The Great Barrier Reef, it's big, it's colourful, it's one of our world's great natural wonders and it's full of science. So what better subject to dedicate a whole show to than the reef? Join Dr Rob as he scopes out what it is that makes up a reef ecosystem and investigates some of the imminent threats that coral reefs face, such as bleaching and climate change.REEF SCIENCE 101The main thing most people associate with a tropical reef is coral. But what the blazes is coral? Are all corals the same? And what role does zooxanthellae play? Dr Rob travels to tropical Green Island on the Great Barrier Reef to find out.REEF ECOLOGYDespite taking up less than 1% of the ocean floor, coral reefs provide homes, food and protection for about 25% of the world's marine species. This makes reefs one of the most diverse habitats in the world. Hayley Gorsuch from the Reef and Rainforest Research Centre introduces us to the many creatures that call the reef home. AQUARIUM SCIENCEYou don't have to be at the reef to see all the amazing animals that live there thanks to huge aquariums. But how on earth do they replicate this wonderful underwater world? Julia visits Underwater World and chats to Danielle Miles to find out.CLIMATE CHANGE AND THE REEFThe impacts of Climate Change are starting to be felt around the world and the Great Barrier Reef hasn't escaped. Dr. David Wachenfeld, Chief Scientist for the Great Barrier Reef Marine Park Authority explains how climate change is threatening the reef and what we can do to help.CORAL BLEACHINGThere are a number of threats to reef and none bigger than the phenomenon know as Coral Bleaching. But what exactly is coral bleaching and why does it happen? Lead expert Professor Ove Hoegh-Guldberg from the University of Queensland answers all these tricky questions. WATER QUALITYThe Great Barrier Reef is a finely balanced ecosystem which depends on certain conditions remaining constant, in particular the quality of the water that flows into the ocean. Tony Webster from CSIRO Sustainable Ecosystems explains how he's working with farmers to only put back what was naturally there.So join Dr Rob to discover all science behind the reef, as he once again proves that the ordinary really does become extraordinary under the SCOPE! |
