Sea levels are bit tricky too. Currents and water temperature, density
and atmospheric pressure together with the phase angle between moon and
sun considerably distort the equipotential surface. As well as the
obvious twice daily tides the tidal range has roughly monthly periodicity.

All the more reason to have more than one brain going over the numbers.

Several ideally.
