 bathythermograph observations, the positions of which are shown on Fig. 1. 



Second survey (spring) 



Horizontal distribution of temperature and salinity 

 On survey II the trend of the surface isotherms and isohalines was similar to that on survey I, but 

 throughout the whole region the temperatures were markedly lower. This can to a large extent be 

 attributed to the seasonal change, survey II having taken place about the coolest time of the year; but 

 also, as will be shown in what follows, the more active upwelling before and during this survey has also 

 contributed to the overall effect.
