Abstract: The invention provides a system (100) for marine seismic surveying, comprising a towing vessel (110) with a controller, a source array (120) and a receiver array (130) with several streamers (131). The source array (120) comprises n>4 identical subarrays (121) configured as at least (n−1) seismic sources S1, . . . , Sn-1, wherein adjacent subarrays (121) are part of at least two sources Si, Sj at different times.
