Let’s deep dive into our new episode of Ask An Expert as we explore the Great Barrier Reef – as voted by you! We're joined by marine biologist Dr Emma Camp from @utschannel, Team Leader of the Future Reefs Program and Coral Nurture Program Co-Founder. *QUESTIONS:* 1. How big is the GBR? 2. What exactly is coral? 3. How do corals know to spawn in unison, even when far apart? 4. What is the current state of the Great Barrier Reef? 5. What causes coral to bleach? 6. What are scientists doing to boost the health of the GBR? 7. Are corals being bred to form a population to potentially recolonise the reef at a later date if necessary? 8. Are efforts to save the GBR, such as growing coral on frames, shade cloths, breeding corals to recolonise the reef, and geoengineering the sky to reflect sunlight all futile due to governments globally not doing enough to beat climate change? 9. Is it possible to re grow a dead coral reef? 10. What are the most endangered animals in the Great Barrier Reef? 11. How many turtle species live in the Great Barrier Reef? 12. What is happening with the crown of thorns starfish? Are the numbers being reduced? How? 13. Has anyone tried repopulation of Triton shells which apparently eat crown of thorns starfish? Is this feasible? 14. How are the fertiliser run-off problems from the rivers and estuaries in northern Queensland being managed? 15. Is the reef moving southward as the climate warms or if it is, and it's not climate, is this just current longshore drift of coral spawn? 16. Are there any major biological differences between the GBR and Ningaloo Reef? 17. Is 'Finding Nemo' an accurate depiction of the Great Barrier Reef? 18. What unique animals call the Great Barrier Reef home? How much of the wildlife is only found in the GBR?
