Results

The wave height data from the wave gages were analyzed using a MatLab program which removes the trend out of the data and plots the surface displacement in time.  The program also determines the Number of Waves, Average Wave Period, Significant Wave Height, Maximum Wave Height, rms Wave Height, Average of Highest 1/10, and the Variance (Sigmaz).  The plots and the results for the MatLab program are shown below.
