Was there a person in the Mariana Trench? Secrets of the Mariana Trench

They never cease to amaze us with their mysteries. The described place has also not yet been properly studied for completely objective reasons.

So, we offer you interesting facts about the Mariana Trench or, as it is also called, the Mariana Trench. Below are valuable photographs of the mysterious inhabitants of this abyss.

It is located in the western part of the Pacific Ocean. This is the deepest place in the world known to date.

Having a V-shape, the depression runs along the Mariana Islands for 1,500 km.

Mariana Trench on the map

An interesting fact is that the Mariana Trench is located at the junction of the Pacific and Philippine.

The pressure at the bottom of the trench reaches 108.6 MPa, which is almost 1072 times higher than normal pressure.

You probably now understand that due to such conditions, exploring the mysterious bottom of the world, as this place is also called, is extremely difficult. However, the scientific community, since the end of the 19th century, has not stopped studying this mystery of nature step by step.

Mariana Trench Research

In 1875, the first attempt was made to explore the Mariana Trench globally. The British expedition "Challenger" carried out measurements and analysis of the trench. It was this group of scientists who set the initial mark at 8184 meters.

Of course, this was not the full depth, since the capabilities of that time were significantly more modest than today's measuring systems.

Soviet scientists also made enormous contributions to research. An expedition led by the research vessel Vityaz began its own studies in 1957 and discovered that there was life at a depth of more than 7,000 meters.

Until this time, there was a strong belief that life at such depths was simply impossible.

We invite you to look at an interesting scale image of the Mariana Trench:

Diving to the bottom of the Mariana Trench

1960 was one of the most fruitful years in terms of research into the Mariana Trench. The research bathyscaphe Trieste made a record dive to a depth of 10,915 meters.

This is where something mysterious and inexplicable began. Special devices that record underwater sound began to transmit eerie noises to the surface, reminiscent of the grinding of a saw on metal.

The monitors registered mystical shadows that were shaped like fairy-tale dragons with several heads. For an hour, scientists tried to record as much data as possible, but then the situation began to get out of control.

It was decided to immediately raise the bathyscaphe to the surface, as there were reasonable fears that if we waited a little longer, the bathyscaphe would forever remain in the mysterious abyss of the Mariana Trench.

For more than 8 hours, specialists recovered from the bottom unique equipment made of heavy-duty materials.

Of course, all the instruments, and the bathyscaphe itself, were carefully placed on a special platform to study the surface.

Imagine the surprise of the scientists when it turned out that almost all the elements of the unique apparatus, made of the strongest metals at that time, were severely deformed and distorted.

The cable, 20 cm in diameter, lowering the bathyscaphe to the bottom of the Mariana Trench was half sawn through. Who tried to cut it and why remains a mystery to this day.

An interesting fact is that only in 1996 the American newspaper The New York Times published details of this unique study.

Lizard from the Mariana Trench

The German Haifish expedition also encountered the inexplicable mysteries of the Mariana Trench. While plunging the research apparatus to the bottom, the scientists faced unexpected difficulties.

Being at a depth of 7 kilometers under water, they decided to lift the equipment.

But the technology refused to obey. Then special infrared cameras were turned on to find out the cause of the failures. However, what they saw on the monitors plunged them into indescribable horror.

A fantastic giant-sized lizard was clearly visible on the screen, which was trying to chew the bathyscaphe like a squirrel nut.

Being in a state of shock, the hydronauts activated the so-called electric gun. Having received a powerful electric shock, the lizard disappeared into the abyss.

What it was, the fantasy of scientists obsessed with research, mass hypnosis, the delirium of people tired of colossal stress, or just someone’s joke is still unknown.

The deepest place in the Mariana Trench

On December 7, 2011, researchers at the University of New Hampshire sank a unique robot to the bottom of the trench under study.

Thanks to modern equipment, it was possible to record a depth of 10,994 m (+/- 40 m). This place was named after the first expedition (1875), about which we wrote above: “ Challenger Deep».

Inhabitants of the Mariana Trench

Of course, after these inexplicable and even mystical secrets, natural questions began to arise: what monsters live at the bottom of the Mariana Trench? After all, for a long time it was believed that below 6000 meters the existence of living beings is in principle impossible.

However, later studies of the Pacific Ocean in general, and the Mariana Trench in particular, confirmed the fact that at a much greater depth, in impenetrable darkness, under monstrous pressure and water temperatures close to 0 degrees, a huge number of unprecedented creatures live.

Undoubtedly, without modern technology, made of the most durable materials and equipped with cameras unique in their properties, such research would simply be impossible.

