Donghai, Namhae, Dong Hai, Pinyin - this area of the Pacific Ocean has many names. On its shores, three ancient civilizations of mankind were born and reached their peak: Chinese, Japanese and Korean. Its shelf is rich in huge reserves of gas and oil. Who will develop this we alth depends on how the issue of ownership of some of the islands is decided, and how the political map will look like. The East China Sea, where lobsters and giant crabs are fished, trepangs and algae are harvested, where pearls are grown and s alt is evaporated, is a real natural treasure. Let's get to know this area better.
East China Sea on the map
This sea is part of the Pacific Ocean. It is located off the eastern coast of Asia. If we ask ourselves whether this is an inland sea, then the map shows us that it is semi-enclosed. It is separated from the main part of the Pacific Ocean by the Japanese islands of Ryukyu and Kyushu. In the west, the coast of China serves as a natural boundary. The island is considered the southern cordonTaiwan. If you look to the north, then from this side the East China Sea through the Korea Strait connects with the Yellow and Japan. It should be said that the straits near the Ryukyu Islands are very deep - up to 1572 meters. On the political map of the world, the sea is located between China, Korea and Japan. This explains the many names of the water area. After all, every nation calls it depending on its location relative to the country. The Chinese word "Donghai" means "East Sea", the Korean "Namhae" - "South". And since 2004, the Japanese Foreign Ministry has been calling this water area quite ornate. Due to territorial disputes with the PRC over Senkaku Island, and with Korea over Socotra, it is referred to in official documents as the "East Side Sea".
Geographic characteristics
The water area is more than eight hundred and thirty thousand square kilometers. With an average depth of 349 meters, the bottom is very uneven. In the west, reefs, shoals, banks are not uncommon. The complexity of navigation and the turbidity of the Yangtze, the most abundant and longest river of the Eurasian continent, aggravate. Reefs and bottom sediments, which are rich in the East China Sea in its western part, are difficult to map on the map. Earthquakes often occur here, which not only change the relief of the shelf, but also cause tsunamis. In addition, about three or four times a year, typhoons sweep through the water area, causing major damage. The maximum depth (2719 meters) is in the east of the sea. The average salinity of water is 33 ppm, at the mouth of large rivers this figure drops to 5 ‰. On the west coastthere are semi-diurnal tides up to seven and a half meters.
Climate
In the subtropical zone, where the East China Sea is located, the water never freezes. Even in its northern part in winter the temperature does not drop below +7 °C. The coldest time here is in February. But even then, in the south of the water area, the water has a temperature index of + 16 ° C. But in August it warms up to + 27-28 °C. But the weather here is very changeable. The warm Kuroshio current and cold air masses from the mainland create fogs, rains, and drizzle in winter. In summer, the East China Sea is in the monsoon zone. In the tropical belt, typhoons are born, which move in a northerly direction, causing heavy winds, storms and heavy rains. This makes navigation much more difficult. But nevertheless, the water area is the most important transport artery. The routes to the Yellow, Japanese and Philippine Seas pass through it. Therefore, because of him, conflicts arise.
Biological resources
Due to the warm climate, the East China Sea boasts a variety of flora and fauna. The number of phytoplankton, as well as green, red and brown algae, increases from west to east. Fishing, pearling and shellfish mining have long been carried out in this water area. On an industrial scale, tuna, sardine, mackerel, herring, flounder, and many types of sharks are caught here. Especially appreciated is the local "milk" fish hanos with very tender meat. It is even grown inartificial conditions. The East China Sea is also rich in waterfowl. Among them, dugongs, seals and numerous species of dolphins should be noted. But since the water area is poor in plankton, the waters of the sea never attract blue whales.
