<P> The Challenger Deep is the deepest known point in the Earth 's seabed hydrosphere , with a depth of 10,898 to 10,916 m ( 35,755 to 35,814 ft ) by direct measurement from submersibles , and slightly more by sonar bathymetry . It is in the Pacific Ocean , at the southern end of the Mariana Trench near the Mariana Islands group . The Challenger Deep is a relatively small slot - shaped depression in the bottom of a considerably larger crescent - shaped oceanic trench , which itself is an unusually deep feature in the ocean floor . Its bottom is about 11 km ( 7 mi ) long and 1.6 km ( 1 mi ) wide , with gently sloping sides . The closest land to the Challenger Deep is Fais Island ( one of the outer islands of Yap ) , 287 km ( 178 mi ) southwest , and Guam , 304 km ( 189 mi ) to the northeast . It is located in the ocean territory of the Federated States of Micronesia , 1.6 km ( 1 mi ) from its border with ocean territory associated with Guam . </P>
