Geophysical study of deep-crustal structure: Mid-Atlantic passive continental margin
Migration results of two multi-channel vertical incidence reflection seismic dataset offshore Virginia are presented. A new velocity model derived from multi-channel and wide-angle reflection/refraction data is developed ...
Seismic facies investigation of the late Cenozoic glacial history of Bransfield Basin, Antarctica
Approximately 3000 km of high and intermediate resolution seismic data and 117 sediment cores were examined to reconstruct the late Cenozoic glacial history of Bransfield Basin, Antarctica. The complexity of a glacial ...
Finite element modeling of thrust faulting
Finite Element modeling of thrust faulting shows that the faults will propagate upward at very low angles from the leading edge of a regional horizontal decollement surface located at various depths in a homogeneous block ...
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 ...
Modeling electromagnetic fields of the earth's magnetosphere
The early version of the Toffoletto - Hill - Ding open magnetosphere model is improved and generalized in this thesis. This model computes the interplanetary magnetic field (IMF) dependent magnetic and electric fields in ...
On a transmission inverse problem
In crosswell seismic experiments, seismic sources are fired in one well, and the wave-fields generated are measured in another well. The goal of the crosswell seismology is to find physical parameters, especially the ...
