The trench is between 1 and 2 nautical miles (1.9 and 3.7 km; 1.2 and 2.3 mi) wide and hundreds of metres deep. [4] Off the Rogaland coast, it is 250–300 m (820–980 ft) deep, and at its deepest point, off Arendal, it reaches 700 m (2,300 ft) deep as compared to the average depth of the North Sea, about 100 m (330 ft).

The deepest point of the trench is more than 2 km (1.2 mi) farther from sea level than the peak of Mount Everest. [a] At the bottom of the trench, the water column above exerts a pressure of 1,086 bar (15,750 psi), more than 1,071 times the standard atmospheric pressure at sea level. At this pressure, the density of water is increased by 4.96%.
The North Sea located on the continental shelf has different waves from those in deep ocean water. The wave speeds are diminished and the wave amplitudes are increased. In the North Sea there are two amphidromic systems and a third incomplete amphidromic system.
This is the Mariana Trench - the deepest point on Earth - found in the Western Pacific Ocean.GARRIOTT: “It is almost 11,000 meters of sea water deep, that is deeper than Mount Everest is high ...
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. Oceanic trenches are a feature of the Earth's distinctive plate tectonics .
Milwaukee Deep, also known as the Milwaukee Depth, is the deepest part of the Puerto Rico Trench, constituting the deepest points in the Atlantic Ocean. [1] Together with the surrounding seabed area, known as Brownson Deep, the Milwaukee Deep forms an elongated depression that constitutes the floor of the trench. As there is no geomorphological ...
The purple sea floor at the center of the view is the Puerto Rico Trench, the deepest part of the Atlantic Ocean. The Puerto Rico Trench is located on the boundary between the North Atlantic Ocean and Caribbean Sea, parallel to and north of Puerto Rico, where the oceanic trench reaches the deepest points in the Atlantic Ocean.
Kelly Walsh dived 11,000m under the ocean to Challenger Deep, 60 years after his father Don Walsh made the journey. He tells Bevan Hurley he’s watched the Titan rescue in ‘horror and sadness’