Half-meter mutant octopus

One and a half meter monster

As a general summary, we can confidently say that at the bottom of the Mariana Trench, between 6000 and 11000 meters under water, the following were reliably discovered: worms (up to 1.5 meters in size), crayfish, a variety of amphipods, gastropods, mutant octopuses, mysterious, not identified soft-bodied creatures of two meters in size, etc.

These inhabitants feed mainly on bacteria and the so-called “corpse rain,” that is, dead organisms that slowly sink to the bottom.

Hardly anyone doubts that the Mariana Trench stores many more. However, people do not give up trying to explore this unique place on the planet.

Thus, the only people who dared to dive to the “bottom of the earth” were the American marine specialist Don Walsh and the Swiss scientist Jacques Picard. On the same bathyscaphe "Trieste" they reached the bottom on January 23, 1960, descending to a depth of 10915 meters.

However, on March 26, 2012, James Cameron, an American director, made a solo dive to the bottom of the deepest point of the World Ocean. The bathyscaphe collected all the necessary samples and took valuable photos and videos. Thus, we now know that only three people visited the Challenger Deep.

Did they manage to answer at least half of the questions? Of course not, since the Mariana Trench still hides much more mysterious and inexplicable things.

By the way, James Cameron stated that after diving to the bottom he felt completely cut off from the human world. Moreover, he assured that no monsters simply exist at the bottom of the Mariana Trench.

But here we can recall the primitive Soviet statement, after a flight into space: “Gagarin flew into space - he did not see God.” From this the conclusion was drawn that there is no God.

Likewise here, we cannot say unequivocally that the giant lizard and other creatures that scientists saw during previous research were the result of someone’s sick imagination.

It is important to understand that the geographical object under study has a length of more than 1000 kilometers. Therefore, potential monsters, inhabitants of the Mariana Trench, could well be located many hundreds of kilometers from the research site.

However, these are just hypotheses.

Panorama of the Mariana Trench on Yandex Map

Another interesting fact may intrigue you. On April 1, 2012, the Yandex company published a comic panorama of the Mariana Trench. On it you can see a sunken ship, water drains and even the glowing eyes of a mysterious underwater monster.

Despite the humorous idea, this panorama is tied to a real place and is still available to users.

The Abyss knows how to keep its secrets, and our civilization has not yet reached such a development as to “hack” natural mysteries. However, who knows, maybe one of the readers of this article in the future will become the genius who will be able to solve this problem?

Excellent students at school firmly learned: the highest point on earth is Mount Everest (8848 m), the deepest depression is Mariana. However, if we know a lot of interesting facts about Everest, then most people know nothing about the trench in the Pacific Ocean, in addition to the fact that it is the deepest.

FIVE HOURS DOWN, THREE HOURS UP

Despite the fact that the oceans are closer to us than the mountain peaks and even more so the distant planets of the solar system, people have explored only five percent of the seabed, which still remains one of the greatest mysteries of our planet.

With an average width of 69 km, the Mariana Trench was formed several million years ago due to shifts of tectonic plates and stretches in the shape of a crescent for two and a half thousand kilometers along the Mariana Islands.

Its depth, according to recent research, is 10,994 meters ± 40 meters (for comparison: the equatorial diameter of the Earth is 12,756 km), the water pressure at the bottom reaches 108.6 MPa - this is more than 1100 times more than normal atmospheric pressure!

The Mariana Trench, also called the Earth's fourth pole, was discovered in 1872 by the crew of the British research vessel Challenger. The crew took measurements of the bottom at various points in the Pacific Ocean.

Another measurement was made in the area of ​​​​the Mariana Islands, but the kilometer-long rope was not enough, and then the captain ordered two more kilometer sections to be added to it. Then again and again...

Almost a hundred years later, the echo sounder of another English, but under the same name, scientific vessel recorded a depth of 10,863 meters in the Mariana Trench area. After this, the deepest point of the ocean floor began to be called the “Challenger Deep”.

In 1957, Soviet researchers established the presence of life at depths of more than 7,000 meters, thereby refuting the prevailing opinion at that time about the impossibility of life at depths of more than 6,000-7,000 meters, and also clarified the British data, recording a depth of 11,023 meters in the Mariana Trench .

The first human dive to the bottom of the depression took place in 1960. It was carried out on the Trieste bathyscaphe by the American Don Walsh and the Swiss oceanographer Jacques Picard.

