APPENDIX B: WAVE DATA 



Wave data are summarized in the following forms: 



a. Gage histories. Tables Bl, BIO, B19, and B28 include informa- 

 tion about the gage, its installation, and major interruptions 

 in the data collection. Short interruptions in the operational 

 status of the gage are not mentioned. 



b. Time histories. All wave height H and peak spectral wave 

 - m 



period T values are plotted as functions of the time through- 

 out the year (Figures Bl , B2, B14, B15, B22, B23, B30, and B31) . 

 So that the sequence of the data can be followed easily, solid 

 lines connect consecutive data points for times when there is a 

 gap of fewer than 24 hr between observations. 



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

 ations of wave height and peak period. Mean H and standard 



deviation, mean T and standard deviation, and the extreme 



P 

 H for 1981 and for 1980 plus 1981 are listed in Tables B2, 

 m 



B3° Bll, B12, B20, B21, B29 , and B30. Also included is the to- 

 tal number of observations obtained. At four observations per 

 day, the maximum number of observations per month (based on a 

 30-day period) is 120. 



d. Extreme, mean, and standard deviations of wave height and mean 

 and standard deviations of peak period. The data presented in 

 the tables described above are also graphed (Figures B3, B4, 

 B16, B17, B24, B25 , B32, and B33) for each month and for the 

 year for 1981 and for 1980 plus 1981. Standard deviations are 

 presented as vertical bars originating 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. 

 Joint distribution tables for 1981 and for 1980 plus 1981 are 

 tabulated for each year and season (Tables B4, B6, B13, B15, 

 B22, B24, B31, and B33) and for each month (Tables B5, B7 , Bl4, 

 B16, B23, B25, B32, and B34) . Each table gives the frequency 

 (in parts per 1,000) for which H and T were within the 



specified intervals; these values can be converted to percent 

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

 labeled "Total" gives the total number of observations out of 

 1,000 which fell within each specified period interval. The 

 column "Total" gives the number of observations out of 1,000 

 which fell within each specified height interval. 



f. Cumulative distributions of wave height. For each gage, H^ 



distributions are plotted in cumulative form (Figures B5 , B6, 

 B18, B19, B26, B27, B34, and B35 .
