QUESTION OF NAME OF THE SEA IN South Korea The Sea of ​​Japan is called the "East Sea" (kor.), and in North Korea the East Sea (kor.). The Korean side claims that the name "Sea of ​​Japan" was imposed on the world community by the Japanese Empire. The Japanese side, in turn, shows that the name "Sea of ​​Japan" is found on most maps and is generally accepted.

Flora and fauna Off the coast Far East there is a mixture of warm-water and temperate fauna. Here you can meet octopuses and squids, typical representatives of warm seas. At the same time, vertical walls overgrown with sea anemones, gardens of brown kelp algae, all this resembles the landscapes of Bely and Barents Sea. In the Sea of ​​Japan there is a huge abundance of starfish and sea ​​urchins, of various colors and sizes, there are brittle stars, shrimps, small crabs ( king crabs here they are found only in May, and then they go further into the sea). Bright red sea squirts live on rocks and stones. Of the mollusks, scallops are the most common. Of the fish, blennies are often found, sea ​​ruffs.

ICE CONDITIONS In the Sea of ​​Japan, the ice cover reaches its maximum development in mid-February. On average, 52% of the area of ​​the Tatar Strait and 56% of the Peter the Great Bay are covered with ice. The melting of ice begins in the first half of March. In mid-March, the open waters of Peter the Great Bay and the entire seaside coast to Cape Zolotoy are cleared of ice. The boundary of the ice cover in the Tatar Strait recedes to the northwest, and in the eastern part of the strait, ice is being cleared at this time.

Sea of ​​Japan - the sea is part of the Pacific Ocean, separated from it by the Japanese Islands and Sakhalin Island.

Location: Northeast Asia.
Area: 1062 thousand km².
Volume: 1630 thousand km³.
Maximum depth: 3742 m. Average depth: 1753 m.

The Sea of ​​Japan is connected with other seas and the Pacific Ocean through 4 straits: Korean, Sangar, La Perouse, Nevelskoy.

Korea Strait

Sangar Strait

Strait of La Perouse

Nevelskoy Strait

The Sea of ​​Japan washes the shores of Russia, Japan, the Republic of Korea and North Korea.

The climate of the Sea of ​​Japan is temperate, monsoonal. The northern and western parts of the sea are much colder than the southern and eastern parts. In the coldest months (January-February), the average air temperature in the northern part of the sea is about −20 °C, and in the south about +5 °C. summer monsoon brings warm and humid air with it. average temperature the air of the warmest month (August) in the northern part is about +15 °C, in the southern regions it is about +25 °C. In autumn, the number of typhoons caused by hurricane-force winds increases. The largest waves have a height of 8-10 m, and during typhoons, the maximum waves reach a height of 12 m.

The salinity of the waters of the Sea of ​​Japan is 33.7-34.3%, which is somewhat lower than the salinity of the waters of the World Ocean.

The tides in the Sea of ​​Japan are distinct, to a greater or lesser extent in different regions. The greatest level fluctuations are observed in the extreme northern and extreme southern regions. Seasonal fluctuations in sea level occur simultaneously over the entire surface of the sea, the maximum rise in level is observed in summer.

According to ice conditions, the Sea of ​​Japan can be divided into three areas: the Tatar Strait, the area along the coast of Primorye from Cape Povorotny to Cape Belkin, and Peter the Great Bay. In winter, ice is constantly observed only in the Tatar Strait and Peter the Great Bay, in the rest of the water area, with the exception of closed bays and bays in the northwestern part of the sea, it is not always formed. The coldest region is the Tatar Strait, where winter season more than 90% of all ice observed in the sea is formed and localized. According to long-term data, the duration of the period with ice in Peter the Great Bay is 120 days, and in the Tatar Strait - from 40-80 days in the southern part of the strait, to 140-170 days in its northern part.

Undersea world northern and southern regions of the Sea of ​​Japan is very different. In the cold northern and northwestern regions, flora and fauna of temperate latitudes have formed, and in the southern part of the sea, south of Vladivostok, a warm-water faunistic complex prevails. Off the coast of the Far East, a mixture of warm-water and temperate fauna occurs.

In the Sea of ​​​​Japan you can meet octopuses and squids - typical representatives warm seas. Also, vertical walls covered with anemones, gardens of brown algae - kelp.

Great abundance in the Sea of ​​Japan starfish and sea urchins, different colors and different sizes, shrimps, jellyfish, small crabs. Bright red sea squirts live on rocks and stones. Of the mollusks, scallops are the most common. Of the fish, blennies and sea ruffs are often found.

Presentation on geography Pupils of the 9th grade, Smirnova Olga "Sea of ​​​​Japan"

The Sea of ​​Japan is a sea within the Pacific Ocean, separated from it by the Japanese Islands and Sakhalin Island. It is connected with other seas and the Pacific Ocean through 4 straits: Korean (Tsushima), Sangar (Tsugaru), La Perouse (Soya), Navel (Mamiya). It washes the shores of Russia, Korea, Japan and North Korea. In the south comes a branch warm current Kuroshio. The area is 1062 thousand km². The greatest depth is 3742 m. The northern part of the sea freezes in winter. Fishing; extraction of crabs, trepangs, algae. Main ports: Vladivostok, Nakhodka, Vostochny, Sovetskaya Gavan, Vanino, Aleksandrovsk-Sakhalinsky, Kholmsk, Niigata, Tsuruga, Maizuru, Wonsan, Hyungnam, Chongjin, Busan.

