We document an apparent downward displacement of the Matuyama-Brunhes magnetic reversal by ∼20 m at Scotia Sea International Ocean Discovery Program Site U1538 (Pirie Basin) by comparison with the well-defined paleomagnetic record at nearby Site U1537 (Dove Basin). Detailed stratigraphic correlation between the two sites is possible due to similar lithologic variations. However, the two sites have distinctly different porewater geochemistry. Notably, Site U1538 indicates a greater demand for electron acceptors to oxidize organic carbon and Fe2+ enrichment below the depth of SO42− depletion. Magnetic parameters indicate enrichment of an authigenic magnetic mineral with strong remanence properties around …

The Role Of Ferrate (Vi) In The Pretreatment Of Algal Cells And Algal Organic Matters: A Review, Saige Wang, Shuyi Yang, Huan Chen, Qiufeng Lin
Department of Earth and Environmental Studies Faculty Scholarship and Creative Works
Algal blooms are caused by excessive levels of nitrogen, phosphorus, and other plant nutrients in water. Algae and algal organic matter (AOM) pose a great threat to the quality of drinking water. This manuscript offers a systematic review of algal removal by ferrate (Fe(VI)) oxidation, including the conditions for the removal of different algae by Fe(VI) and the factors affecting the removal efficiency. On this basis, the oxidation and coagulation mechanisms of algae removal by Fe(VI) are discussed. Then, the review introduces the process combining Fe(VI) pre-oxidation with aluminum sulfate action. The addition of aluminum sulfate can further enhance the …
Water Justice And Equity: The Disproportionate Effects Of Pollution On Black, Indigenous, And Other Communities Of Color, Rae Cade
Theses, Dissertations and Culminating Projects
Access to clean drinking water is a basic human right, regardless of an individual’s background. Yet, discriminatory practices in the United States have disproportionately burdened Black, Indigenous, and other people of color (BIPOC) with contaminated sources of water. Understanding how and why water is disproportionately contaminated in areas with increased diversity, and identifying and targeting areas of environmental injustice, are essential steps for ensuring future water equity. Here, I examine the drivers of inequitable access to clean drinking water within the northeastern United States. In chapter one, I look at the historical drivers of land inequity within the United States. …

The Influence Of Edaphic Factors On The Growth And Competitiveness Of Loosestrife (Lythrum Spp.), Martha Mahady
Theses, Dissertations and Culminating Projects
Wetlands are important areas in the landscape, providing important ecosystem services. Purple loosestrife (Lythrum salicaria), native to Europe and Asia, invades wetlands in North America, outcompeting native wetland plants and disrupting ecosystem services. While purple loosestrife is invasive in North America, it is not in its native range. Winged loosestrife (Lythrum alatum), a North American native congener, is not invasive in North America. Purple loosestrife from Sussex County, N.J. U.S.A. and purple loosestrife from the United Kingdom, and winged loosestrife were compared in this study. Their response to soil edaphic factors, such as seed vernalization, soil nutrients, soil pH, water, …
A Global Analysis Of Carbon And Nitrogen Stocks In Natural And Anthropogenic Soils, Shih-Chieh Chien
A Global Analysis Of Carbon And Nitrogen Stocks In Natural And Anthropogenic Soils, Shih-Chieh Chien
Theses, Dissertations and Culminating Projects
In terrestrial biomes, soils possess the highest amount of carbon and nitrogen stocks that regulate biogeochemical processes and provide ecosystem services. The amount of carbon and nitrogen stored in soils, as a balance of nutrient influxes and outfluxes, is controlled by various environmental and soil factors, while at the same time soil carbon and nitrogen stocks can be subject to anthropogenic impacts, like nutrient storage in urban soils. To inform a better, general understanding of carbon and nitrogen distribution in urban soils, the present dissertation gathers four articles (from Chapters 2 to 5, respectively) addressing different aspects of the issue, …

