fishing areas as well as in the Gulf of Tehuan- 

 tepec. The resulting data are included in this 

 report. The areas covered are as follows: 



Pacific coast of southern Baja California, 

 some observations on each cruise and espe- 

 cially on TO-59-2; the work on TO-59-2 

 consisted of occupying part of the station 

 pattern normally occupied by ships of the 

 Scripps Institution and Bureau of Commercial 

 Fisheries in connection with the California 

 Cooperative Oceanic Fisheries Investigations 

 (CalCOFI) (fig. 3A) while the CalCOFI ships 

 occupied the rest of the pattern; for CalCOFI 

 purposes this part of cruise TO-59-2 is known 

 as cruise 5908 and will so appear in their 

 reports; 



Mouth of the Gulf of California and along the 

 coast of southern Mexico between latitudes 21° 

 and 16° N., some observations on each cruise; 



From the Gulf of Tehuantepec to the Costa 

 Rica thermal anticline at latitude 8° N., on 

 TO-59-1 only. 



During TO-58-2 the regular STOR program 

 was suspended for a week so that members of 

 another Scripps Institution project could under- 

 take deep dredging (fig. 1A). This work is not 

 mentioned further in this report. Some effort 

 was devoted on the same cruise to mooring and 

 attending unmanned temperature-wind-record- 

 ing stations in Baja California and Gulf of 

 Tehuantepec waters (positions shown in fig. 1), 

 but for various reasons acceptable results were 

 few and do not bear further mention in this 

 report. 



The Inter-American Tropical Tuna Commis- 

 sion and the Geophysics Institute of the National 

 University of Mexico assisted the Scripps Insti- 

 tution in staffing some of the cruises.
