Regional Groundwater Flow And Advective Contaminant Transport Modeling In A Typical Hydrogeological Environment Of Northern New Jersey, Toritseju Oyen, Duke Ophori
Department of Earth and Environmental Studies Faculty Scholarship and Creative Works
This study develops a numerical model to simulate groundwater flow and contaminant transport in a “typical hydrogeological environment” of northern New Jersey, addressing freshwater decline. Focusing on the Lower Passaic water management area (WMA), we model chloride transport in a fractured-rock aquifer, where fracture networks control hydraulic conductivity and porosity. The urbanized setting—encompassing Montclair State University (MSU) and municipal wells—features heterogeneous groundwater systems and critical water resources, providing an ideal case study for worst-case contaminant transport scenarios. Using MODFLOW and MODPATH, we simulated flow and tracked particles over 20 years. Results show that chloride from MSU reached the Third River …

Cross-cutting issues identified …
Life Cycle Assessment Of Co-Located Floating Solar And Offshore Wind, Danela Sadikaj, Meghann Smith
Life Cycle Assessment Of Co-Located Floating Solar And Offshore Wind, Danela Sadikaj, Meghann Smith
Department of Earth and Environmental Studies Faculty Scholarship and Creative Works
Is combining floating solar and offshore wind platforms feasible for increasing energy capacity while displacing the environmental impacts that each of these systems has independently? In recent years offshore wind has become a very popular option to decarbonize the energy sector without overtaking valuable land. While floating solar is not a new technology, using solar in a marine environment is still in an experimental phase. This research proposes a Life Cycle Assessment (LCA) model of co-located solar technology within the proposed offshore wind farms near New Jersey’s coastline. While both technologies themselves are zero-emission while operating, they each require a …

Reducing Emissions And Increasing Resource Efficiency In Offshore Wind Turbines: Insight From Life Cycle Analysis, Jean Claire Pineda, Meghann Smith
Department of Earth and Environmental Studies Faculty Scholarship and Creative Works
Globally, offshore wind (OSW) has been identified as a key technology for decarbonization. While OSW’s development timeline remains uncertain in the United States, New Jersey has set the ambitious goal of 11 GW by 2040. OSW produces zero carbon emissions; however, it relies heavily on resource-intensive materials like steel, rare earth elements, and copper, and manufacturing those materials have numerous environmental impacts, including carbon emissions. Supply chain disruptions—from COVID-19, rising material costs, and geopolitical challenges—add further complexity. Previous research modelled the environmental impacts of Atlantic Shores OSW South Project with an established domestic supply chain, producing 0.013kg CO2 per kWh. …

Tracking Fall Migration With The Motus Wildlife Tracking System: The Fate Of Window-Struck And Captive-Raised Passerines, Cailin O'Connor
Theses, Dissertations and Culminating Projects
Many species of North American passerines migrate along the Atlantic flyway in the fall to reach winter habitats in the southeastern United States, the Caribbean, and Central and South America. Birds face many perils along their journeys including window strikes, which kill over one billion birds per year in the United States alone. Some birds survive the impact and may continue their migration. These birds may suffer delayed mortality or show aberrant migration due to injuries. This research seeks to understand if window-struck birds that initially survive bird-building collisions survive into the future and, if so, if they migrate effectively. …
How The Ramapough Turtle Clan Tribe Sustained Their Culture Through Ford's Environmental Exploitation, Tori Sutera
How The Ramapough Turtle Clan Tribe Sustained Their Culture Through Ford's Environmental Exploitation, Tori Sutera
Theses, Dissertations and Culminating Projects
The Ramapough Turtle Clan Tribe is an Indigenous community composed of individuals residing mainly in Ringwood, New Jersey and a few surrounding boroughs. This land holds irreplaceable significance among the community, who, after facing colonial diaspora, have ultimately resided in Ringwood. However, due to the vast effects of the Ringwood Superfund site, this community has dealt with the loss of their people and their culture. Beginning in 1967, Ford Motor Company – partial owners of the site at that time – initiated the dumping of heavily toxic materials into Cannon and Peters Mines. This dumping continued until 1971, and the …
Thermal Biology Of The Eastern Treehole Mosquito Aedes Triseriatus (Diptera: Culcidae) And Other Vertivorous Dipterans, Kelly I. Zimmerman
Thermal Biology Of The Eastern Treehole Mosquito Aedes Triseriatus (Diptera: Culcidae) And Other Vertivorous Dipterans, Kelly I. Zimmerman
Theses, Dissertations and Culminating Projects
Temperature plays a critical role in mosquito life cycle, behavior, and other ecological interactions. My dissertation analyzed how temperature affects egg hatch rates of the eastern treehole mosquito (Aedes triseriatus) and how amino acid substitutions in TRPA1 correlated with host finding through thermotaxis and the convergent evolution of vertebrate feeding/utilizing in Dipterans. As ectotherms, embryonic development and egg hatch rates are directly influenced by the water temperature mosquito eggs are oviposited into. Ae. triseriatus eggs do not hatch all at once, to avoid potentially high larval mortality rates due to their non-static oviposition sites. They engage in staggered egg hatching, …

