Abstract:This report provides a preliminary evaluation of the seismometer wave gage system developed by Oregon State University (OSU). The background and theoretical basis for the OSU system is reviewed. An empirical evaluation iS obtained by comparing Yaquina Bay seismometer analyses with data from a pressure gage in the same area during 22 February to 5 March 1984. The pressure gage was funded by the US Army Engineer District, Portland. The OSU system appears to be well suited as a sea state indicator for real-time operational purposes. The system has inherent limitations, particularly for estimating wave period. Comparisons with the pressure gage indicate significant wave heights from the seismometer system are relatively reliable. The correlation coefficient is 0.98, and the mean significant heights differ by 8 percent. Suggestions for improving the seismometer system are provided.
