CONCLUSIONS 



The study has shown that the resolution of the Fourier amplitude 

 spectra is not high enough to permit accepting them, and the conclusions 

 they suggest, with complete confidence. The chain records do not permit 

 interpretation of vertical changes in the amplitudes by the eigenfunctions. 

 The actual density distribution is available to compute phase velocities of the 

 internal waves in the area under consideration. However, the continous shift 

 in the spectrum supports the theoretical results described in the section on 

 forced internal waves (pp. 16-20 ) . Therefore, the numerical results give a 

 tentative picture which can be checked by additional measurement. 



RECOMMENDATIONS 



1. Verify the theory of internal waves of tidal period with additional 

 measurements with the thermistor chain. 



2. For a complete analysis of the various modes of internal waves, ex- 

 tend measurement of the thermal structure to the sea floor. 



3. Supplement the study of internal waves by the use of current meters 

 and salinometers mounted on the chain or at anchored stations; use the 

 date produced to increase the usefulness of thermistor-chain data in the 

 study of the ocean structure (sound-velocity structure) controlled by non- 

 periodic motion such as advection.
