Layer-stripping reverse-time migration
Reverse-time migration has proven to be successful for structures with steep dips and strong velocity contrasts. Applying this algorithm to a large scale seismic model requires significant computational expense, particularly ...
Tectonic evolution of the south-central Caribbean based on geochemical data
Northern Venezuela consists of seven east-west trending tectonostratigraphic belts which are from north to south: Dutch and Venezuelan islands (DVI), Venezuelan platform, Cordillera de la Costa-Margarita terrane (CCMT), ...
Seismic waveform tomography with multicomponent data at a groundwater contamination site
This thesis develops an SH-wave version of frequency-domain, full waveform tomography, and applies it, together with traditional acoustic waveform tomography, to a multicomponent seismic data set acquired over a shallow ...
Tests of inter-hotspot motion and of hotspot motion relative to the spin axis
First, an updated Pacific paleomagnetic skewness pole for chron 32 (72 Ma) is presented. The updated paleomagnetic pole corrects for the spreading-rate dependence of anomalous skewness, a correction which hasn't been applied ...
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 ...
