In comparing the two sections, the change in the vertical 

 distribution of temperatures during the period between the two sec- 

 tions is evident,, Of particular interest are the changes in slope of 

 the transition layer in the Counter cur rent and the meridional shift in 

 the center of the upwelling c In figure 5„ plots of the 60 , 70 , and 

 80° F. isotherms for each leg of the cruise, are given to show these 

 changes. 



The wind data from both the southbound and northbound 

 legs are summarized in figure 6„ The values from which the arrows 

 were plotted are listed in Table I at the end of the reporto 



Wind speed and direction were recorded at each bathy- 

 thermograph lowering,, These data were averaged for the total lower- 

 ings between each degree of latitude; the speed and direction were 

 averaged separately,, When there was a significant change in either 

 speed or direction within 1 degree of latitude, i^c, 8 - 9 N. , south- 

 bound section, less than the normal spacing of 1° of latitude was used. 



Resultant winds were not calculated, as the observational 

 accuracy does not warrant this treatment and as the change in either 

 speed or direction within the 60-mile limits was usually within the 

 accuracy of measurement,. The data for each observation (number of 

 observations shown at base of arrows) are available at the POFI, the 

 Scripps Institution of Oceanography, and the U„ S. Navy Hydrographic 

 Office „ 



During the southbound leg the winds were predominantly 

 from the NE to about 8° N. , at which time they became light and 

 variable and continued so to about 4° N„ From 4 N„ to the southern 

 limit of the section the general direction shifted from southeasterly 

 to easterly c Along the northbound leg the arrows show predominantly 

 NE to E„ winds 



Sigma-t, salinity, inorganic phosphate, and oxygen; 

 Montgomery (1954) points out the desirability of presenting the several 

 variables, i e„, temperature, salinity, phosphate, etc„ , in such a 

 manner that the consistency among the several fields is readily vis- 

 ible,, This can most easily be achieved by selecting a reference 

 variable, and in this report sigma-t was the choice 



The data for sigma-t at an isopleth interval of o 2 g/1, 

 as read from plots relating temperature, salinity, and sigma-t 

 (Cromwell 1954, fig„ 1), were plotted for each station along with 

 the observed values,, The isopleths were then drawn (fig„ 7)„ There 

 was some smoothing, but with no violation of the observed points,,
