Diving the Coral Reef at Twilight with Richard Pyle

Richard Pyle Dives the Twilight Zone as part of TED.com's Ocean Series talks:

A pioneer of the dive world, Richard Pyle discovers new biodiversity on the cliffs of coral reefs. He was among the first to use rebreather technology to explore depths between 200 and 500 feet, an area often called the "Twilight Zone." During his dives, he has identified and documented hundreds of new species. Author of scientific, technical and popular articles, his expeditions have also been featured in the IMAX film Coral Reef Adventure, the BBC series Pacific Abyss and many more. In 2005, he received the NOGI Award, the most prestigious distinction of the diving world.
Currently, he is continuing his research at the Bernice P. Bishop Museum, outside Honolulu, Hawai'i, and is affiliated with the museum's comprehensive Hawaii Biological Survey. He also serves on the Board of Directors for the Association for Marine Exploration, for which he is a founding member. - TED.com
