ABSTRACT:
A method and apparatus for marine seismic prospecting in which a long spacing linear array of seismic detectors is spaced from a seismic source and connected to a recording apparatus on a survey ship. A short spacing linear array of seismic detectors is also spaced from the seismic source and signals thereof supplied to suitable channels of the recording apparatus in common with some of the signals from the long spacing detector array. The principal and auxiliary signals in the common channels are distinguishable as a result of relative amplitude and time separation.
