- Аннотация: Combination of P-wave velocity analysis and AVA-study of seismoacoustic data can provide information about Vp, Vs, bulk density ρ and attenuation of the media. However, efficient AVA-analysis of ultra-high resolution dataset requires minor distortions in recorded signals. In this study, a specific field experiment with a deep-towed ultra-high resolution seismoacoustic system was conducted in order to minimize sea surface influence. Moreover, data were acquired using omnidirectional sparker source and hydrophone string to achieve accuracy in amplitude recovery. This allowed successful follow-up application of deterministic layer-stripping AVA-inversion for shallow subsurface. The approach is demonstrated on the White Sea field-data example.
