Tsushima Basin
The or Ulleung Basin (울릉분지 ulleung bunji) is an oceanic basin located where the Sea of Japan meets the Korea Strait. It lies immediately south of Ulleung-do and Liancourt Rocks, in the eastern end of the South Korean EEZ and the western end of the Japanese EEZ. In 1978, the Japanese government registered the name "Tsushima Basin" with the International Hydrographic Bureau. In April 2006, Japan's plans to survey the region and South Korea's plans to register the name "Ulleung Basin" with the International Hydrographic Bureau resulted in a diplomatic standoff between the two countries. The two countries later agreed to address the issue "at an appropriate time." The first exploratory drilling for gas was in 1972, but gas discoveries have drawn regional interest since the late 1980s. The first commercial gas discovery was reported in 1998. Nine of 15 exploratory wells have contained gas, a rate indicating high potential prospects. The East Korea Warm Current, Ulle ...

Sea Of Japan
The Sea of Japan is the marginal sea between the Japanese archipelago, Sakhalin, the Korean Peninsula, and the mainland of the Russian Far East. The Japanese archipelago separates the sea from the Pacific Ocean. Like the Mediterranean Sea, it has almost no tides due to its nearly complete enclosure from the Pacific Ocean. This isolation also affects faunal diversity and salinity, both of which are lower than in the open ocean. The sea has no large islands, bays or capes. Its water balance is mostly determined by the inflow and outflow through the straits connecting it to the neighboring seas and the Pacific Ocean. Few rivers discharge into the sea and their total contribution to the water exchange is within 1%. The seawater has an elevated concentration of dissolved oxygen that results in high biological productivity. Therefore, fishing is the dominant economic activity in the region. The intensity of shipments across the sea has been moderate owing to political issues, but it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Korea Strait
The Korea Strait is a sea passage in East Asia between Korea and Japan, connecting the East China Sea, the Yellow Sea and the Sea of Japan in the northwest Pacific Ocean. The strait is split by the Tsushima Island into the Western Channel and the Tsushima Strait or Eastern Channel. Geography To the north, the Korea Strait is bounded by the southern coast of the Korean Peninsula. And to the south, it by the southwestern Japanese islands of Kyūshū and Honshū. It is about wide and averages about 90 to 100 meters (300 ft) deep. Tsushima Island divides the Korea Strait into the western channel and the Tsushima Strait. The western channel is deeper (up to 227 meters) and narrower than the Tsushima Strait. Currents A branch of the Kuroshio Current passes through the strait. Its warm branch is sometimes called the Tsushima Current. Originating along the Japanese islands this current passes through the Sea of Japan then divides along either shore of Sakhalin Isla ...

Oceanic Basin
In hydrology, an oceanic basin (or ocean basin) is anywhere on Earth that is covered by seawater. Geologically, ocean basins are large geologic basins that are below sea level. Most commonly the ocean is divided into basins following the continents distribution: the North and South Atlantic (together approximately 75 million km2/ 29 million mi2), North and South Pacific (together approximately 155 million km2/ 59 million mi2), Indian Ocean (68 million km2/ 26 million mi2) and Arctic Ocean (14 million km2/ 5.4 million mi2). Also recognized is the Southern Ocean (20 million km2/ 7 million mi2). All ocean basins collectively cover 71% of the Earth's surface, and together they contain almost 97% of all water on the planet. They have an average depth of almost 4 km (about 2.5 miles).

Liancourt Rocks
The Liancourt Rocks, also known by their Korean name of Dokdo or their Japanese name of Takeshima,; ; . form a group of islets in the Sea of Japan between the Korean peninsula and the Japanese archipelago. The Liancourt Rocks comprise two main islets and 35 smaller rocks; the total surface area of the islets is and the highest elevation of is on the West Islet. The Liancourt Rocks lie in rich fishing grounds that may contain large deposits of natural gas. The English name ''Liancourt Rocks'' is derived from , the name of a French whaling ship that came close to being wrecked on the rocks in 1849. While South Korea controls the islets, its sovereignty over them is Liancourt Rocks dispute, contested by Japan. North Korea also claims the territory. South Korea classifies the islets as Dokdo-Ri (administrative division), ri, Ulleung-Eup (administrative division), eup, Ulleung County, North Gyeongsang Province, while Japan classifies the islands as part of Okinoshima, Shima ...

International Hydrographic Bureau
The International Hydrographic Organization (IHO) is an intergovernmental organisation representing hydrography. , the IHO comprised 98 Member States. A principal aim of the IHO is to ensure that the world's seas, oceans and navigable waters are properly surveyed and charted. It does this through the setting of international standards, the co-ordination of the endeavours of the world's national hydrographic offices, and through its capacity building program. The IHO enjoys observer status at the United Nations, where it is the recognised competent authority on hydrographic surveying and nautical charting. When referring to hydrography and nautical charting in Conventions and similar Instruments, it is the IHO standards and specifications that are normally used. History The IHO was established in 1921 as the International Hydrographic Bureau (IHB). The present name was adopted in 1970, as part of a new international Convention on the IHO adopted by the then member nations. T ...

East Korea Warm Current
The East Korea Warm Current(EKWC) (동한난류(東韓暖流),동한해류(東韓海流),東韓鮮流), is an ocean current in the Sea of Japan (East Sea). It branches off from the Tsushima Current at the eastern end of the Korea Strait, and flows north along the southeastern coast of the Korean Peninsula. Between 36° and 38° N, it encounters the North Korea Cold Current and veers southeast into the open sea. The boundary between the two currents fluctuates throughout the year, creating large eddies. As it flows northeastward, the East Korea current eventually rejoins the Tsushima Current. It's very hot and rainy in the summer.

Continental Shelf
A continental shelf is a portion of a continent that is submerged under an area of relatively shallow water, known as a shelf sea. Much of these shelves were exposed by drops in sea level during glacial periods. The shelf surrounding an island is known as an ''insular shelf''. The continental margin, between the continental shelf and the abyssal plain, comprises a steep continental slope, surrounded by the flatter continental rise, in which sediment from the continent above cascades down the slope and accumulates as a pile of sediment at the base of the slope. Extending as far as 500 km (310 mi) from the slope, it consists of thick sediments deposited by turbidity currents from the shelf and slope. The continental rise's gradient is intermediate between the gradients of the slope and the shelf. Under the United Nations Convention on the Law of the Sea, the name continental shelf was given a legal definition as the stretch of the seabed adjacent to the shores of a par ...
