there appears to be a cycle of even longer duration 

 superimposed on the annual variation. 



The vertical temperature distribution for the 

 patrols is shown in figures 4-32. A near isother- 

 mal condition existed to 1.500 meters during the 

 February-March 1968 patrol of the CGC HAMIL- 

 TON (fig. 6). The surface temperatures decreased 

 due to seasonal cooling and finally reached a 

 minimum of 2.87°C in April 1968. Seasonal 

 warming of the surface water then occurred until a 

 maximum surface temperature of 9.03°C was at- 



tained in September 1968. The surface tempera- 

 tures then decreased until April 1969 when the 

 seasonal minimum surface temperature was again 

 reached; the surface temperature at this time was 

 2.21°C, the coldest surface temperature recorded 

 from a oceanographic cast at OS BRAVO since 

 this program started in 1964. 



The vertical salinity distribution for the patrols 

 is shown in figures 33-61. Surface salinities in- 

 creased from November 1967 (fig. 33) to Feb- 

 ruary 1968 (fig. 35), when the surface salinity
