The North Sea is a marginal, epeiric sea of the Atlantic Ocean on the European continental shelf. It is more than 600 miles (970 km) long and 350 miles (560 km) wide, with an area of around 222,000 square miles (570,000 km2). A large part of the European drainage basin empties into the North Sea including water from the [[Baltic|Baltic Sea]]. The North Sea connects with the rest of the Atlantic through the Dover Strait and the [[English Channel]] in the south and through the Norwegian Sea in the north.

Apart from the obvious boundaries formed by the coasts of the countries which border it, the North Sea is generally considered to be bounded by an imaginary line from Lindesnes, [[Norway]] to Hanstholm, [[Denmark]] running towards the Skagerrak. However, for statistical purposes, the Skagerrak and the Kattegat are sometimes included as part of the North Sea. The northern limit is less well-defined. Traditionally, an imaginary line is taken to run from northern [[Scotland]], by way of Shetland, to Ålesund in [[Norway]]. According to the Convention for the Protection of the Marine Environment of the North-East Atlantic of 1962 it runs further to the west and north from longitude 5° West and latitude 62° North, at the latitude of Geirangerfjord in [[Norway]].

{{Image right| North_Sea_Currents.gif| North Sea water flow}}
The tides are caused by the tide wave from the North Atlantic, as the North Sea itself is too small and too flat to have its own tides. Ebb and flow alternate in a cycle of 12.5 hours. The tide wave, owing to the ''Coriolis'' effect, flows around [[Scotland]] and then counter-clockwise along the English coast, reaching the German Bight some 12 hours after arriving in [[Scotland]]. In so doing, it runs around three amphidromic points: a central point lies shortly before the Straits of Dover. It is formed by the tide wave which is transported through the [[English Channel]]. It influences the tides in the narrow area in the Southern Bight between southern [England]] and the [[Netherlands]]. The other amphidromic system consists of two points close to each other, which form a tide wave. The two other points just off the coast of southern [[Norway]] and lying on a line between southern [[Denmark]] and the West Frisian Islands form one single area around which the tides flow. Its central point lies off the coast of [[Denmark]] at 55° 25' N, 5° 15' E.

As a result, the tidal range in southern [[Norway]] is less than half a metre (1.5 ft), but increases the further any given coast lies from the amphidromic point. Shallow coasts and the funnel effect of narrow straits increase the tidal range. The tidal range is at its greatest at The Wash on the English coast, where it reaches 6.80 m (22 ft). In shallow water areas, the real tidal range is strongly influenced by other factors, such as the position of the coast and the wind at any given moment or the action of storms. In river estuaries, high water levels can considerably amplify the effect of high tide.

The North Sea is a marginal, epeiric sea of the Atlantic Ocean on the European continental shelf. It is more than 600 miles (970 km) long and 350 miles (560 km) wide, with an area of around 222,000 square miles (570,000 km2). A large part of the European drainage basin empties into the North Sea including water from the Baltic Sea. The North Sea connects with the rest of the Atlantic through the Dover Strait and the English Channel in the south and through the Norwegian Sea in the north.

The North Sea averages about 100 m (325 ft) deep, with a maximum depth of 700 m (2300 ft) and in some areas shallows can be a mere 15 m deep.

For the most part, the sea lies on the European continental shelf. The only exception is the Norwegian trench, a narrow area of the northern North Sea off Norway. The North Sea is bounded by 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 south-west, the North Sea becomes the English Channel beyond the Straits of Dover. In the east, it connects to the Baltic Sea via the Skagerrak and Kattegat. In the north, it opens in a widening funnel shape to the Norwegian Sea, which lies in the very north-eastern part of the Atlantic.

Apart from the obvious boundaries formed by the coasts of the countries which border it, the North Sea is generally considered to be bounded by an imaginary line from Lindesnes, Norway to Hanstholm, Denmark running towards the Skagerrak. However, for statistical purposes, the Skagerrak and the Kattegat are sometimes included as part of the North Sea. The northern limit is less well-defined. Traditionally, an imaginary line is taken to run from northern Scotland, by way of Shetland, to Ålesund in Norway. According to the Convention for the Protection of the Marine Environment of the North-East Atlantic of 1962 it runs further to the west and north from longitude 5° West and latitude 62° North, at the latitude of Geirangerfjord in Norway.

Currents & Tides

North Sea water flow

The tides are caused by the tide wave from the North Atlantic, as the North Sea itself is too small and too flat to have its own tides. Ebb and flow alternate in a cycle of 12.5 hours. The tide wave, owing to the Coriolis effect, flows around Scotland and then counter-clockwise along the English coast, reaching the German Bight some 12 hours after arriving in Scotland. In so doing, it runs around three amphidromic points: a central point lies shortly before the Straits of Dover. It is formed by the tide wave which is transported through the English Channel. It influences the tides in the narrow area in the Southern Bight between southern [England]] and the Netherlands. The other amphidromic system consists of two points close to each other, which form a tide wave. The two other points just off the coast of southern Norway and lying on a line between southern Denmark and the West Frisian Islands form one single area around which the tides flow. Its central point lies off the coast of Denmark at 55° 25' N, 5° 15' E.

As a result, the tidal range in southern Norway is less than half a metre (1.5 ft), but increases the further any given coast lies from the amphidromic point. Shallow coasts and the funnel effect of narrow straits increase the tidal range. The tidal range is at its greatest at The Wash on the English coast, where it reaches 6.80 m (22 ft). In shallow water areas, the real tidal range is strongly influenced by other factors, such as the position of the coast and the wind at any given moment or the action of storms. In river estuaries, high water levels can considerably amplify the effect of high tide.
