Data Analysis in Washington, D.C. These facilities are working with 

 individual investigators to ensure that all data are recorded and 

 available in appropriate forms. 



IFYGL data analysis began during the year in eight major areas of 

 study — terrestrial water budget, lake heat balance, water move- 

 ment, atmospheric water balance, atmospheric boundary layer, 

 evaporation synthesis, lake chemistry and biology, and simulation. 

 Altogether there are 75 American and 81 Canadian tasks. Several 

 models to describe and predict processes occurring in Lake Ontario 

 are under development or test and evaluation. The ultimate aim of 

 IFYGL is to develop an information base and models that will be 

 useful in assessing the environmental impact of various alternatives 

 for developing the resources and controlling pollution of the Great 

 Lakes. 



The Marine Resources Monitoring, Assessment, and Prediction 

 program (MARMAP) is a nationally coordinated program of 

 NOAA's National Marine Fisheries Service to monitor, assess, and 

 predict the kinds and quantities of living marine resources available 

 to the people of the United States, and to provide a comprehensive 

 data base for domestic and international management of these re- 



The 1972 MARMAP cruises to assess the distribution of fish eggs and larvae 

 found widespread contamination of surface waters by oil residues. Over half of 

 the plankton samples collected in surface layers contained clumps of tar.
