Stevenson, M.R. 1970. On the physical and biological 

 oceanography near the entrance of the Gulf of 

 California, October 1966 - August 1967. [In Engl, 

 and Span.] Inter-Am. Trop. Tuna Comm. Bull. 

 14: 389-504. 



Descriptive oceanography of the specified 

 area based on data from "Mazatlan Project" 

 (part of the EASTROPAC expedition series). 



KEY WORDS: oceanography, temperature, sali- 

 nity, depth, upwelling, currents, season.

 ments by aerial radiometry and tuna concentrations 

 in the Gulf of Guinea. In G.H. Tomczak (editor), 

 Environmental analyses in marine fisheries re- 

 search--Fisher ies Environmental Services, p. 62- 

 65. FAO Fish. Tech. Pap. 170. 



Described the operation for developing sea 

 surface temperature and front maps from re- 

 search vessels and aircraft for use in advi- 

 sories to the tuna fleet. Used a mix of 

 real-time data plus historical data and a 

 model input for subsurface structure inter- 

 pretations . 



KEY WORDS: tuna, yellowfin, skipjack, ocean- 

 ography, temperature, thermocline, depth, 

 fronts, feed, enrichment.

 positions classified by ocean current. [In Jpn . , 

 Engl. abstr.] Bull. Jpn. Soc. Sci. Fish. 

 21 (12) : 1194-1198. 



21 (12) : 1194-1198. 



Compared albacore size composition among 

 several current areas and concluded that the 

 evidence indicated that the various ocean 

 currents presented an environment consider- 

 ably different from each other for the tunas. 



KEY WORDS: tuna, albacore, size, distribu- 

 tion, geography, oceanography, currents.
