How deep is the ocean? At 36,070 feet (10,994 meters) below sea level, Challenger Deep in the Pacific Ocean’s Mariana Trench is the ocean’s deepest known point.
The exact depth of the Challenge Deep was discovered in 2021 thanks to remote-operated submersible vehicles. On average, the ocean is around 3.7km deep (3,688m to be exact), according to the US National Oceanic and Atmospheric Administration (NOAA).
The deep sea is broadly defined as the ocean depth where light begins to fade, at an approximate depth of 200 m (660 ft) or the point of transition from continental shelves to continental slopes. [1] [2] Conditions within the deep sea are a combination of low temperatures, darkness, and high pressure. [3]
The very deepest depth of the ocean is roughly 2,000 meters deeper than Mount Everest is tall—36,070 feet deep (10,994 m)! Each zone has a different mix of species adapted to its specific light level, pressure, temperature, and community.
