47 metres in feet is 154 feet, or 47 metres in yards is 51.4 yards.

But however you look at 47 metres down, this is a deep dive.

It is 7 metres beyond the the recreational diver limit of 40 metres..

Can your body explode underwater?

Since your body’s internal pressure is so much less than the ambient pressure, your lungs would not have the strength to push back against the water pressure. At a deep enough level, the lungs would collapse completely, killing you instantly.

Can you dive 1000 feet?

There are different limits set for recreational and commercial divers. With the right scuba gear including a dry dive suit, a scuba tank, gloves, and so on, divers can reach depths of around 1000 feet or more. In fact, with specialized equipment such as an atmospheric suit, divers can reach 2000 feet.

Can water pressure kill you?

The answer is water pressure. The pressure of the water on a deep-diver’s body can crush him. It can easily cause death. … Ascending too quickly can cause a fatal condition called “the bends.”

Are sharks blind?

Are sharks color blind? … Their study shows that although the eyes of sharks function over a wide range of light levels, they only have a single long-wavelength-sensitive cone* type in the retina and therefore are potentially totally color blind.

How deep underwater can humans go without equipment?

For most swimmers, 20 feet is the maximum depth that they will free dive during their lifetime. For experienced divers, they can safely dive to a depth of 30 to 40 feet exploring coral reefs. Beyond 60 feet, your body may start to feel the negative physical effects associated with lack of oxygen and water pressure.

What happens if you go too deep in the ocean?

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.

Can water pressure crush a human?

Human beings can withstand 3 to 4 atmospheres of pressure, or 43.5 to 58 psi. Water weighs 64 pounds per cubic foot, or one atmosphere per 33 feet of depth, and presses in from all sides. The ocean’s pressure can indeed crush you.

Can you dive down to the Titanic?

The Dive. You will journey to the wreck of the Titanic aboard the MIR I or II submersibles. They are capable of reaching ocean depths of 20,000 feet (6,000m). This means they can reach 98% of the ocean floor worldwide.

How deep do navy SEALs dive?

20 feetThe deepest we normally dive as SEALs is under 20 feet. We attack ships and really have no reason to go deeper than the keel of a ship unless a Ship comes over the top of us and forces a “depth excursion” that has us holding the muddy bottom trying to attempt not being sucked into the Ship’s screws.

Is 47 meters a true story?

None of the four teens in the film are based on any particular real person, though in the press notes for the film, director Johannes Roberts says he modeled their relationships after another director’s style.

How deep can a human go underwater before being crushed?

Most recreational scuba divers only dive as deep as 130 feet (40 meters), according to the Professional Association of Diving Instructors.

How far down in the ocean Can a human survive?

In short: most of the body can handle any pressure, but if we’re breathing air the maximum safe depth is about 60 meters (190 feet), the feasible maximum with current technical capabilities (and special breathing gases) is about 500 meters (but, for safety reasons, those depths have only been simulated).

How deep do sharks swim?

6,150 feetThey prefer waters with sea surface temperatures of 50 to 72 degrees Fahrenheit. White sharks have been known to swim as deep as 6,150 feet.

Is last breath a true story?

Chris Lemons’ story has been made into a documentary film A North Sea diver cheated death after a catastrophic computer failure saw his boat drift away and his oxygen supply cut off. … His extraordinary true story has been made into a documentary film, Last Breath.

At what depth will water pressure kill you?

In short: most of the body can handle any pressure, but if we’re breathing air the maximum safe depth is about 60 meters (190 feet), the feasible maximum with current technical capabilities (and special breathing gases) is about 500 meters (but, for safety reasons, those depths have only been simulated).

Why can’t divers go too deep?

Divers breathe compressed air that contains nitrogen. At higher pressure under water, the nitrogen gas goes into the body’s tissues. … Nitrogen narcosis: 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.
