The World Ocean is the most amazing and least studied object on our planet. How many mysteries it contains, and how many discoveries are yet 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 contains four of the six deepest seas in the world. If you line up the seas by depth, as by height, in meters and kilometers, then their leaders are: the Philippine Sea and the Coral Sea, then comes the Banda Sea, the Caribbean Sea, the Weddell Sea and the Tasman Sea.


In the 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, the Mariana Trench, is attributed, 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. Due to the enormous depth, marine life here has not been 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 dangerous to humans, including tiger and gray sharks. But the large deep-sea inhabitants of the Mariana Trench are definitely predators, and what kind! 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 there is complete darkness at the bottom of the depression. But many have very developed organs that capture sounds. There are also simple organisms 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 - starfish, hedgehogs and turtles, flying fish, many different types of shrimps, crustaceans and crabs.

The 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. Dolphins, squids, jellyfish, octopuses, nautiluses, sharks, rays, and even sea snakes live in this sea.


In fourth place in the ranking of the depths of the Caribbean Sea. 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 treasures 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 is in first place - its greatest depth is 2258 meters. Compared to the Sea of ​​Azov, which is only about 14 meters deep, or the Baltic Sea (500 meters deepest), the Black Sea is very deep. And it also differs from other seas of 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 slope of the bottom 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 many seas wash its shores, but most of them are in the North and East of the country. But the seas of the Arctic Ocean do not have such depth and dimensions 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 the east of Russia: the Sea of ​​Japan, the Sea of ​​Okhotsk, and the northernmost of them, the Bering Sea. They are separated from the ocean itself by islands (Kuril, Japanese and Aleutian).


Further there are oceanic 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, then 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 a little, is inferior to the Sea of ​​\u200b\u200bOkhotsk, its maximum depth is already only 3742 meters. As you can see, the deepest Russian sea - the Bering Sea - is far behind the world leaders.


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

Which sea is the deepest in the world?

There is no single answer to this question, because depth can be assessed in different ways. Usually, nevertheless, they 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 oceanic depressions. The greatest depth was measured in the Mariana Trench - 11022 meters.


It is essentially a deep-water trench, and the name of the depression is given by the nearby Mariana Islands. And, since the Mariana Trench is now assigned to 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 of it, according to some sources, is 10265 meters.

In total, there are 63 seas on Earth that are part of the oceans.

The deepest sea on earth is Philippine Sea, the Mariana Trench located in it, set a record for the depth of the World Ocean - 11022 meters. This sea, in particular the Mariana Trench, attracts the attention of researchers from all over the world, but the high cost of scientific work and the need for sophisticated technical equipment become an obstacle for the vast majority of scientists.

coral sea , is one of the deepest seas of the World Ocean, being part of the Pacific Ocean. It is located off the coast of Australia and New Guinea, its depth is 9140 meters.

The attraction of the Coral Sea is the Great Barrier Reef, familiar to almost all the inhabitants of the planet.

caribbean sea with a maximum depth of 7686 meters, is another deep-sea world record holder. Located in the Atlantic Ocean, the sea has gained international fame due to the historical processes associated with the development of medieval piracy in this region. Glorified by numerous novels and films, these fearless adventurers brought not only popularity to the Caribbean, but also global exploration, which was combined with an endless search for fabulous treasures, inextricably linked with pirate legends.

The next record holder in depth - sea ​​gang , also related to the Pacific Ocean. Its greatest depth is 7440 meters. Located between the islands of the Malay Archipelago, the sea has many unexplored areas, which, of course, cannot be compared with the Mariana Trench in their depths, but may well allow them to take third place in the ranking of the deepest seas in the world.

The study of the depths of this sea has been going on for 17 years and is carried out by various international organizations, while bringing constant new results of deep measurements.

Max Depth Arabian Sea is 5803 meters. The sea is located in the Indian Ocean and is limited to the Arabian Peninsula. This region has a rich history and modern economic potential.

6th place

tasman sea , located in the southwestern Pacific Ocean, has a depth of 5200 meters. The sea is the border separating New Zealand and Australia. The study of this water body began in 1770 by the famous navigator and traveler James Cook. He carried out detailed descriptions and measurements of the depths of the Tasman Sea on his first round-the-world expedition.

Beaufort Sea , located in the Arctic Ocean, its maximum depth reaches 4683 meters. Rich oil deposits have become the reason for the study of the sea depths of this water body.

The US authorities are actively sponsoring geological exploration in this region, scientists believe that the sea has a double bottom, under which are hidden vast deposits of various minerals, not only hydrocarbons, but also precious metals.

bay of bengal, which is part of the Indian Ocean, in some of its sections reaches a depth of 4694 meters. Washing the shores of four states, the bay has the longest beach in the world, the length of which exceeds 120 kilometers. Also, the Bay of Bengal is the largest in the world, its area is more than 2.1 million km 2. Due to its hydrochemical and hydrological characteristics, it is an officially recognized sea by the International Hydrographic Organization.

