Detrital Tourmaline As An Indicator Of Provenance: A Chemical And Sedimentological Study Of Modern Sands From The Black Hills, South Dakota, David Brent Viator

LSU Master's Theses

Detrital tourmaline has proven useful as a provenance indicator mineral of ancient sedimentary/metasedimentary units due to its presence in many rock types, chemical responsiveness to environments of formation, complex and variable chemical compositions, high resistance to chemical and mechanical weathering, and stability through diagenesis and metamorphism. This study further establishes detrital tourmaline as a provenance indicator mineral by examining the chemical and sedimentological relationships between modern detrital tourmalines in the sediments of the Black Hills, South Dakota, USA, and in situ tourmalines from southern Black Hills’ tourmaline-bearing metasedimentary rocks, granites, and rare-element enriched pegmatites. Results show that detrital tourmaline is …

Experimental Investigation Of Elemental Incorporation In The Otoliths Of Larval And Juvenile Fish: Implications For Use As Environmental Recorders, Gretchen Bath Martin

Biological Sciences Theses & Dissertations

Innovative techniques for discerning fish stocks, identifying nursery habitats, locating spawning sites, tracing larval transport pathways, and quantifying the degree of population connectivity are required to meet the goals of sustainable management of marine capture fisheries. One of the most promising techniques is the use of elemental signatures in fish otoliths (ear stones), which record valuable life history data and serve as the link between fish and their environment. To validate the assumption that otolith elemental composition is a function of water elemental concentrations, and to address the possible effects of external variables such as temperature and salinity, the composition …

The Effects Of Student Manipulated Lewis Structure Models On Chemistry Achievement According To Cognitive Level, Kimberly M. Ross

Dissertations and Theses @ UNI

The purpose of this study was to determine if there was a correlation between teaching method or cognitive development and achievement in a unit on Lewis electron dot structures. Forty-six students were taught a unit on Lewis electron dot structures using the traditional paper and pencil method. Thirty-eight students were taught the same unit using a manipulative model instead of the traditional method. Both groups of students were given pre and post-tests on Lewis electron dot structures and their gains after instruction were measured. The Group Assessment of Logical Thinking measured student's cognitive level. Students were categorized as concrete, transitional …

Predators And Life Histories Shape Lestes Damselfly Assemblages Along A Freshwater Habitat Gradient, Robby Stoks, Mark A. Mcpeek

Dartmouth Scholarship

Survey data from New England showed that assemblages of Lestes dam- selflies are organized along the entire gradient of pond permanence and predator presence. One assemblage occupies vernal ponds lacking large dragonfly predators and fish; four are largely confined to temporary ponds that typically contain dragonfly predators; one dom- inates fishless permanent ponds and lakes where dragonflies are the top predators; and one dominates permanent ponds and lakes where fish are the top predators. We determined the role of life history and predation in maintaining this striking pattern by conducting a series of transplant experiments in the field and a …

Development Of Diagnostic Approaches To Determine Sources Of Anthropogenic Stress Affecting Benthic Community Conditions In The Chesapeake Bay, Daniel M. Dauer, Michael F. Lane, Roberto J. Llansó

Benthic Applications

Benthic macrofauna are an important component of estuarine ecosystems. These organisms are a food source for higher trophic levels including fishes and crabs (Virnstein 1977, 1979; Holland et al. 1980; Dauer et al. 1982) and birds (Botton 1984; Quammen 1984). Benthic macrofauna affect both the physical and chemical properties of the sediment and the overlying water column (e.g., Rhoads and Young 1970; Rhoads 1973; Aller 1978, 1980), influence nutrient cycling (Rowe et al 1975; Zeiteschel 1980; Flint and Kamykowski 1984), and are capable of directly controlling phytoplankton biomass in the water column (Cleorn 1982; Officer et al 1982; Cohen et …

Effects Of Developmental Activities On Streamside Salamander Communities In Boone County, West Virginia, Mindy S. Hamilton

Theses, Dissertations and Capstones

A study was conducted from May 1998 through June 1999 in three streams associated with mountaintop mining and valley fills in Boone County, West Virginia. Streamside salamander communities were monitored in these streams, as well as in two relatively undisturbed reference streams in the region, using refugia bags, rock-on-rock methodology, and day surveys. The relative abundance of salamanders was compared between the streams in order to detect effects of the associated valley fills to downstream biota. Relative abundance was lower in two of three streams associated with valley fills as compared to the reference streams. However, there was no significant …

Hydrogeology Of The Sistema Huautla Karst Groundwater Basin Association For Mexican Cave Studies Bulletin, Vol. 9, 2002, James H. Smith Jr.

