Alkenones are lipids produced by certain haptophyte algae and are excellent sensors of temperature change. This dissertation investigates the stable isotopic and organic geochemical aspects …
Today, more than any preceding time, understanding the response of terrestrial ecosystems to changes in climate is imperative due to the extremes to which we, …
This thesis investigates the diversity and ecology of alkenone-producing haptophyte algae. Focusing on lake-dwelling haptophytes, this thesis describes the paleoclimate implications of haptophyte diversity. Additionally, …
Leaf wax D/H ratios are widely used to reconstruct environmental water D/H ratios in paleoclimatology. However, accurate quantitative assessment of precipitation D/H ratios from sedimentary …
The question of how to interpret precipitation isotope records in East Asia is an ongoing debate and has implications for understanding climate dynamics in East …
Ombrotrophic peatlands are a huge, largely untapped resource in the study of continental paleoclimate. In this dissertation I develop and implement novel proxies for climate …
