Effects Of El Niño On Ecological Growth Along Californian And Peruvian Coasts, Alexandra Sidun

Student Scholar Symposium Abstracts and Posters

This study examines the mechanisms of El Niño to further understand the ecological effects it may have along the Californian and Peruvian coasts. El Niño is the warm phase of the El Niño Southern Oscillation (ENSO). While it is a global phenomenon, these two locations were investigated for their nearly equal and opposite conditions during storm months. California, which is in an extreme state of drought, often receives heavy rainfall during El Niño and understanding its potential effects is crucial. El Niño causes upwellings along the CA coast and warm water from the region displaces the normally cool waters along …

Assessing Water Quality In The Gulf Of Mexico Using Remote Sensing Data., Alliyah Thomas

Student Scholar Symposium Abstracts and Posters

Hypoxia, or oxygen depletion, is a process that occurs in conjunction with eutrophication. In hypoxic conditions the dissolved oxygen levels in the water column sink to unlivable conditions for the marine organisms causing them to flee or die. Despite efforts of improvement, the annual summer Gulf of Mexico dead zone continues to be a serious threat to aquatic ecosystems. The 2012 smaller than usual dead zone was a false indicator of future improvement. The 2012 dead zone decrease was connected to the drought and inability of large amounts of runoff to flow into the gulf. Water quality analysis was done …

Urban Scale Modeling Of Atmospheric Carbon Dioxide And Validation Of Emission Inventories, James E. Powell, Christopher L. Butenhoff, Andrew L. Rice

Student Research Symposium

There exists a pressing need for high resolution emissions inventories for cities. For greenhouse gases, cities and regions need a careful analysis of their carbon footprint to design effective policies to control and mitigate emissions. High resolution emissions inventories can be used in conjunction with meteorology models and atmospheric measurements to place top-down constraints on emissions. High resolution emissions inventories for criteria pollutants like NO_x, CO, and O₃ enable urban-scale air pollution modeling down to the neighborhood level. For example, the Vulcan project estimates CO₂ using county-scale vehicle miles traveled (VMT) from the National Mobile Inventory …

The Human And Environmental Effects Of Cbrn Weapons, Brendan M. Doran

Student Theses 2015-Present

Since the first use of modern weapons of mass destruction during the First World War, the World has lived in fear of these horrifying instruments of death. Gripped by this fear, countries around the world have continued to research, develop, and test these weapons in the spirit of mutually assured destruction. Over the years, science and warfare have continually refined their methods of human extermination, bringing forth some of the most terrifyingly effective weapon systems ever devised. However, the testing and use of these weapons is often a step into the unknown. The repercussions of deploying these weapons are sometimes …

Geochemical Analysis Of Surface Materials Surrounding The Bautsch-Gray Mine Superfund Site Near Galena, Illinois, Ryan Plath

Geology: Student Scholarship & Creative Works

The Bautsch-Gray zinc and lead mine, near Galena, IL, was in operation from the early 1900s until closing in 1975. The mine’s tailings pile has documented elevated lead and zinc concentrations in the surface materials surrounding the site. Numerous floods have caused contaminated sediment to migrate off the mine tailings pile, across Blackjack Road and into an outwash basin, and towards Smallpox Creek. Since this site was designated an EPA priority list Superfund site in 2010, the EPA has conducted numerous remediation efforts. This study attempts to develop a better understanding of the contamination within the soils of the outwash …

Combining And Aggregating Environmental Data For Status And Trend Assessments: Challenges And Approaches, Kathleen G. Maas-Hebner, Michael Harte, Nancy Molina, Robert M. Hughes, Carl B. Schreck, J. Alan Yeakley

Environmental Science and Management Faculty Publications and Presentations

Increasingly, natural resource management agencies and nongovernmental organizations are sharing monitoring data across geographic and jurisdictional boundaries. Doing so improves their abilities to assess local-, regional-, and landscape-level environmental conditions, particularly status and trends, and to improve their ability to make short-and long-term management decisions. Status monitoring assesses the current condition of a population or environmental condition across an area. Monitoring for trends aims at monitoring changes in populations or environmental condition through time. We wrote this paper to inform agency and nongovernmental organization managers, analysts, and consultants regarding the kinds of environmental data that can be combined with suitable …

Using Kriging, Cokriging, And Gis To Visualize Fe And Mn In Groundwater, Crystal Johnson

