  • Impact of Dansgaard-Oeschger and Heinrich Events on the Latitudinal Distribution of Methane Sources during Marine Isotope Stage 3

    Creator:
    Edwards, Jon S.
    Abstract:
    Understanding how the latitudinal distribution of methane sources changed between stadial and interstadial climate states during the last glacial period can provide important clues about how terrestrial hydroclimate and ecosystems evolved between these different states. The punctuation of the millennial-scale structure by Heinrich events is also of interest in this...

  • 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...

  • 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...
