The deepest points of the oceans. Where is the Mariana Trench located?

IN Everyday life we get used to the fact that the earth is flat and level. Potholes on the roads seem like a personal insult, a depression of 10-20 meters is a serious pit. But behind this routine, we sometimes forget that the topography of our planet is very heterogeneous. About high points We've already talked, and now it's time to look at the other side of this problem and find the deepest place on Earth.

Underwater depths

One of the creatures from the Mariana Trench. It's alive and pretty happy

It may seem like a funny paradox, but some of the deepest points on Earth are located under water. It is in the ocean that numerous trenches are hidden - faults of lithospheric plates. Filled with water, they turned into Amazing places, completely different from the world we are used to. The multi-kilometer layer of water creates unimaginable pressure; not a single ray of sunlight, even the fastest, can pass through this barrier. As a result, it is very dark and difficult there.

There are quite a lot of such points in the world, but the most impressive of them are known to everyone:

1. Mariana Trench. Its bottom is the deepest point Pacific Ocean and the ocean in general. Many times they tried to accurately determine its depth, and according to the latest data it is 10994 meters. This value is difficult to comprehend, but for comparison - the height of Everest, the most high mountain, is just over 8800 metro. Thus, our planet is rather deep than high.
2. Tongo gutter. The second deepest and much less studied trench. Its deepest point is at level 10882, which is only 100 meters less than the Mariana Trench. It turns out that the difference between the two deepest gutters is about 1%. Not so much. But if he loses in depth, he is first in other respects. For some reason, in this place the plates move an order of magnitude faster than in other places. The movement speed is about 25 centimeters instead of the required 2.
3. Philippine Trench. The third deepest point in the World Ocean. The maximum value is 10,265 meters, which is clearly less than that of the Mariana Trench and the Tongo Trench.

The funny thing is that these trenches are quite well studied, unlike most of the seabed. People imagine what is happening on approximately 5% of its area, while the remaining places escape our attention.

At the same time, gutters hide many secrets. For example, previously people did not even think that at such pressure, without light and oxygen dissolved in water, someone could exist. But the expeditions still found quite cheerful, albeit strange creatures there. And this is just one of many surprises that human nature has prepared.

Wells

Despite the fact that the underwater faults and trenches created by nature itself are amazing, the deepest place is still the work of man. And these are wells.

This is what KS-3 looks like from the outside. And under the cover - 12 kilometers of puncture

If a fault is an open wound on the body of the planet, then a well is more like a trace of an injection from the thinnest needle, but sometimes they can bring no less surprises and unexpected data. And the following wells boast the most impressive depth:

1. Kola superdeep well. Its total depth is 12263 meters. At the same time, the diameter of the outer part of the well is only about half a meter. The purpose of creating this well was to obtain new data on the structure of the earth's crust. And scientists received them in full. The study of this place brought them an incredible amount of new and unexpected information, which significantly influenced people’s ideas about the structure of our planet.
2. OR-11. Another well created by Russian engineers. It belongs to the Sakhalin-1 project, within the framework of which the field was studied. Its depth is 11,345 meters, a very impressive achievement. In total, 10 wells were drilled as part of this project.
3. BD-04A. This well, located in Qatar, was created with one very specific purpose - to study the oil field. Exploration required some effort, first of all, the creation of one of the deepest wells - 10,092 meters.

It turns out that the deepest place on the planet is still the fruit of human hands. And even if this mistake is infinitely small, the achievement cannot but rejoice.

Among the deepest places on the planet there are both natural and man-made. Whatever the history of their appearance, this does not make these depressions and mines any more mysterious.

No. 10. Lake Baikal - 1,642 m

Baikal has a depth of 1,642 meters and is the deepest among the lakes. Locals That’s why Baikal is often called the sea. This depth is explained tectonic origin lakes.

Many other records and amazing discoveries are associated with this place. Baikal can be called the largest natural reservoir fresh water on the ground. Exactly this ancient lake on our planet (it is more than 25 million years old) and two-thirds of the flora and fauna of the reservoir are found nowhere else.

No. 9. Krubera-Voronya Cave – 2,196 m

The Krubera-Voronya cave (Abkhazia) is one of the deepest places on Earth. And we are talking only about the studied part of the cave. It is possible that the next expedition will go even lower and set a new depth record.

