Abstract
Methods and apparatus are described for reducing the multiple energy in seismic signal acquisitions, in particular for sea bottom acquisition. The method is based on the scattering Born series for free-surface multiples. It is characterized in that only terms of the even sub-series of the scattering Born series are considered for determining the multiple-free data.
