Aspects of the effective transversely isotropy (VTI) component of the oceanic anisotropy model from Data Source 3 is shown with the green dashed line. The red line is our revision of this model in which the moduli A and N are increased so that |$(A-C)/2C = (N-L)/2L = 7$| per cent and we tilt the elastic tensor through dip angle |$\theta = 45^\circ$|. (a) |$V_{SV} = L/\rho ^2$|. (b) Dip angle |$\theta$|. (c) S-wave anisotropy, |$\gamma = (N-L)/2L$|. (d) Ellipticity parameter |$\eta _X \equiv 4L/(A+C-2F)$|.
