Man has always been interested in the seas; he was irresistibly drawn and fascinated by their wild, unbridled beauty. On modern stage there are ninety of them in the world. It is interesting to know what is the largest sea on Earth and the deepest, what is it called and where is it located. Let's take a closer look at the amazing places on the planet.

What is the sea?

This is a certain area in the World Ocean, which is isolated by land or underwater elevations. It differs markedly in climatic, meteorological and hydrological properties. There is a certain classification of seas according to the degree of their isolation:

• outlying;
• internal;
• interisland;

From a geological point of view, even the largest sea in the world is very young education. They took their final form in the Anthropocene. The deepest ones were formed in places where the earth's crust was broken, and the shallow ones are the result of the flooding of the continent by the waters of the World Ocean.

The Sargasso Sea is a unique place on the planet

It is unlike any other. This is the largest sea in the world. It is a special area in the Atlantic Ocean, which is limited by currents, including the Gulf Stream, and not by continents and underwater hills. Its area covers about 7 million km 2, and most of it is covered with algae, which gave it its name - sargassum (sea grapes). Their large thickets create an obstacle in the path of ships and have long been the subject of many legends and fictions. The warm waters of the Sargasso Sea are home to large quantity species of amazing creatures, such as the clown fish. Many fish specifically come there to spawn, since there is no threat from large predators. The sea is unique and stands apart from the rest.

The largest and deepest sea

Its area is almost 6000 square meters. km, and the maximum depth reaches 11022 m. This is the Philippine Sea, located in the western part of the Pacific waters. It does not have smooth and clear boundaries on land, and is separated from the ocean by groups of islands. This is the second largest sea after the Sargasso, but the first in depth. Some researchers attribute the famous Mariana Trench to its territory, but officially it still belongs to the Pacific Ocean. Fishing and whaling are active in the waters of the Philippine Sea.

Largest sea by area: top 5

If we do not take into account the already mentioned Sargasso and Philippine Seas, the rating will look as follows.

Seas on Russian territory

The territory of the country is washed by the waters of thirteen seas, which belong to three oceans. They are not so big and not so warm compared to the world giants.

• Atlantic Ocean: Baltic, Azov and Black Seas. The latter is the warmest of all, with an average summer water temperature of 23-25°C.
• Arctic Ocean: Chukchi, Barents, Pechora, East Siberian, Kara, White and Laptev Sea.
• Pacific Ocean: Japan, Bering and Okhotsk Seas.

The largest and deepest sea in Russia is the Bering Sea (pictured above), located in the Pacific Ocean. It is very cold and even in summer the water temperature in it fluctuates between 7-10 °C. However, it is very rich in commercial fish species and shellfish. The main mammals are representatives of pinnipeds, seals and bearded seals, walruses, seals - the latter form large rookeries on the shores of Chukotka. The Bering Sea is also home to whales, including blue whales, bowheads and humpback whales.

Having learned about the largest sea in the world, do not forget about the smallest sea on Earth - Marmara. It got its name from the nearby island of Marmara, where white marble was once mined, a place known since the times of Ancient Greek civilization. Located in the Atlantic Ocean between Asia Minor and European part Turkey. Its area is only 11,472 square meters. km. The waters of the Sea of ​​Marmara are very salty and warm, so the shores are densely populated.

The oceans can be called a unique object on planet Earth. It conceals thousands of mysteries and surprises with the diversity of the underwater world. The World Ocean consists of a large number of oceans and seas, which differ in depth, size, flora and fauna. Among this diversity, scientists identify several of the most deep seas World ocean.

It is recognized as the largest in size and deepest. It occupies 5726 thousand square kilometers. Since the deepest depression on earth belongs to the sea, its maximum depth is 11022 m. It is in this place that the Mariinskaya Trench was formed. The average depth of sea waters is 4108 m.

The sea is located near the Philippine archipelago and is an oceanic interisland sea in the Pacific Ocean, from which it is separated by numerous islands. The sea has no clear boundaries. There are volcanoes at its bottom. But there is little data on the marine life that is found in the waters of this sea. It's because of the great depth. Therefore, scientists were able to study mainly the inhabitants of coastal zones and surface waters.

Among the fauna in the Philippine Sea there are dolphins, sea ​​turtles, inhabited by swordfish and numerous shellfish. There are many sharks in the waters of the deepest sea, including gray and tiger sharks.

