Ultramarine: the science of our oceans and waterways episodes

  • How you can help save the Great Barrier Reef

    In this Ultramarine episode of the Connect Sci Podcast, host David Boldeman speaks with Sean Daly from Citizens of the Reef about how students, teachers, and everyday Australians can play a real role in protecting the Great Barrier Reef.


    Sean explains the major threats facing coral reefs — especially climate change and outbreaks of Crown-of-Thorns Starfish — and why traditional scientific monitoring can only cover a small fraction of this vast marine system. He talks about the Great Reef Census, a global citizen-science project where divers, tourists, schools, and volunteers photograph and analyse reef images to build the most comprehensive picture yet of reef health.
