A method of monitoring the quality of data comprises sampling a data trace to determine the amplitude of the trace. Attributes that are indicative of the noise content of the data trace are then determined from the sampled amplitudes of the first data trace. The noise attributes of a particular data trace can be compared with pre-set threshold values or with the attributes determined for another data trace, thereby providing a method monitoring the quality of the data. The sampling process is performed in the time domain, and requires only a small amount of computation. The quality control can therefore be carried out on-line, so that the quality of the data can be monitored as it is acquired. The method can be applied to the quality control of seismic data.
