[0023] The reflection-based surveys described herein can obtain information about underground features. Acoustic signals can be reflected from underground lithological formations and acquired, analyzed, and interpreted. However, reflection-based surveys are generally not intended to provide information about underground features, but rather provide information about objects on the seafloor. For example, a pipeline located on the seafloor may be leaking fluid or gas at a location that may benefit from survey monitoring.

[0024] The present disclosure relates to systems and methods for seismic surveys. Using reflection-based surveys to detect and monitor objects on the seafloor can be challenging. Inefficiencies associated with increased survey times (such as greater risk of weather delays) increase the operating costs of these surveys and do not provide an accurate map of subsurface features of the seafloor other than objects located on the seafloor. In addition to monitoring objects located on the seafloor, the systems and methods of the present disclosure can also address these and other problems associated with performing surveys to detect subsurface features on the seafloor.

[0025] For example, a seismic survey system may monitor an object on the seafloor. The system may include a receiver array. The receiver array may include a first streamer and a second streamer. The seismic survey system may include a first plurality of receivers coupled to the first streamer and a second plurality of receivers coupled to the second streamer.

The seismic survey system may include a first lateral cable coupled to a first deflector and the first primary source. The seismic survey system may include a second lateral cable coupled to a second deflector and the second primary source.
