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 seabed (also known as the seafloor, sea floor, ocean floor, and ocean bottom) is the bottom of the ocean. All floors of the ocean are known as 'seabeds'. The structure of the seabed of the global ocean is governed by plate tectonics. Most of the ocean is very deep, where the seabed is known as the abyssal plain. Seafloor spreading creates ...
Sonar mapping of the Challenger Deep by the DSSV Pressure Drop employing a Kongsberg SIMRAD EM124 multibeam echosounder system (26 April–4 May 2019). Challenger Deep (CD) is the deepest known point in the Earth's seabed hydrosphere, a slot-shaped valley in the floor of Mariana Trench, with depths exceeding 10,900 meters. [1]
A daring deep sea search has found tiny pieces of a mysterious meteor that crashed to Earth in 2014. The ‘alien hunter of Harvard’ tells Bevan Hurley the discovery may be evidence of an ...
The floor of the ocean off the coast of the Pacific Northwest has sprung a leak called Pythia's Oasis. Here's what that means. Oh Dear, There's a Hole in the Bottom of the Ocean
Sonar mapping of the Challenger Deep by the DSSV Pressure Drop employing a Kongsberg SIMRAD EM124 multibeam echosounder system (26 April – 4 May 2019). The Challenger Deep is a relatively small slot-shaped depression in the bottom of a considerably larger crescent-shaped oceanic trench, which itself is an unusually deep feature in the ocean floor.
Globally, there are over 50 major ocean trenches covering an area of 1.9 million km 2 or about 0.5% of the oceans. [4] Trenches are geomorphologically distinct from troughs. Troughs are elongated depressions of the sea floor with steep sides and flat bottoms, while trenches are characterized by a V-shaped profile. [4]
Lying at the bottom of the Pacific Ocean is a massive graveyard containing more than 150 WWII planes. Brandi Mueller, a coast guard officer from Wisconsin, was scuba diving in the Marshall Islands ...
