Meta Description:
Investigate how scientists are now
making new findings at The Mariana Trench, the deepest trench in the world
where life exists more than 36,000 feet underwater.
A Journey to the Abyss
There is something significant that
lies underneath the surface of the Pacific Ocean: the Mariana Trench, which is
home to a large sub-aquatic canyon that is approximately 8,000 meters in
length. The Mariana Trench, which is located to the east of the Mariana Islands
in the western Pacific Ocean, is the deepest part of the ocean. It harbors the
most impressive and unusual species of agriculture and animals and is viewed by
scientists as the maximum depth of the ocean basin which reaches up to 1600 km
in the extensive area centering on more than two kilometers of folded origami
paper.
It is believed that over one million
animals are still undiscovered. The hunt for the species started in 1875 with
the HMS Challenger expedition. As of today, the boundaries of biological
research involving extreme deep sea benthos of the Mariana Trench are almost
complete. Most marine species reticulate at depths greater than 10,500 meters.
A few species can withstand barely above freezing temperatures. With time, those
species adapted and nucleated in these regions.
Life’s Extreme Survival in the Depths of Oceans
Life at these depths exists under
extraordinary conditions, which are beyond the reach of imagination. The
pressure at the bottom ranges from 2,200 kg/cm2. This is like having to bear
the weight of 50 large jumbo jets on the tops of one's head. In spite of total
absence of light and pleasantly low temperatures, life persists.
Water at these depths has more
dissolved oxygen in it than was anticipated by scientists. This discovery
helped in getting an understanding as to how would a diverse life inhabits such
regions. But as most of the dark lined creatures underwater don the ability to
see, it implies that organisms employ other senses for direction and combat.
The Bottom of the World
Living things at these depths of the
ocean are battling for survival under what seem like unfathomable conditions.
According to scientists, the pressure at the deepest, about 15,750 PSIs or
1,079 Atmospheres at sea level, can be equated to one having 50 jumbo jets
stacked on their head. Life becomes impossible at such depths and in such
temperatures – temperatures which are scarcely above freezing and complete
darkness exists.
At such depths, water quite
surprisingly has a greater quantity of dissolved oxygen than the researchers
had predicted. This particular finding assisted researchers in figuring out how
it’s possible for such a variety of marine creatures to exist even though the
circumstances are so intolerable. Unfortunately, the absence of light means
that many of these animals hunt using their other senses.
Extraordinary Life Forms Found Deep In The Ocean
Recent explorations have uncovered
upsetting and disturbing evidence of lifers with completely different
growth/developmental patterns from the norm. The Mariana snailfish, a
ghost-like fish, was found at a depth of about 26,900 feet and has special
proteins within its cells to prevent collapse. Another species of jellyfish
glows in the dark due to its inbuilt ability to produce light.
Amphipod ‘scavengers’, as long as
twelve inches, are capable of breaking organic material that sinks from above.
Such saucer-eyed gullets are very important for the ecology of the deep sea.
Whilst, hadal snailfish, which are semi-transparent, hasten through the seas
due to their evolutionary features.
Scientific Exploration Challenges in Mariana Trench
Winterse Implementation: Excavating
the Trench allows the investigation of new, hi-tech tools, who are very few in
the world today. Very few specialized submersibles can bear that much pressure
at such depths. However, modern vessels like the DSV Alvin and Triton 36000/2
achieve astonishing feat of diving to such depths through their engineering and
material construction.
Every single dive should be planned
and executed in a perfect manner. Changes in temperature and pressure
differences are always threats to equipment as well as the crew. However, the
innovations go on and the issues related to the deep sea remain unsolved
because of scientists’ perseverance.
Environmental Concerns and Conservation
Nonetheless, there has been evidence
linking anthropogenic impacts even at those depths which has been worrying.
Most of the researchers found microplastics within the samples which were
collected from the deepest trench. Further, there are some chemical pollutants
that are bio-accumulated in deep sea organisms that threaten other parts of
this ecosystem as well.
As a result, global efforts have been
put to protect this beauty from further damage. The Marianas Trench Marine National
Monument, which was established in 2009, aims specifically at conserving that
area. Given that the entire area is for planned destruction, the scientists are
actively monitoring its dynamics and develop environmentally sound methods of
conducting oceanographic research.
Conclusion
One of the most mysterious sites on
the planet is the Mariana Trench. Beneath its shear walls are surprises of
entirely new living organisms and astonishing geological features that have not
yet been defined by scientists. As time goes by, such more secrets of this
marvelous world under the water are going to be explored.
Ocean science is interested in understanding and protecting
the Mariana Trench.
The trench does not only allow
comprehending how the structure of the Earth is functioning, this riddle also
draws attention on the breath taking adaptability of life. It is an outstanding
natural beauty which deserves to be preserved for the grandchildren, great
grandchildren and great great grandchildren.
FAQs
Q1: How deep is the Mariana Trench?
The maximum depth of the trench is around 36,070 feet,
approximately the size of the Challenger Deep submarine which is the world’s
deepest known oceanic point. Even
if Mount Everest were at the bottom, above sea level, its summit would be a
mile below the water's surface.
Q2: What kind of creatures inhabit
the Mariana Trench?
The Mariana Trench is so enormous
that other unique species also inhabit the trench including:
• Marianas snailfish
• Dumbo octopuses
• Hadal amphipods
• Bioluminescent jellyfish
• Deep-sea anglerfish
• Different types of sea cucumbers.
Q3: Why can't common submarines go
far in the Mariana Trench?
Normal submarines would not withstand
those depths because of the excessive pressure. It is only the specific vessels
that support reinforced hulls, and pressure resistant materials that can reach
these depths.
Q4: Has anybody set foot at the
bottom of the Mariana Trench?
Yes. The Trieste was the first manned
craft to descend into the bottom of the ocean in 1960 with two men onboard
Jacques Piccard and Don Walsh. In 2012, James Cameron descended into the deep
sea in the Deepsea Challenger.
Q5: Where on the map can we find the
Mariana Trench?
The trench is located Near the
Mariana Islands, in the western Pacific Ocean, around 200 km towards the
eastern direction in Guatemala region.
Q6: Is it true that the Mariana
Trench has light at its floor?
It is not possible for natural
sunshine to penetrate these depths. The only source of illumination is research
vessels and bioluminescent organisms.
Q7: How does pollution impact the Mariana Trench?
As sad as it is, the deepest parts of this trench have been
studied and as a result ; microplastics and pollutants of chemical origin are
found. These pollutants can be a threat to the one of a kind ecosystem and its
residents.
Q8: What is the temperature of water in Mariana Trench?
The temperature of water at the bottom of the trench is
approximately 34-39 ° F or 1-4 °C.
Q9: Does the Mariana Trench have any volcanic activity?
Indeed, this trench is located in the so called Ring of Fire
and has active underwater volcanoes and hydrothermal vents.
Q10: How did this trench come about?
The trench was created through a process named subduction,
where the Pacific tectonic plate is pushed under the Philippine plate to form
the oceanic trench.
