Carbon storage in U.S. Pacific Northwest coastal dunes : the role of invasive beachgrasses and sand supply

Creator:: Stepanek, John
Abstract:: As global atmospheric carbon emissions continue to rise, scientists and land managers are increasingly looking to natural ecosystems to sequester and store carbon to buffer the impacts of climate change. Despite their small geographic size, many coastal ecosystems such as salt marshes, seagrass meadows, and mangroves sequester large amounts of...

Nearshore wave predictions along the Oregon and southwest Washington coast

Creator:: García-Medina, Gabriel
Abstract:: This thesis contains a manuscript describing the implementation of a high resolution wave forecasting model for the coasts of Washington and Oregon. The purpose of this project was to advance the wave predictive capabilities of the states of Oregon and the southwest part of Washington by including the effects of...

Data Assimilation using Synthetic-Aperture Radar Imagery for Bathymetry Inversion at the Mouth of the Columbia River

Creator:: Harper, Spencer H.
Abstract:: Synthetic-aperture radar (SAR) imagery can provide wavenumber and frequency data to generate bathymetry estimates for locations where limited access or extreme ocean conditions can make standard bathymetry survey techniques difficult or impossible. The availability of SAR data could allow for regular bathymetry estimates of navigational channels providing insight into dredging...

Exploring the Impacts of Climate and Management on Coastal Community Vulnerability through Alternative Future Scenarios

Creator:: Mills, Alexis K.
Abstract:: Coastal communities throughout the U.S. Pacific Northwest face heightened risk due to sea level rise and increasing storminess resulting in coastal flooding and erosion hazards. Incorporating uncertainty with respect to both climate change and policy decisions is essential to project the evolving probability of coastal inundation and erosion, and the...

Stratigraphic correlation of seismoturbidites and the integration of sediment cores with 3.5 kHz chirp subbottom data in southern Cascadia

Creator:: Black, Bran
Abstract:: In order to evaluate the shallow stratigraphy along the southern Cascadia abyssal margin and northern California abyssal plain, CHIRP subbottom profiles capable of imaging individual turbidite beds in the upper tens of meters of the subsurface were collected. Reflectors imaged with the 3.5 kHz CHIRP subbottom data represent turbidite beds...

Influence of macro-roughness on tsunami runup & forces

Creator:: Bridges, Kerri-Jane
Abstract:: This thesis is comprised of a manuscript based on a laboratory experiment run in the Tsunami Wave Basin as part of a research project funded by the Network for Earthquake Engineering Simulation called Housesmash. The purpose of the experiment was to better understand the role of the urban environment, represented...

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...

Assessing the Risk and Resilience of Coastal Communities: An Application to the Joint Seismic-Tsunami Hazard at Seaside, Oregon

Creator:: Sanderson, Dylan, R.
Abstract:: This thesis presents two conceptually linked papers outlining methodologies to improve community resilience. Both papers employ Seaside, Oregon as a testbed community and consider the seismic-tsunami hazard posed by the Cascadia Subduction Zone. The first paper presents a framework to deaggregate the results of a multi-hazard, multi-infrastructure, damage analysis by...

Evaluating Coastal Protection Services Associated with Restoration Management of an Endangered Shorebird in Oregon, U.S.A.

Creator:: Carroll, Lindsay J.
Abstract:: Coastal sand dunes and beaches offer a variety of ecosystem services such as coastal protection, sand stabilization, species conservation, and recreation. However, the management and balance of ecosystem services offered by dunes and beaches is challenging when ecosystem services interact across the landscape. Management focusing only on one ecosystem service...

On the nearshore impact of wave energy converter arrays

Creator:: O'Dea, Annika Magnuson
Abstract:: Radiation stresses, defined as the excess flow of momentum due to the presence of waves (Longuet-Higgins, 1964), are the main drivers behind the cross-shore and longshore forcing that results in wave setup, set-down, and longshore currents (e.g. Svendsen, 2006). Longshore currents entrain and transport sediment and therefore play an important...
