Called a living legend by the Library of Congress, Sylvia Earle is an oceanographer, explorer, author and lecturer. She has led more than 60 expeditions and logged more than 6,000 hours underwater. A former chief scientist at NOAA, Earle is founder of the Mission Blue Foundation and a National Geographic Explorer-in-Residence. Part actionadventure, part exposé of an eco-disaster, Mission Blue focuses on her mission to save the globe’s oceans. More than 100 scientists, philanthropists and activists gather in the Galapagos Islands to help fulfill Dr. Earle’s lifelong wish: build a global network of marine protected areas, like underwater national parks, to protect the natural systems that keep humans alive. As the expedition ends, the Deep Water Horizon oil well explodes. With oil gushing into the Gulf of Mexico, Earle and an environmental dream team race around the world trying to defend her ‘Hope Spots’. Directed and produced by Bob Nixon and Fisher Stevens.
