Norwegian Current

The Norwegian electricity is an ocean current that flows from the North Sea in the Norwegian Sea and in the Barents Sea. The flow is the last part of the triggered by the Gulf Stream and continuing through the North Atlantic Current water movement. The Norwegian current brings relatively warm, salty water in Arctic regions.

The stream begins in the Skagerrak and fed by waters of the Baltic and North Sea water that is brought over the Jutland current in the Skagerrak. While, for the most part flows through the Norwegian Trench and the Norwegian coastal shelf, at the Norwegian coast to the north, flowing water from the Norwegian rivers, and warm, salty North Sea water that is added from the North Atlantic Current, into it. The current is bounded on the west by an opposite flow North Atlantic water into the North Sea into it. This creates vortices, which are far greater than in most coastal currents.

The current usually flows in 50 to 100 meters depth. He has a highly variable flow rate, which can be up to 1 meter / second, depending on the measurement range of 5 cm / sec, oceanographers estimate an overall rate of flow of 0.3 to 0.5 meters / second. Compared to the surrounding North Sea but it is cold and low salt, low in comparison to the Arctic waters warm and rich in salt. In winter, the stream has a temperature of 2 ° to 5 ° C, the salinity of less than 34.8 ‰. The separated by a front Atlantic waters of the North Sea, however, is about 6 ° C warm, the salt content is more than 35 ‰.

In years in which winter is a strong current to the north flows, the current ensures greatly reduce the formation of ice in the Barents Sea.

Countercurrent

The warm surface current has a cooler countercurrent in the depths of the Atlantic. This overall system of a kind "heat pump " for the northern European regions and is regarded by some scientists as fragile ocean; it depends on the climatic conditions of the Gulf Stream and of the salt entries and thus by the different densities of water. A modification of this system would, if it collapses, getting familiar with the Norwegian electricity noticeable. Oceanographers try to map the entire system on computers simulative, but the results so far are contradictory. It is clear that only when the " pump system " actually collapses, then it would be significantly cooler in the whole of Europe.
