Seafloor-Consistent Multiple Supression , by Stewart A. Levin

Seabottom multiples and peglegs are predicted in a process that combines wave propagation and seafloor-consistent reverberation reflection filters. Key features of the method are: truly seafloor-consistent filters; incorporation of the pure seabottom multiple; fitting error minimized at the surface; and simultaneous design using all the recorded data. I use this process to suppress strong seafloor peglegs from dipping beds on a line from the Barents sea for which conventional multiple attenuation was ineffective.
