Patent ID: 6961284

Claim:
A marine seismic source comprising: a first array of N emitters of seismic energy, where N is an integer greater than one; and a second array of N emitters of seismic energy, wherein, in use, the first array is disposed at a first depth and the second array is disposed at a second depth greater than the first depth, the j th emitter of the first array (j=1, 2 . . . N) is displaced by a non-zero horizontal distance d H from the j th emitter of the second array along a first direction, and the j th emitter of the first array and the j th emitter of the second array both lie in a common vertical plane parallel to the first direction, wherein the horizontal displacement d H between the j th emitter of the first array and the j th emitter of the second array is substantially equal to a shot point interval of a surveying arrangement.
