Appendix E 
Wave Data for Gauge 641 
Wave data summaries for Gauge 641 for 1994 and for 1980 through 
1994! are presented in the following pages. 
Daily Ho and Tp 
Figure E1 displays the individual wave height H,,, and peak spectral 
wave period T, values, along with the monthly mean values. 
Joint Distributions of Hino and Tp 
Annual and monthly joint distribution tables are presented in Tables E1 
and E2, and data for 1980 through 1994 are in Tables E3 and E4. Each table 
gives the frequency (in parts per 10,000) for which the wave height and peak 
period were within the specified intervals; these values can be converted to 
percentages by dividing by 100. Marginal totals are also included. The row 
total gives the number of observations out of 10,000 that fell within each 
specified peak period interval. The column total gives the number of observa- 
tions out of 10,000 that fell within each specified wave height interval. 
Cumulative Distributions of Wave Height 
Annual and monthly wave height distributions for 1994 are plotted in 
cumulative form in Figures E2 and E3. Data for 1980 through 1994 are 
plotted in Figure E4. 
1 Data from 1980 through May 1992 are from staff Gauge 645 which was replaced by 
pressure Gauge 641 in November 1992.
