Major Oceanic Gyres and Sea Currents

Major Oceanic Gyres and Sea Currents

The global oceanic system has five major sea current gyres that act as large conveyor belts. These gyres are also correlated with dominant wind flows where they rotate clockwise north of the equator and counterclockwise south of the equator. During the era of sail ship navigation, these gyres had a strong impact on navigation and trade flows.
