Marine biologist Sylvia Earle has spent more than four decades at the forefront of ocean exploration.And, at 83, she shows no signs of slowing down.Earle was the first female chief scientist of the U.S. National Oceanic and Atmospheric Administration,and was named Hero of the Planet in 1998 by TIME magazine.In tonight's Brief But Spectacular, she reflects on her passion for the ocean and the planet.The ocean got my attention when I was about 3 years old. A wave sneaked up behind me and knocked me off my feet.My mother, kind of the mother of all mothers, instead of racing out to take me out of the ocean forever,saw the big smile on my face and let me run back in.And I have been running back in ever since.Two words of instruction, breathe naturally, and over the side, I went.It took a few seconds, no more, before I felt like I belonged there. Four decades ago, I had a chance to do some research.There is a new tool in the sea. It can withstand pressure up to 2,000 feet.Dr. Sylvia Earle is a marine biologist. Her question, can scientists use the JIM suit for dives over 1,000 feet?
