FIELD: geophysics.
SUBSTANCE: invention can be used in marine seismic survey operations. Invention provides system (100) for marine seismic survey, comprising towing vessel (110) with controller, group (120) of sources and group (130) of receivers (130) with several towed seismic cables (131). Source group (120) comprises n≥4 identical subgroups (121) configured in form of at least (n–1) seismic sources S1,... Sn-1, wherein adjacent subgroups (121) are part of at least two sources Si, Sj at different points in time.
EFFECT: technical result is an increase in the accuracy and informativeness of the data obtained.
