How deep does the ocean go down?
35,876 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. Challenger Deep is approximately 10,935 meters (35,876 feet) deep.
Has the bottom of the ocean been reached?
2019: Victor Vescovo reached a deeper part of Challenger Deep at 35,853 feet, breaking the record for the deepest dive in DSV Limiting Factor. His dive was part of the Five Deeps Expedition to reach the bottom of every ocean on Earth.
How deep is the ocean in miles?
2.3 miles
The average ocean depth is 3.7 kilometers (2.3 miles).
That’s 2.74 kilometers (1.7 miles) down! The average depth of the ocean is about 3,688 meters (12,100 feet).
What ocean lies next to San Diego?
With 70 miles along the Pacific Ocean, San Diego (California’s second largest city) is divided into six beach regions including Coronado, La Jolla, Mission Bay and Beaches, North County Coastal, South Bay and Point Loma, Harbor Island and Shelter Island.
What’s in the bottom of the ocean?
In addition to minerals, we’ve found unusual animals at the bottom of the ocean. Smithsonian points out that even at 13,000 feet below the surface, where temperatures are near freezing and there’s no sunlight, researchers have discovered living creatures such as fish, coral, crustaceans, jellyfish and worms.
What is under the ocean?
Scientists discover an ocean 400 miles beneath our feet that could fill our oceans three times over. After decades of theorizing and searching, scientists are reporting that they’ve finally found a massive reservoir of water in the Earth’s mantle — a reservoir so vast that could fill the Earth’s oceans three times over
How much pee is in the ocean?
The volume of the Atlantic Ocean is about 350 quintillion liters. That’s 350 and 18 zeroes. If every person on earth had the average amount of pee containing the average amount of urea into the Atlantic, there’d be just 60 parts per trillion of urea in the ocean. That’s nothing, guys.
What is the deadliest sea in the world?
The Cretaceous ocean ranks as the most dangerous sea of all time due to the sheer number and ferocity of its marine predators.
What’s the deepest a human has been 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).
Whats 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 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.
Has anyone reached the 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.

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.
How cold is the bottom of the ocean?
39°F
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.
How deep can you 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.
How much of the Earth is still unexplored?
Most of our world is still shrouded in mystery
Unsurprisingly, we aren’t. In fact, 65% of our planet remains unexplored, most of which lies beneath the oceans. Literally anything could be down there, and we wouldn’t know.
