Abstract
Towed-streamer acquisition samples a narrow range of azimuths. We discuss the resulting sensitivity of such data to azimuthal velocity anisotropy. Correction for such effects, using either a residual moveout correction before migration or incorporating the anisotropy within the migration step itself, can significantly improve the imaging of the data.