The karst cave consists of wells connected by passages and galleries. It was first opened in 1960. Then speleologists were able to descend to a depth of 95 meters. The two-kilometer limit was overcome by a Ukrainian expedition of speleologists in 2004.

No. 8. TauTona Mine - 4,000 m

Located in the Republic of South Africa, near Johannesburg. This world's largest gold mine goes 4 kilometers into the ground. At this incredible depth there is a whole underground city with a network of kilometer-long tunnels. To get to their workplace, miners have to spend about an hour.

Working at such a depth is associated with a large number of dangers - humidity, which reaches 100% in some branches of the mine, high air temperatures, the danger of an explosion from gas leaking into the tunnels and collapse from earthquakes, which occur here quite often. But all the dangers of work and the costs of maintaining the functionality of the mine are generously paid for by the mined gold - over the entire history of the mine, 1,200 tons of the precious metal were mined here.

No. 7. Kola well - 12,262 m

Located on the territory of Russia. This is one of the most unusual and interesting experiments carried out by Soviet scientists. Drilling began in 1970 and had only one goal - to learn more about the Earth's crust. The Kola Peninsula was chosen for the experiment because the oldest rocks on Earth, about 3 million years old, come to the surface here. They were also of great interest to scientists.

The depth of the well is 12,262 meters. It made it possible to make unexpected discoveries and forced us to reconsider scientific ideas about the occurrence of rocks on the Earth. Unfortunately, the well, created for purely scientific purposes, did not find use in subsequent years, and a decision was made to mothball it.

No. 6. Izu-Bonin depression - 9,810 m

In 1873-76, the American oceanographic vessel Tuscarora surveyed the seabed for laying an underwater cable. The lot, abandoned off the Japanese Izu Islands, recorded a depth of 8,500 meters. Later, the Soviet ship "Vityaz" in 1955 explored and established the maximum depth of the depression - 9810 meters.

No. 5. Kuril-Kamchatka Trench - 10,542 m

The Kuril-Kamchatka Trench is not only one of the deepest places on Earth, the trench is also the narrowest in the Pacific Ocean. The width of the trench is 59 meters, and the maximum depth is 10,542 meters. The depression is located in the northwestern part of the Pacific Ocean. In the middle of the last century, Soviet scientists studied it on the Vityaz ship. No further detailed studies have been carried out. The trench was discovered by the American ship Tuscarora and bore this name for a long time until it was renamed.

No. 4. Kermadec Trench - 10,047 m

Located in the Pacific Ocean near the Kermadec Islands. The maximum depth of the depression is 10,047 meters. Explored by the Soviet ship "Vityaz". In 2008, a previously unknown species of sea slug from the snail fish family was discovered at a depth of 7 kilometers in the Kermadec Trench. The researchers were also surprised by other dwellings of this deepest place on Earth - huge 30-centimeter crustaceans.

There are deep faults in the earth's crust - sea depressions at the bottom of the oceans, where impenetrable darkness and the highest pressure reign. We offer a selection of the deepest sea depressions, which the lack of technology does not yet allow to study well.

1. Mariana Trench

The Mariana Trench is the deepest oceanic trench on our planet, which is located in the Pacific Ocean not far from the trench that gave it its name Mariana Islands. The depth of the trench is 10994 ± 40 m below sea level.

Paradoxically, the Mariana Trench has been more or less explored - three people have already descended here.

The first time this happened was on January 23, 1960, when the bathyscaphe, on board which were US Navy Lieutenant Don Walsh and researcher Jacques Piccard, managed to sink to a depth of 10,918 m. Then there were no such technologies as there are now, and two people were connected to the world only by a strong cable. After a successful return, the researchers said that they saw flat flounder-like fish at the very bottom, but, unfortunately, there were no photographs.

Just a year ago, director James Cameron descended to the bottom of the Mariana Trench. It was easier for him, even though he was alone: ​​in 50 years, technology has moved far forward. Moreover, his bathyscaphe “Deepsea Challenger” was equipped with everything necessary for photo and video shooting, and there were also 3D cameras on board. Based on the material received, the National Geographic channel is preparing a film.

And recently, information was received that there are real mountains at the bottom of the Mariana Trench: using echolocation, it was possible to “see” four ridges 2.5 km high.

