Abstract
Summary
A method for attenuating strong, clustering turn noise, caused by the turning of seismic vessels in marine surveys, is proposed in this work. The critical step of this approach is based on a coherence-preferred anti-leakage Tau-P transform that fits input data by favouring coherent events and excluding strong, incoherent noise energy. After reconstructing the data from the Tau-P transform, most of the turn noise is attenuated.
