This dissertation explores the recent history of non-polar ice-rich paleodeposits on Mars, primarily through the analysis of pedestal craters. Pedestal craters are defined by having …
Recent development of biomarker-based paleoclimate proxies provides new analytical capabilities through which paleoenvironmental change can be inferred. Here, I explore the utility of these organic …
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 …
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 …
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 …
Valley networks, many connecting voluminous paleolakes, dissect the martian highlands, but ceased activity ~3.7 billion years ago. The nature of the climate that allowed so …
Organic matter is present on many bodies in the solar system. The parent bodies of carbonaceous chondrite meteorites, for example, are known to contain a …
Over the coming century, global temperatures are expected to rise by 1.8°-4°C due to anthropogenic emission of greenhouse gasses. This increased radiative forcing and associated …
Knowing how the Earth system will respond to the human release of greenhouse gases (GHG) requires knowing something about how climate has responded to similar …
The atmosphere over the tropical Indonesian archipelago is highly convective and has high annual precipitation, giving rise to its widespread lowland evergreen rainforests. The region …
