With an area of about 6.1 million square miles , the Arctic Ocean is about 1.5 times as big as the United States. It is bordered by Greenland, Canada, Norway, Alaska, and Russia. The average depth of the Arctic Ocean is 3,953 feet and it is 18,264 feet at its deepest point.
What is the lowest depth in the ocean?
At 35,814 feet below sea level, its bottom is called the Challenger Deep — the deepest point known on Earth.
What is the shallowest ocean in the world?
The Arctic Ocean is the smallest and shallowest of the world’s five major oceans.
What ocean is the darkest?
WESTERN PACIFIC
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.
Which is the first deepest ocean?
That’s 1.7 miles down! The average depth of the ocean is about 12,100 feet . 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.
How deep can a human go underwater?
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.
What lives at the bottom of the ocean?
However, there are more than 200 species of anglerfish, divided into four groups: goosefish, batfish, frogfish, and deep-sea angler. Only females possess the iconic, bioluminescent angling apparatus. Most live at the bottom of the Atlantic and Antarctic Oceans, sometimes as far as a mile below the surface.
Which is the cleanest ocean?
Which Ocean is the Cleanest?
| Rank | Ocean | Pollution Particles (Est) |
|---|---|---|
| 1 | South Atlantic | 297 Billion |
| 2 | South Pacific | 491 Billion |
| 3 | North Atlantic | 930 Billion |

Which ocean is coldest?
The Arctic Ocean is the smallest, shallowest, and coldest part of the ocean.
What is the smallest sea?
Sea of Marmara
Which sea is actually the smallest on Earth is somewhat disputed. However, many people agree that the smallest sea is probably the Sea of Marmara in Turkey. This sea is about 7,053 square feet large. It is an inland sea, and connects the Aegean Sea and the Black Sea.
At what depth is the ocean dark?
It is sometimes referred to as the midnight zone or the dark zone. This zone extends from 1,000 meters (3,281 feet) down to 4,000 meters (13,124 feet). Here the only visible light is that produced by the creatures themselves. The water pressure at this depth is immense, reaching 5,850 pounds per square inch.
Is the dark sea real?
The Black Sea, also known as Euxine Sea, is one of the major water bodies and a famous inland sea of the world. This marginal sea of the Atlantic Ocean, located between Eastern Europe and Western Asia, has become legendary for long period of time.
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. … Below the photic zone, from 200 to 1,000 meters, is the aphotic (a meaning without and photic meaning light) zone.
Can we reach the bottom of the ocean?
It’s been a record-breaking expedition in more ways than one. 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 the largest ocean?
The Pacific Ocean is the largest and deepest of the world ocean basins. Covering approximately 63 million square miles and containing more than half of the free water on Earth, the Pacific is by far the largest of the world’s ocean basins.
Who reached first in Mariana Trench?
Four manned descents and three unmanned descents have been achieved. The first was the manned descent by Swiss-designed, Italian-built, United States Navy-owned bathyscaphe Trieste, which reached the bottom at 1:06 pm on 23 January 1960, with Don Walsh and Jacques Piccard on board.
