What happens to body at 13,000 feet underwater?
Without the protection of a specialized submersible, the intense pressure would instantly crush a human. At these abyssal depths, the human body cannot function, as the crushing force would collapse lungs and cause other organs to fail.
The human body would also be subject to traumatic injury due to the sudden change in pressure, resulting in an instantaneous or near-instantaneous death. Can humans survive a submarine implosion at 13,000 feet underwater? Survival is nearly impossible in this scenario.
These vessels are equipped to travel the 13,000 feet down to the Titanic and withstand the 6,000 pounds per square inch of pressure.
While there's no precise depth at which a human would be 'crushed', diving beyond certain limits (around 60 meters) without proper equipment and gas mixes can lead to serious health issues due to the pressure effects on the body, including nitrogen narcosis and oxygen toxicity.
Over time, the bodies will decompose in a process distinctly different from terrestrial decomposition. Factors like the low temperatures, high pressure, and absence of sunlight play pivotal roles in this deep-sea decomposition process.
And if the body is floating in water less than 70 degrees Fahrenheit (21 degrees Celsius) for about three weeks, the tissues turn into a soapy fatty acid known as "grave wax" that halts bacterial growth. The skin, however, will still blister and turn greenish black.
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.
The wreck sits in the dark bathypelagic, or midnight, zone, at a spot 12,400 feet below the ocean's surface. The pressure around the famous sunken ship is about 375 atmospheres. That means every square inch of an object's surface experiences the equivalent of 5,500 pounds of force.
The pressure from the water would push in on the person's body, causing any space that's filled with air to collapse. (The air would be compressed.) So, the lungs would collapse. At the same time, the pressure from the water would push water into the mouth, filling the lungs back up again with water instead of air.
The body would be subjected to rapid compression, causing immediate and severe trauma. Essentially, every part of the body that contains gas, including the lungs and the gastrointestinal tract, would be crushed or imploded. The water pressure would also force water into body cavities such as the nose, mouth, and ears.
What happens if a human goes too deep in the ocean?
Some people may even lose consciousness, because the water pressure increases as you go deeper and deeper. Even scuba divers with special protective equipment and air compressers can go upto maximum of 150m depth. Anything above 150m deep, the water pressure will kill you and break your lungs and bones.
The reason for this is that if a submarine implodes, there is zero chance anyone could survive. Their bodies would have been instantly annihilated by the pressure change, and anything that did remain would sink to the bottom of the ocean.
For most swimmers, a depth of 20 feet (6.09 meters) is the most they will free dive. Experienced divers can safely dive to a depth of 40 feet (12.19 meters) when exploring underwater reefs. When free diving the body goes through several changes to help with acclimatization.
Contrary to wild speculation that you'd be flattened or crushed up like a can and your bones reduced to gravel, surprisingly little — you'd still be recognizable, until the scavengers get to work. You could last long enough before you pass out to experience the pressure cracking your ribs, though.
After five to ten minutes of not breathing, you are likely to develop serious and possibly irreversible brain damage. The one exception is when a younger person stops breathing and also becomes very cold at the same time. This can occur when a child is suddenly plunged into very cold water and drowns.
Bodies have been retrieved almost completely intact from waters below 7°C after several weeks, and as recognisable skeletons after five years. In tropical waters such as the Arabian sea, it's a different story.
Putrefaction - which is the process of a body decaying - will allow scavenging creatures to pick apart the corpse within two weeks, with any remaining bones then sinking to the seabed.
Your muscles loosen immediately after death, releasing any strain on your bowel and bladder. As a result, most people poop and pee at death. Your skin may also sag, making it easier to see your bone structure beneath. Your temperature drops.
The Return of the Dead
The Chinese believe the soul of the deceased returns to his or her home seven days after death. To ensure the soul finds its way, a red plaque bearing an inscription is placed outside the home.
Smith perished that night along with around 1,500 others, and his body was never recovered.
Are there still human bones on the Titanic?
Bottles of wine, shoes, suitcases are among the items that can be seen strewn across the ocean floor, reminders of lives that were cut short by the icy Atlantic waves. But, crucially, plenty is still missing: human remains. Some 1,160 people went down with the Titanic. but no bodies have ever been found.
Of the 337 bodies recovered, 119 were buried at sea. 209 were brought back to Halifax. 59 were claimed by relatives and shipped to their home communities. The remaining 150 victims are buried in three cemeteries: Fairview Lawn, Mount Olivet and Baron de Hirsch.
Titanic, Inc. (RMST), continues to have the right to salvage the wreck but does not own it or any artifacts recovered from the wreck site unless and until the Court specifically grants title to the recovered artifacts.
At approximately 2:18 am the lights on the Titanic went out. It then broke in two, with the bow going underwater. Reports later speculated that it took some six minutes for that section, likely traveling at approximately 30 miles (48 km) per hour, to reach the ocean bottom.
"But it will never come out," Daniel Stone wrote in "Sinkable: Obsession, the Deep Sea, and the Shipwreck of the Titanic." "Not only is the exposed steel on the upper bow too brittle for even the most industrious crane operation, but the mud has also acted as deep-sea quicksand for longer than most humans have been ...
