89-470: The Old Man House was the largest winter longhouse in what is now the U.S. state of Washington , once standing on the shore of Puget Sound . It was the center of the Suquamish village of dxʷsəq̓ʷəb on Agate Pass , just south of the present-day town of Suquamish . At one time, it was home to the famous Suquamish chiefs Kitsap and Seattle (who was also half Duwamish ). The Lushootseed name of

178-557: A Tuath . The North Sea has provided waterway access for commerce and conquest. Many areas have access to the North Sea because of its long coastline and the European rivers that empty it. There is little documentary evidence concerning the North Sea before the Roman conquest of Britain in 43 CE, however, archaeological evidence reveals the diffusion of cultures and technologies from across or along

267-433: A central communal hearth and a place for dancing. There are also places for religious and ritual objects and activities. In the adjoining room the women and their small children as well as unmarried daughters sleep, usually in compartments divided into families. The platform on the back is used by the women for their everyday activities. Visiting women usually enter the house here. The Mnong and Rade of Vietnam also have

356-704: A challenge to their dominance of the North Sea until the 20th century. Tensions in the North Sea were again heightened in 1904 by the Dogger Bank incident . During the Russo-Japanese War , several ships of the Russian Baltic Fleet, which was on its way to the Far East, mistook British fishing boats for Japanese ships and fired on them, and then upon each other, near the Dogger Bank, nearly causing Britain to enter

445-415: A covered gallery. The inside is divided into two rooms, one behind the other. On the back there is another platform. The whole building is raised on short stilts about half a metre off the ground. The front platform is used for general activities while the covered gallery is the favorite place for the men to host guests, and where the men usually sleep. The following first room is entered by a door and contains

534-510: A rich source of energy resources, including wind and wave power . The North Sea has featured prominently in geopolitical and military affairs, particularly in Northern Europe , from the Middle Ages to the modern era. It was also important globally through the power northern Europeans projected worldwide during much of the Middle Ages and into the modern era. The North Sea was the centre of

623-694: A second storey, stairways, a chimney with bread oven, an outshut (pantry/larder/dairy which was only accessible from inside the house), glazed windows, lime screed floors and at least some decorative plasterwork. Other European longhouse types include the northwest England type in Cumbria , the Scottish longhouse, " blackhouse " or taighean-dubha, and the Scandinavian or Viking Langhus/Långhus and mead hall . The Western French longhouse or maison longue from Lower Brittany , Normandy , Mayenne , Anjou (also in

712-403: A single-story building, one room deep, laid out as two crucked bays a cross passage and two crucked bays. As glass was not available until the middle of the 16th century, they were oriented loosely East West with openings (for a door and latticed unglazed windows) only in the south wall to provide the maximum shelter from the worst weather and catch the sun. They are often dug into the hillside,

801-553: A tradition of building longhouses ( Vietnamese : nhà dài ) that may be 30 to 40 metres (98 to 131 ft) long. In contrast to the jungle versions of Borneo these sport shorter stilts and seem to use a veranda in front of a short (gable) side as main entrance. The Rana Tharu is an ethnic group indigenous to the western Terai of Nepal . Most of them prefer living in longhouses called Badaghar with big families of many generations, sometimes 40–50 people. All household members pool their labor force, contribute their income, share

890-699: A vast merchant marine, a large fishing fleet, powerful navy, and sophisticated financial markets made the Dutch the ascendant power in the North Sea, to be challenged by an ambitious England. This rivalry led to the first three Anglo-Dutch Wars between 1652 and 1673, which ended with Dutch victories. After the Glorious Revolution in 1688, the Dutch prince William ascended to the English throne. With unified leadership, commercial, military, and political power began to shift from Amsterdam to London. The British did not face

979-522: A volume of 54,000 cubic kilometres (13,000 cu mi). Around the edges of the North Sea are sizeable islands and archipelagos , including Shetland , Orkney , and the Frisian Islands . The North Sea receives freshwater from a number of European continental watersheds, as well as the British Isles . A large part of the European drainage basin empties into the North Sea, including water from

