The lithosphere-asthenosphere boundary is the world’s most ubiquitous plate boundary system, separating the high viscosity lithosphere from the underlying convecting mantle asthenosphere. Thoroughly characterizing the …
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 climatic history of Mars has been indirectly studied through the remote detection of minerals produced by chemical alteration across its surface. While the martian …
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 …
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 …
Impact basins are unique crater landforms on planetary bodies, characterized by concentric topographic rings and radiating sculpture patterns. The onset of impact basins occurs at …
