In this paper two sets of wave measurements made in the same region using a pressure transducer and a wave rider bouy are compared. The same methods of analysis were applied to both the records. The data overlapped over a period of six weeks with twenty minute records made at six hour intervals. Results obtained using zero-crossing analysis and spectral analysis using Fourier transforms were compared for the two cases: The probability distributions of wave heights and periods were compared in addition to examining the discrimination of the instruments to different wave periods. Finally the suitability of the two types of instruments for wave measurements is discussed by considering the different uses of the data.
