The buoy is a 0.9 m metallic floating sphere with a combination of a bungee and chain anchoring system. The long-term availability of this mooring is uncertain. 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. Purpose: The wave data were acquired for application to physical models and near shore wave studies.

The discrepancy between vertical movement of the Waverider and the movement of the sea surface is small. When a moored Waverider follows the waves, the force of the mooring line will change. This force is produced by the changing immersion of the buoy, resulting in a error of max. 1.5%. With decreasing wave length, the buoy will not follow the wave amplitude if the wave length is less than 5m [wave period below 1.8 sec.]. If the wave length is less than 2.5m [wave period 1.25 sec.] the buoy's response decreases quickly. The directional Waverider measures wave height in the same manner as the Waverider. The directional wave measurements are calculated from the x, y, and z accelerations of the buoy.
