1. A system for attenuating coherent noise from seismic data, comprising:

  • one or more sensors configured to sense waves generated by a seismic source; and

    a coherent noise attenuation module comprising a processor and memory, the coherent noise attenuation module communicably coupled to the one or more sensors and operable to;

    receive a plurality of traces of seismic data from the one or more sensors;

    apply a first transformation to the plurality of traces of seismic data;

    identify one or more outlier waveforms in the transformed traces;

    attenuate the identified outlier waveforms; and

    apply a second transformation to the plurality of transformed traces,the second transformation being an inverse of the first transformation.
