Wave data 



102. This section presents summaries from five wave sensors operated 

 during 1980. The annual and seasonal significant wave height and peak spec- 

 tral period statistics given below show a temporal and spatial variability of 

 the wave climate at the FRF. Additionally, Appendix B contains gage histories 

 and selected statistical summaries for each gage. 



103. The 1980 data summaries are more complete than those for 1978 and 

 1979 (see Miller 1982); consequently, more confidence can be placed in the 

 trends which are shown. 



104. The wave height statistics (see tabulation below) vary as a func- 

 tion of gage installation: as water depth increases, so does average annual 

 significant wave height. For example, the offshore Waverider buoy (gage
