DR SYLVIA EARLE IS A WOMAN OF MANY FIRSTS: She was the first female chief scientist of the U.S. National Oceanic and Atmospheric Administration, LA Time’s Woman of the Year in 1970, ordained a knight in 1981, named by Time Magazine as its first Hero for the Planet in 1998. In 1979, she made an open-ocean JIM suit dive to the sea floor alone near Oahu, setting a women's depth record of 381 metres. In 2009, she won a TED Prize, and with TED's support, she launched Mission Blue, which aims to establish marine protected areas (“Hope Spots") around the globe. In 2014, she was named Glamour Woman of the Year, a UN Champions of the Earth Award, and the first woman to be celebrated at an Explorers Club Tribute Ceremony. We are honoured to have Dr Sylvia Earle as Chair of the Ocean Geographic’s Honorary Editors Board. Here, she shares with us some of her deep secrets.
