Multiple Attenuation of Multicomponent Ocean-Bottom Data According to an Elastic Model

In multicomponent ocean-bottom acquisitions, hydrophone data is acquired together with vertical and horizontal geophone data. The pressure and vertical velocity measurements are contaminated by ghosts and peg-leg multiples and must be merged for water-lager multiple attenuation. In this paper, a method is presented for water-lager multiple attenuation which takes into account nonvertical propagation and the elastic nature of the water-bottom without requiring the subsurface elastic parameters to be known, nor the measurements to be well calibrated.
