below the main thermocline . Both A and B contain considerable 

 variation in the autocorrelation values with reference to longitude. 

 However, there is some similarity in the fluctuation. As might be 

 expected, the value of /?^ is nearly always less for the greater 

 lags (120) than for the fewer lags (60). The values of autocorrela- 

 tion (fig. 7), like those of the slopes (fig. 5), decrease slightly 

 from the San Diego area toward Honolulu,
