The number of seas washing modern Russia has remained numerically the same as it was under the USSR, exactly 13. 12 of them belong to the basins of three oceans (Atlantic, Arctic and Pacific). The Caspian is not directly connected to the World Ocean, only through the Volga-Don Canal
Russia, the largest country on the planet, is surrounded by three oceans - the Atlantic, Pacific, and Arctic. It is connected to them by 12 seas. There is another one, drainless, in no way connected with the World Ocean. So, a total of 13 seas wash Russia. Each of them is of different origin and age. They also differ in relief and depth, as well as in the inhabitants inhabiting the water area.
All 13
Reference ! A sea is a part of the World Basin that is separated by land or elevated terrain. In addition, it differs from the ocean in climate, changes in water due to natural factors, and weather conditions.
Among the seas washing the Russian Federation:
- Caspian, not related to the World;
- Beringovo, Japanese and Okhotsk (Quiet region);
- Azov, Black and Baltic (Atlantic region);
- Barents, White, Kara, East Siberian, Chukchi and Laptev Sea (Northern Arctic region).
Atlantic group
Baltic. Max. depth - 470 m. Russia, Sweden, Finland, Estonia, Latvia, Lithuania, Denmark, Germany, Poland consider it theirs. Located in the north-west of the Russian Federation. Inland. Quite small. The waters are desalted due to precipitation. So the plankton numbers are not growing. Herring, smelt, sprat are among the most popular fish.
Black. Depth - 2,210 m. It washes Russia, Ukraine, Romania, Bulgaria, Turkey, Georgia, Abkhazia. At the southwestern borders of the Russian Federation. So many rivers flow into it that the coastline is pushed back. At shallow depths, freshwater and Mediterranean fish species (pike perch, tuna, ram, anchovy, stingray and bream) are found.
Azovskoe. According to the world classification, it is classified as the smallest - only 13.5 m at the deepest point. It washes Ukraine and Russia. It is even sometimes called the Black Sea Bay. It freezes in winter, but warms up perfectly in summer. There are about 80 species of fish in the water area, many commercially.
Arctic Ocean Group
White. Max. depth – 343 m, located in the north of Russia. As you approach the surface, the water becomes fresher. It is not rich in fish, no more than 50, but there are many valuable commercial varieties.
Barentsevo. Deep - 600 m. The coastline runs through Russian and Norwegian territory. The ice here never melts. Extreme conditions are not an obstacle for a huge amount of plankton; there are at least 100 species of fish, the vast majority of them commercial. The coastline is home to seals, beluga whales, bears, and more than 20 species of birds on the rocks.
Laptev. Max. depth – 3,385 m. Outlying reservoir of Russia. Temperature - no more than +1℃ even in summer. Siberian rivers and melting ice fill it with fresh water. There is no fishing.
Karskoe. Depth – 620 m. It is washed by the Russian Federation. Its surface is almost always covered with ice and does not warm up above 0℃. In the coastal zone it is fresh. And the bounty of flora and fauna can be the envy of the southern seas - an abundance of algae, chinook salmon, flounder, navaga, smelt, trowel, even cetaceans - sei whale and fin whale. Oil and gas have been discovered on its shelves.
Chukotka. At the deepest point - 1,256 m. A marginal reservoir in the north of the country, covered with eternal ice, and at the same time washes Alaska.
East Siberian. Max. depth – 915 m. Ice water – from – 28℃ in winter and up to +2℃ in summer. The fauna is sparse, and there is no diversity of fish species.
Pacific group
Okhotsk. Max. depth – 3,916 m. A semi-enclosed body of water on the south-eastern coast of the Russian Federation. On the other side of the coast of Japan. Rich in delicious varieties: crabs, starfish, mussels, coho salmon, pink salmon and flounder.
Beringovo. The deepest in the country is 4,151 m. The coastline runs in Russia and the States. In the Russian Federation, its length is 13,340 km with many islands. The water surface is under an ice crust, its temperature ranges from -28℃ to +10℃. Even in such conditions, salmon and flounder of various species live.
Japanese. At a depth of 3,742 m. It washes, in addition to Russia, Japan, South Korea, and the DPRK. In the east of the Russian Federation. The aquatic fauna is rich in commercial varieties.
