Why can't we go 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.

Can we go down to the bottom 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.

Has anyone ever went to the bottom of the ocean?

The Challenger Deep is at the bottom of the Mariana Trench in the Pacific Ocean. It has only been reached once before, in 1960 by the explorers Don Walsh and Jacques Piccard.

How deep has a human gone in the ocean?

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).

What is really in the deep ocean?

The abyssal plain is the relatively level deep seafloor. It is a cold and dark place that lies between 3,000 and 6,000 meters below the sea surface. It is also home to squat lobsters, red prawns, and various species of sea cucumbers. For these creatures food is scarce most of the time.

What Did Scientists Really See In The Mariana Trench?

How deep can a human dive before dying?

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 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.

Has anyone been to bottom of Mariana Trench?

The first and only time humans descended into the Challenger Deep was more than 50 years ago. In 1960, Jacques Piccard and Navy Lt. Don Walsh reached this goal in a U.S. Navy submersible, a bathyscaphe called the Trieste.

Are there monsters in the Mariana Trench?

Despite its immense distance from everywhere else, life seems to be abundant in the Trench. Recent expeditions have found myriad creatures living out their lives at the bottom of the sea-floor. Xenophyophores, amphipods, and holothurians (not the names of alien species, I promise) all call the trench home.

What did James Cameron discover in the Mariana Trench?

The discovery of microbial mats — bizarre-looking, filamentlike clumps of microorganisms — living off chemicals from altered rocks 35,803 feet (10,912 meters) beneath the surface of the Pacific Ocean comes from samples and video collected by an unmanned lander, part of movie director James Cameron's mission to the ...

Can a human dive to the Titanic?

You cannot scuba dive to the Titanic due to its depth at 12,500 feet. Air consumption: one standard tank lasts 15 minutes at 120 feet. Supply for 12,500 feet would be impossible to carry even with a team. The deepest dive on record with special equipment, training and a support team is 1,100 feet.

Can you fart while diving?

Farting is possible while scuba diving but not advisable because: Diving wetsuits are very expensive and the explosive force of an underwater fart will rip a hole in your wetsuit. An underwater fart will shoot you up to the surface like a missile which can cause decompression sickness.

Was 47 meters down 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.

Has a shark cage ever dropped?

In 2007, a commercial shark cage was destroyed off the coast of Guadalupe Island after a 4.6-metre (15 ft) great white shark became entangled and tore the cage apart in a frantic effort to free itself. Tourists captured video of the incident, which quickly spread throughout the Internet.

Can you be crushed by water?

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.

Do Cave sharks exist?

Whereas you might get sharks that go into cracks and crevices and little caves, it's always with an exit. They went in, they can get back out again. And so in that sense, there are none that are living in caves. They may use them occasionally for shelter, but certainly not constrained to the cave environment.

What happens if you fart in space?

Surprisingly, that isn't the biggest problem associated with farting in space. Though you're definitely more likely to worsen a small fire when you fart, it won't always injure or kill you. The worst part about farting in space is the lack of airflow. Let's take a step back and remember how farting on Earth works.

Can you fart while sleeping?

People commonly fart in their sleep, although they usually are not aware of it. Research suggests pressure in the anal sphincter muscle ²fluctuates in cycles throughout the day. This muscle is more relaxed during sleep, and it controls whether or not gas present in the large intestine is released.

What happens if you get the bends?

Symptoms can include fatigue and pain in muscles and joints. In the more severe type, symptoms may be similar to those of stroke or can include numbness, tingling, arm or leg weakness, unsteadiness, vertigo (spinning), difficulty breathing, and chest pain. People are treated with oxygen and recompression.

Why were no bodies found on the Titanic?

The state of those bodies would depend on how exposed to currents of oxygenated water — and the deep-sea scavengers that thrive on it — they were over the years. "Decomposition slows if bodies get cut off from the open sea, reducing oxygen levels and scavengers," says William J. Broad in The New York Times.

Can the Titanic ever be raised?

After several trips back to the drawing board, it turns out that raising the Titanic would be about as futile as rearranging the deck chairs on the doomed vessel. After a century on the ocean floor, the Titanic is apparently in such bad shape that it couldn't withstand such an endeavor for various reasons.

Is there anything deeper than the Mariana Trench?

The deepest place in the Atlantic is in the Puerto Rico Trench, a place called Brownson Deep at 8,378m. The expedition also confirmed the second deepest location in the Pacific, behind the Challenger Deep in the Mariana Trench. This runner-up is the Horizon Deep in the Tonga Trench with a depth of 10,816m.

What is at the bottom of the Mariana Trench?

At the bottom of the trench, the water column above exerts a pressure of 1,086 bars (15,750 psi), more than 1,071 times the standard atmospheric pressure at sea level. At this pressure, the density of water is increased by 4.96%. The temperature at the bottom is 1 to 4 °C (34 to 39 °F).

What did James Cameron find at the bottom of Challenger Deep?

In addition to capturing photos and video, Cameron's equipment also took sediment samples. "We did find 68 new species, most of them bacteria," he tells Melissa, "but some small invertebrates, as well, that were brought back." At the spot Cameron visited, the water pressure is more than 16,000 pounds per square inch.
