Climate Change And Threatened Heritage: Archaeology's Burden, Barry R. Gordon

Theses and Dissertations

Climate change and archaeology are currently intertwined, as more and more archaeologists around the world must deal with the effects it causes on the sites they work on. Threatened cultural resource sites are being swept away at alarming rates, and excavation projects are becoming more and more like salvage digs.

Geochemical Fingerprints Of Glacially Eroded Bedrock From West Antarctica: Detrital Thermochronology, Radiogenic Isotope Systematics And Trace Element Geochemistry In Late Holocene Glacial-Marine Sediments, Patric Simões Pereira, Tina Van De Flierdt, Sidney R. Hemming, Samantha J. Hammond, Gerhard Kuhn, Stefanie A. Brachfeld, Cathleen Doherty, Claus-Dieter Hillenbrand

Department of Earth and Environmental Studies Faculty Scholarship and Creative Works

Geochemical provenance studies of glacial-marine sediments provide a powerful approach to describe subglacial geology, sediment transport pathways, and past ice sheet dynamics. The marine-based West Antarctic Ice Sheet (WAIS) is considered highly vulnerable to ocean warming and sea level rise that is likely to cause its rapid and irreversible retreat. Studies of its past response to climate change are hence essential for projecting its future behaviour. The application of radiogenic and trace element provenance studies for past ice sheet reconstructions requires surveying the geographic variability of geochemical compositions of glaciomarine sediments. In this study, we characterize the provenance of the …

Development Of The Wrf-Co2 4d-Var Assimilation System V1.0, Tao Zheng, Nancy H. F. French, Martin Baxter

Michigan Tech Publications, Part 1

Regional atmospheric CO2 inversions commonly use Lagrangian particle trajectory model simulations to calculate the required influence function, which quantifies the sensitivity of a receptor to flux sources. In this paper, an adjoint-based four-dimensional variational (4D-Var) assimilation system, WRF-CO2 4D-Var, is developed to provide an alternative approach. This system is developed based on the Weather Research and Forecasting (WRF) modeling system, including the system coupled to chemistry (WRF-Chem), with tangent linear and adjoint codes (WRFPLUS), and with data assimilation (WRFDA), all in version 3.6. In WRF-CO2 4D-Var, CO2 is modeled as a tracer and its feedback to meteorology is ignored. This …

A Socioeconomic Valuation Of Urban Wetland Ecosystems And Policy Recommendation For College Lake, Michael Dunmyer

Undergraduate Theses and Capstone Projects

Cityscapes in the United States are often viewed dichotomously in regards to natural environments. Preserved sites can be seen as an obstacle to urban development, and the concept of a functioning ecosystem within city limits is fictitious to many; we assume the two cannot coexist. Lynchburg, Virginia’s College Lake offers a unique case study for how urban ecosystems can not only subsist within cities but provide pivotal functions for them as well. With the potential for a dam-breaching storm event increasing in possibility with each passing year, concerns regarding the structural integrity of the College Lake dam in Lynchburg, Virginia …

All Or Nothing: An Investigation Of The Interconnection Between Social And Environmental Sustainability, Stacie F. Waites

Theses and Dissertations

Marketers have made attempts to understand the disconnect between consumers’ expressed desire to engage in sustainable behavior and their lack of adoption of sustainable products with ambiguous results. Because companies that engage in sustainability initiatives often focus on either environmental or social sustainability, the broader impact of sustainability is not always understood. When a company makes a promise to be socially sustainable, consumers may also think that the company is environmentally sustainable and vice versa. Moreover, consumer evaluations of companies that make promises to be either socially or environmentally sustainable may be different if the company later delivers a success …

(In)Visibility And Meaning In Food Labor: A Feminist Autoethnography, Kathryn Shedden

Masters Theses, 2010-2019

My graduate thesis project entitled “(In)visibility and Meaning in Food Labor: A Feminist Autoethnography” illuminates the gendered experiences of female food laborers and how women make meaning through their labor in this context. Gendered experiences do not stand apart from classed and raced identities, which I also reflexively analyze throughout this thesis. Women working within the food chain have been historically marginalized and made invisible, though they make up an increasingly significant portion of this workforce, a trend known as the “feminization of agriculture.” The discussion of the work that women do when discussing food in the academic literature also …

Agent-Based Modeling Of Pollen Competition, Katherine Bassett

Symposium on Research and Creative Expression (SORCE)

Non-random mating in Arabidopsis Thaliana is, at least in part, due to intense competition between pollen grains to fertilize the limited number of ovules. Previous studies have pinpointed some of the competition traits that make pollen more or less competitive. Using these competition traits, we will build an agent-based computer model with NetLogo that simulates the competition between two accessions of Arabidopsis Thaliana pollen. This 2D model will allow the user to adjust pollen traits and competition strategies for each of the two pollen accessions. Some of the factors being considered include pollen viability, pollen tube growth rate, nutrients provided …

Quantifying Factors That Influence Road Deicer Retention And Export In A Multi-Landuse Upstate New York Watershed, David Joseph Saba

Graduate Dissertations and Theses

Chloride contamination of streams and groundwater has become a prevalent issue throughout urbanizing areas in the last half century, particularly in northern latitudes where deicing salts are applied to roadways. This study determined how deicer impacted runoff disperses through sub-urban and urban areas on seasonal and multi-year scales. Chloride concentration changes were then modelled under varying pollutant loading scenarios through an integrated catchment model (INCA-Cl).

