  • Understanding Signals of the South Pole Ice Core: Chronology, Climate, and Firn Processes

    Creator:
    Epifanio, Jenna A.
    Abstract:
    The South Pole ice core (SPC14), drilled in the field seasons of 2014/2015 and 2015/2016, is an intermediate length, 1,751-m ice core which preserves a 54,000-year record of past climate and atmospheric composition. The SPC14 ice core adds to the spatial grid of ice cores in Antarctica extending into the...

  • Interpreting Climate of the Past from High-Resolution Ice Core Records of Methane

    Creator:
    Lee, James E.
    Abstract:
    Methane is a product of biogeochemical processes which respond to changes in climate. The history of atmospheric methane is recorded by ice cores providing insight into past changes in these biogeochemical processes. This dissertation is comprised of three studies which focus on centennial- and millenial-scale variability of methane from ice...

  • 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...
