We propose a method that begins by using the seismic data to calculate a sea surface profile. The sea surface profile is then provided to a modified linear Radon inversion scheme to model the receiver ghost. We compare receiver deghosting results using a flat sea surface datum and a variable sea surface datum using a deep water marine dataset. We show that receiver deghosting using a variable sea surface may improve wavefield separation; specifically, the clarity of the shallow reflectors is improved at the higher frequencies.
