Challenger Deep

Deepest known point of Earth's seabed

The Challenger Deep is the deepest known point of the seabed of Earth, located in the western Pacific Ocean at the southern end of the Mariana Trench, in the ocean territory of the Federated States of Micronesia. The GEBCO Gazetteer of Undersea Feature Names indicates that the feature is situated at 11°22.4′N 142°35.5′E and has an approximated maximum depth of 5,962 to 6,020 fathoms (10,903 to 11,009 m; 35,772 to 36,120 ft) below sea level. A 2011 study placed the depth at 5,971 ± 5 fathoms (10,920 ± 9 m; 35,826 ± 30 ft) with a 2021 study revising the value to 10,935 ± 6 m (35,876 ± 20 ft) at a 95% confidence level.
