been quite regular for each of the years 

 1964-1967, with the maximum surface temper- 

 ature occurring in late August and early Sep- 

 tember, and the minimum generally occurring 

 in April. 



The primary salinity minimum of the sur- 

 face occurs in September with a secondary 

 minimum following three months later in De- 

 cember. The salinity maximum coincides with 

 the temperature minimum in April. 



A comparison of figures 21 and 31 shows 

 that the depth of penetration of the surface 

 temperature is controlled by the halocline. 

 Since the halocline is present throughout the 

 major part of the year, it appears as though 

 there would be little overturn of the water col- 

 umn in the vicinity of Ocean Station BRAVO. 



However, this can not be substantiated until 

 parameters other than temperature and salin- 

 ity are studied on a time series basis in this vi- 

 cinity.