The descent into the abyss took them almost five hours, and the ascent took about three hours; the researchers spent only 20 minutes at the bottom. But even this time was enough for them to make a sensational discovery - in the bottom waters they discovered flat fish up to 30 cm in size, similar to flounder, unknown to science.

LIFE IN utter darkness

In the course of further research using unmanned deep-sea vehicles, it turned out that at the bottom of the depression, despite the terrifying water pressure, a wide variety of species of living organisms live. Giant 10-centimeter amoebas - xenophyophores, which under normal terrestrial conditions can only be seen with a microscope, amazing two-meter worms, no less huge starfish, mutant octopuses and, naturally, fish.

The latter amaze with their terrifying appearance. Their distinctive feature is a huge mouth and many teeth. Many spread their jaws so wide that even a small predator can swallow whole an animal larger than itself.

There are also quite unusual creatures, reaching two meters in size with a soft jelly-like body, which have no analogues in nature.

It would seem that at such a depth the temperature should be at Antarctic levels. However, Challenger Deep contains hydrothermal vents called “black smokers.” They constantly heat the water and thereby maintain the overall temperature in the depression at 1-4 degrees Celsius.

The inhabitants of the Mariana Trench live in pitch darkness, some of them are blind, others have huge telescopic eyes that catch the slightest glare of light. Some individuals have “lanterns” on their heads that emit different colors.

There are fish in whose bodies a luminous liquid accumulates. When they sense danger, they splash this liquid towards the enemy and hide behind this “curtain of light.” The appearance of such animals is very unusual for our perception and can cause disgust and even inspire a feeling of fear.

But it is obvious that not all the mysteries of the Mariana Trench have yet been solved. Some strange animals of truly incredible size live in the depths!

THE LIZARD TRIED TO CHEAT THE BATHYSCAPH LIKE A NUT

Sometimes on the shore, not far from the Mariana Trench, people find the bodies of dead 40-meter monsters. Giant teeth were also discovered in those places. Scientists have proven that they belong to a multi-ton prehistoric megalodon shark, the span of which reached two meters.

These sharks were thought to have gone extinct about three million years ago, but the teeth found are much younger. So have the ancient monsters really disappeared?

In 2003, another sensational results of research into the Mariana Trench were published in the United States. Scientists have submerged an unmanned platform equipped with searchlights, sensitive video systems and microphones in the deepest part of the world's oceans.

The platform was lowered on 6 inch-section steel cables. At first, the technology did not provide any unusual information. But a few hours after the dive, the silhouettes of strange large objects (at least 12-16 meters) began to flash on the monitor screens in the light of powerful spotlights, and at that time the microphones transmitted sharp sounds to the recording devices - the grinding of iron and dull, uniform blows on metal.

When the platform was raised (without being lowered to the bottom due to incomprehensible obstacles that prevented the descent), it was discovered that the powerful steel structures were bent, and the steel cables seemed to have been sawed off. A little more - and the platform would forever remain the Challenger Deep.

Previously, something similar happened to the German device “Hayfish”. Having descended to a depth of 7 kilometers, he suddenly refused to emerge. To find out what was wrong, the researchers turned on an infrared camera.

What they saw in the next few seconds seemed to them a collective hallucination: a huge prehistoric lizard, clinging to the bathyscaphe with its teeth, tried to chew it like a nut.

Having recovered from the shock, the scientists activated the so-called electric gun, and the monster, struck by a powerful discharge, hastened to retreat.

Giant 10-centimeter amoeba - xenophyophora

WHO IS THE REAL “OWNER” OF PLANET EARTH

But it's not just fantastic monsters that are captured by deep-sea cameras. In the summer of 2012, the unmanned deep-sea vehicle Titan, launched from the research vessel Rick Mesenger, was in the Mariana Trench at a depth of 10,000 meters. His main goal was to film and photograph various underwater objects.

Suddenly the cameras recorded a strange multiple shine of a material very similar to metal. And then, several tens of meters from the device, several large objects appeared in the light of the spotlight.

Having approached these objects to the maximum allowable distance, the Titan displayed a very unusual picture on the monitors of the scientists on the Rick Mesenger. On an area of ​​approximately a square kilometer there were about 50 large cylindrical objects, very similar to... flying saucers!

A few minutes after the “UFO airfield” was recorded, the Titan stopped communicating and never surfaced.

There are a lot of well-known facts that, if they do not confirm the possibility of the existence of intelligent creatures in the depths of the sea, then, in any case, fully explain why modern science still knows nothing about them.

Firstly, man's native habitat - the earth's surface - occupies only a little more than a quarter of the land surface. So our planet could well be called the Ocean planet rather than the Earth.

