Claim 17:
18. A marine seismic acquisition system for acquiring first and second seismic datasets to explore a subsurface with a shallow target resolution and with a deep target penetration, the system comprising:
a number n of source arrays that constitute a multi-source, wherein any two adjacent source arrays of the multi-source are separated by a distance D, each source array having a number m of sub-arrays, each sub-array having a plurality of source elements and a distance d between any two adjacent sub-arrays of a same source array among the n source array,
wherein a hexa-source is made of selected source elements from at least six different sub-arrays of the n source arrays,
first bins and the second bins associated with the first and second datasets acquired using the multi-source and the hexa-source, respectively, are defined on a surface of the subsurface and include reflection points of traces associated with the first and of the second seismic dataset, respectively, and
the distance d is selected so that first bins and second bins are interleaved.