2. Tonga Trench

The Tonga Trench is the deepest trench in the Southern Hemisphere and the second deepest on Earth. The maximum known depth is 10,882 m. It is unusual primarily because the speed of movement of lithospheric plates in the Tonga region is much greater than in all other parts of the planet where there are breaks in the earth's crust. Here the plates move at a speed of 25.4 cm per year versus the usual 2 cm. This was established by observing the tiny island of Niautoputanu, which moves by an average of just 25 cm every year.

Somewhere in the middle of Tonga, the Apollo 13 lunar landing stage was stuck, having fallen there during the lunar module's return to Earth. It is located at a depth of approximately 6,000 m, and no attempts have been made to extract it from there. Along with it, a plutonium energy source containing plutonium-238 fell into the waters of the Pacific Ocean. It seems that this did not cause much harm to the environment, although given that the half-life of plutonium-238 is slightly less than 88 years, and the module fell there in 1970, very interesting discoveries may await pioneers who decide to go down to the bottom of Tonga.

3. Philippine groove

The Philippine Trench is also located in the Pacific Ocean near the Philippine Islands. The maximum depth is 10,540 m. Little is known about the trench - only that it was formed as a result of subduction. No one tried to go down to its bottom, since the Mariana Trench, of course, is more interesting.

4. Kermadec gutter

The Kermadec connects to the north with the Tonga Trench. The maximum depth is 10,047 m. During an expedition in 2008, it was possible to photograph a strange pink creature of the species Notoliparis kermadecensis at a depth of 7,560 m. Other inhabitants were also found there - huge crustaceans 34 cm in length.

5. Izu-Bonin Trench

The maximum depth of the Izu-Bonin Pacific Trench, also known as Izu-Ogasawara, is 9,810 m. It was discovered at the end of the 19th century during an expedition when it was decided to lay a telephone cable along the ocean floor. Of course, it was first necessary to take measurements, and in one place, not far from the Izu Islands, the Tuscarora vessel’s lot did not reach the bottom, recording a depth of more than 8,500 m.

In the north, Izu-Ogasawara connects with the Japan Trench, and in the south with the Volcano Trench. There is a whole chain of deep-sea depressions in this area of ​​​​the ocean, and Izu-Bonin is just part of it.

6. Kuril-Kamchatka Trench

This depression was discovered shortly after Izu-Bonin during the same expedition. The maximum depth is 9,783 m. This trench is quite narrow compared to all the others, its width is only 59 m. It is known that on the slopes of this trench there are ledges, terraces, canyons and valleys that appear up to the maximum depth. The bottom of the Kuril-Kamchatka Trench is uneven, divided by rapids into separate depressions. To our knowledge, no detailed studies have been carried out.

7. Puerto Rico Trench

The Puerto Rico Trench is located on the border of the Atlantic Ocean and Caribbean Sea. The maximum depth is 8,385 m, and this is the deepest place in Atlantic Ocean. The area where the trench is located is a zone of high seismic activity. The last disaster occurred here in 2004, when underwater volcanic eruptions caused a tsunami that hit the countries Indian Ocean. Recent studies have shown that perhaps the depth of the trench is gradually increasing due to the fact that the North American tectonic plate - the southern “wall” of the trench - is gradually descending.

At a depth of 7,900 m in the Puerto Rican Trench, an active mud volcano was discovered, which erupted rock 10 km high in 2004. A column of hot mud and water was clearly visible above the surface of the ocean.

8. Japanese groove

The Japan Trench is also located in the Pacific Ocean, as the name suggests, located near the Japanese Islands. The depth of the Japan Trench, according to the latest data, is about 8,400 m, and the length is more than 1,000 km.

No one has yet reached its bottom, but in 1989, the Shinkai 6500 bathyscaphe with three researchers on board sank to 6,526 m. Later, in 2008, a group of Japanese and British researchers managed to photograph large groups of fish 30 cm long at a depth of 7,700 m.

Where is the deepest place on Earth? How far is it from the center of the Earth? If Everest was placed there, would it rise above the surface of the Earth?
Today we will deal with the most deep places, holes, wells, caves, wells in the world, natural and man-made

1.8 meters

Graves are usually dug at this depth. It is from this depth that the zombies will emerge when the time comes.

Here are the famous Parisian Catacombs - a network of winding underground tunnels and man-made caves beneath Paris. The total length, according to various sources, is from 187 to 300 kilometers. Since the end of the 18th century, the remains of almost six million people have been buried in the catacombs.