Secondly, as everyone knows, life originated in water, so marine intelligence (if it exists) is about one and a half million years older than humans.

That is why, according to some experts, at the bottom of the Mariana Trench, thanks to the presence of active hydrothermal springs, not only entire colonies of prehistoric animals that have survived to this day can exist, but also an underwater civilization of intelligent creatures unknown to earthlings! The “fourth pole” of the Earth, in the opinion of scientists, is the most suitable place for them to live.

And once again the question arises: is man the only “master” of planet Earth?

FIELD RESEARCH IS PLANNED FOR SUMMER 2015

The third person in the entire history of exploration of the Mariana Trench to descend to its bottom was exactly three years ago. James Cameron.

“Almost everything on the earth’s land has been explored,” he explained his decision. — In space, bosses prefer to send people circling around the Earth, and send machine guns to other planets. For the joys of discovering the unknown, there is only one field of activity left - the ocean. Only about 3% of its water volume has been studied, and what’s next is unknown.”

On the DeepSes Challenge bathyscaphe, being in a half-bent state, since the internal diameter of the device did not exceed 109 cm, the famous film director observed everything that was happening in this place until mechanical problems forced him to rise from the surface.

Cameron managed to take samples of rocks and living organisms from the bottom, as well as film with 3D cameras. Subsequently, these shots formed the basis of a documentary film.

However, he never saw any of the terrible sea monsters. According to him, the very bottom of the ocean was “lunar... empty... lonely,” and he felt “complete isolation from all humanity.”

Meanwhile, in the telecommunications laboratory of Tomsk Polytechnic University, together with the Institute of Marine Technology Problems of the Far Eastern Branch of the Russian Academy of Sciences, the development of a domestic device for deep-sea research, which can descend to a depth of 12 kilometers, is in full swing.

Specialists working on the bathyscaphe declare that there are no analogues to the equipment they are developing in the world, and “field” studies of the sample in the waters of the Pacific Ocean are planned for the summer of 2015.

The famous traveler Fyodor Konyukhov also began working on the project “Diving into the Mariana Trench in a Bathyscaphe.” According to him, his goal is not just to touch the bottom of the deepest depression of the World Ocean, but also to spend two whole days there, conducting unique research.

The bathyscaphe is designed to accommodate two people and will be designed and built by an Australian company.

There are many amazing places in this world that have not yet been explored by man. It turns out that only 5% of the ocean area is subject to science, the rest remains a mystery to it, shrouded in darkness. One of these mysterious places is the Mariana Trench, the depth of which is the greatest among all the explored areas of the seabed. Mariana Trench is another name for the place.

Under the thickness of sea water, the pressure is a thousand times higher than the pressure that is recorded in normal sea space. But high-tech devices and caring risk-takers helped us learn at least a little about the deep crevasse. The Pacific Ocean is a true nature reserve, not only home to exotic, unique animals, but also to remarkable topographical features.

Everyone knows about the existence of this amazing object. Information about it is given to us from a young age, but over time we forget both the numbers and interesting facts about this strange and enchanting place. We decided to remind you where the Mariana Trench is and what it is. You can learn a lot about the ocean surface object.

The heroine of our article is named after the islands that are located near the “bottom of the earth”. It is located along the islands. In the Mariana Trench, the depth of which, it would seem, is capable of destroying all life, some microorganisms live that have mutated due to high pressure. This tectonic fault has steep slopes - about 8⁰. Below is a wide area about 5 km, which is divided by stone thresholds. The pressure at the very bottom is 108.6 MPa - more than anywhere else on planet Earth.

History of the study of the phenomenon

1872 is considered the date of discovery of the Mariana Trench; photographs of the object appear a little later. The tectonic fault was explored as best as possible by the British on a military corvette in 1951. The depth of the Mariana Trench becomes known - 10863 meters. Since it was the Challenger ship that sank to the very bottom, to the deepest point, it began to be called the “Challenger Abyss.”

Soviet scientists are joining the study. Since 1957, the scientific vessel Vityaz begins to plow the ocean and discovers that the depth of the Mariana Trench is even greater than previously stated - more than 11 kilometers. Our marine researchers established the fact of life at great depths, destroying the scientific stereotypes of that time. Subsequently, the ship was written off as a museum value. Experiments continue to this day. Five years ago, the “bottom of the world” was visited by the Nereus automatic apparatus, which dropped 11 km below ocean level, and took new photos and videos.

