第 1 季，第 1 集: Almost 60 years after his first visit to the Great Barrier Reef, Sir David Attenborough returns to unlock new secrets about the largest living structure on Earth. Working with a team of experts aboard a state-of-the-art research and exploration vessel, David takes us to mysterious depths for an up-close look at the wonderfully diverse community that calls this place home. Through computer modeling and radiocarbon dating, we uncover surprising details about the reef’s origins, which are more recent than once believed.
