Coastal ocean variability inferred from high resolution models : two case studies

Creator:: Mauch, Matthew L.
Abstract:: In this thesis, high resolution ocean models are used to evaluate and forecast coastal ocean variability in two different applications. In the first study, the 2-km resolution ocean circulation model for the Eastern Bering Sea is utilized to understand whether slope-interior exchange along the path of the Aleutian North Slope...

Understanding the Impact of Global Warming on Orographic Rain Shadows: Insights from a Pseudo-Global Warming Simulation over the Western United States

Creator:: Koszuta, Matthew
Abstract:: Some studies using regional climate models (RCMs) suggest a weakening of the climatological rain-shadow along the Cascade and Sierra Nevada mountains during the western US cool-season. To identify the possible mechanisms of rain-shadow weakening under warming, a new set of 30-year, high-resolution (6 km) pseudo-global warming (PGW) simulations were analyzed...

Hydrogen isotopic composition of C₃₇ alkenones and the ecology and physiology of coccolithophores

Creator:: Wolhowe, Matthew D.
Abstract:: A three-part study was conducted into the impact of physiological and ecological variables on the net isotopic fractionation of hydrogen, α[subscript K₃₇], expressed in C₃₇ alkenones. First, alkenone-producer production, abundance, and export were characterized in the summertime Gulf of California and Eastern Tropical North Pacific using compound-specific, labeled in situ...

Volatile mobility of trace metals in volcanic systems

Creator:: Loewen, Matthew W.
Abstract:: Semi-volatile trace metals like Li, Cu, Mo, Sn, In, and Pb have the potential to track mobility of a volatile phase in volcanic systems. In this dissertation four studies are presented that either directly investigate or are motivated by observations of trace metal behavior in volcanic systems. A common tool...

The 3.1 Ma to 100 ka Goat Rocks Volcanic Complex: Persistence and Evolution of Magmatism at a Long-Lived Major Andesite Locus on the Cascade Arc

Creator:: Wall, Kellie T.
Abstract:: The imposing andesite stratovolcano is the characteristic expression of subduction zone magmatism, posing hazards to coastal populations and bearing insight into deep Earth processes. On a map of a typical volcanic arc, one can easily distinguish the approximately linear alignment and regular spacing of these major edifices that stand out...

Late Holocene Earthquake History Recorded in Alluvial Fan Sequences, Panamint Valley, Eastern California

Creator:: Sethanant, Israporn
Abstract:: The Panamint Valley fault zone (PVFZ) is an active, dextral-oblique normal fault that partially accommodates dextral shear across the Eastern California Shear Zone (ECSZ). The fault system has a complex geometry, characterized by a relatively high-angle dextral oblique normal fault in the south and a low-angle detachment system that accommodates...

Geochronological and Compositional Dataset for the 3.1 Ma to 100 ka Goat Rocks Volcanic Complex

Creator:: Wall, Kellie T.
Abstract:: This dataset is a collection of digital appendices for the PhD dissertation by Kellie T. Wall (2022), entitled "The 3.1 Ma to 100 ka Goat Rocks Volcanic Complex: Persistence and Evolution of Magmatism at a Long-Lived Major Andesite Locus on the Cascade Arc." Each appendix is a file (e.g. Word...

Distribution and abundance of juvenile demersal fishes in relation to summer hypoxia and other environmental variables in coastal Oregon, USA

Creator:: Sobocinski, Kathryn L., Ciannelli, Lorenzo, Wakefield, W. Waldo, Yergey, Matthew E., and Johnson-Colegrove, Angela
Abstract:: The juvenile demersal fish assemblage along the Pacific Northwest coast has received little attention relative to adult life history stages since pioneering work in the 1970s. Increasing severity of hypoxia along the Oregon coast in recent years has prompted investigations into the response of biota in this region. We used...

Evaluating the effectiveness of illuminated and shadowed contour lines

Creator:: Eynard, James D.
Abstract:: Illuminated contour lines, where line width and color are varied based on an angle of illumination, date back to the mid-nineteenth century, but their effectiveness compared to conventional contour lines has not been fully examined. Currently, illuminated contour lines are not widely used in computer-based cartography because they are not...

Ensemble-variational data assimilation for dynamically challenging coastal ocean circulation

Creator:: Pasmans, Ivo
Abstract:: Currently, forecasts produced by the Oregon-Washington (OR-WA) Coastal Ocean Forecast System are constrained by assimilation of only surface observations. The 4-dimensional variational (4DVAR) data assimilation (DA) algorithm is utilized to combine the model and the data, with the time-independent forecast ("background'') error covariance B. In this study, two possible improvements...
