1. A method for attenuating noise in marine seismic signals, comprising:

  • cross ghosting pressure responsive marine seismic signals acquired by deploying pressure responsive sensors in a body of water, and contemporaneously acquired motion responsive marine seismic signals acquired by deploying particle motion responsive sensors in a body of water, the signals acquired in response to actuation of a seismic energy source in the body of water;

    determining a difference between the cross ghosted signals; and

    using the difference to attenuate substantially horizontally propagating noise in at least one of the pressure responsive signals and the motion responsive signals.
