goals of the program have been reached and 

 in many respects exceeded. The concept and 

 operation of a system for continuously meas- 

 uring salinity, temperature, oxygen and 

 nephelometry profiles have been proved. The 

 precision obtained for these and other chemi- 

 cal determinations was better than those 

 v^fhich had been taken as goals — in general, 

 goals which until then were beyond the state 

 of the art. The computing system used in the 

 Atlantic legs enabled preliminary cruise re- 

 ports to be produced in a few weeks. 



Four large-volume stations in the North 



Atlantic (numbers 3, 11, 17, 19] have been 

 designated key stations. Analyses of these 

 stations were done on a priority basis by the 

 cooperating laboratories so that results would 

 be available for discussion at the Summer In- 

 stitute held May 7-11, 1973, at Woods Hole. 



Although it is too early to have sufficient 

 scientific results at hand for evaluation, it is 

 clear that GEOSECS data on the complex in- 

 terfingering of water masses will produce a 

 far more detailed picture than has yet been 

 achieved and that our understanding of water 

 movement will undergo a major advance.
