Hi, Kamron–
Give the poor workers a little credit. I rather expect they are well aware of
tidal influences and are compensating for them – this is too obvious to be
missed and any peer review would surely bury them deeper than the lithosphere
without it (hmm, what an opportunity for study… :). There might be room for
doubt about the exact method of compensation – but that is not going to make a
huge (even relative to what we are looking for) difference. I wonder what other
sources of systematic error there might be…
I don't know about inches, but GPS can be used with far more accuracy than
ordinary civilian devices permit if one has access to military equipment or a
reference station for differential measurements. I am sure the researchers
have at least the latter if they are using GPS – they would be laughed off the
plate without it.