Climate The climate of the Sea of ​​Japan is temperate, monsoonal. The northern and western parts of the sea are much colder than the southern and eastern parts. In the coldest months (January-February), the average air temperature in the northern part of the sea is about -20 ° C, and in the south about +5 ° C. The summer monsoon brings with it warm and humid air. The average air temperature of the warm month(August) in the northern part about +15 °C, in the southern regions about +25 °C. In autumn, the number of typhoons caused by hurricane-force winds increases. The largest waves have a height of 8-10 m, and during typhoons, the maximum waves reach a height of 12 m.

Currents Surface currents form a circulation, which consists of the warm Tsushima Current in the east and the cold Primorsky Current in the west. In winter, the surface water temperature rises from −1-0 °C in the north and northwest to +10-+14 °C in the south and southeast. Spring warming entails a fairly rapid increase in water temperature throughout the sea. In summer, the surface water temperature rises from 18-20 °C in the north to 25-27 °C in the south of the sea. The vertical distribution of temperature is not the same in different seasons in different areas of the sea. Summer in northern regions The temperature of the sea is 18-10 °C in the 10-15 m layer, then it drops sharply to +4 °C at the 50 m horizon and, starting from a depth of 250 m, the temperature remains constant at about +1 °C. In the central and southern parts In the sea, the water temperature decreases rather smoothly with depth and reaches +6 °C at a depth of 200 m, starting from a depth of 250 m, the temperature stays around 0 °C. Currents on the surface of the Sea of ​​Japan

Salinity. The salinity of the water of the Sea of ​​Japan is 33.7-34.3 ‰, which is slightly lower than the salinity of the waters of the World Ocean. Tides. The tides in the Sea of ​​Japan are distinct, to a greater or lesser extent in different regions. The greatest level fluctuations are observed in the extreme northern and extreme southern regions. Seasonal fluctuations in sea level occur simultaneously over the entire surface of the sea, the maximum rise in level is observed in summer.

Ice conditions According to ice conditions, the Sea of ​​Japan can be divided into three areas: the Tatar Strait, the area along the coast of Primorye from Cape Povorotny to Cape Belkin, and Peter the Great Bay. In winter, ice is constantly observed only in the Tatar Strait and Peter the Great Bay, in the rest of the water area, with the exception of closed bays and bays in the northwestern part of the sea, it is not always formed. The coldest region is the Tatar Strait, where more than 90% of all ice observed in the sea is formed and localized in the winter season. According to long-term data, the duration of the period with ice in Peter the Great Bay is 120 days, and in the Tatar Strait - from 40-80 days in the southern part of the strait, to 140-170 days in its northern part. The first appearance of ice occurs at the tops of bays and gulfs, closed from the wind, waves and having a desalinated surface layer. In moderate winters, in Peter the Great Bay, the first ice forms in the second decade of November, and in the Tatar Strait, in the tops of Sovetskaya Gavan, Chekhachev and Nevelskoy Straits, primary ice forms are observed already in early November. Early ice formation in Peter the Great Bay (Amur Bay) occurs in early November, in the Tatar Strait - in the second half of October. Later - at the end of November. In early December, the development of ice cover along the coast of Sakhalin Island is faster than near the mainland coast. Accordingly, in the eastern part of the Tatar Strait at this time there is more ice than in the western part. By the end of December, the amount of ice in the eastern and western parts levels out, and after reaching the parallel of Cape Surkum, the direction of the edge changes: its displacement along the Sakhalin coast slows down, and along the mainland it becomes more active.

In the Sea of ​​Japan, the ice cover reaches its maximum development in mid-February. On average, 52% of the area of ​​the Tatar Strait and 56% of the Peter the Great Bay are covered with ice. The melting of ice begins in the first half of March. In mid-March, the open waters of Peter the Great Bay and the entire seaside coast to Cape Zolotoy are cleared of ice. The boundary of the ice cover in the Tatar Strait recedes to the northwest, and in the eastern part of the strait, ice is clearing at this time. Early clearing of the sea from ice occurs in the second decade of April, later - at the end of May - beginning of June.

Flora and fauna. The underwater world of the northern and southern regions of the Sea of ​​Japan is very different. In the cold northern and northwestern regions, flora and fauna of temperate latitudes have formed, and in the southern part of the sea, south of Vladivostok, a warm-water faunistic complex prevails. Off the coast of the Far East, a mixture of warm-water and temperate fauna occurs. Here you can meet octopuses and squids - typical representatives of warm seas. At the same time, vertical walls covered with sea anemones, gardens of brown algae - kelp - all this resembles the landscapes of the White and Barents Seas.
