Coral bleaching is a phenomenon that occurs when coral becomes stressed due to changing conditions and expels the algae that live inside their tissue, causing the coral to become white.

Researchers working on the so-called Cloud Brightening project said they use a turbine to spray microscopic sea particles to thicken existing clouds and reduce sunlight.

As a result of the order, 173 baited drum lines at 27 beaches between Cairns in the north and Gladstone in the south, will be taken out of the water.
High turbidity, higher ocean temperatures and changing ocean chemistry affect recovery rates and more frequent disturbances shorten periods of recovery time of reefs.
According to researchers, the number of coral larvae that are produced each year, and where they travel to before settling on a reef, are vital components of the resilience of the Great Barrier Reef.
