[more ▼] Advances in gravity instrumentation have allowed for the determination of the absolute acceleration of gravity to a precision of 3–5 μGal and observations of tidally driven changes in gravity on the order of nanogals. With observations of gravity and changes in gravity at these levels of precision we are able to investigate problems such as the resonance of the Earth's liquid inner core, to discriminate between the various ocean tidal models, understand the effects of atmospheric pressure loading on gravity observations, and perhaps to measure ice mass changes in Greenland. In this paper, we report on some of our results using absolute and superconducting gravimeter data. We describe a project to establish a site for international comparisons of absolute gravimeters in Luxembourg.
