It would help if we had some survey data of some sort to see what Iceman2020 is describing, whether a gravimeter can detect different densities of below-ground deposits. Happily, Tom has supplied a link to some: if you follow his link to the "SG Raw Gravity graph" etc, you can scroll down a little to a download of the full scientific paper – https://www.researchgate.net/publication/264122117_Detecting_small_gravity_change_in_field_measurement_Simulations_and_experiments_of_the_superconducting_gravimeter_-_IGrav/download
It's a very interesting read, investigating whether a superconducting gravimeter could be used to monitor in-ground storage of carbon dioxide for reducing global warming. The calibrating experiments include one where a heavy weight is placed directly above the gravimeter to see if any change in the downward, Planet Earth-induced force of gravity is found, plus another to measure any variation in gravity when the instrument is simply raised a short distance above the ground, but I won't spoil your enjoyment by posting spoilers. Suffice to say, the idea of Universal Acceleration struggles to explain the results found.
