How deep does the ocean go down?
The average ocean depth is 3.7 kilometers (2.3 miles).
The deepest part of the ocean is called the 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 ...

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.

What is the deepest we have gone down 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).Have we reached the bottom of the ocean?
Only three people have ever done that, and one was a U.S. Navy submariner. In the Pacific Ocean, somewhere between Guam and the Philippines, lies the Marianas Trench, also known as the Mariana Trench. At 35,814 feet below sea level, its bottom is called the Challenger Deep — the deepest point known on Earth.How deep in the ocean until it's dark?
Light in the ocean decreases with depth, with minimal light penetrating between 200-1,000 meters (656-3,280 feet) and depths below 1,000 meters receiving no light from the surface.Why can't Humans 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.This Incredible Animation Shows How Deep The Ocean Really Is
Why is the ocean blue?
The ocean is blue because water absorbs colors in the red part of the light spectrum. Like a filter, this leaves behind colors in the blue part of the light spectrum for us to see. The ocean may also take on green, red, or other hues as light bounces off of floating sediments and particles in the water.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.How much of the ocean is not explored?
More than eighty percent of our ocean is unmapped, unobserved, and unexplored. Much remains to be learned from exploring the mysteries of the deep.Is there an ocean 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 ...Has anyone been to 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.What's in the bottom of the ocean?
The bottom of the deep sea has several features that contribute to the diversity of this habitat. The main features are mid-oceanic ridges, hydrothermal vents, mud volcanoes, seamounts, canyons and cold seeps. Carcasses of large animals also contribute to habitat diversity.What lives in the deepest part of the ocean?

What is hidden in the ocean?
Exotic diamonds blasted from deep within the Earth's mantle are transforming our understanding of our planet. Deep below the surface of our planet, an ocean lurks. It's a secret world of water we only know about because of an unlikely messenger: diamonds.What is beneath the Earth?
Deep in the centre of the planet is the 'inner core', which we think is made of solid iron and nickel. This is surrounded by the 'outer core', which is also made of iron and nickel, but is molten. Convection currents in the outer core create Earth's magnetic field.Which ocean is called Hidden ocean?
Down beneath the mantle is the core, but it's in the mantle that you'll find our secret sixth ocean.How much of Earth is unexplored?
Nasa's space mission is leading us to unexplored depths of our own planet. Our oceans cover more than 70% of the Earth's surface, but over 80% of them remain unexplored.Why is the ocean salty?
From precipitation to the land to the rivers to the seaThe rain physically erodes the rock and the acids chemically break down the rocks and carries salts and minerals along in a dissolved state as ions. The ions in the runoff are carried to the streams and rivers and then to the ocean.
What was found in the ocean recently?
Amazed researchers find mammoth tusk 10,000 feet under the sea. In July 2021, scientists discovered a three-foot-long tusk from an extinct Columbian mammoth some 10,000 feet beneath the ocean. Researchers collected the specimen off the California coast.Can you dive to the Titanic?
You cannot scuba dive to the Titanic due to its depth at 12,500 feet. Air consumption: one standard tank lasts 15 minutes at 120 feet. Supply for 12,500 feet would be impossible to carry even with a team. The deepest dive on record with special equipment, training and a support team is 1,100 feet.How deep can a whale dive?
The deepest recorded dive was 2,992 metres, breaking the record for diving mammals. Experts have suggested that this dive was unusually deep for this species. A more normal depth would be 2,000 metres. Sperm whales also regularly dive 1,000 to 2,000 metres deep.What is the deepest free dive ever?
Deepest no-limits freediveThe record for deepest no-limit freediving is 214m (702ft), held by Austrian world champion Herbert Nitsch, who set the record on 14 June 2007 in Spetses, Greece.
Why is the ocean red?
Ocean water can appear red if there is a bloom of a specific kind of phytoplankton causing a discoloration of the sea surface. These events are called “Red tides.” However, not all red tides are harmful, and they are only considered harmful algal blooms if the type of plankton involved contains hazardous toxins.What is the world's hottest sea?
The hottest ocean area is in the Persian Gulf, where water temperatures at the surface exceed 90 degrees Fahrenheit in the summer. Another hot area exists in the Red Sea, where a temperature of 132.8 degrees Fahrenheit has been recorded at a depth of about 6,500 feet.Why is Caribbean water so clear?
The Caribbean Sea, like other tropical ocean regions, contains warm, clear water. The water is clear due to the absence of plankton and suspended particles.Could there be monsters in the ocean?
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.
