40 years, thousands of surveys and one extraordinary dataset. In this special episode of Reef in Focus, Lincoln Bertoli is joined by Mike Emslie from the Australian Institute of Marine Science and the Reef Authority's Chief Scientist, Roger Beeden, to celebrate 40 years of the Long-Term Monitoring Program. Together, they explore how one of the world's most comprehensive coral reef monitoring programs has transformed our understanding of the Great Barrier Reef, from tracking Crown-of-Thorns Starfish outbreaks to measuring coral recovery and resilience. They also reveal how decades of consistent scientific data help the Reef Authority make smarter, evidence-based management decisions that protect the Reef today and into the future.
