“…At present, significantly more is known about attenuation of surface-related multiples ͑Anstey and Newman, 1966;Kennett, 1974;Aminzadeh and Mendel, 1980;Fokkema and van den Berg, 1993;Berkhout and Verschuur, 1997;Verschuur and Berkhout, 1997;Weglein et al, 1997 than is known about attenuation of internal multiples ͑Fokke-ma et al., 1994;Weglein et al, 1997;Jakubowicz, 1998;Kelamis et al, 2002;ten Kroode, 2002;van Borselen, 2002;Weglein et al, 2003;Berkhout and Verschuur, 2005;Verschuur and Berkhout, 2005͒. With the exception of techniques such as the angle-domain filtering proposed by Sava and Guitton ͑2005͒ and the image-domain surface-related multiple prediction technique of Artman and Matson ͑2006͒, the current state of the art in multiple attenuation involves estimating multiples in the data.…”