Six in-stream conductivity/stage/temperature sondes, recording at 15-minute intervals, were installed within the small (~9.6 km2) Fuler Hollow Creek multi-landuse watershed in Broome County NY and monitored over a 1-year period. Weekly grab samples were taken …

Seabird Distribution And Oil & Gas Potential Along The Northern Sea Route, Russia: An Arctic Marine Conservation Case Study, Meghan Kelly

Sustainability and Social Justice

Seabirds are indicator species for the marine environment. Their populations are simultaneously affected by access to food resources and anthropogenic pressures including direct disturbance and habitat degradation associated with industrial development (Parsons et al. 2007). Therefore, using seabird distribution as a policy-relevant indicator for the Arctic marine environment supports an ecosystem based management approach aimed at protecting sensitive habitats from increased offshore oil and gas development.

This research identifies seabird habitat in the Russian Arctic utilizing in situ seabird observations from the Northern Sea Route to create a species distribution model. The spatial location of these areas will be compared …

Ecological Sustainability Within California's Improved Forest Management Carbon Offsets Program, Cory Hertog

Sustainability and Social Justice

Forest Carbon offsets are being used as a climate change mitigation strategy in multiple programs around the world. But, are programs setup in a way that are ecologically sustainable? This paper reviews concepts pertinent to ecologically sustainable forest management and then examines if Improved Forest Management Carbon offset policies and projects within the California emissions trading scheme are setup in an ecologically sustainable manner. After a review of the Improved Forest Management Protocol and 31 project documents, it is apparent that policies and projects promote aspects of ecologically sustainable management. However, there is room for improvement when managing for natural …

Exploring The Potential Of Environmental Impact Investing For Sustainable Development: The Cases Of Dominion Energy And Tesla Motors, Christopher Dibble

Sustainability and Social Justice

The health of our planet and the existence of our species faces an uncertain future. Climate change is the single largest issue facing society today, as carbon-based fuel and combustion engines have driven development in nearly every industry. Public investment through securities markets have enabled corporations to extract coal and oil, build combustion engines, and distribute fuel commercially for over one hundred and fifty years. However, it is now widely accepted that if business-as-usual continues, carbon emissions will cause irreversible and devastating effects to the environment and humankind. International, national, local governments, companies, and general populations have taken steps to …

United In The Struggle: The Role Of Land Titles For Communities Of Internally Displaced Persons In El Salvador, Corie Welch

Sustainability and Social Justice

Multiple episodes of dispossession and displacement characterize the lives of landless rural and semi-rural families across El Salvador. The residents of 30 de Abril, a semi-rural community in El Salvador formed from displaced families, engaged in a five-year struggle to force the government to make good on its promise of land to the rural poor. Now, with legal titles in hand, residents continue to work together to seek additional services and resources for their community, proving their resilience in the face of displacement. Based upon the experience of 30 de Abril, this paper explores the trajectory of one community‟s struggle …

Degrowth Lessons From Cuba, Claire S. Bayler

Sustainability and Social Justice

Cuba is the global leader in practicing agroecology, but agroecology is just one component of a larger climate-ready socio-economic system. Degrowth economics address the need to constrain our total global metabolism to within biophysical limits, while allowing opportunity and resources for "underdeveloped" countries to rebuild themselves under new terms. Degrowth recognizes the role of overdeveloped countries in surpassing the ecological limits of our planet at the cost of wellbeing for billions of dispossessed people within and between countries. Cuba's circumstances during and following the Special Period exemplify both sides of the degrowth scenario, as well as demonstrating policy and grassroots …

Home On The Market Range: An Evaluation Of Cultural And Economic Barriers To Large-Scale Bison Farming, Skylar Peyton

All College Thesis Program, 2016-2019

Give me a home where the buffalo roam maybe a catchy tune from the 1800s, but it no longer represents the landscape of the American Midwest. As large-scale corporate farms invade the prairie with row crops and cattle yards, they are chasing away family practices as well as the antelope. Could bison, the original red meat, be a successful meat alternative? The argument that bison would be preferable to beef is based upon four premises: bison are better for the environment, healthier for human consumption, easier to manage, and similar in land needs. Based on these four premises, bison appears …

Speaking In Code, Mental Time Travel And Mind Reading: An Exploration Of The Study Of Animal Intelligence, Drew S. Perlmutter

Standard Theses

Many humans believe they are separate from nature based on “unique” characteristics. For many centuries, our advanced tool use was believed to separate us from other animals. However, discoveries made by Jane Goodall in the 1960’s demonstrated that humans are not unique for this capacity.1 In light of these discoveries, the definition of human was altered to suggest that our intelligence sets us apart from other animals. This definition has been used in order to justify our exploitation of other animals by suggesting that we are unique, and therefore, superior due to this “unique” intelligence. However, humans are not alone …

Distinguishing Harms To Derive Commitments: Karen Warren And Aldo Leopold On Ecofeminism And Domination, Eileen A. O'Shea

Standard Theses

This paper explores Karen Warren's formulation of an Ecofeminist argument, and aims to restructure it in a way that does not equate the impacts of domination on women with the impacts of domination on the natural world. With supplemental elements of Aldo Leopold's "Land Ethic" arguments, I hope to provide a reformulation of Warren's argument in which the dominator is still committed to dismantling these twin dominations. I posit that this commitment may be derived from the harm the process of dominating inflicts on the dominator's perfectionist value and prudential value, an element which remains consistent in both dominations and …
