Keep reading to find out where is the deepest place on Earth. With a measured depthof 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 shipto measure the depthsof 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 sonarto study ocean depths.
Only four descents into the Challenger deep have ever been achieved. The first was in 1960 by a vesselcalled 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. So now you know where is the deepest place on Earth.
How deep can a human dive before being crushed? The need to do decompression stops increases with depth. A diver at 6 metres (20 ft) may be able to dive for many hours without needing to do decompression stops. At depths greater than 40 metres (130 ft), a diver may have only a few minutes at the deepest part of the dive before decompression stops are needed.
