We review the up-down (U/D) deconvolution and the more general multidimensional deconvolution (MDD) methods for source designature and attenuation of free-surface multiples recorded in ocean-bottom node seismic surveys. In spite of the theoretical limitation of stratified Earth, U/D deconvolution is known to perform well even for complex geology beneath a ‘flattish’ seabed. Examples are shown. MDD is analyzed to explain the good properties of U/D deconvolution.
