 Cross-hatching shows water that is practically isothermal vertically. 



and 2-12 (S-p). Note that where alternative 

 choices are available (e.g., salinity value at 

 BT 3 same as that at BT 7) 1 chose the value 



£ to maximize the gradient. 



t The two hydrocasts at front 2 (one on either 



- side) were relatively far from the front, and 

 ; any profiles derived from their data would not 

 I be highly meaningful. There was evidently a 

 ' strong thermocline at about 60 m. Isotherms 

 ; cutting the surface in the middle or on the cool 

 S side were deeper on the warm side. The salinity 

 \ data from the hydrocasts suggest a connpli- 



- cated salinity structure, like that of front 5. 

 The nature of this complication is partially 

 shown by the T-S curves for the two hydro - 

 casts (fig. 35). According to the T-S curve 

 for the warm side, the water is fairly typical 

 California Current water below about 50 m.