40 meters

The Terme Millepini hotel in Italy chose this bold strategy, digging a 40-meter-deep tunnel for snorkelers and divers. This is the Y-40 pool. The most interesting thing about the Y-40 deepest pool is that it is filled with thermal water and has a wonderful temperature of 33 degrees Celsius.

105.5 meters

This is the depth of the Arsenalnaya metro station of the Kyiv metro, which is located on the Svyatoshinsko-Brovarskaya line between the Khreshchatyk and Dnepr stations. This is the deepest metro station in the world.

122 meters

Tree roots can penetrate to this depth. The tree with the deepest roots is a wild ficus growing at Echo Caves near Ohrigstad, South Africa. This tree is native to South Africa. Its roots go almost 122 meters deep.

230 meters

The deepest river. This is the Congo - a river in Central Africa. In the lower reaches of the Congo breaks through the South Guinea Highlands in a deep narrow (in some places no more than 300 meters) gorge, forming the Livingston Falls (total drop 270 meters), the depths in this area are 230 meters or more, which makes the Congo the deepest river in the world .

240 meters

This is the Seikan Tunnel railway tunnel in Japan, 53.85 km long. The tunnel descends to a depth of about 240 meters, 100 meters below the seabed. It is the deepest under the seabed and the second longest (after the Gotthard Base Tunnel) railway tunnel in the world.

287 meters

Even deeper is the Eiksund road tunnel, laid along the bottom of the Storfjord in Norwegian province Møre og Romsdal, connects the cities of Eiksund and Rjanes. Construction began in 2003, the opening ceremony took place on February 17, 2008, full traffic opened on February 23, 2008. With a length of 7765 m, the tunnel goes to a depth of 287 m below sea level - this is the most deep tunnel in the world. The slope of the road surface reaches 9.6%.

382 meters

Woodingdean is an eastern suburb of Brighton and Hove, located in East Sussex, England. It is notable for the fact that it contains the deepest well in the world, dug by hand between 1858–1862. The depth of the well is 392 meters.

Of course, it doesn't look so picturesque, it's just an illustration.

603 meters

"Cave of Vertigo" Vrtoglavica in the Julian Alps. It is located on the territory of Slovenia, near the border with Italy). The cave was discovered by a joint Slovenian-Italian group of speleologists in 1996. The cave contains the deepest karst well in the world, its depth is 603 meters.

The North Tower of the World War II could easily fit here. shopping centers in New York (its height is 417 m, and taking into account the antenna installed on the roof - 526.3 m).

If you accidentally fall into this hole, you can reach the bottom in 11 seconds.

700 meters

33 miners were trapped under the rubble as a result of the collapse of the San Jose mine on August 5, 2010. They were held captive at a depth of 700 meters for more than 2 months and were considered dead for almost 3 weeks. As a result of 40 days of work, a well was drilled to rescue Chilean miners.

970 meters

This is the largest dug hole in the Earth, from the bottom of which you can still see the sky. The Bingham Canyon Quarry in Utah is one of the largest man-made (man-dug) formations in the world. After more than 100 years of mining, a large crater was formed, 970 meters deep and 4 km wide. This unique canyon was designated a National Historic Landmark in 1966.

The entire Burj Khalifa will fit into this quarry - the most tall building in the world ever created, whose height is 828 meters. And not only will it fit, but from its “top” there will be more than 140 meters to the surface.

On April 10, 2013, a giant block of earth broke off and rushed into a huge hole in the artificial Bingham Canyon in Utah. Approximately 65 - 70 million cubic meters of earth thundered along the walls of the mine, reaching speeds of up to 150 kilometers per hour. The event was so powerful that it shook the earth - seismic sensors were activated, recording the earthquake. Intensity was measured as 2.5 on the Richter scale.

1642 meters

Baikal is the deepest lake on Earth. The current maximum depth of the lake is 1642 m.

1857 meters

The Grand Canyon is one of deepest canyons in the world. Located on the Colorado Plateau, Arizona, USA. Depth - more than 1800 m.

2199 meters

So we reached the deepest cave in the world. This is the Krubera (Voronya) cave - the only famous cave in the world deeper than 2 kilometers. The main entrance to the cave is located at an altitude of about 2250 m above sea level.

3132 meters

Today, the deepest mine is the Moab Khotsong mine in South Africa, located southwest of Johannesburg. Its depth is a little over 3 kilometers. The elevator takes 4.5 minutes to reach the very bottom, but you can speed up the process: if a person accidentally falls here, the flight to the bottom will take him 25 seconds.

