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
Atlantic Europe continues today. There is a multi-national association of regions, which acts as a co-ordinator of Atlantic European regions and its interests. This is the "Atlantic Arc Commission". Operative since 1989, it includes 26 regions from four member States - Great Britain, France, Spain and Portugal. The Atlantic Arc Commission is one of the seven "Geographical Commissions in the Conference of Peripheral Maritime Regions of Europe". Atlantic Europe Atlantic Europe is a geographical and anthropological term for the western portion of Europe which borders the Atlantic Ocean.