The dive to the “bottom of the Earth” takes at least five hours. The ascent is somewhat faster. You cannot stay at the very bottom for more than 12 minutes, taking into account the technology that was at the disposal of the researchers of that time. Cosmic sums have to be allocated for the study of such terrestrial objects, so work is proceeding slowly.

Where is it

The Mariana Trench is located on the western Pacific Ocean, two hundred meters from the islands of the same name. It looks like a crescent-shaped chasm, its length is more than 2550 km, and its width reaches almost 70 km.

The results of the study showed that the depth in the Mariana Trench is about 11 thousand meters. Everest reaches only 8840 m. If you need a comparison, the highest mountain on Earth can be turned upside down and placed entirely at the bottom of the Mariana Trench, but there will still be more than 2 km of water above the top. We are talking only about height; the width of the depression and the mountain do not coincide.

Interesting facts and stories

• It's hot there. It turns out it’s not cold at this crazy depth. The thermometer column shows a positive value - up to 4⁰С. There are hot springs in the gorge, they make the water a hundred points hotter. High pressure prevents the water column from boiling.

• Population. Ignoring the unsuitable conditions for life, the inhabitants of the “bottom of the world” settled down well. Huge xenophyophore amoebas live there - up to 10 cm. These are protozoa, but they have mutated due to hot water and pressure. Amoebas are able to survive in an environment filled with dangerous chemical elements.

• Mollusks also became inhabitants of the Mariana Trench, although the form of the cover should have simply cracked under great pressure. But the hot springs contain serpentine, rich in hydrogen and methane. It is these substances that allow mollusks to survive. They were able to adapt even to hydrogen sulfide emissions, converting them into protein compounds.

• The origin of life on the planet. Champagne Key on the ocean floor is a unique area underwater that contains liquid CO2. It forms specific bubbles, similar to those found in a glass of sparkling wine. Scientists have suggested that a primary form of life could have appeared around this key at one time. This is due to the presence of all necessary substances.

• The depression is slimy. There's no sand or anything like that. At the very bottom there is a layer of small shells and dead plankton accumulated over thousands of years. The pressure makes this mass look like mucus.

• Sulfur in a liquid aggregate state. The Mariana Trench, which is not so easy to photograph, is rich in various geoformations. At a depth of more than 400 meters, there is a whole volcano on the way to it. Near Daikoku there is a large lake filled with liquid sulfur, which cannot be found anywhere else on Earth. The substance boils at a temperature of 187⁰C, and underneath it is believed to be an even larger layer of liquid sulfur, which could also contribute to the formation of life on our planet.

• There are bridges there. In 2011, a group of research scientists discovered stone bridges in the Mariana Trench. Four structures stretch between the abyss for almost 70 km. They are located between two tectonic plates - the Pacific and the Philippine. One of them was discovered even earlier, in the 80s of the 20th century. It is very high, more than 2.5 km.

• The first person at such depth. Only three people have had the courage to dive into the Mariana Trench since its discovery in 1875. The first was an American, Lieutenant Don Walsh, and with him the scientist Jacques Piccard in 1960. The dive took place on the Challenger. In 2012, film director James Cameron visited the Mariana Trench in a submersible, and took a photo of it as a souvenir. The man was left with a painful impression of complete loneliness from this place

.

• The mystery of sawn cables. The incredible depths are terrifying. And the first explorers were afraid of unprecedented monsters inside the Mariana Trench. The first fact of collision with the unknown happened at the moment of the Glomar Challenger dive. The recorder began to record a metallic sound, like a grinding sound, and shadows appearing around the ship. The scientists became concerned about the expensive titanium equipment in the shape of a hedgehog, and the decision was made to lift the research vessel onto the ship. After extraction, the “hedgehog” turned out to be damaged, the 20-centimeter titanium cables were bent, or rather, half sawed through. There was a complete impression that someone wanted to stop the ship at depth.

• Prehistoric lizard. There was a hitch during the dive of the Highfish vessel with scientists on board. The device reached a depth of 7 kilometers and stopped. The researchers turned on the infrared camera. She suddenly snatched out of the ocean darkness a huge dinosaur that was biting into the submersible. They managed to drive him away with the help of an electric gun.

• The inhabitants of the Mariana Trench are protected by law. This is an American national monument, rightfully the largest nature reserve in the world. There are several restrictions on staying in this area. Mining is prohibited here, you can't fish, but you can swim.

