Estimating subsurface structure through gravity and gravity gradiometry inversion
We use gravity to estimate rifted margin deep structure with an inversion method that links parameters in the shallow parts of the model to those in the deep parts through an isostatic, uniform extension model. The method ...
Retreat history of the last glacial maximum ice sheet in Ross Sea, Antarctica
High-resolution geophysical and geologic data were acquired in western and central Ross Sea, Antarctica, to determine the: (1) maximum extent and configuration of the ice sheet during the Last Glacial Maximum (LGM); (2) ...
Finite-difference seismic wave modeling including surface topography
I present synthetics of seismic wave propagation near free surface topography. The velocity-stress formulations of both the full elastic and viscoelastic wave equations are used, and I have derived exact boundary conditions ...
A study of seismic wave propagation in heterogeneous crust
Three different aspects of estimating properties from seismic data are treated in this thesis: (1) Deterministic processing of a high resolution shallow seismic data set with good geologic control, (2) traveltime estimation ...
Characterizing shallow aquifers with wave-propagation based geophysical methods: Imaging and attribute analysis
As the results of seismic reflection and ground penetrating radar (GPR) studies become more prevalent as input for quantitative groundwater and engineering studies, it is important to evaluate traditional approaches to ...
