## What is the pressure at 2000 meters below the ocean surface?

An ROV diving to a depth of 2,000m experiences over 1,270kg (2,800lbs) of force exerted on each square inch of its surface!

**What is the pressure 2 miles underwater?**

The Titanic is 2 miles below sea level, the water pressure is 25,000 PSI.

**What is the water pressure at 1 mile deep?**

about 2,500 PSI

The water pressure one mile deep in the ocean (about the depth where giant squid seem to live) averages about 2,500 PSI. So if a submarine dove 1 mile deep, every square inch of the outside of its hull would be pressed on by 2,500 pounds of force.

### What is the water pressure at Titanic?

The pressure at such depths in the ocean is about 455 times the atmospheric pressure at sea level. The remains of Titanic are located at a depth of 12,500 feet (3.8 kilometers) depth, which has pressure of about 380 atm. The additional 2,500 feet increases the pressure by 75 atm.

**How do submarines survive water pressure?**

Most submarines have two hulls, one inside the other, to help them survive. The outer hull is waterproof, while the inner one (called the pressure hull) is much stronger and resistant to immense water pressure. The strongest submarines have hulls made from tough steel or titanium.

**At what depth will the ocean crush you?**

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.

#### How far can you go underwater without getting crushed?

**What is the highest PSI ever recorded?**

An international team of scientists has created the highest static pressure ever achieved in a lab: Using a special high pressure device, the researchers investigated the behavior of the metal osmium at pressures of up to 770 Gigapascals — more than twice the pressure in the inner core of the Earth.

**What is the deepest fish ever found?**

The fish that currently holds the depth record is a species of cuskeel (family Ophidiidae) called Abyssobrotula galatheae. This 20 cm long fish has been collected from the Puerto Rico Trench at a depth of 8,370 m (27,455 feet).

## How deep in the ocean Can a human survive?

For most swimmers, a depth of 20 feet (6.09 metres) is the most they will free dive. Experienced divers can safely dive to a depth of 40 feet (12.19 metres) when exploring underwater reefs.
