APPENDIX H 



INCIDENT AND TRANSMITTED WAVE SPECTRAL PLOTS 



Appendix H contains the incident and transmitted wave spectral 

 plots along with the corresponding transmission response curve for 11 

 representative records. The data for the first nine were recorded at 

 Friday Harbor, Washington, during the winter of 1975. Figures H-11 and 

 H-12 were computed from similar data collected in Alaska during the 

 winters of 1974 and 1975. 



The original time series were high-pass filtered at a cutoff fre- 

 quency of 0.05 hertz to remove tidal drift. Each series consisted of 

 2,048 data samples and were sampled at a period of 0.5 second for the 

 Friday Harbor data and 0.44 second for the Alaska data. 



The standard deviations and corresponding overall transmission 

 coefficients for each of the Friday Harbor plots are given in Appendix 

 G.
