Deepest point in Earth’s oceans

Last updated: May 18, 2018 at 17:55 pm

10,994 m (36,070 ft) — The Challenger Deep, located in the Mariana Trench, 250 miles (400 km) southwest of Guam in the Pacific Ocean, is the deepest known point on the planet. It is named after the British survey ship Challenger II, which first surveyed the trench in 1951. The first humans to descend to Challenger Deep were Dr. Jacques Piccard and Dr. Don Walsh aboard the bathyscaphe Trieste (10,916 m / 35,814 ft) in 1960. James Cameron made the first solo descent to the Challenger Deep in 2012.

Depth surveyed by the United States Center for Coastal & Ocean Mapping in 2010 (± 40 m / 130 ft)
