description Apparatus and methods are described for attenuating noise associated with atmospheric pressure fluctuations in a seismic signal during seismic data acquisition using at least a pair of sensors comprising a seismic sensor and a pressure sensor for concurrently receiving a seismic signal and a pressure signal respectively, the sensors being adapted individually to transmit the respective seismic and pressure signals to a remote recording station which is adapted to record a plurality of seismic and pressure signals; and a filter for removing, at least partly, noise associated with atmospheric pressure fluctuations in the seismic signal, the filter employing an input signal from the pressure sensor; and a model of the coupling between the atmosphere and the ground to generate a reference signal which is combined with the seismic signal to produce an output signal.
