The descriptions of eight principal currents in this report are based on 

 data obtained hy direct methods in regions from the Bering Sea to Cape 

 Horn. Except for the Peru and Cape Horn Currents, surface flows appear 

 to be ill defined and exhibit characteristic variability. The usual graphic 

 presentation of ocean currents is, at best, a static picture. The surface of 

 the ocean is in constant motion, the movement being exceedingly variable 

 in some regions and relatively constant in others. The currents described 

 in this report are those where the movement within specified boundaries 

 exhibits a permanent or seasonal flow.
