Despite the importance of high-latitude surface energy budgets (SEBs) for land-climate interactions in the rapidly changing Arctic, uncertainties in their prediction persist. Here, we harmonize SEB observations across a network of vegetated and glaciated sites at circumpolar scale (1994–2021). Our variance-partitioning analysis identifies vegetation type as an important predictor for SEB-components during Arctic summer (June-August), compared to other SEB-drivers including climate, latitude and permafrost characteristics. Differences among vegetation types can be of similar magnitude as between vegetation and glacier surfaces and are especially high for summer sensible and latent heat fluxes. The timing of SEB-flux summer-regimes (when daily mean values …

Arctic warming is affecting snow cover and soil hydrology, with consequences for carbon sequestration in tundra ecosystems. The scarcity of observations in the Arctic has limited our understanding of the impact of covarying environmental drivers on the carbon balance of tundra ecosystems. In this study, we address some of these uncertainties through a novel record of 119 site-years of summer data from eddy covariance towers representing dominant tundra vegetation types located on continuous permafrost in the Arctic. Here we found that earlier snowmelt was associated with more tundra net CO2 sequestration and higher gross primary productivity (GPP) only in June …

What Technologies And Barriers Are Present In Sustainable Heating And Cooling, Mason D. Nibbe

Environmental Studies Student Work

Sustainable heating and cooling practices can save homeowners money and reduce their carbon emissions. In the cold upper Midwest, Minnesota specifically, there are ways houses can be more efficient in terms of heating. The most efficient and practical are heat pumps systems, passive solar designs, and proper insulation of the building. This study is targeted at both existing buildings and the construction of new buildings. This project focuses on what sustainable heating and cooling practices, technologies, and barriers are present in the heating, ventilation, and air-conditioning (HVAC) industry. I find that using any sustainable solution is helpful, but multiple solutions …

Tomorrow’S Stewards: Engaging Youth With Environmental Volunteerism, Miriam Nelson

Environmental Studies Student Work

Environmental volunteers are of great value to their host organizations, the environment, the economy, and civil society. The Friends of Acadia (FOA) Drop-In Stewardship Volunteer Program hosts volunteers who complete an assortment of tasks in Acadia National Park. However, this program has no regular youth volunteers. Engaging youth volunteers is critical for program effectiveness, civic engagement, generativity, and increasing personal development. Drawing on survey data collected from FOA volunteers and College of the Atlantic students, this paper analyzes volunteer motivations and interests, and barriers to participation. I conclude with suggestions for how FOA can recruit more youth volunteers.

Oak Savanna Restoration And Climate Change Mitigation Through Silvopasture In Minnesota, James Siems

Environmental Studies Student Work

Reducing emissions of world food systems will be critical to combatting climate change. Silvopasture systems, which integrate managed forests with pastureland, have been shown to be a more sustainable alternative to traditional livestock production and have the ancillary benefit of diversifying the sources of income for farmers. Silvopasture may also have the capacity to serve as a mechanism for ecological restoration. This paper combines existing literature with an interview of a farmer who is engaging in silvopasture to evaluate the potential of silvopasture as means to restore Minnesota’s disappearing oak savanna ecosystem, while improving the sustainability of food production within …

Flood Hazard And Risk Analyses In The Republic Of Panama: A Case Study From The Juan Diaz River Watershed In Panama City, Virgilio De Jesus Quintero

Graduate Theses and Dissertations

Flooding is the natural hazard with most occurrences in Panama. Its frequency and magnitude have increased over the years. This dissertation analyzes Panama’s flood activity in order to better understand flood hazards, the current evolution of Panamanian perceptions of flood risk, and the incorporation of indigenous knowledge used to mitigate flood hazards. The first chapter developed a baseline of past and current flood inventory in Panama, which required the use of flood historical data, thematic cartography, and Geographic Information Science (GIS). This chapter shows Panama has experienced floods in varying degrees. Through the spatial and temporal distribution of floods from …

Ocean acidification (OA) has resulted in global-scale changes in ocean chemistry, which can disturb marine organisms and ecosystems. Despite its extensively populated coastline, many marine-dependent communities, and valuable economies, the Gulf of Mexico (GOM) remains a relatively understudied region with respect to acidification. In general, the warm waters of the GOM are better buffered from acidification compared to higher latitude seas, yet long-term acidification has been documented in several GOM regions. OA within the GOM is recognized as spatially variable, particularly within the coastal zone where numerous physical and biogeochemical processes contribute to carbonate chemistry dynamics. The historical progression of …

Understanding The Barriers To Carbon Farming On Private Lands, Harrison Naftel

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Climate change caused by manmade greenhouse gas emissions is one of the most important challenges facing society today. Through effective management for carbon sequestration private agricultural lands could become an important part of the solution to this problem. This paper explores the many different methods that farmers, ranchers, and landowners could use to implement sequestration on their land and examines the barriers to further participation in these projects by reviewing the challenges in the world’s current carbon offset markets and offering possible solutions.

