Analysis of the application of collision cross sections and ion neutral reaction rates in the upper atmosphere modeling
(2000)
Review and analysis of atomic collision data (such as collision cross sections and ion-neutral reaction rates) used in the upper atmospheric modeling for Earth and other planets are presented. This work gives the first ...
Seismic waveform tomography with multicomponent data at a groundwater contamination site
(2009)
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 ...
Diffuse oceanic plate boundaries: Kinematic observations and rheological constraints
(2006)
We use a thin viscous sheet model to interpret the observed shortening along a seismic reflection profile collected on the Phedre cruise (on the deforming oceanic lithosphere in the central Indian Ocean). We determine the ...
Revised estimates and uncertainties of motion between hotspots: Implications for the global plate circuit
(2005)
New quantitative methods of determining plate motions with respect to the hotspots, and their associated uncertainties are presented. These methods are then applied to Pacific hotspot data and combined with the global plate ...
Holocene evolution of the Matagorda/Lavaca Bay complex, central Texas coast
(2006)
The evolution of the Matagorda/Lavaca Bay complex demonstrates that although eustasy was an important control on incised valley flooding during the Holocene, antecedent topography, climate change, and barrier migration ...
Late Oligocene and Miocene evolution of the carbonate system in the Gulf of Martaban (northern Andaman Sea): Effects of eustacy, tectonics, and siliciclastic input; Comparison with the Maldives carbonate system
(2005)
Eustacy was the dominant factor influencing the Gulf of Martaban Field isolated platform, subdivided in Lower and Upper Martaban Limestones (LML) and (UML). LML was established on top of a faulted accretionary basement ...
Localized waveform inversion applied to the D" region in teleseismic imaging
(2009)
A localized waveform inversion technique based on hybrid modeling was developed to investigate the shear wave velocity structure of the lowermost mantle. Utilizing ray theory and the Kirchhoff integral, the source wavefield ...
Strength envelopes for deforming oceanic lithosphere with some implications for the history of lithospheric deformation of the equatorial Indian Ocean
(2009)
Strength envelopes for oceanic lithosphere inferred from laboratory experiments indicate that the oceanic lithosphere in the central Indian basin is several times stronger (≈27 TN m -1 ) than the force available to drive ...
Three-dimensional seismic structure of the Leeward Antilles arc from seismic refraction and refraction and reflection tomography
(2006)
We have developed new velocity and Moho interface models for the Dutch Antilles region of the Leeward Antilles arc from independent and simultaneous 3-D inversion of first arrival and PmP traveltimes. The first arrival and ...
