The directional waverider measures the horizontal and vertical components of acceleration of the buoy, which rides up and down with the waves as it floats on the surface. The sampling rate is 1 Hz and the acquisition time is 20 minutes. From the accelerations of each acquisition time, spectra of energy by frequency and direction are derived. In addition, significant wave height and dominant wave period are calculated. The information is relayed to a shore data logging platform every 30 minutes. The Coastal Data Information Program (CDIP) are the primary stewards of the real-time data while UH handles maintenance duties.