AfriArch is an archaeological and paleoenvironmental data community designed to integrate datasets related to human-environmental interactions in Holocene Africa. Here we present a dataset of bioarchaeological stable isotope (C/N/O) and radiocarbon measurements from African archaeological sites spanning the Holocene. Modern measurements, when reported together with archaeological data in original publications, are also included. The dataset consists of 5568 entries and covers the entirety of Africa, though most isotopic research has been concentrated in southern Africa. The AfriArch isotopic dataset can be used in paleodietary, paleodemography, paleoclimatic, and paleoenvironmental studies. It can also be employed to highlight data gaps across space …

Bridgeport Poised To Be Site Of Nebraska’S Next Environmental Catastrophe, Kjersten Hyberger

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

Bridgeport Ethanol LLC is Nebraska’s first ethanol plant to be under contract for Carbon Capture and Sequestration (CCS) in the state. Despite ongoing safety concerns by federal regulators and organized opposition from affected landowners, Carbon America is pushing forward with their plans to have the Bridgeport CCS facility operational by 2024. At a time when Nebraska has barely begun cleanup of the AltEn disaster in Mead, and the agrochemical contamination levels in our soil and groundwater are at historic levels, we cannot carelessly add one more pollutant to the mix.

In May of this year the Legislature passed the Nebraska …

Low total energy expenditure (TEE, MJ/d) has been a hypothesized risk factor for weight gain, but repeatability of TEE, a critical variable in longitudinal studies of energy balance, is understudied. We examine repeated doubly labeled water (DLW) measurements of TEE in 348 adults and 47 children from the IAEA DLW Database (mean ± SD time interval: 1.9 ± 2.9 y) to assess repeatability of TEE, and to examine if TEE adjusted for age, sex, fat-free mass, and fat mass is associated with changes in weight or body composition. Here, we report that repeatability of TEE is high for adults, but …

Submarine groundwater discharge is increasingly recognized as an important component of the oceanic geochemical budget, but knowledge of the distribution of this phenomenon is limited. To date, reports of meteoric inputs to marine sediments are typically limited to shallow shelf and coastal environments, whereas contributions of freshwater along deeper sections of tectonically active margins have generally been attributed to silicate diagenesis, mineral dehydration, or methane hydrate dissociation. Here, using geochemical fingerprinting of pore water data from Site J1003 recovered from the Chilean Margin during D/V JOIDES Resolution Expedition 379 T, we show that substantial offshore freshening reflects deep and focused …

Practicing Re-Enlightenment : Technology Revisited In The Age Of Climate Change, Gyuri Kang

Legacy Theses & Dissertations (2009 - 2024)

In the age of climate change, the Indian writer Amitav Ghosh asks whether humanity is prepared for the unthinkable nature of climate events. The Earth’s climate is changing faster than humans can expect and adapt. Ghosh warns that modern people are too deranged to imagine in what forms of changes are approaching. His term, derangement, suggests that humans are no longer able to imagine the future world shaped by climate change. The signals of the unexpectable realities of climate change, however, may be hidden in existing knowledge. Here, technology can help us access this hidden knowledge through its ability to …

Impact Of Eocene-Oligocene Antarctic Glaciation On The Paleoceanography Of The Weddell Sea, Victoria Hojnacki, Allison Lepp, Josie Horowitz Castaldo, Abbey States, Xiaona Li, Sandra Passchier

Department of Earth and Environmental Studies Faculty Scholarship and Creative Works

The Eocene-Oligocene Transition (EOT) at ∼34 Ma marked a climatic shift from greenhouse to icehouse conditions, toward long-lasting lower global temperatures and a continental ice sheet in the Antarctic. We report on sedimentological and inorganic geochemical results across the EOT at Ocean Drilling Program (ODP) Site 696 in the Weddell Sea, within the Antarctic limb of the Atlantic circulation. The geochemical composition of detrital, authigenic and biogenic marine sediment components, and sortable silt proxies demonstrate the impact of ice growth on high latitude water masses. Sortable silt grain size and Zr/Rb ratios attest to a period of vigorous circulation at …

Characterizing The Traditional Fisheries Of Salary, Madagascar Within A Marine Protected Area, Caitlin R. Shanahan

Master's Theses and Capstones

Protected Areas are a tool used by the International Union Conservation of Nature (IUCN) to limit changes to and preserve important and fragile ecosystems, allowing varying permissible activities within their boundaries. Locally Managed Marine Areas (LMMAs) are a similar tool, but with a higher emphasis of community engagement in the planning process with community-based ownership and regulation. In Madagascar, there are both IUCN Marine Protected Areas (MPAs) and LMMAs established to help conserve their high marine biodiversity and healthy reef systems. While the LMMAs and some of the MPAs permit sustainable fishing, it is unknown if the traditional, small-scale fisheries …

