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...

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...
