PROBLEM 



Develop the theory of internal waves in the ocean. Design and perform 

 experiments to obtain needed military information. Specifically, investigate the 

 diffusion of a solute through discrete layers of solvent, and develop a technique 

 for measuring diffusion without disturbing the diffusion process. 



RESULT 



A technique was developed for determining the rate of diffusion between 

 two discrete layers by taking minute samples at regular intervals with a microcell 

 and determining concentration by conductivity measurement. 



RECOMMENDATION 



Apply the technique to investigation of the effect of wave action on dif- 

 fusion between discrete layers. 



ADMINISTRATIVE INFORMATION 



Work was performed under SR 104 03 01, Task 0594 (NEL L41171) between 

 January and September 1962. The report was approved for publication 26 July 1966.
