δ<super>15</super>n in mollusk shells as a potential paleoenvironmental proxy for nitrogen loading in chesapeake bay

Black, Heather Dawn (University of Alabama Libraries, 2014)

Crassostrea virginica is one of the most common oyster species in North America and is frequently found in archaeological sites and sub-fossil deposits, especially in the eastern US. Although there have been several ...
A comparison of continental extension estimates across the margins of the Woodlark Basin, Papua New Guinea

Nazlim, Berg (University of Alabama Libraries, 2017)

Previous studies have shown that depth dependent extension is common across rifted margins. A discrepancy exists between the estimates of extension made through whole lithosphere/crust vs fault heave calculations (for ...
A comparison of pre-treatment methods for δ^15 N analysis in mollusk shells

Hansen, Jestina Anne (University of Alabama Libraries, 2011)

Two sample preparation methods, acid pretreatment and no pretreatment, for δ^15 N analysis in mollusk shells were compared on sample splits from three common Gulf of Mexico and North Atlantic mollusks (Mercenaria spp., ...
A geophysical characterization of stratigraphy in the Eastern Black Warrior Basin underlying Gorgas Power Generation Plant, Walker County, Alabama

Rutter, Rachael S. (University of Alabama Libraries, 2012)

The Black Warrior Basin is a triangular shaped foreland basin located in the southeastern United States between the Appalachian and Ouachita fold and thrust belts. The basin has the potential to provide geologic carbon ...
A high-resolution hydroclimate record of the last three millennia from a cored stalagmite at Desoto Caverns (Alabama, USA)

Dhungana, Rajesh (University of Alabama Libraries, 2010)

Late Holocene climate changes in the Southeast USA are poorly documented due to the paucity of high-resolution paleo-records. This study provides high-resolution records of rapid hydroclimate changes in the Southeast over ...
A model of the crust and upper mantle structure of the Hellenic and Cyprus subduction zones constrained by gravity and seismic data

Alemdar, Suleyman (University of Alabama Libraries, 2015)

The Aegean-Anatolian region is one of the most dynamically complex and seismically active tectonic settings on Earth. The dynamic evolution of this region is dominated by the African plate subduction along the Hellenic and ...
Anthropogenic and environmental drivers of the input and uptake of dissolved organic matter in temperate streams

Shang, Peng (University of Alabama Libraries, 2019)

Dissolved organic matter (DOM) is a complex mixture of organic compounds and plays an essential role in regulating substrate and energy flows in aquatic ecosystems. However, environmental factors and biogeochemical mechanisms ...
Application of phosphate and surfactant-modified zeolite for remediation/attenuation of trace elements in soil and coal fly ash

Neupane, Ghanashyam (University of Alabama Libraries, 2012)

This dissertation presents results of a research work aimed at understanding and addressing trace element contamination sourced by coal fly ash and arsenic trioxide herbicide. Both alkaline and acidic fly ash samples were ...
Aqueous geochemistry of a sulfurous freshwater spring: implications for sulfur cycling and resident microbial communities

Morrissey, Tacoma Nicole (University of Alabama Libraries, 2014)

Blount Springs offers a sulfide-rich environment inhabited by a diverse microbial community in which to study the sulfur redox reactions and the microbially mediated processes via the analysis of sulfur isotopes of sulfide ...
Are the mantle lithosphere and lower crust preferentially thinned during continental rifting?

Tew, Kalyn J. (University of Alabama Libraries, 2018)

Worldwide, estimates of extension in rift zones vary greatly depending on the method used to calculate the extension. This variability is the result of the discrepancy between different methodologies and may be the result ...
Assessment of the petroleum generation potential of the Neal Shale in the Black Warrior Basin, Alabama

Legg, Joel Arthur (University of Alabama Libraries, 2014)

The Neal shale, the organic-rich interval of the Floyd Shale located in the Black Warrior Basin of Alabama and Mississippi, has attracted recent attention as a potential economic source of hydrocarbons. X-ray diffraction ...
Biogeochemical analysis of late cretaceous vertebrate fossils of western Alabama, USA

Harrell, Terry Lynn (University of Alabama Libraries, 2016)

In the past, vertebrate paleontologists in Alabama focused primarily on classical methods of investigation, for example, by examining the gross anatomy of fossilized skeletal elements. More recently, new methods were ...
Biomineralization of giant clam shells (tridacna gigas): implications for paleoclimate applications

Gannon, Michelle E. (University of Alabama Libraries, 2016)

The giant clam, Tridacna gigas, is an important faunal component of Indo-Pacific reef ecosystems, for which its shell is often used as an environmental archive for modern and past climates. This thesis is a study of the ...
Biostratigraphy of the Bluffport Marl Member of the Demopolis Chalk, Cretaceous of Alabama

Newman, Harry Ellsworth, III. (University of Alabama Libraries, 1969)

The Bluffport Marl Member of the Demopolis Chalk was sampled to find what lithologic and paleontologic variations occur along the strike of this unit. The Bluffport Marl Member has been traced in Alabama from Sumter County ...
Biostratigraphy, paleogeography, and paleoenvironments of the Upper Cretaceous (Campanian) northern Mississippi Embayment

Ebersole, Sandy (University of Alabama Libraries, 2010)

Most paleogeographic and paleoenvironmental reconstructions of the northern Mississippi Embayment during the Late Campanian (Late Cretaceous) illustrate a generalized gulf between central Mississippi and Arkansas stretching ...
Bulk chemical composition and mineral effects on grain conductivity and ice nucleation affinity of volcanic ash

Cloer, Shelby (University of Alabama Libraries, 2017)

Volcanic lightning is a common phenomenon during explosive eruptions, occurring as vent discharges, near-vent discharges, and plume lightning. Plume lightning is most similar to thunderstorm lightning, where volcanic ash ...
Carbonation of flue gas desulfurization gypsum for CO2 sequestration

Riddle, Jonathan B. (University of Alabama Libraries, 2021)

The IPCC asserts that to prevent a 2°C global temperature increase by the year 2050, CO2 must be removed from the atmosphere by sequestration. The goal of this study was to use FGD gypsum for CO2 mineralization and ...
Cave air and dripwater variability in Cathedral Caverns, Alabama

McKay, Kathleen Kingry (University of Alabama Libraries, 2016)

Monthly monitoring of dripwater (δ18O, δD, [DIC], δ13CDIC, and pH) and air (pCO2 and δ13CCO2) chemistry from within Cathedral Caverns (Grant, AL) was conducted for 12 months (January 2015-December 2015) to better characterize ...
Cave air C O_2 and drip-water geochemical variability at Desoto Caverns: implications for speleothem-based paleoclimate studies

Dhungana, Rajesh (University of Alabama Libraries, 2017)

This study has addresses the question whether speleothems from DeSoto Caverns (Childersburg, AL) can be used as paleoclimate archives for the Southeast USA. The monitoring program encompassed determination of cave air CO2, ...
Cenozoic landscape evolution of a post-compressional orogenic wedge: intermontane basin development and sediment dispersal patterns, Renova Formation, southwest Montana

Rothfuss, Jennifer L. (University of Alabama Libraries, 2010)

Sediment pathways and landscape evolution are useful proxies for refining the current understanding of crustal and surficial processes that initiated Paleogene post-compressional demise of the Cordilleran orogenic wedge ...