Electronic Theses and Dissertations

For aesthetic, economic, and health-related reasons, allowable concentrations of iron (Fe) and manganese (Mn) found present in drinking water are 0.3 mg/L and 0.05 mg/L, respectively. Water samples taken from private drinking wells in the rural communities within Buncombe County, North Carolina contain amounts of these metals in concentrations higher than the suggested limits. This study focused on bedrock geology, elevation, saprolite thickness, and well depth to determine factors affecting Fe and Mn. Using ArcGIS 10.2, spatial trends in Fe and Mn concentrations ranges were visualized, and estimates of the metal concentrations were interpolated to unmonitored areas. Results from this …

Local Response To Climate Change: A Case Study Approach, Nora Gimpel

Honors Theses

The scientific consensus on the causes and consequences of climate change is clear and experts continue to strongly recommend immediate mitigation and adaptation responses (IPCC, 2014). Responses to climate change are occurring at the international, national, and subnational level, but adaptation to climate change is also highly local. Local communities across the world are organizing groups and institutions to determine their best responses for local mitigation and adaptation actions. This study analyzed the formal local community organization, the Kalamazoo Climate Change Coalition (KCCC), and its structured activities in order to evaluate how Kalamazoo has responded to climate change. Methodology for …

Developmental Toxicity Of Tetrakis (Hydromethyl) Phosphonium Chloride (Thpc) In Zebrafish (Danio Rerio) Embryos, Lan L. Nguyen

Honors College Theses

Tetrakis (hydromethyl) phosphonium chloride (THPC) is a tetrakis (hydromethyl) phosphonium salt commonly used by the textile industry and is polymerized onto cotton fabrics to provide a flame-retardant finish. Traces of THPC were found in the Ogeechee River, a 294 mile-long black river in Georgia, and could have been a toxin contributing to the mass killing of aquatic animals in May 2011. THPC has been known to be carcinogenic and cause other systemic toxicity in various mammalian animals. However given that the chemical is mostly discharged in natural waters, the environmental impact of the discharge on water quality and there by …

Uncertainty In Simulating Gross Primary Production Of Cropland Ecosystem From Satellite-Based Models, Wenping Yuan, Wenwen Cai, Anthony L. Nguy-Robertson, Huajun Fang, Andrew E. Suyker, Yang Chen, Wenjie Dong, Shuguang Liu, Haicheng Zhang

School of Natural Resources: Faculty Publications

Accurate estimates of gross primary production (GPP) for croplands are needed to assess carbon cycle and crop yield. Satellite-based models have been developed to monitor spatial and temporal GPP patterns. However, there are still large uncertainties in estimating cropland GPP. This study compares three light use efficiency (LUE) models (MODIS-GPP, EC-LUE, and VPM) with eddy-covariance measurements at three adjacent AmeriFlux crop sites located near Mead, Nebraska, USA. These sites have different croprotation systems (continuous maize vs. maize and soybean rotated annually) and water management practices (irrigation vs. rainfed). The results reveal several major uncertainties in estimating GPP which need to …

The Restoration Process: Lessons From A Community-Based Conservation Initiative In Tunkhel, Mongolia, John Wendt

Independent Study Project (ISP) Collection

As policy makers transition away from central planning, Mongolia’s natural resource professionals are challenged with cultivating community support for stewardship in a time of escalating ecological disturbance. Nutag Action Research Partners has partnered with community members and government officials in Tunkhel, a small village in north-central Mongolia, to develop local resource management capacity and jointly draft a Conservation Plan for a commonly grazed riparian pasture. This study is a preliminary assessment of the ecological and social factors influencing project implementation. Information was collected using a variety of qualitative methods including meeting observation, surveys, interviews, photographs, and a review of previous …

A Feasibility Study Of Using Unmanned Aerial Vehicles To Survey Avian Abundance By Using Audio Recording, Janine M. Barr, Andrew M. Wilson

Student Publications

Roadside counts are commonly used to assess songbird abundance, but they result in oversampling habitat edges and underrepresenting core habitats, areas of steep terrain, and wetlands. Accessing off-road habitats can be logistical challenging and time-consuming, resulting in low survey efficiency. Aerial ecological surveys, using unmanned aerial vehicles (UAVs, or drones) have already proven to be valuable in wildlife monitoring. Previous studies have used photography or videography to provide permanent documentation of wildlife surveys through low altitude aerial imagery. A significant advantage of UAVs over manned aircraft is their greater safety and lower costs. We propose that UAVs can also be …
