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.

Why can't we go to the bottom of 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.

Why is the ocean blue?

The ocean is blue because water absorbs colors in the red part of the light spectrum. Like a filter, this leaves behind colors in the blue part of the light spectrum for us to see. The ocean may also take on green, red, or other hues as light bounces off of floating sediments and particles in the water.

Has anyone been to bottom of Mariana Trench?

On 23 January 1960, two explorers, US navy lieutenant Don Walsh and Swiss engineer Jacques Piccard, became the first people to dive 11km (seven miles) to the bottom of the Mariana Trench. As a new wave of adventurers gear up to repeat the epic journey, Don Walsh tells the BBC about their remarkable deep-sea feat.

What happens to human body in deep sea?

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. ... The nitrogen would bind to the parts of the body that need to use oxygen, and the person would literally suffocate from the inside out.

How dark is the bottom of the ocean?

After the aphotic zone, there's complete darkness. From 1,000 meters below the surface, all the way to the sea floor, no sunlight penetrates the darkness; and because photosynthesis can't take place, there are no plants, either.

How much of the ocean is discovered?

According to the National Ocean Service, it's a shockingly small percentage. Just 5 percent of Earth's oceans have been explored and charted – especially the ocean below the surface. The rest remains mostly undiscovered and unseen by humans.

What is the maximum depth of the ocean?

Who went the deepest in the ocean?

• Deepest Manned Ocean Descent. The deepest ever manned ocean descent was on Janu, when Dr Jacques Piccard (Switzerland) and Lt. Donald Walsh, USN, piloted the US Navy bathyscaphe Trieste to a depth of 10,911 m (35,797 ft) in the Challenger Deep section of the Mariana Trench .

What is the lowest point in the ocean?

• The lowest point on land in the Western Hemisphere is Death Valley in California at 86 meters below sea level. The lowest point on the Earth’s crust is the Mariana’s Trench in the North Pacific Ocean.

How do we know how deep the ocean is?

• The Challenger Deep is the deepest known point in the Earth's seabed hydrosphere, with a depth of 10,898 to 10,916 m (35,755 to 35,814 ft) by direct measurement from submersibles, and slightly more by sonar bathymetry (see below). It is in the Pacific Ocean, at the southern end of the Mariana Trench near the Mariana Islands group.
