Hi:
Classical tide gauges measure the height of the water relative to the gauge. But since the gauge is attached to a
tectonic plate it's elevation is changing.
This is one of the problems I have with the claim that sea level is rising at 2mm per year. i.e. how well can they back
out the plate movement in historical tide gauge records?
The new system uses a pair of GPS antennas one pointed up and the other pointed down at the water.