The second deepest sea is located in the Pacific Ocean - Coral. It has a semi-closed shape off the coast of Australia and New Guinea. The maximum depth is 9174 m. The water area is 4068 thousand square kilometers. The sea has many coral reefs and is recognized today as the most beautiful in the world.

For many years, scientists believed that there was no life at such great depths. But thanks to development modern technologies managed to get as deep as possible while studying the World Ocean and learned that even at the depths of the sea, life is simply in full swing. True, it is not yet possible to thoroughly study the fauna and flora of the Coral Sea.

The following types of marine life are known to inhabit the sea:

• dolphins;
• squid;
• flying fish;
• sea ​​stars;
• sea ​​urchins;
• sea ​​turtles;
• shrimps;
• jellyfish;
• crabs.

In the waters of the Coral Sea, scientists sometimes encounter very amazing creatures, which only fuel the belief in legends about sea monsters.

Banda is inferior to the Coral Sea by almost 2 km. Its depth is 7440 meters at its deepest point and is located in the Weber Trench. At the same time, the sea cannot boast of its enormous size - its area is only 714 thousand km².

Since this zone is volcanic, all the islands located in the Banda Sea are of volcanic origin. Sea waters wash the shores of Indonesia. Banda seawater is home to interesting representatives of marine fauna, including octopuses and jellyfish, dolphins, stingrays, sea snakes, nautiluses and sharks.

In the Atlantic Ocean somewhere in the middle of the Central and South America one of the most legendary seas is located. It is ranked fourth in the ranking of deep seas, since at its maximum point its depth is 7090 m. And its area is 2777 thousand square meters. km.

The Caribbean Sea has a reputation for pirates and this is no coincidence. At the bottom you can see many sunken ships that date back to different eras. The search for ancient treasures is still ongoing between the depressions, the rights to which are disputed by many different countries.

The not-so-well-known Weddell Sea occupies an honorable fifth position. Its depth reaches 6820 meters, which is quite a bit less than that of the Caribbean Sea.

The sea is located near the coast of Antarctica, so most of the time its waters are covered with a thick layer of ice. In some places the ice is about 2 meters thick. But, despite the frozen state of the upper part of the waters of the Weddell Sea, life is bubbling under the snow cover. Popular representatives of the cold continent are whales and seals.

The Tasman Sea is located off the coast of Tasmania and also washes the shores of New Zealand. This is another sea that belongs to the water area Pacific Ocean. It lags quite a bit behind the Weddell Sea in terms of maximum depth. It is 6015 m. And the area of ​​sea waters is 3336 thousand square meters. km.

The flora and fauna of the sea waters of the Tasman Sea is very diverse, since its location falls on three climatic zones:

1. In the northern part the vegetation and animal world very reminiscent of the flora and fauna of the Coral Sea. Meet Coral reefs. There are also many species of sharks in the Tasman Sea.
2. In the southern part of the sea, the vegetation is richer, but the species diversity of fish is moderate. But more often you can see large schools of fish.

The Mediterranean Sea also belongs to the deep seas. This is an intercontinental sea, which is located between Asia, Europe and Africa. At its deepest point it reaches 5267 m, and its area is 2.5 million km. square. Since the coastline is indented, the sea is divided into many water areas. Today they have their own names, which have stuck since ancient times.

Undersea world Mediterranean Sea very diverse due to the large area of ​​water and different climatic conditions in its various parts. The waters are usually calm due to the comfortable climate on the coast, but there are also storms when the wind brings bad weather.

Deep seas in Russia

On the vast territory of the Russian Federation there are no seas that occupy leading places in the ranking. But the deepest sea in the country is called the Bering Sea.

Its maximum depth is 4151 meters. We can make a small comparison:

• Sea of ​​Azov - 14 meters.
• Baltic Sea - depth 500 meters.
• The Black Sea has a depth of 2258 meters.

In second place is the Sea of ​​Okhotsk with a maximum depression of up to 3742. And in the next position is the Sea of ​​Japan - 3044 meters. Of the inland seas of the Russian Federation, the Black Sea is recognized as the deepest.

Research of the seas and oceans is ongoing. And, perhaps, scientists will soon discover new depressions, which will affect the change in the rating of deep seas. But be that as it may, the World Ocean is still full of surprises and incredible discoveries. No one knows how many more secrets its blue waters conceal!

