Deepest Known Point in the Ocean
The ocean is a vast area of the Earth. It takes up almost 70 percent of the total area of the planet. Most of the areas underneath the ocean have never been discovered or are just waiting to be discovered by man. There are still many more parts of the ocean that man has never been to and probably never will without the help of technology. It has its fair share of secrets aside from sudden disappearances and hidden treasure but what makes it very interesting is how deep it can be. We all know that this body of water can go deep for several kilometers down but we often think what is going on down there? Are there life forms that are able to survive tremendous pressure without any form of light? Surely we all want to find out.
Deepest Known Point
The deepest part of the world’s ocean is the Mariana Trench or the Marianas Trench. It is situated near the Philippines at the western region of the Pacific Ocean. It has a maximum known depth of 10.9 km which is the Challenger Deep. The Challenger Deep is a small area that is shaped like a valley. The bottom of the Challenger Deep the water columns can exert a pressure of 1086 bars which is a thousand times higher than the normal pressure at sea level. This can instantly crush a person. The temperature at the bottom can reach up to 1C.
The name came from the Mariana Islands that were situated near the trench. It was in 1668 when the Spaniards established a colony there that they named the islands. Scientists then named the deepest known point in the ocean Marianas Trench in honor of the nearest land situated next to the trench.
The trench was first discovered in 1875 with the Challenger expedition. It had a record depth of 8.184 km or 4,475 fathoms deep. It was in 1877 when a map was published called Tiefenkarte des Grossen Ozeans by Petermann. By 1899, the USS Nero had a record of 5269 fathoms and surveyed the trench using echo sounding which had a much more precise record than the first one. By 1957, the Vityaz, a Soviet vessel record 36,201ft. But, it was on March 24, 1995 that the remotely operated vehicle called KAIKO that reached the deepest part of the Mariana Trench at 10,911 meters deep.
Within the years of 1997 and 2001, there was even a spot along the Marianas Trench that was found to be deeper than the Challenger Deep.
Life forms were also found in the Marianas Trench. Xenophyophores have been found along the trench. Researchers suggest that these microbial life forms thrive on the deep end. They are extremely adaptable to the harsh conditions in the deep ocean which helps make them thrive.
Truly a remarkable feat for the human race, we are still unable to decipher most of the areas within our own planet making things much more interesting for the humans to discover.
