Oceanic water circulation systems are termed

- Upwellings

-atolls

-ebbs

-gyres

-pulses

- gyres

Explanation:

Gyres -

It is the large system of circulating ocean currents which involve wind movements also.

The reason for the Gyres is the Coriolis effect, i. e., the planetary vorticity along with vertical and horizontal friction, are responsible to determine the ocean current pattern with respect to the movement of the winds.

The five main ocean gyres are as follows -

South Pacific Gyre South Atlantic Gyre North Pacific Gyre North Atlantic Gyre Indian Ocean Gyre

The term gyre can be used to refer to any type of vortex in an atmosphere or a sea, even one that is man-made, but it is most commonly used in oceanography to refer to the major ocean systems.

The following are the five most notable ocean gyres:[2]

Indian Ocean Gyre (generally flowing counter-clockwise)

North Atlantic Gyre

North Pacific Gyre

South Atlantic Gyre
