Simulation Of Contaminant Transport From Solid Domestic Waste Disposal Sites In The Warri Deltaic Plain Sands, Warri-Effurun, Nigeria, Charles Onoriode Usiaphre

Theses, Dissertations and Culminating Projects

Protecting the groundwater resource in the Warri Deltaic Plain sand from the impact of anthropogenic contamination requires an understanding and knowledge of groundwater flow paths, transport processes and the source of contamination. This study was carried out to find out contaminant transport from solid domestic waste sites to the groundwater. The U.S. Geological Survey three-dimensional finite-difference code, MODFLOW, was used to simulate the groundwater flow. The flow pattern reveals predominantly downward flow, with major horizontal motion towards towns around Ekurede Urhobo and Ekurede Itsekiri in Warri. Simulation of advective contaminant transport using MODPATE1 for particle tracking indicates local movement of …

Petrology And Geochemistry Of The Pompton Pink Granite, New Jersey Highlands, Ian Phillip Johnson

Theses, Dissertations and Culminating Projects

The Pompton Pink Granite is a small (~1 km²), post-orogenic granitoid body located in the New Jersey Highlands. It is a mildly peraluminous (ASI or aluminum saturation index, A/CNK = molar Al₂O₃ / (CaO + Na₂O + K₂O) > 1.0) pluton composed of microcline, microperthite, quartz, oligoclase, epidote, biotite, and magnetite and is classified as a granite based on its mineral and geochemical composition using standard IUGS classification schemes. The Pompton Pink Granite shows similar major-element geochemistry to other A-type granitoids found in the New Jersey Highlands, but its trace­ element geochemistry distinguishes it from these other …

Stimulating Students’ Interest In And Curiosity About Nature Through Frequent And Brief Trips Outdoors, Joanne Claire Kornoelje

Theses, Dissertations and Culminating Projects

This study considers whether frequent and brief trips outdoors can affect students’ interest in and curiosity about nature. Recent research shows that people - and children in specific - are not spending as much time outdoors as in previous generations. This has raised concerns that today’s children will be less likely to champion environmental issues as adults, due to their lack of connection to the environment that surrounds and supports them.

I took my five sixth-grade science classes outdoors eleven times for ten-minute field trips during the 2009-10 school year. Using inquiry-based instruction, the initial trips were focused observation. Subsequent …

Rock Magnetic And Remanence Properties Of Both Synthetic Martian Basaltic Intrusions And Dropstones Along The East Antarctic Margin, To Aid In The Understanding Of The Carriers Of Crustal Magnetic Anomalies, David Michael Cuomo Jr.

Theses, Dissertations and Culminating Projects

This thesis examines potential carriers of magnetic anomalies found in remote areas where direct sampling is impossible. The areas examined are the southern hemisphere of Mars and the East Antarctic Margin. We examine the rock magnetic and remanence properties of synthetic Mars basalts and Antarctic dropstones, to predict the type and intensity of anomaly they would produce.

The anomalies measured within the Martian crust are entirely remanent magnetization and are remarkably orders of magnitude stronger than the strongest terrestrial anomaly. Two basalt compositions denoted M-type and T-type, deemed relevant to the crust of Mars, were synthesized to examine contrasts in …

Ice Sheet Dynamics Of The Past 17 Myr In Southern Mcmurdo Sound, Antarctica: A Heavy Mineral Analysis, Daniel William Hauptvogel

Theses, Dissertations and Culminating Projects

The ANtarctic Geologie DRILLing program (ANDRILL) drilled a sediment core from a sea ice platform in the Ross Sea in southern McMurdo Sound (SMS), Antarctica, in late 2007. The core site is located just to the east of the Transantarctic Mountains (TAM) along the western margin of a half graben and is a site of heavy sedimentation from the TAM, the East Antarctic Ice Sheet (EAIS), the McMurdo Volcanic Group (MVG), and the West Antarctic Ice Sheet (WAIS) and Ross Ice Shelf. The upper 650 m of the core were analyzed for heavy minerals in order to interpret ice sheet …

Characterization Of Contaminant And Biomass-Derived Organic Matter In Sediments From The Lower Passaic River, New Jersey, Usa, Nicole Michelle Bujalski

Theses, Dissertations and Culminating Projects

The lower Passaic River has been heavily contaminated during the twentieth century due to the industrial activity within its watershed. The geochemistry of four deep cores was explored using an environmental forensics approach. Pyrolysis gaschromatography/ mass spectrometry (Py-GC/MS) and grain size analysis was performed in conjunction with radiometric analysis to understand the sediment and contaminant transport patterns. The distinctive molecular finger prints were identified by employing chromatogram fingerprints, polycyclic aromatic hydrocarbon distribution, principal component analysis, and chemostratigraphy. Radiometric analysis and observations of chlorinated contaminant patterns allowed for average sample depths to be correlated to approximate ages. Additionally three distinct zones …

Talus Slope Processes In The Appalachian : An Analysis Of Rock Size And Shape On The Shawangunk Ridge, Northwestern New Jersey, Muhammad Hamidul Haque

Theses, Dissertations and Culminating Projects

Sphericity, hardness, roundness, and size of talus boulders were analyzed to understand the mass wasting process on the Shawangunk Ridge in northwestern New Jersey. Similar studies have been conducted in other localities (e.g., Lassen Peak, California and Spitsbergen, Sweden) but few works were carried out in the eastern United States, particularly in the Appalachian region. During the Pleistocene, ice sheets advanced in North America, and glacial and periglacial (soil and rock affected by ice) environments existed throughout the Appalachians. Although the periglacial climate is not present in this region right now, rock falls are still active where weak joints are …
