Characterizing Basement Structures To Evaluate Their Influence On Overlaying Sedimentary Layers: Case Study Of Three Fields In The Central Kansas Uplift, Muhammad S. Karim
Characterizing Basement Structures To Evaluate Their Influence On Overlaying Sedimentary Layers: Case Study Of Three Fields In The Central Kansas Uplift, Muhammad S. Karim
Master's Theses
Potential field and well log data were used to investigate basement features and the overlaying sedimentary layers across four counties in the Central Kansas Uplift. The objective of this study was to (1) investigate and determine the orientation of basement structures/features, (2) estimate the depth to basement, and (3) examine the influence (if any) and relationship between the basement features and the overlaying sedimentary deposits of three oil fields in the study area. Aeromagnetic data was used to interpret and map basement features by applying derivative filters. Well log data was used to pick formation top values and create contour …
The Utility Of Foraminifera In Documenting Sediment Provenance For Overwash Deposits: A Case Study Using Sediments Deposited By Tropical Cyclone Pam In Vanuatu, Thomas Kosciuch
Master's Theses
Tropical cyclone inundation is a major threat to the highly exposed islands of the South Pacific. This vulnerability was highlighted in March 2015 when Tropical Cyclone (TC) Pam made landfall on Vanuatu as a Category 5 storm, impacting coastlines with storm surges that produced high water marks up to 7 m above MSL and deposited sediments up to 400 m inland. We examined the foraminiferal assemblages contained within TC Pam sediments at two locations in Vanuatu: a mixed-carbonate embayment (Manuro), and a volcaniclastic beach (Port Resolution Bay; PRB). At Manuro, the TC Pam sediments were up to 10 cm thick …
The Impact Of Fe-Ti Oxide Concentration On The Structural Ridgity Of The Lower Oceanic Crust, Atlantis Bank, Southwest Indian Ridge, Daniel Winkler
The Impact Of Fe-Ti Oxide Concentration On The Structural Ridgity Of The Lower Oceanic Crust, Atlantis Bank, Southwest Indian Ridge, Daniel Winkler
Master's Theses
Fe-Ti oxides are important components of oceanic core complexes (OCC) formed at slow-spreading mid-ocean ridges since Fe-Ti oxides are more susceptible to crystal-plastic deformation than silicate minerals. This study investigated the predicted relationship between the presence and concentration of Fe-Ti oxides and the presence and intensity of crystal-plastic deformation in gabbroic samples from Atlantis Bank, Southwest Indian Ridge (SWIR). Atlantis Bank is an oceanic core complex that formed through the exhumation of lower oceanic crust along a detachment fault. OCCs form along slow-spreading ridges and are characterized by the complex interactions between magmatism and lithospheric extension, thus making these complexes …
Sedimentary Characteristics And Nutrient Sequestration Of Embanked Floodplains Along The Lower Mississippi River, Mississippi And Louisiana, R M Malitha Rathnayake
Sedimentary Characteristics And Nutrient Sequestration Of Embanked Floodplains Along The Lower Mississippi River, Mississippi And Louisiana, R M Malitha Rathnayake
Master's Theses
The Mississippi River Basin is the largest river basin in North America and the third largest river basin in the world. Most of the corn, soybeans, wheat, cattle, and hogs harvested in the United States come from the Mississippi River Basin and about 58% of the entire drainage basin is croplands. Runoff from these lands carries sediments and nutrients, and the Mississippi River transports these downstream and ultimately deposits them in the Gulf of Mexico. The northern Gulf of Mexico is one of largest human-caused hypoxic zones in the world. Hypoxia is the phenomena where the dissolved oxygen level decreases …
Morphometric Changes In Semicircular Canal Shape Within Theropoda (Dinosauria: Saurischia) And Their Dietary Implications, James Logan King
Morphometric Changes In Semicircular Canal Shape Within Theropoda (Dinosauria: Saurischia) And Their Dietary Implications, James Logan King
Master's Theses
heropods were a suborder of dinosaurs that displayed a large variety of dietary preferences throughout the Mesozoic and into the Cenozoic as modern birds. Being ancestrally carnivorous, many of the large-bodied early theropods were hypercarnivorous; however, members of Theropoda diversified their diets into omnivory and herbivory. Modern vertebrates with different dietary preferences have different spatial sensitivities to changes in head and body movement. In order to test if theropod diet plays a major role in the rostral (RSC), caudal (CSC), and lateral (LSC) semicircular canal shape, therizinosaurs, tyrannosaurids, ratites, an allosaurid, an ornithomimid, and a phorusrhacid were analyzed via 2D …
