What was found in the Challenger Deep?

In April 2019, American undersea explorer Victor Vescovo set a new record for the deepest descent ever at the Challenger Deep - 35,853 feet (10,928 meters). On the bottom of the ocean, he found candy wrappers and plastic bags.

What did they see at the bottom of the Challenger Deep?

They saw arrowtooth eels at 9,843 feet (3,000 m) and a wriggly little spoon worm (Echuria) at 22,966 feet (7,000 m). At 26,247 feet (8,000 m), they observed Mariana snailfish and supergiant amphipods (Alicella species) — creatures about 20 times larger than typical amphipods.

What did they find at the bottom of the Mariana Trench?

But if you thought the trench could escape the global onslaught of plastics pollution, you would be wrong. A recent study revealed that a plastic bag, like the kind given away at grocery stores, is now the deepest known piece of plastic trash, found at a depth of 10,975 meters (36,000 feet) inside the Mariana Trench.

Is there life at the bottom of Challenger Deep?

Researchers from Japan have found that bacteria thrive in the canyon called Challenger Deep, which is the lowest point on Earth's ocean floor and the deepest part of the Mariana Trench.

What would happen to the human body in Challenger Deep?

The pressure from the water would push in on the person's body, causing any space that's filled with air to collapse. (The air would be compressed.) So, the lungs would collapse.

Mariana Trench: Record-breaking journey to the bottom of the ocean - BBC News

Are there monsters in the Mariana Trench?

Despite its immense distance from everywhere else, life seems to be abundant in the Trench. 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.

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.

How cold is the water in the Challenger Deep?

It's Hot and It's Cold

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.

How far down is 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.

What lives in Challenger Deep?

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.

What's inside Mariana Trench?

The Mariana Trench is the deepest point on Earth, void of light with the pressure of 48 jumbo jets. You'll still find crustaceans, translucent snailfish, and sea cucumbers in it. The most surprising thing in the deep ocean is plastic. Visit Business Insider's homepage for more stories.

Is there anything deeper than the Mariana Trench?

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.

Is the bottom of the Mariana Trench hot?

Due to the absence of sunlight, the Mariana Trench temperature is extremely cold, which fills around 34 – 39 degrees Fahrenheit. Yet, some spots are quite heated. There are hydrothermal vents that discharge minerals to sustain life in the trough. The heated locations have a temperature of about 700 degrees Fahrenheit.

Is deep sea water salty?

Deep ocean water has a very uniform temperature, around 0-3 °C, and a salinity of about 3.5% or, as oceanographers state, 35 ppt (parts per thousand).

How deep can a human survive in the ocean?

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. When free diving the body goes through several changes to help with acclimatisation.

Is the MEG still alive in 2021?

Megalodon is NOT alive today, it went extinct around 3.5 million years ago.

Is megalodon alive now?

The Creature That Killed Off The Giant Megalodon Might Still Live in Our Oceans Today. For twenty million years, the world's oceans were home to a monstrous shark, named the 'megalodon'. Then suddenly, without explanation, the 18-metre-long (50 foot) super predator disappeared.

What to do if a shark is circling you?

Sharks typically attempt to circle behind you to take a bite, so they will feel less comfortable if you keep an eye on them. Keep calm and slowly back away. If none of the above options are viable, you should fight back and focus your attacks on the shark's eyes and gills because of the areas' sensitivity.

Why did James Cameron go to Mariana Trench?

The first human to reach the 6.8-mile-deep (11-kilometer-deep) undersea valley solo, Cameron arrived at the bottom with the tech to collect scientific data, specimens, and visions unthinkable in 1960, when the only other manned Challenger Deep dive took place, according to members of the National Geographic expedition.

What is the scariest thing in the Mariana Trench?

1. Deep-Sea Dragonfish. Our first Mariana trench creature is the deep-sea predator, the dragonfish (Stomiidae).

What's the scariest fish in the Mariana Trench?

Featured as a scary creature in the film, the Black seadevil is just as terrifying in real life. Sharp teeth, gaping mouth and eyes exploding out of their sockets; this angler fish is known for its luminous antenna-like muscle protruding from its head. This light attracts its prey into close vicinity for an easy catch.

What is the deepest sea creature ever found?

Meet the deepest fish in the ocean, a new species named the Mariana snailfish by an international team of researchers that discovered it. The Mariana snailfish (Pseudoliparis swirei) thrives at depths of up to about 8,000 meters (26,200 feet) along the Mariana Trench near Guam.

Can a human survive in Mariana Trench?

You would never make it to the bottom of the ocean without any equipment, because you would run out of oxygen, and your body would be shut down by the pressure underwater. So if you want any chance of surviving this journey, you'll need some sort of capsule to bring you safely to the bottom.
