Which sea is the deepest in the world? The largest seas in the world - Sargasso, Philippine and others The deepest sea in the world

Sea depths mysterious, there is still a lot of unknown in them to this day. Despite all the technological progress, the abyss of water remains largely unexplored, and people know little more about them than about space.

It is not surprising that every year it is possible to discover new species of fish and other marine life, and make new discoveries at the bottom and in the water column.

And even regarding the depth of the seas and their deepest points, scientists do not deny that new discoveries can occur at any moment. However, the rating is most deep seas already exists, and it is worth studying - if only in order to understand the reason for the lack of knowledge of the water abyss. After all, diving to such depths is really problematic and unsafe!

Fifth place - Weddell Sea

This sea ranks fifth in depth, its deepest point is at 6820 meters below surface level. It is located near Antarctica, washing its shores, limited to the Antarctic Peninsula. The greatest depth is in the northern part, South part The water area remains relatively shallow. Icebergs roam this sea, and the climate here is not very hospitable.

Fourth place - Caribbean Sea

Despite its small size, it is an exceptionally deep body of water, which is located between the South and Central America. Its depth reaches 7090 meters, and the bottom is strewn with treasures - this is exactly what treasure hunters think. In fact, they are close to the truth, because many galleons carrying New World gold sank here, and the place was known for pirate activity. But you should look for jewelry in the lowlands of the seabed, and diving to such depths requires special equipment, which requires a lot of effort and huge investments. And therefore the riddles Caribbean Sea still excites minds. The Caribbean Sea refers to the water area Atlantic Ocean.

Third place - Banda Sea

The Banda Sea has a maximum depth of about 7440 meters. This body of water is located near Indonesia and is famous for its rich natural world. Rare dolphins, jellyfish and octopuses, nautiluses, stingrays, sea ​​snakes, and many other living creatures. This sea belongs to the Pacific Ocean.

Just as the bottom of the Caribbean Sea is hypothetically strewn with jewels, so the bottom of this sea is also full of riches, but only natural ones. After all, the closer to the bottom, the higher the depth, the more rare and unique species manages to meet.

Second place – Coral Sea

The Coral Sea is also classified as a Pacific Ocean and borders the Philippine Islands. The average depth here is 4 km, which is quite trivial, but there are places with deep-sea depressions. It is also worth pointing out that many scientists “donate” the famous Mariana Trench to this body of water, and not to the Philippine Sea, so its placement in the list of the deepest is quite natural.

The deepest sea in the world

The deepest sea in the world is the Philippine Sea. And since two seas have to share the deepest mark on the planet, then the Philippine Sea should rightfully take first place. The lower mark is 9140 meters, and the reservoir again belongs to the Pacific Ocean. The mark falls on the Mariana Trench, which is a trench going into the deeper layers earth's crust. Considering volcanic activity at the bottom of the reservoir, one should not be surprised at the presence of such an object here. Also at depth it is possible to discover “black smokers” and other objects that demonstrate volcanic activity and create a unique natural world around them. The Mariana Trench is of great interest, dives are carried out in it, but no one has been to its very bottom yet.

Depth of Russian seas

In general, it is the seas Pacific Ocean turn out to be the deepest, and this is especially true for areas near Australia, New Guinea, and the Philippines. Together with the enormous depth, these waters delight with wealth and abundance. natural world, because there are corals, flying fish, and many other exotics that are still being studied by biologists. However, the Russian seas are not so deep, and they definitely will not be included in the list of the first five. Only the Bering Sea is worth noting.

This the deepest of the Russian seas, its depth reaches 4151 meters. It is located between Siberia and Alaska, separating two continents, North America and Eurasia. Scientists believe that during the last great glaciations, this sea shallowed, creating an isthmus along which animals could move and people could migrate, populating the continents. A The Sea of ​​Azov does not exceed 15 meters in depth.

Deep waters are fraught with many mysteries that to this day excite the minds of people, causing periodic sensations, even assumptions about the presence intelligent life. And even if humanity will one day be able to fully explore and develop the seas and oceans, this will not happen soon.

