요약 | Inferring seafloor topography from gravity anomaly currently is the dominant method to obtain a global view of the oceans. This study deals with the methods of inferring this topography from gravity gradients, which is more sensitive to topograp |
요약 | The spectral domain method is based on the linear approximation to the Parker's infinite series, which is for the convenience of inversion the admittance that relates topography and gravity gradient. Only 15--160 km wavelength topography was est |
요약 | Through a numerical test, it was found that the nonlinear terrain effect was not negligible in rugged areas. Algorithmic analysis through the coherency showed that estimation accuracy at high frequencies cannot be improved by refining the resolu |
요약 | To remove the linear approximation in the modeled relationship between gravity gradients and topography, the simulated annealing, a global optimization technique that can process nonlinear inverse problems, was used to estimate the seafloor topo |
요약 | The simulated annealing approach developed in this study may be used to update the global seafloor model, especially in rugged areas. Besides, this approach has no restrictions on data distribution, as required in Parker's infinite series model, |
