A Better Method for Calibrating a Tide Gauge

When conducting a hydrographic survey, the conventional method used to calibrate a tide gauge is to use a tide pole. The big disadvantage of doing it this way is that it usually requires someone to be on site for up to 26 hours, making it a labour intensive and expensive process.

iXblue has a much more efficient system for calibrating a tide gauge. Senior Surveyor Owen Friedlieb demonstrates the process, which involves deploying a GPS receiver inside a buoy, and explains the major benefits of doing it this way.
