Keywords: load amplitude delta factors, load Love numbers, oceanic gravimetric effect
Аnnotation: The implications of a broad set of factors for the oceanic gravimetric effect are estimated. These factors include dissipation, mass correction, the choice of the oceanic tidal model and Earth density model, the abandonment of considering the near-field zone, the allowance for the ellipticity of the Earth and relative, Coriolis, and inertial accelerations. It is shown that under the present-day requirements to the accuracy of the computations, it is the integral effect of these factors rather than the influence of each of these factors alone that largely governs the oceanic gravimetric effect. The load Love numbers up to order n =50 000 are calculated.
