134-678: The GIUK gap (sometimes written G-I-UK) is an area in the northern Atlantic Ocean that forms a naval choke point . Its name is an acronym for Greenland , Iceland , and the United Kingdom , the gap being the two stretches of open ocean among these three landmasses. It separates the Norwegian Sea and the North Sea from the open Atlantic Ocean . The term is typically used in relation to military topics. The area has for some nations been considered strategically important since

268-684: A rocket system filled with explosive gunpowder materials and had three firing points. It was an effective weapon against ships . In the 8th century the Vikings appeared, although their usual style was to appear quickly, plunder, and disappear, preferably attacking undefended locations. The Vikings raided places along the coastline of England and France, with the greatest threats being in England. They would raid monasteries for their wealth and lack of formidable defenders. They also utilized rivers and other auxiliary waterways to work their way inland in

402-525: A French fleet of 80 ships under Eustace the Monk and an English fleet of 40 under Hubert de Burgh , is notable as the first recorded battle using sailing ship tactics. The battle of Arnemuiden (23 September 1338), which resulted in a French victory, marked the opening of the Hundred Years War and was the first battle involving artillery. However the battle of Sluys , fought two years later, saw

536-432: A decisive Venetian victory, giving it almost a century to enjoy Mediterranean trade domination before other European countries began expanding into the south and west. In the north of Europe, the near-continuous conflict between England and France was characterised by raids on coastal towns and ports along the coastlines and the securing of sea lanes to protect troop–carrying transports. The Battle of Dover in 1217, between

670-466: A decisive victory for Korea over the Japanese navy. In this battle, 47 Japanese warships were sunk and 12 other ships were captured whilst no Korean warship was lost. The defeats in the sea prevented the Japanese navy from providing their army with appropriate supply. Yi Sun-sin was later replaced with Admiral Won Gyun , whose fleets faced a defeat. The Japanese army, based near Busan , overwhelmed

804-604: A defeat of an Ostrogothic fleet at Sena Gallica in the Adriatic Sea . During the Muslim conquests of the 7th century, Muslim fleets first appeared, raiding Sicily in 652 (see History of Islam in southern Italy and Emirate of Sicily ), and defeating the Byzantine Navy in 655. Constantinople was saved from a prolonged Arab siege in 678 by the invention of Greek fire , an early form of flamethrower that

938-547: A fleet (the famous "wooden walls"), using the profits of the silver mines at Laurium to finance them. The first Persian campaign, in 492 BC, was aborted because the fleet was lost in a storm, but the second, in 490 BC, captured islands in the Aegean Sea before landing on the mainland near Marathon . Attacks by the Greek armies repulsed these. The third Persian campaign in 480 BC, under Xerxes I of Persia , followed

1072-633: A further Mongol invasion . Although with only scarce information, travellers passing the region, such as Ibn Battuta and Odoric of Pordenone noted that Java had been attacked by the Mongols several times, always ending in failure. After those failed invasions, Majapahit empire quickly grew and became the dominant naval power in the 14–15th century. The usage of cannons in the Mongol invasion of Java , led to deployment of cetbang cannons by Majapahit fleet in 1300s. The main warship of Majapahit navy

1206-472: A great naval expedition that occupied parts of Myanmar , Malaya , and Sumatra . In the Nusantara archipelago, large ocean going ships of more than 50 m in length and 5.2–7.8 meters freeboard are already used at least since the 2nd century AD, contacting India to China. Srivijaya empire since the 7th century AD controlled the sea of the western part of the archipelago. The Kedukan Bukit inscription

1340-623: A major threat in times of tension short of actual conflict. The September 2022 Nord Stream pipeline sabotage in the Baltic Sea proves the fragility of seabed infrastructure and underscore the need for the Danish government to maintain a strong Arctic responsibility in the GIUK gap. The GIUK gap is particularly important to the UK's Royal Navy , as any attempt by northern European forces to break into

1474-672: A military campaign of Persian emperor Darius I over the Bosporus ). During the Han dynasty (202 BC–220 AD), the Chinese began using the stern -mounted steering rudder , and they also designed a new ship type, the junk . From the late Han dynasty to the Three Kingdoms period (220–280 AD), large naval battles such as the Battle of Red Cliffs marked the advancement of naval warfare in

1608-747: A number of continental shelves , including the Canadian Arctic shelf, underlying the Canadian Arctic Archipelago , and the Russian continental shelf , which is sometimes called the "Arctic Shelf" because it is larger. The Russian continental shelf consists of three separate, smaller shelves: the Barents Shelf, Chukchi Sea Shelf and Siberian Shelf . Of these three, the Siberian Shelf is the largest such shelf in

1742-623: A platform on their ships called balai and performed boarding actions. Scattershots fired from cetbang are used to counter this type of fighting, fired at personnel. In the 12th century, China's first permanent standing navy was established by the Southern Song dynasty , the headquarters of the Admiralty stationed at Dinghai . This came about after the conquest of northern China by the Jurchen people (see Jin dynasty ) in 1127, while

1876-545: A pure ASW platform; its mission expanded following the Falklands War of 1982. The largest Russian submarine drills through the GIUK gap were operations Aport and Atrina, in 1985 and 1987, respectively, when the Soviets deployed several SSNs near the U.S. coast before the 1985 Gorbachev–Reagan meeting . The Soviets planned to use the GIUK gap to intercept any NATO ships, especially aircraft carriers, heading towards

2010-513: A sort of bridge or deck above the oarsmen, and some sort of ram protruding from the bow. No written mention of strategy or tactics seems to have survived. Josephus Flavius (Antiquities IX 283–287) reports a naval battle between Tyre and the king of Assyria who was aided by the other cities in Phoenicia. The battle took place off the shores of Tyre. Although the Tyrian fleet was much smaller,

2144-793: A view to attacking Allied shipping convoys , but Allied blocking efforts in the North Sea and in the GIUK gap impeded such break-outs. British forces occupied the Faroe Islands in April 1940, and Iceland in May 1940; the United States took over effective control of Greenland in 1940. But the German Kriegsmarine profited greatly from the fall of France in June 1940, after which German submarines could operate from bases on

2278-716: Is Molloy Hole in the Fram Strait , at about 5,550 m (18,210 ft). The two major basins are further subdivided by ridges into the Canada Basin (between Beaufort Shelf of North America and the Alpha Ridge ), Makarov Basin (between the Alpha and Lomonosov Ridges), Amundsen Basin (between Lomonosov and Gakkel ridges), and Nansen Basin (between the Gakkel Ridge and the continental shelf that includes

