Out of all the trenches in the world, the Mariana Trench is the deepest. Located in the western Pacific east of the Philippines is where these complex systems of trenches were discovered. During the year 1875, the submersible named the Challenger Deep came across the trench. After that, many scientists became very obsessed with the idea of finding out everything about it. Upon discovery, everyone thought the trench had nothing in it; they assumed it was lifeless. These assumptions made many scientists want to go down in the trench and see for themselves if the rumors were true. The first thought was to have highly trained divers go down into the trench, but that idea was later cut out of the picture when the pressure of the trench was taken into consideration. Since the system of trenches are so deep down, approximately 10,994 meters below the sea’s surface, the pressure is immense. If a human were to go down into the trench, their blood circulation would be cut off and their skull would be crushed along with every other bone and organ in their body.

After the curiosity became too much to handle, scientists later launched a submersible named Bathyscaphe Trieste on August 26, 1953. This submersible carried two people, Jacques Piccard and Don Walsh, both certified oceanographers. After sent down into the depths and darkness of the trenches they soon discovered that there was indeed life down there. Hitting the bottom of the trench’s floor, a small fish swam across the Bathyscaphe, indicating signs of life. This discovery excited many scientists across the world because they discovered something that was able to withstand the pressure and temperature of an area that deep. Later on, many other species of marine life were found in the trench’s systems, such as many types of eels, sea slugs, and deep-sea sharks.
