Hidden Intrabasin Extension: Evidence For Dike-Fault Interaction From Magnetic, Gravity, And Seismic Reflection Data In Surprise Valley, Northeastern California, Noah D. Athens, Jonathan M.G. Glen, Simon L. Klemperer, Anne E. Egger, Valentina C. Fontiveros

All Faculty Scholarship for the College of the Sciences

The relative contributions of tectonic and magmatic processes to continental rifting are highly variable. Magnetic, gravity, and seismic reflection data from Surprise Valley, California, in the northwest Basin and Range, reveal an intrabasin, fault-controlled, ~10-m-thick dike at a depth of ~150 m, providing an excellent example of the interplay between faulting and dike intrusion. The dike, likely a composite structure representing multiple successive intrusions, is inferred from modeling a positive magnetic anomaly that extends ~35 km and parallels the basin-bounding Surprise Valley normal fault on the west side of the valley. A two-dimensional high-resolution seismic reflection profile acquired across the …

Hornbrook Formation, Oregon And California: A Sedimentary Record Of The Late Cretaceous Sierran Magmatic Flare-Up Event, Kathleen D. Surpless

Geosciences Faculty Research

Early Late Cretaceous time was characterized by a major magmatic flare-up event in the Sierra Nevada batholith and early phases of magmatism in the Idaho batholith, but the sedimentary record of this voluminous magmatism in the U.S. Cordillera is considerably less conspicuous. New detrital zircon U-Pb ages from the Hornbrook Formation in southern Oregon and northern California reveal a significant and sustained influx of 100–85 Ma detrital zircons into the broader Hornbrook region beginning ca. 90 Ma. Detrital zircon ages and hafnium isotopic compositions, combined with whole-rock geochemistry, suggest that sediment was largely derived from the Sierra Nevada, requiring uplift …

From A Public Health Perspective: Fracking And Other Unconventional Oil And Gas Extraction Techniques In California, Hilda J. Cerros

Master's Projects and Capstones

California strives to be a leader in clean energy, yet it the third largest producer of oil and gas. To tackle the need for a cleaner environment, free of toxic chemicals, the Center for Environmental Health (CEH) establish a Healthy Energy Choice campaign. CEH and the Healthy Energy Choice Program collaborate with other organizations and communities to shine light on the public health impacts associated with fracking and other oil and gas extraction methods. The following paper is a summary of a 300- hour field work experience completed at the CEH’s Healthy Energy Choice Program specifically with an analyzes of …

Innovations in Managing Western Water: New Approaches for Balancing Environmental, Social and Economic Outcomes (Martz Summer Conference, June 11-12)

Many aspects of western water allocation and management are the product of independent and uncoordinated actions, several occurring a century or more ago. However, in this modern era of water scarcity, it is increasingly acknowledged that more coordinated and deliberate decision-making is necessary for effectively balancing environmental, social, and economic objectives. In recent years, a variety of forums, processes, and tools have emerged to better manage the connections between regions, sectors, and publics linked by shared water systems. In this event, we explore the cutting edge efforts, the latest points of contention, and the opportunities for further progress.

Antibacterial Activity Of Native California Medicinal Plant Extracts Isolated From Rhamnus Californica And Umbellularia Californica., Maria G. Carranza, Mary B. Sevigny, Debashree Banerjee, Lacie Fox-Cubley

Natural Sciences and Mathematics | Faculty Scholarship

BACKGROUND: Antimicrobial resistance (AMR) is a major threat to global public health. Medicinal plants have long been used as remedies for infectious diseases by native cultures around the world and have the potential for providing effective treatments for antibiotic-resistant infections. Rhamnus californica (Rhamnaceae) and Umbellularia californica (Lauraceae) are two indigenous California plant species historically used by Native Americans to treat skin, respiratory and gastrointestinal infections. This study aimed to assess the in vitro antimicrobial activity of methanolic extracts of leaves and bark of R. and U. californica against methicillin-resistant Staphylococcus aureus (MRSA) and other Gram-positive and Gram-negative bacteria.

METHODS: Methanolic …

Life Cycle Assessment Of Reclaimed Water For Potable And Nonpotable Reuse In California, Antonia Estevez-Olea

Master's Projects and Capstones

Extreme drought, water scarcity and population growth is forcing California to seek out new water sources. Reclaimed water is considered one of the best alternatives to alleviate water shortages and help meet the water demand sustainably. However, the environmental impacts of reclaimed water have not been fully studied to ensure that the overall benefits of reclaimed water do indeed outweigh the environmental, social, and economic costs. In this study a life cycle assessment (LCA) for potable (direct and indirect) and nonpotable reuse will be conducted to identify and quantify major environmental, social, and economic problems that are attributed to reclaimed …

Aerosol Size Distribution Measurements During The 2014 Nasa Sarp Campaign In The Central Valley And Sierra Nevada Mountains In California, Victoria A. Hampton

Mahurin Honors College Capstone Experience/Thesis Projects

Aerosols are directly and indirectly related to global climate by scattering radiation and also by seeding cloud formation. As a part of the 2014 NASA Student Airborne Research Program (SARP), research flights were conducted over the Central California region to better understand air quality in large urban California cities and also in the Central Valley. Using a Droplet Measurement Technologies Ultra High Sensitivity Aerosol Spectrometer (DMT-UHSAS), aerosol size distributions were measured across geographic regions of interest. Previous research has suggested that aerosols originating in the Central Valley may travel eastward to the Sierra Nevada and, once lifted orographically, could suppress …

Correlations Of Fault Rock Constitutive Properties Derived From Laboratory Retrieved Data Of The North-Eastern Block Of The Southern San Andreas Fault, Mecca Hills, Ca Via Computational Analysis., Ryan M. Lee

Physics Capstone Projects

We aim to characterize fault-structure-related rocks via correlation between the various geophysical characteristics of samples retrieved from the southern San Andreas Fault (SSAF) near the Mecca Hills region in Southern California. Samples from this area were retrieved from the San Andreas Fault Observatory at Depth (SAFOD) near Parkfield, California at a depth of approximately 3km. Core samples of various lithologies were gathered from the borehole and analyzed using various geophysical methods. Emphasis was placed in possible correlations and relationships between varying lithologies and calculated values of unconfined compressional strength (UCS) and cohesion. Using retrieved data from the samples, as well …

A Fishery, A Sanctuary, A Sink, And A Disaster: The Often Hapless Management Of California's Salton Sea, William M. Mclaren

Will McLaren

Over a century ago, a series of questionable management decisions and water-diversion engineering mistakes in Southern California produced an “unnatural” waterbody called the Salton Sea. Since then, the Sea has served as a recreational destination with fluctuating popularity, a sanctuary for migratory birds, a sink for agricultural runoff and urban wastewater, and one of the most productive tilapia and corvina fisheries in the United States. However, the Sea’s resources and associated uses have steadily deteriorated since its formation.

The contrast between the ethics that drove resource management decisions at the time of the Salton Sea’s formation to those employed in …