The saltiest sea in the world

The Dead Sea is definitely salty (salinity is 300-350%). Only it cannot be called a full-fledged sea entering the world ocean. It's a lake after all. As for the saltiest sea, it is, not surprisingly, red. The salt concentration here is 41%. A liter of sea water contains 41 grams of salt, in simple terms.

Most of the salt in the Red Sea is found at depth, but the closer to the surface, the less salty the water. By the way, the Red Sea has problems with water as such. It is located in a region with a continental tropical climate. Therefore, the probability of precipitation here is extremely low throughout the year. Every year the sea loses about 2000 mm of water, and precipitation restores only 50-100 mm. But the water level is not falling. All because of the Gulf of Aden, connected to the sea by the Bab el-Mandeb Strait.

The largest sea in the world

Surprisingly, the Mediterranean Sea is not the largest in the world. This is the Sargasso Sea, which many have not even heard of. This is because it has no coastline, it is a boundless sea. Essentially, the Sargasso Sea (named after the Sargassum-type algae) is a large piece of still water in the Atlantic Ocean that is bounded on all sides by currents. The exact dimensions of the largest sea in the world are unknown to anyone, but it is assumed that it is 6-7 million square kilometers of water.

The second largest sea on earth is the Philippine Sea. Third place behind the Coral Sea.

The deepest sea in the world

By the way, the Philippine Sea is also the deepest. The maximum depth is 10,540 meters, more than 10 kilometers! This place is called the Challenger Deep. It is located in the famous Mariana Trench on the eastern border of the Philippine Sea.

The second deepest sea is the Coral Sea, which is located in Australia and also washes New Guinea and New Caledonia. The depth is 9140 meters.

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 arrange the seas by depth, as 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 the average depth of 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 are not fully studied, mainly those that are found in surface and coastal waters. It is known that sea turtles, dolphins, swordfish, and various shellfish live in the Philippine Sea. In addition, there are a lot of sharks that are dangerous to humans, including tiger and gray sharks. 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 all deep-sea fish have eyes, and if they do, they are not at all like the ones we are used to, 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 are starfish, urchins and turtles, flying fish, many 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 the 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 the inland seas of our country it ranks first - its greatest depth is 2258 meters. Compared to the Sea of ​​Azov, whose depth is only about 14 meters, or the Baltic (500 meters is the longest 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 (Caucasus, South coast 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 the seas of the Arctic Ocean do not have the same 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 in 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 the Mariana Trench - 11,022 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.

There are 90 seas in total on Earth. At the same time, the largest sea in the world is significantly different from all others. All of them are located inside the continents, and Sargasso is a separate part of the ocean. However, its uniqueness lies not only in this.

The value ranges from 6 to 7,000,000 km2. In second place is Philippine, its size is 5,276,000 km2. In third position is the sea in the Indian Ocean: the Arabian, with an area of ​​4,862,000 km2.

The largest seas of the Pacific Ocean share fourth and fifth place in the ranking. These are Coral - 4,791,000 km2 and Tasmanovo - 3,336,000 km2. The Wedell Reservoir is in sixth place, its area is 2,920,000 km2. Another representative from the Atlantic Ocean is the Caribbean - 2,754,000 km2, occupying seventh position. The area of ​​the Mediterranean, which is in eighth place in the ranking, is 2,500,000 km2.

The largest sea in Russia- Beringovo with an area of ​​2,315,000 km2, Okhotsk completes the ranking of ten giants, its area is 1,603,000 km2.

From everything that has been said previously, in response to the question: which sea is the largest in area, we can give the corresponding list:

1. Sargasso;
2. Philippine;
3. Arabian;
4. Coral;
5. Tasmanovo;
6. Wedell;
7. Caribbean;
8. Mediterranean;
9. Beringovo;
10. Okhotsk.

Attention! The waters of the Bering Reservoir are covered with ice almost all year round!

Depth and location

The Pacific Basin includes deepest sea in the world- Filipino. It is here that the largest depression on planet Earth is located - its depth is 11,035 m. The second place is occupied by the largest sea in the Pacific Ocean - the Coral Sea, its depth at the lowest point is 9,174 m. It is recognized as the most beautiful due to the large number of coral reefs.

The largest sea, located in the Indian Ocean, has a depth of 5,800 m. The area of ​​the Arabian Sea is larger than the Wedell reservoir, but the latter is more than 1 km deeper, and the largest point is located at a depth of 6,820 m. Interestingly, the depths prevail in the northern parts, southern mostly no more than 500 m.

