A: It’s a form of decompression sickness initially observed in deep sea divers. At great depths under water the excess pressure causes nitrogen gas to be absorbed into the blood. If the diver surfaces too quickly the nitrogen forms bubbles in the blood which raise havoc in the body.
Is it possible to swim to the bottom of the ocean?
But reaching the lowest part of the ocean? Only three people have ever done that, and one was a U.S. Navy submariner. In the Pacific Ocean, somewhere between Guam and the Philippines, lies the Marianas Trench, also known as the Mariana Trench. … Challenger Deep is the deepest point of the Marianas Trench.
How long would it take to swim up from the bottom of the ocean?
First off, nobody could free swim to the “bottom of the ocean.” Two reasons come to mind. First, it takes about four hours to descend in a deep sea submersible to the bottom of the Challenger Deep in the Mariana Trench. That’s the deepest point in the ocean at slightly over 36,000 feet deep. That’s 6.8 miles.
Have we ever reached the bottom of the ocean?
It’s been a record-breaking expedition in more ways than one. Vescovo’s trip to the Challenger Deep, at the southern end of the Pacific Ocean’s Mariana Trench, back in May, was said to be the deepest manned sea dive ever recorded, at 10,927 meters (35,853 feet).
What happens if you go to far down in the ocean?
Dive down into the ocean even a few feet, though, and a noticeable change occurs. You can feel an increase of pressure on your eardrums. … The deeper you go under the sea, the greater the pressure of the water pushing down on you. For every 33 feet (10.06 meters) you go down, the pressure increases by one atmosphere .
At what depth will water crush you?
At about 10–12 meters (33–40 feet) of depth, pressure of water column above you (1 extra atmosphere of pressure per 10 meters) will compress air spaces in your body by half, with lungs compressing the most by the absolute volume.
How deep underwater can a human go?
The deepest point ever reached by man is 35,858 feet below the surface of the ocean, which happens to be as deep as water gets on earth. To go deeper, you’ll have to travel to the bottom of the Challenger Deep, a section of the Mariana Trench under the Pacific Ocean 200 miles southwest of Guam.
What is crush depth for a human?
Human bone crushes at about 11159 kg per square inch. This means we’d have to dive to about 35.5 km depth before bone crushes. This is three times as deep as the deepest point in our ocean.
What is the deepest sea on earth?
The world’s deepest oceans and seas
|Ocean / Sea||Max depth (m)|
Do we know how deep the ocean is?
Today scientists know that on average the ocean is 2.3 miles (3.7 km) deep, but many parts are much shallower or deeper. To measure depth they use sonar, which stands for Sound Navigation And Ranging.
Why can’t we go deep in the ocean?
The main reason is deep sea is finite whereas Outer space is infinite. Getting humans down to the deepest areas is exceedingly difficult due to extreme pressures. All that pressure makes deep sea exploration logistically very difficult and extremely dangerous. but with use of science we overcome.
Can oceans be drained?
Not much. It would actually take hundreds of thousands of years for the ocean to drain. Even though the opening is wider than a basketball court, and the water is forced through at incredible speeds, the oceans are huge.
What lives at the bottom of the ocean?
Life In the Shadowy Depths
From frightful fangtooth fish and vampire squid to coffinfish and spiky, sinister sea urchins, plenty of strange and scary creatures lurk in the dark, cold depths of the ocean … Be brave and dive on in!
How far down is the Titanic?
The ship, which fell to the seabed in two parts, can now be found 370 miles off the coast of Newfoundland at a depth of roughly 12,600 feet.
Can water pressure kill you?
The pressure of the water on a deep-diver’s body can crush him. It can easily cause death. Coming up from the extreme pressure of deep water to the much lower pressure at the surface is especially dangerous. Ascending too quickly can cause a fatal condition called “the bends.”
How cold is it at the bottom of the ocean?
Therefore, the deep ocean (below about 200 meters depth) is cold, with an average temperature of only 4°C (39°F). Cold water is also more dense, and as a result heavier, than warm water. Colder water sinks below the warm water at the surface, which contributes to the coldness of the deep ocean.
