and jellyfish) were accompanied by a widespread failure of 

 anchovy reproduction. The closure of the anchovy fishery had 

 an international economic ripple effect and imposed consider- 

 able hardship on the economy of Peru. The distinctly different 

 conditions present in MAM 77 and the absence of any of the 

 strong anomaly indicators (anoxia, dinoflagellates, and jellyfish) 

 provide a basis for predicting that the reproductive failure will 

 not be repeated this year. The oceanographic observations of 

 JOINT-II for MAM 77 have been used by the Government of 

 Peru to evolve their strategy for fishery management during this 

 critical period. Thus, social application and scientific analysis of 

 JOINT-II are proceeding simultaneously. 



With completion of the JOINT-II field work in mid- 1977, 

 CUEA began data processing, analysis, interpretation, and syn- 

 thesis (called SYNAPSE — Synthesis and Publication Segment), 

 which will be the full project effort for at least the next 2 years. 

 The plan for SYNAPSE involves individual component data 

 processing and analysis, small group interactions, program-wide 



meetings and workshops for data synthesis, national and inter- 

 national forums for presentation to the scientific community, 

 and publication of data and synthesized results.
