IV. CURRENT VELOCITIES 



The presence of surface currents exceeding one knot was noted 

 throughout the area by the three ships. Currents of this magnitude 

 are not recorded on any charts of the area. The calculated velocities 

 shown in figures 10 and 11 are further evidence of the existence of 

 amounts in excess of 1 knot* Figure 10 represents the velocity 

 -through cross sections computed from volume transport. Figure 11 

 depicts surface speeds as determined by dynamic topography relative 

 to U00 meters. It is considered of slight importance that the 

 determined velocities do not agree quantitatively with the GEK's, 

 since the computed currents are averages across sections often 

 exceeding 60 miles in length. The significant feature Is that the 

 magnitudes of the calculated currents and of the GEK's agree well 

 in most cases.
