Continued development of organic geochemical proxies for paleoclimate reconstructions are proving invaluable for understanding climate dynamics and climate-ecosystem interactions. Here I investigate the utility of …
Forty two distinct Pleistocene age surface temperature reconstructions from the geological record were synthesized into one standardized dataset for comparison with model-derived surface temperature estimates …
Pleistocene age surface temperature reconstructions from the geological record were synthesized into one standardized dataset for comparison with model-derived surface temperature estimates using the CCSM3 …
Climate variability in the Indian Ocean region affects the livelihoods of billions of people. Paleoclimate reconstructions can provide critical insights into the fundamental oceanic-atmospheric processes …
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, …
The Songliao Basin in Northeast China contains one of the most complete terrestrial sedimentary records of the Cretaceous and represents an important terrestrial paleoclimate archive. …
The past one million years encompasses major changes in the Earth’s glacial-interglacial cycles, with a shift from 41- to 100-kyr during the Mid-Pleistocene Transition (MPT) …
Understanding the characteristics and drivers of climate variations is imperative to advancing our knowledge about the evolution and changes of the Earth system. The Holocene …
Tropical ocean upwelling zones like the eastern equatorial Pacific (EEP) Ocean regulate global climate by absorbing heat and carbon dioxide from the atmosphere. The influx …
The Pliocene (5.33-2.58 million years before present (Ma)) is the most recent epoch of Earth’s history when atmospheric pCO2 levels were as high as the …
Tropical African mountains are particularly sensitive to current and future climate change. Reconstructions of past variations in temperature and precipitation in tropical Africa are useful …
The Indian Summer Monsoon (ISM) is vital to over one-fifths of the world’s population who depend upon monsoonal rains. Recently collected marine sediment cores offer …