2412-449: Is a navy . Naval operations can be broadly divided into riverine/littoral applications ( brown-water navy ), open-ocean applications ( blue-water navy ), between riverine/littoral and open-ocean applications ( green-water navy ), although these distinctions are more about strategic scope than tactical or operational division. The strategic offensive purpose of naval warfare is projection of force by water, and its strategic defensive purpose

2546-414: Is a section referred to as the sub-surface layer. It is a product of Atlantic water that enters through canyons and is subjected to intense mixing on the Siberian Shelf. As it is entrained, it cools and acts a heat shield for the surface layer on account of weak mixing between layers. However, over the past couple of decades a combination of the warming and the shoaling of Atlantic water are leading to

2680-658: Is also a key supply line between the US and its European allies. With war on-going in Ukraine , NATO and the US are showing renewed interest in the GIUK gap, positioning Denmark to be a key player in matters of broader European security and increasing the gap's strategic importance to the Danish Realm . Until 2007, the Faroe Islands were home to an air surveillance radar station, providing vital radar coverage during

2814-477: Is cloudy year-round, with mean cloud cover ranging from 60% in winter to over 80% in summer. The temperature of the surface water of the Arctic Ocean is fairly constant at approximately −1.8 °C (28.8 °F), near the freezing point of seawater . The density of sea water, in contrast to fresh water, increases as it nears the freezing point and thus it tends to sink. It is generally necessary that

2948-565: Is contained in a polar climate characterized by persistent cold and relatively narrow annual temperature ranges. Winters are characterized by the polar night , extreme cold, frequent low-level temperature inversions, and stable weather conditions. Cyclones are only common on the Atlantic side. Summers are characterized by continuous daylight ( midnight sun ), and air temperatures can rise slightly above 0 °C (32 °F). Cyclones are more frequent in summer and may bring rain or snow. It

3082-677: Is predominantly cyclonic on the Eurasian side and anticyclonic in the Canadian Basin . Water enters from both the Pacific and Atlantic Oceans and can be divided into three unique water masses. The deepest water mass is called Arctic Bottom Water and begins around 900 m (3,000 ft) depth. It is composed of the densest water in the World Ocean and has two main sources: Arctic shelf water and Greenland Sea Deep Water. Water in

3216-475: Is taking further steps to equip its ASW-frigates with sonar equipment, making them better equipped to detect and track submarines in the Arctic Ocean , and particularly in the GIUK gap. In addition, the Danish government is equipping its Seahawk helicopters with sonar equipment and torpedoes. The upgrades have yet to be delivered, however, with delivery projections estimating 2024 at the earliest. During

3350-495: Is the highest volumetric inflow to the Arctic Ocean, equalling about 10 times that of the Pacific inflow, and it creates the Arctic Ocean Boundary Current. It flows slowly, at about 0.02 m/s. Atlantic Water has the same salinity as Arctic Bottom Water but is much warmer (up to 3 °C [37 °F]). In fact, this water mass is actually warmer than the surface water and remains submerged only due to

3484-459: Is the oldest record of Indonesian military history, and noted a 7th-century Srivijayan sacred siddhayatra journey led by Dapunta Hyang Sri Jayanasa . He was said to have brought 20,000 troops, including 312 people in boats and 1,312 foot soldiers. The 10th century Arab text Ajayeb al-Hind (Marvels of India) gives an account of an invasion in Africa by people called Wakwak or Waqwaq , probably

3618-476: Is to challenge the similar projection of force by enemies. Mankind has fought battles on the sea for more than 3,000 years. Even in the interior of large landmasses, transportation before the advent of extensive railways was largely dependent upon rivers , lakes , canals , and other navigable waterways . The latter were crucial in the development of the modern world in the United Kingdom, America,

3752-546: The daimyōs to dispatch troops to Joseon Korea to conquer Ming China. The Japanese army which landed at Pusan on 12 April 1502 occupied Seoul within a month. The Korean king escaped to the northern region of the Korean peninsula and Japan completed occupation of Pyongyang in June. The Korean navy then led by Admiral Yi Sun-sin defeated the Japanese navy in consecutive naval battles, namely Okpo, Sacheon, Tangpo and Tanghangpo. The Battle of Hansando on 14 August 1592 resulted in

3886-687: The Arctic Mediterranean Sea . It has also been described as an estuary of the Atlantic Ocean . It is also seen as the northernmost part of the all-encompassing world ocean . The Arctic Ocean includes the North Pole region in the middle of the Northern Hemisphere and extends south to about 60°N . The Arctic Ocean is surrounded by Eurasia and North America, and the borders follow topographic features:

4020-894: The Axumite Kingdom in modern-day Ethiopia , the Arab traveller Sa'd ibn Abi-Waqqas sailed from there to Tang China during the reign of Emperor Gaozong . Two decades later, he returned with a copy of the Quran , establishing the first Islamic mosque in China, the Mosque of Remembrance in Guangzhou . A rising rivalry followed between the Arabs and Chinese for control of trade in the Indian Ocean. In his book Cultural Flow Between China and

4154-744: The Bering Strait on the Pacific side and the Greenland Scotland Ridge on the Atlantic side. It is mostly covered by sea ice throughout the year and almost completely in winter . The Arctic Ocean's surface temperature and salinity vary seasonally as the ice cover melts and freezes; its salinity is the lowest on average of the five major oceans, due to low evaporation , heavy fresh water inflow from rivers and streams, and limited connection and outflow to surrounding oceanic waters with higher salinities. The summer shrinking of

GIUK gap - Misplaced Pages Continue

4288-476: The Cold War , Russia relied on the ability of its nuclear submarines to pass through the GIUK gap in order to ensure maximum military capability. The introduction of long-range precision strike weapons, however, have reduced the significance of the GIUK gap in relation to intercontinental attacks and made it possible for Russia to target North American sites from safer waters, such as the Norwegian Sea . Still,

4422-421: The Cold War . In light of broader geopolitical changes, such as the Russian invasion of Ukraine , c. 2022, the station was undergoing preparations to be reopened, closing an important surveillance gap in the GIUK gap. Maintaining thorough surveillance of the GIUK gap is crucial in order to ensure that sea lines of communication (SLOCs) and supply lines are uninterrupted between NATO's European members and

