How Can Collaborative Engagement Improve Water Quality? An On-The-Ground Perspective From The Musconetcong River, Alan R. Hunt
Sustainability Seminar Series
Partnerships are instrumental to improving water quality, especially difficult challenges like addressing non-point source pollution. Hear how over a thirty year timespan local residents worked to improve water quality, first through protecting the Musconetcong River as a National Wild and Scenic River, and then using that status to work collaboratively with federal and state agencies, non-governmental organizations, and local land owners to reduce pollution from farms and remove abandoned dams.
Effects Of Differing Environmental Conditions On Bacteriophage Jenika, Gerard Nasser
Effects Of Differing Environmental Conditions On Bacteriophage Jenika, Gerard Nasser
Theses, Dissertations and Culminating Projects
The dynamic role of bacteriophage in different environmental areas poses important questions about viral interactions with and control of bacteria. Bacteriophage play a vital role in the evolutionary track of bacteria. The evolutionary role of bacteriophage is affected by lysogenic conversion, transduction, mediated gene transfer, and the exertion of selective pressures. The objective of this research was to determine if there were changes in growth of the bacterial host Mycobacterium smegmatis and its bacteriophage Jenika given isolated changes in environmental conditions. Growth of the host, M. smegmatis, was documented using changes in optical density and growth of one of its …

Impact Of Covid-19 On Residential Waste Streams Of Montclair Township, Jeanne Huguette Perrine
Theses, Dissertations and Culminating Projects
The COVID-19 pandemic has been found to have numerous impacts on day-to-day life, everywhere around the globe. One important sector which is particularly being affected is the waste management sector. Reports from the Solid Waste Association of North America (SWANA) showed possible variations in the source and volume of solid waste generated due to the enforcement of lockdown by the authorities to contain the coronavirus outbreak (Kulkarni & Anantharama, 2020). Food waste specifically is one of the most discussed topics in the world nowadays. About one-third of the food produced for humans ends up in the trash (Nusaka, 2020). It …
Upstream Propagation Of Sea-Level Signals In Fluvio-Deltaic Environments : Time-Lags, And The Dynamics Of The Fluvial Surface, Madeline Pianta Kollegger
Upstream Propagation Of Sea-Level Signals In Fluvio-Deltaic Environments : Time-Lags, And The Dynamics Of The Fluvial Surface, Madeline Pianta Kollegger
Theses, Dissertations and Culminating Projects
The sedimentary record of fluvio-deltaic environments holds clues to past climate and sea level change. Although theories for stratigraphic interpretation generally rely upon the assumption that the fluvial surface responds uniformly to sea level changes, recent theoretical work suggests that changes in the relief and concavity of the fluvial surface can influence the propagation of sea level information upstream, and result in geologically long-lived lags in the system response. We test this theoretical result using measurements from an evolving experimental delta subject to sea-level cycles. As predicted by the theoretical results, during sea-level fall the relief increases and the fluvial …

The New York Times has described Heidi Latsky as a “choreographer and dancer of uncommon intelligence and fluidity” and has written that, for her, “there are no unbeautiful bodies and no bodies incapable of dancing. In what some might call disability, she finds possibility.” With her ongoing series On Display, she turns a cast of diverse bodies into a sculptural installation, appropriating the notion of the body as spectacle and addressing society’s tendency to objectify, judge, and stigmatize people who are different from ourselves. On the stage of the Kasser, in collaboration with lighting designer Robert Wierzel, New York Live …

Loss of tidal wetlands is a world-wide phenomenon. Many factors may contribute to such loss, but among them are geochemical stressors such as exposure of the marsh plants to elevated levels on hydrogen sulfide in the pore water of the marsh peat. Here we report the results of a study of the geochemistry of iron and sulfide at different seasons in unrestored (JoCo) and partially restored (Big Egg) salt marshes in Jamaica Bay, a highly urbanized estuary in New York City where the loss of salt marsh area has accelerated in recent years. The spatial and temporal 2-dimensional distribution patterns …

Department of Earth and Environmental Studies Faculty Scholarship and Creative Works
The Paleocene-Eocene Thermal Maximum (PETM; 56 Ma) is considered to be one of the best analogs for future climate change. The carbon isotope composition (δ13C) of n-alkanes derived from leaf waxes of terrestrial plants and marine algae can provide important insights into the carbon cycle perturbation during the PETM. Here, we present new organic geochemical data and compound-specific δ13C data from sediments recovered from an early Cenozoic basin-margin succession from Spitsbergen. These samples represent one of the most expanded PETM sites and provide new insights into the high Arctic response to the PETM. Our results reveal …

