Basic View Of Mariana Trench
The highest peak on the earth, Mount Everest is scaled by a large number of climbers auspiciously. But what about the deepest point of the earth, Mariana Trench. Only two people on this planet descended to the deepest point, the Challenger Deep in the Pacific Ocean’s Mariana Trench.
On average Mariana Trench is 43 miles (69 kilometers) wide and 1,500 miles (2,550 kilometers) long curve-shaped cicatrix in the Earth’s crust. It lies in between east of the Mariana Islands and western Pacific east of the Philippines.
If Mount Everest ever settled into the Mariana Trench then it will be one mile (1.6 kilometers) above it. All the deep trench and channels that slash through the ocean floor is a global network of Mariana Trench. The collision of two tectonic plates will lead to the formation of an ocean trench.
In 1875, deepness of Mariana Trench was first estimated of 4,475 fathoms (about five miles, or eight kilometers) with the help of H.M.S. Challenger. For measuring the depth, challenger’s scientist used a weighted sounding rope. H.M.S. Challenger was the British ship which is the part of the oceanographic cruise.
And in 1951 the deepness of Mariana Trench is again measured, but with the help of vessel H.M.S. Challenger II. This time the depth comes to be approximately 7 miles (11 kilometers).
In 2009, W.BUSH established Marianas Trench Marine National Monument as the Mariana Trench comes in U.S. protected zone. Basically, the monument is for research purpose for ease of scientist.
Due to the superlative depth of Marina Trench, its temperature always maintained above freezing point and surroundings submerged in darkness all the time. The pressure exerted on per square inch was about eight tons. This is much more as compared to the standard atmospheric pressure at sea level.
In entire human history, only two men explore the depth of Mariana Trench. In 1960, Jacques Piccard and Navy Lt. Don Walsh take dive into the Challenger deep and successfully come back.
This historic dive takes 5 hours of a long time, where the duo spent 20 minutes at the bottom. The condition was as blurring as they can’t take the snaps.
Before their historic dive, there was only one common question on the tongue of each scientist. Is life can be possible under such pressure?
When both of them exploring the depths, Trieste‘s floodlight cast upon an organism and Piccard thought was a flatfish.
However, Piccard explains elaborately this phase of journey in his book and said that
“Could life exist in the greatest depths of the ocean? It could!”