Without connection with the World
The only closed sea is the Caspian. Max. depth – 1025 m. Its waters are in Russia, Azerbaijan, Iran, Turkmenistan and Kazakhstan. It is connected to the World Ocean only by the Volga-Don Canal. They even call it a lake, even though the water in it is salty. More than 100 rivers flow into it, including the Volga.
Reference! A lake is a closed depression in the continental crust that is filled with water. The inland sea is a structural unit of the World Ocean, cutting deeply into the land. The exception is the Caspian. It is a lake, but not part of the World Ocean. But it is called the sea because of its salty water and large size.
What in the world
There is no other state with so much sea water washing its shores. The Russian Federation owns a water area of 8.6 million km2. Try to imagine the size of this wealth. This is larger than the area of all European countries combined.
In addition, it is larger in size than any country, except for such “giants” as Canada, the USA and China:
- The United States of America is washed by the seas: Chukchi, Beaufort and Bering.
- Canada - Labrador, Baffin, Beaufort and Lincoln.
The territory of the Russian Federation is washed by three oceans. All the seas of Russia, the list of which is given in the text of the article, are interesting and special in their own way. All of them are unique and original.
Seas of Russia: list
The largest country on the planet is connected to three oceans through 12 seas, both internal and peripheral. One sea in Russia does not have a direct connection with the World Ocean (except for the connection through it - this is the Caspian Sea, which is drainless.
| Sea | Belonging to the ocean |
| Azovskoe | to the Atlantic Ocean |
| Barentsevo | to the Arctic Ocean |
| Baltic | to the Atlantic Ocean |

Total - 13 seas.
Atlantic seas
The seas from the Atlantic basin beat against the western shores of Russia. In the north it is the Baltic Sea, in the south it is the Azov and Black Sea.
They are united by the following features:
- they are all internal, that is, deeply continental;
- all of them are the final seas of the Atlantic, that is, to the east of them there are either waters of another ocean or land.
The Russian coastline along the Atlantic seas is about 900 km. The Baltic Sea touches the Leningrad and Kaliningrad regions. The Black and Azov seas wash the shores of the Rostov region, Krasnodar region and Crimea.
Seas of the Arctic Ocean
Some seas of Russia (the list is given above) belong to the Arctic Ocean basin. There are six of them: five of them are outlying (Chukotskoye, Karaskoye, Laptev, East Siberian, Barentsevo) and one is internal (Beloye).
Almost all of them are covered with ice all year round. Thanks to the Atlantic Current, the southwest of the Barents Sea. The waters of the Arctic Ocean reach the territory of such Russian regions as the Murmansk region, the Arkhangelsk region, the Yamalo-Nenets Autonomous Okrug, the Taimyr Autonomous Okrug, the Republic of Sakha, and the Chukotka Autonomous Okrug.
Pacific Seas
The list of seas washing the coast of Russia from the east and belonging to the Pacific Ocean is given below:
- Beringovo;
- Japanese;
- Okhotsk.
These seas are adjacent to the territories of the Chukotka Autonomous Okrug, the Magadan Region, the Kamchatka Region, the Khabarovsk Territory, the Sakhalin Region, and the Primorsky Territory.
Warm seas
Half of the Russian seas are covered with ice all year round. There are seas that are partially covered with ice for a certain period of time. The warm seas of Russia, the list of which is given below, do not freeze throughout the year. So, the warm seas of Russia include:
Seas of Russia: list of unique seas
All geographical objects of the Earth are special and interesting in their own way. There are objects that are unique and inimitable. Of course, this is Lake Baikal, the Volga, Kamchatka geysers, the Kuril Islands and much more. The seas of Russia are also exceptional, a list of which is given below. The table shows the characteristics of some Russian seas from the point of view of their uniqueness.
| Sea | Characteristics in terms of uniqueness |
| Azovskoe | It is considered the most inland sea on the planet. Communication with the waters of the World Ocean occurs through four straits and four seas. Having a depth of no more than 13.5 m, it is recognized as the shallowest sea on the planet. |
| Baltic | It is one of the most unsalted seas in the world. Approximately 80% of the world's amber is mined here, which is why the sea was called Amber in ancient times. |
| Barentsevo | This is the westernmost sea of Russia among those located beyond the Arctic Circle. It is considered the cleanest sea of all that washes the shores of Europe. |
| White | The sea, which has a small area, is the second small sea in Russia after the Azov Sea. It washes the lands of the historical and cultural monument of Russia - |
| Beringovo | |
| Japanese | The southernmost, but not the hottest sea in Russia. Of all the seas in Russia, this one has the richest underwater world. |

Russia is the biggest country in the world. It is washed by three oceans. Pacific Ocean, Arctic Ocean and Atlantic Ocean. The seas that wash Russia most of all are in the north of the country. There are seas that are located only near our borders and in our zone of influence. In total, Russia is washed by 13 seas.
