Dr. Carl Safina, on-camera host for the series, is a marine biologist by training, best-selling author of popular books about ocean subjects, and founder of the conservation organization, Blue Ocean Institute.

Safina has studied the ocean as a scientist, stood for it as an advocate, and conveyed his global travels among sea creatures and fishing people in lyrical non-fiction writing. His hundred-plus publications and award-winning books include Song for the Blue Ocean, Eye of the Albatross and Voyage of the Turtle. His latest book, The View from Lazy Point: A Natural Year in an Unnatural World, has received wide critical acclaim. He's been profiled by The New York Times, Nightline, and Bill Moyers. His awards include a Pew Fellowship, Lannan Literary Award, John Burroughs Medal, and a MacArthur Prize, among others (not forgetting the Popular Science "Worst Jobs in Science" Award, second place).
