Sedimentology Of A Small Estuarine Marsh Along East (Pensacola) Bay, Florida, Jesse Pfadenhauer
Sedimentology Of A Small Estuarine Marsh Along East (Pensacola) Bay, Florida, Jesse Pfadenhauer
Honors Theses
Sediment samples from a marsh along East (Pensacola) Bay were analyzed using various laboratory techniques. The color, magnetic susceptibility, organic content, carbonate content, and sediment size distribution of each sample was measured to attain an overall profile of the sedimentary characteristics of the area. Using the GPS coordinates of each collection site, samples were categorized into sub-environments based on their position within the marsh. The trends within the study area and sub-environments were evaluated and interpreted. The data indicate that this marsh is a siliciclastic, fining-inland area that is frequently inundated with tidal fluctuations and storm surges. These storm surges …

The United States, China, And Climate Change: An Analysis Of The Us-China Climate Pact And Its Implications For International Climate Negotiations, Joesph Fiorile
Honors Theses
Climate change increasingly is becoming a major issue for the international community. It is contributing to rising global temperatures, rising sea levels, drought, natural disaster intensification, and ecological damage, amongst other things. A scientific consensus has emerged over recent years that implicates greenhouse gases, chief amongst them carbon dioxide, for causing global warming. Climate scientists overwhelmingly agree that the greenhouse gas effect has been caused in large part by the spike of human emissions since the dawn of the Industrial Revolution. To reverse the problem, the density of greenhouse gases in Earth’s atmosphere, especially carbon dioxide, has to be reduced. …
Direction Of Lead Diffusion In Geological Samples Using Rutherford Backscattering Sepctrometry, Andrew Mccalmont
Direction Of Lead Diffusion In Geological Samples Using Rutherford Backscattering Sepctrometry, Andrew Mccalmont
Honors Theses
A Rutherford Backscattering (RBS) analysis experiment was performed on several pyrrhotite samples in order to understand their lead (Pb) diffusive properties and determine the diffusion coefficients for Pb into the sample. The pyrrhotite samples were prepared at Rensselaer Polytechnic Institute and were subsequently annealed for one to several days at temperatures on the order of 500–800℃. A 1.1–MV Pelletron Accelerator in the Union College Ion Beam Analysis Laboratory was used to produce beams of 3.3–MeV alpha particles. The beam of alpha particles collided with the samples and the backscattered alpha particles’ energies were detected using a silicon surface barrier detector. …

Paleosol Development And Trace Fossils In The Upper Triassic Cooper Canyon Formation Of The Dockum Group In Andrews County, Texas, Michael Charles Gratzer
Paleosol Development And Trace Fossils In The Upper Triassic Cooper Canyon Formation Of The Dockum Group In Andrews County, Texas, Michael Charles Gratzer
Honors Theses
It is unknown whether a relationship exists between paleosol development and the number of burrows in a paleosol. It is also unknown whether a relationship exists between the number of burrows in a paleosol and the diameters of those burrows. This paper details the methods, results, and conclusions of an investigation of these relationships. I assess the development of several paleosols in a core sample of the Upper Triassic Cooper Canyon Formation of the Dockum Group from well B-133 in Andrews County, Texas, using development scales based on methods from Bown and Kraus (1993) and Abels et al. (2013). I …
Petrography, Mineralogy, And Geochemistry Of Greenish- And Reddish-Gray Siltstones Straddling The Vertebrate-Defined Permian–Triassic Boundary In South Africa, Jiawen Li
Honors Theses
The Permian–Triassic Mass Extinction (PTME) is considered the largest in Earth’s history, yet the terrestrial response is not well understood. The Karoo Basin, South Africa, hosts abundant exposures of terrestrial deposits that span the Permian– Triassic Boundary (PTB). The terrestrial PTB is defined by a turnover in vertebrate assemblage zones and has been associated with a transition from greenish-gray to reddish-gray siltstone. The current PTME model states that the siltstone color change is a reflection of aridification and eolian deposition, which is believed to represent rapid climate change directly linked with the event. Greenish- and reddish-gray siltstones were collected from …
Statistical Analysis Of Arsenic Concentrations In Subsurface Soils At The University Of Mississippi Field Station, David Thomas Webb
Statistical Analysis Of Arsenic Concentrations In Subsurface Soils At The University Of Mississippi Field Station, David Thomas Webb
Honors Theses
The purpose of this investigation is to determine how arsenic concentration varies in soils with respect to soil structures, grain size, soil type, and depth. The investigation was conducted at the University of Mississippi Field Station (UMFS). The UMFS is located in Abbeville, MS and is roughly 700 acres in size. It includes ponds and former agricultural fields, and lies within an internally draining basin. Seven boreholes were drilled using a direct push geoprobe and sampled. The cores obtained from the borings were then cut at one foot intervals, producing a total of 90 soil samples. Each sample was observed …
