Directional Wave Measurements

Our SonWave-Pro wave spectra software package uses the proven PUV method for directional wave measurement. This method requires accurate measurement of pressure (P) and horizontal velocities (UV) at data rates high enough to resolve wave energy (typically 2 Hz or higher).

Most of our instruments (ADP, ADV, Hydra, PC-ADP, Triton-ADV) allow you to collect the data needed for directional wave measurements. In some cases, upgrading the capabilities of an existing system is fairly simple and does not require the return of the system to SonTek.

Directional Wave System Requirements
ADV, Hydra, PCADP These instruments are already capable of the appropriate measurement rates. As long as the system has a pressure sensor, all that is needed is the PUV software package.
ADP To gather accurate velocity data at rates sufficient for directional wave analysis, the SonTek ADP uses a modified measurement strategy. Burst sampling of highly accurate short-range measurements for waves is interspersed with the standard current profiles. Frequently Asked Questions about Directional Waves for ADPs/ADCPs
Triton-ADV The Triton-ADV is a directional wave, tide, and current measurement system that combines the power of SonTek's ADV technology with the proven PUV wave method. The Triton-ADV is the most value-packed system available for currents, directional waves, and tides.

The SonWave-Pro software package offers flexible processing schemes, custom plots (surface, polar, mesh), time-series displays, spectral displays, and wave statistics. The software can create publication quality graphics. Most of our instruments (ADP, ADV, Hydra, PC-ADP, Triton-ADV) allow you to collect the data needed for directional wave measurements.
