OBSERVED DISTRIBUTION OF TEMPERATURE AND SALINITY 157 



As the water masses under consideration exhibit a general northward trend, it will be more con- 

 venient to treat the results of both surveys from south to north, and not, therefore, in the chrono- 

 logical order of the stations worked during survey I. 



The charts showing the distribution of surface-temperature (Fig. 7) and surface-salinity (Fig. 8) 

 show that on both surveys the isotherms and isohalines ran more or less parallel to the coast. Within

this system the cooler and less saline waters lay adjacent to the land, and the warmer, more saline 

 waters farther offshore. Superimposed upon this distribution, however, there was a pronounced series 

 of tongue-like formations within which the cooler coastal waters alternated with intrusions of the 

 warmer oceanic waters lying to the west. Thus the cool waters were not in the form of a continuous 

 belt along the coast, but rather were present as a series of isolated patches extending out from the 

 coast and entering into eddies with the warmer oceanic waters. It will be shown, further, that within 

 these eddies the cooler coastal waters were sharply separated from the warm oceanic surface-waters.