Other areas which are less deep are Cleaver Bank , Fisher Bank and Noordhinder Bank . The International Hydrographic Organization defines the limits of the North Sea as follows: On the Southwest. A line joining

1246-518: Is also home to marine mammals. Common seals , grey seals , and harbour porpoises can be found along the coasts, at marine installations, and on islands. The very northern North Sea islands such as the Shetland Islands are occasionally home to a larger variety of pinnipeds including bearded , harp , hooded and ringed seals , and even walrus . North Sea cetaceans include various porpoise , dolphin and whale species. Plant species in

1335-742: Is bounded by the Orkney Islands and east coast of Great Britain to the west and the northern and central European mainland to the east and south, including Norway , Denmark , Germany , the Netherlands , Belgium , and France . In the southwest, beyond the Straits of Dover , the North Sea becomes the English Channel connecting to the Atlantic Ocean. In the east, it connects to the Baltic Sea via

1424-479: Is designed and built as a standing tree with branches to the right and left with the front part facing the sunrise while the back faces the sunset. The longhouse building acts as the normal accommodation and a house of worship for religious activities. The entry could double as a canoe dock. Cooling air could circulate underneath the raised floor of the dwelling, and the elevated living areas were more likely to catch above-ground breezes. Livestock could shelter underneath

1513-490: Is known as the Tŷ Hir , are often typified by the use of cruck construction. It is built along a slope, and a single passage gives access to both human and animal shelter under a single roof. There are dozens of pre-1600 longhouses remaining on Exmoor and the surrounding area. Some can be dated using dendrochronology to before 1400, but sites can be much older and have names with a Saxon origin. Longhouses on Exmoor are typically

1602-676: Is recorded to have killed more than 100,000 people. In 1362, the Second Marcellus Flood , also known as the Grote Manndrenke , hit the entire southern coast of the North Sea. Chronicles of the time again record more than 100,000 deaths, large parts of the coast were lost permanently to the sea, including the now legendary lost city of Rungholt . In the 20th century, the North Sea flood of 1953 flooded several nations' coasts and cost more than 2,000 lives. 315 citizens of Hamburg died in

1691-526: Is the Norwegian trench , which extends parallel to the Norwegian shoreline from Oslo to an area north of Bergen . It is between 20 and 30 kilometres (12 and 19 mi) wide and has a maximum depth of 725 metres (2,379 ft). The Dogger Bank , a vast moraine , or accumulation of unconsolidated glacial debris, rises to a mere 15 to 30 m (50 to 100 ft) below the surface. This feature has produced

1780-510: The Baltic Sea . The largest and most important rivers flowing into the North Sea are the Elbe and the Rhine – Meuse . Around 185 million people live in the catchment area of the rivers discharging into the North Sea encompassing some highly industrialized areas. For the most part, the sea lies on the European continental shelf with a mean depth of 90 metres (300 ft). The only exception

1869-521: The Battle of Heligoland Bight , the Battle of the Dogger Bank , and the Battle of Jutland . World War I also brought the first extensive use of submarine warfare , and a number of submarine actions occurred in the North Sea. The Second World War also saw action in the North Sea, though it was restricted more to aircraft reconnaissance and action by fighter/bomber aircraft, submarines and smaller vessels such as minesweepers and torpedo boats .

1958-599: The Cantal , Lozère and the Pyrenees Ariège ), is very similar to the western British type with shared livestock quarters and central drain. The Old Frisian longhouse or Langhuis developed into the Frisian farmhouse which probably influenced the development of the Gulf house (German: Gulfhaus ), which spread along the North Sea coast to the east and north. Further developments of

2047-609: The Dayak , live traditionally in buildings known as Lamin House or longhouses: rumah betang in Indonesia (specifically the western parts of Borneo) and rumah panjang in Malay. Common to most of these is that they are built raised off the ground on stilts and are divided into a more or less public area along one side and a row of private living quarters lined along the other side. This seems to have been