The depth of the Philippine Sea is almost 2 times greater than the others. Conclusion: The Sargasso Sea is the largest, but not the deepest.

The maximum depth of the Tasman Sea, located between Australia and New Zealand, is 5,200 m, the so-called Australian Basin. Another body of water in the Atlantic Ocean, the Caribbean, is located in the semiring formed by South and Central America. 7687 m is the maximum depth of this abyss, the average is only 1,200. Because of this, the reservoir is considered shallow. What is the maximum depth of the Mediterranean Sea, which washes the coasts of more than 10 European countries? Total 5,121 m.

Attention Despite the intercontinental location of the Mediterranean Sea, it belongs to the basin of the Atlantic Ocean, connected to it by the Strait of Gibraltar.

Philippine Sea

Short description

To more than 90 seas, differing from each other in shape, size, depth, presence or absence of banks. Each of them is individual in its own way: one is the shallowest, the other is the deepest, the third is the largest, the fourth is the smallest. One of them does not have clear boundaries at all.

Sargasso

The Sargasso Sea of ​​the Atlantic Ocean is the only one bankless, it is located between the 23rd and 35th parallel northern latitude, 62 and 78 meridian of western longitude. It is surrounded on all sides by currents, in the west by the Gulf Stream, in the south by the North Trade Wind, in the east by the Canary Wind, and in the north by the North Atlantic.

Clockwise rotating streams of water separate the largest body of water in the Atlantic Ocean basin, forming a so-called backwater with a motionless surface. The temperature in the summer season is 27 - 30 ⁰С, and in the winter - 19 - 24. The largest sea in the world has a number of mysterious phenomena, for which no explanation has yet been found:

• It's always calm here;
• mirages, simultaneous sunrise and sunset, are common;
• repeated crashes of small planes are explained by suction circular movements of air;
• the beginning and end of the storm occurs instantly;
• The Sargasso Sea of ​​the Atlantic Ocean is a zone of active seismic activity;
• the largest sea in the world negatively affects people: some become lethargic, others panic or experience inexplicable horror.

The Sargasso Sea of ​​the Atlantic Ocean is a dangerous zone, namely The famous Bermuda Triangle is located here. Its approximate angles are near Florida, Bermuda and Puerto Rico. The site occupies about 1,000,000 km2 of water space, which accounts for most of the missing aircraft and sunken ships.

Attention! There are many versions explaining the strange properties of the Bermuda Triangle, the main one being the excessive content of hydrogen sulfide and methane in sea water.

Mediterranean

As mentioned earlier, the greatest depth of the Mediterranean is 5,121 m; for this sea, the average depth is only 1,521 m. It divides 3: Africa, Europe and Asia. If we count the states whose shores it washes, the list will contain 21 countries. The area is interesting and attractive for tourists, as many architectural monuments are concentrated on the coast. The Mediterranean basin includes 11 reservoirs, among which 2 wash the shores of Russia:

• Black;
• Azovskoe.

Philippine and Arabian

Few people know which sea is the largest in the Indian Ocean by area. It is Philippine, located between the Japanese, Philippine Islands and the island of Taiwan. Favorable climate and high water temperature on the surface, make it the region's leader in whaling and fishing.

The entire area of ​​the Arabian Sea is sheltered from strong winds and cold currents by the Hindustan and Arabian peninsulas. The average water temperature on the beaches is not lower than 20 - 22⁰С, which makes the reservoir a popular tourist destination.

Arabian Sea

Seas of Russia

It is known that the Bering Sea the largest in Russia, its waters are part of the Pacific Ocean, and its features geographical location not inferior to the Mediterranean. Here lies the border between Eurasia and North America and 3 climatic zones. Opens from ice for no more than 3 months. The rest of the time it is covered with a thick layer on which you can drive a car.

The second deepest and largest sea in Russia is the Okhotsk Sea. It belongs partly to the Russian Federation and Japan. The Kuril Islands located in it still serve as a source of disputes between countries. Exactly it is considered the coldest among Far Eastern reservoirs.

Comparing what is the greatest and average depth in the Black Sea of ​​the Atlantic basin, the difference will be insignificant: only 2,210 m versus 1,150. Its waters wash the coasts of 7 countries called “Black Sea” countries. The waters in the Black Sea are saturated with hydrogen sulfide, therefore there is no life at a depth of more than 220 m.

Oceans covering 71% of the Earth's surface.
