The geology and geochemistry of the Sulphurets district porphyry Au-Cu-Mo deposits, British Columbia, Canada: Insights from a long-lived, gold-enriched porphyry district

Creator:: Campbell, Michelle E.
Abstract:: Porphyry Cu-(Au-Mo) deposits are critical sources of several economically important metals. The processes governing the total metal endowment and relative proportions of ore metals at these large magmatic-hydrothermal deposits remain uncertain. The Sulphurets porphyry district, in northwestern British Columbia, Canada, contains four porphyry Au-Cu-Mo deposits that each feature distinct Cu/Au...

Advancements in the Monitoring of Forests and Quantification of Live Aboveground Biomass Using Moderate Resolution Spaceborne Multispectral Imagery and Synthetic Aperture Radar Data

Creator:: Kilbride, John B.
Abstract:: The objective of this dissertation is to enhance the monitoring of forest ecosystems through the utilization of remotely sensed data to address the exigencies posed by the Anthropocene. On a global scale, rising temperatures and fluctuating precipitation patterns have strained forests and produced shifts in natural disturbance regimes. Additionally, the...

Investigating Influences of Natural and Anthropogenic Lead Sources on Environmental Archives at Multiple Spatial and Temporal Scales: Evidence from Oysters and Ice Cores

Creator:: Wensman, Sophia M.
Abstract:: Environmental archives provide records of natural and anthropogenic variation in the environment at different temporal and spatial scales. Lead (Pb) concentrations and isotopic ratios are useful tracers of anthropogenic emissions from industrial activities including mining, smelting, and leaded gasoline use, however, methods of measuring Pb are largely limited in low...

Unraveling the Diagenetic Cycling and Sequestration of Rare Earth Elements (REEs) in Marine Sediments to Understand REE Accumulation in Ancient Shales

Creator:: Yang, Jon
Abstract:: The rare earth elements (REEs) have been established as powerful tracers for a range of physiochemical processes occurring in the natural environment. They also hold significant economic importance as many technological advancements are reliant upon the REEs for their unique magnetic, luminescent, and electrochemical characteristics. In sedimentary settings, understanding the...

Exploring the Relationships Between Stable Water Isotope Ratios and Large Scale Atmospheric Circulation in Paleoclimate Settings Using an Isotope-Enabled General Circulation Model

Creator:: Niezgoda, Kyle
Abstract:: Climate model simulations and paleoclimate proxies are two tools that enable an understanding of the climate history of the Earth. When utilized together, they form a powerful paradigm for understanding past changes. Proxies are the only physical link to the past conditions on Earth, and models “fill in the gaps”...

Dose of reality : what can we learn from educational and veterinary pet owners to guide more effective environmental stewardship of pharmaceutical and personal care products (PPCPs)?

Creator:: Lam, Jennifer
Abstract:: Improper disposal of unused human and pet pharmaceuticals and personal care products (PPCPs) are an emerging public and watershed health threat around the world. Although some waste stream reduction programs such as PPCPs "take-back" exist, there is limited research in current programs on reducing the entry of PPCPs into the...

Hydrodynamic and Morphologic Controls on Extreme Coastal Total Water Levels Across Regional and Local Scales

Creator:: Serafin, Katherine A.
Abstract:: Coastal and estuarine flooding and erosion events are usually driven by the cumulative effect of multiple individual processes like waves, streamflow, storm surge, and/or tides. This dissertation focuses on separating the influence of the regional and local-scale geomorphologic and hydrodynamic processes driving variability in the magnitude and impacts of extreme...

Understanding Signals of the South Pole Ice Core: Chronology, Climate, and Firn Processes

Creator:: Epifanio, Jenna A.
Abstract:: The South Pole ice core (SPC14), drilled in the field seasons of 2014/2015 and 2015/2016, is an intermediate length, 1,751-m ice core which preserves a 54,000-year record of past climate and atmospheric composition. The SPC14 ice core adds to the spatial grid of ice cores in Antarctica extending into the...

Deciphering Quaternary Geomagnetic, Glacial, and Depositional Histories Using Paleomagnetism in Tandem with Other Chronostratigraphic and Sedimentological Approaches

Creator:: Reilly, Brendan T.
Abstract:: Stratigraphy and chronology are essential to sedimentological study of Earth system histories. And, stratigraphy and chronology are often challenging and interesting problems themselves. The Quaternary (2.588 Ma - present) experienced paleoenvironmental and paleo-geomagnetic variability well outside the range of the recent instrumental record, providing the opportunity to place recent observations...
