Low Cost Tide & Sea Level Measurements for Intertidal Public Safety

A recent NERC-funded proof of concept award successfully demonstrated that Global Navigation Satellite System (GNSS) signals reflected off the sea surface and received by very low cost (<£30) GPS receivers can be used to estimate the difference in height between the receiver and the water. This represents a method of remotely sensing tidal elevations and, if averaged over time, mean sea level. These could be routinely and remotely measuring sea level at a cost that would allow unprecedented numbers of systems to be deployed around the world by organisations of all sizes and levels of funding.
