The Mariana Trench is a crescent-shaped trench in the Western Pacific, just east of the Mariana Islands near Guam.

Where are the deepest places on Earth?

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.

Is there a place deeper than Mariana Trench?

The ocean is deep. In fact, most of it is deep. Officially anything deeper than just 200 metres is considered the “deep sea”, but the average depth of the entire ocean is about 3.5km and the deepest point – the Challenger Deep in the Mariana Trench, in the western Pacific – is a little short of 11km down.

What bird can dive the deepest below sea level?

The deepest underwater dive by a flying bird is 210 m (690 ft) by a Brünnich’s guillemot or thick-billed murre (Uria lomvia) with a maximum speed of descent of around 2 m (6 ft 6 in) a second. Auks in general are excellent swimmers and recent technology has made tracking the depth of their dives much easier.

How deep can you dive before being crushed?

To put these depths into perspective, three American football fields laid end to end would measure 900 feet (274.32 m) long — less than the distance these divers reached underwater. Most recreational scuba divers only dive as deep as 130 feet (40 meters), according to the Professional Association of Diving Instructors.

What is at the bottom of the deepest ocean?

The deepest part of the ocean is called the Challenger Deep and is located beneath the western Pacific Ocean in the southern end of the Mariana Trench, which runs several hundred kilometers southwest of the U.S. territorial island of Guam. Challenger Deep is approximately 36,200 feet deep.

Is there any life in the Mariana Trench?

The New Britain Trench — which Cameron visited as a test-run for Mariana — which at 8,200 meters deep is only 2,700 meters shallower than Challenger Deep. But life there was very different. The trench bottom was home to an array of sea cucumbers,sea anemones, jellyfish, comb jellyfish, and giant amphipods.

Why did Megalodons become extinct?

An earlier extinction date puts megalodon’s fall in line with the rise of the great white. The largest shark that ever lived, the prehistoric—and certainly extinct—megalodon, might have been driven to extinction by a smaller and nimbler competitor that still roams the seas today: the great white shark.

Has anyone been to the bottom of the Mariana Trench?

At nearly seven miles below the water’s surface, the Mariana Trench is the deepest spot in Earth’s oceans. And the site north of Guam is where director and explorer James Cameron recently fulfilled a longtime goal of reaching the bottom in a manned craft.

How deep can you dive without having to decompress?

The need to do decompression stops increases with depth. A diver at 6 metres (20 ft) may be able to dive for many hours without needing to do decompression stops. At depths greater than 40 metres (130 ft), a diver may have only a few minutes at the deepest part of the dive before decompression stops are needed.

Why is the Mariana trench so deep?

“In order for this to sink back into the earth, it has to bend downward, and these are very gentle bends.” One reason the Mariana Trench is so deep, he added, is because the western Pacific is home to some of the oldest seafloor in the world—about 180 million years old. Seafloor is formed as lava at mid-ocean ridges.

Can penguins dive deeper than whales?

Whales hold the deep-diving record for air-breathers, but they do get the bends, too. Seals, which can dive even deeper than the emperors, avoid this condition because they deflate their lungs when they go down.

What happens if a diver ascends too quickly?

Decompression sickness: Often called “the bends,” decompression sickness happens when a scuba diver ascends too quickly. But if a diver rises too quickly, the nitrogen forms bubbles in the body. This can cause tissue and nerve damage. In extreme cases, it can cause paralysis or death if the bubbles are in the brain.

How deep can a free diver go?

There’s free diving with weights, free diving without weights, free diving with fins, and so on and so forth. But right now the world record for no limits—a crazy discipline in which guys rig themselves onto machines and the machines take them down to depths very quickly—is 700 feet.

Could there be deeper parts of the ocean?

Its depth is difficult to measure from the surface, but modern estimates vary by less than 1,000 feet (305 meters). In 2010, the Challenger Deep was pegged at 36,070 feet (10,994 m), as measured with sounds pulses sent through the ocean during a 2010 survey by the National Oceanic and Atmospheric Administration (NOAA).

Have we explored the deepest part of the ocean?

A robotic vehicle named Nereus has made one of the deepest ocean dives ever — 6.8 miles (10,902 meters), a team of scientists and engineers reported yesterday. At this depth, Nereus was able to explore the Challenger Deep — the ocean’s lowest point, located in the Mariana Trench in the western Pacific.