4556-608: The Cretaceous period, the Canadian Basin opened, and tectonic activity due to the assembly of Alaska caused hydrocarbons to migrate toward what is now Prudhoe Bay. At the same time, sediments shed off the rising Canadian Rockies built out the large Mackenzie Delta. The rifting apart of the supercontinent Pangea , beginning in the Triassic period, opened the early Atlantic Ocean. Rifting then extended northward, opening

4690-614: The Eurasian Basin , which is 4,000–4,500 m (13,100–14,800 ft) deep, and the Amerasian Basin (sometimes called the North American or Hyperborean Basin), which is about 4,000 m (13,000 ft) deep. The bathymetry of the ocean bottom is marked by fault block ridges, abyssal plains , ocean deeps , and basins. The average depth of the Arctic Ocean is 1,038 m (3,406 ft). The deepest point

4824-455: The Faroe Islands to assist in securing the GIUK gap and the wider Arctic for its allies. In doing so, Denmark has arguably acquired a sense of goodwill from particularly the US government and NATO . The Danish government views the Arctic as a central component of its foreign security policy and will continue to expand its spending, surveillance and military presence in the region. Despite

4958-655: The Franz Josef Land ). The crystalline basement rocks of mountains around the Arctic Ocean were recrystallized or formed during the Ellesmerian orogeny, the regional phase of the larger Caledonian orogeny in the Paleozoic Era. Regional subsidence in the Jurassic and Triassic periods led to significant sediment deposition, creating many of the reservoirs for current day oil and gas deposits. During

5092-584: The Independence I and Independence II cultures of northeastern Canada and Greenland ( c.  2400–1800 BC and c.  800–1 BC ); and the Groswater of Labrador and Nunavik . The Dorset culture spread across Arctic North America between 500 BC and AD 1500. The Dorset were the last major Paleo-Eskimo culture in the Arctic before the migration east from present-day Alaska of

5226-531: The Low Countries and northern Germany , because they enabled the bulk movement of goods and raw material , which supported the nascent Industrial Revolution . Prior to 1750, materials largely moved by river barge or sea vessels. Thus armies, with their exorbitant needs for food, ammunition and fodder, were tied to the river valleys throughout the ages. Pre-recorded history (Homeric Legends, e.g. Troy ), and classical works such as The Odyssey emphasize

5360-554: The North Atlantic both in the gap and beyond, and the US and NATO rely on the Kingdom of Denmark to assist in protecting this critical infrastructure, including the vast number of seabed data cables. The Russian fleet has in recent years strategically upgraded its capabilities for covert subsea operations related to the targeting of seabed infrastructure and reports of Russian "mapping" of critical seabed infrastructure in

5494-418: The North Sea and the seabed around Denmark are increasing. NATO intelligence and security officials confirm these reports, warning that Russia has both the intent and necessary capabilities to target critical seabed installations if they so choose. While such infrastructure has always been associated with some risk, the dependency of Denmark and its allies on them are only increasing and is therefore posing

The few expeditions to penetrate much beyond the Arctic Circle in that era added only small islands, such as Novaya Zemlya (11th century) and Spitzbergen (1596), though, since these were often surrounded by pack-ice , their northern limits were not so clear. The makers of navigational charts , more conservative than some of

5896-406: The Siege of Fort Zeelandia , the first time China had defeated a western power. The Chinese used cannons and ships to bombard the Dutch into surrendering. In the Sengoku period of Japan, Oda Nobunaga unified the country by military power. However, he was defeated by the Mōri clan 's navy. Nobunaga invented the Tekkosen (large Atakebune equipped with iron plates) and defeated 600 ships of

6030-503: The Silk Road and the Mediterranean in general for centuries. For three centuries, Vikings raided and pillaged far into central Russia and Ukraine , and even to distant Constantinople (both via the Black Sea tributaries, Sicily , and through the Strait of Gibraltar ). Gaining control of the sea has largely depended on a fleet's ability to wage sea battles. Throughout most of naval history, naval warfare revolved around two overarching concerns, namely boarding and anti-boarding. It

6164-424: The Thule people , ancestors of the modern Inuit . The Thule Tradition lasted from about 200 BC to AD 1600, arising around the Bering Strait and later encompassing almost the entire Arctic region of North America. The Thule people were the ancestors of the Inuit, who now live in Alaska, Northwest Territories , Nunavut , Nunavik (northern Quebec), Labrador and Greenland. For much of European history ,

6298-479: The United States . Military bases, space bases, surveillance drones and radar installations in both Greenland and the Faroe Islands can help ensure proper visibility in the region, and assist in anti-submarine warfare (ASW) in case of actual conflict. In 2021, Denmark unveiled a $ 250m investment in surveillance capabilities in Greenland and the Faroe Islands . Responding to requests from NATO for Denmark to play its part in securing Arctic waters , Denmark

6432-420: The largest naval battles in history . In the 15th century, the Chinese admiral Zheng He was assigned to assemble a massive fleet for several diplomatic missions abroad , sailing throughout the waters of the South East Pacific and the Indian Ocean. During his missions, on several occasions Zheng's fleet came into conflict with pirates . Zheng's fleet also became involved in a conflict in Sri Lanka , where

6566-409: The 12th century, Srivijaya is primarily land-based polity rather than maritime power, fleets are available but acted as logistical support to facilitate the projection of land power. Later, the naval strategy degenerated to raiding fleet. Their naval strategy was to coerce merchant ships to dock in their ports, which if ignored, they will send ships to destroy the ship and kill the occupants. In 1293,

6700-573: The 1950s – an example of a SOSUS "sound surveillance system". This deployment of sonar surveillance in the gap, and elsewhere, hampered the Soviet Northern Fleet 's ability to deploy its submarines without detection. The Royal Navy's primary mission during the Cold War, excluding its nuclear deterrent role, involved anti-submarine warfare (ASW). The development of the Invincible -class ASW aircraft carriers stemmed from this doctrine : their primary mission involved anti-submarine warfare using Sea King helicopters. The Type 23 frigate originated as

6834-412: The Arctic Ocean as mafic oceanic crust material erupted out of a branch of Mid-Atlantic Ridge. The Amerasia Basin may have opened first, with the Chukchi Borderland moved along to the northeast by transform faults. Additional spreading helped to create the "triple-junction" of the Alpha-Mendeleev Ridge in the Late Cretaceous epoch . Throughout the Cenozoic Era, the subduction of the Pacific plate,

