Wildlife Conservation Society and partners document large-scale coral bleaching and death in wake of sea surface temperature rise The Wildlife Conservation Society today released initial field observations that indicate that a dramatic rise in the surface temperature in Indonesian waters has resulted in a large-scale bleaching event that has devastated coral populations. WCS's Indonesia Program "Rapid Response Unit" of marine biologists was dispatched to investigate coral bleaching reported...

Cornell University researchers have found a new tool to help marine biologists better grasp the processes under the sea: They have created mathematical models to unveil the bacterial community dynamics behind afflictions that bleach and kill coral. (Public Library of Science "“ Biology, March 30, 2010.) Warming waters are triggering coral bleaching and disease in the Caribbean, Indian Ocean and Great Barrier Reef off the Australian coast. Now new mathematical models explain for the...

Penn State researchers and their international collaborators have discovered a diversity of corals harboring unusual species of symbiotic algae in the warm waters of the Andaman Sea in the northeastern Indian Ocean.  "The existence of so many novel coral symbioses thriving in a place that is too warm for most corals gives us hope that coral reefs and the ecosystems they support may persist "” at least in some places "” in the face of global warming," said the team's leader,...

The World Bank is a vital source of financial and technical assistance to developing countries around the world. At first glance, this may not appear to be connected to space technology, but large development projects and the state of Earth's environment are intrinsically linked. Global climate change is also an increasingly important challenge in overcoming poverty and advancing development in the poorest countries and communities, which will suffer the earliest and the most. These factors...

Scientists are reporting the first identification of substances involved in the Jekyll-and-Hyde transformation that changes harmless marine bacteria into killers that cause "coral bleaching." Their study appears in ACS' Environmental Science & Technology, a semi-monthly journal. Dan Bearden and colleagues note that bleaching already has destroyed up to 30 percent of the world's coral reefs, and scientists are searching for ways to slow or stop the damage. One known culprit is an...

To have even a chance of saving the world's coral reefs from extensive damage caused by global warming, carbon emissions in industrialized countries need to be cut by 25% below their year 2000 levels by 2020 "“ and by 80-90% by 2050. That is the uncompromising warning delivered today by some of Australia's most eminent marine and environmental scientists in a briefing to Australian Members of Parliament and Senators, in Parliament House, Canberra. "The Great Barrier Reef (GBR)...

Australian marine scientists have issued an urgent call for massive and rapid worldwide cuts in carbon emissions, deep enough to prevent atmospheric CO2 levels rising to 450 parts per million (ppm). In the lead up to United Nations Copenhagen Climate Change Conference Professors Charlie Veron (former Chief Scientist, Australian Institute of Marine Science) and Ove Hoegh-Guldberg of the ARC Centre of Excellence for Coral Reef Studies and The University of Queensland, have urged the world's...

Scientists said Thursday that lower-than-feared sea temperatures this summer gave a break to fragile coral reefs across the Caribbean and the central Gulf of Mexico that were damaged in recent years, the Associated Press reported. Many of the creatures that make up coral have had to expel the colorful algae they live with, creating a bleached color due to the unusually warm water in recent years. However, the coral itself will die and damage the environment where many fish and other marine...

With technology similar to that used by physicians to perform magnetic resonance imaging (MRI) scans, researchers from six institutions"”including the National Institute of Standards and Technology (NIST)"”working at the Hollings Marine Laboratory (HML) in Charleston, S.C., are studying the metabolic activity of a pathogen shown to cause coral bleaching, a serious threat to undersea reef ecosystems worldwide. Coral bleaching is the whitening of living coral due to a disruption of...

Disease can exacerbate coral bleaching, while bleaching leads to increased disease prevalence Mass coral bleaching has devastated coral colonies around the world for almost three decades. Now scientists have found that bleaching can make corals more susceptible to disease and, in turn, coral disease can exacerbate the negative effects of bleaching. A paper in the October issue of the journal Ecology shows that when they occur together, this combination of afflictions causes greater harm to...
