  • 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...

  • 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...

  • 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...

  • Investigation of Glacier Dynamics During the Last Glacial Maximum at Tioga Pass, Yosemite National Park

    Creator:
    Laub, Alexander G.
    Abstract:
    Previous investigations of glacier dynamics at Tioga Pass during the Last Glacial Maximum (LGM) have produced different conclusions. A map of the LGM ice extent and flow direction (Alpha et al., 1987) illustrates a south-to-north direction of ice flow across the pass with little evidence to support this inference. Since...
