Abstract The response function between seafloor undulation and sea surface vertical gravity gradient anomalies is derived based on the response function between sea floor velief and sea surface gravity anomaly. Accordingly, a simulation research is carried out with Gaussian seamount model.The effects of lithosphere effective elastic thickness,crustal density and the truncation wavelength on predicted results are studied. Finally,a high accuracy bathymetry model was established from actual vertical gravity gradient anomalies data.
