Bathymetry Inversion with Gravity-Geologic Method in Emperor Seamount
-
Abstract
The principle of bathymetry inversion with GGM method was discussed,the detailed calculate process was presented,and the bathymetry in south of Emperor Seamount was calculated.The accuracy of GGM bathymetry is better than ETOPO2 through the comparison with vessel depth data.Compared with classical methods,GGM method does not need to introduce a prior bathymetry model and take into account the isostasy of the seabed.The model is simple and easy to calculate.
