to the number of the particular gage. Both of these file types had one tidal 

 elevation word as well as the corresponding time word in each data record. 

 The date- time interval of the "specified" files was from 4 August 1987 at 

 approximately 0700 hr to 7 September 1987 at approximately 0000 hr. The full- 

 length data set intervals varied, depending on individual gage deployment and 

 recovery times. Both were unformatted, sequential access files of record 

 length 2. The first 56 records are character strings concatenated into seven 

 64-character information strings. A typical open statement for a tide eleva- 

 tion file is as follows: 



OPEN (UNIT=1,FILE='TGIW. DAT' , F0RM= ' UNFORMATTED ' ,STATS='0LD' , REC0RDLENGTH=2 ) 



63. Plots of tidal elevation for the full data set, the "specified" 

 data set, and a representative 2-day interval (7 and 8 August) and a 4-hr in- 

 terval (0000 to 0400 hr, 8 August) are shown for tide Gages 1, 2, 3, 6, and 7 

 in Appendix D. 



64. Similar analysis was carried out on the eight data sets from the 

 wave gages. A "specified" data set was not plotted since the specified inter- 

 val overlapped the two data sets. The whole time series, a 2 -day plot on 



7 and 8 August for the "A" data sets, a 2-day plot on 16 and 17 August for the 

 "B" data sets, and the same 4-hr interval are also plotted in Appendix D.
