Last year, the Catlin Seaview Survey completed the most detailed picture of Australia's Great Barrier Reef. Using underwater vehicles with 360-degree cameras, the survey's scientists and divers captured more than 100,000 panoramic photographs. Panoramas save precious time—experts think the reef could disappear entirely in the next couple of decades. The team hopes the comprehensive look at the ecosystem will provide insights about how to save it and others around the world. Next, the crew, led by scientist Ove Hoegh-Guldberg of the University of Queensland, will shoot reefs in the Philippines.
