Global Economic Impacts Of Shoreline Degradation: A Socioeconomic Analysis, Alexa Brockamp Jun 2014

Global Economic Impacts Of Shoreline Degradation: A Socioeconomic Analysis, Alexa Brockamp

Global Honors Theses

Shoreline Degradation is an economically important issue, which damages coastal tourism economies, and causes shifts in flows of tourist capital. Shifts in flows of tourist capital have the potential to cause shifts in economic power relationships between nations. Governments and planning agencies should acknowledge the inherent dependence of coastal tourism economies on shoreline health and water quality, and conceptions framing the two issues as dichotomous are destructive – causing urban decisions to be made as if environmental and economic interests are mutually exclusive. It is important that such perceptions shift in order to maintain healthy coastal economies. Additionally, the socio- …

Detrital Zircon Geochemistry Of The Nacimiento Block, Santa Ynez Mountains, California, Vincent Zhao Jun 2014

Detrital Zircon Geochemistry Of The Nacimiento Block, Santa Ynez Mountains, California, Vincent Zhao

Natural Resources Management and Environmental Sciences

The long-lived California section of the North American Cordillera is one of the most studied continental margins in the world; however, erosion and deformation in areas along the San Andreas Fault and the Sur-Nacimiento Fault has erased sections of the Cordillera which could provide insight in Cordilleran processes. The lost sections are partially preserved in detrital zircons deposited alongside the arc in fore-arc basins such as in the Toro Formation of the Nacimiento block which represents the coastal central California equivalent to the Great Valley Group, located in the Santa Ynez Mountains. Geochemical analysis of the detrital zircons from the …

California Drought: A Need For Agricultural Revolution In The Golden State, Benjamin Clinkinbeard May 2014

California Drought: A Need For Agricultural Revolution In The Golden State, Benjamin Clinkinbeard

2014 Student Theses

California is in a drought State of Emergency, which is fueling negative social and economic consequences. After multiple years of below average rainfall, California has arrived at one of the most severe droughts in recorded history. Climate change is upon the Golden State, and the ugly consequences need to encourage citizens to spur green movements combating environmental destruction. The agriculture industry is in need of drastic change in order to secure a future that includes clean water, and fresh food for a growing population. Currently, the agricultural techniques practiced are far from sustainable. Adopting a new ideal on what it …

Evaluation Of The Development And Effectiveness Of Copper Total Maximum Daily Loads (Tmdls) To Achieve Marine Water Quality Criteria, Joanna Florer May 2014

Evaluation Of The Development And Effectiveness Of Copper Total Maximum Daily Loads (Tmdls) To Achieve Marine Water Quality Criteria, Joanna Florer

Master's Projects and Capstones

Elevated concentrations of certain chemicals in surface water are known to be toxic to aquatic organisms (e.g., barnacles, algae, and fish). For a number of these chemicals (e.g., tributyltin [TBT], copper) federal and state water quality standards exist to protect aquatic organisms. As a means to comply with water quality standards, regulatory agencies establish Total Maximum Daily Loads (TMDLs) to reduce concentrations of toxic chemicals from entering waterways. A TMDL determines the maximum amount of pollutant loading a water body can sustain and still achieve water quality standards; they are developed to ensure that surface water concentrations meet applicable criteria. …

Fault And Fluid Interactions In The Elsinore Fault-West Salton Detachment Fault Damage Zones, Agua Caliente County Park, California, Rebekah Erin Wood May 2014

Fault And Fluid Interactions In The Elsinore Fault-West Salton Detachment Fault Damage Zones, Agua Caliente County Park, California, Rebekah Erin Wood

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study area provides a unique opportunity to study the intersection of the Elsinore and West Salton detachment faults in southern California, effusing warm springs, and alteration products in the midst of the fault intersection. Structural mapping and compiling previous maps supply an interpretation of the fault zone geometries within the Tierra Blanca Mountains. Geochemical analysis of the crystalline basement and altered protolith help determine the effects of faulting and fluid flow in the study area. In the Tierra Blanca Mountains, the Elsinore strike-slip fault system transitions from the double-stranded Julian segment and Earthquake Valley fault in the northwest, to …

Eclogites And Eclogites: Oxygen Isotope Evidence Of A Shared Subduction Origin For Franciscan Eclogites And Moses Rock Eclogite Xenoliths, William F. Hoover Jan 2014

Eclogites And Eclogites: Oxygen Isotope Evidence Of A Shared Subduction Origin For Franciscan Eclogites And Moses Rock Eclogite Xenoliths, William F. Hoover

Honors Papers

Eclogites can be found in two distinct tectonic settings in the western USA: in the Franciscan Complex as tectonic blocks in a fossil accretionary wedge, and in the Navajo Volcanic Field as xenoliths in diatremes. Intra-crystal oxygen isotope analyses of garnets from these two settings provide important information on the source, composition and timing of fluid interactions in both eclogite settings. Because of the well-documented relationship between Franciscan subduction and the volcanism in the Navajo Volcanic Field, the samples in this study can be directly compared to determine if they share a common origin. The Navajo eclogites in this study …

Controls On Fault Geometry During Early Stages Of Extension In The Larkspur Hills, Northwest Basin And Range, Diana Jean Strickley Jan 2014

Controls On Fault Geometry During Early Stages Of Extension In The Larkspur Hills, Northwest Basin And Range, Diana Jean Strickley

All Master's Theses

Detailed analyses of normal faults in the Larkspur Hills, CA-NV, northwest Basin and Range, offer insight into factors controlling normal fault initiation, growth, and distribution. N-trending faults in the southern portion of the study area share trends of major range-bounding structures and Pliocene linear volcanic vents; in contrast, NNW- and NNE- trending faults dominate further north and into south-central Oregon. Stress analyses and comparison with experimental and field data suggest that preexisting structures control faults in the northern Larkspur Hills, while faults form perpendicular to σ3 in the southern hills. The change in fault orientations is abrupt, occurring across a …
