A formation of long wavelength ocean surface waves on the sea. Swells are far more stable in their directions and frequency than normal oceanic waves since they are formed by tropical storms and by stable wind systems. (www.answers.com)

current:
 
current:
  
−
A current, in a river or stream, is the flow of water influenced by gravity as the water moves downhill to reduce its potential energy. The current varies spatially as well as temporally within the stream, dependent upon the flow volume of water, stream gradient, and channel geometrics. In tidal zones, the current in rivers and streams may reverse on the flood tide before resuming on the ebb tide. (www.answers.com)
+
The non-tidal horizontal movement of the sea which may be in the upper, lower or in all layers.  In some areas this movement may be nearly constant in rate and direction while in others it may vary seasonally of fluctuate with changes in meterorological conditions.  The term is often used improperly to denote tidal streams.
