APPENDIX A 



WAVE DATA 



This appendix presents summaries of the wave gage data in the following 

 formats: 



(a) Gage histories: The gage histories include information about 

 the gage, the gage installation, and times of operation with only 

 minor interruptions. Short interruptions in the operational status 

 of the gage are not mentioned. 



(b) Tables of overall annual and monthly maximums, mean and 

 standard deviations of significant height and peak period: The 

 monthly mean significant wave height and standard deviation, monthly 

 mean peak wave period and standard deviation, and the monthly extreme 

 significant heights are listed in these tables. Annual values and 

 statistics for the overall period are also included, along with the 

 total number of observations obtained for each month; at 4 observa- 

 tions per day, the maximum number of observations per month (based 

 on a 30-day month) is 120. From August 1978 to September 1979, 2 

 observations per day were recorded except during storms and special 

 events; 60 observations were recorded during a 30-day month. 



(c) Tables of joint distribution functions of significant height 

 versus peak period: For the overall time of operation of each gage, 

 joint distribution tables are presented which give the frequency of 

 the significant height and peak period within specified intervals, 

 based on the number of observations per 1,000 observations. These 

 values can be converted to percent by dividing by 10. The "row 

 total" gives the total number of observations per 1,000 observations 

 that fell within each specified significant height interval. The 

 "column total" gives the number of observations per 1,000 observa- 

 tions that fell within each specified peak period interval. Observa- 

 tions in the lowest peak period interval usually represented calm 

 conditions; however, these were not computed in the column total. 

 The "cumulative totals" in the table are cumulative totals of the 

 entries in the row total and column total. 



Each entry in the "row average" column is the average significant 

 height for all observations within each specified peak period inter- 

 val. Each entry in the "column average" is the average peak period 

 for all observations within each specified height interval. The row 

 and column averages are useful for investigating the relationship 

 between significant height and peak period.
