There are about 50,000 km (31,000 mi) of oceanic trenches worldwide, mostly around the Pacific Ocean, but also in the eastern Indian Ocean and a few other locations. The greatest ocean depth measured is in the Challenger Deep of the Mariana Trench, at a depth of 10,994 m (36,070 ft) below sea level .
Dec 5, 2018 · These regions are called the deep ocean trenches and if they were on a continent, they'd be deep jagged canyons. These dark, once-mysterious canyons plunge down as far as 11,000 meters (36,000 feet) into our planet's crust.
deep-sea trench, or oceanic trench, Any long, narrow, steep-sided depression in the ocean bottom in which maximum oceanic depths (24,000–36,000 ft, or 7,000–11,000 m) occur. The deepest known depression of this kind is the Mariana Trench.

Mar 31, 2023 · Oceanic trenches are found in the deepest ocean areas at maximum oceanic depths ranging between 24,000 to 36,000 ft, mainly at subduction zones on convergent plate boundaries. There are estimated to be more than 50 significant ocean trenches worldwide, occupying an area of 1.9 million sq. km, i.e., only 0.5% of the world’s oceans.
