Stable Isotope Constraints on Carbon Dioxide and Nitrous Oxide Variations at the Onset of the Last Glacial Period: New Ice Cores from Taylor Glacier, Antarctica

Creator:

Menking, James A.

Abstract:

New ice cores retrieved from the Taylor Glacier (Antarctica) blue ice area contain ice and air spanning the Marine Isotope Stage (MIS) 5/4 transition, a period of global cooling and ice sheet expansion. Chronologies were determined for the ice and air bubbles in the new ice cores by visually matching...

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...

Late Cenozoic Climate, Ice-sheet and Earth-surface Evolution Derived from Terrestrial and Marine Sedimentary Archives

Creator:

Bill, Nicholas S.

Abstract:

The goals of this dissertation are centered on understanding changes in Earth surface and climate systems through the use of geologic proxies as records of past changes in these systems. Specifically, this dissertation (1) establishes a new chronology for retreat of the Ross Sea sector of the West Antarctic Ice...
