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 ...
Tests of an MHD code
A magnetohydrodynamics (MHD) computer simulation code is tested for numerical accuracy and physical plausibility. Comparisons are made between numerical results and simple linear theory. The adverse affects of numerical ...
Cenozoic inversion structures in a back-arc setting, Western Flores Sea, Indonesia
A geophysical and geological study utilizing high quality seismic and well log data was undertaken of a marginal basin in the Western Flores Sea, Indonesia, to document the evolution of Paleogene extensional basins and ...
Velocity analysis in the presence of uncertainty
Velocity analysis resolves relatively long scales of earth structure, on the order of 1 km. Migration produces images with length scales (wavelengths) on the order of 10's of m. In between these two scale regimes lies ...
A unified approach to complex seismic imaging problems
Two current challenges in seismic imaging are to obtain more detailed images of complex structures from reflection data and to constrain the regional structure of the Earth using wide-angle data. These are complex problems ...
Oblique collision and accretion of the Netherlands Leeward Antilles island arc: A structural analysis of the Caribbean-South American plate boundary zone
The Netherlands Leeward Antilles volcanic island arc is an ideal natural laboratory to study the evolution of the Caribbean-South American plate boundary. The Leeward Antilles islands (Aruba, Curacao, and Bonaire) are ...
