Where Is the Deepest Place on Earth?

Where Is the Deepest Place on Earth?

With a measured depth of approximately 35,797 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.

The Challenger deep is named after a British Royal Navy ship called the HMS Challenger. The Challenger was the first ship to measure the depths of what is now known as the Challenger deep.

The trench was measured by “sounding,” which involves dropping a very long line with a weight at the end into a body of water. Improvements and advancements in technology have allowed modern scientists and researchers to use sonar to study ocean depths.

Only four descents into the Challenger deep have ever been achieved. The first was in 1960 by a vessel called the Trieste.

The second descent into the Challenger deep was made in 1995 by an unmanned deep-sea robotic probe named Kaiko.

The third descent into the Challenger deep took place in 2009, when the U.S. Navy sent the Nereus on an exploration.

The Nereus is a hybrid remotely-operated vehicle, also known as an HROV.

The most recent descent into the Challenger deep happened in 2012 by solo-diver James Cameron in the DEEPSEA CHALLENGER.
