- "A Cooperative Effort Towards
Understanding of the
Oceanography of the Eastern Tropical Pacific Ocean" -
an international cooperative investigation of the eastern tropical
Pacific Ocean. The stated goals were to provide data necessary for a
more efficient 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 of the region. The U.S.
Commercial Fisheries (now National Marine Fisheries Service) was the
coordinating agency. Participating scientists were primarily from the
National Marine Fisheries Service, Scripps Institution of Oceanography,
and the Inter-American Tropical Tuna Commission.
The field work, from February 1967 through March 1968, was divided into seven 2-month cruise periods (Figure 1). There were three general classes of ships taking part in the field operations: the principal participating ships, all operated by U.S. organizations; Latin American cooperating ships; and ships of opportunity (Table 1).
At a meeting of the EASTROPAC coordinating committee held in April 1968, it was decided that the data collected on the cruises were so numerous that classical data reports would be impractical and that a comprehensive atlas of the physical and biological results of the project should be produced instead. The atlas was divided into 11 volumes, with five volumes containing physical oceanographic and meteorological data from the principal participating ships, and five volumes containing biological and nutrient chemistry data from the same ships. Volume 11 contains all data from the Latin American cooperating ships and ships of opportunity.
