Undercurrent is a flow of water below the surface: In an ocean, a subsurface current , a water current which flows beneath and usually independently of surface currents. In a river, a subsurface current (see whitewater )
In physical oceanography, undertow is the undercurrent that moves offshore while waves approach the shore. Undertow is a natural and universal feature for almost any large body of water; it is a return flow compensating for the onshore-directed average transport of water by the waves in the zone above the wave troughs.
A subsurface ocean current is an oceanic current that runs beneath surface currents. [1] Examples include the Equatorial Undercurrents of the Pacific, Atlantic, and Indian Oceans, the California Undercurrent, [2] and the Agulhas Undercurrent, [3] the deep thermohaline circulation in the Atlantic, and bottom gravity currents near Antarctica.
Major currents in the California Current System: the California Current (the bulkier, vertical blue line), the coastal jet, the Davidson Current and California Undercurrent, and the Southern California Eddy/Countercurrent.

The Cromwell Current (also called Pacific Equatorial Undercurrent or just Equatorial Undercurrent) is an eastward-flowing subsurface current that extends the length of the equator in the Pacific Ocean.
Ocean dynamics define and describe the motion of water within the oceans. Ocean temperature and motion fields can be separated into three distinct layers: mixed (surface) layer, upper ocean (above the thermocline), and deep ocean.