Theses, Dissertations and Culminating Projects
Offshore wind energy, which uses the power of winds on the seas to generate electricity, has emerged as a promising renewable energy source and an alternative for low-carbon future markets, especially during the climate crisis the world has been experiencing. However, it still raises controversial thoughts between people. Furthermore, amid the growth of the offshore wind energy market, the investigation of related topics, such as its impacts on wildlife, has become very common. Thus, this master’s thesis delves into the analysis of public and media opinion towards offshore wind energy. We use natural language processing techniques and pre-trained rule and …
Evaluation Of Heavy Metal Pollution, Water Quality, And The Effectiveness Of Remedial Sediment Dredging In The Lower Passaic River, New Jersey, Oluwafemi Soetan
Evaluation Of Heavy Metal Pollution, Water Quality, And The Effectiveness Of Remedial Sediment Dredging In The Lower Passaic River, New Jersey, Oluwafemi Soetan
Theses, Dissertations and Culminating Projects
Toxic metal pollution is a leading environmental concern for aquatic systems globally and remedial dredging has been widely employed to mitigate its harmful impacts. In terms of the short-term impacts of remedial dredging, mixed results are reported in several studies. Despite its immediate negative impacts including saturation of water with toxic metals, increased turbidity, and sediment resuspension, positive impacts can be recorded over a stabilization period of 6 – 24 months after dredging. Nevertheless, the sustainability of these recorded positive effects cannot be ascertained as some studies have reported long-term regression in remediated sites’ conditions. Evaluation of success determinants, site-measure …

Rare amphibolite in the New Jersey Highlands containing plagioclase megacrysts ≤13 cm long forms bodies 0.5 to 2 m thick that preserve a penetrative metamorphic fabric and have sharp, conformable contacts against Mesoproterozoic country rocks. The megacrystic amphibolites were emplaced as thin dikes along extensional faults between 1160 and 1130 Ma. Amphibolites contain weakly zoned, subhedral andesine megacrysts (An29–44) in a matrix of plagioclase (An18–38), magnesio-hastingsite, biotite, diopside, Fe-Ti oxides, and apatite. The whole-rock major oxide composition of the megacrystic amphibolite matrix has high TiO2 (2.07 wt.% ± 2.0%), Al2O3 (17.03 wt.% ± 0.87%), and Fe2O3t (12.84 wt.% ± 3.2%) …
Global Analysis Of Human Population Density And Blue Carbon Stocks In Mangrove Soils, Shih-Chieh Chien, Charles Knoble, Jennifer Adams Krumins
Global Analysis Of Human Population Density And Blue Carbon Stocks In Mangrove Soils, Shih-Chieh Chien, Charles Knoble, Jennifer Adams Krumins
Student Research Symposium
Recent research highlights the decline in blue carbon within mangrove ecosystems due to anthropogenic pressures. We investigate the impact of human population density on soil carbon stocks in urban mangrove forests to assess their contribution to the global carbon budget. Conducting a global analysis, we compile mangrove soil carbon data and calculate population density using European Commission records. Findings reveal a negative correlation between population density and mangrove soil carbon stocks. Specifically, when population density exceeds 300 people km−2, soil carbon decreases by 37% compared to isolated mangrove forests. However, accounting for climatic variables diminishes this negative relationship, rendering it …

Hydroclimatic Trends And Streamflow Response To Recent Climate Change: An Application Of Discrete Wavelet Transform And Hydrological Modeling In The Passaic River Basin, New Jersey, Usa, Felix Oteng Mensah, Clement Aga Alo, Duke Ophori
Department of Earth and Environmental Studies Faculty Scholarship and Creative Works
The exigency of the current climate crisis demands a more comprehensive approach to addressing location-specific climate impacts. In the Passaic River Basin (PRB), two bodies of research—hydroclimatic trend detection and hydrological modeling—have been conducted with the aim of revealing the basin’s hydroclimate patterns as well as the hydrologic response to recent climate change. In a rather novel application of the wavelet transform tool, we sidelined the frequently used Mann–Kendal (MK) trend test, to identify the hidden monotonic trends in the inherently noisy hydroclimatic data. By this approach, the use of MK trend test directly on the raw data, whose results …

Governance Policy Evaluation In The United States During The Pandemic: Nonpharmaceutical Interventions Or Else?, Danlin Yu, Shenyang Guo, Yuanyuan Yang, Linyun Fu, Timothy Mcbride, Ruopeng An
Department of Earth and Environmental Studies Faculty Scholarship and Creative Works
Scientific evidence suggests that nonpharmaceutical interventions (NPIs) effectively curb the spread of COVID-19 before a pharmaceutical solution. Implementing these interventions also significantly affects regular socioeconomic activities and practices of social, racial, and political justice. Local governments often face conflicting goals during policymaking. Striking a balance among competing goals during a global pandemic is a fine science of governance. How well state governments consume the scientific evidence and maintain such a balance remains less understood. This study employs a set of Bayesian hierarchical models to evaluate how state governments in the United States use scientific evidence to balance the fighting against …