6968-427: The Arctic Ocean has a uniquely complex system of water flow. It resembles some hydrological features of the Mediterranean Sea , referring to its deep waters having only limited communication through the Fram Strait with the Atlantic Basin , "where the circulation is dominated by thermohaline forcing". The Arctic Ocean has a total volume of 18.07 × 10 km , equal to about 1.3% of the World Ocean. Mean surface circulation

7102-403: The Arctic Ocean. Much of the Arctic ice pack is also covered in snow for about 10 months of the year. The maximum snow cover is in March or April—about 20–50 cm (7.9–19.7 in) over the frozen ocean. The climate of the Arctic region has varied significantly during the Earth's history. During the Paleocene–Eocene Thermal Maximum 55 million years ago, when the global climate underwent

7236-402: The Arctic Ocean: Different authorities put various marginal seas in either the Arctic Ocean or the Atlantic Ocean, including: Hudson Bay , Baffin Bay , the Norwegian Sea , and Hudson Strait . The main islands and archipelagos in the Arctic Ocean are, from the prime meridian west: There are several ports and harbours on the Arctic Ocean. The ocean's Arctic shelf comprises

7370-450: The Atlantic Ocean for Soviet submarines operating from their bases on the Kola Peninsula . NATO worried that if the Cold War "turned hot", naval convoys reinforcing Europe from the U.S. would suffer unacceptable losses if Soviet submarines could operate in the North Atlantic. The United States and Britain based much of their post-war naval strategy on blocking the gap, installing a chain of underwater listening posts right across it during

7504-484: The Atlantic Ocean that cannot easily be blocked at a choke point by the Royal Navy. Since the beginning of the 20th century, the exploitation of the GIUK gap by northern forces and measures to patrol and secure the gap by opposing forces have played an important role in naval and in overall military planning. From the start of World War II in 1939, German ships used the gap to break out from their bases in northern Germany (and from occupied Norway after April 1940) with

7638-458: The Black Sea, raiding the coasts of Anatolia and Thrace, and crossing into the Aegean Sea, plundering mainland Greece (including Athens and Sparta) and going as far as Crete and Rhodes. In the twilight of the Roman Empire in the late 4th century, examples include that of Emperor Majorian , who, with the help of Constantinople, mustered a large fleet in a failed effort to expel the Germanic invaders from their recently conquered African territories, and

7772-408: The Canadian Archipelago. As noted, the process of ice formation and movement is a key driver in Arctic Ocean circulation and the formation of water masses. With this dependence, the Arctic Ocean experiences variations due to seasonal changes in sea ice cover. Sea ice movement is the result of wind forcing, which is related to a number of meteorological conditions that the Arctic experiences throughout

7906-437: The East. In the latter engagement, the allied forces of Sun Quan and Liu Bei destroyed a large fleet commanded by Cao Cao in a fire-based naval attack. In terms of seafaring abroad, arguably one of the first Chinese to sail into the Indian Ocean and to reach Sri Lanka and India by sea was the Buddhist monk Faxian in the early 5th century, although diplomatic ties and land trade to Persia and India were established during

8040-408: The European region of the Arctic Ocean was heavily contested : the Allied commitment to resupply the Soviet Union via its northern ports was opposed by German naval and air forces. Since 1954 commercial airlines have flown over the Arctic Ocean (see Polar route ). The Arctic Ocean occupies a roughly circular basin and covers an area of about 14,056,000 km (5,427,000 sq mi), almost

8174-410: The Fram Strait is what allows for both inflow and outflow on the Atlantic side of the Arctic Ocean. Because of this, it is influenced by the Coriolis force , which concentrates outflow to the East Greenland Current on the western side and inflow to the Norwegian Current on the eastern side. Pacific water also exits along the west coast of Greenland and the Hudson Strait (1–2 Sv), providing nutrients to

8308-428: The French coast. The origin of the term "gap" dates to this period, when there was a gap in air coverage known as the Mid-Atlantic gap or the "Greenland air gap". This gap was an area that land-based aircraft could not reach and where, as a result, they could not carry out their anti-submarine duties. The GIUK gap again became the focus of naval planning in the 1950s, as it represented the only available outlet into

8442-402: The GIUK gap remains the obvious access point for Russian military operations in the wider North Atlantic Ocean since most of Russia's highest quality naval capabilities are deployed in the Northern fleet , making the GIUK gap a significant transit route. For NATO allies, the GIUK gap is vital in terms of barrier defense for sea lines of communication protection. SLOCs are vulnerable in

8576-411: The GIUK gap. Crossing the GIUK gap was a major strategic move for Ocean Venture in 1992, in which 84 NATO ships, including 4 US aircraft carriers, departed from their usual August exercise pattern, deployed a decoy south toward the mid-Atlantic, and then entered waters in a move that had historically been associated with a risk of destabilizing détente . In late October 2019, a week before Commander of

8710-438: The Greeks commanded the Aegean, but not harmoniously. After several minor wars, tensions exploded into the Peloponnesian War (431 BC) between Athens' Delian League and the Spartan Peloponnese . Naval strategy was critical; Athens walled itself off from the rest of Greece, leaving only the port at Piraeus open, and trusting in its navy to keep supplies flowing while the Spartan army besieged it. This strategy worked, although

8844-517: The Japanese army returned to Japan by the end of December. In 1609, the Tokugawa shogunate ordered the abandonment of warships to the feudal lord . The Japanese navy stagnated until the Meiji period . In ancient China , the first known naval battles took place during the Warring States period (481–221 BC) when vassal lords battled one another. Chinese naval warfare in this period featured grapple-and-hook, as well as ramming tactics with ships called "stomach strikers" and "colliding swoopers". It

8978-410: The Jin to the north, until the Mongols finally conquered all of China. After the Song dynasty, the Mongol-led Yuan dynasty of China was a powerful maritime force in the Indian Ocean. The Yuan emperor Kublai Khan attempted to invade Japan twice with large fleets (of both Mongols and Chinese), in 1274 and again in 1281, both attempts being unsuccessful (see Mongol invasions of Japan ). Building upon

9112-409: The King of Ceylon traveled back to Ming China afterwards to make a formal apology to the Yongle Emperor . The Ming imperial navy defeated a Portuguese navy led by Martim Afonso de Sousa in 1522. The Chinese destroyed one vessel by targeting its gunpowder magazine, and captured another Portuguese ship. A Ming army and navy led by Koxinga defeated a western power, the Dutch East India Company , at

