Ocean current hemisphere due to imposed wind stresses. In these wind-driven currents, the Ekman spiral effect results in the currents flowing at an angle to the driving winds. In addition, the areas of surface ocean currents move somewhat with the seasons; this is most notable in equatorial currents. Deep ocean basins generally have a non-symmetric surface current, in that the eastern equatorward-flowing branch is broad and diffuse whereas the western poleward flowing branch is very narrow. These western boundary currents (of which the Gulf Stream is an example) are a consequence of the rotation of the Earth. Deep ocean currents are driven
Norwegian Current Norwegian Current The Norwegian Current (also known as the Norwegian Coastal Current) is a water current that flows northeasterly along the Atlantic coast of Norway at depths of between 50 and 100 metres through the Barents Sea Opening into the Barents Sea. It contrasts with the North Atlantic Current because it is colder and contains less salt, having most of its tributary water coming from the slightly brackish North and Baltic seas, as well as the Norwegian fjords and rivers. It is, however, considerably warmer and saltier than the Arctic Ocean, which is freshened by the ice in and around