2136-516: The English Channel was triggered by the earthquake, which in turn caused a tsunami. The tsunami triggered by the 1755 Lisbon earthquake reached Holland, although the waves had lost their destructive power. The largest earthquake ever recorded in the United Kingdom was the 1931 Dogger Bank earthquake , which measured 6.1 on the Richter magnitude scale and caused a small tsunami that flooded parts of

2225-625: The European continental shelf , it connects to the Atlantic Ocean through the English Channel in the south and the Norwegian Sea in the north. It is more than 970 kilometres (600 mi) long and 580 kilometres (360 mi) wide, covering 570,000 square kilometres (220,000 sq mi). It hosts key north European shipping lanes and is a major fishery . The coast is a popular destination for recreation and tourism in bordering countries, and

2314-508: The Last Glacial Maximum when the sea began to flood the European continental shelf. In 2006 a bone fragment was found while drilling for oil in the North Sea. Analysis indicated that it was a Plateosaurus from 199 to 216 million years ago. This was the deepest dinosaur fossil ever found and the first find for Norway. Copepods and other zooplankton are plentiful in the North Sea. These tiny organisms are crucial elements of

2403-954: The Latin names Mare Germanicum and Oceanus Germanicus , and these persisted in use until the First World War. Other common names in use for long periods were the Latin terms Mare Frisicum , as well as the English equivalent, "Frisian Sea". The modern names of the sea in the other local languages are: Danish : Vesterhavet , lit.   'West Sea' [ˈvestɐˌhɛˀvð̩] or Nordsøen [ˈnoɐ̯ˌsøˀn̩] , Dutch : Noordzee , Dutch Low Saxon : Noordzee , French : Mer du Nord , West Frisian : Noardsee , German : Nordsee , Low German : Noordsee , North Frisian : Weestsiie , lit.   'West Sea', Swedish : Nordsjön , Bokmål : Nordsjøen [ˈnûːrˌʂøːn] , Nynorsk : Nordsjøen , Scots : North Sea and Scottish Gaelic : An Cuan

2492-468: The Mentawai Islands some 130 kilometres (81 mi) to the west off the coast of Sumatra ( Sumatera ), Indonesia is also described as a longhouse on stilts. Some five to ten families may live in each, but they are organized differently inside from those on Borneo. From front to back, such a house, called an "uma", regularly consists of an open platform serving as the main entrance place, followed by

2581-465: The North Sea flood of 1962 . Though rare, the North Sea has been the site of a number of historically documented tsunamis . The Storegga Slides were a series of underwater landslides, in which a piece of the Norwegian continental shelf slid into the Norwegian Sea. The immense landslips occurred between 8150 BCE and 6000 BCE, and caused a tsunami up to 20 metres (66 ft) high that swept through

2670-985: The Phare de Walde (Walde Lighthouse, in France, 50°59'37"N, 1°54'53"E) and Leathercoat Point (England, 51°10'01.4"N 1°24'07.8"). northeast of Dover. On the Northwest. From Dunnet Head (58°40'20"N, 3°22'30"W) in Scotland to Tor Ness (58°47'N) in the Island of Hoy , thence through this island to the Kame of Hoy (58°55'N) on to Breck Ness on Mainland (58°58'N) through this island to Costa Head (3°14'W) and Inga Ness (59'17'N) in Westray through Westray, to Bow Head, across to Mull Head (North point of Papa Westray ) and on to Seal Skerry (North point of North Ronaldsay ) and thence to Horse Island (South point of

2759-734: The Point Elliott Treaty was signed in 1855, becoming the Port Madison Indian Reservation . The longhouse was burned down by the U.S. government in 1870 under the orders of William DeShaw, the Indian agent at the reservation. Despite being a close friend of Chief Seattle, DeShaw ordered the Old Man House's destruction after Seattle's death to force the Suquamish to build single-family residences instead of communal dwellings. After it

