Abstract
A032 Multiple diffractions and coherent noise in marine seismic data Abstract 1 The kinematics of both the primaries and the multiples (multiple diffractions) from sea-floor scatterers have similar characteristics when the sea floor is reasonably smooth and has only isolated irregularities. The multiple diffractions like the primary scattering are organised in mid-point gathers in such a way that mid-point stacking can enhance portions of the multiple. Also like the primary scattering the multiples can be distinguished from primary reflection events in the data by their dip in pre-stack shot and receiver gathers. Pre-stack dip-filtering in those domains can be used