Department of Earth and Environmental Studies Faculty Scholarship and Creative Works
The Eocene-Oligocene transition (EOT) marks the onset of Antarctic glaciation at 33.7 Ma. Although the benthic oxygen isotope record defines the major continental ice sheet expansion, recent sedimentary and geochemical evidence suggests the presence of earlier ephemeral ice sheets. Sediment cores from Ocean Drilling Program Legs 119 and 188 in Prydz Bay provide an archive of conditions in a major drainage system of East Antarctica. We study biomarker and microfossil evidence to discern how the vegetation and climate shifted between 36 and 33 Ma. Pollen was dominated by reworked Permian Glossopterid gymnosperms; however, penecontemporaneous Eocene pollen assemblages indicate that some …

The National Wild and Scenic Rivers Act protects less than ¼ of a percent of the United States’ river miles, focusing on free-flowing rivers of good water quality with outstandingly remarkable values for recreation, scenery, and other unique river attributes. It predates the enactment of the Clean Water Act, yet includes a clear anti-degradation principle, that pollution should be reduced and eliminated on designated rivers, in cooperation with the federal Environmental Protection Agency and state pollution control agencies. However, the federal Clean Water Act lacks a clear management framework for implementing restoration activities to reduce non-point source pollution, of which …

International Ocean Discovery Program (IODP) Expedition 382 in the Scotia Sea’s Iceberg Alley recovered among the most continuous and highest resolution stratigraphic records in the Southern Ocean near Antarctica spanning the last 3.3 Myr. Sites drilled in Dove Basin (U1536/U1537) have well-resolved magnetostratigraphy and a strong imprint of orbital forcing in their lithostratigraphy. All magnetic reversals of the last 3.3 Myr are identified, providing a robust age model independent of orbital tuning. During the Pleistocene, alternation of terrigenous versus diatomaceous facies shows power in the eccentricity and obliquity frequencies comparable to the amplitude modulation of benthic δ18O records. …
Community-Scale Beach Nourishment And Groin Construction Decisions Along Human-Modified Coasts : The Interplay Between Socioeconomics, Coordination, Tourism, And Shoreline Change, Arye Max Janoff
Theses, Dissertations and Culminating Projects
In response to coastal erosion driven by storms, sea-level rise, and local gradients in sediment supply, communities defend their homes and maintain beach recreation by widening beaches via soft engineering (i.e., beach nourishment) or hard engineering (i.e., groins). Past research has found that, at regional scales, the net effect of these interventions has in many cases not only counteracted historically observed beach erosion, but has reversed erosional trends, on average shifting shorelines seaward. While groins trap sediments locally at and upcoast of the structure relative to the direction of alongshore transport, however, they often have adverse downcoast impacts, resulting in …

The largest mass extinction event in the Phanerozoic, known as the end-Permian mass extinction (or EPME, ca. 252 Ma) is coincident with the main eruption phase of Siberian Traps volcanism (ca. 252 to 250 Ma), a large igneous province (LIP). This LIP is estimated to have a volume larger than 2 × 106 km3 and to have released both mantle carbon dioxide (CO2) through extrusions and thermogenic methane (CH4) and carbon dioxide (CO2) through intrusions. The climatic consequences of these greenhouse gases is detrimental to both marine and terrestrial life and may have delayed the recovery of ecosystems …

Mining Learner-Friendly Security Patterns From Huge Published Histories Of Software Applications For An Intelligent Tutoring System In Secure Coding, Xu Du, Aparna S. Varde
Department of Computer Science Faculty Scholarship and Creative Works
Security patterns are proven solutions to recurring problems in software development. The growing importance of secure software development has introduced diverse research efforts on security patterns that mostly focused on classification schemes, evolution and evaluation of the patterns. Despite a huge mature history of research and popularity among researchers, security patterns have not fully penetrated software development practices. Besides, software security education has not been benefited by these patterns though a commonly stated motivation is the dissemination of expert knowledge and experience. This is because the patterns lack a simple embodiment to help students learn about vulnerable code, and to …

Identification Of Ice-Rafted Debris In The Weddell Sea To Characterize Glaciation At The Eocene-Oligocene Transition, Josie Horowitz
Theses, Dissertations and Culminating Projects
At the Eocene-Oligocene transition (EOT), approximately 34 million years ago (Ma), the Earth’s climate changed from a warm greenhouse to a cooler climate which resulted in ice-sheet growth and stable continental-scale ice sheets in Antarctica. Hole 696B of the Ocean Drilling Program Leg 113 drilled in 650 m of water depth on the South Orkney Microcontinent spans the entire EOT. Cores 53R and 54R are dated at lower Oligocene (~33.1 to ~33.5 Ma) and total ~14 meters in thickness from ~549 to ~564 mbsf. Ice-rafted debris (IRD) in sediment cores gives insight into the extent of glaciation in West Antarctica, …

Testing residential soil and paint for lead provides actionable information. By showing where and how much lead exists on the residence, it allows one to quantify risk and determine the best ways to reduce exposure along with the corresponding health and financial costs. For these reasons, several federal and state programs offer outreach to audiences on the benefits of testing residential soil and paint for lead. Not all individuals who know about lead’s adverse health effects, however, test their residence for lead, potentially limiting the actionable information that could have helped to reduce their exposure. Such individuals represent a challenge …

