Geologic Face Mapping Methodology Utilizing Global Positioning Systems And Unmanned Aircraft Systems, Luke Whitenburg

Electronic Theses and Dissertations

Geologic field mapping has traditionally been a low-technology process, limited by time in the field and a delicate balance between data collection and coverage area. Advancements in Global Positioning Systems (GPS), Unmanned Aircraft Systems (UAS), and software packages offer new tools and techniques for collecting high volume, accurate geologic information. These tools can provide geologists with safe and efficient ways to collect and process greater volumes of field data.

Field data for this study was collected from three open pit mines using a Trimble Geo 7X GPS unit with Geo 7 Series Rangefinder module and a Phantom 4 Pro V2.0 …

Time And Space Evolution Of Late Permian To Early Triassic Deposits In The Northern Delaware Basin, Southeast New Mexico, U.S.A.: Sediment Sources, Dispersal Pathways, And Timing Of Salt Deformation, Omonde Sitou Akakpo

Electronic Theses and Dissertations

The northern Delaware Basin in southeast New Mexico recorded the deposition of thick evaporite beds followed by siliciclastic materials between the late Permian and Early Triassic. Mineralogy and whole-rock geochemistry of the bioturbated zone and the first mudstone/halite (M1/H1) informal units in the Los Medaños Member (Rustler Formation) suggest felsic volcanic arc origins for the bioturbated zone and felsic upper continental crust passive margin origins for the M1/H1. The previously studied marine transgression that deposited the bioturbated zone likely transported detritus from southern North America and Central American volcanic arcs into the northern Delaware Basin, whereas the regression allowed migration …

Applying Dynamics And Geophysical Methods To Hawaiian Volcanic Terrains And Lava Flows, Brody K. Conner

Electronic Theses and Dissertations

Presented here is the culmination of research spurred by a month-long field expedition to the windward side of the Big Island of Hawai’i during July and August 2023. During this expedition, two ground-penetrating radar units, a Mala GX 160 MHz antenna and a Crossover 1760 dual frequency antenna, were used to survey the basaltic, volcanic landscapes of Mauna Loa and Kīlauea. Post-eruptive digital elevation models of the Ahu’ailā’au (2018 Lower Puna) Eruption and Quantum Geographic Information Systems were used in tandem with GPR Insights software to provide a thorough picture of the surface and subsurface lava flows from Ahu’ailā’au. Using …

Characterization Of Surface Karst Using Lidar And Field Traverses, Fort Hood Military Installation, Coryell County, Texas, Heather Jaclyn Dailey

Electronic Theses and Dissertations

The Fort Hood Military Installation is a karst landscape that has been significantly altered for training exercises that include heavy vehicle maneuvers and simulated combat. Traditional karst surveys are often time-consuming and require extensive field analyses to adequately characterize large areas. Bias is given to areas that are most easily accessible and false negatives are common. Previous studies conducted in the eastern and western portion of the base have understated the abundance and spatial distribution of karst, particularly in the western portion.

This study used field traverses and 0.5-meter Light Detection and Ranging (LiDAR) data to characterize surface karst depressions, …

Comparing Structure From Motion Photogrammetry And Computer Vision For Low-Cost 3d Cave Mapping: Tipton-Haynes Cave, Tennessee, Clinton Elmore

Electronic Theses and Dissertations

Natural caves represent one of the most difficult environments to map with modern 3D technologies. In this study I tested two relatively new methods for 3D mapping in Tipton-Haynes Cave near Johnson City, Tennessee: Structure from Motion Photogrammetry and Computer Vision using Tango, an RGB-D (Red Green Blue and Depth) technology. Many different aspects of these two methods were analyzed with respect to the needs of average cave explorers. Major considerations were cost, time, accuracy, durability, simplicity, lighting setup, and drift. The 3D maps were compared to a conventional cave map drafted with measurements from a modern digital survey instrument …

Delineation Of Karst Potential Using Lidar And Gis Analyses, Fort Hood Military Installation, Texas, Colby Reece

