A system and method are provided for substantially eliminating an influence of true azimuth three dimensional (3D) internal multiple reflections in determining undersea geography 5 in a geographical area of interest without a priori knowledge of subsurface information. The system and method define a set of upper windows that include a geographical area of interest, and a pair of lower windows that are below the set of upper windows, define a first set of apertures and a second set of apertures, segment seismic data to each of the windows using the first and second sets of apertures, and determine a total internal 3D multiple model based on an 0 iteratively generated internal 3D multiple model using the segmented seismic data. co cc cu "N CO ( 00 Nl CN N4 04C -- i N cuc -0 co )C |
