Abstract: 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.

Abstract: Marine survey data can be acquired at a tow line. The tow line is designed to be coupled between a marine survey vessel and a towed object. A receiver is associated with the tow line and designed to receive marine survey data at a location of the tow line. The receiver can be an optical fiber or other type of receiver.

Abstract: 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.

Abstract: Geophysical survey methods. At least some of the example embodiments are methods of performing a marine geophysical survey including: towing a plurality of sensor streamers behind a tow vessel, each sensor streamer coupled to the tow vessel by a respective lead-in cable; towing, by the tow vessel, a plurality of lead vessels with each lead vessel pulling a respective seismic source, each lead vessel pulled by a respective tow cable and at least one intermediate cable; actuating the respective seismic sources pulled by the plurality of lead vessels; and gathering seismic data by each of the sensor streamers.

Abstract: Geophysical survey systems and methods. At least some of the example embodiments are systems including: a tow vessel with an onboard data acquisition system; a sensor streamer that defines a proximal end and a distal end, the sensor streamer extends behind the tow vessel, and the sensor streamer submerged in the body of water; a lead-in cable coupled on a first end to the tow vessel, and coupled on a second end to the sensor streamer; a lead vessel associated with the sensor streamer, the lead vessel floating at or near the surface of the body of water, and the lead vessel coupled to the sensor streamer by a tow cable; and a seismic source in the water behind the lead vessel, the seismic source coupled to the lead vessel by a source cable that extends from the lead vessel to the seismic source.
