SUMMARY AND CONCLUSIONS 



The sections of temperature structure between a point off 

 San Diego to Honolulu provided new detailed data of the upper 

 layers of the sea. 



The slope of the isotherms in two levels at 16 locations re- 

 vealed that the median absolute value generally became less steep 

 away from the California coast. Similarly, the deeper of the two 

 isotherms, selected where the vertical temperature gradient was 

 weak, had a greater number of larger vertical angles than the 

 shallow one. 



The autocorrelation of successive depth values of given iso- 

 therms became smaller more rapidly with increased distance from 

 the California coast. The power spectrum of the depth of iso- 

 therms showed peaks at varying frequencies. The higher and more 

 significant peaks appear to be most numerous in a zone half way to 

 Hawaii than in other parts of the section.
