because they are less influenced by damping. The intensity in the tidal range 

 is about 35m2 (approximately 380 ft^) /harmonic. -^ 



The eigenfunctions, W„{z) , have been computed using the values of r 



rt p 



given in table 2. They are shown for the upper 500 meters in figures 7A and B. 

 The eigenvalues, f for n = 1 to «=11, and the corresponding phase velocities, 

 c according to the approximate formula given in equation 10, are listed below.
