Is the Challenger Deep in the Mariana Trench?
While thousands of climbers have successfully scaled Mount Everest, the highest point on Earth, only two people have descended to the planet’s deepest point, the Challenger Deep in the Pacific Ocean’s Mariana Trench.
What was found at the bottom of Challenger Deep?
Discoveries in the Challenge Deep included “vibrantly colorful” rocky outcrops that could be chemical deposits, prawn-like supergiant amphopods, and bottom-dwelling Holothurians, or sea cucumbers.
How much deeper is challenger than Mariana Trench?
After all, it was only in 1997 that researchers discovered the Sirena Deep, which is also located in the Mariana Trench, which they measured at 35,210 feet, less than a thousand feet shallower than the Challenger Deep.
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 is inside 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 lives in the 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.
Where is the DEEPSEA CHALLENGER now?
The Mariana Trench in the Pacific Ocean is the deepest part of the world’s oceans. The deepest point in this trench, known as Challenger Deep, lies some 11,000 metres (nearly 7 miles) below the surface, and about 320 kilometres (about 200 miles) south-west of the nearest inhabited territory, the island of Guam.
Do animals live in the Challenger Deep?
How long can the Deepsea Challenger stay underwater?

Unlike the Trieste, which spent only 20 minutes on the ocean floor and had no research or camera equipment, the DEEPSEA CHALLENGER was designed as a science platform and was able to remain at the bottom of the Mariana Trench for three hours to explore, take samples and capture the first-ever high-resolution images of …

What is the deepest point in the Mariana Trench?
The deepest point in the Mariana Trench and in the oceans is Challenger Deep which is three hundred and forty kilometers off the coast of Guam.

How deep can a submarine go into the Marianna Trench?
Trieste is a Swiss-designed, Italian-built deep-diving research bathyscaphe which reached a record depth of about 10,911 metres (35,797 ft) in the Challenger Deep of the Mariana Trench near Guam in the Pacific.
Why is the Challenger Deep so deep?
We present the geological characteristics of the region, including seismic evidence for a tear in the subducting plate that has influenced the deformation of the overriding plate. The rollback caused by this tear creates greater depths along the southern part of the trench than elsewhere along its length.
