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 ...
"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 ...
Depth Range: Shallow water; Weight: 754 kg (1,662 lb) Explosives: 230 kg (510 lb) high explosive; Date Deployed: 1987; MK 62 Quick Strike deployed from a P-3 Orion. MK65 Quickstrike The Quickstrike [102] is a family of shallow-water aircraft-laid mines used by the United States, primarily against surface craft. The MK65 is a 910 kg (2,000 lb ...
Underwater explosions using dry ice and liquid nitrogen are captured in high definition slow motion by The Backyard Scientist.
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.
Below ocean depths of about 2,200 metres (7,200 ft) where the pressure exceeds the critical pressure of water (22.06 MPa or about 218 atmospheres for pure water), it can no longer boil; it becomes a supercritical fluid. Without boiling sounds, deep-sea volcanoes can be difficult to detect at great distances using hydrophones. [citation needed]
Tsunamis generated by underwater volcanic explosions depend on the energy and water depth of the explosion. An underwater explosion resulting in the formation of a crater can cause subsequent expansion, rise and gravitational collapse to create tidal bores, as well as smaller waves. [3]
