20. ABSTRACT (Continue on reverse side If neceaaary and Identity by block nutnber) 



The statistical variations in wave energy spectral estimates for hurricane 

 waves are examined empirically for 12 separate intervals of wave records 

 measured during Hurricane Carla in September 1961. Measurements were made on 

 a Chevron Oil Company platform in South Timbalier Block 63, Gulf of Mexico, 

 at a water depth of 100 feet. Hurricane waves were chosen for the analysis 

 because these waves show, in exaggerated form, the effects of departures from 

 linearit> on the statistical variability in spectral estimates.
