Tidal Data Service

Complementing hydrographic surveying, tidal data information is collected, measured and managed by HydroSurvey Australia. Tide gauges have been established at all standard ports in South Australia. The measurements recorded are supplied to the National Tidal Centre of the Bureau of Meteorology for the calculation of tidal predictions for subsequent years.

Tide books containing tidal predictions are jointly published with the South Australian Department for Transport, Energy and Infrastructure to assist local mariners, fishermen and boating enthusiasts.

An Acoustic Doppler Current Profiler (ADCP) unit is used to record wave heights and current flow throughout the water column. It has been used to measure the movement of coastal sands and assist in marine dredging operations by determining the current flow through shipping channels.
