Normal Thermocline 



Normal thermoclines reflect an average condition, and their 

 wavelength, although irregular, varies from 1400 to 2400 feet. 

 Examples from the areas marked N-l and N-2 (fig. 10) are pre- 

 sented (figs. 12A and 12B), and are derived from the general area 

 where smooth examples S-l and S-2 were found.
