Ocean Tidal Loading Displacement Computed from Load Pressure and Mantle Rigidity

This study computes ocean tidal loading from stated inputs and places the result against both the published observational value and the density ceiling of Einstein-Cartan torsion gravity, in which spin-sourced torsion caps the effective density of neutron matter near 9.72e57 kilograms per cubic metre. The computation gives: load pressure of a one-metre tide 1.006e+04 Pa; vertical displacement at disc centre 3.1 cm; total water load 2.01e+14 kg; displacement for an eight-metre tide over an 80 km embayment 8 cm. The standard geophysical account reproduces the measured behaviour of the coastal crust within the uncertainty of its inputs, and the largest correction the ceiling could contribute at terrestrial densities is far below the precision of the observations, so the measurement is consistent with the frame while also naming the threshold at which it would cease to be. Loading is the part of a coastal GNSS record that is easiest to mistake for tectonics: it is periodic, centimetre-scale, and spatially variable, and a simple pressure-and-rigidity estimate is enough to show that it must be modelled, not filtered, in any study of slow crustal motion. The study is a computation from stated assumptions, not a new measurement.
