Great Barrier Reef
Begins 14 Jan, Mon, Wed & Fri, 9pm
This first episode looks at the extraordinary structure of Australia’s Great Barrier Reef, and how it is constantly changing, responding to rhythms of weather, tides, the sun and the moon. Cutting-edge underwater macro and digital time-lapse photography provide new perspectives on this natural wonder.
The Great Barrier Reef covers an area larger than Britain, but only 7% of it is coral reef. The rest is a variety of habitats including the world’s oldest jungle, islands, mangrove swamps, sand flats and meadows of sea grass, all connected by a giant deep-water lagoon. The marine life found in this lagoon is truly spectacular.
From turtles that migrate thousands of miles across the Pacific Ocean, to whales travelling here each year from the Antarctic, creatures cover vast distances to visit the Great Barrier Reef. The final episode reveals how the reef is crucially connected to the rest of the planet – and how climate change will affect its future.
