A multiscale climate emulator for long-term morphodynamics (MUSCLE-morpho)

Creator:: Antolínez, José Antonio A., Méndez, Fernando J., Camus, Paula, Vitousek, Sean, González, E. Mauricio, Ruggiero, Peter, and Barnard, Patrick
Abstract:: Interest in understanding long-term coastal morphodynamics has recently increased as climate change impacts become perceptible and accelerated. Multiscale, behavior-oriented and process-based models, or hybrids of the two, are typically applied with deterministic approaches which require considerable computational effort. In order to reduce the computational cost of modeling large spatial and...

Isotopic and Geochemical Signatures of Mantle and Crustal Contributions in Rhyolites from Okataina and Taupo volcanoes, New Zealand

Creator:: Rocco, Nicole D.
Abstract:: Silicic caldera-forming eruptions are some of the largest and most destructive volcanic eruptions known, and present significant local and global hazards. The underlying processes within crustal magma plumbing systems that lead to the accumulation and eruption of large volumes of evolved magma remain enigmatic, yet there is broad consensus that...

Effects of Stage 0 treatment on spring Chinook juveniles within South Fork McKenzie River in Oregon

Creator:: Hahn, Aleah
Abstract:: Low-tech habitat restoration techniques, including Stage 0 treatments, are increasingly applied but often lack robust evaluation of their effects. In 2018, one kilometer of the South Fork McKenzie (SFMK) River, OR was modified to the Stage 0 condition for the benefit of ESA-listed Chinook by raising the incised channel to...

Local and Regional Patterns in Eelgrass (Zostera marina L.) Communities Along an Upwelling-Productivity Gradient in Oregon Estuaries, USA

Creator:: Motley, Jennifer
Abstract:: In this thesis, I investigate the organization of eelgrass (Zostera marina L.) and mesograzer communities across local and regional scales in three upwelling- influenced estuaries located along the Oregon coast, USA. Eelgrass ecosystems are an important source of primary production in estuarine systems, providing numerous ecosystem services, including nursery habitat...

Investigating climate feedbacks across forcing magnitudes and time scales using the radiative kernel technique

Creator:: Jonko, Alexandra
Abstract:: Radiative feedbacks associated with changes in water vapor, temperature, surface albedo and clouds remain a major source of uncertainty in our understanding of climate's response to anthropogenic forcing. In this dissertation climate model data is used to investigate variations in feedbacks that result from changing CO₂ forcing and the time...

GRACE storage-runoff hystereses reveal the dynamics of regional watersheds

Creator:: Sproles, E. A., Leibowitz, S. G., Reager, J. T., Wigington, P. J., Jr., Famiglietti, J. S., and Patil, S. D.
Abstract:: We characterize how regional watersheds function as simple, dynamic systems through a series of hysteresis loops using measurements from NASA's Gravity Recovery and Climate Experiment (GRACE) satellites. These loops illustrate the temporal relationship between runoff and terrestrial water storage in three regional-scale watersheds (> 150 000 km²) of the Columbia...

An Ecological Assessment of a Potential Sea Otter (Enhydra lutris) Reintroduction to the Oregon Coast

Creator:: Kone, Dominique
Abstract:: Sea otters (Enhydra lutris) used to exist along coastlines throughout much of the North Pacific Ocean. During the Maritime Fur Trade, sea otters were extirpated from much of their historic range, including Oregon. There is renewed interest in reintroducing sea otters to Oregon. Managers seek improved understanding of the potential...

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...

Isotopic constraints on the pre-industrial oceanic nitrogen budget

Creator:: Somes, C. J., Oschlies, A., and Schmittner, A.
Abstract:: The size of the bioavailable (i.e., “fixed”) nitrogen inventory in the ocean influences global marine productivity and the biological carbon pump. Despite its importance, the pre-industrial rates for the major source and sink terms of the oceanic fixed nitrogen budget, N₂ fixation and denitrification, respectively, are not well known. These...
