Effects of an underwater explosion depend on several things, including distance from the explosion, the energy of the explosion, the depth of the explosion, and the depth of the water. [2] Underwater explosions are categorized by the depth of the explosion. Shallow underwater explosions are those where a crater formed at the water's surface is ...
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%.
Water depth measurable by lidar depends on the clarity of the water and the absorption of the wavelength used. Water is most transparent to green and blue light, so these will penetrate deepest in clean water. [10] Blue-green light of 532 nm produced by frequency doubled solid-state IR laser output is the standard for airborne bathymetry.
"For example, 33 feet of water depth overhead is equal to the entire weight of the atmosphere above each of us every day. At 12,500 feet, that pressure is almost 400 times greater across the ...
The platform commenced drilling in February 2010 at a water depth of approximately 5,000 feet (1,500 m). [12] At the time of the explosion the rig was drilling an exploratory well. [13] The planned well was to be drilled to 18,360 feet (5,600 m) below sea level, and was to be plugged and suspended for subsequent completion as a subsea producer ...
Underwater explosions using dry ice and liquid nitrogen are captured in high definition slow motion by The Backyard Scientist.
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 .
The underwater explosion also sent 146 million tons of water from the South Pacific Ocean into the stratosphere. [60] The amount of water vapor ejected was 10 percent of the stratosphere's typical stock. [61] It was enough to temporarily warm the surface of Earth. It is estimated that an excess of water vapour should remain for 5–10 years. [59]
