Scientists are trying to lighten the clouds to protect the Great Barrier Reef. This was reported by Phys.org with reference to researchers from the University of Southern Cross.
As part of the tests, scientists used a huge fan, similar to a snow cannon, mounted on a boat, to fire salt crystals into the air. Using this procedure, a team led by Professor Daniel Harrison is trying to make the clouds reflect more sunlight into the upper atmosphere, which will lower the water temperature near the reef.
Despite the success of the experiment – the temperature in a small region over which salt was sprayed really decreased, scientists need at least five years to gather evidence for new experiments. In addition, the impact of these experiments on the environment and the Great Barrier Reef is not fully known.
In the following experiments, scientists will conduct experiments 10 times larger, including through the use of small turbines on special barges. Such procedures will reduce coral mortality by 70%, Harrison believes.
Coral bleaching occurs when they experience severe stress as a result of changes in ocean temperature and begin to expel algae from themselves. This leads to a decrease in their brightness and death. The Great Coral Reef has begun to decolorize en masse over the past five years, and scientists believe that this may be a process that can no longer be changed.
