Description of skipjack habitat. Skipjack 

 inhabit the upper mixed layer having uniform 

 temperatures and salinities with oxygen being 

 near or at saturation. Greatest concentra- 

 tions were limited to temperature range of 

 18°-21°C. Major water masses and currents 

 influenced the distribution both through 

 drift of larvae and possibly of the adults as 

 well. Described larval distribution and 

 geography and adult distribution. Discussed 

 migration routes.

 changing wind systems: with application to El 

 Nino. Phys. Oceanogr. 6 (5 ): 632-64 5 . 



A mathematical model describes the mechanism 

 of the oceans' response to wind changes. He 

 produced a description of the mechanics lead- 

 ing up to El Nino; and the event also expands 

 poleward from the equator to include the 

 Davidson Current area. 



KEY WORDS: oceanography, equatorial, cur- 

 rents, winds. El Nino.
