Reef Q&A: What is coral bleaching? Your Great Barrier Reef questions answered ft. Roger Beeden

Coral bleaching, tropical cyclones and flooding are placing increasing pressure on the Great Barrier Reef. But what do these impacts actually mean for the Reef, and how is it responding?

In this episode of Reef in Focus, host Lincoln Bertoli is joined by Reef Authority Chief Scientist Dr Roger Beeden aboard the Reef Sentinel to answer common questions about coral bleaching, severe weather and Reef resilience. Together, they explore what causes coral bleaching, why it doesn't always mean coral death, and how corals can recover when conditions improve.

They also discuss how tropical cyclones, flooding and marine heatwaves can combine to affect the Reef, why some reefs are more resilient than others, and how long-term monitoring helps scientists understand recovery and guide management decisions.

Dr Beeden explains the role of resilience-based management, crown-of-thorns starfish control, water quality improvements and marine park zoning in supporting the Reef's recovery in a changing climate.

Whether you're interested in marine science, conservation or the future of the Great Barrier Reef, this episode provides an accessible explanation of the challenges facing coral reefs and the actions being taken to help protect this World Heritage Area for future generations.