9246-474: The Korean kingdom of Silla (see also Unified Silla ) and expelled the Korean kingdom of Baekje which were supported by Japanese naval forces from the Korean peninsula (see Battle of Baekgang ) and helped Silla overcome its rival Korean kingdoms, Baekje and Goguryeo , by 668. In addition, the Tang had maritime trading, tributary, and diplomatic ties as far as modern Sri Lanka , India, Islamic Iran and Arabia , as well as Somalia in East Africa . From

9380-423: The Korean navy in the Battle of Chilcheollyang on 28 August 1597 and began advancing toward China. This attempt was stopped when the reappointed Admiral Yi, won the battle of Myeongnyang . The Wanli Emperor of Ming China sent military forces to the Korean peninsula. Yi Sun-sin and Chen Lin continued to successfully engage the Japanese navy with 500 Chinese warships and the strengthened Korean fleet. In 1598,

9514-419: The Lomonosov Ridge, which appears to be continental crust separated from the Barents-Kara Shelf in the Paleocene and then starved of sediment. It may contain up to 10 billion barrels of oil. The Gakkel Ridge rift is also poorly understand and may extend into the Laptev Sea. In large parts of the Arctic Ocean, the top layer (about 50 m [160 ft]) is of lower salinity and lower temperature than

9648-620: The Malay people of Srivijaya or Javanese people of Mataram kingdom , in 945–946 CE. They arrived at the coast of Tanganyika and Mozambique with 1000 boats and attempted to take the citadel of Qanbaloh, though eventually failed. The reason of the attack is because that place had goods suitable for their country and for China, such as ivory, tortoise shells, panther skins, and ambergris , and also because they wanted black slaves from Bantu people (called Zeng or Zenj by Arabs, Jenggi by Javanese) who were strong and make good slaves. Before

9782-627: The Mediterranean began to wane, the Italian trading towns of Genoa , Pisa , and Venice stepped in to seize the opportunity, setting up commercial networks and building navies to protect them. At first the navies fought with the Arabs (off Bari in 1004, at Messina in 1005), but then they found themselves contending with Normans moving into Sicily, and finally with each other. The Genoese and Venetians fought four naval wars, in 1253–1284, 1293–1299, 1350–1355, and 1378–1381. The last ended with

9916-722: The Mongol Yuan dynasty launched an invasion to Java . The Yuan sent 500–1000 ships and 20,000–30,000 soldiers, but was ultimately defeated on land by surprise attack , forcing the army to fall back to the beach. In the coastal waters, Javanese junks had already attacked the Mongol ships. After all of the troops had boarded the ships on the coast, the Yuan army battled the Javanese fleet. After repelling it, they sailed back to Quanzhou . Javanese naval commander Aria Adikara intercepted

10050-540: The Mōri navy with six armored warships ( Battle of Kizugawaguchi ). The navy of Nobunaga and his successor Toyotomi Hideyoshi employed clever close-range tactics on land with arquebus rifles, but also relied upon close-range firing of muskets in grapple-and-board style naval engagements. When Nobunaga died in the Honnō-ji incident , Hideyoshi succeeded him and completed the unification of the whole country. In 1592, Hideyoshi ordered

10184-776: The North American polar region goes back at least 17,000–50,000 years, during the Wisconsin glaciation . At this time, falling sea levels allowed people to move across the Bering land bridge that joined Siberia to northwestern North America (Alaska), leading to the Settlement of the Americas . Early Paleo-Eskimo groups included the Pre-Dorset ( c.  3200–850 BC ); the Saqqaq culture of Greenland (2500–800 BC);

10318-598: The Outside World , Shen Fuwei notes that maritime Chinese merchants in the 9th century were landing regularly at Sufala in East Africa to cut out Arab middle-men traders. The Chola dynasty of medieval India was a dominant seapower in the Indian Ocean , an avid maritime trader and diplomatic entity with Song China. Rajaraja Chola I (reigned 985 to 1014) and his son Rajendra Chola I (reigned 1014–42), sent

10452-511: The Song imperial court fled south from Kaifeng to Hangzhou . Equipped with the magnetic compass and knowledge of Shen Kuo 's famous treatise (on the concept of true north ), the Chinese became proficient experts of navigation in their day. They raised their naval strength from a mere 11 squadrons of 3,000 marines to 20 squadrons of 52,000 marines in a century's time. Employing paddle wheel crafts and trebuchets throwing gunpowder bombs from

10586-648: The Soviet Union. Ships and submarines as well as Tupolev Tu-142 maritime-surveillance aircraft aimed to track any threatening ships. The advent of longer-ranged Soviet submarine-launched ballistic missiles (SLBMs) allowed the Soviet Navy to deploy their ballistic missile submarine (SSBNs) within protected bastions in the Barents Sea and reduced their need to transit the GIUK gap. The much reduced, post-Cold War Russian Navy has even less need to transit

10720-581: The Tyrians defeated their enemies. The Greeks of Homer just used their ships as transport for land armies, but in 664 BC there is a mention of a battle at sea between Corinth and its colony city Corcyra . Ancient descriptions of the Persian Wars were the first to feature large-scale naval operations, not just sophisticated fleet engagements with dozens of triremes on each side, but combined land-sea operations. It seems unlikely that all this

10854-505: The Vikings, only two of which were not beaten back or captured. The Vikings also fought several sea battles among themselves. This was normally done by binding the ships on each side together, thus essentially fighting a land battle on the sea. However the fact that the losing side could not easily escape meant that battles tended to be hard and bloody. The Battle of Svolder is perhaps the most famous of these battles. As Muslim power in

10988-665: The average winter value of 15,600,000 km (6,023,200 sq mi). The seasonal variations are about 7,000,000 km (2,702,700 sq mi), with the maximum in April and minimum in September. The sea ice is affected by wind and ocean currents, which can move and rotate very large areas of ice. Zones of compression also arise, where the ice piles up to form pack ice. Icebergs occasionally break away from northern Ellesmere Island , and icebergs are formed from glaciers in western Greenland and extreme northeastern Canada. Icebergs are not sea ice but may become embedded in

11122-506: The beginning of the 20th century. Comprising Greenland , the Faroe Islands and Denmark , the Kingdom of Denmark is an Arctic state alongside seven other countries whose territories cover the Arctic region. All matters of foreign policy for both Greenland and the Faroe Islands fall within the jurisdiction of the Danish government. The Danish government has historically used its jurisdiction over foreign policy in both Greenland and

11256-600: The close quarters likely contributed to the plague that killed many Athenians in 429 BC. There were a number of sea battles between galleys ; at Rhium , Naupactus , Pylos , Syracuse , Cynossema , Cyzicus , Notium . But the end came for Athens in 405 BC at Aegospotami in the Hellespont , where the Athenians had drawn up their fleet on the beach, and were surprised by the Spartan fleet, who landed and burned all

