A harmonic analysis of short and long-term 

 variations in sea surface temperatures and 

 sea surface salinities at the two stations. 



KEY WORDS: oceanography, temperature, sali- 

 nity, tuna, skipjack, distribution, migra- 

 tion . 



Sette, O.E. 1955. Consideration of midocean fish pro- 

 duction as related to oceanic circulatory systems. 

 J. Mar. Res. 14 (4 ): 398-414 . 



A general discussion of mid-Pacific Ocean dy- 

 namics and bioprod uct ivi ty climaxing with 

 tunas. Divergence and convergence features 

 provided the basic support for a persistant 

 concentrated stock of yellowfin.

upwelling, convergence, currents, depth, 

 enr ichment .

stocks of tuna by the equatorial circulation 

 system. Proc. Pac. Sci. Congr. 8 (3 ): 131-148 . 



An outline of hydrographic and exploratory 

 fishing observations and preliminary results 

 of Pacific Oceanic Fishery Investigations up 

 to 1953. He described the effect of wind on 

 ocean circulation in the tropcial band and 

 presented a nonmathematical model of physi- 

 cal-dynamic processes leading to apex pred- 

 ators (tuna) production.

 wind, convergence/divergence, upwelling, 

 nutrients, currents, food.
