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 …
The history of Mars’ paleoclimate is explored using sedimentary records from both the Noachian and Amazonian periods. Sedimentary structures indicative of a progradational delta are …
Under the current paradigm of Mars history, the planet is thought to have undergone a global climatic change, from relatively warm and wet conditions during …
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 …

This dissertation explores the historical determinants of comparative economic development. The first chapter examines theoretically and empirically the economic origins of ethnic and linguistic diversity. …
Recent climate extremes, including floods, droughts, and hurricanes, have had devastating effects worldwide, driving new research aimed at developing better prediction of such events. Understanding …
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 …
The nitrogen and oxygen isotopic composition of nitrate in ice cores offers unique potential for examining reactive nitrogen oxide (NOx) budgets and oxidation chemistry of …
Epidemiologic analyses of meteorological exposures typically apply data from the nearest airport weather observatory as the exposure metric for a population that may be distributed …
This dissertation explores three topics related to urban growth and economic development. The first chapter asks how transport costs to a port affect the level …