3026-508: The Tucano people of Colombia and northwest Brazil traditionally combine a household in a single long house. The Xingu peoples of central Brazil build a series of longhouses in circular formations forming round villages. The ancient Tupi people of the Brazilian coast used to do this as well. The Yanomami people of Brazil and Venezuela build a round hut with a thatched roof that has a hole in

3115-610: The Vikings' rise . The Hanseatic League , the Dutch Republic , and the British each sought to gain command of the North Sea and access to the world's markets and resources. As Germany's only outlet to the ocean, the North Sea was strategically important through both world wars. The coast has diverse geology and geography. In the north, deep fjords and sheer cliffs mark much of its Norwegian and Scottish coastlines respectively, whereas in

3204-463: The food chain supporting many species of fish. Over 230 species of fish live in the North Sea. Cod , haddock , whiting , saithe , plaice , sole , mackerel , herring , pouting , sprat , and sandeel are all very common and are fished commercially. Due to the various depths of the North Sea trenches and differences in salinity, temperature, and water movement, some fish such as blue-mouth redfish and rabbitfish reside only in small areas of

3293-688: The indigenous peoples of the Pacific Northwest Coast . The longhouses inhabited by the Iroquois were wood boards/bark-covered structures of standardized design "in the shape of an arbor" about 6 to 7 metres (20 to 23 ft) wide providing shelter for several related families. The longhouse had a 3-metre-wide (9.8 ft) central aisle and 2-metre-wide (6.6 ft) compartments, about 6 to 7 metres (20 to 23 ft) long, down each side. The end compartments were usually used for storage. Hearths were spaced about 6 to 7 metres (20 to 23 ft) apart down

3382-535: The littoral is low and marshy. The east coast and south-east of the North Sea ( Wadden Sea ) have coastlines that are mainly sandy and straight owing to longshore drift , particularly along Belgium and Denmark. The southern coastal areas were originally flood plains and swampy land. In areas especially vulnerable to storm surges, people settled behind elevated levees and on natural areas of high ground such as spits and geestland . As early as 500 BC, people were constructing artificial dwelling hills higher than

3471-729: The 13th century the Hanseatic League , though centred on the Baltic Sea , started to control most of the trade through important members and outposts on the North Sea. The League lost its dominance in the 16th century, as neighbouring states took control of former Hanseatic cities and outposts. Their internal conflict prevented effective cooperation and defence. As the League lost control of its maritime cities, new trade routes emerged that provided Europe with Asian, American, and African goods. The 17th century Dutch Golden Age saw Dutch maritime power at its zenith. Important overseas colonies,

3560-566: The British coast. Shallow epicontinental seas like the current North Sea have since long existed on the European continental shelf . The rifting that formed the northern part of the Atlantic Ocean during the Jurassic and Cretaceous periods, from about 150  million years ago , caused tectonic uplift in the British Isles. Since then, a shallow sea has almost continuously existed between

3649-829: The Germanic longhouse during the Middle Ages were the Low German house in northern and especially northwestern Germany and its northern neighbour, the Geestharden house in Jutland including Schleswig , with its variant, the Frisian house. With these house types the wooden posts originally rammed into the ground were replaced by posts supported on a base. The large and well-supported attic enabled large quantities of hay or grain to be stored in dry conditions. This development may have been driven because

3738-501: The Middle Ages through the 15th century, the northern European coastal ports exported domestic goods, dyes, linen, salt, metal goods and wine. The Scandinavian and Baltic areas shipped grain, fish, naval necessities, and timber. In turn, the North Sea countries imported high-grade cloths, spices, and fruits from the Mediterranean region. Commerce during this era was mainly conducted by maritime trade due to underdeveloped roadways. In

3827-480: The Netherlands. The North Sea Floods of 1953 and 1962 were the impetus for further raising of the dikes as well as the shortening of the coast line so as to present as little surface area as possible to the punishment of the sea and the storms. Currently, 27% of the Netherlands is below sea level protected by dikes, dunes, and beach flats. Coastal management today consists of several levels. The dike slope reduces

