  • Earthquake Relocation in Three-Dimensional Velocity Models for Central Cascadia Continental Margin

    Creator:
    Ghorbani, Paria
    Abstract:
    We used data from Cascadia Initiative and Blanco Transform Fault Zone array of ocean bottom seismometers and hydrophone to look at the seismicity and specially depth of the Central Cascadia Continental Margin events. Events were detected and located automatically with Antelope software package (Boulder Real Time Technologies). We looked at...

  • Hard spheres within classical density functional theory and Min proteins in Escherichia coli

    Creator:
    Schulte, Jeff B.
    Abstract:
    This thesis reports on computational research in two different areas. I first discuss the Min-protein system found within Escherichia coli. Following this I discuss an extended investigation into improving free energy functionals that are used within Classical Density Functional Theory in order to model water. Chapter 2 examines the dynamics...

  • Magnetotelluric Studies of Tectonic Systems and Volcanic Areas of North America

    Creator:
    Bowles-Martinez, Esteban
    Abstract:
    Magnetotellurics is used in two geologic settings on scales ranging from 1000-km tectonic structures to local features hundreds of meters wide. These areas are the Midcontinent Rift System (MRS) and its related mantle plume in the northern Midwestern United States and Newberry Volcano in central Oregon. The MRS study uses...

  • Interactions of wind-driven and tidally-driven circulation in the Oregon coastal ocean

    Creator:
    Osborne, John J.
    Abstract:
    Influences of tidal and slower (subtidal) oceanic flows over the continental shelf and slope off Oregon are studied using a high-resolution ocean circulation model and comparative model-data analyses. The model is based on the Regional Ocean Modeling System (ROMS), a fully nonlinear, three-dimensional model (using hydrostatic and Boussinesq approximations). The...

  • Paleomagnetic inclination shallowing in deep-sea sediments

    Creator:
    Arason, Pórdur
    Abstract:
    In this thesis anomalous downcore shallowing of paleomagnetic inclinations is interpreted to be caused by sediment compaction. Thus, compaction-induced inclination shallowing may influence tectonic reconstructions that are based on inclinations from deep-sea sediment cores. Progressive downcore shallowing of the remanent inclination was observed in a 120-m section of Plio- Pleistocene...

  • Ensemble-variational data assimilation for dynamically challenging coastal ocean circulation

    Creator:
    Pasmans, Ivo
    Abstract:
    Currently, forecasts produced by the Oregon-Washington (OR-WA) Coastal Ocean Forecast System are constrained by assimilation of only surface observations. The 4-dimensional variational (4DVAR) data assimilation (DA) algorithm is utilized to combine the model and the data, with the time-independent forecast ("background'') error covariance B. In this study, two possible improvements...

  • Source Parametrization of Earthquakes along Juan de Fuca Transform Boundaries

    Creator:
    Sapkota, Birat
    Abstract:
    The Juan de Fuca plate system is what remains of Farallon plate subducting under the continental North American plate. Blanco Transform Fault Zone (BTFZ) consists of a network of strike-slip faults discontinued by pull apart depressions which o↵sets the Juan de Fuca Ridge and the Gorda Ridge. Detailed analysis of...

  • Formal Verification of the Variational Database Management System

    Creator:
    Khan, Fariba
    Abstract:
    Variation in data is abundant and ubiquitous in real-world applications. Managing variation in databases is, however, difficult and has been extensively studied by the database community. Schema evolution, data integration, and database versioning are examples of well-studied forms of database variation with effective context-specific solutions. However, variation appears in different...

  • Investigation of Deep Seismic Reflections Beneath the Forearc in the South Central Chile Subduction Zone

    Creator:
    Zhang, Edward
    Abstract:
    The south central Chilean margin is one of the most seismically active subduction zones on Earth, generating some of the largest earthquakes on the planet, including the largest ever recorded in 1960 near Valdivia, Chile (Mw 9.5). Using the 15 km streamer and 6600 in3 tuned seismic airgun array aboard...
