Geosciences Faculty Publications and Presentations
In this study, we examine whether updating an interactive hazard map using recommendations from the literature improves user map comprehension. Analyses of experimental data collected from 75 university students revealed that map comprehension scores were not significantly better for those who viewed a “best practices” map compared to those who viewed an existing version. This may be because the existing map was itself better than most other interactive maps. Additionally, we found map comprehension levels to have significant positive relationships with objective tests, but not self-reported measures of spatial ability. Moreover, self-reported spatial ability had statistically significant, but only moderately ...
A Comparison Of Tribal Sovereignty, Self-Determination, And Environmental Justice At The Epa’S Onondaga Lake And Tar Creek Superfund Sites, 2020 The Graduate Center, City University of New York
A Comparison Of Tribal Sovereignty, Self-Determination, And Environmental Justice At The Epa’S Onondaga Lake And Tar Creek Superfund Sites, Thomas Clark
All Dissertations, Theses, and Capstone Projects
The Environmental Protection Agency’s Superfund program mandates that Native American tribes are afforded the same treatment as states in the implementation of environmental remediation projects; however, the degree of coordination and consultation between the EPA and sovereign tribal governments varies widely between sites. Two of the Superfund program’s highest profile sites with Native American interest, northeast Oklahoma’s Tar Creek and central New York’s Onondaga Lake, are characterized by such a disparity in tribal participation. While Oklahoma’s Quapaw Tribe would ultimately enter into a number of cooperative agreements with the EPA for direct control over remedial ...
Updating The Electronics Cycle: Improving Us E-Waste Management Practices, 2020 The University of San Francisco
Updating The Electronics Cycle: Improving Us E-Waste Management Practices, Martin Cooper
Master's Projects and Capstones
The United States is one of the largest producers of electronic waste (e-waste), partly due to a lack of federal legislation to regulate e-waste disposal and transport. Increased collection, recycling, and reuse of electronics can reduce pollution from hazardous metals and chemicals found in e-waste, lower the carbon footprint of the electronics industry, and protect the health of workers in the global waste management sector. This paper examines case studies of e-waste management strategies in European Union member nations and US states, and identifies ways to integrate those strategies in US federal and state policy. This paper finds that extended ...

Year-long Analysis of the Water Quality of White Horn Brook
Sponsor: Thomas Boving (Geological Sciences)
Water is the foundation for all life on earth and is the most vital resource on this planet. Despite this, oceans and waterways all over the world are being polluted and exploited in ways detrimental to their fundamental hydrologic functions. For instance, excess nitrate levels can lead to eutrophication which gives rise to harmful algae blooms. Low pH can cause the breakdown of CaCO3 exoskeletons of organisms, such mollusks. High temperature variations are major stressors to living things and can cause ...
Private Land, Public Trust: Strategic Conservation Planning For Public Wildlife On Private Lands Through The Usfws Partners For Fish And Wildlife Program, Clint Wirick
All Graduate Plan B and other Reports
Law requires federal agencies to develop long-term strategic plans. Strategic plans define goals, objectives, and performance measures defining how the agencies and programs will reach their stated goals. U.S. Fish and Wildlife Service’s Partners for Fish and Wildlife (PFW) develops strategic plans every five years. Each individual state develops a plan for their respective state. Those state plans are compiled for the region and become part of Regional Comprehensive Strategic Plan. The current strategic plan expires in 2021. States will begin the strategic planning process in 2020. In Utah, PFW staff will also begin developing a strategic plan ...

