 frequency bands can be best obtained by inspecting the full spectrum, examples 

 of which are included in Appendix B for gage 625 during storm wave conditions. 



Water Level Data 



Collection 



46. The water level information was obtained from a NOS tide gage which 

 produced a digital paper tape of instantaneous water levels sampled continu- 

 ously at 6-min intervals. At the end of each month, the paper tape was re- 

 moved from the recorder and mailed to NOS in Rockville, Md., for analysis. 

 Analysis 



47. The digital paper tape records of tide heights taken every 6 min 

 were analyzed by the Tides Analysis Branch of NOS. An interpreter created a 

 digital magnetic computer tape from the punch paper tape, which was then pro- 

 cessed on a large computer. First, a listing of the instantaneous tidal 

 height values was created for visual inspection. If errors were encountered, 

 a computer program was used to fill in or recreate bad or missing data by 

 using correct values from the nearest NOS tide station and accounting for
