This is the maximum depth at which a submarine is permitted to operate under normal peacetime circumstances, and is tested during sea trials.The test depth is set at two-thirds (0.66) of the design depth for United States Navy submarines, while the Royal Navy sets test depth at 4/7 (0.57) the design depth, and the German Navy sets it at exactly one-half (0.50) of design depth.
Oceanic trenches typically extend 3 to 4 km (1.9 to 2.5 mi) below the level of the surrounding oceanic floor. The greatest ocean depth to be sounded is in the Challenger Deep of the Mariana Trench, at a depth of 10,911 m (35,798 ft) below sea level.
On 7 May 2019, Vescovo and Jamieson, in Limiting Factor, made the first human-occupied deep submersible dive to the bottom of the Sirena Deep, the third deepest point in the ocean, about 128 mi (206 km) northeast of Challenger Deep. They spent 176 minutes at the bottom, and among the samples they retrieved was a piece of mantle rock from the ...

A bathymetric chart is a type of isarithmic map that depicts the submerged bathymetry and physiographic features of ocean and sea bottoms. [1] Their primary purpose is to provide detailed depth contours of ocean topography as well as provide the size, shape and distribution of underwater features.

Deepsea Challenger (DCV 1) was a 7.3-metre (24 ft) deep-diving submersible designed to reach the bottom of the Challenger Deep, the deepest-known point on Earth.On 26 March 2012, Canadian film director James Cameron piloted the craft to accomplish this goal in the second crewed dive reaching the Challenger Deep.
The actual maximum depth is disputed, and estimates range between 3,750 and 4,384 metres (12,303 and 14,383 ft). The average depth of the gulf is roughly 1,615 metres (5,299 ft). [ 3 ] The Sigsbee Abyssal Plain is the deepest and flattest sector of the deep basin.
