Claim Text:
1. A method for determining a shallow water multiples model, the method comprising: generating a series of underwater seismic wavelets by one or more sources; acquiring seismic data from a plurality of receivers, and storing the seismic data; estimating a prediction operator by a shallow water demultiple (SWD) technique using the acquired receiver seismic data; generating a multi-channel water layer de-multiple (MWD) primary reflections model using the acquired receiver seismic data; and merging said SWD prediction operator with said MWD primary reflection model and with said acquired receiver seismic data to determine the shallow water multiples model, wherein the step of generating a MWD primary reflections model comprises: estimating a travel time of the transmitted seismic wavelets from one or more sources to each of a plurality of receivers; and generating the MWD primary reflection model using the estimated travel time and Green's function.
