mrmoshe Posted November 2, 2006 Posted November 2, 2006 Great Barrier Reef may be 'hosed down' SCIENTISTS are considering a plan to make the water of the Great Barrier Reef cooler for corals vulnerable to the damage from climate change. Great Barrier Reef Marine Park Authority (GBRMPA) executive director Andrew Skeat today said the proposal would involve watering the surface of the ocean at peak times of heat stress to avoid coral bleaching. "It's a proposal ... which would simply pump a fine spray of seawater onto the surface which would just break up the water surface and reduces the amount of (UV) radiation," Mr Skeat said. "It's not an ecological scale solution to climate change, but it could be one response to keeping particular areas with high coral cover." Little detail was available today of how spraying would be implemented, but it would most likely involve relatively small, localised areas of particular high tourism value, with vulnerable coral. Coral bleaching is caused by higher than average water temperatures linked with global climate change. Mr Skeat, who participated in the Ecotourism Australia Conference in Townsville this week, said climate change would eventually affect the way tourism operated on the Great Barrier Reef. He said a marine tourism working group, established to prepare for climate change on the reef, was considering other options such as permanently placing shade cloth over some areas. Mr Skeat said studies had found the measure, first trialled in 2004, was effective in reducing radiation and coral bleaching. "Whether it becomes practicable and cost effective is another question," he said. Mr Skeat said the group also was looking at whether site-based operations could become "more flexible" and move to different parts of the reef during a significant coral bleaching event. "There might have to be adjustments in people's operations if, for example, areas of the reef are damaged ... Those areas might have to be given a rest," he said. "I have to say that the industry is positive about that, they're not fighting that." Mr Skeat said while marine ecosystems around the world were at risk from climate change, Australia had "the best shot" of preserving its own because of stringent federal government management.
Yoda Posted November 2, 2006 Posted November 2, 2006 What a load of rubbish, sounds like a marine scientist trying to keep his funding going for a few more years, and guess what, the government might just believe him and give him 1/2 a million of our $ to see if his idea works.
