Bathyscaphe Trieste
On 23 January 1960, she reached the ocean floor in the Challenger Deep (the deepest southern part of the Mariana Trench), carrying Jacques Piccard and Don Walsh. This was the first time a vessel, manned or unmanned, had reached the deepest known point of the Earth's oceans. The onboard systems indicated a depth of , although this was revised later to ; fairly recently, more accurate measurements have found Challenger Deep to be between and deep.
Gloria Hollister
Also in Bermuda, Hollister set the world record for the deepest dive undertaken by a woman. She performed the dive in the Bathysphere, a large steel submersible in which Beebe and the Bathysphere’s engineer, Otis Barton, undertook deep sea explorations throughout the early 1930s. On June 11, 1930, her thirtieth birthday, she went down 410 feet for the women’s descent record. In 1934, she would nearly triple her own record by descending to 1,208 feet. The dives were not simply feats for Hollister but, as for Beebe, a chance to explore the deep-sea world.
