  • Augmenting and interpreting ice core greenhouse gas records

    Creator:
    Rosen, Julia L.
    Abstract:
    The three studies that comprise this dissertation seek to answer significant questions in paleoclimatology through unconventional applications of ice core greenhouse gas data. These studies involve different gases and span the interval of time between the Last Glacial Maximum and the Industrial Revolution, but are united by their nontraditional use...

  • Carbon cycle variability during the last millennium and last deglaciation

    Creator:
    Bauska, Thomas K.
    Abstract:
    The exchange of carbon on earth is one of the fundamental processes that sustains life and regulates climate. Since the onset of the Industrial Revolution, the burning of fossil fuels and anthropogenic land conversion have altered the carbon cycle, increasing carbon dioxide in the atmosphere to levels that are unprecedented...

  • The late holocene atmospheric methane budget reconstructed from ice cores

    Creator:
    Mitchell, Logan E.
    Abstract:
    Ice cores are considered the gold standard for recording past climate and biogeochemical changes. However, gas records derived from ice core analysis have until now been largely limited to centennial and longer timescales because sufficient temporal resolution and analytical precision have been lacking, except during rare times when atmospheric concentrations...

  • 10Be exposure ages of erratic boulders in southern Norway and implications for the history of the Fennoscandian Ice Sheet

    Creator:
    Goehring, Brent M.
    Abstract:
    This thesis focuses on the application of the cosmogenic nuclide Beryllium-10 (10Be) in an effort to better constrain the thickness history of the Fennoscandian Ice Sheet (FIS) at the Last Glacial Maximum (LGM) and into the Holocene, as well as begin to answer the long-standing question regarding the age and...