The deepest sea in Russia is the Bering Sea, named after the Danish-born Russian naval officer Vitus Bering, who explored this rough, deep northern sea in the mid-18th century. Before accepting your official name The Bering Sea was called Kamchatka or Bobrov. Its average depth is about 1600 meters. In the most deep places the recorded depth was 4151 meters. About half of the area is occupied by spaces with a depth of more than 500 meters, while its entire area is more than 2315 thousand square kilometers.

The Bering Sea is not only the deepest, but also the northernmost body of water in Russia. The sea becomes covered with ice in September and is cleared only by June, while ice can cover up to half the area of ​​this reservoir. In the coastal zone and bays, ice forms impassable fields, but the open part of the sea is never completely covered with ice. The ice in the open part of the Bering Sea is in constant movement under the influence of winds and currents, and ice hummocks up to 20 meters high often form.

Despite its depth, the Bering Sea is not even among the ten deepest seas in the world rankings. It belongs to the Pacific Ocean, separated from it by the Aleutian and Commander Islands, and along it runs a section of the water border between Russia and the United States. The Bering Strait connects the Bering Sea with the Chukchi Sea and the Arctic Ocean.

The shallowest sea in Russia

The shallowest sea in Russia is the Azov Sea. Its average depth is only about 7 meters, the maximum does not exceed 13.5. The Sea of ​​Azov is the most shallow sea not only in Russia, but also in the world.

The Sea of ​​Azov belongs to the Atlantic Ocean basin, is an inland sea in eastern Europe, connected by the Kerch Strait to the Black Sea, and is located between Russia and Ukraine. The Sea of ​​Azov is not only the shallowest, but also one of the smallest seas in the world. Its maximum length is 380 km, maximum width is 200 km, coastline 2686 km, surface area 37800 sq. km.

Inflow river waters in the Sea of ​​Azov it is abundant and accounts for up to 12% of the total water volume. The main influx is in its northern part, so the water there contains very little salt and easily freezes in winter. In winter, up to half the sea area is covered with ice, and ice can be carried into the Black Sea through the Kerch Strait.

In summer, due to its shallow depth, the Sea of ​​Azov quickly and evenly warms up to average temperature 24 – 26 degrees, which makes it great place for recreation and fishing.

The depths of the seas and oceans are fraught with a lot of secrets. The desire of scientists to study the depths of the waters in as much detail as possible from year to year brings new invaluable knowledge to humanity. But this is only a grain in the study of 71% of the planet's territory, which is occupied by water.

On this moment you can know exactly how many seas there are in the world, which ones are the largest, and which ones are incredibly deep. Let's take a closer look at these facts.

The largest seas on Earth

Sargasso Sea – quiet and dangerous

The area of ​​this giant is about 6-7 million km². You definitely wouldn’t want to get lost here or be left dangling in a boat after a wreck. It is said that the Sargasso Sea is home to one of the largest ship graveyards. It is not entirely easy to swim away from this body of water, because it is located in the area of ​​​​the anticyclonic water cycle, in simple words– there is practically no current here.

Interestingly, the entire surface of the water is covered with Sargassum algae. Their number, according to rough estimates by scientists, is estimated at 4-11 million tons. That is why many animals live in this reservoir.

The Sargasso Sea is an impressive distance from the nearest shores of the ominous volcanic Bermuda Islands (triangle). For relaxation, it is better to choose another body of water, because here, under the algae constantly floating on the surface, there lurks an incredible danger - powerful underwater eddies formed by different currents. Considering the maximum depth of 6995 m, it’s scary to imagine where one of these craters could drag you down. They have a bizarre effect on the water temperature: in one place it can be +18 ° C, and in the other - +28 ° C. Additional horror is caused by the phenomenal level of the Sargasso Sea, which is significantly higher than the surrounding waters.

Such a huge reservoir cannot but impress, however, this did not stop people from polluting it. The Sargasso Sea is known for its large garbage patch of various plastic waste. All the rubbish thrown into the oceans of the planet accumulates here.