Department of Earth and Environmental Studies Faculty Scholarship and Creative Works
The greenhouse to icehouse transition at the Eocene-Oligocene boundary (34 Ma) marked the appearance of continental-scale glaciation in Antarctica. The material recovered from Ocean Drilling Program Site 696 is the only record spanning this major climatic shift in the Weddell Sea region. Using scanning electron microscopy, quartz microtextures in 13 samples across the Eocene-Oligocene transition were analyzed to understand the degree of glacial modification and the transportation history of the >150 µm material. The quartz grains were visually grouped, characterized, and interpreted by grain outline, relief, and surface microtextures. Glacial textures are present throughout the entire interval (34.4–33.2 Ma), with …

In regional development studies, GDP serves as an important indicator for evaluating the developing levels of a region. However, due to statistical methods and possible human-induced interfering factors, GDP is also a commonly criticized indicator for less accurately assessing regional economic development in a dynamic environment, especially during a globalized era. Moreover, common data collection approaches are often challenging to obtain in real-time, and the assessments are prone to inaccuracies. This is especially true in economically underdeveloped regions where data are often less frequently or accurately collected. In recent years, Nighttime Light (NTL) data have emerged as a crucial supplementary …

This study aims to examine sentiments and themes in deploying solar energy, after the recent enactment of the Clean Energy Act. It uses text on solar energy from public dockets and open access social media platforms to fathom mass opinion. It is crucial for policymakers / stakeholders in smart and renewable energy to address challenges of energy efficiency and equity. While we deal with solar energy, many claims here are valid for other sources such as offshore wind. We propose to harness the AI-based models of VADER, SentiWordNet and TextBlob for sentiment analysis, and Latent Dirichlet Allocation (LDA) for topic …
Assessment Of Potential Impacts Of Climate Change On Hydrology And Water Resource Availability In The Passaic River Basin, New Jersey, Felix Oteng Mensah
Assessment Of Potential Impacts Of Climate Change On Hydrology And Water Resource Availability In The Passaic River Basin, New Jersey, Felix Oteng Mensah
Theses, Dissertations and Culminating Projects
Streamflow dynamics in a basin is known to be a major driver of available water resources. In the context of climate change, it is expected that global warming will accelerate the global hydrologic cycle, which will drive more intense floods and droughts leading to changes in streamflow and water resource availability. Most researchers agree that the amount and intensity of precipitation have a direct impact on runoff. Yet, there is no consensus as to how warming can affect streamflow. Evapotranspiration (ET) plays a crucial role here. However, there is a shortage of real-world observations on it. And yet, ET is …

PSEG Institute for Sustainability Studies Publications
Previous research has shown that female and Hispanic students who are underrepresented in science, technology, engineering and mathematics (STEM) face more educational barriers than their non-Hispanic, male peers. However, little research has been conducted on the effects of intersectional identities in the STEM space. In an effort to bridge the gap in underrepresented students' experience, the PSEG Institute for Sustainability Studies organizes a paid, interdisciplinary, team-based, experiential learning and internship program called the Green Teams that occurs during 10 weeks of the summer. The Green Teams Program strives to provide undergraduate students from all backgrounds–academically, economically, and demographically–an opportunity to …

Understanding gender roles in natural resource use is essential for culturally-tailored effective conservation. Despite its conservation priority, little is known about the gender roles of forest product use in Madagascar. This study used over seven years of data from 1,255 interviews on the extraction, use, and sale of forest, freshwater, and marine resources, to examine gender roles. We found that gender significantly affects natural resource use in Madagascar. While men were primarily responsible for natural resource collection, women collected nearly all resources in at least one household. Both genders collected resources, with subsistence use as the primary incentive for resource …

Trace And Rare Earth Elements Analysis Of Oligocene And Miocene Diamictites In The Cape Roberts Project, Ross Sea, Antarctica, Celina Flores Garza
Theses, Dissertations and Culminating Projects
The West Antarctic Ice Sheet is a major contributor to global sea level rise, yet its origin and dynamics are poorly known. The geochemistry of 35 diamictite samples from the CRP-1 and CPR-2A cores recovered by the Cape Roberts Drilling Project in the Ross Sea, Antarctica is evaluated to understand glacial sedimentation and flow paths during the Oligocene and Miocene, a period of warmer than present climate in the past. The major hypothesis to be tested is if the early Miocene ice sheet advance was the first major West Antarctic ice advance in the Ross Sea. The provenance of older …

