Nearly 60 years since he last filmed on the reef, Attenborough has returned to make a three-part series featuring the latest in film techniques and marine science to bring the reef to audiences around the world. Great Barrier Reef with David Attenborough combines cutting edge scientific research alongside innovative filming techniques. By using the very latest infrared cameras, the hatching of the iconic clownfish is witnessed for the very first time whilst time-lapse macro cameras will expose behaviour of the normally unseen tiny coral animals that built the entire Reef and also reveal the most magical reproduction event on the planet, the annual coral spawn. Furthermore, the programme will show how a shrimp with vision like no other animal on the planet views the natural wonder. The Reef is home to some of the world's most fascinating animals and David captures an array of creatures such as the manta ray, the epaulette shark that walks and the humpback whale that have made the Great Barrier Reef their home. The series also uses the latest satellite tracking data to follow the incredible journeys like those of the dwarf minke whales, green turtles and tiger sharks who travel thousands of kilometres to migrate there. However, in the sixty years since David's first visit, the Reef is now seriously under threat. Reflecting on his unique experiences, he explains how the Reef has lost almost half its coral since his first visit and will look at what the future holds for it. He is determined to discover how it can be saved. In his quest he consults the Reef#s top scientists and visits its island research stations where researchers and their teams are trying to help corals cope with the climates rapid change. David's journey also takes him to the deepest part of the Reef where no one has ventured before, in the hi-tech Triton Submersible, to collect corals that may help scientists to better understand this natural wonder of the world.
