The 1-year data base scheduled for IFYGL limits the types of 

 analyses that can be performed. Because the IFYGL data record is 

 short, attention will be focused on short-period fluctuations and the 

 theoretical modeling approach. Additional data collection may be 

 necessary to develop the interrelationships between parameters 

 required for simulation models. The design of future data 

 collections, however, should be based upon the results drawn from 

 IFYGL. 



Major results expected from future IFYGL analyses include the 

 following: 



(1) detailed analysis of large-scale processes relative to Lake 

 Ontario and the basin, including the terrestrial water 

 balance. Lake heat balance, atmospheric water and heat 

 balance, and materials balance of the Lake and selected 

 tributaries; 



(2) analysis of the natural distribution and variability of 

 budget terms, lake currents, temperature, internal waves, 

 surface waves, thermal bar, and lake-scale circulation; 



(3) detailed case studies for periods of special interest relating 

 to the lake-atmosphere system; 



(4) analysis of the natural distribution and variability of 

 chemical concentrations and processes including nutrients; 



(5) analysis of the natural distribution and variability of 

 selected biological properties, such as chlorophyll, 

 zooplankton, biomass, and major plankton species; 



(6) models for analysis, diagnosis, prediction, and simulation 

 of physical, chemical, and biological natural distributions 

 and variability and analysis of alternatives pertinent to 

 water resource management. 



A series of scientific reports is anticipated. The first several of the 

 reports will, on the U.S. side, consist of detailed descriptions of the 

 acquisition systems. The results of scientific analyses will be 

 disseminated later in the same series.
