Has anyone gone to the bottom of the Mariana Trench?

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.

How deep has a human gone in the ocean?

The submersible’s passengers faced the nightmarish prospect of the cable breaking and the bathysphere plunging to the depths to be crushed under pressure. Bathyscaphe: Developed by Swiss physicist Auguste Piccard, it could withstand the pressure at 4,600 feet.

Is there anything deeper than Challenger Deep?

The Mariana Trench is a crescent-shaped trench in the Western Pacific, just east of the Mariana Islands near Guam. The ocean’s second-deepest place is also in the Mariana Trench. The Sirena Deep, which lies 124 miles (200 kilometers) to the east of Challenger Deep, is a bruising 35,462 feet deep (10,809 m).

Is Challenger Deep really the deepest point on Earth?

The Challenger Deep is the lowest point in the Mariana Trench, a gap between tectonic plates that stretches 1,500 miles along the western Pacific, and is thought to be the deepest chasm in all the world’s oceans. At the bottom the pressure reaches over 15,000 pounds per square inch.

Is Megalodon in the Mariana Trench?

According to website Exemplore: “While it may be true that Megalodon lives in the upper part of the water column over the Mariana Trench, it probably has no reason to hide in its depths. However, scientists have dismissed this idea and state that it is extremely unlikely that the megalodon still lives.

How much of the earth is still unexplored?

The extent of human impact on these underwater ecosystems is impressive. Still, we’ve only mapped 5 percent of the world’s seafloor in any detail. Excluding dry land, that leaves about 65 percent of the Earth unexplored.

What’s at the bottom of Mariana Trench?

Toward the southern end of the Mariana Trench lies the Challenger Deep. It sits 36,070 feet below sea level, making it the point most distant from the water’s surface and the deepest part of the Trench. Don Walsh reached the Challenger Deep in a U.S. Navy submersible.

Is there anything deeper than Mariana Trench?

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.

What is the deepest and hottest layer of Earth?

The core is the deepest and hottest layer and is mostly composed of metals, and it is beneath the Earth’s mantle. The outer core is the first layer of the core, and it extends to a depth of approximately 2,890 kilometers below the Earth’s crust and measures 2,300 kilometers thick.

How was the Mariana Trench became Earth’s deepest point?

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. When it’s fresh, lava is comparatively warm and buoyant, riding high on the underlying mantle.

What is the deepest place in earths crust?

Welcome to The Deepest Place on Earth. Lying below a small, nondescript rusty cap in Murmansk, Russia, is the deepest hole ever drilled, reaching a whopping 12 kilometres (7.5 miles) into the Earth’s crust.

What is the deepest place on land?

With a measured depth of approximately 36,000 feet below sea level, a journey to the bottom of the Challenger Deep is nearly seven miles, making it the deepest known place on Earth.
