Effects of estuary characteristics and tsunami waveforms on transported sand sheets

Creator:: Armstrong, Emma M.
Abstract:: The details of the 1700 Cascadia Subdction Zone earthquake and tsunami can be better constrained using data from tsunami sand sheets, provided knowledge of the waveform, estuary geometry and bed roughness controls on the deposition pattern of the sand sheet. In this study, we use the hydrodynamic and sediment transport...

Role of the Sisters Fault Zone in the Separation of Siletzia from the Cascadia Backarc

Creator:: Mark-Moser, MacKenzie
Abstract:: Oblique subduction of the Juan de Fuca plate beneath the North American plate characterizes the tectonic setting of the Pacific Northwest. North American plate deformation at the latitude of central Oregon consists of the clockwise-rotation of the Siletzia block in the forearc and the extensional Basin and Range province in...

Signatures in the Subsurface - Big & Small Data Approaches for the Spatio-Temporal Analysis of Geologic Properties & Uncertainty Reduction

Creator:: Rose, Kelly Kathleen
Abstract:: Despite more than two centuries of exploration, including more than six million deep wellbores with depths exceeding 40,000 feet in some parts of the world, our ability to constrain subsurface processes and properties remains limited. Characteristics of the subsurface vary and can be analyzed on a variety of spatial scales....

Quaternary Landscape Evolution and the Surface Expression of Plume-Lithosphere Interactions in the Greater Yellowstone Area

Creator:: Guerrero, Eduardo Francisco
Abstract:: Numerous investigations demonstrate that mantle convective processes such as upwelling affect the surface topography of the overriding plate. The surface expression of mantle flow has been coined ‘transient topography’. Transient topography in the North American plate is thought to result from a mantle thermal anomaly beneath the Yellowstone volcanic center,...

Debris flows in glaciated catchments : a case study on Mount Rainier, Washington

Creator:: Legg, Nicholas T.
Abstract:: Debris flows, which occur in mountain settings worldwide, have been particularly damaging in the glaciated basins flanking the stratovolcanoes in the Cascade Range of the northwestern United States. This thesis contains two manuscripts that respectively investigate the (1) initiation processes of debris flows in these glaciated catchments, and (2) debris...

Citizen Science Research : A Focus on Historical Whaling Data and a Current Marine Mammal Citizen Science Project, Whale mAPP

Creator:: Hann, Courtney
Abstract:: Citizen science work has built the foundation of much of our knowledge on regional-scale large cetacean spatial patterns through historical whaling data. Historical whaling data on sperm whales was used as an example to show the type of ecological questions large-scale, long-term citizen science datasets can address. Results from the...

Spatio-Temporal Patterns of Tree Establishment in the M1 Meadow of the H.J. Andrews Experimental Forest

Creator:: Jones, Katherine E.
Abstract:: Montane meadows in the Cascade Range of Oregon have been declining due to tree establishment since records began. Montane meadow complexes in the H.J. Andrews Experimental Forest shrank by 60 to 75% from 1949 to 2005, but fine scale temporal and spatial processes of tree establishment in these meadows are...

Up-estuary extent and lithologic characteristics of tsunami deposits attributed to the 1700 Cascadia earthquake within Alsea Bay, OR

Creator:: Spruell, John T.
Abstract:: Cascadia’s 1700 earthquake generated a tsunami and widespread subsidence along Pacific Northwest coastline. The tsunami deposited sandy sediments in many Oregon coastal estuaries, such as Alsea Bay. Although the recurrence of subduction-generated megathrust earthquakes and tsunami events in this region are recorded in the stratigraphy, knowledge of the full inland...

Illuminating Patterns in Dark Microbial Matter: Diversity and Distribution of Fungi and Actinobacteria in Deep-sea Methane Seep Sediments

Creator:: Ardor Bellucci, Lila
Abstract:: Fungi and Actinobacteria are essential actors in global biogeochemical cycles of carbon and nutrients, and have both been recently appreciated for their roles in marine ecosystems. However, the diversity and distribution of these ubiquitous, but low-abundance microbes in deep-sea habitats remains poorly understood, particularly in chemosynthetic habitats such as methane...

On the Manifestation of Deformation and Evolution of Two Cenozoic Orogens

Creator:: Lamont, Ellen A.
Abstract:: The word orogenesis is derived from the Greek words oros meaning mountains and genesis meaning creation and refers to the study of the complex processes involved in the growth and evolution of mountain ranges (orogens). Orogens develop where crustal deformation builds topography and forms landscapes. This dissertation explores the role...
