In 2010–12, shipping companies, especially from Ukraine, claimed that their vessels suffered from "regular pirate attacks " on
7038-555: 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,
7140-508: 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
7242-477: The gorge) by the Iron Gate II Hydroelectric Power Station . On 13 April 2006, a record peak discharge at Iron Gate Dam reached 15,400 m /s (540,000 cu ft/s). There are three artificial waterways built on the Danube: the Danube-Tisa-Danube Canal (DTD) in the Banat and Bačka regions ( Vojvodina , northern province of Serbia); the 64 km (40 mi) Danube-Black Sea Canal , between Cernavodă and Constanța (Romania) finished in 1984, shortens
7344-521: The hero Achilles was buried (to this day, one of the mouths of the Danube is called Chilia). Old Romanian folk songs recount a white monastery on a white island with nine priests. Between the late 14th and late 19th centuries, the Ottoman Empire competed first with the Kingdom of Serbia , Second Bulgarian Empire , Kingdom of Hungary , Principality of Wallachia , Principality of Moldavia and later with
7446-483: The highest flow, an average of 8,500 L/s (300 cu ft/s), north of Lake Constance —thus feeding the Rhine. The European Water Divide applies only for those waters that pass beyond this point, and only during the days of the year when the Danube carries enough water to survive the sinkholes in the Donauversickerung. Since such large volumes of underground water erode much of the surrounding limestone, it
7548-473: 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
7650-431: The latter was further borrowed into Romanian as a regionalism ( Turlă ). The Thraco- Phrygian name was Matoas , "the bringer of luck". The Middle Mongolian name for the Danube was transliterated as Tho-na in 1829 by Jean-Pierre Abel-Rémusat . The modern languages spoken in the Danube basin all use names derived from the Latin name Danubius : Danube is an Old European river name derived from
7752-537: 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
7854-679: The north, deep fjords and sheer cliffs mark much of its Norwegian and Scottish coastlines respectively, whereas in 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
7956-520: The northern barbarian Thracian and Illyrian tribes by advancing from Macedonia as far as the Danube in 336 BCE. Under the Romans, the Danube formed the border of the Empire with the tribes to the north almost from its source to its mouth. At the same time, it was a route for the transport of troops and the supply of settlements downstream. From 37 CE to the reign of the Emperor Valentinian I (364–375)
8058-492: 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
8160-463: The river are four national capitals: Vienna , Bratislava , Budapest , and Belgrade . Its drainage basin amounts to 817,000 km (315,000 sq mi) and extends into nine more countries. The Danube's longest headstream Breg rises in Furtwangen im Schwarzwald , while the river carries its name from its source confluence in the palace park in Donaueschingen onwards. Since ancient times,
8262-567: The river has been part of a trans-European waterway from Rotterdam on the North Sea to Sulina on the Black Sea, a distance of 3,500 km (2,200 mi). In 1994 the Danube was declared one of ten Pan-European transport corridors , routes in Central and Eastern Europe that required major investment over the following ten to fifteen years. The amount of goods transported on the Danube increased to about 100 million tons in 1987. In 1999, transport on
8364-679: The river was made difficult by the NATO bombing of three bridges in Serbia during the Kosovo War . Clearance of the resulting debris was completed in 2002, and a temporary pontoon bridge that hampered navigation was removed in 2005. At the Iron Gate , the Danube flows through a gorge that forms part of the boundary between Serbia and Romania; it contains the Iron Gate I Hydroelectric Power Station dam, followed at about 60 km (37 mi) downstream (outside
8466-636: The river. The Danube Delta ( Romanian : Delta Dunării pronounced [ˈdelta ˈdunərij] ; Ukrainian : Дельта Дунаю , romanized : Del'ta Dunayu ) is the largest river delta in the European Union . The greater part of the Danube Delta lies in Romania (Tulcea county), while its northern part, on the left bank of the Chilia arm, is situated in Ukraine (Odesa Oblast). The approximate surface
8568-503: The river. Members include representatives from Austria, Bulgaria, Croatia, Germany, Hungary, Moldova, Slovakia, Romania, Russia, Ukraine, and Serbia; it meets regularly twice a year. It also convenes groups of experts to consider items provided for in the commission's working plans. The commission dates to the Paris Conferences of 1856 and 1921, which established for the first time an international regime to safeguard free navigation on

8772-639: The same word means "river". The Finnish word for Danube is Tonava , which is most likely derived from the name of the river in German , Donau . Its Sámi name Deatnu means "Great River". It is possible that dānu in Scythian as in Avestan was a generic word for "river": Dnieper and Dniestr , from Danapris and Danastius , are presumed to continue Scythian * dānu apara "far river" and * dānu nazdya- "near river", respectively. In Latin,
8874-463: 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
8976-413: 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
9078-629: The sixth-to-third millennium BCE Vinča culture (Vinča, Serbia), are sited along the Danube. The third millennium BCE Vučedol culture (from the Vučedol site near Vukovar , Croatia ) is famous for its ceramics. Darius the Great , king of Persia , crossed the river in the late 6th century BCE to invade European Scythia and to subdue the Scythians . Alexander the Great defeated the Triballian king Syrmus and
9180-464: 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
9282-514: The suffix -ouwe "wetland". Romanian differs from other surrounding languages in designating the river with a feminine term, Dunărea ( IPA: [ˈdunəre̯a] ). This form was not inherited from Latin, although Romanian is a Romance language. To explain the loss of the Latin name, scholars who suppose that Romanian developed near the large river propose that the Romanian name descends from
9384-490: The total area of the Danube Delta reaches 5,165 km (1,994 sq mi). The Danube Delta is also the best-preserved river delta in Europe, a UNESCO World Heritage Site (since 1991) and a Ramsar Site . Its lakes and marshes support 45 freshwater fish species. Its wetlands support vast flocks of migratory birds of over 300 species, including the endangered pygmy cormorant ( Phalacrocorax pygmaeus ). These are threatened by rival canalization and drainage schemes such as
9486-846: 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
9588-554: 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
9690-406: 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
9792-504: The world. Ordered from the source to the mouth they are: The Danube is navigable by ocean ships from the Black Sea to Brăila in Romania (the maritime river sector), and further on by river ships to Kelheim , Bavaria , Germany; smaller craft can navigate further upstream to Ulm , Württemberg , Germany. About 60 of its tributaries are also navigable. Since the completion of the German Rhine–Main–Danube Canal in 1992,
9894-575: 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
9996-560: 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
10098-616: 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
10200-693: Was known to the ancient Greeks as the Istros ( Ἴστρος ) from a root possibly also encountered in the ancient name of the Dniester ( Danaster in Latin, Tiras in Greek) and akin to Iranic turos 'swift' and Sanskrit iṣiras ( इषिरस् ) 'swift', from the PIE * isro- , * sreu 'to flow'. In the Middle Ages, the Greek Tiras was borrowed into Italian as Tyrlo and into Turkic languages as Tyrla ;
10302-621: Was much larger than today's Danube, can still be seen in (now waterless) canyons in today's landscape of the Swabian Alb . After the Upper Rhine valley had been eroded, most waters from the Alps changed their direction and began feeding the Rhine. Today's upper Danube is thus an underfit stream . Since the Swabian Alb is largely shaped of porous limestone , and since the Rhine's level is much lower than
10404-450: Was once a frontier of the Roman Empire . In the 21st century, it connects ten European countries, running through their territories or marking a border. Originating in Germany , the Danube flows southeast for 2,850 km (1,770 mi), passing through or bordering Austria , Slovakia , Hungary , Croatia , Serbia , Romania , Bulgaria , Moldova , and Ukraine .
