Method of cancelling turbulence noise in a fluid-filled seismic streamer

Turbulence (8) in a boundary layer on the outside of the streamer skin (3) in a seismic streamer results in the recorded signals from the hydrophones (2) in the seismic streamer being contaminated with noise. This is due to the fact that the turbulence noise is transmitted to the hydrophone's near field as an acoustic signal or via shear waves in the fluid filling (6). By deriving a transfer function for the transmission of the turbulence-generated noise and using of the transfer function on the recorded signal from the hydrophone (2), the turbulence-generated noise overlying a recorded signal can be cancelled.