3916-900: The North Sea are home to nature reserves including the Ythan Estuary , Fowlsheugh Nature Preserve, and Farne Islands in the UK and the Wadden Sea National Parks in Denmark, Germany and the Netherlands. These locations provide breeding habitat for dozens of bird species. Tens of millions of birds make use of the North Sea for breeding, feeding, or migratory stopovers every year. Populations of black-legged kittiwakes , Atlantic puffins , northern gannets , northern fulmars , and species of petrels , seaducks , loons (divers), cormorants , gulls , auks , and terns , and many other seabirds make these coasts popular for birdwatching . The North Sea

On the East. The Western limit of the Skagerrak [A line joining Hanstholm ( 57°07′N 8°36′E  /  57.117°N 8.600°E  / 57.117; 8.600 ) and the Naze ( Lindesnes , 58°N 7°E  /  58°N 7°E  / 58; 7 )]. The average temperature

4094-402: The North Sea during the Migration Period . They made successive invasions of the island from what is now the Netherlands, Denmark, and Germany. The Viking Age began in 793 with the attack on Lindisfarne ; for the next quarter-millennium, the Vikings ruled the North Sea. In their superior longships , they raided, traded, and established colonies and outposts along the coasts of the sea. From

4183-554: The North Sea include species of wrack , among them bladder wrack , knotted wrack , and serrated wrack. Algae , macroalgal, and kelp , such as oarweed and laminaria hyperboria, and species of maerl are found as well. Eelgrass , formerly common in the entirety of the Wadden Sea, was nearly wiped out in the 20th century by a disease. Similarly, sea grass used to coat huge tracts of ocean floor, but have been damaged by trawling and dredging have diminished its habitat and prevented its return. Invasive Japanese seaweed has spread along

4272-445: The North Sea to Great Britain and Scandinavia and reliance by some prehistoric cultures on fishing, whaling, and seaborne trade on the North Sea. The Romans established organised ports in Britain, which increased shipping and began sustained trade the diffusion of cultures and technologies from across or along the North Sea to Great Britain and Scandinavia and reliance by some prehistoric cultures on fishing, whaling, and seaborne trade on

4361-416: The North Sea until the 20th century, when numbers declined due to overfishing . Other factors like the introduction of non-indigenous species , industrial and agricultural pollution , trawling and dredging , human-induced eutrophication , construction on coastal breeding and feeding grounds, sand and gravel extraction, offshore construction , and heavy shipping traffic have also contributed to

4450-420: The North Sea, having the greatest effect on Scotland and the Faeroe Islands . The Dover Straits earthquake of 1580 is among the first recorded earthquakes in the North Sea measuring between 5.6 and 5.9 on the Richter scale. This event caused extensive damage in Calais both through its tremors and possibly triggered a tsunami , though this has never been confirmed. The theory is a vast underwater landslide in

4539-399: The North Sea. Crustaceans are also commonly found throughout the sea. Norway lobster , deep-water prawns , and brown shrimp are all commercially fished, but other species of lobster , shrimp , oyster , mussels and clams all live in the North Sea. Recently non-indigenous species have become established including the Pacific oyster and Atlantic jackknife clam . The coasts of

The Romans established organised ports in Britain, which increased shipping and began sustained trade and many Scandinavian tribes participated in raids and wars against the Romans and Roman coinage and manufacturing were important trade goods. When the Romans abandoned Britain in 410, the Germanic Angles , Frisians , Saxons , and Jutes began the next great migration across

4717-448: The North Sea. The wave continues to travel northward in the Atlantic Ocean, and once past the northern tip of Great Britain, the Kelvin wave turns east and south and once again enters the North Sea. The eastern and western coasts of the North Sea are jagged, formed by glaciers during the ice ages . The coastlines along the southernmost part are covered with the remains of deposited glacial sediment. The Norwegian mountains plunge into

Storm surges are caused by changes in barometric pressure combined with strong wind created wave action . The first recorded storm tide flood was the Julianenflut , on 17 February 1164. In its wake, the Jadebusen , (a bay on the coast of Germany), began to form. A storm tide in 1228

