Evidence Of Tectonic Uplift Along The Oceanic Fault Near San Simeon, San Luis Obispo County, California, George Gecy
Earth and Soil Sciences
Post-Seismic satellite imagery after the 2003 earthquake near San Simeon confirmed 10s of millimeters of north-east side uplift along the Oceanic Fault. In order to determine whether or not there has been a history of tectonic uplift northeast of the Oceanic Fault zone, longitudinal profiles of Morro Creek and San Simeon were made using a digital planimeter and 1:24,000 scale maps. Utilizing the stream profiles, convexities could be observed in the streams coinciding where the streams crossed the Oceanic Fault; of the stream profiles, the convexity along San Simeon Creek could be confirmed to be caused by north-east side uplift …

The Influence Of Vegetation And Landscape Position On Soil Temperature Change In A Sagebrush-Steppe Eastern Sierra Environment: Implications On Soil Taxonomy, Nathan Michael Lurie
The Influence Of Vegetation And Landscape Position On Soil Temperature Change In A Sagebrush-Steppe Eastern Sierra Environment: Implications On Soil Taxonomy, Nathan Michael Lurie
Earth and Soil Sciences
Soil temperature is a parameter that has been studied for a considerable time and from many different perspectives. However, relatively few studies have been conducted for taxonomic purposes and fewer still have focused on how changes in soil temperature related to global climate change may affect soil taxonomy. Soil temperature regimes are used to subdivide soils with similar properties that exist in dissimilar climate zones requiring different management practices depending on intended use. Seven sites with variable surficial features were used for this study within a cohesive sagebrush-steppe Eastern Sierra glacial moraine landform. Soil temperature was measured once a month …

Urban Heat Island Expansion In The Greater Las Vegas Metropolitan Area, Alex Remar
Earth and Soil Sciences
The growth of human settlements into vast urban metropolitan areas is often accompanied by relatively higher temperatures in comparison with surrounding rural countrysides, a phenomenon known as the “urban heat island effect.” The city of Las Vegas has been selected as an examination of this trend because of its unprecedented urban growth in the last 50 years, which has been mapped by satellite imagery for several decades. Studying the growth of Las Vegas’ relatively new heat island can provide valuable insight into the causes and magnitude of all urban heat islands in general.
In this investigation, a series of temperature …

Detrital Zircon Geochronology For Neoproterozoic To Cambrian Sediment Sources Of The Deep Creek Range And The Pilot Range In The Southwestern United States, Kaysea Perry
Earth and Soil Sciences
Detrital zircon studies of miogeoclinal sediments can help provide a deeper look into the mechanisms leading to continental breakup by studying the evolution of the continental margin of North America. Few detrital zircon studies have been conducted to support previous research and theories about the sedimentation of the Miogeocline from the Neoproterozoic to the Cambrian. Studies targeted at the Basin and Range province of the western United States show a trend of increasing local sediment sources. We analyzed detrital zircons from the Pilot and Deep Creek Ranges in Nevada and Utah via LA-MC-ICP-MS at the University of Arizona LaserChron Center …
Social Behaviors Of Modern And Indigenous Peoples Impacting The Ecology Of The Amazon Rain Forest In Brazil, Josef W. Schaffer
Social Behaviors Of Modern And Indigenous Peoples Impacting The Ecology Of The Amazon Rain Forest In Brazil, Josef W. Schaffer
Earth and Soil Sciences
Human induced disruption of the environment is prevalent in every culture. In Brazil, the effects of massive deforestation have become apparent since the nineteen eighties. However, along with deforestation, and a coinciding loss in an economic resource for the country, is a significant loss of natural habitat and species extinction. The Amazon in Brazil contains a large proportion of the world’s species diversity that is threatened by the socio-economic activities of modern Brazilian culture. Historically and presently, indigenous groups have contributed to insignificant levels of ecological disruption and are themselves threatened by the activities of modern Brazilians. The effects of …

Quaternary Deposits Near The San Emigdio Mountains, California: Evidence For A Paleolandscape?, Paul G. Lavelle
Quaternary Deposits Near The San Emigdio Mountains, California: Evidence For A Paleolandscape?, Paul G. Lavelle
Earth and Soil Sciences
Discontinuous low-relief surfaces are scattered throughout relatively high topography within the San Emigdio Mountains, California. These surfaces are considered anomalous, as they are preserved in a dissected, mountainous region that is affected by ongoing orogeny. Previous research has suggested that the low-relief surfaces may represent a once-contiguous alluvial surface. This project utilizes field mapping and sedimentological analysis to determine if the surfaces represent a paleo landscape. What is apparent from field work is the presence of two morphologically distinct lithologic units that most likely represent surficial geologic components of the same relict landscape.
