Abstract

A marine seismic source array includes multiple strings of marine seismic source elements. A first string has a first specified arrangement of air guns between a beginning of the first string and an end of the first string, A second string has a second, different specified arrangement of the air guns between a beginning of the second string and an end of the second string. The second arrangement is the reverse of the first arrangement. A specified arrangement of air guns may be defined, for example, by a number of air guns in each seismic source element, a chamber volume of each air gun, a spacing of the air guns, or any suitable combination of these and other parameters.
