Modeling, inversion and imaging of seismic data in viscous media
Real Earth media is anelastic, which affects both kinematics and dynamics of propagating waves. Waves are attenuated and dispersed. If anelastic effects are neglected, inversion and migration can yield erroneous results. The ...
Reflection coefficients for transversely isotropic media
Orientations of vertical fractures (i.e., transversely isotropic with axis of symmetry horizontal) can be detected using the Amplitude-Versus-Offset (AVO) response for the reflected p-waves. A MATLAB program that calculates ...
Three-dimensional finite-difference methods for seafloor scattering
For the purpose of simulating large-scale seafloor scattering for general heterogeneous media using an elastic finite-difference scheme, I develop new tools for modeling explosive point sources and pressure plane waves ...
Seismic facies investigation and late Quaternary glacial history of the Chilean shelf and fjords and Antarctic Peninsula fjords
High-resolution seismic data collected in inland waters Chile and the Antarctic Peninsula (41$\sp\circ$S-65$\sp\circ$S) were interpreted using seismic facies analysis. Piston cores provide some lithologic control on the ...
