摘要： Acoustic source arrays and related methods. At least some of the example embodiments are methods including towing a first source sub-array comprising a first surface float, the first surface float defines a first connection point at a proximal end of the first surface float. The method may further include towing a second source sub-array comprising a second surface float, the second surface float defines a second connection point at a proximal end of the second surface float. And during the towing of the first and second source sub-arrays, the method may include maintaining a lateral separation between the first and second connection points of the first and second surface floats by a first strut, the first strut coupled between the first connection point of the first surface float and the second connection point of the second surface float.

摘要： A method for a marine seismic survey can include towing streamers that are spaced apart in a cross-line direction by a streamer separation (L) and towing seismic source elements that are spaced apart in the cross-line direction by a source separation based on an integer (k), an inverse of a quantity of the seismic source elements (1/S), and the streamer separation as represented by (k+1/S)L. The seismic source elements can be actuated and seismic signals can be detected at each of a plurality of receivers on the streamers.
