By Robert Nolin & Rafael A. Olmeda, South Florida Sun-Sentinel Jul. 7--When it comes to the health of South Florida's coral reefs, the prognosis is not as gloomy as it could be. But it's not that sunny, either. Coral reefs stretching from the Keys to Martin County haven't deteriorated over the past five years, government scientists say. But that may be because damage inflicted over decades by storms, pollution, sewage and warmer temperatures has already been done. "Coral generally...

Scientists said nearly half of all coral reef ecosystems under U.S. jurisdiction are in poor or fair condition. The National Oceanic and Atmospheric Administration said coral reefs are under threat from coastal development, fishing, sedimentation and recreational use. Even the most remote reefs are subject to threats such as marine debris, illegal fishing and climate-related effects of coral bleaching, disease and ocean acidification, NOAA said Monday in a release. A 569-page document...

New model will be helpful in designing future marine reservesThe Wildlife Conservation Society (WCS) and the International Institute for Geo-Information Science and Earth have developed a new scientific model that accurately maps where coral reefs are in the most trouble and identifies regions where reefs can be protected best. The model, which is being applied in areas throughout the Indian Ocean, is described in a recent issue of the UK-based journal Ecological Modelling.The model...

Natural processes may prevent oceans from warming beyond a certain point, helping protect some coral reefs from the impacts of climate change, new research finds. The study, by scientists at the National Center for Atmospheric Research (NCAR) and Australian Institute of Marine Science (AIMS), finds evidence that an ocean "thermostat" appears to be helping to regulate sea-surface temperatures in a biologically diverse region of the western Pacific.The research will be published online...

By Jim Loney MIAMI -- Deadly diseases are attacking coral reefs across the Caribbean Sea after a massive surge of coral bleaching last summer, a two-pronged assault that scientists say is one of the worst threats to the region's fragile undersea gardens. The attack, which is killing centuries-old corals, is the result of unusually hot water across the Caribbean region that some scientists argue is a consequence of global warming. Coupled with a recent bleaching event that whitened and...

(RedOrbit) Scientists have been working hard to understand the environmental conditions causing the widespread coral bleaching in Australia's Great Barrier Reef and it's subsequent effects on the global ecology. This work is being aided by NASA satellites which provide scientists with near-real-time sea surface temperature and ocean color data. Australia's Great Barrier Reef is the largest and most complex system of reefs in the world made up of 2,900 reefs spanning over 600 continental...

WASHINGTON (Reuters) - NASA satellites that monitor ocean color and temperature have joined a global effort to study the worrisome bleaching of coral in Australia's Great Barrier Reef, the U.S. space agency said on Wednesday. Coral reefs get bleached when water is too warm, which forces out tiny algae that live in the coral and help it to thrive and give it its vivid color, NASA said in a statement. Without these algae, coral can whiten and eventually die. "Australia's Great Barrier Reef is...

By Michael Perry SYDNEY -- When marine scientist Ray Berkelmans went diving at Australia's Great Barrier Reef earlier this year, what he discovered shocked him -- a graveyard of coral stretching as far as he could see. "It's a white desert out there," Berkelmans told Reuters in early March after returning from a dive to survey bleaching -- signs of a mass death of corals caused by a sudden rise in ocean temperatures -- around the Keppel Islands. Australia has just experienced its warmest year...

SYDNEY, Australia -- A bout of coral bleaching hitting Australia's Great Barrier Reef could be as bad as an episode in 2001-2002 that affected 60 percent of the reef, scientists warned Tuesday. An international team studying the world's reefs said in a statement that water temperatures for the past four months off Australia's northeastern coast have been well above long-term averages. "We were all very concerned when we saw the temperature readings for December," said Prof. Ove Hoegh-Guldberg...

SAN JUAN, Puerto Rico -- Unusually warm waters are bleaching coral reefs throughout the Caribbean, raising fears of a die-off of the important organisms, scientists and environmentalists said Wednesday. Ocean temperatures have been slowly rising, threatening sea coral that can only live within a narrow temperature band, according to the experts. A slight increase in temperature can induce coral bleaching and eventually kill the coral. Recent data gathered by the University of Puerto Rico...
