Australia announced plans last Friday to explore concepts such as shooting salt in the clouds and covering vast expanses of water with a thin layer of film for the purpose of save the Great Barrier Reef. the size of Japan or Italy, undergoes two consecutive years of bleaching because of rising sea temperatures due to climate change.
Experts warned that 2,300 kilometers long would have suffered irreparable damage. he's committed to tackling climate change – the biggest threat to the world's largest life structure – he's also been pushed to explore shorter-term measures to buy the reef.
Canberra offered $ 2 million to attract innovative ideas to protect the site, which is also under pressure from runoff, development and predatory starfish from starfish.
& # 39; Sun shield & # 39;
total One of the concepts retained is that of lightening clouds where salt crystals harvested from seawater are projected into the clouds, making them makes it more reflective and therefore diverts the sun's rays into space.
David Mead, a researcher at the Australian Institute of Ocean Sciences, said the idea might seem far-fetched, but the proposal has real potential.
"The team sought to use a very fine nozzle to pump small droplets of salt water." The water vaporizes and you still have a particle of salt that will float around, and if you can introduce these into the system, you can increase the amount of sunlight. reflected back. "
Another idea was a biodegradable" solar shield ", where an ultra-thin film containing light-reflecting particles covers some reef waters to protect the corals against heat stress.
" The great thing about The film is a thick molecule, so you can swim straight ahead and it will continue to self – do, "said Andrew Negri of the Australian Institute of Ocean Sciences at the University of California. ABC.
Other short-listed projects include the production of coral larvae using 3D printed surfaces to support new growth, and large-scale harvesting and relocation of larvae
Commissions Experimental arrived Friday in Canberra. first unveiled in 2015 – to protect the reef, with other measures to improve the quality of water.
