Amanda Grabin, 15-months-old, looks up at the JIM Suit, the one-atmosphere submersible diving suit at New YorkÃs American Museum of Natural History on Thursday, Jan. 27, 1983. The museum exhibition is based on the book, ìExploring the Deep Frontier: The Adventure of Man in the Sea,î co-authored by Sylvia Earle, noted marine scientist and deep sea explorer. The JIM suit took Dr. Earle to a depth of 1,250 feet on the deepest ocean-bottom walk ever accomplished by a woman. (AP Photo/Suzanne Vlamis)