5162-435: The decline. For example, a resident orca pod was lost in the 1960s, presumably due to the peak in PCB pollution in this time period. The OSPAR commission manages the OSPAR convention to counteract the harmful effects of human activity on wildlife in the North Sea, preserve endangered species , and provide environmental protection. All North Sea border states are signatories of the MARPOL 73/78 Accords, which preserve

5251-654: The earliest form of permanent structure in many cultures. Types include the Neolithic long house of Europe, the Norman Medieval Longhouses that evolved in Western Britain ( Tŷ Hir ) and Northern France ( Longère ), and the various types of longhouse built by different cultures among the indigenous peoples of the Americas . The Neolithic long house type was introduced with the first farmers of Central and Western Europe around 5000 BCE, 7,000 years ago. These were farming settlements built in groups of six to twelve longhouses; they were home to large extended families and kin. The Germanic cattle-farmer longhouses emerged along

5340-555: The energy of the incoming sea, so that the dike itself does not receive the full impact. Dikes that lie directly on the sea are especially reinforced. The dikes have, over the years, been repeatedly raised, sometimes up to 9 metres (30 ft) and have been made flatter to better reduce wave erosion. Where the dunes are sufficient to protect the land behind them from the sea, these dunes are planted with beach grass ( Ammophila arenaria ) to protect them from erosion by wind, water, and foot traffic. Storm surges threaten, in particular,

5518-508: The finest fishing location of the North Sea. The Long Forties and the Broad Fourteens are large areas with roughly uniform depth in fathoms (forty fathoms and fourteen fathoms or 73 and 26 m or 240 and 85 ft deep, respectively). These great banks and others make the North Sea particularly hazardous to navigate, which has been alleviated by the implementation of satellite navigation systems . The Devil's Hole lies 320 kilometres (200 mi) east of Dundee , Scotland. The feature

5607-420: The highest variability where there is fresh water inflow, such as at the Rhine and Elbe estuaries, the Baltic Sea exit and along the coast of Norway. The main pattern to the flow of water in the North Sea is an anti-clockwise rotation along the edges. The North Sea is an arm of the Atlantic Ocean receiving the majority of ocean current from the northwest opening, and a lesser portion of warm current from

5696-443: The house and livestock in the other, but would only be needed for a couple of months at most in the winter. There was a fire pit, sometimes with a stone reredos (as in Hendre’r-ywydd Uchaf Farmhouse, Denbighshire), behind which the smoke rose to the eaves and passed through the thatch. As skills and wealth increased, after 1500 many had built in settles, most by 1700 would have been adapted and have: separate buildings for livestock,

5785-466: The inner partitions and arrangements are somewhat obscure. The size of the buildings and their placement within the settlements may point to buildings for the nobles of their society or some sort of community or religious buildings. In Igeum-dong , an excavation site in South Korea , the large longhouses, 29 and 26 metres long, are situated between the megalithic cemetery and the rest of the settlement. The longhouse may be an old building tradition among

5874-476: The longhouses for greater protection from predators and the elements. In fact, chickens coops were hung from the main room structure for easy feeding. Old longhouses in Asia were made of tree trunks as structure members, long leaves as the roof cover, split bamboo or small tree trunks as the flooring and tree bark as the wall coverings. In the past, longhouses were primarily made out of timber sourced from trees such as Eusideroxylon zwageri (Bornean ironwood ) so

5963-418: The longhouses were able to stand firm and durable. In modern times many of the older longhouses have been replaced with buildings using more modern materials, like brick or cement, but of similar design. Many place names in Borneo have "Long" in their name (which means river) and most of these are or once were longhouses. A traditional house type of the Sakuddei people, on the island of Siberut , part of

6052-431: The lower parts of the walls are formed from rough stone in mud pointing with cob above, as before the 17th century lime cement was virtually unknown.The floors were not made a true level. Livestock used the lower end. A hole is often provided in the base of the end wall for mucking out. The cross passage (often misnamed as a breezeway did not pass right through the building) establishes distinct areas for people in one half of

