What is the correct term for an area of rotating currents in an ocean

I believe the answer is "When ocean currents combine, they create an area of rotating currents called a(n) gyre."

In oceanography, a gyre is any large system of circulating ocean currents, particularly those involved with large wind movements. Gyres are caused by the Coriolis effect; planetary vorticity along with horizontal and vertical friction, determine the circulation patterns from the wind stress curl.
