(2016-06-03)This dissertation presents advanced methods in data processing, statistical analyses, integration, and visualization of archaeogeophysical data to increase the accuracy of archaeological remote sensing interpretation and ...
-
(2021-05-04)Gravimetry, the measurement of slight variations in gravitational acceleration, can be used to infer density distributions and structures in the crust of a planetary body. The vast majority of studies on bodies other than ...
-
(2017-04-27)Extreme storms, hurricanes, nor’easters, and tropical depressions can cause widespread erosion and washover on barrier islands and threaten coastal communities. The strong winds and waves of these storms can erode the beach ...
-
(2019-02-21)ABSTRACT The Cascadia subduction zone hosts quasi-periodic, large-scale slow slip events which have been shown to be precursors to large, tsunamigenic earthquakes at other active subduction zone margins. Detection of these ...
-
(2020-01-30)Soil water availability influences the physiological, structural, and functional properties of plants. The physical properties of the soil play an important role in determining water availability, and shapes both the root ...
-
(2006-07-11)The spatial distribution of the melt phase can affect many properties of partially molten rocks, including viscosity and seismic wave velocity. A good way to quantify this distribution is the grain boundary wetness, the ...
-
(2013-12-02)This thesis explores the effects of fluid flow on shear localization and frictional strength of fault gouge through the use of a coupled 2-phase (pore fluid-grain) Finite Difference-Discrete Element Numerical model. The ...
-
(2018-11-16)The effective elastic thickness (Te) of the lithosphere is a geometric measure of its flexural rigidity and is determined by isostatic forces, crustal composition, thermal properties, and deformation history. As such, Te ...
-
(2014-08-01)A tensorial (9-component) controlled source electromagnetic survey over an oblique slip fault in Mason County, Texas was acquired and the data were analyzed in order to characterize the structure of the fault and observe ...
-
(Texas A&M University, 2005-11-01)The solution of the secondary coupled-vector potential formulation of Maxwell??s equations governing the controlled-source electromagnetic (CSEM) response of an arbitrary, threedimensionalconductivitymodelmust be ...
-
(2020-06-12)The formation and evolution of Mesozoic-age oceanic lithosphere documents the processes leading to the modern distribution of continents and ocean basins starting with the breakup of Pangaea, and plays an important role ...
-
(2016-08-02)The island of Bonaire is an isolated carbonate platform that is formed of Miocene to modern carbonate successions overlying a Cretaceous igneous basement. We show that the igneous basement of the island of Bonaire, Netherland ...
-
(2019-07-24)Carbonate rocks are a significant component of future petroleum endeavors, but due to complex pore geometries display a lower average recovery factor in comparison to sandstone reservoirs. To recover residual oil and gas ...
-
(Texas A&M University, 2005-11-01)A geophysical survey presents many challenges. A scientist must be able to not only understand the theory and nature of the geophysics being applied but must also be able to identify features of interest in a dataset. It ...
-
(2014-08-01)The Wavefront Construction (WFC )method, which was developed based on ray theory, is one of the most efficient tools in seismic modeling. The main idea of this method is to propagate a wavefront represented by rays in a ...
-
(2022-04-12)Rapidly acquired non-invasive geophysical data is key to reducing the risk inherent in subsurface investigations. It achieves this risk reduction by provision of spatiotemporally dense datasets and new methods to measure ...
