Any air filled crevice of the human body would collapse in the blink of an eye under this pressure. Lungs filled with air would collapse and the bones would crush. Mariana Trench is the deepest location in earth's crust. Indian Origin scientist Dr Ram Karan draws a picture for how deep it really is.
If you can't breath, your body won't stay alive for more than about 30 minutes. (Although you'd lose consciousness after about 5.) (3) The water pressure is very high. The pressure from the water would push in on the person's body, causing any space that's filled with air to collapse.
On 23 January 1960, two explorers, US navy lieutenant Don Walsh and Swiss engineer Jacques Piccard, became the first people to dive 11km (seven miles) to the bottom of the Mariana Trench. As a new wave of adventurers gear up to repeat the epic journey, Don Walsh tells the BBC about their remarkable deep-sea feat.
The Mariana Trench is deeper than Mount Everest is tall and anything living there has to survive the cold water and extremely high pressure. Some animals, including the deep-sea crustaceans Hirondellea gigas , do live there —and they have recently had a human visitor.
Nothing much. There is an exceedingly high pressure level (according to a quick search ~1000x higher than base pressure at sea level).
While the recommended maximum depth for conventional scuba diving is 130 feet, technical divers may work in the range of 170 feet to 350 feet, sometimes even deeper.
You might expect the waters of the Mariana Trench to be frigid since no sunlight can reach it. And you'd be right. The water there tends to range between 34 to 39 degrees Fahrenheit.
'No. It's definitely not alive in the deep oceans, despite what the Discovery Channel has said in the past,' notes Emma. 'If an animal as big as megalodon still lived in the oceans we would know about it.'
Toward the southern end of the Mariana Trench lies the Challenger Deep. It sits 36,070 feet below sea level, making it the point most distant from the water's surface and the deepest part of the Trench.
Last year an expedition to the Mariana Trench made history by conducting the deepest crewed dive ever completed as it descended 10,927 metres into the Challenger Deep.
The deepest dive
The world's deepest dive on open circuit scuba stands at 332.35m (1,090ft). It was undertaken by Ahmed Gabr in Dahab in the Red Sea on 18/19 September 2014 after nearly a decade of preparation. The descent took only 15 minutes while the ascent lasted 13 hours 35 minutes.
There are near freezing temperatures to contend with, too, with the trench cold enough to again kill most unprotected creatures. Ultimately, though, the pressure is the main difference maker between a voyage to the bottom of the sea and a journey into space.
over 80 trillion years.
Too much pressure would collapse those spaces, crushing us. Animals adapted to deep-ocean life don't have air pockets in their bodies. Some marine animals travel between deep ocean and the surface.
“The intense pressures in the deep ocean make it an extremely difficult environment to explore.” Although you don't notice it, the pressure of the air pushing down on your body at sea level is about 15 pounds per square inch. If you went up into space, above the Earth's atmosphere, the pressure would decrease to zero.
Megalodons succumbed to global cooling due to the shrinking of their habitat, the vanishing of their favorite prey, and competition from other predators 3.5 million years ago.
Although Megalodon teeth are frequently discovered, a full megalodon jaw has never been discovered. Saltwater breaks down cartilage, so all megalodon jaws have likely dissolved.
Fossil remains of megalodon have been found in shallow tropical and temperate seas along the coastlines and continental shelf regions of all continents except Antarctica.
In the Mariana Trench—7,000 meters below the ocean's surface—these fish makes a living in total darkness and at crushing pressures that can reach 1,000 times more than at sea level. But the Mariana snailfish is not only abundant in this area; it's the region's top predator.
Scientists estimate that 91 percent of ocean species have yet to be classified, and that more than eighty percent of our ocean is unmapped, unobserved, and unexplored..
The deepest place in the Atlantic is in the Puerto Rico Trench, a place called Brownson Deep at 8,378m. The expedition also confirmed the second deepest location in the Pacific, behind the Challenger Deep in the Mariana Trench. This runner-up is the Horizon Deep in the Tonga Trench with a depth of 10,816m.
At sea level, pure water boils at 212 °F (100°C). At the lower atmospheric pressure on the top of Mount Everest, pure water boils at about 154 °F (68°C). In the deep oceans, under immense pressure, water remains liquid at temperatures of 750°F (400°C) around hydrothermal vents.
The deepest part of the ocean is called the Challenger Deep and is located beneath the western Pacific Ocean in the southern end of the Mariana Trench, which runs several hundred kilometers southwest of the U.S. territorial island of Guam. Challenger Deep is approximately 10,935 meters (35,876 feet) deep.
