Characterizing Yakima Fold and Thrust Belt structures that cross the Cascade Range at the latitude of the Columbia River

Creator:: Gordon, Gabriel
Abstract:: In eastern Washington and western Oregon, southwest-northeast striking thrust faults and folds of the Yakima Fold and Thrust Belt (YFTB) and northwest-striking dextral strike-slip faults accommodate north-south contraction resulting from clockwise rotation of the North American Plate. Though present to the east and west of the Cascade Range, the connectivity...

Using Magnetotellurics Towards Imaging the Primary Magma Reservoir in the Cotopaxi Volcano, Ecuador

Creator:: Angel, Kaitlan W. E.
Abstract:: In this study, 3D finite difference and 2D finite element forward modeling were used to create an electromagnetic sensitivity analysis for the Cotopaxi volcano in Ecuador. Magnetotellurics (MT) is a natural-source electromagnetic geophysical technique that images electrical conductivity. Measuring strong contrasts in electrical conductivity in volcanic materials allows for the...

Subducting Seamounts and Heceta Bank: An Amphibious Seismic Tomography Experiment of the Central Oregon Forearc

Creator:: Nolan, Sarah
Abstract:: Studies reveal differences in slip segmentation and plate coupling along the Cascadia subduction zone. The segment between 44.0°N and 45.0°N exhibited reduced slip in the 1700 megathrust earthquake (Wang et al., 2013) and corresponds with previous rupture boundaries inferred from paleoseismic data (Leonard et al., 2010). Notably, this segment of...

Exploring the Relationship Between 𝛿13Ccarb Signal Preservation and Algorithmic Chemostratigraphic Alignment Accuracy

Creator:: Reynolds, Paige J.
Abstract:: Changes in the stable carbon isotope composition of carbonate rocks (𝛿13Ccarb) are used to establish the relative temporal framework for geological events, such as evolutionary extinction or radiation, between two or more locations. As every local stratigraphic record is intermittent, aligning 𝛿13Ccarb records from two or more locations, a process...

Quantifying dune ecomorphodynamics using UAV-based structure from motion photogrammetry

Creator:: Edgell, Rebecca
Abstract:: Oregon’s foredunes are part of a dynamic coastal environment that constantly evolves in response to both ecological and physical forces. Invasive beachgrasses have outcompeted native dune grass in the region and have influenced the shape of Oregon’s foredunes via species-specific biophysical feedback mechanisms. As climate change induced sea-level rise will...

Measuring sediment transport rates using tracer gravel and RFID technology

Creator:: Lewis, Logan L.
Abstract:: Rates of sediment transport were determined using tracer gravel and a RFID antenna array at Oak Creek (Oregon) to compare a new method with an existing transport relation created from data previously collected in the same study reach. Close to 3,000 tracers were deployed throughout the study reach and were...

A Paleomagnetic and Environmental Magnetic Record from the Eastern South Pacific Sector of the Southern Ocean (0-1.7 Ma): IODP Site U1543

Creator:: Monito, Lindsey
Abstract:: This research presents a u-channel based study of the natural remanent magnetization (NRM), the laboratory magnetization, Anhysteretic Remanent Magnetization (ARM), and magnetic susceptibility (k), from the upper 100 m of International Ocean Discovery Program (IODP) Expedition 383 Site U1543 in the eastern South Pacific sector of the Southern Ocean. Alternating...

Rhyolitic Melt Production in the Midst of a Continental Arc Flare-Up - The Heterogenous Caspana Ignimbrite of the Altiplano-Puna Volcanic Complex of the Central Andes

Creator:: Lewis, Charles T.
Abstract:: The ~5 km3, 4.54 to 4.09 Ma Caspana Ignimbrite of the Altiplano-Puna Volcanic Complex (APVC) of the Central Andes records the eruption of an andesite and two distinct rhyolitic magmas. It provides a unique opportunity to investigate the production of silicic magmas in a continental arc flare-up, where small volumes...

The First Spatiotemporal Estimation of Future Vent Opening at Harrat Khaybar, Saudi Arabia

Creator:: Alohali, Abdullah W.
Abstract:: The 180,000 km² of Arabian lava fields (“harrats” in Arabic) form one of the largest distributed basaltic provinces in the world. Approximately 50% of these are located in Saudi Arabia. The most recent eruption in 1256 AD, as well as seismicity and ground deformation associated with shallow dike emplacement in...

Historical Change and the Hydrogeomorphic Context of Present-day Floodplain Forests in the Willamette Valley, Oregon

Creator:: Bervid, Heather D.
Abstract:: Floodplain forests play many important roles in the fluvial processes and environments of large alluvial rivers, including acting as geomorphological influences and habitat for native fish during high flows. Many large, gravel-bed river systems have undergone substantial change in recent centuries, resulting in loss of forested area to agriculture, reduction...