3600 meters

A living organism was found at this depth. About a hundred years ago, the English scientist Edward Forbes argued that there are no living creatures deeper than 500 meters. But in 2011, in a gold mine on the territory South Africa nematode worms Halicephalobus mephisto were found. The second name for these 0.5 mm creatures is “worm from hell.”

4500 meters

The deepest mines in the world are located in South Africa: Tau-Tona, Witwatersrand - depth more than 4500 m, Western Deep Levels Mine - 3900 m (De Beers company), Mponeng - 3800 m. For miners have to work in extreme conditions. The heat reaches 60 °C, and at such depths there is always the danger of water breakthrough and explosions. These mines produce gold. The journey here takes miners about 1 hour.

By the way, from 25 to 50% of the gold mined in the world is obtained from the Witwatersrand deposit. Extraction is carried out, among other things, from the deepest mine in the world, “Tau-Tona” - its depth is more than 4.5 km, the temperature in the workings reaches 52 degrees.

A piece of gold-bearing ore mined at the deposit:

Let's move on. What follows will be very deep.

10994 meters

The Mariana Trench (or Mariana Trench) is an oceanic deep-sea trench in the western Pacific Ocean, the deepest known on Earth. Named after the nearby Mariana Islands. The deepest point of the Mariana Trench is the Challenger Deep. According to measurements in 2011, its depth is 10,994 m below sea level.

This is very deep. If Everest, 8848 meters high, could be placed here, then there would still be more than 2 km left from its top to the surface.

Yes, there is a place on Earth about which we know much less than about distant space - the mysterious bottom of the ocean. It is believed that world science has not yet really even begun to study it...

At a depth of 11 kilometers. At the bottom, the water pressure reaches 108.6 MPa, which is approximately 1072 times greater than normal atmospheric pressure at the level of the World Ocean.

12262 meters

We have reached the deepest well in the world. This is the Kola superdeep well. Located in the Murmansk region, 10 kilometers west of the city of Zapolyarny. Unlike other ultra-deep wells that were drilled for oil production or geological exploration, SG-3 was drilled solely for scientific research purposes in the place where the Mohorovicic boundary comes close to the surface of the Earth.

At a depth of five kilometers, the ambient temperature exceeded 70 °C, at seven - 120 °C, and at a depth of 12 kilometers, sensors recorded 220 °C.

Kola superdeep well, 2007:

The Kola Superdeep served as the source of the urban legend about the “well to hell.” This urban legend has been circulating the Internet since at least 1997. For the first time on English language The legend was announced in 1989 on the American television company Trinity Broadcasting Network, which took the story from a Finnish newspaper report published on April Fool's Day. According to this legend, in the very thickness of the earth, at a depth of 12,000 meters, microphones of scientists recorded screams and moans. The tabloid newspapers write that this is “a voice from the underworld.” The Kola superdeep well began to be called “the road to hell” - every new kilometer drilled brought misfortune to the country.

If you drop something into this hole, it will take 50 seconds before that “something” falls to the bottom.

This is it, the well itself (welded), August 2012:

12376 meters

Well Z-44 Chaivo, which was drilled in Russia on the shelf of Sakhalin Island, is considered the deepest in the world oil well. It goes to a depth of about 13 kilometers - this depth is comparable to the height of 14.5 skyscrapers Burj Khalifa, which remains the tallest in the world. This is the deepest hole that humanity has been able to drill.
On this moment, this is the deepest place in the world. And it is located only at a depth of about 12.4 km. Is this too much? Let us remember that the average distance to the center of the Earth will be 6371.3 kilometers...

The bottom of the world's oceans is uneven, cut through by gorges whose depth is tens of thousands of meters. The relief was formed millions of years ago due to the movement of tectonic plates - the “shell” of the earth’s crust. Due to their continuous movement, the location and shape of the continents and the ocean floor changed. The deepest ocean on the planet is the Pacific Ocean, which at this stage of technological development cannot be fully explored.

The Pacific Ocean is the largest on the planet. In its western latitudes lie the continents of Australia and Eurasia, in the southern - Antarctica, in the eastern - South and North America. The length of the Pacific Ocean from south to north is almost 16 thousand kilometers, and from west to east - 19 thousand. The area of ​​the ocean together with its seas is 178.684 million kilometers, and the average depth is about 4 kilometers. But there are amazing places in the Pacific Ocean that make it the deepest in the world.

