APPENDIX B: WAVE DATA 
Wave data summaries for 1982 and climatological summaries for 1980 through 
1982 are presented in this appendix. The wave data are summarized in the 
following forms:

Gage histories. Table B1 includes information about the gages, gage 
installations, and major interruptions in the data collection at the 
Coastal Engineering Research Center's (CERC's) Field Research Facil- 
ity (FRF) in Duck, N. C. Short interruptions in the operational 
status of the gages are not mentioned. 
Time-histories. A continuous display of individual wave height and 
peak spectral wave period values are plotted as a function of time 
throughout the year (Figures B1, B14, B22, and B30). So that the 
sequence of the data can be followed easily, solid lines connect 
consecutive data points for times when there are fewer than 24 hr 
between observations. 
Annual, seasonal, and monthly maxima, mean, and standard deviations 
of wave height and peak period. Mean 1982 wave height and standard 
deviation, mean peak wave period and standard deviation, and extreme 
wave heights are listed in Tables B2, B10, B18, and B26; 1980 
through 1982 values are in Tables B6, B14, B22, and B30. Also 
included is the total number of observations obtained. At four 
observations per day, the maximum number of observations per month 
(based on a 30-day period) is 120. 
Maxima, mean, and standard deviations of wave height and peak 
period. The 1982 data presented in the tables described above are 
also graphed (Figures B2, B15, B23, and B31) for each month and the 
year; 1980 through 1982 data are graphed in Figures B9, B19, B27, 
and B35. The 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. 
Joint distribution functions of wave height versus peak period. 
Annual, seasonal, and monthly joint distribution tables are 
presented for 1982 in Tables B3, B4, B11, B12, B19, B20, B27, and 
B28. Data for 1980 through 1982 are in Tables B7, B8, B15, B16, 
B23, B24, B31, and B32. 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 row total 
gives the total number of observations out of 1,000 which fell 
within each specified wave height interval. The column total gives 
the number of observations out of 1,000 which fell within each 
specified peak period interval. 
Cumulative distributions of wave height. For each gage, annual, 
seasonal, and monthly wave height distributions for 1982 are plotted 
in cumulative form in Figures B3, B4, B16, B17, B24, B25, B32, and 
B33; data for 1980 through 1982 are in Figures B10, B20, B28, and 
B36.