The territory of Russia is washed thirteen seas (together with the Caspian Sea-lake), and the total marine area is 7 million square kilometers. All seas belong to the basins of the Pacific, Atlantic and Arctic Oceans, with most of them belonging to the latter.
List of seas that wash the Russian Federation can be viewed below.
Our country, Russia, the largest on planet Earth, is accordingly washed by many seas, belonging to three of the four world oceans. These oceans are the Arctic, Pacific and Atlantic. There are 12 such seas in total and there is one more, closed, Caspian. This means there are 13 seas in total. Here is the complete list:
Russia is washed by thirteen seas of three oceans. The six seas of the Arctic Ocean are Kara, Barents, Laptev, East Siberian, White and Chukotka. Three seas of the Pacific Ocean - Bering, Japanese, Okhotsk. Three seas of the Atlantic Ocean - Baltic, Black, Azov. And another sea-Lake Caspian, it does not belong to any of the oceans.
Russia turns out to be a country washed by the waters of three oceans at once, two of them directly, and the Atlantic Ocean through internal seas.
In the south, these are the Black and Azov Seas, a health resort and the location of resorts. To the north is the Baltic Sea with the Gulf of Finland, where St. Petersburg is located.
From the Arctic Ocean we are washed from left to right by the White, Barents, Kara, Laptev, East Siberian and Chukchi seas. These are six more seas, very cold, but very important for the country’s economy.
From the Pacific Ocean, Russia is washed by the Bering, Okhotsk and Japanese Seas, and the Sea of Okhotsk is essentially an internal sea of Russia.
And finally, the Caspian Sea, which is essentially an endorheic lake, is considered to be a sea.
Total 13 seas.
The waves of thirteen seas splash off the coast of Russia. All of them belong to the oceans: Atlantic, Arctic and Pacific. The largest number of seas is part of the waters of the Arctic Ocean - there are six in total, one of which, the Barents Sea, occupies the largest area compared to other seas of this ocean.
It should be noted that Wikipedia claims that there are a total of 14 (fourteen) seas that wash Russia and one more plus the internal one.
Therefore, it turns out that there are only 15 - fifteen seas.
The country of Russia, the Russian Federation is the largest country on the Eurasian continent. It is washed by 13 seas.

All answers say that Russia is washed by 13 seas, but this is the wrong answer, since Russia is being washed 14 seas. The fact is that all the seas washing Russia are divided into two categories - closed and external, which belong to the oceans. The Caspian Sea is considered closed. And the remaining 13 seas are divided between the Atlantic, Arctic and Pacific oceans:
It turns out that there are only 14 seas that wash Russia.
Despite the large area of Russia, it is washed by only 13 seas, 12 of which belong to three oceans (Pacific, Arctic, Atlantic) and one sea-lake belonging to the internal endorheic basin of Eurasia. The seas are located on four lithospheric plates (Eurasian, North American, Sea of Okhotsk and Amur).
All seas are distinguished by a number of natural characteristics, such as: origin, geological structure, topography and bottom shape, depth of sea basins, temperature, etc.
Seas of the Arctic Ocean
The largest group of seas that wash Russia belongs to the Arctic Ocean. This group includes the seas: Kara, Laptev, East Siberian, Barents, Chukchi and White.
They wash Russia from the north. It is noteworthy that only the White Sea is inland, all other seas are continental-marginal. Between the seas of the Arctic Ocean, the boundaries are marked by islands and archipelagos (Franz Josef Land, Severnaya Zemlya, Novaya Zemlya, Spitsbergen, etc.), and where the border is not clearly visible, it is drawn mentally. The total area of these seas reaches 4.5 million km^2, and the average depth is only 185 meters.
