RECOMMENDATIONS 



As an outgrowth of this study the following investigations are 

 indicated: 



1. Determination of how large an area can be covered by 

 one regression surface. 



2. Determination of optimum sampling procedures and 

 sample sizes. 



3. Extension of regression models to include depth as an 

 independent variable. 



4. Application of regression modeling techniques to describ- 

 ing the distribution of other oceanic parameters , such as salinity.
