Myeongnyang Strait
Myeongnyang Strait () is a strait separating the mainland of South Korea with the island Jindo. It separates Jindo County and Haenam County, and is located in South Jeolla Province. It is also called Uldolmok (). Etymology The strait's original name was the native Korean term Uldolmok, which refers to reported loud sounds made by its rapid currents. When that name is rendered in Hanja (Chinese characters), those characters can be read as "Myeongnyang", hence the current popular name. Description The strait is about wide at the narrowest point. The average width is around . It widens from east to west. At high tide, the water speed reaches 11.5 knots and the depth reaches . The strait has proved important at several points in Korean history. The seclusion it provided allowed the Sambyeolcho Rebellion to take refuge here in 1271. In 1597, during the Imjin War, the Korean admiral, Yi Sun-sin, achieved a decisive victory in the Battle of Myeongnyang although he was massively out ...

Strait
A strait is a water body connecting two seas or water basins. The surface water is, for the most part, at the same elevation on both sides and flows through the strait in both directions, even though the topography generally constricts the flow somewhat. In some straits there is a dominant directional current. Most commonly, the strait is a narrowing channel that lies between two land masses. Straits are loci for sediment accumulation, with sand-size deposits usually occurring on the two strait exits, forming subaqueous fans or deltas. Some straits are not navigable because, for example, they are too narrow or too shallow, or because of an unnavigable reef or archipelago. Terminology The terms '' channel'', ''pass'', or ''passage'' can be synonymous and used interchangeably with ''strait'', although each is sometimes differentiated with varying senses. In Scotland, '' firth'' or ''Kyle'' are also sometimes used as synonyms for strait. Many straits are economically impor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Imjin War
The Imjin War () was a series of two Japanese invasions of Korea: an initial invasion in 1592 also individually called the "Imjin War", a brief truce in 1596, and a second invasion in 1597 called the Chŏngyu War (). The conflict ended in 1598 with the withdrawal of Japanese forces from the Korean Peninsula after a military stalemate in Korea's southern provinces. The invasions were launched by Toyotomi Hideyoshi with the intent of conquering the Korean Peninsula and China proper, which were ruled by the Joseon and Ming dynasty, Ming dynasties, respectively. Azuchi–Momoyama period, Japan quickly succeeded in occupying large portions of the Korean Peninsula, but the contribution of reinforcements by the Ming, "(Korean) war minister Yi Hang-bok pointed out that assistance from China was the only way Korea could survive." as well as the disruption of Japanese supply fleets along the western and southern coasts by the Joseon Navy, "His naval victories were to prove decisive in t ...

Geography Of South Korea
South Korea is located in East Asia, on the southern portion of the Korean Peninsula located out from the far east of the Asian landmass. The only country that shares a land border with South Korea is North Korea, lying to the north with of the border running along the Korean Demilitarized Zone. South Korea is mostly surrounded by water and has of coast line along three seas: to the west is the Yellow Sea (called ''Sohae'' ; in South Korea, literally means west sea), to the south is the East China Sea, and to the east is the Sea of Japan (called '' Donghae'' ; in South Korea, literally means east sea). Geographically, South Korea's landmass is approximately . of South Korea are occupied by water. The approximate coordinates are 37° North, 128° East.

Cable-stayed Bridge
A cable-stayed bridge has one or more ''towers'' (or ''pylons''), from which wire rope, cables support the bridge deck. A distinctive feature are the cables or wikt:stay#Etymology 3, stays, which run directly from the tower to the deck, normally forming a fan-like pattern or a series of parallel lines. This is in contrast to the modern suspension bridge, where the cables supporting the deck are suspended vertically from the main cable, anchored at both ends of the bridge and running between the towers. The cable-stayed bridge is optimal for spans longer than cantilever bridges and shorter than suspension bridges. This is the range within which cantilever bridges would rapidly grow heavier, and suspension bridge cabling would be more costly. Cable-stayed bridges found wide use in the late 19th century. Early examples, including the Brooklyn Bridge, often combined features from both the cable-stayed and suspension designs. Cable-stayed designs fell from favor in the early 20th ...

Tidal Forces
The tidal force or tide-generating force is the difference in gravitational attraction between different points in a gravitational field, causing bodies to be pulled unevenly and as a result are being stretched towards the attraction. It is the differential force of gravity, the net between gravitational forces, the derivative of gravitational potential, the gradient of gravitational fields. Therefore tidal forces are a residual force, a secondary effect of gravity, highlighting its spatial elements, making the closer near-side more attracted than the more distant far-side. This produces a range of tide, tidal phenomena, such as ocean tides. Earth's tides are mainly produced by the relative close gravitational field of the Moon and to a lesser extend by the stronger, but further away gravitational field of the Sun. The ocean on the side of Earth facing the Moon is being pulled by the gravity of the Moon away from Earth's crust, while on the other side of Earth there the crust is ...