Analysis Of Big Creek Aquifer Alluvial Facies And Associated Phreatic Surface Contour Maps Hays, Ellis County, Kansas, Krisopher John Neuhauser
Analysis Of Big Creek Aquifer Alluvial Facies And Associated Phreatic Surface Contour Maps Hays, Ellis County, Kansas, Krisopher John Neuhauser
Master's Theses
Three contour maps of groundwater elevation levels below Hays, Kansas generated in 2016 show that the phreatic surface in eight monitoring wells declined 3.6 inches to 1 foot 9.6 inches over a three-month period of July, August, and September. They also indicate that groundwater flows in curvilinear directions toward Big Creek. Analyses of ten north-south oriented structural cross sections of the alluvial fill beneath the central region of Hays provide evidence of buried low-sinuosity and meandering streams, floodplains, and possibly adjoining tributaries and abandoned channels. Correlation of the more porous and permeable sand and gravel facies along a northwest to …
Hydrogeological Study Of A Municipal Groundwater Well Field In Central Kansas, Tyler Saryerwinnie
Hydrogeological Study Of A Municipal Groundwater Well Field In Central Kansas, Tyler Saryerwinnie
Master's Theses
The City of Victoria is a small town of approximately 1,200 people situated in Central Kansas. Along with other communities in Kansas, recent drought has made the issue of water quality and availability a pressing concern with local officials. This city relies heavily on the use of ground-water wells located south of the town near the Big Creek channel. It is the purpose of this study to define the hydrogeological conditions effecting the City’s well field, and in turn apply this information to define an area of influence and outline potential hazards for the well field. Utilizing previous studies, along …
The Relationship Among Suture Complexity, Shell Form, And Stratigraphic Formation In Ammonites Of The Western Interior Seaway, Darrah Jorgensen
The Relationship Among Suture Complexity, Shell Form, And Stratigraphic Formation In Ammonites Of The Western Interior Seaway, Darrah Jorgensen
Master's Theses
Throughout ammonite evolution, shell suture patterns grew increasingly more complex, but the purpose of these sutures has long been debated. One hypothesis is that suture complexity is related to the structural integrity of the shell under pressure. To test this hypothesis, suture complexity was compared to shell form and stratigraphic formation to determine if there were significant differences in suture complexity, as a proxy for structural integrity, among shell forms or stratigraphic formations. Highly complex sutures might have allowed for the tightly coiled form of many ammonites, an advantage compared to less coiled forms because the pressure is distributed over …
Uas-Collected Multispectral Imagery For The Identification Of Rangeland Vegetation In A Southern Mixed-Grass Prairie, Adam Rusk
Master's Theses
The interest in using unmanned aerial systems (UAS) for remote sensing of natural resources and ecology has grown rapidly in recent years and continues to develop. Recent improvements in the cost, size, and accessibility of consumer-grade UASs are now facilitating image collection on low-flying UAS platforms. Rangelands provide a unique opportunity to explore the uses of UAS remote sensing due to their large spatial extent and spatial and temporal heterogeneity. This study focuses on the use of UAS’s to identify rangeland vegetation in a southern mixed-grass prairie in Kansas. Two primary questions were asked: 1) Do small UASs with low-cost …
Stable Isotope Diet Analysis Of Teleoceras Fossiger From The High Plains Of Kansas, Patrick J. Wilson
Stable Isotope Diet Analysis Of Teleoceras Fossiger From The High Plains Of Kansas, Patrick J. Wilson
Master's Theses
Stable isotope geochemistry provides a way of examining both modern and ancient ecosystems. One important use of stable carbon isotopes is to determine the amount of C3 versus C4 plant biomass in the diet of herbivorous mammals. C3 plants have a more negative stable carbon isotope ratio (δ13C) than C4 plants because of the different photosynthetic pathways each type uses. These different δ13C values are preserved in the hydroxyapatite of herbivores upon consumption of the different plant types. The purpose of this study it to use δ13C values from serial samples of tooth enamel from six isolated permanent molars of …
