Wharves To Waterfalls: A Geographical Analysis Of The Massachusetts Political Economy: 1763 - 1825., David Joseph Doran
Wharves To Waterfalls: A Geographical Analysis Of The Massachusetts Political Economy: 1763 - 1825., David Joseph Doran
Geosciences Theses
This research assesses how political legislation served as the catalyst in the transformation of Massachusetts through four specific economic stages from 1763 to 1825: fishing, privateering, global maritime commerce, and textile manufacturing. The objective of this analysis is to examine how politics forced coastal merchants to invest their commercial wealth into the burgeoning interior textile industry of the New England hinterland. Vance's mercantile model best explains European settlement of New England since multiple communities developed along the Atlantic coastline of the Massachusetts Bay region. Boston, Salem, and Newburyport emerged as entrepots, which acted as intermediaries between Europe and the frontier. …
The Timing And Causes Of Illite Formation In The Cretaceous Marias River Shale, Disturbed Belt, Montana, Stephen Gerard Osborn
The Timing And Causes Of Illite Formation In The Cretaceous Marias River Shale, Disturbed Belt, Montana, Stephen Gerard Osborn
Geosciences Theses
The clay mineralogy data and K-Ar ages of I/S measured in this study agree with previous work conducted within the Disturbed Belt (Hoffman, 1976) and show that diagenetic I/S formed quickly at several different places in response to thrust sheet burial during the Laramide orogeny. The averages of concordant age values for clay sub-fractions separated from three bentonites of Cretaceous and Jurassic depositional age increase from southeast (53.6 Ma) to northwest (56.7 Ma) along the trend of the Disturbed Belt. This northwestward increase of mean ages of I/S is consistent with a thrust sheet emplacement model for the Disturbed Belt …
Implications Of Late Pleistocene Climatic Change On The Morphological Variations Of The Neanderthal, Dawn Marie Bradley
Implications Of Late Pleistocene Climatic Change On The Morphological Variations Of The Neanderthal, Dawn Marie Bradley
Geosciences Theses
In this research, the relationship of climatic changes between 130k to 28k years BP to concurrent morphological variations in Neanderthals was tested. Traditional anthropological studies attribute robust Neanderthal morphological traits as an adaptation to a cold environment. A database of previously completed terrestrial paleoclimatic reconstructions in Europe and the Mediterranean was compiled and used to create a series of GIS-generated timeslice maps. Regional climatic conditions were then related to changes in Neanderthal appearances, morphology and disappearances as evident in the archaeological record. To establish climatic conditions, existing studies were compiled from two regions: Europe and the Mediterranean. The European data …
Developing A Modular Hydrogeology Ontology Extending The Sweet Ontologies, Ajay Tripathi
Developing A Modular Hydrogeology Ontology Extending The Sweet Ontologies, Ajay Tripathi
Geosciences Theses
Application of ontologies in the environmental science will allow experts in this field to model their domain knowledge for more efficient exchange and reuse. This thesis presents a modular approach in reengineering existing upper-level ontologies to conceptualize specific domain knowledge. The aim of extending these upper-level ontologies is to tailor and transform the existing conceptual models into new ones designed for the use in a specific domain in the earth sciences. This thesis extends the upper-level Semantic Web for Earth and Environmental Terminology (SWEET)ontologies to develop ontologies for part of the hydrogeology domain. The existing SWEET ontologies are developed by …
Ozone Damage Potential To Loblolly Pine Ecosystems In Metropolitan Atlanta, Georgia, Diane Marie Styers
Ozone Damage Potential To Loblolly Pine Ecosystems In Metropolitan Atlanta, Georgia, Diane Marie Styers
Geosciences Theses
Atlanta is one of the largest metropolitan areas in the southeastern United States and is the only area in the region currently listed in “serious” 1-hour ozone nonattainment. Despite its exceedance history, impacts on Atlanta’s urban forests have not been the focus of any major studies. The purpose of this study was to examine air pollution damage to vegetation using a foliar-injury survey on Stone Mountain. The objectives of this project included 1) establishing that pollution transport from Atlanta to Stone Mountain occurs, 2) determining the magnitude of ozone concentrations near Stone Mountain and 3) assessing sensitive plant species on …
Provenance And Depositional History Of Late Pleistocene New Jersey Shelf Sediments, Roxie Jessica Turner
Provenance And Depositional History Of Late Pleistocene New Jersey Shelf Sediments, Roxie Jessica Turner
Geosciences Theses
Pleistocene New Jersey shelf sedimentology is strongly influenced by glacially driven sea level changes. A combination of regressive shoreline processes, subaerial exposure, fluvial downcutting, and deposition and reworking during transgression has influenced the NJ shelf sediment composition. Sediment provenance and transport history may be determined on a shelf environment through analysis of grain size distribution, heavy mineral content, magnetic mineral concentrations, and isotopic dating methods. A combination of surface grab and stratigraphic samples were analyzed within the study area. Relatively high percentages of heavy minerals were found in the 2 phi and 3 phi size fractions and hornblende grains provided …
Continuous Late Pleistocene Paleoclimate Record From The Southwest African Margin: A Multi-Proxy Approach, Julia Keegan Shackford
Continuous Late Pleistocene Paleoclimate Record From The Southwest African Margin: A Multi-Proxy Approach, Julia Keegan Shackford
Geosciences Theses
Late Pleistocene sediments recovered from ODP Leg 175, Site 1085 are used to generate a high-resolution (500 yr) record of continental climate change in Southern Africa. The location of Site 1085, the SW African continental slope, provides a continuous hemipelagic section with a significant terrigenous component. Terrigenous sediments are transported via fluvial and/or eolian transport mechanisms with MIS 1 being dominated by eolian transport. Analyses, including grain-size, color reflectance, biogenic sediment geochemistry (%CaCO3, %TOC, and C/N), bulk sediment geochemistry, and clay mineralogy, are used to identify continental climate conditions in southern Africa. Analyses indicate glacial/interglacial variation. Median grain-size peaks are …