The Mayan depression is inhabited by:

1. Scary and not so scary fish

2. Various octopuses

3. And other strange creatures

We are close to the fact that the Mariana Trench will soon become closer to modern humans. Perhaps in the near future there will even be tourism there. But for now, this option remains on par with the possibility of affordable space tourism. It is amazing how similar an terrestrial object is to distant stars in this respect. It is just as unexplored as the celestial bodies. But at least we know for sure that life exists in the Mariana Trench. According to a common hypothesis, it could have come from there. In this case, the study of the deepest place of the World Ocean acquires global significance.

Now anyone can watch the fantastic underwater world of the Mariana Trench, the deepest place on our planet, captured on video, or even enjoy a live video broadcast from an 11-kilometer depth. But until relatively recently, the Mariana Trench was considered the most unexplored point on the map of the Earth.

Sensational discovery by the Challenger team

We also know from the school curriculum that the highest point on the earth’s surface is the top of Mount Everest (8848 m), but the lowest is hidden under the waters of the Pacific Ocean and is located at the bottom of the Mariana Trench (10,994 m). We know quite a lot about Everest; climbers have conquered its peak more than once; there are enough photographs of this mountain taken both from the ground and from space. If Everest is all in plain sight and does not pose any mystery to scientists, then the depths of the Mariana Trench keep many secrets, because so far only three daredevils have managed to reach its bottom.

The Mariana Trench is located in the western part of the Pacific Ocean; it got its name from the Mariana Islands, which are located next to it. A place on the seabed that is unique in depth has received the status of a national monument; fishing and mining are prohibited here; in fact, it is a huge marine reserve. The shape of the depression is similar to a huge crescent, reaching 2550 km in length and 69 km in width. The bottom of the depression has a width of 1 to 5 km. The deepest point of the depression (10,994 m below sea level) was named “Challenger Deep” in honor of the British ship of the same name.

The honor of discovering the Mariana Trench belongs to the team of the British research vessel Challenger, which in 1872 carried out depth measurements at a number of points in the Pacific Ocean. When the ship was in the area, during the next depth measurement a hitch arose: the kilometer-long rope all went overboard, but it was not possible to reach the bottom. At the captain’s direction, a couple more kilometer sections were added to the rope, but, to everyone’s surprise, they were not enough and had to be added again and again. Then it was possible to establish a depth of 8367 meters, which, as it became known later, was significantly different from the real one. However, the underestimated value was quite enough to understand: the deepest place has been discovered in the World Ocean.

It is amazing that already in the 20th century, in 1951, it was the British who, using a deep-sea echo sounder, clarified the data of their compatriots; this time the maximum depth of the depression was more significant - 10,863 meters.

Six years later, Soviet scientists began studying the Mariana Trench, arriving in this area of ​​the Pacific Ocean on the research vessel Vityaz. Using special equipment, they recorded the maximum depth of the depression at 11,022 meters, and most importantly, they were able to establish the presence of life at a depth of about 7,000 meters. It is worth noting that in the scientific world at that time there was an opinion that due to the monstrous pressure and lack of light at such depths, there were no manifestations of life.

Dive into the world of silence and darkness

In 1960, people visited the bottom of the depression for the first time. How difficult and dangerous such a dive was can be judged by the colossal water pressure, which at the lowest point of the depression is 1072 times higher than the average atmospheric pressure. The dive to the bottom of the depression using the Trieste bathyscaphe was carried out by US Navy Lieutenant Don Walsh and researcher Jacques Picard. Bathyscaphe "Trieste" with walls 13 cm thick was created in the Italian city of the same name and was a rather massive structure.

They lowered the submersible to the bottom for five long hours; Despite such a long descent, the researchers spent only 20 minutes at the bottom at a depth of 10,911 meters; it took them about 3 hours to rise. Within minutes of being in the abyss, Walsh and Picard were able to make a very impressive discovery: they saw two 30-centimeter flat fish, similar to flounder, that swam past their porthole. Their presence at such a depth became a real scientific sensation!

In addition to discovering the presence of life at such a mind-boggling depth, Jacques Piccard was able to experimentally refute the then prevailing opinion that at depths of more than 6,000 m there is no upward movement of water masses. In terms of ecology, this was a major discovery, because some nuclear powers were planning to bury radioactive waste in the Mariana Trench. It turns out that Picard prevented large-scale radioactive contamination of the Pacific Ocean!

After the dive of Walsh and Picard, for a long period only unmanned automatic bathyscaphes descended into the Mariana Trench, and there were only a few of them, because they were very expensive. For example, on May 31, 2009, the American deep-sea vehicle Nereus reached the bottom of the Mariana Trench. He not only took underwater photography and video at incredible depths, but also took soil samples. The instruments of the deep-sea vehicle recorded the depth it reached at 10,902 meters.

