2Q. ABSTRACT fContfiouc am reveram a£^ ff f7*c««««rjr and Identify by block number) 



Wave measurements are examined from three relatively deepwater field sites 

 in Lake Michigan, the Pacific Ocean, and the Gulf of Mexico. Approximately 1 

 hour of data representing high waves, single-peaked spectra, and nearly con- 

 stant significant heights and peak spectral periods was selected for analysis. 

 The data represent actively growing waves at two sites and swell at the third 

 site.
