Lying over 35,000 feet down below the waves of the western Pacific, Challenger Deep is – as far as we currently know – the deepest abyss in the world’s oceans.

What is the deepest abyss in the world?

The Mariana Trench, in the Pacific Ocean, is the deepest location on Earth.

What is the deepest abyss in the ocean?

The Challenger Deep in the Mariana Trench is the deepest known point in Earth’s oceans. In 2010 the United States Center for Coastal & Ocean Mapping measured the depth of the Challenger Deep at 10,994 meters (36,070 feet) below sea level with an estimated vertical accuracy of ± 40 meters.

How many miles deep is the abyss?

The Laurentian fan or Laurentian abyss is an underwater depression off the eastern coast of Canada in the Atlantic Ocean. Not a trench, but more of an “underwater valley”, it is estimated to be at most ~19,685 feet (3.7 miles; 6.0 km) in depth.

Is there anything deeper than Challenger Deep?

Challenger Deep is about 36,000 feet, but several trenches have spots over 34,000 feet deep, including the Tonga Trench, the Philippine Trench, the Kuril-Kamchatka Trench. … When numbers are this close, we can’t say for sure that none of these trenches have deeper spots than Challenger Deep.

At what depth will water crush you?

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.

What lives in the abyss?

Blind shrimp, giant white crabs, and a variety of tubeworms are just some of the more than 300 species of vent life that biologists have identified since scientists first blundered upon this otherworldly community two decades ago.

Is there an abyss in the ocean?

The abyssal zone or abyssopelagic zone is a layer of the pelagic zone of the ocean. “Abyss” derives from the Greek word ἄβυσσος, meaning bottomless. … It covers 83% of the total area of the ocean and 60% of the Earth’s surface.

How Far Has anyone 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 would happen if you were teleported to the bottom of the ocean?

So nothing would happen if you were teleported to the bottom of the Mariana Trench for one nanosecond, although you may come back wet. Short answer: Not much. Light, which travels at just over 186,000 miles per second in a vacuum, only travels about one foot in a nanosecond.

Is it pitch black at the bottom of the ocean?

It’s dark down there at the bottom of the sea—darker than you can probably even imagine! Let me explain… The ocean is very, very deep; light can only penetrate so far below the surface of the ocean. As the light energy travels through the water, the molecules in the water scatter and absorb it.

Why are trenches so deep?

Trenches are formed by subduction, a geophysical process in which two or more of Earth’s tectonic plates converge and the older, denser plate is pushed beneath the lighter plate and deep into the mantle, causing the seafloor and outermost crust (the lithosphere) to bend and form a steep, V-shaped depression.

What is the deepest darkest place on earth?

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. The Mariana Trench is one of the least explored places on Earth.

Why is the Challenger Deep so deep?

The great depth of the Challenger Deep is due to active steepening of the subducting slab along a zone of weak coupling with the overriding plate in the southern part of the Mariana Trench tearing away from the northern part (Fryer et al., 2003; Gvirtzman and Stern, 2004). …

Has anyone ever made it to the bottom of the ocean?

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.
