NettetThis is a map ocean surface currents from 1877. (John James Wild, 1877) At the surface, currents are mainly driven by four factors—wind, the Sun’s radiation, gravity, and Earth’s rotation. All of these factors are interconnected. The Sun’s radiation creates prevailing wind patterns, which push ocean water to bunch in hills and valleys. NettetWhen currents above the surface are deflected by 45 degrees, the Ekman spiral forms, while currents below the surface are deflected less as depth increases. The spiral design can drop to around 330 feet below the surface. Do All Oceans Have Gyres? Yes, all of the oceans on earth have at least one gyre.
