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...

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...

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...