6141-431: The marine environment by preventing pollution from ships. Germany, Denmark, and the Netherlands also have a trilateral agreement for the protection of the Wadden Sea , or mudflats , which run along the coasts of the three countries on the southern edge of the North Sea. The North Sea has had various names throughout history. One of the earliest recorded names was Septentrionalis Oceanus , or "Northern Ocean", which

6230-447: The middle, called shabono , which could be considered a sort of longhouse. In Daepyeong , an archaeological site of the Mumun pottery period in Korea , longhouses have been found that date to circa 1100–850 BC. Their layout seems to be similar to those of the Iroquois. In these, several fireplaces were arranged along the longitudinal axis of the building. Later, the ancient Koreans started raising their buildings on stilts, so that

6319-422: The new naval shipyards at Bremerton . The destruction of the longhouse was intended to encourage the Suquamish to spread out across their reservation and take up farming. The village site had to be moved, and the tribe lost much of its water access. The fortifications were never built, and the land purchased by the military was eventually sold in 1937 to a private developer and subdivided for vacation homes. In 1950,

6408-640: The people of Austronesian origin or intensive contact. The Austronesian language group seems to have spread to southeast Asia and the Pacific islands as well as Madagascar from the island of Taiwan . Groups like the Siraya of ancient Taiwan built longhouses and practiced head hunting, as did, for example the later Dayaks of Borneo. Many of the inhabitants of the Southeast Asian island of Borneo (now Indonesian Kalimantan , East Malaysia and Brunei Darussalam ),

6497-492: The prevailing flood levels. It was only around the beginning of the High Middle Ages , in 1200 AD, that inhabitants began to connect single ring dikes into a dike line along the entire coast, thereby turning amphibious regions between the land and the sea into permanent solid ground. The modern form of the dikes supplemented by overflow and lateral diversion channels, began to appear in the 17th and 18th centuries, built in

6586-463: The sea creating deep fjords and archipelagos . South of Stavanger, the coast softens, the islands become fewer. The eastern Scottish coast is similar, though less severe than Norway. From north east of England , the cliffs become lower and are composed of less resistant moraine , which erodes more easily, so that the coasts have more rounded contours. In the Netherlands, Belgium and in East Anglia

6675-413: The shores of the sea clogging harbours and inlets and has become a nuisance. Due to the heavy human populations and high level of industrialization along its shores, the wildlife of the North Sea has suffered from pollution, overhunting, and overfishing. Flamingos and pelicans were once found along the southern shores of the North Sea, but became extinct over the second millennium. Walruses frequented

6764-609: The site upon which the house was located is dxʷsəq̓ʷəb , meaning "clear salt water," and is the origin of the name of the Suquamish people: dxʷsəq̓ʷəbš (which means "people of the clear salt water"). The name "Old Man House" comes from the Chinook Jargon word "oleman" meaning "old, worn out," but also meaning "from the old times". "House" in Chinook Jargon refers to any kind of building, or even to individual rooms within them. Archeological investigations have revealed that

6853-464: The smaller opening at the English Channel. These tidal currents leave along the Norwegian coast. Surface and deep water currents may move in different directions. Low salinity surface coastal waters move offshore, and deeper, denser high salinity waters move inshore. The North Sea located on the continental shelf has different waves from those in deep ocean water. The wave speeds are diminished and

6942-557: The south, the coast consists mainly of sandy beaches, estuaries of long rivers and wide mudflats . Due to the dense population, heavy industrialisation , and intense use of the sea and the area surrounding it, various environmental issues affect the sea's ecosystems. Adverse environmental issues – commonly including overfishing , industrial and agricultural runoff , dredging , and dumping, among others – have led to several efforts to prevent degradation and to safeguard long-term economic benefits. The North Sea

