A great, circular motion of water in each of the major ocean basins centered on subtropical high-pressure region, with circulation clockwise in the northern hemisphere and counterclockwise in the southern hemisphere.
a major circular moving body of water; it is created as boundary currents get deflected by winds and the Coriolis Effect. There are five gyres in our world ocean. Two each in the Pacific and the Atlantic Oceans and one in the Indian Ocean. They flow clockwise in the northern hemisphere and counter-clockwise in the southern hemisphere
A gyre is any manner of swirling vortex. It is often used to describe wind or ocean currents, for example the North Pacific Gyre. In bodies of water, organisms use gyres for movement from areas of depleted nutrients to areas of higher nutrients.Lecture by Kristine Brenneman, in the Fisheries Biology department at Humboldt State University in Arcata, California Gyres are caused by Coriolis effect.