Authigenic Clay Mineral Evidence For Restricted, Evaporitic Conditions During The Emergence Of The Ediacaran Doushantuo Biota, Shujun Han, Stefan C. Lӧhr, April N. Abbott, Andre Baldermann, Martin Voigt, Bingsong Yu

Marine Science

The Ediacaran Period witnessed major environmental change and an expansion of eukaryotic life following the Marinoan glaciation. The Doushantuo Formation of south China has furnished much of our understanding of Earth System and biosphere evolution during this period, but its depositional setting–marine or non-marine–is still debated. Here we conduct mineralogical, petrographic and geochemical analyses of samples from the lower Doushantuo Formation in order to determine the origin of saponite clay minerals which are abundant in this interval. We find that the morphology and distribution of the saponite clays suggest they are of pre-compaction, authigenic origin. We infer that the lower …

Anticipating The Impacts Of The Social, Political, And Biophysical Landscape On Long-Term Connectivity For Reintroduced Plains Bison, Jamie Ann Faselt

Boise State University Theses and Dissertations

Intense anthropogenic pressures on the natural environment have created the need for implementing strategies that promote or restore habitat connectivity. The ability for animals to move between habitat patches allows animals to find mates, access resources, and shift their range in response to the changing climate and ensures that ecological and evolutionary processes persist. Connectivity conservation typically focuses on biophysical barriers to animal movement, but for many species reintroductions, establishing and maintaining connectivity often requires overcoming both ecological and socio-political barriers. Despite the need to navigate complex socio-political landscapes to implement connectivity conservation plans, datasets depicting those conditions are rarely …

Esg Is Fiduciary Duty, Katherine Held

Honors Theses

This Thesis defends the validity of ESG Investing (Environmental, Social, Governance Investing) as an advisor’s fiduciary responsibility. The financial industry is increasingly including ESG considerations when calculating the intrinsic value of a stock. In opposition to this valuation trend, nineteen state attorney generals (Nineteen) have attacked ESG, challenging its legality by claiming that it violates state and federal law and the fiduciary responsibilities that hold investment advisors accountable to their clients. After identifying key elements of fiduciary responsibility that are being ignored by the Nineteen’s position, several key and relevant United States statutes are reviewed and applied to their argument. …

Transcriptomic Signal Of Reproductive Modes And Early Speciation In Daphnia Pulex-Pulicaria System, Trung Viet Huynh

Biology Dissertations - Archive

Daphnia have been gaining recognition as a key model system for studies of evolution, ecology, toxicology, and more recently genomics. The defining characteristic of this particular model system is its phenotypic plasticity and its responsiveness to environmental cues. At the same time, the advent of RNA sequencing technology has helped researchers gain new insights on the plasticity of gene expression and its role linking environmental cues with the physiological response mounted by the organism. Although many RNA-seq studies have been conducted in Daphnia, surprisingly no one has recorded the gene expression profile of one of Daphnia’s most famous phenotypic plastic …

The Dream Of Property: Law And Environment In William T. Vollmann’S Dying Grass And Leslie Marmon Silko’S Almanac Of The Dead, Ted Hamilton

Faculty Journal Articles

This article describes how the law inflects the narration of environmental conflict in William T. Vollmann’s Dying Grass (2015) and Leslie Marmon Silko’s Almanac of the Dead (1991). By focusing on the legal common sense of settler colonialism—its emphasis on private property in land and its subjugation of Indigenous peoples to the guardianship of the state—the article explores the ways in which Vollmann’s and Silko’s novels present counternarratives to the law’s story of justified conquest. Combining a law and literature approach with ecocriticism, this article highlights the importance of the legal imagination in defining human-land relations in the United States. …

Spatiotemporal Change Detection Of The Alpine Meadows At Holcomb Valley, San Bernardino Mountain National Forest, Using Gis And Remote Sensing Techniques, Rama Ewing

Electronic Theses, Projects, and Dissertations

Holcomb Valley, with a general elevation between 2200-2257m, is in the Northeast of Big Bear Lake in the San Bernardino Mountains. Holcomb Valley is covered by Alpine meadows, unlike most mountain landscapes, which are rarely found in Mediterranean climates such as California. The cultural-environmental history of the San Bernardino Mountains in the past century speaks of intense anthropogenic activities such as timbering, grazing, gold mining, and extreme climate changes (i.e., drought, fires, floods). A study is conducted to identify and calculate the changes in the Alpine meadows at Holcomb Valley. The climatical data has been acquired to compute and visualize …
