Device and method for denoising ocean bottom data

Computing device, computer instructions and method for denoising marine seismic data recorded with first and second seismic sensors. The method includes receiving (600) first seismic data recorded with the first sensor in a time-space domain; receiving (602) second seismic data recorded with the second sensor in the time-space domain; calculating (604) with a processor models of the first and second seismic data in a transform domain that is different from the time-space domain; performing a wavefield separation using the first and second datasets in the transform domain; determining (608) a noise in the transform domain corresponding to the second seismic data based on the wavefield separation; reverse (610) transforming the noise from the transform domain into the time-space domain; and denoising (612) the second seismic data by subtracting the noise in the time-space domain from the second seismic data.
