This provides measured tidal heights to a high degree of accuracy. A protective acoustic sounding tube and the tidal staff with a pressure sensor are mounted to a leg or pylon of a pier or stationary (non-floationg) dock that has been surveyed. The stations are designed to continue operating in extreme storms and to be highly reliable. In addition to measuring tidal heights these stations can record many different oceanographic and meteorological parameters. Some include wind speed and direction, water current speed and direction, air and water temperature, and barometric pressure.
