Sylvia Earle

Dr. Sylvia Earle

Named Time magazine’s first “hero for the planet” in 1998, marine biologist Sylvia Earle has pioneered research on marine ecosystems. She has led more than 50 expeditions—that’s more than 6,000 hours underwater. Earle has been an explorer-in-residence at the National Geographic Society since 1998. She holds many diving records, including the women’s depth record for solo diving at a thousand meters (3,300 feet).
