It has been demonstrated at the Mission Beach Site, and on the 

 basis of wind alone, that it is possible to forecast the daily average 

 thermocline depth with a standard deviation of ± 5 feet, and to forecast 

 the average hourly depth with a standard deviation of ± 13 feet. 



It has been established that, although the overall motion of the 

 thermocline is in response to the wind, internal tidal oscillations are 

 superimposed on this motion. These are shown to be frequency-coupled 

 to the surface tide and are, on the average, about five times as great 

 in amplitude. 



The results of this program are in excellent agreement with the 

 Ekman transport theory. It is therefore believed that the linear form 

 of equation (l), with appropriate parameters, will be applicable to any 

 extended coastline.