Bridging The Gap: Analyzing The Relationship Between Environmental Justice Awareness On Twitter And Socio-Environmental Factors Using Remote Sensing And Big Data, Charles Knoble, Danlin Yu
Department of Earth and Environmental Studies Faculty Scholarship and Creative Works
Mounting awareness of the discriminatory distribution of environmental factors has increasingly placed environmental justice at the forefront of discussions on sustainable development, but responses to these disparities are often too little, too late. Remote sensing has emerged as a potential solution to this problem, capitalizing on the ability to capture high-resolution, spatially explicit data in near-real time. However, a conventional reliance on physical measurements and surface-level analyses risks overlooking the experiences and perceptions of affected communities. It is against this backdrop that the potential integration of remote sensing imagery and socially sensed big data such as social media data assumes …

On a daily basis, a wide range of materials including inorganic nanoparticles (NPs) inadvertently find their way into the environment. Meanwhile, intentionally used NPs, such as the new generation of nanofertilizers (NFs) are designed to enhance agronomic production. However, their physicochemical properties and not-so-well understood effects raise potential risks to the plant reproductive cycle, specifically pollen development, a subject largely absent in academic research. Even slight contamination, deformation, or aberration of pollen could have enormous impacts on the ecosystem. Thus, our objective was to evaluate the influence of various metal-based NPs on sunflower pollen morphology and its yield. Nano-formulations were …

Characterization And Origin Of Basalt-Derived Carnelian In The Mesozoic Newark Basin, New Jersey, Usa, Richard A. Volkert, Matthew L. Gorring, William H. Peck, Scott D. Stanford
Characterization And Origin Of Basalt-Derived Carnelian In The Mesozoic Newark Basin, New Jersey, Usa, Richard A. Volkert, Matthew L. Gorring, William H. Peck, Scott D. Stanford
Department of Earth and Environmental Studies Faculty Scholarship and Creative Works
Carnelian occurs locally in New Jersey in the Newark basin as medium- to coarse-size pebbles in fluvial gravel and alluvium and colluvium formed from erosion of Lower Jurassic Preakness Basalt. Vesicles and molds of glauberite are preserved on lower surfaces and botryoidal textures on the upper surfaces of some pieces. The microstructure consists of length-fast chalcedony characterized by parallel fibrous bundles overlain by repetitive, wavy extinction bands. Only peaks of ɑ-quartz and minor moganite are recognized in X-ray diffraction patterns. Carnelian contains 97–98 wt.% SiO2, ~1.0 wt.% Fe2O3, and 1.0–1.4 wt.% LOI; other major elements are <0.1 wt.%. Trace element abundances are low except for Y, Nb, Ta, W, Th, and U. Rare earth element (REE) patterns display heavy REE enrichment and large negative Eu anomalies. Most trace elements were mobilized from Proterozoic sources, whereas Si was likely derived from the alteration of basaltic glass in the Preakness. Carnelian δ18OVSMOW values are high and range from +18.3 to +31.2‰, comparable to global occurrences of volcanic rock-derived chalcedony. We propose that carnelian precipitated in the first Preakness flow from the mixing of hydrothermal fluid with meteoric water under conditions of low temperature (20–80 °C) and neutral to slightly alkaline pH.

Urban Vulnerability Analysis Based On Micro-Geographic Unit With Multi-Source Data—Case Study In Urumqi, Xinjiang, China, Jianghua Zheng, Danlin Yu, Chuqiao Han, Zhe Wang
Department of Earth and Environmental Studies Faculty Scholarship and Creative Works
This study introduces a novel approach to urban public safety analysis inspired by a streetscape analysis commonly applied in urban criminology, leveraging the concept of micro-geographical units to account for urban spatial heterogeneity. Recognizing the intrinsic uniformity within these smaller, distinct environments of a city, the methodology represents a shift from large-scale regional studies to a more localized and precise exploration of urban vulnerability. The research objectives focus on three key aspects: first, establishing a framework for identifying and dividing cities into micro-geographical units; second, determining the type and nature of data that effectively illustrate the potential vulnerability of these …

Quantifying Local And Regional Effects Of Human Development On Centennial Barrier Island Evolution : Insights From Barnegat Inlet, New Jersey, Shane Nichols-O’Neill
Theses, Dissertations and Culminating Projects
Societal benefits and ecosystem services provided by barrier islands are at risk as these landforms evolve rapidly in response to system changes including an increasing rate of sea-level rise and changing storm patterns. To prevent retreat or drowning, the expected response of natural barrier islands, and preserve benefits provided by barrier islands, significant investments are made at developed barrier islands to stabilize ocean and bay shorelines. Maintaining stable shorelines may not be sustainable in the future due to changing environmental, financial, and political conditions. Decadal to centennial-scale alongshore barrier island evolution at Long Beach Island, New Jersey is analyzed to …
