A method of compensating for seismic receiver motion in a marine seismic survey wherein at least one receiver (14) is towed behind a moving seismic vessel (10) comprises producing an acoustic energy wave at a seismic source (16), and recording the reflection arrival time t2 of the acoustic energy wave at the one receiver. The offset x between the source and the one receiver is determined. The normal moveout velocity VB for the acoustic energy, and the velocity VB of the seismic vessel, are also estimated. A corrected reflection arrival time t1 of the acoustic energy wave is then determined by applying a time correction to the recorded reflection arrival time t2. The time correction is a function of the offset x, the normal moveout velocity V, and the velocity VB of the seismic vessel. The method is applicable to a plurality of receivers, whether the receivers are arranged in a single sensor acquisition system or hardwired to form receiver groups.