Philippine Sea - deep and unknown

This body of water is completely at the mercy of the Pacific Ocean. If you suddenly want to check for yourself how large its area and depth are, you will have to go to the Philippine archipelago, where this sea is located. The reservoir does not have clear land boundaries, and is separated from the ocean by a number of islands where you can relax: Taiwan, Honshu, Izu, Yap, Ryukyu, Palau and others. The Philippine Sea is, first of all, known as the deepest sea on Earth, since it is here that the ominous Mariana Trench is located with a depth of 11,022 m.

The area of ​​the reservoir is only 5726 thousand km². By the way, not all scientists believe that this trench is part of the Philippine Sea; rather, it is located in the Pacific Ocean. In addition to the impressive depth, this reservoir contains anomalous zone with increased seismic activity. That's why earthquakes most often occur here.

The coral sea is extraordinary

This reservoir is known primarily not for its impressive area of ​​4,791 thousand km² or its maximum depth of 9,140 m. This reservoir was glorified by its outstanding Big barrier reef- the largest coral reef in the world. However, it is threatened by pollution (from the Australian population) and the gradual decline of the ichthyofauna (from poachers breaking off the reefs for sale, and Crown of Thorns starfish eating masses of reef-forming coral polyps).

Territory coral sea refers to Australia and the Pacific Ocean. Also nearby there is New Guinea and New Caledonia. There are a lot of islands scattered across the entire area of ​​the reservoir, which are mostly uninhabited; only Willis Island has a lone meteorological station.

The Bering Sea is the largest in Russia

Its area is 2315 thousand km², and its maximum depth is 4151 m. Interestingly, the reservoir is located in three climatic zones– subarctic, arctic, temperate. Violent winds often blow here, creating incredible strength storms and waves up to 10 m in height.

The Red Sea is beautiful and clean

No matter how enchanting the coral reef is, the Red Sea is considered the most beautiful sea on the planet. Here, lovers of diving and simple tourism will find unforgettable landscapes. Jacques-Yves Cousteau himself filmed the film “The World of Silence” in its waters. The Red Sea is located in Egypt. According to biblical legend, it was these waters that Moses opened in order to guide his flock through.

The Red Sea is a record holder among all others. In addition to the title of the most beautiful, it bears the title of the cleanest and warmest body of water on Earth. The ecosystem can recover at incredible speed. The Suez Canal does practically no harm to it. The air temperature on the coast in winter reaches 25 °C, and in summer – 35-40 and even 50 °C.

The water here evaporates very quickly. About 100 mm of precipitation falls annually, and sometimes even less. Most often it rains in winter. But 2 thousand mm of water evaporates per year, that is, 20 times more than precipitation brings. Fortunately, the resources of this reservoir are replenished either from land or from the Gulf of Aden.

The smallest sea

If we're talking about In terms of depth, the Sea of ​​Azov is considered the shallowest, with a maximum depth of 14 m. And if we talk about area, the Sea of ​​Marmara is considered the smallest. Its area is only 11 thousand km², but its depth is more impressive - 1355 m. Interestingly, this body of water serves as a connection between Europe and Asia, connecting the continents with a one and a half kilometer bridge.

The world's oceans are the most amazing and least studied object on our planet. How many mysteries it contains, and how many discoveries remain to be made by people studying the deepest seas and oceans on our planet.

The deepest seas in the world

The Pacific Ocean has broken all records for depth and is home to four of the six deepest seas in the world. If you line up the seas by depth, both by height, in meters and kilometers, then their leaders are: the Philippine Sea and the Coral Sea, followed by the Banda Sea, the Caribbean Sea, the Weddell Sea and the Tasman Sea.

In first place is the Philippine Sea. It is located in the Pacific Ocean, near the Philippine archipelago. It is to this sea that the deepest oceanic trench is attributed - the Mariana Trench, thus the greatest depth of the Philippine Sea is 11022 meters. Even average depth this sea is more than 4 km, while the depth of the Sea of ​​Azov, for example, does not exceed 14 meters.

There are volcanoes at the bottom of the Philippine Sea. Because of enormous depth Marine life Here, mainly those found in surface and coastal waters have not been fully studied. It is known that in the Philippine Sea they live sea ​​turtles, dolphins, swordfish, various shellfish. In addition, there are a lot of sharks that are dangerous to humans, including tiger and gray shark. But the large deep-sea inhabitants of the Mariana Trench are definitely predators, and what kind of ones at that! Most of all they look like monsters with many teeth and huge jaws. Not everyone has eyes deep sea fish, and if there are, then they are not at all similar to those familiar to us, because at the bottom of the depression there is complete darkness. But many have very developed organs that detect sounds. There are also simple organisms there that have existed for billions of years.