7031-599: The southwestern North Sea coast in the third or fourth century BCE and may be the ancestors of several medieval house types such as the Scandinavian langhus ; the English, Welsh, and Scottish longhouse variants; and the German and Dutch Low German house . The longhouse is a traditional form of shelter. Some of the medieval longhouse types of Europe that have survived are the following: The Western Brittonic " Dartmoor longhouse " variants in Devon , Cornwall , and Wales , where it

7120-790: The uplands of the Fennoscandian Shield and the British Isles. This precursor of the current North Sea has grown and shrunk with the rise and fall of the eustatic sea level during geologic time. Sometimes it was connected with other shallow seas, such as the sea above the Paris Basin to the south-west, the Paratethys Sea to the south-east, or the Tethys Ocean to the south. During the Late Cretaceous, about 85  million years ago , all of modern mainland Europe except for Scandinavia

7209-421: The village site was occupied for at least 2000 years. Accounts vary as to when the longhouse itself was constructed; many sources indicate it was built in the late 18th or early 19th century, but it might have been built earlier. Reports of the longhouse's size also vary, putting its length between 600 and 1000 feet (approximately 200–300 m). The lands around Old Man House were retained by the Suquamish tribe after

7298-554: The war on the side of Japan. During the First World War , Great Britain's Grand Fleet and Germany's Kaiserliche Marine faced each other in the North Sea, which became the main theatre of the war for surface action. Britain's larger fleet and North Sea Mine Barrage were able to establish an effective blockade for most of the war, which restricted the Central Powers ' access to many crucial resources. Major battles included

7387-406: The wave amplitudes are increased. In the North Sea there are two amphidromic systems and a third incomplete amphidromic system. In the North Sea the average tide difference in wave amplitude is between zero and eight metres (26 ft). The Kelvin tide of the Atlantic Ocean is a semidiurnal wave that travels northward. Some of the energy from this wave travels through the English Channel into

7476-465: The way of building best accustomed to life in the jungle in the past, as otherwise hardly related people have come to build their dwellings in similar ways. One may observe similarities to South American jungle villages also living in large single structures. They are raised and built over a hill, flooding presents little inconvenience and the height acts as defence against enemy attacks. Some longhouses are quite large; up to 1152m. The entire architecture

7565-535: The weather became wetter over time. Good examples of these houses have been preserved, some dating back to the 16th century. The longhouse was 50 to 60 feet long. In North America two groups of longhouses emerged: the Native American/First Nations longhouse of the tribes usually connected with the Iroquois (Haudenosaunee) in the northeast, and a similarly shaped structure which arose independently among

7654-519: Was a scattering of islands. By the Early Oligocene , 34 to 28 million years ago , the emergence of Western and Central Europe had almost completely separated the North Sea from the Tethys Ocean, which gradually shrank to become the Mediterranean as Southern Europe and South West Asia became dry land. The North Sea was cut off from the English Channel by a narrow land bridge until that

7743-560: Was breached by at least two catastrophic floods between 450,000 and 180,000 years ago. Since the start of the Quaternary period about 2.6  million years ago , the eustatic sea level has fallen during each glacial period and then risen again. Every time the ice sheet reached its greatest extent, the North Sea became almost completely dry, the dry landmass being known as Doggerland , whose northern regions were themselves known to have been glaciated. The present-day coastline formed after

7832-474: Was burned, however, the Suquamish rebuilt their village at the site and continued to live there, which led to DeShaw resigning from the Bureau of Indian Affairs. In 1886 the federal government divided the reservation into allotments which were assigned to individual Suquamish families. In 1904 the U.S. War Department acquired land along Agate Pass, including the site of Old Man House, to build fortifications to protect

7921-616: Was cited by Pliny . He also noted that the Cimbri called it Morimarusa – "Dead Sea". The name "North Sea" probably came into English, however, via the Dutch Noordzee , who named it thus either in contrast with the Zuiderzee ("South Sea"), located south of Frisia , or because the sea is generally to the north of the Netherlands. Before the adoption of "North Sea", the names used in English were "German Sea" or "German Ocean", referred to as