11390-694: The collision of India with Eurasia, and the continued opening of the North Atlantic created new hydrocarbon traps. The seafloor began spreading from the Gakkel Ridge in the Paleocene Epoch and the Eocene Epoch, causing the Lomonosov Ridge to move farther from land and subside. Because of sea ice and remote conditions, the geology of the Arctic Ocean is still poorly explored. The Arctic Coring Expedition drilling shed some light on

11524-567: The decks of their ships, the Southern Song dynasty became a formidable foe to the Jin dynasty during the 12th–13th centuries during the Jin–Song Wars . There were naval engagements at the Battle of Caishi and Battle of Tangdao . With a powerful navy, China dominated maritime trade throughout South East Asia as well. Until 1279, the Song were able to use their naval power to defend against

11658-588: The destruction of the French fleet in a decisive action which allowed the English effective control of the sea lanes and the strategic initiative for much of the war. The Sui (581–618) and Tang (618–907) dynasties of China were involved in several naval affairs over the triple set of polities ruling medieval Korea ( Three Kingdoms of Korea ), along with engaging naval bombardments on the peninsula from Asuka period Yamato Kingdom (Japan). The Tang dynasty aided

11792-496: The earlier Han dynasty. However, Chinese naval maritime influence would penetrate into the Indian Ocean until the medieval period. The late Middle Ages saw the development of the cogs , caravels and carracks ships capable of surviving the tough conditions of the open ocean, with enough backup systems and crew expertise to make long voyages routine. In addition, they grew from 100 tons to 300 tons displacement, enough to carry cannon as armament and still have space for cargo. One of

11926-517: The end, Xerxes still had a fleet stronger than the Greeks, but withdrew anyway, and after losing at Plataea in the following year, returned to Asia Minor , leaving the Greeks their freedom. Nevertheless, the Athenians and Spartans attacked and burned the laid-up Persian fleet at Mycale , and freed many of the Ionian towns. These battles involved triremes or biremes as the standard fighting platform, and

12060-690: The eventual invasion of Britain. They wreaked havoc in Northumbria and Mercia and the rest of Anglia before being halted by Wessex. King Alfred the Great of England was able to stay the Viking invasions with a pivotal victory at the Battle of Edington. Alfred defeated Guthrum, establishing the boundaries of Danelaw in an 884 treaty. The effectiveness of Alfred's 'fleet' has been debated; Kenneth Harl has pointed out that as few as eleven ships were sent to combat

12194-501: The explorers who travelled closer and closer to the pole reported, the polar ice cap is quite thick and persists year-round. Fridtjof Nansen was the first to make a nautical crossing of the Arctic Ocean, in the Fram Expedition from 1893 to 1896. The first surface crossing of the ocean was led by Wally Herbert in 1969, in a dog sled expedition from Alaska to Svalbard , with air support. The first nautical transit of

12328-402: The focus of the battle was to ram the opponent's vessel using the boat's reinforced prow. The opponent would try to maneuver and avoid contact, or alternately rush all the marines to the side about to be hit, thus tilting the boat. When the ram had withdrawn and the marines dispersed, the hole would then be above the waterline and not a critical injury to the ship. During the next fifty years,

12462-634: The formation of Atlantic Deep Water. The overturning of this water plays a key role in global circulation and the moderation of climate. In the depth range of 150–900 m (490–2,950 ft) is a water mass referred to as Atlantic Water. Inflow from the North Atlantic Current enters through the Fram Strait, cooling and sinking to form the deepest layer of the halocline, where it circles the Arctic Basin counter-clockwise. This

12596-591: The hull of the ship in order to rip into the hull of another ship while ramming, to stab enemies in the water that had fallen overboard and were swimming, or simply to clear any possible dangerous marine animals in the path of the ship (since the ancient Chinese did believe in sea monsters; see Xu Fu for more info). Qin Shi Huang , the first emperor of the Qin dynasty (221–207 BC), owed much of his success in unifying southern China to naval power, although an official navy

12730-456: The ice has been quoted at 50%. The US National Snow and Ice Data Center (NSIDC) uses satellite data to provide a daily record of Arctic sea ice cover and the rate of melting compared to an average period and specific past years, showing a continuous decline in sea ice extent. In September 2012, the Arctic ice extent reached a new record minimum. Compared to the average extent (1979–2000), the sea ice had diminished by 49%. Human habitation in

12864-497: The increasing influence of Atlantic water heat in melting sea ice in the eastern Arctic. The most recent estimates, for 2016–2018, indicate the oceanic heat flux to the surface has now overtaken the atmospheric flux in the eastern Eurasian Basin. Over the same period the weakening halocline stratification has coincided with increasing upper ocean currents thought to be associated with declining sea ice, indicate increasing mixing in this region. In contrast direct measurements of mixing in

12998-548: The largest ships of the time, the Great Harry , displaced over 1,500 tons. Arctic Ocean Main five oceans division: Further subdivision: The Arctic Ocean is the smallest and shallowest of the world's five oceanic divisions . It spans an area of approximately 14,060,000 km (5,430,000 sq mi) and is the coldest of the world's oceans. The International Hydrographic Organization (IHO) recognizes it as an ocean, although some oceanographers call it

13132-460: The mid-14th century, the rebel leader Zhu Yuanzhang (1328–1398) seized power in the south amongst many other rebel groups. His early success was due to capable officials such as Liu Bowen and Jiao Yu , and their gunpowder weapons (see Huolongjing ). Yet the decisive battle that cemented his success and his founding of the Ming dynasty (1368–1644) was the Battle of Lake Poyang , considered one of

13266-483: The more fanciful cartographers, tended to leave the region blank, with only fragments of known coastline sketched in. This lack of knowledge of what lay north of the shifting barrier of ice gave rise to a number of conjectures. In England and other European nations, the myth of an " Open Polar Sea " was persistent. John Barrow , longtime Second Secretary of the British Admiralty , promoted exploration of

13400-497: The north polar regions remained largely unexplored and their geography conjectural. Pytheas of Massilia recorded an account of a journey northward in 325 BC, to a land he called " Eschate Thule ", where the Sun only set for three hours each day and the water was replaced by a congealed substance "on which one can neither walk nor sail". He was probably describing loose sea ice known today as " growlers " or "bergy bits"; his "Thule"

