Embodiments of real-time infill in marine seismic surveys using an independent seismic source are described. One method of seismic data acquisition includes acquiring primary seismic data at a plurality of streamers towed by an acquisition vessel based at least in part on energy emitted by a first seismic source, and towing an independent seismic source to acquire infill seismic data at the plurality of streamers based at least in part on energy emitted by the independent seismic source while the primary seismic data is still being acquired at the plurality of streamers based at least in part on the energy emitted by the first seismic source, wherein the independent seismic source is towed independently of the acquisition vessel.
