Who is the only person who has been to the bottom of the lowest point in the ocean?

On 23 January 1960, two explorers, US navy lieutenant Don Walsh and Swiss engineer Jacques Piccard, became the first people to dive 11km (seven miles) to the bottom of the Mariana Trench. As a new wave of adventurers gear up to repeat the epic journey, Don Walsh tells the BBC about their remarkable deep-sea feat.

Has anyone ever touched the bottom of the 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.

Can you fit Mt Everest in the Marianas Trench?

It is 11,034 meters (36,201 feet) deep, which is almost 7 miles. Tell students that if you placed Mount Everest at the bottom of the Mariana Trench, the peak would still be 2,133 meters (7,000 feet) below sea level.

Is there anywhere deeper than the Challenger Deep?

Originally Answered: Is there a place deeper than the Mariana Trench? Yes, but you can’t go there. It’s only 9 inches wide. It’s the Kola Superdeep Borehole, 12,262 meters deep, around 1300m deeper than the Challenger Deep in the Mariana Trench.

How long does it take to reach Challenger Deep?

Pre-expedition estimates put the Challenger Deep descent at about 90 minutes. (Animation: Cameron’s Mariana Trench dive compressed into one minute.) By contrast, some current remotely operated vehicles, or ROVs, descend at about 40 meters (130 feet) a minute, added Stern, who isn’t part of the expedition.

What’s at the bottom of Challenger Deep?

They found one 8,530 feet (2,600 m) below the surface, one 14,600 feet (4,450 m) and two at the deepest point they reached. At the deepest point, they were accompanied by some transparent bottom-dwelling sea cucumbers (Holothurians) and an amphipod called the Hirondellia gigas.

How cold is the water in Challenger Deep?

between 34 to 39 degrees Fahrenheit
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.

What’s at the bottom of the Challenger Deep?

How deep is Mount Everest in the Mariana Trench?

Tell students that if you placed Mount Everest at the bottom of the Mariana Trench, the peak would still be 2,133 meters (7,000 feet) below sea level. Show students NOAA’s Mariana Trench animation. Tell them that the animation reflects actual digital bathymetric data, which is measurement data of water depth. 2.

How deep is the Challenger Deep?

The Challenger Deep is 10,994 meters (36,070 feet) deep, and it is officially the deepest point on earth that can be reached without digging below the surface (if you want to read about the world’s deepest man-made hole check out this article).

How many people have reached the bottom of the Mariana Trench?

Until now, only two people have successfully made it to the bottom of Challenger Deep, the planet’s deepest point at the southern end of the Mariana Trench. Back in 1960, oceanographer Don Walsh was the first to make it down to the trench successfully, reaching about 35,814 feet (10,916 m).

What is the deepest trench in the world?

Wikimedia Commons The Mariana Trench is the deepest trench in the world and Challenger Deep is the deepest part of that trench. This area of the ocean floor more closely resembles something from a science fiction novel rather than any other landscape on Earth.