13534-400: The north pole was made in 1958 by the submarine USS Nautilus , and the first surface nautical transit occurred in 1977 by the icebreaker NS Arktika . Since 1937, Soviet and Russian manned drifting ice stations have extensively monitored the Arctic Ocean. Scientific settlements were established on the drift ice and carried thousands of kilometres by ice floes . In World War II ,

13668-517: The open Atlantic would have to be made either through the heavily defended English Channel , one of the world's busiest seaways, or through one of the exits on either side of Iceland. As the British also control the strategic port of Gibraltar at the entrance to the Mediterranean , this means Spain, France, and Portugal are the only Continental European countries that possess direct access to

13802-578: The pack ice. Icebergs pose a hazard to ships, of which the Titanic is one of the most famous. The ocean is virtually icelocked from October to June, and the superstructure of ships are subject to icing from October to May. Before the advent of modern icebreakers, ships sailing the Arctic Ocean risked being trapped or crushed by sea ice (although the Baychimo drifted through the Arctic Ocean untended for decades despite these hazards). The Arctic Ocean

13936-564: The pattern of the second in marching the army via the Hellespont while the fleet paralleled them offshore. Near Artemisium , in the narrow channel between the mainland and Euboea , the Greek fleet held off multiple assaults by the Persians, the Persians breaking through a first line, but then being flanked by the second line of ships. But the defeat on land at Thermopylae forced a Greek withdrawal, and Athens evacuated its population to nearby Salamis Island . The ensuing Battle of Salamis

14070-481: The planned conquest in China was canceled by the death of Toyotomi Hideyoshi , and the Japanese military retreated from the Korean Peninsula. On their way back to Japan, Yi Sun-sin and Chen Lin attacked the Japanese navy at the Battle of Noryang inflicting heavy damages, but the Chinese top official Deng Zilong and the Korean commander Yi Sun-sin were killed in a Japanese army counterattack. The rest of

14204-527: The region from 1818 to 1845 in search of this. In the United States in the 1850s and 1860s, the explorers Elisha Kane and Isaac Israel Hayes both claimed to have seen part of this elusive body of water. Even quite late in the century, the eminent authority Matthew Fontaine Maury included a description of the Open Polar Sea in his textbook The Physical Geography of the Sea (1883). Nevertheless, as all

14338-613: The relatively small-sized population of the Kingdom of Denmark , roughly 6 million, the Danish government's close ties to Greenland and the Faroe Islands legitimises it as an inherently important Arctic actor on matters of geopolitical security and great-power tensions. Danish assertion of sovereignty in the GIUK gap and the wider Arctic is already a key concern to the Realm and is expected to be an increasingly important component of Denmark's future responsibilities in NATO . The GIUK gap

14472-520: The rest. It remains relatively stable because the salinity effect on density is bigger than the temperature effect. It is fed by the freshwater input of the big Siberian and Canadian rivers ( Ob , Yenisei , Lena , Mackenzie ), the water of which quasi floats on the saltier, denser, deeper ocean water. Between this lower salinity layer and the bulk of the ocean lies the so-called halocline , in which both salinity and temperature rise with increasing depth. Because of its relative isolation from other oceans,

14606-663: The role of salinity in density. When water reaches the basin, it is pushed by strong winds into a large circular current called the Beaufort Gyre . Water in the Beaufort Gyre is far less saline than that of the Chukchi Sea due to inflow from large Canadian and Siberian rivers. The final defined water mass in the Arctic Ocean is called Arctic Surface Water and is found in the depth range of 150–200 m (490–660 ft). The most important feature of this water mass

14740-462: The sea that sink over the continental shelf into the western Arctic Ocean and create a halocline. This water is met by Greenland Sea Deep Water, which forms during the passage of winter storms. As temperatures cool dramatically in the winter, ice forms, and intense vertical convection allows the water to become dense enough to sink below the warm saline water below. Arctic Bottom Water is critically important because of its outflow, which contributes to

14874-674: The sea. The Persian Empire – united and strong – could not prevail against the might of the Athenian fleet combined with that of lesser city states in several attempts to conquer the Greek city states. Phoenicia 's and Egypt 's power, Carthage 's and even Rome 's largely depended upon control of the seas. So too did the Venetian Republic dominate Italy's city states, thwart the Ottoman Empire , and dominate commerce on

15008-467: The shelf region that begins as inflow from the Pacific passes through the narrow Bering Strait at an average rate of 0.8 Sverdrups and reaches the Chukchi Sea . During the winter, cold Alaskan winds blow over the Chukchi Sea, freezing the surface water and pushing this newly formed ice out to the Pacific. The speed of the ice drift is roughly 1–4 cm/s. This process leaves dense, salty waters in

15142-529: The ships. Athens surrendered to Sparta in the following year. Navies next played a major role in the complicated wars of the successors of Alexander the Great . The Roman Republic had never been much of a seafaring nation, but it had to learn. In the Punic Wars with Carthage , Romans developed the technique of grappling and boarding enemy ships with soldiers. The Roman Navy grew gradually as Rome became more involved in Mediterranean politics; by

15276-411: The size of Antarctica . The coastline is 45,390 km (28,200 mi) long. It is the only ocean smaller than Russia , which has a land area of 16,377,742 km (6,323,482 sq mi). The Arctic Ocean is surrounded by the land masses of Eurasia (Russia and Norway), North America ( Canada and the U.S. state of Alaska), Greenland, and Iceland . Note: Some parts of the areas listed in

15410-473: The submarines was reportedly testing Russian ability to breach the GIUK gap undetected and sail into the Atlantic Ocean. The drills were expected to last up to two months. The GIUK gap is also a route for migratory birds such as the northern wheatear to cross the Atlantic to reach Greenland and eastern Canada. Land: Naval warfare The armed forces branch designated for naval warfare

15544-478: The summer months. There is also evidence that the drift is associated with the phase of the Arctic Oscillation and Atlantic Multidecadal Oscillation . Much of the Arctic Ocean is covered by sea ice that varies in extent and thickness seasonally. The mean extent of the Arctic sea ice has been continuously decreasing in the last decades, declining at a rate of currently 12.85% per decade since 1980 from

15678-664: The summer, the SLP contrast is smaller, producing weaker winds. A final example of seasonal pressure system movement is the low pressure system that exists over the Nordic and Barents Seas. It is an extension of the Icelandic Low , which creates cyclonic ocean circulation in this area. The low shifts to centre over the North Pole in the summer. These variations in the Arctic all contribute to ice drift reaching its weakest point during