On March 26, 2012, a man again found himself at the bottom of the Mariana Trench; it was the famous director, creator of the legendary film “Titanic,” James Cameron.

He explained his decision to make such a dangerous journey to the “bottom of the Earth” as follows: “Almost everything on the earth’s land has been explored. In space, bosses prefer to send people circling around the Earth, and send machine guns to other planets. For the joys of discovering the unknown, there is only one field of activity left - the ocean. Only about 3% of its water volume has been studied, and what’s next is unknown,” Cameron made a dive on the DeepSea Challenge bathyscaphe, it was not very comfortable, the researcher was in a bent state for a long time, since the diameter of the interior of the device was only about 109 cm The bathyscaphe, equipped with powerful cameras and unique equipment, allowed the popular director to film fantastic landscapes of the deepest place on the planet. Later, together with The National Geographic, James Cameron created the exciting documentary “Challenging the Abyss.”

It is worth noting that during his stay at the bottom of the deepest depression in the world, Cameron did not see any monsters, or representatives of an underwater civilization, or an alien base. However, he literally looked into the eyes of the Challenger Abyss. According to him, during his short journey he experienced sensations indescribable in words. The ocean floor seemed to him not only deserted, but somehow “lunar... lonely.” He experienced a real shock from the feeling of “complete isolation from all humanity.” True, problems with the equipment of the bathyscaphe may have interrupted the “hypnotic” effect of the abyss on the famous director in time, and he rose to the surface among the people.

From giant amoebas to underwater bridges

In recent years, many discoveries have been made during the study of the Mariana Trench. For example, in bottom soil samples taken by Cameron, scientists found more than 20 thousand of a wide variety of microorganisms. Among the inhabitants of the depression there are also giant 10-centimeter amoebas, called xenophyophores. According to scientists, single-celled amoebas most likely reached such incredible sizes due to the rather hostile environment at a depth of 10.6 km in which they are forced to live. For some reason, high pressure, cold water and lack of light clearly benefited them, contributing to their gigantism.

Mollusks were also discovered in the Mariana Trench. It is unclear how their shells withstand enormous water pressure, but they feel very comfortable at depth, and are located next to hydrothermal vents that emit hydrogen sulfide, which is lethal to ordinary mollusks. However, local mollusks, having demonstrated incredible abilities for chemistry, somehow adapted to process this destructive gas into protein, which allowed them to live where, at first glance, it was impossible to live.

Many of the inhabitants of the Mariana Trench are quite unusual. For example, scientists discovered here a fish with a transparent head, in the center of which are its eyes. Thus, during the course of evolution, the eyes of the fish received reliable protection from possible injury. At great depths there are many bizarre and sometimes even scary fish; here we managed to capture on video a fantastically beautiful jellyfish. Of course, we don’t yet know all the inhabitants of the Mariana Trench; in this regard, scientists still have many discoveries to make.

There is a lot of interesting things in this mysterious place for geologists. Thus, in a depression at a depth of 414 meters, the Dai-koku volcano was discovered, in the crater of which there is a lake of seething molten sulfur right under the water. As scientists say, the only analogue of such a lake known to them is only on Jupiter’s satellite, Io. Also in the Mariana Trench, scientists found the only underwater source of liquid carbon dioxide on earth, called “Champagne” in honor of the famous French alcoholic drink. There are also so-called black smokers in the depression; these are hydrothermal springs operating at a depth of about 2 kilometers, thanks to which the water temperature in the Mariana Trench is maintained within fairly favorable limits - from 1 to 4 degrees Celsius.

At the end of 2011, scientists discovered very mysterious structures in the Mariana Trench; these are four stone “bridges” stretching from one end of the trench to the other for 69 kilometers. Scientists are still at a loss to explain how these “bridges” arose; they believe that they were formed at the junction of the Pacific and Philippine tectonic plates.

The study of the Mariana Trench continues. This year, from April to July, scientists from the US National Oceanic and Atmospheric Administration worked here on the Okeanos Explorer vessel. Their ship was equipped with a remotely controlled vehicle, which was used to film the underwater world of the deepest place in the World Ocean. The video broadcast from the bottom of the depression could be seen not only by scientists, but also by Internet users.

As children, we all read many legends about incredible sea monsters that inhabit the ocean floor, always knowing that these were just fairy tales. But we were wrong! These incredible creatures can be found even today if you dive to the bottom of the Mariana Trench, the deepest place on Earth. Read our article about what the Mariana Trench hides and who its mysterious inhabitants are.

