The
Mariana Trench is believed to be the deepest point in the world, and the lowest
point in Mariana Trench is known by the name –Challenger Deep. The gap between
the tectonic plates proliferates up to 1500 miles forming the Challenger Deep
point. But, the question is whether this is the deepest point or not? Is there
anything below the Mariana Trench? Let us dig in deeper and find out, what is
below the Mariana Trench’s deepest point.
To
find out what is below Mariana Trench an expedition was conducted in the year
1875, which covered around 70,000 miles long voyage all around the globe. The
team wanted to discover whether there was any other point that was more deep
that the Challenger Deep or not. Therefore, they set on a sail with some
weights tethered to 144 miles long ropes. The first depth that was reported was
around 26,850 feet deep. The results changed when a royal vessel named HMS
Challenger used sonar radiations to detect the depth of the point. The figure
was reportedly 35,761 feet deep. However, due to advanced sonar technique now
the actual measurement has come up to be around 36,070.
Scientists
continue to put efforts to find more deep points across the world; but, none
have surpassed the depth of the Mariana Trench, yet.
Life in the Trench:
Recently,
the scientists have discovered there are certain creatures that survive in the
harsh climatic conditions of Mariana Trench. With high pressure and darkness,
the creatures are still alive and healthy. The Mariana Trench faces a scarcity
of food, as the gorge is very far away from land. Therefore, reaching of the
leaves or even of the trees to the bottom of the Trench is not possible.
Sometimes, even the dead planktons are unable to reach that depth. Perhaps, the
creatures living in that depth rely on chemical substances mostly on sulfur or
methane. Also, some of the creatures feed on the lowest marine animals in the
food chain.
According
to the scientists, the creatures surviving in the Mariana Trench are mainly
amphipods, holothurians, and xenophyophores.
Pollution in the Trench:
Unfortunately,
as Mariana Trench is the deepest point it possesses greater risks of deposition
of chemical substance. According to the reports released in the latest study,
the chemical substances that were discarded by humans in the 1970s are found as
litter and pollutants in the deepest point on the Earth.