384— Chimney Swift Conservation Project, Brian Zapfel, Hiina Asami, Brooke Francis
The Chimney Swift Project is a student team promoting conservation for Chimney Swifts, a species of small insectivorous bird found throughout the eastern United States and Canada during their breeding season. In a natural setting, Chimney Swifts nest in hollow trees which were common in the old-growth forests prominent in the United States before European colonization. Currently, Chimney Swifts population is on a steep decline primarily due to human caused habitat destruction. Overall, 75% of the population has been lost since 1970. Our project aims to promote the conservation of Chimney Swifts through the construction of a nesting tower and ...
Surveillance Of Microplastic Pollution In Central Virginia Freshwater Ecosystems, 2020 Liberty University
Surveillance Of Microplastic Pollution In Central Virginia Freshwater Ecosystems, Alexandra Reddy
Senior Honors Theses
Aquatic organisms often mistake microplastic particulates (MP) as food and inadvertently ingest the particulates, which can biomagnify through the food chain. While MP ingestion is well-researched in the marine environment, little is known about microplastics in freshwater ecosystems. This project explores MP occurrence in an ecologically significant freshwater invertebrate: crayfish. Crayfish from two Central Virginia streams are collected to identify MP in the digestive tracts and gill filaments, and characterize the MP using analytical chemistry techniques. It was determined that MP were present in the digestive tracts and gill filaments of crayfish collected from both streams, and that MP frequency ...

Environmental Nonprofits emerged over the years to attend to the environmental needs of communities and individuals, as well as address environmental issues that concern the public. These issues are usually those that have been neglected, given insufficient attention, or cannot be singularly handled by the government. In advocating for coastal resilience, environmental nonprofits have been identified in the literature as actors with critical roles in addressing coastal issues such as sea-level rise, flooding and shoreline management. In recent times, shoreline management has emerged as one of the foremost areas of focus expedient for the achievement of coastal resilience, and the ...
Using Electrocoagulation To Remove Perfluoroalkyl And Polyfluoroalkyl Substances (Pfas) From Contaminated Water, 2020 University of Nebraska-Lincoln
Using Electrocoagulation To Remove Perfluoroalkyl And Polyfluoroalkyl Substances (Pfas) From Contaminated Water, Amy Yanagida
UCARE Research Products
Perfluoroalkyl and Polyfluoroalkyl substances (PFAS) are a family of manmade chemicals that are used to improve the quality of several commercial products by making them resistant to heat, oil, stains, grease and water. Unfortunately, the chemical properties that make PFAS useful from an industrial perspective also make them mobile and recalcitrant once released into the environment. We used electrocoagulation to run a direct current through contaminated water to generate a zinc floc to precipiate PFAS out of water.

Human consumption of freshwater is now approaching or surpassing the rate at which water sources are being naturally replenished in many regions, creating water shortage risks for people and ecosystems. Here we assess the impact of human water uses and their connection to water scarcity and ecological damage across the United States, identify primary causes of river dewatering and explore ways to ameliorate them. We find irrigation of cattle-feed crops to be the greatest consumer of river water in the western United States, implicating beef and dairy consumption as the leading driver of water shortages and fish imperilment in the ...
Recovering From Industrial Overshoot: Thermal Removal Of Atmospheric Co2, 2020 Embry-Riddle Aeronautical University
Recovering From Industrial Overshoot: Thermal Removal Of Atmospheric Co2, Ted Von Hippel, Sandra Boetcher, Matthew Traum, Farshid Azadian Ph.D., William Mackunis
Humanity will soon overshoot a safe level of atmospheric CO2, if it hasn't done so already. Countries, industries, and the global economy need to dramatically and quickly alter their behavior and technology to avoid this dangerous overshoot, yet this appears unlikely. Direct Air Capture of CO2 represents an insurance policy for society - a way of removing excess atmospheric CO2. I will present an approach to this problem based on thermal physics that cools cubic kilometers of air to extract CO2 as it sublimates. I propose a combination of an efficient heat exchanger, radiative cooling, and refrigeration, all at industrial ...

Fires are frequent in boreal forests affecting forest areas. The detection of forest disturbances and the monitoring of forest restoration are critical for forest management. Vegetation phenology information in remote sensing images may interfere with the monitoring of vegetation restoration, but little research has been done on this issue. Remote sensing and the geographic information system (GIS) have emerged as important tools in providing valuable information about vegetation phenology. Based on the MODIS and Landsat time-series images acquired from 2000 to 2018, this study uses the spatio-temporal data fusion method to construct reflectance images of vegetation with a relatively consistent ...
