Risky business : evaluating the vulnerability and impacts from simulated oil spills in the Gulf of Mexico

Creator:: Nelson, Jake R.
Abstract:: Exploration and production of oil in the Gulf of Mexico has seen an astonishing increase since the first well was drilled in 1936. Much of the current exploration is occurring in waters greater than 5000 feet. The largest and most unprecedented oil spill in the United States occurred on April...

Enhancing Small Sample Foraminifera Analysis through Innovative Mass Spectrometry Techniques: A Pathway to Deeper Paleoceanographic Insights

Creator:: Meyer, Grace
Abstract:: Stable oxygen and stable carbon isotopes of foraminifera are widely applied in paleoceanographic reconstructions. Oxygen and carbon isotopes are typically measured using pooled sample analysis (i.e., the combination of several shells) or single-shell analysis (typically restricted to heavier shells that weigh above 10 µg). With pooled sample analysis, where many...

Investing upstream : a social-ecological systems perspective on water utility investments in ecosystem services

Creator:: Bennett, Drew E.
Abstract:: The concept of ecosystem services broadens perspectives on nature to include not only intrinsic value but also the utilitarian value it provides to society. Viewing nature through this lens informs our understanding of how particular ecological processes benefit different actors. In this research, I examine how water utilities in the...

Physical factors affecting the spatial distribution of infaunal bivalve assemblages and species along the continental shelf of the Pacific Northwest

Creator:: Labou, Stephanie Grace
Abstract:: The spatial distribution and abundance patterns of benthic infauna result from interactions with a host of environmental variables including sediment characteristics (percent silt-clay, grain size, total organic carbon), depth, temperature, and dissolved oxygen. This thesis focuses on the association of bivalve assemblages and species with potentially influential environmental variables along...

Investigating the Paleoseismic Potential of Small, Southern Cascadia Lakes

Creator:: Ross, Ann Elizabeth Morey
Abstract:: Marine and coastal sedimentary archives show that the Cascadia Subduction Zone can generate great earthquakes of ~M9, most recently in 1700 CE, yet we still know little of the impacts of these events inland of the Pacific coast. Inland lakes have recently been exploited for their use as paleoseismic records...

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...

The Effects of the Flow Regime on Stream Channel Form and Processes

Creator:: Hempel, Laura A.
Abstract:: Numerous studies have explored how alluvial channel size and morphology are adjusted to different sediment and flow conditions, yet we still know very little about how and to what degree the flow regime controls channel form and processes. We use the term ‘channel form’ to refer to the size and...

Petrogenesis of the Steens Basalt : Variation in Source Contributions and Effects of Crustal Passage During the Onset of Columbia River Flood Basalt Volcanism

Creator:: Moore, Nicole E.
Abstract:: Continental flood basalts represent short-lived but immense blasts of mafic magma to the continental crust. The youngest and smallest continental flood basalt worldwide, the Columbia River Basalt, initiated with the eruption of the most mafic member, the Steens Basalt (~16.9 Ma). The Steens Basalt is exposed in southeast Oregon, southwest...

Modeling Forest Response to Changing Climate Conditions in Western North America

Creator:: Hawkins, Linnia R.
Abstract:: Forests play an integral role in the global carbon cycle, regulating the atmospheric CO₂ concentration by sequestering nearly one third of anthropogenic carbon emissions and storing carbon for centuries. Forest ecosystems are integrated into the culture, ecology, and economy of western North America, supporting wildlife habitat, local economies, recreation, and...

Nature for whom? How type of beneficiary influences the effectiveness of conservation outreach messages

Creator:: Batavia, Chelsea, Bruskotter, Jeremy T., Jones, Julia A., Vucetich, John A., Gosnell, Hannah, and Nelson, Michael Paul
Abstract:: In recent years the conservation community has engaged in debate over value in nonhuman nature, especially as it relates to motivations for conservation. Many have expressed the assumption that more people are willing to support conservation when emphasis is placed on the human benefits of nonhuman nature, rather than the...
