Abstract

Our goal is to predict dynamic (shear velocity, attenuation) and physical properties (stiffness, density) of marine sediments from seismoacoustic records of surface waves propagating along the water-seabed interface. To estimate and invert propagational parameters of surface waves (group and phase velocity) into shear velocity as a function of distance and depth we use the wavelet cross-correlation technique [7]. In order to achieve a better resolution of imaging we developed a new data driven adaptive wavelet. Our approach is based on the Karhunen-Loeve decomposition (KL) of the data records. Obtained set of wavelets is naturally adapted to the surface wave modes propagation in terms of scales values: time and periods (frequencies). We show that the developed adaptive wavelet discriminates better between different surface wave modes than it can be achieved by using standard wavelets kernels.
