ABSTRACT 



This report describes the development of and gives the 

 operating instructions for using the Electric Wave Staff 

 (Hydrographic Office Model Mark I). It combines the best 

 features of a step-resistance gage developed by the Beach 

 Erosion Board and the 50- Foot Spar Buoy Damping Disk 

 System developed by the University of California Fluid 

 Mechanics Laboratory. The gage has been developed for 

 making direct recordings of wave action in ocean areas 

 where the depth is greater than Vi wave length. The wave 

 staff has been modified to improve its watertightness, elimi- 

 nating the major weaknesses of the instrument in the past. 

 Consideration is being given to adapting the instrument for 

 use with a radio-buoy link.
