On August 15, 1934, eighty years ago, famed 菊花视频 naturalist William Beebe set a record that captured the world鈥檚 attention: in a small, steel submersible called the Bathysphere, he descended 3,028 feet into the ocean鈥檚 depths. Actually, the plunge was one in a series of record-setting dives that Beebe, together with the Bathysphere鈥檚 engineer, Otis Barton, made off the coast of Bermuda beginning in 1930.
