What is the deepest ocean?

The deepest part of the ocean is called the Challenger Deep

Challenger Deep

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

and is located beneath the western Pacific Ocean in the southern end of the Mariana Trench

Mariana Trench

The Mariana Trench or Marianas Trench is 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.

, which runs several hundred kilometers southwest of the U.S. territorial island of Guam. Challenger Deep is approximately 10,935 meters (35,876 feet) deep.

Which is the deepest ocean in the world?

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

How deep is the deepest place 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 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).

Has anyone gone to the bottom of the 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.

Which animal can dive the deepest?

Cuvier's beaked whales (Ziphius cavirostris) are master divers. These creatures hold the record for deepest plunge by a marine mammal. One whale dived to depths of nearly 3,000 meters (almost 1.9 miles). This species also holds the record for the longest dives.

What lives at the bottom of the Mariana Trench?

The three most common organisms at the bottom of the Mariana Trench are xenophyophores, amphipods and small sea cucumbers (holothurians), Gallo said. "These are some of the deepest holothurians ever observed, and they were relatively abundant," Gallo said.

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).

Can submarines go to the bottom of the ocean?

A nuclear submarine can dive to a depth of about 300m. This one is larger than the research vessel Atlantis and has a crew of 134. The average depth of the Caribbean Sea is 2,200 meters, or about 1.3 miles. The average depth of the world's oceans is 3,790 meters, or 12,400 feet, or 2 ¹⁄₃ miles.

Are all oceans connected?

All the oceans are connected to each other. Water is always moving within and between the oceans in currents, tides, and waves. The oceans are so old that, over time, minerals have dissolved into the water that make it taste salty. Much of the salt in the oceans is made of the same stuff as ordinary table salt.

Why is the Mariana Trench so deep?

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. When it's fresh, lava is comparatively warm and buoyant, riding high on the underlying mantle.

Is there deeper than 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 the shallowest ocean?

The Arctic Ocean is not only ranked the smallest in size (it's 10 times smaller than the Pacific Ocean) it's also the shallowest. The average ocean depth according to the National Oceanic and Atmospheric Administration is 2.3 miles (3.7 kilometers) or about 12 100 feet.

Which ocean is coldest?

The Arctic Ocean is the coldest ocean, with average temperatures of about 28°F, but with global warming the arctic is heating twice as fast as the rest of the world. This body of water is also the smallest of the world's oceans. Size: about 5,427,000 square miles. Depth: 3,406 feet on average.

Is there a dragon fish?

dragonfish, also called sea moth, any of about five species of small marine fishes comprising the family Pegasidae and the order Pegasiformes. Dragonfish are found in warm Indo-Pacific waters. They are small (to about 16 centimetres [6 ¹/₂ inches] long), elongated fish encased in bony rings of armour.

How cold is deepest part of ocean?

Therefore, the deep ocean (below about 200 meters depth) is cold, with an average temperature of only 4°C (39°F). Cold water is also more dense, and as a result heavier, than warm water. Colder water sinks below the warm water at the surface, which contributes to the coldness of the deep ocean.

Is there a giant creature in the ocean?

While the blue whale is the overall-largest creature of the sea, the lion's mane jellyfish goes to the top of the list for being the longest. These languid beauties have tentacles that reach an astonishing 120 feet in length. 3 It's hard to know why they are graced with such extraordinary appendages.

How do whales sleep without drowning?

So how can they sleep and not drown? Observations of bottlenose dolphins in aquariums and zoos, and of whales and dolphins in the wild, show two basic methods of sleeping: they either rest quietly in the water, vertically or horizontally, or sleep while swimming slowly next to another animal.

How deep can a human dive before being crushed?

Human bone crushes at about 11159 kg per square inch. This means we'd have to dive to about 35.5 km depth before bone crushes. This is three times as deep as the deepest point in our ocean.

What lives in deepest part of the ocean?

Are megalodons still alive in 2021?

Megalodon is NOT alive today, it went extinct around 3.5 million years ago.

Can we bring back megalodon?

In fact, it's doubtful that they ever will. This is because the megalodon went extinct millions of years ago. And there is no way to bring it back since there's no viable DNA to clone them.

Has a megalodon ever been found?

Fossil remains of megalodon have been found in shallow tropical and temperate seas along the coastlines and continental shelf regions of all continents except Antarctica.
