  • An Evaluation of the Complex Age Progression along the Cook-Austral Islands Using High-resolution ⁴⁰Ar/³⁹Ar Incremental Heating Ages

    Creator:
    Rose, Joanna
    Abstract:
    The Cook-Austral island chain has been the center of debate for many years. Contrary to the classical hotspot hypothesis, this volcanic island chain does not exhibit a linear age progression with a single node of active volcanism, but instead shows evidence of young volcanism at several points along the chain....

  • Temporal Evolution of Submarine Volcanoes and Seamount Trails

    Creator:
    Schnur, Susan R.
    Abstract:
    The spatial distribution and geologic histories of submarine volcanoes provide insight into submarine eruptive behavior, deep earth processes and plate tectonics. This dissertation examines the evolution of individual submarine volcanic edifices as well as linear trails of seamounts at three spatial and temporal scales. In order to understand constructive and...

  • On the Volcanic and Geodynamic Evolution of the Shatsky Rise and the Louisville Seamount

    Creator:
    Heaton, Daniel E.
    Abstract:
    Large igneous provinces (LIPs) and intraplate seamounts reflect of anomalous mantle melting and illuminate interior processes of the Earth. These features are in all ocean basins and show the mantle’s evolution over time, then can provide information on plate tectonic processes, such as plate motion over time, spreading ridge formation,...

  • Using An Array of NE Pacific Margin Sediment Samples to Link Land and Ocean Responses to Glacial-Interglacial Climate Variability

    Creator:
    Wilson, Kiya L.
    Abstract:
    Variability in the terrigenous (land-derived) fraction of marine sediments, including pollen and rock fragments, reflects the effects of regional climate change on continentally derived runoff, ice extent, vegetation and ocean circulation. The transport of this continental material to the seafloor must be understood in order to interpret the terrigenous sediment...

  • New Insights into Mantle Dynamics from Helium Isotopes and Argon Geochronology

    Creator:
    Konrad, Kevin
    Abstract:
    Earth’s mantle extends to nearly 3000 km depth, comprises >80 % of Earth’s total volume, and has the largest influence on the primordial and radiogenic heat budget. Despite its importance, the structure and composition of the mantle is still debated. There are three primary models for Earth’s mantle structure that...

  • Three-Dimensional Network-on-Chip Architectures for Cycle Accurate Full-System Simulator

    Creator:
    Agarwal, Akash
    Abstract:
    High Performance Computing can find ubiquitous applications in the industry. HPC-applications are specifically designed to take advantage of the parallel nature of the computing systems which is often enabled by Multi-core/Many-core architectures. With this advent of Multi-processors in the mainstream systems, inter-core communication has been one of the major challenges...

    Creator:
    Kopper, Sarah
    Abstract:
    The World Health Organization (WHO) defines female genital cutting (FGC) as “all procedures that involve partial or total removal of the external female genitalia, or other injury to the female genital organs for non-medical reasons” (WHO, 2010). This practice has existed in Africa for thousands of years, but over the...

  • The marine geomorphology of American Samoa : shapes and distributions of deep sea volcanics

    Creator:
    Roberts, Jed T.
    Abstract:
    The geologic processes at work in American Samoa have long been a point of scientific debate. Of its numerous volcanic formations, few breach sea level, leaving an enormous proportion of their mass unavailable to traditional observation. This study aims to describe the deep sea geomorphology of American Samoa through compilation,...

  • Evaluating safety at Oregon‘s isolated, high-speed, signalized intersections

    Creator:
    Kopper, Neil H.
    Abstract:
    Isolated approaches at signalized intersections with posted speed limits of 45 mph or greater generally experience large numbers of rear-end and angle collisions. A combination of less attentive drivers, high operating speeds, and less than ideal intersection characteristics can result in crash frequencies well above expected rates. A number of...

  • Application of Cosmogenic Nuclides and Argon Geochronology to Paleoclimate, Paleomagnetism, and Paleohydrology

    Creator:
    Balbas, Andrea M.
    Abstract:
    This dissertation uses argon geochronology and cosmogenic nuclide surface exposure dating methods to address three research questions. The first question concerns a geomagnetic instability recorded in lava flows on the island of Floreana in the Galapagos Archipelago. Changes in the Earth’s magnetic field (intensity and orientation) occur frequently throughout geologic...