The second place is occupied by the Coral Sea, with a depth of 9140 meters, one of the most beautiful seas in the world. This sea is also located in the Pacific Ocean, off the coast of New Guinea and Australia. The Coral Sea is characterized by a large number of islands, and of course, many coral reefs. The most famous of them is the Great Barrier Reef. Among the inhabitants of the Coral Sea - sea ​​stars, hedgehogs and turtles, flying fish, a lot various types shrimp, crustaceans and crabs.

Third place rightfully belongs to the not very large, but very deep (up to 7440 meters) Banda Sea. It is located off the coast of Indonesia, and also belongs to the Pacific Ocean. This is a volcanic zone and the islands in the Banda Sea are of volcanic origin. This sea is home to dolphins, squids, jellyfish, octopuses, nautiluses, sharks, stingrays, and even sea snakes.

The Caribbean Sea is in fourth place in the depth ranking. It is located in the Atlantic Ocean between South and Central America. The depth of this sea is 7090 meters, and among the depressions and rises at the bottom lie sunken frigates and galleons. The search for sunken treasure continues to this day, and many countries dispute the ownership of these treasures.

How deep is the Black Sea?

The Black Sea is not the deepest sea in the world, but among inland seas in our country it ranks first - its greatest depth is 2258 meters. Compared with Sea of ​​Azov, whose depth is only about 14 meters, or the Baltic (500 meters is the greatest distance to the bottom), the Black Sea is very deep. It also differs from other seas in our country in that part of its shores are mountains (the Caucasus, the southern coast of Crimea), which go into the water at a steep angle. Because of this, the bottom slope in these places is greater. But there is also shallow water - this is the northwestern part of the Black Sea.

The deepest sea in Russia

Russia is a huge country, and its shores are washed by many seas, but most of them are in the North and East of the country. But near the Northern seas Arctic Ocean there is no such depth and size as the seas of the Pacific Ocean, located off the eastern coast of our country. This is explained by the structure of the earth's crust in those places. Three seas are located in the Pacific Ocean in eastern Russia: the Sea of ​​Japan, the Sea of ​​Okhotsk and the most northern of them - the Bering Sea. They are separated from the ocean itself by islands (Kuril, Japanese and Aleutian).

Next come the ocean depressions, including one of the deepest in the world - the Kuril-Kamchatka depression with a depth of 9717 meters. If we arrange these seas in order of decreasing depth, we get the following: the leader will be the Bering Sea with a maximum depth of 4151 meters. Then comes the Sea of ​​Okhotsk, its depth is 3916 meters. And on last place will be the Sea of ​​Japan, since it, although slightly, is inferior to the Okhotsk Sea, its maximum depth is only 3742 meters. As you can see, the deepest Russian sea - the Bering Sea - is far behind world leaders.

However, this is not all the most interesting things that can be said about the deepest sea in Russia..

Which sea is the deepest in the world?

There is no clear answer to this question, because depth can be assessed in different ways. Usually they still take the maximum depth for comparison, but you can also consider the average depth of the sea. Or the depth of most of the sea. True, no matter how deep the sea is, it still cannot be compared with the ocean depressions. The greatest depth was measured in Mariana Trench- 11022 meters.

It is essentially a deep-sea trench, and the name of the depression is given after the Mariana Islands located nearby. And, since the Mariana Trench is now classified as part of the Philippine Sea, it has become the leader in depth among all the seas on the planet. True, even without this depression, the Philippine Sea is the deepest in the world; the maximum distance to the bottom, according to some sources, is 10,265 meters.

The sea is called large, filled salt water a body of water that must have a connection with one of the five oceans. There are seas wedged deep into the continent, others themselves are divided into several seas, and still others are simply part of the ocean. About 90 seas have formed on Earth, differing in size, shape, depth, and the absence or presence of closed shores.

