Because pressure in the ocean increases by about 1 atmosphere for every 10 meters of depth, the amount of pressure experienced by many marine organisms is extreme. Until recent years, the scientific community lacked detailed information about the effects of pressure on most deep sea organisms because the specimens encountered arrived at the ...
Critical pressure of water 28 MPa 4,100 psi Overpressure caused by the bomb explosion during the Oklahoma City bombing [72] 40 MPa 5,800 psi Water pressure at the depth of the wreck of the Titanic: 69 MPa 10,000 psi Water pressure withstood by the DSV Shinkai 6500 in visiting ocean depths of > 6500 meters [73] 70 to 280 MPa 10,000 to 40,000 psi
Temperatures in the Mesopelagic zone range from 5 to 4 °C (41 to 39 °F). The pressure is higher here, it can be up to 10,100 kilopascals (1,460 psi) and increases with depth. [1] 54% of the ocean lies in the Bathypelagic (aphotic) zone into which no light penetrates. This is also called the midnight zone and the deep ocean.
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%. [citation needed] The temperature at the bottom is 1 to 4 °C (34 to 39 °F). [4]
At Titanic depths, some 12,500 feet down, the water pressure is nearly 400 times more than at the ocean's surface — some 6,000 pounds would have been pressing down on every square inch of Titan ...
The hydrostatic pressure in this zone ranges from 100-400 atmospheres (atm) due to the increase of 1 atm for every 10 m depth. [3] It is believed that these conditions have been consistent for the past 8000 years. [2] This ocean depth spans from the edge of the continental shelf down to the top of the abyssal zone, and along continental slope ...
Organisms in the abyssal zone rely on the natural processes of higher ocean layers. When animals from higher ocean levels die, their carcasses occasionally drift down to the abyssal zone, where organisms in the deep can feed on them. When a whale carcass falls down to the abyssal zone, this is called a whale fall. The carcass of the whale can ...
The hadopelagic (or hadal) zone, refers to depths below 6000 meters, which occur mostly in the deep ocean trenches. The term hadal is a reference to the Greek god of the underworld Hades. In these trenches, the temperature is just above freezing, and the water pressure is enormous.
