 in the Pacific. Tellus 5:308-14. 



Noted changes in intensity and north-south 



location of divergence and convergence zones 



o 

 at boundaries of the countercur rent (lat. 5 N 



and 10 N) . 



KEY WORDS: oceanography, currents, season, 

 distribution, convergence/d ivergence . 



Jerlov, N.G. 1956. The equatorial currents in the 

 Pacific Ocean. Rep. Swed . Deep-Sea Exped. 3(6): 

 129-154. 



Presented plan view and vertical sections of 

 oceanographic data from four crossings of the 

 equator in 1947. Pointed out major features 

 and seasonal variations. Concluded that "the 

 mechanism of the equatorial currents may 

 principally be understood from the action of 

 prevailing winds." 



KEY WORDS: oceanography, temperature, salin- 

 ity, density, depth, season, currents, dis- 

 continuity, divergence, winds.

Abstract only. In years with above normal 

 sea surface temperatures, albacore landings 

 in general were greater than in years of 

 below normal temperatures. Whereas warm 

 waters did not ensure a good fishery, wide- 

 spread cold waters were detrimental to fish- 

 ing success. 



KEY WORDS: tuna, albacore, temperatures, 

 catch .