1. Sargasso Sea (about 6-8 million sq. km)

The largest sea in the world is Sargasso, if only because it has no shores. All other seas have them, but Sargasso - not a centimeter. Its conventional boundaries are considered to be three Atlantic currents. This place is amazing; the conventional dimensions of the sea can fluctuate greatly from year to year; they can be affected by the weather patterns of a given season and the behavior of changeable currents.
In its outline, the Sargasso Sea looks like a light green ellipse. The color is not accidental - it is a continuous thick carpet of sargassum algae, stretching for hundreds of kilometers in any direction, this is a unique phenomenon for the planet. When Columbus passed this sea in search of India, he compared it to a vessel of seaweed. Scientists for a long time They mistakenly thought that these algae were brought from somewhere by the current, but this is not so - they are born here and die here. The depth under them in some places reaches 7 kilometers.
The water here is quite warm throughout the year, its temperature ranges from 18-28 degrees.

2. Philippine Sea (5.726 million sq. km)

This is the name of the oceanic island sea splashing near the Philippine archipelago, which is part of the Pacific Ocean. It is very deep - the average depth is 4108 meters, and the maximum and record on the planet is 10,994 m in the Mariana Trench.
This sea does not have clearly defined shores, and is conditionally separated from the ocean by several groups of islands: from the north - the Japanese archipelago (Ryukyu, Kyushu and Honshu), from the west - the island of Taiwan and the Philippine archipelago, in the east by the islands of Bonin, Izu, Volcano, Marianas islands and underwater ridges, and in the southeast - the islands of Palau and Yap.
The Philippine Sea can be included in several categories: interisland, oceanic, coastal. In the latter category, it becomes the largest coastal sea in the world. This sea is unique not only in its depth and size, but also in the active water exchange between it and open ocean thanks to the currents. And in the sea itself there is active upwelling - vertical movement of water. The powerful northern trade wind current near the island of Taiwan splits into two branches that leave the Philippine Sea. Although the marine fauna here is not very diverse, there is active fishing and whaling here.

3. Coral Sea (4.791 million sq. km)

The Coral Sea is also located in the Pacific Ocean, but it is located between the coast of Australia and the islands of New Guinea and New Caledonia. Its maximum depth reaches 9140 m. This sea received its name due to the fact that in its waters there are many coral reefs and islands, among them: Bampton, Tragross, Willis, Chesterfield. But the most famous in the world is the Great Barrier Reef - the largest coral formation on the planet. After 1969, the Coral Sea came under Australian management. The local islands are uninhabited, only Willis Island has a meteorological station.

4. Arabian Sea (3.862 million sq. km)

This sea separates two huge peninsulas - Hindustan and Arabian, located on the northern edge of the Indian Ocean. This is the largest sea in the basin of this ocean; it flows into famous river Ind.
Inhabited in different periods the shores of this sea the peoples gave him different names: Sindhu Sagar, Eritrean, and the Hellenes called it Persian. Europeans also used them, but, in the end, in the 19th century it was assigned modern name. Surface currents in the Arabian Sea have a seasonal orientation: in summer they are directed east, and in winter they turn towards reverse side. This feature was noticed by Portuguese and Spanish sailors and they used it very skillfully. This is a very warm sea - on the surface the water warms up within 22-27 degrees, occasionally reaching 30 degrees. Thanks to warm climate A very diverse fauna and flora developed in the sea. At depths above 1500 m, water salinity increases to 35%.

5. South China Sea (3.5 million sq. km)

This sea is located on the border of the Pacific and Indian Oceans, refers to semi-enclosed seas. From the northwest it washes the shores of Asia, and on opposite side- islands of Oceania. This is a large and very salty sea - the salt content in it reaches 32-34%. The structure of the seabed is determined by its location. Near the Asian coasts the bottom is lined mainly with sand and silt, and near the coasts of the islands - rocks or Coral reefs. But every winter in the water area of ​​this warm sea cold ones invade air masses from the north, which noticeably cool the surface layer of water. By South China Sea passes through many international trade routes.

On our planet, only 14 mountain peaks have a height of more than 8000 meters. Most of the peaks are located in the Himalayas and are known to everyone under the name "...