15812-632: The table are located in the Atlantic Ocean . Other consists of Gulfs , Straits , Channels and other parts without specific names and excludes Exclusive Economic Zones . The Arctic Ocean is connected to the Pacific Ocean by the Bering Strait and to the Atlantic Ocean through the Greenland Sea and Labrador Sea . (The Iceland Sea is sometimes considered part of the Greenland Sea, and sometimes separate.) The largest seas in

15946-528: The technological achievements of the earlier Song dynasty, the Mongols also employed early cannons upon the decks of their ships. While Song China built its naval strength, the Japanese also had considerable naval prowess. The strength of Japanese naval forces could be seen in the Genpei War , in the large-scale Battle of Dan-no-ura on 25 April 1185. The forces of Minamoto no Yoshitsune were 850 ships strong, while Taira no Munemori had 500 ships. In

16080-739: The time of the Roman Civil War and the Battle of Actium (31 BC), hundreds of ships were involved, many of them quinqueremes mounting catapults and fighting towers. Following the Emperor Augustus transforming the Republic into the Roman Empire , Rome gained control of most of the Mediterranean. Without any significant maritime enemies, the Roman navy was reduced mostly to patrolling for pirates and transportation duties. It

16214-475: The upper 100–150 m (330–490 ft) of ocean water cools to the freezing point for sea ice to form. In the winter, the relatively warm ocean water exerts a moderating influence, even when covered by ice. This is one reason why the Arctic does not experience the extreme temperatures seen on the Antarctic continent . There is considerable seasonal variation in how much pack ice of the Arctic ice pack covers

16348-493: The western Arctic indicate the Atlantic water heat remains isolated at intermediate depths even under the 'perfect storm' conditions of the Great Arctic Cyclone of 2012 . Waters originating in the Pacific and Atlantic both exit through the Fram Strait between Greenland and Svalbard Island, which is about 2,700 m (8,900 ft) deep and 350 km (220 mi) wide. This outflow is about 9 Sv. The width of

16482-628: The world; it holds large oil and gas reserves. The Chukchi shelf forms the border between Russian and the United States as stated in the USSR–USA Maritime Boundary Agreement . The whole area is subject to international territorial claims . The Chukchi Plateau extends from the Chukchi Sea Shelf. An underwater ridge , the Lomonosov Ridge , divides the deep sea North Polar Basin into two oceanic basins :

16616-547: The year. For example, the Beaufort High—an extension of the Siberian High system—is a pressure system that drives the anticyclonic motion of the Beaufort Gyre. During the summer, this area of high pressure is pushed out closer to its Siberian and Canadian sides. In addition, there is a sea level pressure (SLP) ridge over Greenland that drives strong northerly winds through the Fram Strait, facilitating ice export. In

16750-723: Was devastating to the ships in the besieging fleet. These were the first of many encounters during the Byzantine-Arab Wars . The Caliphate became the dominant naval power in the Mediterranean Sea from the 7th to 13th centuries, during what is known as the Islamic Golden Age . One of the most significant inventions in medieval naval warfare was the torpedo , invented in Syria by the Arab inventor Hasan al-Rammah in 1275. His torpedo ran on water with

16884-410: Was not yet established (see Medieval Asia section below). The people of the Zhou dynasty were known to use temporary pontoon bridges for general means of transportation, but it was during the Qin and Han dynasties that large permanent pontoon bridges were assembled and used in warfare (first written account of a pontoon bridge in the West being the oversight of the Greek Mandrocles of Samos in aiding

17018-430: Was one of the decisive engagements of history. Themistocles trapped the Persians in a channel too narrow for them to bring their greater numbers to bear, and attacked them vigorously, in the end causing the loss of 200 Persian ships vs 40 Greek. Aeschylus wrote a play about the defeat, The Persians , which was performed in a Greek theatre competition a few years after the battle. It is the oldest known surviving play. At

17152-400: Was only in the late 16th century, when gunpowder technology had developed to a considerable extent, that the tactical focus at sea shifted to heavy ordnance. Many sea battles through history also provide a reliable source of shipwrecks for underwater archaeology . A major example is the exploration of the wrecks of various warships in the Pacific Ocean . The first recorded sea battle

17286-442: Was only on the fringes of the Empire, in newly gained provinces or defensive missions against barbarian invasion, that the navy still engaged in actual warfare. While the barbarian invasions of the 4th century and later mostly occurred by land, some notable examples of naval conflicts are known. In the late 3rd century, in the reign of Emperor Gallienus , a large raiding party composed by Goths, Gepids and Heruli, launched itself in

17420-417: Was probably Norway , though the Faroe Islands or Shetland have also been suggested. Early cartographers were unsure whether to draw the region around the North Pole as land (as in Johannes Ruysch 's map of 1507, or Gerardus Mercator 's map of 1595) or water (as with Martin Waldseemüller 's world map of 1507). The fervent desire of European merchants for a northern passage, the Northern Sea Route or

17554-489: Was the Battle of the Delta , the Ancient Egyptians defeated the Sea Peoples in a sea battle c.  1175 BC . As recorded on the temple walls of the mortuary temple of pharaoh Ramesses III at Medinet Habu , this repulsed a major sea invasion near the shores of the eastern Nile Delta using a naval ambush and archers firing from both ships and shore. Assyrian reliefs from the 8th century BC show Phoenician fighting ships, with two levels of oars, fighting men on

17688-399: Was the jong . The jongs were large transport ships which could carry 100–2000 tons of cargo and 50–1000 people, 28.99–88.56 meter in length. The exact number of jong fielded by Majapahit is unknown, but the largest number of jong deployed in an expedition is about 400 jongs, when Majapahit attacked Pasai, in 1350. In this era, even to the 17th century, the Nusantaran naval soldiers fought on

17822-430: Was the product of a single mind or even of a generation; most likely the period of evolution and experimentation was simply not recorded by history. After some initial battles while subjugating the Greeks of the Ionian coast, the Persians determined to invade Greece proper. Themistocles of Athens estimated that the Greeks would be outnumbered by the Persians on land, but that Athens could protect itself by building

17956-429: Was written in the Han dynasty that the people of the Warring States era had employed chuan ge ships (dagger-axe ships, or halberd ships), thought to be a simple description of ships manned by marines carrying dagger-axe halberds as personal weapons. The 3rd-century writer Zhang Yan asserted that the people of the Warring States period named the boats this way because halberd blades were actually fixed and attached to