KIP Articles

Sistema Huautla, in 2002 the world’s seventh deepest cave, at 1,475 meters, is one of the most complex vertical drainage systems in the world. The focus of this research was to study the geology, karst hydrology, and speleology of the Sistema Huautla cave system. Literature review and subsequent field mapping identified the geologic formations and tectonic structures that Sistema Huautla and tributary caves are developed within. Structural geology studies within the aquifer indicate that base-level conduits in the mapped portion of the aquifer are formed along a major normal fault system called the Sistema Huautla Fault. Conduits in other sections …

On The Relative Role Of Convection, Chemistry, And Transport Over The South Pacific Convergence Zone During Pem-Tropics B: A Case Study, Céline Mari, Carine Saüt, Daniel J. Jacob, Amanda Staudt, Melody A. Avery, William H. Brune, Ian Faloona, Brian G. Heikes, Glen W. Sachse, Scott T. Sandholm, Hanwant B. Singh, David Tan

Graduate School of Oceanography Faculty Publications

A mesoscale 3D model (Meso‐NH) is used to assess the relative importance of convection (transport and scavenging), chemistry, and advection in the vertical redistribution of HO_x and their precursors in the upper tropical troposphere. The study is focused on marine deep convection over the South Pacific Convergence Zone (SPCZ) during the PEM‐Tropics B Flight 10 aircraft mission. The model reproduces well the HO_x mixing ratios. Vertical variations and the contrast between north and south of the SPCZ for O₃ are captured. Convection uplifted O₃‐poor air at higher altitude, creating a minimum in the 9–12 km …

A zero‐dimensional (0‐D) model has been applied to study the sources of hydrogen oxide radicals (HO_x = HO₂ + OH) in the tropical upper troposphere during the Pacific Exploratory Mission in the tropics (PEM‐Tropics B) aircraft mission over the South Pacific in March–April 1999. Observations made across the Southern Pacific Convergence Zone (SPCZ) and the southern branch of the Intertropical Convergence Zone (ITCZ) provided the opportunity to contrast the relative contributions of different sources of HO_x, in a nitrogen oxide radical (NO_x)‐limited regime, in relatively pristine tropical air. The primary sources of HO_{x …}

The Distribution Of Airborne Coal Dust In Soil Profiles Of Norfolk, Va And Its Implication For Arsenic Loading To These Soils, William Joseph Bounds

OES Theses and Dissertations

Norfolk, Virginia is home to the Northern Hemisphere's largest coal terminal the Lamberts Point Docks. The coal loading process of this terminal creates large amounts of coal dust, which subsequently is distributed throughout the local region by atmospheric transport and deposition. While the coal dust itself poses only minor health hazards, certain trace elements within the coal, particularly arsenic, may pose environmental as well as significant health hazards. Within coal, arsenic occurs primarily in the mineral pyrite. As pyrite in the coal dust is subsequently oxidized via exposure to the atmosphere and/or meteoric water, arsenic may be released to the …

Faculty Bibliography 2000s

On April 15 and 19, 1998, two intense dust storms were generated over the Gobi desert by springtime low-pressure systems descending from the northwest. The windblown dust was detected and its evolution followed by its yellow color on SeaWiFS satellite images, routine surface-based monitoring, and through serendipitous observations. The April 15 dust cloud was recirculating, and it was removed by a precipitating weather system over east Asia. The April 19 dust cloud crossed the Pacific Ocean in 5 days, subsided to the surface along the mountain ranges between British Columbia and California, and impacted severely the optical and the concentration …

Analysis Of Hydrocarbon Materials By Use Of Nonpolar Matrices In Matrix-Assisted Laser Desorption/Ionization Mass Spectrometry (Maldi-Ms)., Stephen Francis Macha

LSU Historical Dissertations and Theses

In this study, polyaromatic hydrocarbon compounds including anthracene, pyrene, acenaphthene and perylene were investigated as nonpolar matrices in matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS) for the analysis of selected nonpolar analytes. First, the influence of matrix and the analyte ionization potentials on a charge-transfer ionization mechanism were determined. Results of these studies demonstrated that formation of radical molecular cations in MALDI-MS depends on the ionization energy difference between the matrix and the analyte. Charge-transfer ionization occurs only when the ionization potential of the matrix is higher than that of the analyte. Next, nonpolar matrices were investigated for the analysis of …
