چکیده انگلیسی
With the progress in clock technology heading towards a relative clock accuracy of 10â18, geodetic applications become feasible, such as determining gravity potential differences over large distances at the level of 0.1â¯m2â¯sâ2. In this context, the effect of temporal gravity field variations on the new observable has to be considered. This paper studies non-tidal ocean loading effects on the gravitational potential around the North Sea with respect to signal strength and temporal behavior. Ten years of gravitational potential variations caused by non-tidal ocean loading are calculated for five locations in Germany and France using the Green's function approach. The potential variations are discussed with respect to a static gravity field, the effect of different measurement durations and the differences between two locations. The gravitational potential variations reach values of 0.2-0.5â¯m2â¯sâ2 in coastal areas and decrease with increasing distance from the coast. Analyzing the potential variations for increasing measurement durations from 1â¯h to 48â¯h shows a decrease in magnitude. All investigated locations are strongly correlated. They differ mostly due to different magnitudes of the gravitational potential variations.
