Sylvia Earle has been at the frontier of deep ocean exploration for four decades. She's led more than 50 undersea expeditions, and she's been an equally tireless advocate for our oceans and the creatures who live in them.

Why you should listen

Sylvia Earle, called "Her Deepness" by the New Yorker and the New York Times, "Living Legend" by the Library of Congress and "Hero for the Planet" by Time, is an oceanographer, explorer, author and lecturer with a deep commitment to research through personal exploration.

Earle's work has been at the frontier of deep ocean exploration for four decades. Earle has led more than 50 expeditions worldwide involving more than 6,000 hours underwater. As captain of the first all-female team to live underwater, she and her fellow scientists received a ticker-tape parade and White House reception upon their return to the surface. In 1979, Sylvia Earle walked untethered on the sea floor at a lower depth than any other woman before or since. In the 1980s she started the companies Deep Ocean Engineering and Deep Ocean Technologies with engineer Graham Hawkes to design and build undersea vehicles that allow scientists to work at previously inaccessible depths. In the early 1990s, Dr. Earle served as Chief Scientist of the National Oceanographic and Atmospheric Administration. At present she is explorer-in-residence at the National Geographic Society.

Sylvia Earle is a dedicated advocate for the world's oceans and the creatures that live in them. Her voice speaks with wonder and amazement at the glory of the oceans and with urgency to awaken the public from its ignorance about the role the oceans plays in all of our lives and the importance of maintaining their health.

“We've got to somehow stabilize our connection to nature so that in 50 years from now, 500 years, 5,000 years from now there will still be a wild system and respect for what it takes to sustain us.” — Sylvia Earle

Stevens co-directed the newly-released doc Mission Blue, spending the last four years trekking around the world—from the Galapagos Islands to the Chesapeake Bay to the Great Barrier Reef—with unstoppable oceanographer Sylvia […]

Quotes from Sylvia Earle

I’m haunted by the thought of what Ray Anderson calls ‘tomorrow’s child,’ asking why we didn’t do something on our watch to save sharks and bluefin tuna and squids and coral reefs and the living ocean while there still was time. Well, now is that time.

I hope that someday we will find evidence that there is intelligent life among humans on this planet.
