Barbel Traub, Anh Kiet Nguyen, and Matthias Riede "Fast free-surface multiples attenuation work-flow for 3D OBS data" SEG Expanded Abstracts 25, 2664 (2006), DOI:10.1190/1.2370075
http://dx.doi.org/10.1190/1.2370075
Disclosing attenuation of free-surface related multiples for 2D and 3D Ocean Bottom Seismic data based on wave equation. Free-surface multiple attenuation is performed in the radon domain. Data are transformed into the Radon (-p-q) domain by means of a fast Radon Transform using Fourier projection slice theorem then, the wavefield is split into its up-and down-going part to create a deterministic deconvolution filter to identify & attenuate the energy of free-surface multiples.

B. L. N. KENNETT, "THE SUPPRESSION OF SURFACE MULTIPLES ON SEISMIC RECORDS"
http://www3.interscience.wiley.com/journal/119598632/abstract
Disclosing the suppression of multiples reflected at the surface of a horizontally layered fluid or elastic medium recorded at non-zero offsets from the source by extracting the effect of the free surface in the frequency-wave number domain and then replacing this surface with a non-reflecting boundary by a multiple suppression operator having detailed knowledge of the source time function and the elastic properties of the medium between the source and the surface.

http://casp.systekproof.com/papers/paperuu.pdf
Disclosing multiple attenuation of marine seismic reflection data combining conventional marine surface seismic reflection data (streamer data) to add the wave paths for multiple attenuation, resulting in multiple attenuation which takes into account all free-surface multiples including receiver ghosts and non-linear synthetic data.

Discloses removing free-surface multiples from transmission and constructed reflection responses, considering both the recorded waves under the real transmission geometry and synthetic constructed waves under a virtual reflection geometry.

discloses the use of the inverse source wavelet to provide an accurate estimate by a linear (least-squares) inversion process using an iterative multiple elimination process, together with the source wavelet estimation.
