The Aki, Richards and Frasier approximation is appealing because it is written as three terms, the first involving P-wave velocity, the second But a (no doubt) tivity, we apply the approximations of Aki and Richards (1980), Shuey (1985), Smith and Gidlow (1987), Wang (1999), and Fatti (1994), and the anisotropic approximation of Rüger (1976) is con-sidered for englacial reflectivity. highest honor (the Bowie medal), Willie Lee and John McRaney Regrettably, as indicated above, we accumulated some 6. This page details bibliographic information and reader notes on a citable Book that we have found to be relevant to one or more of our Research Projects. Several attempts have been made to develop approximations to the Zoeppritz equations, such as Bortfeld's (1961) and Aki & Richards’ (1980), but the most successful of these is the Shuey's, which assumes Poisson's ratio to be the elastic property most directly related to the angular dependence of the reflection coefficient.
