1. A seismic survey system, comprising:
a main source array comprising a first main source and a second main source;
an accessory source array comprising a first accessory source and a second accessory source, the first accessory source to couple with the first main source and the second accessory source to couple with the second main source, wherein the first main source comprising a first float of the first main source, a second float of the first main source, and a third float of the first main source, wherein the second main source comprising a first float of the second main source, a second float of the second main source, and a third float of the second main source, wherein the first accessory source is coupled with the first float of the first main source and the second accessory source is coupled with the first float of the second main source, and wherein a distance between the first main source and the second main source is between 50 m and 70 m; and
a data processing system having one or more processors, the data processing system is configured to:
initiate a first source shot of the first main source at a first frequency;
initiate a first source shot of the second main source at the first frequency;
initiate a first source shot of the first accessory source at a second frequency; and
initiate a first source shot of the second accessory source at a third frequency, wherein the first frequency is different from the second and the third frequency, and wherein the second frequency and the third frequency have same range.
