What happens to a human body at 12000 feet underwater

Even at this depth, the lungs of many humans collapse as they are unable to move against the pressure. The immense amount of ambient pressure from the water is so much greater than the body's internal pressure, so the lungs would collapse completely, resulting in instant death.

What is the crush depth of a human

You would have to dive to around 35.5km of depth before you were crushed because human bone crushes at approximately 11159kg per square inch, which is pressure that you wouldn't experience in a casual dive.

How deep can a human go underwater without dying

around 60 feet

The maximum depth a human can dive without oxygen is around 60 feet (18 meters). Beyond this depth, the body requires a supply of oxygen to function properly.

Is the Titanic too deep to dive to

The Titanic is a whopping 2 and a half miles beneath the surface — far too deep for a human to survive the pressure if not in an equipped vessel. Still, there are other parts of the ocean that are even deeper, and many parts yet to be explored.

Can you survive 5 minutes underwater

But the health event we know as drowning only takes a couple of seconds to occur. If a person is submerged after breathing in water for 4 to 6 minutes without resuscitation, it will result in brain damage and eventually death by drowning.

Why can’t humans go to the bottom of the ocean

At a kilometre under sea level, the pressure is 1,500 pounds per square inch. That's like the weight of a small car pushing on every square inch. Enough to kill you. So you can see how even machines have to be incredibly tough to be able to withstand that pressure without crumpling like an old pop can.

Can deep diving crush you

Water won't crush your whole body but after the 1,000 feet (305m) mark, your body would find it extremely difficult to breathe. A bit further below that depth, your ribcage would most likely break.

Can you scuba dive to the Titanic

“A lot of people would like to do it, but diving on the Titanic is a complex and difficult undertaking, with currents up to 4 knots. Even though our onboard team has over 200 Titanic dives to their credit, we cannot take anything for granted.

What is the deepest dive with oxygen

The depth limitations of air as a diving gas

Divers must limit their oxygen exposure to avoid CNS toxicity, which equates to a 56.6m/185ft maximum depth when breathing air (21% O2).

Why can’t the Titanic be raised

Now it turns out that the Titanic will stay where it is, at least for now, as it is too fragile to be raised from the ocean floor. The acidic salt water, hostile environment and an iron-eating bacterium are consuming the hull of the ship.

What is deeper than the Titanic

Perhaps the most intriguing of these features is the Mariana Trench — a chasm in the western Pacific Ocean that spans more than 1,580 miles (2,540 kilometers) and is home to the Challenger Deep, the deepest known point on Earth's surface that plunges more than 36,000 feet (about 11,000 meters) underwater.

How long can a 7 year old hold their breath

Breath-holding is usually harmless

usually last for less than 1 minute (if the child faints, they'll usually regain consciousness within 1 or 2 minutes)

What is the longest breath hold

24 minutes and 37 seconds

The current world record for breath holding, using a technique that is likely the same one the actor employed, is 24 minutes and 37 seconds.

Can you survive at the ocean floor

You can't breath at the bottom of the ocean. 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.

Who lives at the bottom of the ocean

Here is a list of creatures that live at the bottom of the ocean:Tripod fish.Rattail fish.Sea cucumbers.Octopuses.Snailfish.Zombie worms.Dragonfish.Goblin shark.

What happens if a human dive too deep

Deep dives can cause so much nitrogen to build up in the brain that you can become confused and act as though you've been drinking alcohol. You might make poor decisions, such as taking out your regulator because you think you can breathe underwater. Narcosis usually happens only on dives of more than 30 m (100 ft).

Why does the ocean crush you

This is due to an increase in hydrostatic pressure, the force per unit area exerted by a liquid on an object. 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 .

Is it possible to survive Titanic water

There were a few people who did survive the frigid ocean without lifeboats. The most incredible recorded case was of the chief baker, Charles John Joughin, who survived long enough to be pulled into a boat. Interestingly, when he found out the Titanic was sinking, he poured himself a final drink.

Do divers breathe 100% oxygen

On the deepest working dives, at depths greater than 600 m, ambient pressure is greater than 6100 kPa and the divers breathe gas mixtures containing about 2% oxygen to avoid acute oxygen toxicity.

Has anyone dived to the Titanic

“The Titanic was the Mount Everest of shipwrecks, and as a diver I wanted to do it right,” he said. Cameron got the deep-sea diving bug and eventually made more than 70 submersible dives, including 33 to the Titanic, logging more hours on that ship than Capt. Edward Smith himself, according to National Geographic.

Why didn’t Titanic turn left

Why Did Titanic Not Turn Quickly Enough After spotting the iceberg, William Murdoch gave the order to stop the engines and to make a hard left turn. Due to the size and speed of the Titanic it was not able to avoid the iceberg.

Will the Titanic eventually disappear

"Yes, like all things, eventually, Titanic will vanish entirely. It will take a long time before the ship completely disappears, but the decomposition of the wreck is to be expected and is a natural process," Patrick Lahey, president and co-founder of Triton Submarines, told Business Insider.

What ship sunk the deepest

The U.S.S. Samuel B Roberts

World's Deepest Shipwreck Discovered Four Miles Underwater in the Philippines. The U.S.S. Samuel B Roberts, also known as the “Sammy B,” was discovered in the Philippine Sea at a depth of 22,916 feet last week by a team of explorers. The wreck is the deepest ever found, per the Associated Press.

How deep is Titanic lying

about 12,500 feet

The wreck of the Titanic lies at a depth of about 12,500 feet (3,800 metres; 2,100 fathoms), about 370 nautical miles (690 kilometres) south-southeast off the coast of Newfoundland. It lies in two main pieces about 2,000 feet (600 m) apart.

Will babies cry if they can’t breathe

If a baby is breathing stale air and not getting enough oxygen, the brain usually triggers the baby to wake up and cry to get more oxygen.