6. Weddell Sea (2.8 million sq. km)

This sea is located in the extreme south of the Atlantic Ocean, touching the shores of Antarctica. Its average depth is 3000 m. Every 22-25 years, a huge iceberg breaks off from the ice shelves sliding from Antarctica, which begins its slow migration through the waters of the South Atlantic. Drifting ice in the Weddell Sea is about 2 m thick.
The peculiarities of its location and climate have made the waters of this sea one of the most transparent on the planet. Maximum transparency was noted in 1986, when it reached 79 meters, which is practically not inferior to the transparency of distilled water. The presence of icebergs and compression by ice makes navigation here almost impossible; only occasionally do research vessels come here. Seals and whales live in the sea, and on it rocky shores penguins have settled.

7. Caribbean Sea (2.754 million sq. km)

The marginal Caribbean Sea is partially separated from the Atlantic Ocean by the Lesser and Greater Antilles, and is limited to Central and North America on the west. Man connected it with the Pacific Ocean by breaking the Panama Canal. The Caribbean Sea received its name from the Carib tribe that lived on its shores. It is sometimes also called Antillean. It has been noted that most of the hurricanes that rage in the Caribbean Sea originate western hemisphere. Regular hurricanes constantly destroy the fragile buildings of the inhabitants of the coast and islands.
The Caribbean is amazingly rich animal world both in the water and on the islands. Many species are endemic to the Caribbean region. Up to 9% of all corals in the world's oceans live in this sea.
Centuries ago, the Caribbean Sea was the main theater of war for swashbuckling pirates, beautifully depicted in many films. And now they have been replaced by treasure seekers scattered across islands and sunken ships in the sea. The phenomenon of piracy flourished in the 17th century, and the main bases of pirates, buccaneers and other corsairs were Port Royal and Tortuga Island.

8. Mediterranean Sea (2.5 million sq. km)

This is the main sea in the history of mankind - the cradle modern civilization. From here the Phoenicians and Hellenes began exploring the world. The Mediterranean Sea separates two continents - Africa and Eurasia. It belongs to the Atlantic Ocean, being connected to it by the Strait of Gibraltar, in which ancient greek myths erected the pillars of Hercules. The Hellenes did not dare to go out into the Atlantic, preferring to swim, seeing the shores.
This is the only sea that washes three continents at once: Africa, Europe and Asia. Maximum depth Mediterranean Sea in the central basin is 5121 m. Surprisingly, over thousands of years people have not mapped the exact contours of the Mediterranean Sea; Captain Gautier did this only in late XIX century - after his research, realistic outlines of the sea coast were obtained.

9. Tasman Sea (2.33 million sq. km)

The Tasman Sea is located between Australia, the island of Tasmania and New Zealand, it is part of the Pacific Ocean. Together with the island, the sea was named in honor of Abel Tasman, a Dutch navigator. It was studied extensively by the Englishman James Cook.
This is a very deep sea, especially in the Tasman Basin, where the depth is almost 6 kilometers. Although the sea is quite calm, there are strong tides up to 5 meters high. Another feature of the Tasman Sea is its location in three climatic zones, thanks to which there is a very colorful fauna here. In the northern and southern shores The seas are inhabited by completely different algae, fish and marine animals. The beauty of the coral reefs off the coast of Australia and New Zealand and the diversity of life forms attract many tourists here.

For ordinary person the difference between “dormant” and “extinct” volcanoes is not obvious. But the differences between them are quite significant,...

10. Bering Sea (2.26 million sq. km)

In the North Pacific Ocean, separating Eurasia and North America, is the Bering Sea. The Commander and Aleutian Islands are considered its southern border. In the north, through the Bering Strait, this sea connects with the Chukchi Sea. For Russia this sea is the largest. The maximum depth of the Bering Sea reaches 4151 m. By type, it can be classified as a marginal sea separating the Asian and American continents.
The USSR and the USA could not divide this sea for a long time, only in 1990 they concluded an agreement in which the dividing line was fixed, named after the foreign ministers Shevardnadze and Baker who signed it. Most This sea is covered with ice every year, but this does not prevent over 240 species of marine animals and fish from living in it.
