tors, must have modified the normal food chain dynamics. In 

 the 15° S region, where the intensive effort of JOINT-II was 

 located, a layer of anoxic, denitrified, and hydrogen sulfide- 

 bearing water developed in the undercurrent (fig. 45). The asso- 

 ciation of the dinoflagellate bloom, jellyfish, and anoxia, none 

 of which was present in MAM 77, lead the CUEA scientists 

 to look for fundamental differences in the atmospheric and 

 oceanographic forcing processes for the two periods, MAM 76 

 vs. MAM 77. Indeed, the requisite differences appear to be 

 present in some large-scale properties, but not necessarily in the 

 local wind fields. 



MAM 77, distinctly different from MAM 76, is also quite 

 distinct from the conditions prevailing at the JOINT-II site in 

 1966 and 1969. Primary production was lower, and the per- 

 sistent upwelling center just south of Cabo Nazca was more 

 strongly developed in terms of the characteristics of the low 

 temperature, high nitrate, and very low chlorophyll (fig. 46). 

 First analysis suggests that MAM 77 was a period of stronger 

 than average upwelling, especially in relation to the conditions 

 present in 1966 and 1969. 



One aspect of major international consequence is that the 

 highly unusual 1976 conditions (anoxia, dinoflagellate bloom,
