Sylvia EarleMarine biologist Sylvia Earle--sometimes known as "Her Deepness" or "The Sturgeon General"--has been an Explorer-in-Residence at the National Geographic Society since 1998. Named Time magazine's first "hero for the planet" in 1998, Earle has pioneere research on marine ecosystems and has led more than 50 expeditions totaling more than 6,000 hours underwater. She holds numerous diving records, including setting the women's depth record for solo diving at a thousand meters (3,300 feet).

Former Chief Scientist for the U.S. National Oceanic and Atmospheric Administration (NOAA), Earle is author of more than 125 scientific and popular publications, including Sea Change. Her research places special emphasis on marine plants and the development of technology for access and research in the deep sea. She played a key role in a decision in early 1999 by the Clinton Administration to double the budget of the U.S. National Marine Sanctuaries.

Earle works with the Society on projects involving her passion--most recently as project director of the Sustainable Seas Expeditions. Sustainable Seas was a five-year project of the National Geographic Society and NOAA, which administers the 12 U.S. marine sanctuaries, the underwater equivalents of national parks. The objective of the initiative was to explore and photodocument the geology and creatures in the deep waters of each of the sanctuaries. Earle also has written three books for the Society, two children's titles and Wild Ocean: America's Parks Under the Sea.

Earle was born August 30, 1935, in Gibbstown, New Jersey. She has a bachelor's degree from Florida State University and a master's degree and doctorate from Duke University as well as 12 honorary doctorate degrees. She lives in Oakland, California.