The Mariana Trench is the deepest place in the ocean

This deepest chasm got its name in honor of the nearby Mariana Islands. The depth of the Pacific Ocean in this place is 10 kilometers 994 meters. The deepest point of the trench is called the Challenger Deep. Geographically, the “Abyss” is located 340 km from the southwestern tip of the island of Guam.

If we take Mount Everest for comparison, which, as is known, rises 8848 m above sea level, it can completely disappear under water and there will still be room.

In 2010, an oceanographic expedition from New Hampshire conducted research on the ocean floor in the Mariana Trench area. Scientists have discovered four seamounts, each at least 2.5 kilometers high, crossing the surface of the trench at the point of contact between the Philippine and Pacific lithospheric plates. According to scientists, these ridges were formed about 180 million years ago as a result of the movement of the above-mentioned plates and the gradual creep of the older and heavier Pacific Plate under the Philippine Plate. The maximum depth of the Pacific Ocean was recorded here.

Diving into the abyss

Deep-sea vehicles with three people descended into the depths of the Challenger Deep four times:

1. Brussels explorer Jacques Piccard together with Lieutenant American Navy John Walsh were the first to dare to look into the face of the abyss. This happened on January 23, 1960. The deepest dive in the world was made on the bathyscaphe Trieste, designed by Auguste Piccard, Jacques' father. This feat, without a doubt, set a record in the world of deep diving. The descent lasted 4 hours 48 minutes, and the ascent lasted 3 hours 15 minutes. The researchers found large flat fish at the bottom of the trench that looked like flounder. The lowest point of the World Ocean was recorded - 10,918 meters. Later, Picard wrote the book “11 thousand meters”, describing all the moments of the dive.
2. On May 31, 1995, a deep-sea Japanese probe was launched into the depression, which recorded a depth of 10,911 m and also discovered ocean inhabitants - microorganisms.
3. On May 31, 2009, the Nereus automatic apparatus went on reconnaissance and stopped at 10,902 m. It shot a video, took pictures of the bottom landscape and collected soil samples, in which microorganisms were also found.
4. Finally, on March 26, 2012, film director James Cameron accomplished the feat of diving solo into the Challenger Deep. Cameron became the third person on Earth to visit the bottom of the World Ocean at its very core. deep place. The single-seat Deepsea Challenger was equipped with advanced deep-sea imaging equipment and powerful lighting equipment. Filming was carried out in 3G format. The Challenger Deep is featured in James Cameron's National Geographic Channel documentary.

This depression is located at the junction of the Indo-Australian plate and the Pacific plate. Extends from the Kermadec Trench towards the Tonga Islands. Its length is 860 km and its depth is 10,882 m, which is a record in the Southern Hemisphere and the second deepest on the planet. The Tonga region is notorious for being one of the most active seismic zones.

In 1970, on April 17, during Apollo 13's return to earth, the spent landing stage containing plutonium fell into the Tonga Trench to a depth of 6 km. No attempts were made to remove her from there.

Philippine Trench

The second deepest place in the Pacific Ocean is located in the Philippine Islands. The recorded depth of the depression is 10,540 m. The depression was formed as a result of the collision of granite and basalt layers, the latter, being heavier, was undermined by the granite layer. The process of meeting two lithospheric plates is called subduction, and the place of “meeting” is the subduction zone. In such places, tsunamis are born and earthquakes occur.

The depression runs along a volcanic ridge Kuril Islands on the border between Japan and Russia. The length of the trench is 1300 km, and the maximum depth is 10500 m. The depression was formed more than 65 million years ago during the Cretaceous period as a result of the collision of two tectonic plates.

It is located near the Kermadec Islands, northeast of New Zealand and in the southwest Pacific Ocean. The trench was first discovered by the Galatea group from Denmark, and the Soviet research vessel Vityaz studied the bottom of the trench in 1958 and recorded a maximum depth of 10,047 m. In 2008, an unknown species of sea slugs was discovered at the bottom of the trench, as well as deep-seated crustaceans long up to 30 cm.

Our blue planet is full of secrets, and we humans strive to comprehend them. We are curious by nature, learning from the past and looking forward to the future. The ocean is the cradle of humanity. When will he reveal his secrets to us? The greatest depth of the Pacific Ocean that is known to scientists - are these figures true, or is there something incomprehensible hidden under the black water?
