Wave Data Collection Sites

Since 1974 wave data have been collected at over 40 locations along the NSW coast using a variety of wave motion sensors. In general, the following instruments/applications are employed:

  • Directional Waverider buoys in deep or intermediate water depth to provide wave height, period and direction spectral information

  • Waverider buoys in deep or intermediate water depth to provide wave height, period and spectral information

  • Electromagnetic wave and tide monitoring systems (EWS) in shallow water to provide wave height, period, spectral and tidal information

  • from 1979 to 1989 Marsh McBirney and InterOcean S4 electromagnetic adaptive current meters were used to provide XY current information over the whole spectrum. The wave components are analysed and stored in a similar fashion to the Waverider and EWS data.


Table 1 provides a list of MHL offshore Waverider buoy stations. The buoys are typically moored in water depths between 60 and 100 metres between 6 and 12 kilometres from the shoreline. At the buoy location the water depth is sufficiently deep that wave refraction, diffraction, shoaling and friction attenuation effects are minimal.

In addition to the operation of offshore Waverider buoy network, MHL undertakes site specific wave data capture programs associated with particular projects, such as breakwater design/construction, harbour design/construction, beach erosion investigations, etc. The wave characteristics at these inshore locations may be significantly affected by refraction, diffraction, shoaling and friction attenuation. Table 2 provides a list of inshore wave data collection sites operated by MHL.