Modeling Biotic & Abiotic Drivers Affecting Biogeomorphic Coastal Foredunes, Bianca Charbonneau
Modeling Biotic & Abiotic Drivers Affecting Biogeomorphic Coastal Foredunes, Bianca Charbonneau
Sustainability Seminar Series
Coastal dunes are exceptionally dynamic terrestrial habitats that will only grow increasingly vulnerable with climate change. A structured approach to protect and restore these and other coastal biogeomorphic interface habitats is needed to maintain their invaluable ecosystem services. Vegetation in these habitats acts as ecosystem engineers such that, to achieve this, one must understand and accurately forecast vegetation dynamics at the nexus of shifting abiotic conditions and drivers of change. We developed a process-based model for coastal dune vegetation ecology, specifically, growth, density, and colonization as it affects and is affected by shifting habitat topography and storm event impact. The …

The aim of this work was to evaluate the transformation of manganese oxide (hausmannite) by microscopic filamentous fungus Aspergillus niger and the effects of the transformation on mobility and bioavailability of arsenic. Our results showed that the A. niger strain CBS 140837 greatly affected the stability of hausmannite and induced its transformation into biogenic crystals of manganese oxalates—falottaite and lindbergite. The transformation was enabled by fungal acidolysis of hausmannite and subsequent release of manganese ions into the culture medium. While almost 45% of manganese was bioextracted, the arsenic content in manganese precipitates increased throughout the 25-day static cultivation of fungus. …

We document magnetic mineral diagenesis with high-resolution magnetic susceptibility, hysteresis, isothermal remanent magnetization, and other rock magnetic measurements through a shallow sulfate-methane transition (SMT) at Perseverance Drift—a high-accumulation rate Holocene biosiliceous Antarctic marine sediment deposit. The structure of the SMT is defined with porewater measurements from the same core, allowing direct comparison. Dissolution of the detrital (titano)magnetite assemblage, with preferential dissolution of stochiometric magnetite, occurs in the upper SMT. Higher coercivity magnetic minerals dissolve more slowly, continuing to dissolve through the entire SMT and could be a source of ferric iron for microbial respiration following exhaustion of porewater sulfate, as …

The Use Of Green Pond Conglomerate As Building Stone In Morris County, New Jersey, Gregory A. Pope
The Use Of Green Pond Conglomerate As Building Stone In Morris County, New Jersey, Gregory A. Pope
Department of Earth and Environmental Studies Faculty Scholarship and Creative Works
Green Pond Conglomerate (GPC) is a maroon colored quartzite with white quartz pebbles, a classic “puddingstone”. GPC derives from a NW-SW-trending sliver of Paleozoic sediments, the “Green Pond Outlier”, surrounded by older metamorphic and igneous rocks of Morris and Passaic Counties. Buildings, retaining walls, field fences, and monuments incorporate the durable and attractive stone, in a distinct geographic area of Morris County. Several instances of structures completely constructed or faced with GPC occur in and around Morristown, limited to affluent houses and one prominent church. In these cases, GPC stones were dressed and faced, a labor-intensive effort. Elsewhere in the …
Low-Cost Adsorbents For Urban Stormwater Pollution Control, Yang Deng
Low-Cost Adsorbents For Urban Stormwater Pollution Control, Yang Deng
Department of Earth and Environmental Studies Faculty Scholarship and Creative Works
Stormwater represents a major non-point pollution source at an urban environment. To improve the treatment efficacy of stormwater infrastructure, low-cost adsorbents have increasingly gained attention over the past decades. This article aims to briefly discuss several key aspects and principles for utilization of low-cost adsorbents for urban stormwater treatment. To determine whether a low-cost adsorbent is suitable for stormwater treatment, two aspects should be carefully assessed, including: 1) its adsorption mechanisms and behaviors that can influence the binding strength, adsorption kinetics, and treatment capacity; and 2) unwanted chemical leaching patterns that can affect the extent of water quality degradation. Furthermore, …

A 23 M.Y. Record Of Low Atmospheric Co2, Ying Cui, Brian A. Schubert, A. Hope Jahren
Department of Earth and Environmental Studies Faculty Scholarship and Creative Works
Current atmospheric CO2 concentration is known to be higher than it has been during the past ~800 k.y. of Earth history, based on direct measurement of CO2 within ice cores. A comparison to the more ancient past is complicated by a deficit of CO2 proxies that may be applied across very long spans of geologic time. Here, we present a new CO2 record across the past 23 m.y. of Earth history based on the δ13C value of terrestrial C3 plant remains, using a method applicable to the entire ~400 m.y. history of C3 photosynthesis on land. Across the …
