CONCLUSION 



In the trade wind zone the seasonal and year-to-yeai- changes 

 in temperature and salinity are of the same order of magni- 

 tude. It cannot, therefore, be inferred that a distribution found 

 during any one of the months shown in this circular will be the 

 same as during the same month of other years. The sections 

 are, however, a reference to the characteristic distribution of 

 the temperature, salinity, and water masses in the trade wind 

 zone of the central North Pacific and give an indication of the 

 limits of occurrence and month-to-month variability of these 

 properties. If more detailed information is desired, the read- 

 er is referred to the tabulations of the original data (Charnell, 

 Au, and Seckel, 1967a-f).
