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.
Challenger Deep is the deepest point in the world ocean. Located within the already-deep Mariana Trench in the western Pacific Ocean, the actual deepness of Challenger Deep strains the imagination. We'll take a look at some bizarre ways to consider this depth, but first we'll explore why Challenger Deep...is deep.
The Mariana Trench, in the Pacific Ocean, is the deepest location on Earth. According to the Exclusive Economic Zone (EEZ), the United States has jurisdiction over the trench and its resources. Scientists use a variety of technologies to overcome the challenges of deep-sea exploration and explore the Trench.
Last year an expedition to the Mariana Trench made history by conducting the deepest crewed dive ever completed as it descended 10,927 metres into the Challenger Deep.
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.
More than eighty percent of our ocean is unmapped, unobserved, and unexplored. Much remains to be learned from exploring the mysteries of the deep.
While the recommended maximum depth for conventional scuba diving is 130 feet, technical divers may work in the range of 170 feet to 350 feet, sometimes even deeper.
Scientists haven't yet determined a hard limit for how deep we can survive underwater. There have been a few instances of divers surviving ridiculous depths (not without side effects), but most professional free divers don't go past 400 feet deep.
One species of bacteria, "Candidatus Desulforudis audaxviator", is the first known to comprise a complete ecosystem by itself. It was found 2.8 kilometers below the surface in a gold mine near Johannesburg, South Africa.
Based on the known temperature limit for life, which Geib reports is some 250 degrees Fahrenheit, the researchers discovered that life could survive up to six miles below the planet's surface.
Only a handful of people have ever visited the bottom of the Mariana Trench, a crescent-shaped depression in the Earth's crust that is deeper than Mount Everest is high and more than 1,600 miles long.
You might expect the waters of the Mariana Trench to be frigid since no sunlight can reach it. And you'd be right. The water there tends to range between 34 to 39 degrees Fahrenheit.
The Mariana Trench is deeper than Mount Everest is tall and anything living there has to survive the cold water and extremely high pressure. Some animals, including the deep-sea crustaceans Hirondellea gigas , do live there —and they have recently had a human visitor.
The whole time, Cameron said, he didn't see any fish, or any living creatures more than an inch (2.5 centimeters) long: "The only free swimmers I saw were small amphipods"—shrimplike bottom-feeders that appear to be common across most marine environments.
The ocean is so deep at the Mariana Trench because of the nearby fault lines the Pacific Plate into a narrow tongue (Figure 3) (Lovett, 2012). Fault lines are breaks or fractures that occur when Earth's tectonic plates move or shift (Your Dictionary).
Too much pressure would collapse those spaces, crushing us. Animals adapted to deep-ocean life don't have air pockets in their bodies. Some marine animals travel between deep ocean and the surface.
The Titanic lies in about 14,000 feet of water in the North Atlantic, a depth that humans can reach only while inside specialized submersibles that keep their occupants warm, dry and supplied with breathable air.
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.
Thousands have climbed Mount Everest, and a handful of people have walked on the moon. But reaching the lowest part of the ocean? Only three people have ever done that, and one was a U.S. Navy submariner.
While there's no precise depth at which a human would be 'crushed', diving beyond certain limits (around 60 meters) without proper equipment and gas mixes can lead to serious health issues due to the pressure effects on the body, including nitrogen narcosis and oxygen toxicity.
Submarines can submerge more than 600 feet below the ocean's surface for up to four months at a time, constantly patrolling and working classified missions. You can't always see them, but they are always silently moving under the sea doing important work.
How Much Treasure is Down There? The short answer, Sean Fisher says, is $60 billion.
In fact, most of the waters remain unexplored, uncharted and unseen by our eyes. It might be shocking to find out, but only 5% of the ocean has been explored and charted by humans. The rest, especially its depths, are still unknown.
“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.
