Called "Her Deepness" by The New Yorker and the New York Times, a "Living Legend" by the Library of Congress, and a "First Hero for the Planet" by Time magazine, she is an oceanographer, explorer, author, and field scientist. In 1970, told she could not join a crew of men testing an undersea habitat, she organized an all-female crew, and they lived underwater for weeks, pioneering deep-sea ventures. Since then, she has continued to cross boundaries, always passionately advocating on behalf of Earth's ocean.