The deepest place on the planet is the Mariana Trench or Mariana Trench- is located in the western Pacific Ocean near Guam, east of the Mariana Islands, from which its name comes. The shape of the trench resembles a crescent, about 2,550 km long and an average width of 69 km.

According to the latest data, the depth Mariana Trench is 10,994 meters ± 40 meters, which even exceeds the highest point on the planet - Everest (8,848 meters). So this mountain could well be placed at the bottom of the depression, moreover, there would still be about 2,000 meters of water above the top of the mountain. The pressure at the bottom of the Mariana Trench reaches 108.6 MPa - this is more than 1,100 times higher than normal atmospheric pressure.

Man only fell to the bottom twice Mariana Trench. The first dive was made on January 23, 1960 by US Navy Lieutenant Don Walsh and explorer Jacques Piccard in the bathyscaphe Trieste. They stayed at the bottom for only 12 minutes, but during this time they managed to meet flat fish, although according to all possible assumptions there should have been no life at such a depth.

The second human dive took place on March 26, 2012. The third person who touched the secrets Mariana Trench, became a film director James Cameron. He dived on the single-person Deepsea Challenger and spent enough time there to take samples, take pictures and film 3D video. Later, the footage he shot formed the basis of a documentary film for the National Geographic Channel.

Due to the strong pressure, the bottom of the depression is covered not with ordinary sand, but with viscous mucus. For many years, the remains of plankton and crushed shells accumulated there, which formed the bottom. And again, due to pressure, almost everything is at the bottom Mariana Trench turns into fine grayish-yellow thick mud.

Sunlight has never reached the bottom of the depression, and we expect the water there to be icy. But its temperature varies from 1 to 4 degrees Celsius. IN Mariana Trench at a depth of approximately 1.6 km are the so-called “black smokers”, hydrothermal vents that shoot water up to 450 degrees Celsius.

Thanks to this water Mariana Trench life is supported as it is rich in minerals. By the way, despite the fact that the temperature is significantly higher than the boiling point, water does not boil due to very strong pressure.

At approximately a depth of 414 meters is the Daikoku volcano, which is the source of one of the rarest phenomena on the planet - a lake of pure molten sulfur. In the solar system, this phenomenon can only be found on Io, a satellite of Jupiter. So, in this "cauldron" the bubbling black emulsion boils at 187 degrees Celsius. So far, scientists have not been able to study it in detail, but if in the future they can advance in their research, they may be able to explain how life appeared on Earth.

But the most interesting thing about Mariana Trench- these are its inhabitants. After it was established that there was life in the depression, many expected to find incredible sea monsters there. For the first time, the expedition of the research vessel Glomar Challenger encountered something unidentified. They lowered a device into the depression, the so-called “hedgehog” with a diameter of about 9 m, made in a NASA laboratory from beams of ultra-strong titanium-cobalt steel.

Some time after the descent of the apparatus began, the device recording sounds began to transmit to the surface some kind of metallic grinding sound, reminiscent of the grinding of saw teeth on metal. And unclear shadows appeared on the monitors, reminiscent of dragons with several heads and tails. Soon, scientists became worried that the valuable apparatus might remain forever in the depths of the Mariana Trench and decided to lift it onto the ship. But when they removed the hedgehog from the water, their surprise only intensified: the strongest steel beams of the structure were deformed, and the 20-centimeter steel cable on which it was lowered into the water was half sawn through.

However, perhaps this story was too embellished by the newspapers, since later researchers discovered very unusual creatures there, but not dragons.

Xenophyophores are giant, 10-centimeter amoebas that live at the very bottom Mariana Trench. Most likely, due to strong pressure, lack of light and relatively low temperatures, these amoebas acquired enormous sizes for their species. But in addition to their impressive size, these creatures are also resistant to many chemical elements and substances, including uranium, mercury and lead, which are lethal to other living organisms.

Pressure in M ariana trench turns glass and wood into powder, so only creatures without bones or shells can live here. But in 2012, scientists discovered a mollusk. How he preserved his shell is still not known. In addition, hydrothermal springs emit hydrogen sulfide, which is fatal to shellfish. However, they learned to bind the sulfur compound into a safe protein, which allowed the population of these mollusks to survive.

And that is not all. Below you can see some of the inhabitants Mariana Trench, which scientists managed to capture.

Mariana Trench and its inhabitants

While our eyes are directed to the sky towards the unsolved mysteries of space, there remains an unsolved mystery on our planet - the ocean. To date, only 5% of the world's oceans and secrets have been studied Mariana Trench This is only a small part of the secrets that are hidden under the water.
