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 parts of Scandinavia and the Baltic), resulting in similar landscapes with common endemic plant and animal species. From a strictly physical point of view most of the Atlantic European shoreline can be considered a single biogeographical region. Physical geographers label this biogeographical area as the "European Atlantic Domain", part of the Euro-Siberian botanic region. The Atlantic Bronze Age is a cultural complex of the Bronze Age period of approximately 1300–700 BC, that marked the economic and cultural exchange between the current territories of Portugal, Spain, France, Great Britain and Ireland. Via the Bell Beaker culture, Atlantic and Central Europe were
