A Limnological Examination of the Southwestern Amazon, Madre de Dios, Peru
(2012)This dissertation investigates the limnology of the southwestern Peruvian Amazon centered on the Madre de Dios department by examining first the geomorphology and then the ecology and biogeochemistry of the region's fluvial ... -
A Reconstruction of Precipitation and Hydrologic Variability on the Peruvian and Bolivian Altiplano During the Late Quaternary
(2012)The Peruvian/Bolivian Altiplano is an important hydrologic system for paleoclimate reconstruction because it is unique in its ability to record climate variability associated with the near-continental scale South American ... -
Amazon Climate Reconstruction Using Growth Rates and Stable Isotopes of Tree Ring Cellulose from the Madre De Dios Basin, Peru
(2009)The Amazon basin is a center of deep atmospheric convection and thus acts as a major engine for global atmospheric circulation. From this basin, one fifth of the world's freshwater flux is discharged into the Atlantic and ... -
An Analysis of the Distribution and Economics of Oil Fields for Enhanced Oil Recovery-Carbon Capture and Storage
(2012)The rising carbon dioxide emissions contributing to climate change has lead to the examination of potential ways to mitigate the environmental impact. One such method is through the geological sequestration of carbon (CCS). ... -
Beach and sea-cliff dynamics as a driver of long-term rocky coastline evolution and stability
(Geology, 2012)Rocky coastlines, with wave-battered headlands interspersed with calm sandy beaches, stir imaginations and aesthetic sensibilities the way few other landscapes do. Despite their prevalence (sea cliffs or bluffs are present ... -
Biomarkers of Exposure: Arsenic Concentrations in Keratin in Populations Exposed to Arsenic in Drinking Water
(2014)Arsenic (As) exposure via groundwater consumption is a global health problem affecting millions. Monitoring exposure is a key step in understanding and predicating future health outcomes. This thesis explores the relationships ... -
Changes in U.S. Residential Monthly Energy Use per Capita: 1990-2017
(2019)Residential energy consumption represents a large share of total end use energy and shows strong correlation with monthly cooling and heating degree days. This study focuses on quantifying temporal change in the relationship ... -
Characterizing European Dependence on Russian Natural Gas
(2022)Russia's war in Ukraine in 2022 has put a new spotlight on Europe's overall reliance on Russian energy resources. As the subsequent international sanctions and Russia's weaponization of energy have caused an energy crisis ... -
Convexity, Concavity, and Human Agency in Large-scale Coastline Evolution
(2014)Coherent, large-scale shapes and patterns are evident in many landscapes, and evolve according to climate and hydrological forces. For large-scale, sandy coastlines, these shapes depend on wave climate forcing. The wave ... -
Dynamic Life Cycle Assessment Modeling Approaches for Transboundary Energy Feedstocks
(2016)The rise of the twenty-first century has seen the further increase in the industrialization of Earth’s resources, as society aims to meet the needs of a growing population while still protecting our environmental and natural ... -
Evolution of Coastal Landforms: Investigating Sediment Dynamics, Hydrodynamics, and Vegetation Dynamics
(2018)Coastal ecosystems provide a wide range of services including protecting the mainland from the destructive effects of storms, nutrient cycling, water filtration, nurseries for fish and crustaceans, and carbon sequestration. ... -
Exploring the Lower Limb of the Atlantic Meridional Overturning Circulation
(2018)The Atlantic Meridional Overturning Circulation (AMOC) is characterized as a northward upper limb that carries warm near-surface waters from southern latitudes to the subpolar North Atlantic, and a southward lower limb that ... -
Exploring the Spatial Distribution of Marine Nitrogen Fixation Through Statistical Modeling, High-Resolution Observations and Molecular Level Characterization
(2019)Marine productivity is limited by nitrogen in a large portion of the global ocean. Marine nitrogen fixation, catalyzed by a select group of microorganisms called diazotrophs, converts nitrogen gas (N2) into bioavailable ... -
Forcing, Precipitation and Cloud Responses to Individual Forcing Agents
(2020)Previously, we usually analyze climate responses to all the climate drivers combined. However, the climate responses to individual climate drivers are far from well-known, as it is nearly impossible to separate the climate ... -
Fractures, Faults, and Hydrothermal Systems of Puna, Hawaii, and Montserrat, Lesser Antilles
(2010)The focus of this work is to use geologic and geophysical methods to better understand the faults and fracture systems at Puna, in southeastern Hawaii, and southern Montserrat, in the Lesser Antilles. The particular interest ... -
From Layered Intrusions to Mid-Ocean Ridges: The Petrography and Geochemistry of Basaltic Magmas
(2020)The geochemical evolution of basaltic magmas, in a variety of settings, has been the subject of countless studies. In some instances, basaltic magmas evolve to form economic transition and precious metal ore bodies. The ... -
From the River to the Sea: Modeling Coastal River, Wetland, and Shoreline Dynamics
(2017)Complex feedbacks dominate landscape dynamics over large spatial scales (10s – 100s km) and over the long-term (10s – 100s yrs). These interactions and feedbacks are particularly strong at land-water boundaries, such as ... -
Geochemical and Isotopic Characterization of Coal Combustion Residuals: Implications for Potential Environmental Impacts
(2012)Coal fired power plants are ubiquitous in the United States and most developed countries around the world, providing affordable electricity to consumers. In the US, approximately six hundred power plants generate 136 million ... -
Glacial North Atlantic Millennial Variability over the Last 300,000 Years
(2008-11-26)The hematite-stained grain (HSG) proxy method, commonly employed by the late G.C. Bond to detect the "1500-year cycle" in North Atlantic climate, is reproduced and verified for the first time. The exact method is compiled ... -
Global Energy Systems and International Trade
(2020)This dissertation is a collection of studies at the intersection of global energy systems and international trade. In the first study (Chapter 2), we estimate the sensitivities of primary energy exports to disruptions through ...