Electronic Theses and Dissertations

ABSTRACT

Traditional karst surveys require extensive field investigations to completely characterize large areas. They are often time-consuming, requiring up to several years to collect and categorize data. Bias is given to areas that are most easily accessible and false negatives are common. The implementation of geographic information systems (GIS) has aided in the aggregation and standardization of karst data; however, these systems have also been used to develop terrain models that allow the user to remotely delineate sinkholes and other surficial features. The Fort Hood Military Installation is a karst landscape that has been altered significantly for use in military …

Dust And Pleistocene Ice Ages: Eolian Sediments And Climate Change At Ziegler Reservoir, Snowmass Village, Colorado, Jeffrey S. Honke

Electronic Theses and Dissertations

The discovery of the Ziegler Reservoir fossil site near Snowmass Village, Colorado presents an opportunity to examine subalpine ecosystem response, during a relatively unknown period, in which climate conditions were similar to present. Finegrained sediments at Ziegler Reservoir represent continuous deposition between ~140–55 ka (thousand years before present), spanning the close of the Bull Lake glacial period [marine isotope stage (MIS) 6], the Sangamon interglacial (MIS 5) and the early stages of the Pinedale (early Wisconsin) glacial period (MIS 4). Ziegler Reservoir is positioned on top of a ridge, at an elevation of 2705 m, and has a small watershed …

Applications Of Gis Analyses And Ecological Approaches To Paleolithic Sites In Portugal., Christopher M. Sims

Electronic Theses and Dissertations

Developments in landscape approaches to archaeological research have been greatly advanced by the use of geospatial technologies. Despite this boon, certain questions remain where the spatial distributions of archaeological material are complicated by other factors. Geomorphic processes significantly hinder site survivability and visibility, and complicate fieldwork. Such is the case for Paleolithic archaeological sites in Portugal, where the current landscape has been drastically altered since Paleolithic human occupation at the Last Glacial Maximum. The challenge to landscape-scale approaches is to provide a bridge between long-term environmental factors and smaller-scale evidence for human-ecosystem interaction. This requires that adaptations be made to …

Impurity And Interdiffusion In The Magnesium-Aluminum System, Sarah Tiffany Brennan

Electronic Theses and Dissertations

Magnesium alloys offer a base of lightweight engineering materials for electronic, military and transportation applications where weight reduction is crucial for higher efficiency. Understanding fundamental diffusion behavior in Mg alloys elicits better materials properties through the optimization of processing techniques and heat treatments, whose material responses are affected by diffusion. The main objective of this study is to provide a clear, comprehensive description of the diffusion behavior in the technically important magnesium-aluminum binary metallic system. In this study, diffusion in the Mg-Al system was observed through solid diffusion couples and thin film specimens in the temperature range of 673-523K. The …

Vitis Seeds (Vitaceae) From The Late Neogene Gray Fossil Site, Northeastern Tennessee, Usa., Fade Gong

Electronic Theses and Dissertations

This study focuses on the morphometric and systematic studies of fossil vitaceous seeds recently recovered from the Gray Fossil Site (7-4.5 Ma, latest Miocene-earliest Pliocene) northeastern Tennessee. Morphologically, all fossil seeds correspond to the extant subgenus Vitis (genus Vitis) of the Vitaceae based on the smooth dorsal surface with a centrally positioned chalaza connected with a conspicuous chalaza-apex groove and short linear ventral infolds that are slightly diverged apically. A multivariate analysis based on 11 measured characters from 76 complete seeds identified three types of seeds, each representing a distinct morphotaxon. Based on comparison with modern and fossil vitaceous …

Man And Nature In Herman Melville's "The Encantadas", Jay J. Jackson

Electronic Theses and Dissertations

It is in light of the fact that no critic has yet seen fit to explore "The Encantadas" with regard to Melville's theme of the man-nature dialectic that this thesis is written. It is the purpose of this paper to show how Melville views man, nature, and their relationship to each other within the bizarre setting of the Galapagos Islands. In no other work save Moby-Dick does Melville so deeply cut to the roots of the question of man and his role in the natural scheme of the cosmos. In order to examine the man-nature tension of "The Encantadas," I …