Seas are amazing objects on our planet. Their expanses are little studied, but even the available data is enough to admire the depths, latitudes and the underwater world. It is difficult to say unequivocally how many amazing treasures have been lost at the bottom of the seas, how many amazing discoveries have not yet been made by scientists, how many secrets are stored in the sources of the diverse underwater and plant world. However, we can build on the available data to rank the deepest seas, respectively, the most interesting and mysterious places on Earth.

Rating of the deepest seas of our planet

2258 meters

The deepest among the inland seas of Russia is the Black Sea. It makes no sense to say that at some points it is likely that there are more serious indicators, you yourself understand this. But at present, a record equal to 2258 meters has been registered. By the way, the record depth of the Sea of ​​Azov is only 14-16 meters. Baltiyskoye boasts a mark of 500 meters. This is for you to compare. But the Black Sea is not the largest and most amazing in Russia. Although a few facts really make him admire. It is home to the most expensive fish containing black caviar.

Continuing the theme of Russia, it should be noted that the eastern shores of the largest ocean have 3 large seas at once:

  1. Beringovo;
  2. Okhotsk;
  3. Japanese.

Among the names presented, the most famous is, of course, the Bering Sea. It is the deepest in the territory of the Russian Federation. The depth is 4151 meters. The second place is occupied by Okhotsk, the maximum depth of which is 3742 meters. The maximum depression of the Sea of ​​Japan is 3044 meters. It is likely that other results will be found over time. By the way, you may be interested to get acquainted with the deepest depressions of our planet. In the meantime, we continue the current topic, and proceed to review the giants of the entire planet, and not just the Russian Federation.

7090 meters


Despite the relatively small size, we are talking about a very deep sea located in the Atlantic Ocean. To be precise between Central and South America. The maximum recorded depth to date is 7090 meters. At the same time, many frigates and galleons are observed in the Caribbean Sea. Consequently, there are a huge number of such invariances, however, as well as ups and downs. This place is a favorite among pirates and adventurers. A huge number of people annually try to discover the treasures that an amazing reservoir undoubtedly keeps in its depths.


The third place in the ranking of the deepest on the planet belongs to the Banda Sea. The depth is 7440 meters. A unique spring of a rich underwater world is located off the coast of Indonesia. Another sea that is part of the Pacific Ocean. We are talking about a volcanic zone, as well as an island of volcanic origin. Speaking about the underwater world, the following inhabitants should be distinguished:

  1. rare dolphins;
  2. jellyfish;
  3. various nautiluses;
  4. sea ​​octopuses;
  5. squids;
  6. large stingrays and amazing sea snakes.

Naturally, the most unique species live at the very bottom.


The second line in the ranking of the deepest is the Coral Sea, also located in the Pacific Ocean. Most of the Philippine archipelago. At the same time, experts believe that it is the Coral Trench that belongs to the deepest oceanic trench, it is called the Mariana Trench. Below we will talk about it in more detail. As for the depth of the Coral Sea, it exceeds the mark of 4 kilometers. Unfortunately, it is quite difficult to accurately name the maximum mark, because the above value is observed in many zones.


The deepest sea on the planet- Philippine, and its depth is 9140 meters. That is twice as much as the closest competitors. It is also located in the Pacific Ocean, from which we can draw a reasonable conclusion - in the Pacific Ocean there are the deepest marine reservoirs. The greatest coverage is observed in Australia and off the coast of New Guinea. For this sea, a characteristic difference is the presence of many islands, the largest of which is a large and at the same time unique barrier reef. In the water there is a huge number of crabs, crayfish, flying fish. The unique inhabitants also include starfish, urchins and turtles.


As promised, we can say that the deepest place is the Mariana Trench, of all recorded today, of course. It is a kind of trough assigned to the territory of the Philippine Sea. It is the leader because the depth is 10265 meters. However, even without this unique place, the Philippine is the deepest.
Thus, we examined the most unique seas of Russia and the world as a whole. The conclusion is this: the deepest places in the Pacific Ocean, while on the territory of the Russian Federation the Bering Sea is deeper than the rest!

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 mankind. But this is only a grain in the study of 71% of the planet's territory, which is occupied by water.

At the moment, you can know exactly how many seas there are in the world, which of them are the largest, and which 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. Here you definitely wouldn’t want to get lost or stay hanging out in the boat after the crash. It is said that one of the largest ship cemeteries is located in the Sargasso Sea. Swimming away from this reservoir is not entirely easy, 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. According to rough estimates of scientists, their number is estimated at 4-11 million tons. That is why a lot of animals live in this reservoir.

The Sargasso Sea is located at an impressive distance from the nearest shores of the sinister volcanic Bermuda Islands (triangle). For recreation, it is better to choose another reservoir, because here, under the algae constantly floating on the surface, an incredible danger lurks - powerful underwater eddies formed by different currents. Given the maximum depth of 6995 m, it is scary to imagine where one of these funnels can drag. They bizarrely affect the temperature of the water: in one place it can be +18 ° C, and in the other - +28 ° C. An additional horror is the phenomenal level of the Sargasso Sea, which is much higher than the surrounding waters.

