2Qv ABSTRACT CCanfbxue am r^veran sfoto ff ii ^i ^ea aa ry aad Identify by block number) 



This report discusses a directional wave gage consisting of one absolute and 

 four differential pressure transducers. The differential pressure gage (DPG) 

 development and field testing at the Coastal Engineering Research Center Field 

 Research Facility pier at Duck, NC, is discussed and data analysis software 

 programs presented. The development of the first nine Fourier directional 

 coefficients from a four-gage pressure sensor array and the first eleven or 

 twenty-one coefficients from a five 'gage DPG is discussed.
