Abstract: A marine seismic source includes source elements configured to emit waves having different frequencies while the source elements are towed at different predetermined depths, respectively. The predetermined depths are calculated such that water-surface reflections of the waves generated by a source element among the source elements interfere constructively with the waves generated by the source element and propagating toward an explored structure under the seafloor. The waves combine to yield a spike-like signature of the source.

The method for de-blending seismic data associated with a subsurface of the earth includes receiving initial seismic traces recorded by plural sources; de-blending, in a processor, the initial seismic traces to generate de-blended seismic traces; and generating an image of the subsurface based on the de-blended seismic traces.
