13 ABSTRACT 



The sea temperature structure of the upper layers was investigated by 

 the use of a thermistor chain towed off the southern extremity of Baja 

 California, Mexico, which revealed vertical and horizontal motion, 

 large scale turbulence, and possible Doppler effects. The thermoclines 

 were categorized in four types, smooth, normal, rough, and irregular. 

 The power spectrum of vertical oscillation in the thermocline showed 

 small peaks at wavelengths of 0. 3 and 0. 7 mile. The slopes of 

 isotherms were determined from a study of over 6 5, 000 data samplings.
