Can you get to the bottom of the deepest ocean?

While thousands of climbers have successfully scaled Mount Everest, the highest point on Earth, only two people have descended to the planet's deepest point, the Challenger Deep

Challenger Deep

The Challenger Deep is the deepest known point of the seabed of Earth, with a depth of 10,902–10,929 m (35,768–35,856 ft) by direct measurement from deep-diving submersibles, remotely operated underwater vehicles and benthic landers, and (sometimes) slightly more by sonar bathymetry.

in the Pacific Ocean's Mariana Trench

Mariana Trench

The Mariana Trench is an oceanic trench located in the western Pacific Ocean, about 200 kilometres (124 mi) east of the Mariana Islands; it is the deepest oceanic trench on Earth. It is crescent-shaped and measures about 2,550 km (1,580 mi) in length and 69 km (43 mi) in width.

What happens if you try to go to the bottom of the ocean?

Below 100 feet deep, divers can experience nitrogen narcosis, a condition that makes them feel and appear uncomfortably drunk or dazed. Even if that wasn't an issue, if you were to go thousands of feet below the surface of the ocean, the pressure is so extreme that it would crush you to death, explains Smallwood.

Is it possible to reach the depth of the ocean?

The deepest point ever reached by man is 35,858 feet below the surface of the ocean, which happens to be as deep as water gets on earth. To go deeper, you'll have to travel to the bottom of the Challenger Deep, a section of the Mariana Trench under the Pacific Ocean 200 miles southwest of Guam.

Why can't we dive to the bottom of the ocean?

“The intense pressures in the deep ocean make it an extremely difficult environment to explore.” Although you don't notice it, the pressure of the air pushing down on your body at sea level is about 15 pounds per square inch. If you went up into space, above the Earth's atmosphere, the pressure would decrease to zero.

Could a human dive to the Mariana Trench?

It is the third time humans have reached the ocean's extreme depths. The first dive to the bottom of the Mariana Trench took place in 1960 by US Navy lieutenant Don Walsh and Swiss engineer Jacques Piccard in a vessel called the bathyscaphe Trieste.

What You'd Feel in the Deepest Ocean Bottom

How much of the ocean is unexplored?

More than 80 percent of the ocean has never been mapped, explored, or even seen by humans. A far greater percentage of the surfaces of the moon and the planet Mars has been mapped and studied than of our own ocean floor. Although there is much more to learn, oceanographers have already made some amazing discoveries.

What if we fall in Mariana Trench?

Any air filled crevice of the human body would collapse in the blink of an eye under this pressure. Lungs filled with air would collapse and the bones would crush. Mariana Trench is the deepest location in earth's crust.

Has a human reached the bottom of the ocean?

But reaching the lowest part of the ocean? Only three people have ever done that, and one was a U.S. Navy submariner. In the Pacific Ocean, somewhere between Guam and the Philippines, lies the Marianas Trench, also known as the Mariana Trench.

Have we touched the very bottom of the ocean?

While thousands of climbers have successfully scaled Mount Everest, the highest point on Earth, only two people have descended to the planet's deepest point, the Challenger Deep in the Pacific Ocean's Mariana Trench.

How dark is the bottom of the ocean?

Light may be detected as far as 1,000 meters down in the ocean, but there is rarely any significant light beyond 200 meters. The ocean is divided into three zones based on depth and light level.

At what depth of sea can a human survive?

That means that most people can dive up to a maximum of 60 feet safely. 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.

Is there a place deeper than Mariana Trench?

Challenger Deep is the deepest point in the world ocean. Located within the already-deep Mariana Trench in the western Pacific Ocean, the actual deepness of Challenger Deep strains the imagination. We'll take a look at some bizarre ways to consider this depth, but first we'll explore why Challenger Deep...is deep.

What happens to blood in the ocean?

Without red color in the sunlight, only green light reflects from the blood. This fact can be startling to divers who get a cut while diving. Again, the blood does not change when in the deep ocean. Rather, the green color of blood that is always there becomes obvious once the brighter red color is no longer present.

Is there an ocean under the ocean?

Hidden inside the Earth—within the first several hundred kilometers below the crust—there is another ocean. It is, most likely, the largest ocean in the world. This water is not sloshing around in a big pool.

Is 95 of the ocean unexplored?

It's often said that 95% of the Earth's ocean floor is unexplored. The National Oceanic and Atmospheric Association (NOAA) puts that figure at more than 80%.

How far underground have humans gone?

Humans have drilled over 12 kilometers (7.67 miles) in the Sakhalin-I. In terms of depth below the surface, the Kola Superdeep Borehole SG-3 retains the world record at 12,262 metres (40,230 ft) in 1989 and still is the deepest artificial point on Earth.

How much of Earth is unexplored?

In fact, 65% of our planet remains unexplored, most of which lies beneath the oceans. Literally anything could be down there, and we wouldn't know.

What parts of the ocean are unexplored?

According to Oceana, more than 80 percent of the ocean still remains unexplored. It might seem a rather large number, considering that humankind has explored and settled in every other corner of the globe and beyond, but the deepest parts of the ocean are largely inaccessible by we who breathe oxygen to survive.

Who has touched the bottom of the ocean?

Piccard, Walsh and Cameron remained the only people to reach the world's deepest seafloor until 2019, when regular dives in DSV Limiting Factor began. By November 2022, a total of twenty-two dives had reached Challenger Deep, of which nineteen had been in Limiting Factor. Astronaut Kathryn D.

Can a human survive in the middle of the ocean?

Assuming you're in warm waters and wearing a wetsuit and life vest, you could potentially survive for as many as three to five days, at which point you'll most likely succumb to dehydration. That is, unless a shark gets you first.

Who has gone the deepest in the ocean?

Explorer and businessman Victor Vescovo descended 35,853 feet (10,927 meters) into the Pacific Ocean, breaking the record for deepest dive ever. At the very bottom, he found colorful rocky structures, weird critters and the ever-pervasive mark of humankind — plastic.

What is the darkest part of the ocean?

Mariana Trench. Imagine the deepest, darkest place on Earth—an underwater trench plummeting to a depth of 35,800 feet, nearly seven miles below the ocean surface.

How far has a human gone in the Mariana Trench?

Vescovo's trip to the Challenger Deep, at the southern end of the Pacific Ocean's Mariana Trench, back in May, was said to be the deepest manned sea dive ever recorded, at 10,927 meters (35,853 feet).

Can the ocean pressure crush you?

Water cannot be compressed, or squeezed, by pressure like air can. This means that animals in the sea can stay safe when in the depths of the sea, as their body is balanced with the pressure around them, whereas we have air in our bodies that would be crushed.
