Abstract

In Denmark, vibroseismic data acquisition is commonly used for mapping groundwater reservoirs. A significant part of the reflection seismic profiles are acquired on asphalt roads, which makes the data very exposed to traffic noise. Normally, several sweeps are carried out at each source location. This gives an option for suppressing traffic noise on uncorrelated data. The method assumes that the vibroseismic source signal shows high repeatability in terms of both amplitude and phase. In this context, noise problems from cars and pedestrians will be addressed, but the present procedure is capable of suppressing any kind of noise that is non-repeating and reasonably localized in space and time. The method is simple and robust. It improves signal-to-noise ratio and reduces the need for manual trace editing when processing the data. Thus, by addressing the problem before correlation, significant improvements in the noise suppression can be achieved.