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

The Philippine Sea - Deep and Unexplored


This body of water is completely dominated by the Pacific Ocean. If you suddenly want to independently check 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 borders, 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 primarily known as the deepest sea on Earth, as it is here that the ominous Mariana Trench is located at 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 trough is part of the territory of the Philippine Sea; rather, it is located in the Pacific Ocean. In addition to the impressive depth in this reservoir, there is an anomalous zone with increased seismic activity. Because most earthquakes occur here.

Coral Sea - extraordinary


This body of water is known primarily not because of its impressive area of ​​4791 thousand km² or a maximum depth of 9140 m. This body of water is famous for its outstanding Great Barrier Reef - the largest coral reef in the world. However, it is threatened by pollution (from the Australian population) and a gradual decline in fish fauna (from poachers breaking off reefs for sale, and Crown of Thorns starfish eating masses of reef-building coral polyps).

The territory of the Coral Sea belongs to Australia and the Pacific Ocean. Also in the neighborhood are New Guinea and New Caledonia. A lot of islands are scattered over the entire area of ​​\u200b\u200bthe reservoir, which are mostly not inhabited, only on Willis Island there is a lone meteorological station.

The Bering Sea is the largest in Russia

Its area is 2315 thousand km², and the maximum depth is 4151 m. It is interesting that the reservoir is located in three climatic zones at once - subarctic, arctic, temperate. Violent winds often walk here, creating incredible storms and waves up to 10 m in height.

The Red Sea is beautiful and clean


No matter how charming 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 lead his flock.

The Red Sea is the champion 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 is able to recover at an incredible rate. The Suez Canal does not harm her in any way. 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 are talking about depth, then the Sea of ​​\u200b\u200bAzov is considered the shallowest, with a maximum depth of 14 m. And if we talk about the area, then the Sea of ​​\u200b\u200bMarmara is considered the smallest. Its area is only 11 thousand km², but the depth is more impressive - 1355 m. It is interesting that this reservoir serves as a link between Europe and Asia, connecting the continents with a one and a half kilometer bridge.

What is the deepest sea in the world? After all, on Earth there are a huge variety of different seas. But the deepest sea in the world is the Coral Sea. This is the Pacific Ocean, which is located between the coasts of several countries - New Caledonia, Australia and New Guinea. The total area of ​​the deepest sea on Earth is 4,068 thousand square kilometers. The deepest place in the sea is 9,174 meters, and the average volume of its water is 11,470 thousand cubic kilometers.

The deepest and clearest sea gets its name from the abundance of coral reefs and islands that make navigation difficult. In this sea there are such islands as Tregross, Chesterfield, Willis, Bampton. The most famous reef, which is located in the deepest sea on the planet, is the Great Barrier Reef. This reef is considered the largest reef in the world. It is worth noting that the islands listed above are not inhabited. There is a meteorological station on Willis Island.


The bottom of the deepest sea on earth is heavily dissected. Currents are capable of forming a cyclonic circulation. The temperature of the water of the deepest sea in the south reaches 19 degrees Celsius, and in summer it warms up to 24 degrees. The salinity of the sea is estimated at 34.5-35.5%. There are a large number of sharks and flying fish in the sea. Since 1969, the territory of the deepest sea in the world has belonged to Australia and belongs to Canberra. In 1942, a naval battle took place on this sea between the Japanese and Allied naval forces. This battle prevented the capture of Port Moresby by Japan. The main ports of the sea are: Port Moresby (New Guinea), Cairns (Australia) and Noumea (New Caledonia).

But Russia is washed by as many as 12 seas. But which sea is considered the deepest? The deepest sea in Russia is the Bering Sea. The sea was named after Vitus Bering, who was the first to explore this reservoir. Prior to this, the sea was given such names as Kamchatskoe, Beaver, but still Bering got accustomed. The deepest sea in Russia is located in the northern part of the country and, like the previous deepest sea in the world, belongs to the Pacific Ocean. It is in this sea that a section of the border between Russia and the United States passes.

The deepest sea in Russia is large. Its area is 2,315 thousand square kilometers. But the main feature of the sea is its depth. The deepest place in the sea has a depth of 4,151 meters, while the average depth of the sea is 1,612 meters. It is worth noting that the Bering Sea did not even make it into the top ten deepest seas in the world. It is worth noting that the Black Sea is also included in the list of the deepest seas in the world. The deepest point of the Black Sea reaches 2,000 meters. And the officially registered deepest place in the Black Sea is a depth of 2,211 meters. The deepest depression in the sea is the Yalta depression.

The list of the deepest seas in the world includes the Caspian Sea. The deepest point of the Caspian Sea reaches 1000 meters. The deepest seas of Russia, Wikipedia gives 12 names. Among the deepest seas washing Russia there are the Bering Sea, the Laptev Sea, the Baltic Sea and others.
