This paper reviews some of the existing procedures used in the correction of seismic data. It concludes that a general lack of information on the correction processes used, with notable exceptions, when supplying CD-corrected data makes it difficult to draw conclusions on the reliability of the corrected data records. Of particular concern has been the possible corruption of phase data. The paper traces the development of the correction procedures and describes their rationale and methodology. The paper proposes modifications to the existing procedures and provides a software listing used in this study as a step in the interests of good practise in disseminating information on seismic correction. Moreover the paper proposes several metrics for judging the reliability of corrected data through the use of power spectral densities, phase spectra, coherence estimates, acceleration response spectra and the short-time Fourier transform and draws conclusions on the reliability of some of the correction procedures used.
