Generally, an estuary has a wide range of 

 environmental conditions, but the extent or 

 size of a particular zone may be a factor con- 

 trolling a species' success or failure. 



Most of the data collected during 1963 and 

 1964 have been entered on about 250,000 cards 

 for automatic data processing (ADP). Our 

 acquisition of a key punch and sorter has 

 speeded this work considerably {fig. 25). 



During fiscal year 1965 we installed radio 

 equipment, which enables us to communi- 



cate directly with our vessels in the field 

 (fig. 26). 



We continue to enjoy excellent cooperation 

 in the exchange of data and services with 

 many Federal, state, and private organiza- 

 tions. Most recently, we provided assistance 

 to the National Aeronautics and Space Admin- 

 istration by analyzing sediment samples from 

 several of their test areas.

 1963 and 1964 have been transcribed to more than 250,000 cards to facilitate their storage, 

 retrieval, tabulation, and analysis.
