the world’s tropical coral reefs unless nations radically cut fossil fuel emissions. […]
