Home  Education  Tides and Water Levels  How are Tides Measured? - The New System
  << Back While similar in  design to older tide houses, these newer enclosures are designed to  protect sensitive electronics, transmitting equipment, and backup power  and data storage devices. The older stilling well has been replaced  with an acoustic sounding tube and the tidal staff with a pressure  sensor. The new field equipment is designed to operate with the highest  level of accuracy with a minimum of maintenance, transmitting data  directly back to NOAA headquarters for analysis and distribution.
