Abstract
We present a method of attenuating diffracted noise in marine seismic surveys. Such noise originates from heterogeneities near shallow sea beds. We locate position of such obstructions using semblance scan analysis, and then extract the noise from the traces at the calculated travel times for each diffraction trajectory. <br><br>
