At this depth, Nereus was able to explore the Challenger Deep — the ocean’s lowest point, located in the Mariana Trench in the western Pacific.

Has anything been to the bottom of the Mariana Trench?
At nearly seven miles below the water’s surface, the Mariana Trench is the deepest spot in Earth’s oceans. And the site north of Guam is where director and explorer James Cameron recently fulfilled a longtime goal of reaching the bottom in a manned craft.
How deep can you dive before being crushed?
To put these depths into perspective, three American football fields laid end to end would measure 900 feet (274.32 m) long — less than the distance these divers reached underwater. Most recreational scuba divers only dive as deep as 130 feet (40 meters), according to the Professional Association of Diving Instructors.
Could there be deeper parts of the ocean?
Its depth is difficult to measure from the surface, but modern estimates vary by less than 1,000 feet (305 meters). In 2010, the Challenger Deep was pegged at 36,070 feet (10,994 m), as measured with sounds pulses sent through the ocean during a 2010 survey by the National Oceanic and Atmospheric Administration (NOAA).
What is the deepest a human has been underground?
The Kola Superdeep Borehole was just 9 inches in diameter, but at 40,230 feet (12,262 meters) reigns as the deepest hole. It took almost 20 years to reach that 7.5-mile depth—only half the distance or less to the mantle.
What animals live at the bottom of the ocean?
- Frilled Shark. Humans rarely encounter frilled sharks, which prefer to remain in the oceans’ depths, up to 5,000 feet (1,500 meters) below the surface.
- Giant Spider Crab.
- Atlantic Wolffish Pair.
- Fangtooth Fish.
- Six-Gill Shark.
- Giant Tube Worms.
- Vampire Squid.

Which is the coldest and smallest ocean in the world?
The Arctic Ocean is the smallest, shallowest, and coldest part of the ocean.
Is Indian Ocean bigger than Arctic Ocean?
Although the Arctic Ocean is by far the smallest of the Earth’s oceans, having only a little more than one-sixth the area of the next largest, the Indian Ocean, its area of 5,440,000 square miles (14,090,000 square km) is five times larger than that of the largest sea, the Mediterranean.
What is the second smallest ocean?
The Southern Ocean is the second smallest of the five named oceans. The Atlantic Ocean, the second biggest, extends from the Southern Ocean between South America, Africa, North America and Europe, to the Arctic Ocean. The Atlantic meets the Indian Ocean south of Africa at Cape Agulhas.

How deep is a shallow sea?
Shallow seas are defined as marginal or inland extensions of ocean with average depths of about 200 m. They are also called coastal or neritic waters, and described as those lying landward of 200 m depth.

Has Marianas Trench been explored?
The Mariana Trench is one of the least explored places on Earth. Deep enough to swallow Mt. Everest, the Mariana Trench was first pinpointed in 1951 by the British Survey ship Challenger II. The Mariana Trench represents just one small part of the Earth’s last, great frontier.
What’s in the ocean we don’t know about?
The ocean is the lifeblood of Earth, covering more than 70 percent of the planet’s surface, driving weather, regulating temperature, and ultimately supporting all living organisms. For the ocean and coastal waters of the United States, only about 35 percent has been mapped with modern methods.
Is there any life in the Mariana Trench?
The New Britain Trench — which Cameron visited as a test-run for Mariana — which at 8,200 meters deep is only 2,700 meters shallower than Challenger Deep. But life there was very different. The trench bottom was home to an array of sea cucumbers,sea anemones, jellyfish, comb jellyfish, and giant amphipods.
What is the pressure 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 1,000 times the standard atmospheric pressure at sea level.
Why is the Mariana trench so deep?
“In order for this to sink back into the earth, it has to bend downward, and these are very gentle bends.” 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.
Has anyone touched the bottom of Mariana Trench?
Monday, local time), James Cameron arrived at the Mariana Trench’s Challenger Deep, members of the National Geographic expedition have confirmed. His depth on arrival: 35,756 feet (10,898 meters)—a figure unattainable anywhere else in the ocean.
Is holding your breath bad for your brain?
Summary: Divers who held their breath for several minutes had elevated levels of a protein that can signal brain damage. However, the appearance of the protein, S100B, was transient and leaves open the question of whether lengthy apnea (breath-holding) can damage the brain over the long term.
How deep has a human been in the ocean?
The Challenger Deep is the deepest known point in the Earth’s seabed hydrosphere (the oceans), with a depth of 10,898 to 10,916 m (35,755 to 35,814 ft) by direct measurement from submersibles and slightly more by sonar bathymetry.

Challenger Deep
Is there a place deeper than the Mariana Trench?
Officially anything deeper than just 200 metres is considered the “deep sea”, but the average depth of the entire ocean is about 3.5km and the deepest point – the Challenger Deep in the Mariana Trench, in the western Pacific – is a little short of 11km down.
What lives in the deepest part of ocean?
The deepest part of the ocean is in the Mariana Trench (sometimes called the Marianas Trench), located in the western Pacific Ocean. Deepest known fish is now a snailfish, the fragile creature to the left of center in this image, at a depth of 8,145 meters in the Mariana Trench.
How far can humans go underground?
Humans have drilled over 12 kilometers (7.67 miles) in the Sakhalin-I. In terms of depth below the surface, the Kola Superdeep Borehole SG-3 retains the world record at 12,262 metres (40,230 ft) in 1989 and still is the deepest artificial point on Earth.
