Ocean depth recordIn 1960, a specially constructed bathyscaphe, the Trieste, descended 35,810 feet in the Pacific Ocean into Challenger Deep. This, the deepest point known to exist on earth, is in the Marianas Trench near the island of Guam. The Trieste cabin was a six-foot diameter steel capsule weighing 14 tons engineered by Swiss scientist Auguste Piccard to withstand the 16,000 lbs/sq.in. water pressure at that depth. Jacques Piccard (Auguste's son) and Navy Lieutenant Don Walsh made the five-hour descent, setting a deep-diving record. Through their window, they saw a foot-long fish, and thus answered the question of biologists who long wondered whether life could exist at such depths of the ocean. The record has stood unchallenged for 40 years since their historic dive. |