Since all these seas are on the continental shelf, they are all shallow. The deepest sea is the Laptev Sea. Its northern part occupies the edge of the deep-sea Nansen Basin. The depth of the sea in this place reaches 3385 meters. Thanks to this, the average depth of the Laptev Sea reaches 533 meters.
In winter, its temperature ranges from -0.8°C to +1.7°C, and in summer from +0.8°C to +10°C. The second place of honor is occupied by the Barents Sea, the maximum depth of which reaches 600 meters, and the average depth is only 222 meters. The Kara Sea took third place.
Although its maximum depth is greater than the Barents Sea and reaches 620 meters, its average depth barely reaches 111 meters, which is 2 times less than that of the Barents Sea. The last 3 places in depth are occupied by: Beloe (maximum depth - 350 meters, average depth - 67 meters), Chukotskoye (maximum depth - 160 meters, average - 71 meters) and East Siberian (maximum depth - 155 meters, average - 54 meters ) seas.
Pacific Seas
The three seas of the Pacific Ocean, which wash Russia from the east, are the largest and deepest. Their average depth reaches 1354 meters, which is 7 times greater than the average depth of the seas of the Arctic Ocean. This group includes the seas: Bering, Okhotsk and Japan.
These seas are separated from each other by the Kamchatka Peninsula and Sakhalin Island. The eastern part of the Kamchatka Peninsula is washed directly by the waters of the Pacific Ocean. It can also be noted that these seas are the boundary between the largest continent and the ocean of the planet.
The deepest sea of the entire group is the Bering Sea. Its maximum depth reaches 4151 meters, and the average depth is 1640 meters. In winter, its temperature ranges from -1.5°C to +3°C, and in summer - from +4°C to +11°C. This sea is mixed, continental-marginal type.
The Sea of Japan is in the middle, with a maximum depth of 3699 meters and an average depth of 1535 meters. In winter, the temperature of this sea ranges from 0 to +4°C, in summer - from +18 to +25°C. In last place is the Sea of Okhotsk. Its maximum depth is 3521 meters, and the average is only 821 meters. In winter its temperature ranges from -1.5 to +1.8°C, and in summer 6-7°C.
Seas of the Atlantic Ocean
This group includes three seas: the Black, Baltic and Azov. They reach deep into the continent and wash small areas of it, and their connection with the ocean passes through numerous straits. All these seas are inland.
The Black Sea is the warmest of the seas washing the shores of our Motherland. Its temperature in winter is from 0 to 7°C, and in summer 25-26°C, its maximum depth reaches 2210 meters, and the average depth is 1315 meters. It lies in a tectonic depression, which is bordered by the continental slope. Communication with the ocean is through the seas: Marmara, Aegean, Mediterranean and the straits: Bosphorus, Dardanelles, Gibraltar.
The Baltic Sea is the westernmost of the seas bordering Russia. Its maximum depth is very small and reaches only 470 meters, and its average depth is 51 meters. In winter, its temperature fluctuates around -1°C, and in summer - from +17 to +17°C. The Baltic Sea is located in a tectonic trough at the junction of the Baltic shield with the Russian plate. It is connected to the Atlantic Ocean through the shallow Danish Straits and the North Sea.
The Sea of Azov is the smallest and shallowest sea on the planet. Its maximum depth is only 13 meters, and the average is 7 meters. An inland shelf sea, the connection with the ocean is carried out through the Black Sea, into which it flows through the shallow Kerch Strait. Its depth increases slowly and smoothly as it moves away from the coast. In winter, the temperature fluctuates around 0°C, and in summer it reaches +23-24°C.
Caspian sea-lake
A sea that has repeatedly lost and restored its connection with the World Ocean. The most recent transformation of the Caspian Sea ended with the fact that, as a result of uplifts in the area of the Kuma-Mychin depression, it was finally isolated and became completely part of the drainless Eurasian basin.
Its area reaches 371 thousand km^2, and its depth reaches 1025 meters. At the moment, the Caspian Sea is the largest closed sea. Sea temperature in winter ranges from 0 to +10°C, and in summer - +24 - +28°C. Its hydrological regime and organic world depend on nature and its changes within the sea basin itself, in particular the Volga basin, located entirely within our Motherland.
