Magnetotelluric Constraints on Lithospheric Properties in the Southeastern United States

Creator:: Murphy, Benjamin S.
Abstract:: By inverting EarthScope long-period magnetotelluric (MT) data from the southeastern United States (SEUS), we obtain electrical conductivity images that provides key insights into the geodynamics of this region. Significantly, we resolve a highly electrically resistive block that extends to mantle depths beneath the modern Piedmont and Coastal Plain physiographic provinces....

Interactions of wind-driven and tidally-driven circulation in the Oregon coastal ocean

Creator:: Osborne, John J.
Abstract:: Influences of tidal and slower (subtidal) oceanic flows over the continental shelf and slope off Oregon are studied using a high-resolution ocean circulation model and comparative model-data analyses. The model is based on the Regional Ocean Modeling System (ROMS), a fully nonlinear, three-dimensional model (using hydrostatic and Boussinesq approximations). The...

Ecological Consequences of Marine Debris: Understanding Large-Scale Species Transport on Tsunami Debris and Research Priorities in Oregon

Creator:: Gillman, Reva A.
Abstract:: The release of marine debris into the oceans and seas is a global issue of growing concern. These materials are harmful to marine environments and can also transport non-native species to novel habitats. Non-native species floating on marine litter is one of the lesser known impacts associated with marine debris....

Remineralization of marine particulate organic matter

Creator:: Burkhardt, Brian Gary
Abstract:: Marine microorganisms play a significant role in the cycling of nutrients in the open ocean through production, consumption, and degradation of organic matter (OM). Carbon (C), nitrogen (N), and phosphorus (P) are essential ingredients in every known recipe for life. However, the cycling of each of these elements proceeds at...

Investigation of Deep Seismic Reflections Beneath the Forearc in the South Central Chile Subduction Zone

Creator:: Zhang, Edward
Abstract:: The south central Chilean margin is one of the most seismically active subduction zones on Earth, generating some of the largest earthquakes on the planet, including the largest ever recorded in 1960 near Valdivia, Chile (Mw 9.5). Using the 15 km streamer and 6600 in3 tuned seismic airgun array aboard...

The Data Stream: Assessing the Flow of Real Time Marine Science Data from Research Vessel to the Classroom

Creator:: Miller, Danielle N.
Abstract:: Today’s technology-based society makes information more accessible than ever, in turn creating a growing demand for a workforce that has the skills necessary to utilize data. Contributing to this influx of data is Oregon State University (OSU), who was selected to guide the design and construction process of three Regional...

Magnetotelluric Studies of Tectonic Systems and Volcanic Areas of North America

Creator:: Bowles-Martinez, Esteban
Abstract:: Magnetotellurics is used in two geologic settings on scales ranging from 1000-km tectonic structures to local features hundreds of meters wide. These areas are the Midcontinent Rift System (MRS) and its related mantle plume in the northern Midwestern United States and Newberry Volcano in central Oregon. The MRS study uses...

Source Parametrization of Earthquakes along Juan de Fuca Transform Boundaries

Creator:: Sapkota, Birat
Abstract:: The Juan de Fuca plate system is what remains of Farallon plate subducting under the continental North American plate. Blanco Transform Fault Zone (BTFZ) consists of a network of strike-slip faults discontinued by pull apart depressions which o↵sets the Juan de Fuca Ridge and the Gorda Ridge. Detailed analysis of...

Earthquake Relocation in Three-Dimensional Velocity Models for Central Cascadia Continental Margin

Creator:: Ghorbani, Paria
Abstract:: We used data from Cascadia Initiative and Blanco Transform Fault Zone array of ocean bottom seismometers and hydrophone to look at the seismicity and specially depth of the Central Cascadia Continental Margin events. Events were detected and located automatically with Antelope software package (Boulder Real Time Technologies). We looked at...
