They discussed nonseasonal variations in sea 

 surface temperature occurring in the oceans. 

 These covered large areas and persisted 3 to 

 6 months on the average. The relation of 

 temperature anomalies to wind and radiation 

 anomalies was examined by cross correlation. 

 Significant values were found in some cases, 

 but were best restricted to certain times of 

 the year and certain areas. 



KEY WORDS: oceanography, temperature, wind, 

 season, geography.

Tuna aggregations are found in shallow ther- 

 mocline, upwelling, current boundary and en- 

 richment areas generated by islands, sea 

 mounts, etc. Atmospheric factors influence 

 oceanic dynamics and enhance the fish habi- 

 tat. Bluefin and albacore are temperate and 

 subtropical species often found associated 

 with frontal zones and have a narrow optimal 

 temperature range. Bigeye and yellowfin are 

 pelagic in the equatorial current systems. 

 Skipjack are warm temperate subtropical and 

 tropical widely ranging species. 



KEY WORDS: tunas, yellowfin, skipjack, big- 

 eye, bluefin, albacore, environment, thermo- 



cline, depth, upwelling, currents, disconti- 

 nuities, enrichment, meteorology.
