Abstract

A technique includes receiving a pressure measurement and a particle motion measurement from at least towed seismic sensor. The pressure measurement contains signal and noise. The technique includes estimating the signal in the pressure measurement and based at least on the estimated signal in the pressure measurement, estimating a noise in the pressure measurement. Noise in the particle motion measurement is predicted based on at least the estimated noise in the pressure measurement, and the particle motion measurement is processed to remove noise based on at least the predicted noise.