Inferences Of Source Lithologies For Chicxulub Microtektites Using A Bayesian Approach, Jack Carter, Paolo Sanchez, Anthony J. Fuentes, Paul R. Renne, Dale H. Burns, Hermann D. Bermúdez
Department of Earth and Environmental Studies Faculty Scholarship and Creative Works
The Chicxulub impact on the Yucatán Peninsula at the Cretaceous-Paleogene boundary (KPB) was a likely contributor to the end-Cretaceous mass extinction. Glassy objects produced by quenched melt from the impact were distributed over a large region centered on the Caribbean basin and have long been known to preserve compositional information that could allow for more robust constraints on the pre-impact target lithologies. The Chicxulub-derived glasses are generally altered in most localities, but a recently discovered deposit at Gorgonilla Island, Colombia, yields a large percentage of unaltered glassy microtektites up to ∼2 mm (There is inconsistent usage of these terms in …

School of Computing Faculty Scholarship and Creative Works
For years, a main focus of ecological research has been to better understand the complex dynamical interactions between species that comprise food webs. Using the connectance properties of a widely explored synthetic food web called the cascade model, we explore the behavior of dynamics on Lotka-Volterra ecological systems. We show how trophic efficiency, a staple assumption in mathematical ecology, affects species extinction. With clustering analysis, we show how straightforward inequalities of the summed values of birth, death, self-regulation, and interaction strengths provide insight into which food webs are more enduring or stable. Through these simplified summed values, we develop a …

The Chicxulub impact is the most likely cause of the Cretaceous/Paleogene boundary (KPB) mass extinction and the only impact event in Earth's history with a globally traceable ejecta bed. Although the impact spherules are thought to represent molten or vaporized material, precise genesis and transport mechanisms remain underconstrained. Here, we show that the morphology, size, internal structure, and distribution of the spherules within the KPB deposits are related to origin and transport processes. The study of thousands of spherules from KPB deposits in Colombia, the USA, and Spain has revealed the presence of three fractions related to three different distribution …

Ferrate(Vi) Transformation Of Nitrogen In Secondary Wastewater Effluent: Implications For Water And Nutrient Management, Qiufeng Lin, Zepei Tang, Hussein I. Abdel Shafy, Yang Deng
Department of Earth and Environmental Studies Faculty Scholarship and Creative Works
Ferrate(VI) is a promising chemical agent for wastewater treatment. While targeting various contaminants, it can inevitably react with different water matrix constituents such as nitrogen (N) species. However, the reactions of ferrate(VI) with wastewater N compounds remain poorly understood. This study explores ferrate(VI)-mediated transformations of different N species in a secondary wastewater effluent. Ferrate(VI) oxidation minimally abated total dissolved nitrogen (TDN), while oxidizing dissolved organic nitrogen (DON) into dissolved inorganic nitrogen (DIN), primarily nitrate nitrogen (NO3--N), without noticeably altering ammonia nitrogen (NH3-N) levels. Consequently, ferrate(VI) treatment increased the fraction of bioavailable, soil-leachable NO3--N while lowering the portion of less bioaccessible …

Renewable energy sources are vital to help mitigate the effects of climate change, and reducing the carbon dioxide emissions of fossil fuels, e.g. the state of New Jersey has a goal of producing 100% clean energy by 2050. However, the plans for offshore wind energy by the shore of the state still brings much controversy between residents due to the wind farms’ impact on wildlife, coastline, and the people’s view from the beaches. In this context, we perform sentiment analysis on social media data to investigate people’s opinions and concerns regarding offshore wind energy. We adapt 3 machine learning models, …
Exploring Coupled Land Use -- Climate Change Impacts In The Northeast United States From 2020-2025 With Implications For Bombus Habitat Suitability, Archana Prasad
Theses, Dissertations and Culminating Projects
The combined impacts of land use and climate change pose significant challenges to bumblebee populations in the Northeast United States (NEUS), a region characterized by dense urbanization, diverse landscapes, and exposure to climate extremes. As urban and suburban areas expand, the loss of agricultural lands and open spaces alters habitat availability for bumblebees, which rely on grasslands, meadows, and forest edges for nesting and foraging. Simultaneously, the NEUS is experiencing an increase in extreme climate events, including prolonged heatwaves, heavy precipitation, and shifts in temperature patterns. Using CMIP6 climate model projections, we analyzed trends in nine climate indices. Our results …

