Concentration-Runoff Relationships of Contrasting Small Mountainous Rivers in the Pacific Northwest, USA: Insights into the Weathering of Rhenium

Creator:: Ghazi, Layla
Abstract:: This study examines dissolved rhenium (Re) as a function of water runoff using river samples from two contrasting watersheds, the Eel and Umpqua Rivers in the Pacific Northwest, USA. These watersheds share many key characteristics in terms of size, discharge, climate, and vegetation, but they have a 10-fold difference in...

Deeply dredged submarine HIMU glasses from the Tuvalu Islands, Polynesia: Implications for volatile budgets of recycled oceanic crust

Creator:: Jackson, M. G., Koga, K. T., Price, A., Koppers, A. A. P., Finlayson, V. A., Konrad, K., Hauri, E. H., Kylander-Clark, A., Kelley, K. A., and Kendrick, M. A.
Abstract:: Ocean island basalts (OIB) with extremely radiogenic Pb-isotopic signatures are melts of a mantle component called HIMU (high µ, high ²³⁸U/²⁰⁴Pb). Until now, deeply dredged submarine HIMU glasses have not been available, which has inhibited complete geochemical (in particular, volatile element) characterization of the HIMU mantle. We report major, trace...

Exploring the Magnetic Properties of Specific Grain-Sizes to Understand Marine Depositional Systems: A Case Study from the Eirik Ridge South of Greenland over the Last Glacial Cycle

Creator:: Freiberg, Benjamin T.
Abstract:: Disentangling sediment source from sediment transport is a fundamental marine geologic challenge critical to the interpretation of any sedimentary record. The Eirik Ridge, a sediment drift south of Greenland, receives terrigenous sediment primarily from subglacial erosion of south Greenland’s Precambrian bedrock and Paleogene volcanics that outcrop in east Greenland and...

Late Cenozoic Climate, Ice-sheet and Earth-surface Evolution Derived from Terrestrial and Marine Sedimentary Archives

Creator:: Bill, Nicholas S.
Abstract:: The goals of this dissertation are centered on understanding changes in Earth surface and climate systems through the use of geologic proxies as records of past changes in these systems. Specifically, this dissertation (1) establishes a new chronology for retreat of the Ross Sea sector of the West Antarctic Ice...

Impact of Igneous Mineralogy on the Composition and Metabolic Function of Microbial Biofilms in a Thermal Suboceanic Crustal Aquifer

Creator:: Smith, Amy R.
Abstract:: Igneous oceanic crust encompasses ~60% of Earth’s surface and is composed of basalt glass and mafic, ultramafic, and felsic minerals. A vast marine aquifer lies within the crust, exchanging geochemically altered fluids with seawater from the overlying ocean at ridge crests, flanks, seamounts, and outcrops where permeable crust is exposed....

Development and use of satellite-derived sea-surface temperature data for the nearshore North Pacific and Arctic Oceans : temperature pattern analysis and implications for climate change at ecoregional scale

Creator:: Payne, Meredith C.
Abstract:: The quantification and description of sea surface temperature (SST) is critically important because it can influence the distribution, migration, and invasion of marine species; furthermore, SSTs are expected to be affected by climate change. Recent research indicates that there has been a warming trend in ocean temperatures over the last...

How well do American viticultural areas correspond with the soil classes in Oregon's northern Willamette Valley? A question for the wine industry

Creator:: Wood, Douglas T.
Abstract:: The specific geography of individual wine growing regions has long been understood to be a significant factor in predicting both a region’s success in producing high quality grapes, and the resulting demand for wines produced from that region's fruit. In the American wine industry, American Viticultural Areas (AVAs) are increasingly...

An Experimental Investigation of Interstitial Air Movement in Seasonal Snow

Creator:: Drake, Stephen A.
Abstract:: Atmospheric pressure changes do not stop at the permeable snow surface but rather propagate into it. These pressure changes range from high-amplitude, low-frequency events caused by seasonal cycles and synoptic weather systems to small-amplitude, high-frequency events caused by topographic features and turbulence. The effect of pressure changes on interstitial air...

Horizontal Variability of Internal Waves and Tides: Seafloor Pressure Measurements and Idealized Resonant Modes

Creator:: Thomas, Jennifer A.
Abstract:: Internal waves and tides are a dominant source of current variability, and they are intermittent and hard to predict. Internal waves can have significant variability in alongshore structure. However, previous studies on internal waves have focused primarily on their cross-shore structure and propagation. For example, while alongshore-propagating superinertial internal tides...

Geochemical evidence in the northeast Lau Basin for subduction of the Cook-Austral volcanic chain in the Tonga Trench

Creator:: Price, Allison A., Jackson, Matthew G., Blichert-Toft, Janne, Blusztajn, Jerzy, Conatser, Christopher S., Konter, Jasper G., Koppers, Anthony A. P., and Kurz, Mark D.
Abstract:: Lau Basin basalts host an array of geochemical signatures that suggest incorporation of enriched mantle source material often associated with intraplate hotspots, but the origin of these signatures remain uncertain. Geochemical signatures associated with mantle material entrained from the nearby Samoan hotspot are present in northwest Lau Basin lavas, and...
