Artificial fog and breeding coral: study picks best Great Barrier Reef rescue ideas

Australian government to back 43 concepts in ambitious $150m research and development program

Brightening clouds with salt crystals and deploying slicks of coral larvae to try and limit the impacts of global heating on the Great Barrier Reef are among more than 40 concepts being backed by the Australian government in an ambitious $150m research and development program.

A two-year feasibility study released by the government on Thursday has reduced about 160 potential ideas to a list of 43 that will be funded for further investigation under the Reef Restoration and Adaptation Program (RRAP).