New Jersey's Mitigation And Adaptation To Climate Change: An Economic Analysis Of The State's Societal Benefits Charge And Community Solar Energy Program, Nicole S. Provost
Theses, Dissertations and Culminating Projects
Understanding the current trajectory of New Jersey’s emissions and the existing legislation and programs implemented to help reduce emissions, it is evident that the State requires further actions to spur heightened emission reductions to reach its goals. One known impactful policy that could significantly accelerate this process is a carbon tax, which applies to emission-intensive goods. Although this policy does not currently exist in New Jersey, the State has a Societal Benefits Charge (SBC) that applies an approximate 3% charge to electricity and gas consumption on residential and commercial utility customers’ monthly energy bills, where revenues fund programs that offer …

Although mangroves provide many beneficial ecosystem services, such as blue carbon storage and coastal protection, they are currently under threat due to changes in climate conditions, such as prolonged drought exposure. Under drought conditions, evaporation exceeds precipitation and high soil salinities can lead to stunted growth and die-back. To quantify this interplay, we developed a database for low-lying and uninhabited mangrove islands in the Caribbean under various evaporation and precipitation regimes. We extracted physical and biological information from each island using remote sensing techniques and coupled it with a process-based model. We used this database to develop a model that …

Comparison Of Machine Learning-Based Predictive Models Of The Nutrient Loads Delivered From The Mississippi/Atchafalaya River Basin To The Gulf Of Mexico, Yi Zhen, Huan Feng, Shinjae Yoo
Department of Earth and Environmental Studies Faculty Scholarship and Creative Works
Predicting nutrient loads is essential to understanding and managing one of the environmental issues faced by the northern Gulf of Mexico hypoxic zone, which poses a severe threat to the Gulf’s healthy ecosystem and economy. The development of hypoxia in the Gulf of Mexico is strongly associated with the eutrophication process initiated by excessive nutrient loads. Due to the complexities in the excessive nutrient loads to the Gulf of Mexico, it is challenging to understand and predict the underlying temporal variation of nutrient loads. The study was aimed at identifying an optimal predictive machine learning model to capture and predict …

Basal materials in ice cores hold information about paleoclimate conditions, glacial processes, and the timing of past ice-free intervals, all of which aid understanding of ice sheet stability and its contribution to sea level rise in a warming climate. Only a few cores have been drilled through ice sheets into the underlying sediment and bedrock, producing limited material for analysis. The last of three Camp Century ice cores, which the U.S. Army collected in northwestern Greenland from 1963-1966 CE, recovered about 3.5 m of subglacial material, including ice and sediment. Here, we document the scientific history of the Camp Century …
Transferred Benefits In Inter-Community Beach Nourishment: A Field Study On Efficiency, Owen Thomas
Transferred Benefits In Inter-Community Beach Nourishment: A Field Study On Efficiency, Owen Thomas
Theses, Dissertations and Culminating Projects
To combat the effects of relative sea level rise and the natural erosional processes affecting the sandy, diffusive beaches of New Jersey, most communities utilize beach nourishment to stabilize their beaches. Beach nourishment, the practice of artificially widening the beach berm with sand from other areas, not only stabilizes beaches but also protects oceanfront homes from storm surges, while adding recreational space and tourism value. These benefits are reflected in increased property values, most notably in oceanfront properties. The diffusive nature of these beaches, however, means that individual nourishment events are inherently shared with neighboring communities as sand is readily …

Onset Of Antarctic Glaciation At The Eocene-Oligocene Transition In The Weddell Sea And Its Impact On Ocean Circulation, Victoria Hojnacki
Theses, Dissertations and Culminating Projects
The Eocene – Oligocene Transition (EOT) (34 Ma) represents a greenhouse to icehouse climate transition that is marked by the appearance of permanent ice sheets in Antarctica. Studying this period of climate change allows us to understand how different Earth systems reacted under changing atmospheric CO₂ conditions. Though the timing of the development of the East Antarctic Ice Sheet is well supported, the development of the West Antarctic Ice Sheet is still up for debate. Ocean Drilling Program Site 696 is the only paleoarchive of the EOT in the Weddell Sea region and offers an opportunity to better constrain the …

An Interdisciplinary Analysis Of Freshwater Wetlands With A Focus On Ecosystem Functions And Services, Michael Viteritto
Theses, Dissertations and Culminating Projects
Wetlands are one of the most productive ecosystems on Earth, though they only occupy a very small portion of the planet’s surface. They are highly sensitive ecosystems that have been undergoing an extended period of loss because of anthropogenic stress. Freshwater wetlands number among the most numerous on the planet, and in the United States they make up the overwhelming majority of wetland area. Geographically isolated wetlands (GIWs) are not directly connected to other surface water in a watershed. Freshwater wetlands provide a number of beneficial ecosystem services including climate control, erosion protection, nutrient removal and storage, flood control, food …

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 …
