ABSTRACT 



This atlas contains charts depicting the distribution of 

 physical, chemical, and biological oceanographic prop- 

 erties and associated meteorological properties ob- 

 served during EASTROPAC. EASTROPAC was an interna- 

 tional cooperative investigation of the eastern tropical 

 Pacific Ocean (20° N. to 20 S., and from the west coasts of 

 the American continents to 119° W.) which was intended 

 to provide data necessary for a more effective use of the 

 marine resources of the area, especially tropical tunas, 

 and also to increase knowledge of the ocean circulation, 

 air-sea interaction, and ecology. The Bureau of Commer- 

 cial Fisheries (now National Marine Fisheries Service) 

 was the coordinating agency. The field work, from Feb- 

 ruary 1967 through March 1968, was divided into seven 

 2-month cruise periods. During each cruise period one or 

 more ships were operating in the study area. 



On completion of the field work the data seemed too 

 numerous for a classical data report. Instead, it was de- 

 cided to produce an 1 1-volume atlas of the results, with 5 

 volumes containing physical oceanographic and 

 meteorological data from the principal participating 

 ships, 5 volumes containing biological and nutrient 

 chemistry data from the same ships, and 1 volume con- 

 taining all data from Latin American cooperating ships 

 and ships of opportunity. Extensive use was made of a 

 computer and automatic plotter in preparation of the 

 atlas charts. Methods used to collect and process the data 

 upon which the atlas is based are described in detail by 

 the contributors of the following categories of charts: 

 temperature, salinity, and derived quantities; thicknessof 

 the upper mixed layer; dissolved oxygen; meteorology; 

 nutrient chemistry; phytoplankton standing stocks and 

 production; zooplankton and fish larvae; micronekton; 

 birds, fish schools, and marine mammals.
