Real-time knowledge of the directional spectrum and other statistical properties of the wave environment in coastal waters and harbors is critically important information for those involved in marine operations. Historical and real-time wave and tide statistics are also important for coastal engineering applications and for investigations of coastal processes. The spectral and statistical properties of the wave field can be calculated from accurate time-series of "triplet" measurements, either the three horizontal and vertical components of the velocity or the pressure and the two horizontal components of the velocity. MAVS-4WTG can make the necessary velocity vector and pressure measurements. Additionally, MAVS-4WTG can telemeter the measurements to shore in real-time and/or store them internally for later processing.

The need of marine operations personnel, coastal engineers, and oceanographers, however, is for reliable, automated calculation of the spectrum and statistics from the measured time-series. The ability to intervene manually is desirable, but a compulsory assessment at each processing step is not. Because marine operations personnel must make decisions in real-time, it is also important that the calculation is fast and that the results are presented in an easily interpreted form. NOBSKA has developed MWAVES directional wave spectra software to address these needs.