Battle Of Myeongnyang
In the Battle of Myeongnyang, on October 26, 1597, the Korean Joseon Kingdom's navy, led by Admiral Yi Sun-sin, fought the Japanese navy in the Myeongnyang Strait, near Jindo Island, off the southwest corner of the Korean Peninsula. With only 13 ships remaining from Admiral Wŏn Kyun's disastrous defeat at the Battle of Chilchonryang, Admiral Yi held the strait as a "last stand" battle against the Japanese navy, who were sailing to support their land army's advance towards the Joseon capital of Hanyang (modern-day Seoul). The actual numeric strength of the Japanese fleet that Admiral Yi fought is unclear; Korean sources indicate 120 to 133 ships participated in combat, with an unknown number sitting out, up to 330 in total.Yi, Sun-sin (edited by Sohn, Pow Key) 1977 " Nanjung ilgi: War Diary of Admiral Yi Sun-Sin."

Yi Sun-sin
Yi Sun-sin (; ; April 28, 1545 – December 16, 1598) was a Korean admiral and military general known for his victories against the Japanese navy during the Imjin War in the Joseon period. Yi's courtesy name was Yŏhae (여해), and he was posthumously honored with the title Lord of Loyal Valor (). The exact number of naval engagements conducted by Admiral Yi against the Japanese is a subject of historical debate. However, it is generally accepted that he fought in at least 23 naval battles, achieving victory in all. In many of these engagements, he commanded forces that were outnumbered and poorly supplied. His most dramatic success occurred in the Battle of Myeongnyang, where he led a Korean fleet of 13 ships to victory against a Japanese fleet of at least 133.Yi Sunsin, Nanjung ilgi, p. 314 Yi died from a gunshot wound in the Battle of Noryang, the last major battle of the Imjin War, on December 16, 1598.

Sambyeolcho Rebellion
The Sambyeolcho Rebellion (1270–1273) was a Korean rebellion against the Goryeo dynasty that happened near the end of the Mongol invasions of Korea. It was suppressed by Goryeo and the Yuan dynasty. After the rebellion, Goryeo became a vassal state of the Yuan dynasty. Background From 1231, Goryeo was intermittently invaded by the Mongol Empire. During this time, Goryeo was controlled by a military regime led by the Ch'oe family. In 1232 the government under the nominal king fled to Ganghwa Island, which Mongol horse riders were unable to land on, and resisted the Mongol invasion. Because of its fragile foundation, Goryeo faced frequent rebellions. The 1258 rebellion resulted in the establishment of Ssangseong and Dongnyeong Prefectures by the Mongols. Unlike these rebels, the Sambyeolcho (Three Extraordinary Watches) were an organ of the military government. They were organized by the Ch'oe family to maintain security. However, unlike the Ch'oe private guards unit (which ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jindo (island)
Jindo () is the third largest island in South Korea. Together with a group of much smaller islands, it forms Jindo County. It is located in South Jeolla province, just off the southwest corner of the Korean peninsula. The island is separated from the mainland by the Myeongnyang Strait; however, this strait is now spanned by South Korea's longest cable-stayed bridge spanning 484 meters. Here in 1597 admiral Yi Sun-sin won the Battle of Myeongnyang, defeating a vastly superior Japanese fleet. Every year, on a variable day in the spring or summer, a narrow land pass (about 2.9 km long and up to 40 meters wide) opens for about an hour between the main Jindo Island and small Modo island as a result of tidal activity. This event attracts hundreds of thousands of tourists and is accompanied by local festivals. History The island was known and inhabited since prehistoric time. In 995, it was called Haeyangdo, and later renamed to Okju county and became one of the 14 Korean st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Knot (unit)
The knot () is a unit of speed equal to one nautical mile per hour, exactly (approximately or ). The ISO standard symbol for the knot is kn. The same symbol is preferred by the Institute of Electrical and Electronics Engineers ( IEEE), while kt is also common, especially in aviation, where it is the form recommended by the International Civil Aviation Organization ( ICAO). The knot is a non- SI unit. The knot is used in meteorology, and in maritime and air navigation. A vessel travelling at 1 knot along a meridian travels approximately one minute of geographic latitude in one hour. Definitions ;1 international knot = :1 nautical mile per hour (by definition), : (exactly), : (approximately), : (approximately), : (approximately) : (approximately). The length of the internationally agreed nautical mile is . The US adopted the international definition in 1954, having previously used the US nautical mile ().
