FIELD: physics.
SUBSTANCE: invention relates to geophysics and can be used for marine seismic survey. Disclosed solution describes versions of real-time filling of data in marine seismic surveys using an independent seismic source. One method of recording seismic data includes recording primary seismic data on a plurality of seismic braids towed by a recording vessel, based at least in part on energy emitted by the first seismic source, and towing an independent seismic source for recording filling seismic data on a plurality of seismic streams based at least in part on energy emitted by the independent seismic source, at still recording primary seismic data on a plurality of seismic streams based at least in part on the energy emitted by the seismic source. Independent seismic source is towed independently from the recording vessel.
EFFECT: technical result is an increase in the accuracy and informativeness of the data obtained.
