ABSTRACT:
In seismic exploration, particularly at sea, several seismic acoustic sources selected from different genera of such sources are combined in a single array. The several sources are fired substantially simultaneously so that the acoustic pulses from the several sources blend together to create a single composite seismic wave. The source genera are selected such that their initial impulses are in phase but their caudal transients are incoherent with respect to one another so that the initial impulse is enhanced at the expense of the after-pulses.
