  • Ocean Temperature Variability during the Late Pleistocene

    Creator:
    Hoffman, Jeremy Scott
    Abstract:
    This dissertation explores one overarching question relevant to the paleoclimate of the latest Pleistocene glacial cycle (approximately the last 130,000 years): “How did spatial and temporal evolution of ocean temperature, both at the surface and interior, relate to other parts of the climate system in the late Pleistocene?” Results from...

  • Modeling and dating glacier fluctuations and their relation to Pacific Ocean climate

    Creator:
    Anslow, Faron S.
    Abstract:
    This thesis presents the results of an investigation into the interactions between the present-day South Cascade Glacier and the former Mauna Kea ice cap at short (annual to centennial) and long (millennial and multimillennial) time scales. To quantify the response of South Cascade Glacier to atmospheric conditions, a surface energy...

  • Late Pleistocene and Holocene glacier and climate change

    Creator:
    Marcott, Shaun Andrew
    Abstract:
    This dissertation presents results from three studies that address major scientific questions in glacial geology and paleoclimatology for the late Pleistocene and Holocene using relatively new geochemical and statistical techniques. Each of the studies attempts to answer a longstanding question in the respective field using geochemical or statistical methods that...

  • Past climate variability in southwestern Oregon and relationships with regional and hemispheric climate

    Creator:
    Ersek, Vasile
    Abstract:
    This dissertation presents the results of three studies that assessed climate variability on short and long timescales in western United States. The growth of carbonate formations in caves (speleothems) is used to infer the timing and amplitude of past climate variability. We first assess the controls on speleothem growth for...

  • Analyzing large paleoclimate datasets : implications for past and future climate change

    Creator:
    Shakun, Jeremy D.
    Abstract:
    This dissertation presents the results of statistical analyses of large climate datasets from two time intervals – the 20th century instrumental record and the proxy record of the last deglaciation – in order to understand the forcings and mechanisms of past climate variability. A longstanding question in climate dynamics concerns...

  • Comparisons of teacher control ideology and student attitudes in elementary Christian schools

    Creator:
    Clark, Larry R.
    Abstract:
    This research project compared teacher attitude using the Pupil Control Ideology Form with student attitude using the Arlin-Hills Student Attitude Survey. P.C.I. Forms were collected from 834 teachers from 95 elementary Christian schools in several states. A total of 1074 student attitude surveys were collected from Christian school students in...

  • Hybrid computer simulation of wind-driven ocean currents

    Creator:
    Vithayathil, Francis Joseph
    Abstract:
    A simulation method using a hybrid computer is developed in this dissertation to enhance the study of wind-driven ocean circulation. The simulation is based on the mathematical model developed by Ekman. Pure digital simulation is not economical due to excessive computer time required for the solution of the partial differential...

  • 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...

  • An Interdisciplinary approach towards understanding late Pleistocene ice sheet change

    Creator:
    Cuzzone, Joshua K.
    Abstract:
    The results presented in this dissertation address a number of questions regarding late Pleistocene and Holocene ice-sheet and climate interactions, spanning disciplines involving paleoclimatology and atmospheric science. These studies use various techniques in geochemistry, climate modeling, and ice-sheet modeling to address ice- sheet response to climate and the attendant interactions...
