Updated Pressure And Temperature Determinations For The Metapelites Of The Western Hudson Highlands, Ny, Eric W. Sonnenwald Aug 2013

Updated Pressure And Temperature Determinations For The Metapelites Of The Western Hudson Highlands, Ny, Eric W. Sonnenwald

Theses, Dissertations and Culminating Projects

Pelitic sedimentary material was deposited along the eastern margin of North America in the Mesoproterozoic (~1300-1200 Ma) in an active continental arc basin setting and was subsequently metamorphosed during the Ottawan Orogeny (~1080-1030 Ma) as a part of a closing ocean basin between two continents (Volkert and Drake, 1999). The resulting metapelitic gneisses now exposed in the western Hudson Highlands in Harriman State Park, New York were analyzed to determine the sedimentary protolith and the peak metamorphic pressure-temperature (P-T) conditions during the Ottawan Orogeny that affected this region during the final assembly of Rodinia. The protolith, a clay-bearing arkosic sandstone, …


Climate Evolution Of The Antarctic Peninsula Over The Last 1,000 Years : An Environmental Magnetism Analysis Of Two High Resolution Sediment Cores, Brendan Reilly May 2013

Climate Evolution Of The Antarctic Peninsula Over The Last 1,000 Years : An Environmental Magnetism Analysis Of Two High Resolution Sediment Cores, Brendan Reilly

Theses, Dissertations and Culminating Projects

Two marine sediment cores from very different depositional environments, off the coast of western and northeastern Graham Land, Antarctic Peninsula (AP), record high resolution climatic records of the last 1,000 years. This study finds evidence in the sedimentary magnetic signature for a regional shift from warmer to colder climatic conditions around 1100-1400 AD. The first core, from middle Barilari Bay, western AP, displays a shift from seasonally open marine conditions to sub/proximal ice shelf ca. 1100 AD, with evidence for multiple grounding line advances in the magnetic mineral distributions during the first half of the last millennium. Prior to the …


Investigating Planetary Magnetic Fields : 1. Paleosecular Variation And Relative Paleointensity Curves From Maxwell Bay, Antarctica 2. Rock Magnetic And Remanence Properties Of Natural And Synthetic Martian Basalts, Deepa Shah May 2013

Investigating Planetary Magnetic Fields : 1. Paleosecular Variation And Relative Paleointensity Curves From Maxwell Bay, Antarctica 2. Rock Magnetic And Remanence Properties Of Natural And Synthetic Martian Basalts, Deepa Shah

Theses, Dissertations and Culminating Projects

This thesis study investigates two individual projects to determine the paleomagnetic records from sediment core NBP0502-1B from Maxwell Bay Antarctica and SNC Martian meteorite Yamato-908459. Core NBP0502-1B from Maxwell Bay, South Shetland Islands, recovered a 108 m sedimentary record dating between 14.1-14.8 ka. The core has a silty-clay lithology and a calcite based radiocarbon chronology, making this an ideal site to reconstruct an independently dated record of paleosecular variation (PSV) and relative paleointensity (RPI). The interval 0-72 mbsf displays a normal sedimentary fabric, with Kmjn inclination values nearly vertical and Kint and Kmax distributed within the bedding …


Fe(Vi) As A New Chemical Agent For Treatment Of Landfill Leachate, Christopher Gravesen May 2013

Fe(Vi) As A New Chemical Agent For Treatment Of Landfill Leachate, Christopher Gravesen

Theses, Dissertations and Culminating Projects

More than 50% municipal solid waste (MSW) is being disposed of within landfills in the United States. Despite many benefits, landfills inevitably produce highly contaminated wastewater - landfill leachate. Landfill leachate represents one of the most challengeable wastewaters in the world. Refractory organic matters and ammonia nitrogen are two major persistent traditional contaminants in landfill leachate. The contaminants ought to be properly removed prior to discharge into natural water resources.

Ferrate (FeO42-) is a potential water treatment chemical agent in which iron is in its + 6 oxidation state. In engineering practice, Fe(VI) can concurrently function as …


A Historical, Empirical Analysis Of The Relationship Between Urbanization And Stream Baseflow In The Eastern United States, Jared Michael Lopes May 2013

A Historical, Empirical Analysis Of The Relationship Between Urbanization And Stream Baseflow In The Eastern United States, Jared Michael Lopes

Theses, Dissertations and Culminating Projects

The population density of the United States has more than tripled over the last century causing increased urbanization and greater anthropogenic influences in previously rural watersheds. Urbanization leads to increased impervious surfaces and the compaction of soils, both of which combine to reduce infiltration rates. Reduced baseflow can directly limit water availability for approximately half the U.S. population that depends on surficial waters for their drinking water. This project empirically investigated the baseflow-urbanization relationship on a geographic and temporal scale that has not been previously investigated. USGS river gage data in 11 eastern U.S. states (NY south of the Adirondacks, …


Citizens’ Perspectives Of Access To The Decision Making Process And Community Improvement As Determinants Of Brownfields Redevelopment Success, Shevon Jean Letang Jan 2013

Citizens’ Perspectives Of Access To The Decision Making Process And Community Improvement As Determinants Of Brownfields Redevelopment Success, Shevon Jean Letang

Theses, Dissertations and Culminating Projects

Brownfields redevelopment is acclaimed as a successful program that has revitalized struggling urban communities and returned unproductive, underutilized, and abandoned industrial and commercial properties to municipalities’ tax rolls. Despite a major brownfields' redevelopment goal being to improve the communities and their citizens' quality of life, to date, the program has not been evaluated from the mainstreams' perspective as to its impact on their neighborhoods and their quality of life. A survey of 129 citizens from urban, suburban and exsuburban municipalities in Passaic County New Jersey sought to evaluate the social outcomes of three redeveloped projects from the affected mainstreams' perspective. …
