APPENDIX B: WAVE DATA 



Wave data summaries for 1983 and climatological summaries for 198O 



through 1983 are presented in this appendix. An explanation of the summary 



formats is followed by a list of tables and figures, then the data for gages 



615, 620, and 625. Wave data are summarized in the following forms: 



a. Gage histories. Table B1 includes information about the gages, 

 gage installations, and major interruptions in the data collec- 

 tion. Short interruptions in the operational status of the gage 

 are not mentioned. 



b. Time-histories. A continuous display of individual wave height 

 and peak-spectral wave period values are plotted as a function 

 of the time throughout the year (Figures HI, 020, B33). So that 

 the sequence of the data can be followed easily, solid lines 

 connect consecutive data points for times when there is a gap 

 smaller than 24 hr between observations. 



c. Annual; seasonal; and monthly maxima, mean, and standard de- 

 viations of wave height and peak period. The 1983 mean wave 

 height and standard deviation, the mean peak wave period and 

 standard deviation, and the extreme wave heights are listed in 

 Tables B2, HI 2, and B22; I98O through 1983 values are in Ta- 

 bles B7, B17, and B27. Also included is the total number of 

 observations obtained; at four observations per day, the maxi- 

 mum number of observations per month (based on a 30-day period) 

 is 120. 



d. Maxima, mean, and standard deviations of wave height and peak 

 period. The 1983 data presented in the tables described above 

 are also graphed (Figures B2, B21, and B34) for each month and 

 the year; I98O through 1983 are in Figures B11, B27, and B40. 

 The standard deviations are presented as vertical bars origi- 

 nating at the mean value and extending to the mean plus one 

 standard deviation value. The extreme values are plotted 

 above. No extreme period values are presented. 



e. Joint distribution functions of wave height versus peak 

 period. Annual, seasonal, and monthly Joint distribution tables 

 are presented for 1983 in Tables B3-B5, B13-B15, and B23-B25; 

 data for I98O through 1983 are in Tables B8-B10, B18-B20, and 

 B28-B30. Each table gives the frequency (in parts per 1,000) 

 for which the wave height and peak period were within the 

 specified intervals; these values can be converted to percent by 

 dividing by 10. Marginal totals are also included. The raw 

 total gives the total number of observations out of 1,000 which 

 fell within each specified peak period interval. The column 

 total gives the number of observations out of 1,000 which fell 

 within each specified wave height interval. 



f. Cumulative distributions of wave height. For each gage, an- 

 nual, seasonal, and monthly wave height distributions of 1983 

 are plotted in cumulative form in Figures B3-B5, B22-B24, and
