Vulnerability Assessment Of The Gulf Of Maine Eastern Oyster Aquaculture Industry To The Projected Impacts Of Ocean And Coastal Acidification, Julia L. Neumann 2022 University of San Francisco

Vulnerability Assessment Of The Gulf Of Maine Eastern Oyster Aquaculture Industry To The Projected Impacts Of Ocean And Coastal Acidification, Julia L. Neumann

Master's Projects and Capstones

Ocean acidification is an emerging global environmental issue with known impacts on calcifying marine and estuarine organisms, including oysters. Anthropogenic climate change increases ocean uptake of atmospheric carbon dioxide, which decreases seawater pH and the availability of crucial calcium carbonate minerals, namely calcite and aragonite. Acidification poses a major threat to the Eastern oyster aquaculture industry in the Gulf of Maine (GOM), which is highly susceptible to acidification and highly economically dependent on the industry’s economic contributions. In this report, I evaluated overall vulnerability of the GOM Eastern oyster aquaculture industry by assessing ecological exposure, social sensitivity, and adaptive ...


Changes In Heat Metrics Following A Major Hurricane And Implications On Heat Stress, Cade Reesman 2022 Louisiana State University and Agricultural and Mechanical College

Changes In Heat Metrics Following A Major Hurricane And Implications On Heat Stress, Cade Reesman

LSU Master's Theses

Tropical cyclones modify surface-atmosphere interactions in several ways, including the destruction of patches of tree canopy, increasing the direct and diffuse (shortwave) radiation reaching the surface. This addition of radiation at the surface impacts the sensible, latent, and substrate heat (energy) fluxes, generating heat anomalies along the hurricane’s track, which, among other effects, contributes to the higher post-hurricane surface air temperatures. This study consists of a case study on Hurricane Laura (2020) to examine hurricane defoliation impacts on heat stress metrics. Normalized difference vegetation index (NDVI) data from NASA’s Moderate Resolution Imaging Spectroradiometer (MODIS) identified the spatial extent ...


Murphy Scale: A Locational Equivalent Intensity Scale For Hazard Events, Yi Victor Wang, Antonia Sebastian 2022 Chapman University

Murphy Scale: A Locational Equivalent Intensity Scale For Hazard Events, Yi Victor Wang, Antonia Sebastian

Institute for ECHO Articles and Research

Empirical cross-hazard analysis and prediction of disaster vulnerability, resilience, and risk requires a common metric of hazard strengths across hazard types. In this paper, the authors propose an equivalent intensity scale for cross-hazard evaluation of hazard strengths of events for entire durations at locations. The proposed scale is called the Murphy Scale, after Professor Colleen Murphy. A systematic review and typology of hazard strength metrics is presented to facilitate the delineation of the defining dimensions of the proposed scale. An empirical methodology is introduced to derive equivalent intensities of hazard events on a Murphy Scale. Using historical data on impacts ...

The Effects Of Dissolved And Suspended Solids On Freshwater Meiofauna, Jessica Cline 2022 University of Tennessee at Chattanooga

The Effects Of Dissolved And Suspended Solids On Freshwater Meiofauna, Jessica Cline

Honors Theses

Meiofauna include small-sized animals (< 1mm) distributed in all aquatic ecosystems on Earth, where they play fundamental trophic and ecological roles. The biodiversity of marine meiofauna and its links with anthropogenic activities is routinely investigated, however, freshwater communities are less known. This is particularly true for the Southeastern United States, which is greatly investigated and elected a hotspot of biodiversity for larger species but very little is known about the meiofauna. The purpose of this research is to reveal the biodiversity of meiofauna from the Tennessee River and test for potential correlations with anthropogenic activities. As a proxy for pollution, dissolved and suspended solids were considered in this study. The research hypothesis is that meiofaunal biodiversity would be affected by possible changes of dissolved and suspended solids in the water column. Possible mechanisms causing biodiversity shifts could be ascribed to osmotic stresses of animals to cope with variation in dissolved solids or, more indirectly, because different sunlight penetration caused by suspended solids would affect primary production. To test the hypothesis, water samples were collected from nine stations located along the Tennessee River in Hamilton County. Each station was visited three times, and, during each visit, environmental parameters (including dissolved and suspended solids) were measured. Meiofauna biodiversity (estimated as richness, community composition, and phylogenetic diversity) was revealed using a metagenomic approach. Statistical analyses were applied to test for possible correlations between the biodiversity estimates and the measured environmental parameters. Results show a high biodiversity of meiofauna with more than 200 amplicon-sequence variants distributed across 10 metazoan phyla. Environmental conditions are highly variable among stations and statistical analyses show that while both dissolved solids (TDS) and turbidity (suspended solids, NTU) did not significantly affect meiofauna biodiversity in the collected samples, various other water, and sediment metrics were found to be significant predictors of meiofauna biodiversity. In conclusion, the results of this project not only reveal for the first time the meiofauna biodiversity from the Tennessee River, but also suggest that meiofauna could be used as bioindicators for several anthropogenic activities in freshwater ecosystems.


Multi-Criteria Evaluation Model For Classifying Marginal Cropland In Nebraska Using Historical Crop Yield And Biophysical Characteristics, Andrew Laws 2022 University of Nebraska-Lincoln

Multi-Criteria Evaluation Model For Classifying Marginal Cropland In Nebraska Using Historical Crop Yield And Biophysical Characteristics, Andrew Laws

Dissertations & Theses in Natural Resources

Marginal cropland is suboptimal due to historically low and variable productivity and limiting biophysical characteristics. To support future agricultural management and policy decisions in Nebraska, U.S.A, it is important to understand where cropland is marginal for its two most economically important crops: corn (Zea mays) and soybean (Glycine max). As corn and soybean are frequently planted in a crop rotation, it is important to consider if there is a relationship with cropland marginality. Based on the current literature, there exists a need for a flexible yet robust methodology for identifying marginal land at different scales, which takes advantage ...

We tracked census tract level population change along California's wild land-urban interface (WUI) during the past decade (2010-2019), an ecological sensitive region transitioning from developed land to wilderness. Our results from Mann-Kendall analysis, a method employed for monotonic trend detection showed that about one-third (29.1%) of census tracts in California’s WUI have seen a significant population increase from 2010 to 2019, affecting 12.7% population in California.

The population increase along WUI is largely driven by the sixteen counties in the San Francisco Bay Area (10) and Southern California (6). We also found that higher proportion of ...

Cladding By Another Name: A Comparative Analysis Of The Environmental And Economic Costs Of Traditional Wood Clapboards, Composite Fiber-Cement Siding, And Vinyl Siding, Nicole Larochelle

All Theses

Using the tools provides by the scientific community, namely the products of lifecycle cost assessments (LCA) – which are synthesized in environmental product declarations (EPD) – and life cycle cost assessments (LCCA), the overall environmental and economic impacts of historic, traditional, and simulated materials are established and compared. This informs the historic preservation community of the quantifiable sustainability of historic materials in relation to alternatives. Through these two different methods of environmental and economic life cycle costing, this research demonstrates that retaining in-situ siding incurs the least impact on the environment and is the second most economic option. While the installation of ...


Changes In Western U.S. Streamflow Extremes Under Climate Change, Rama Bedri 2022 Chapman University

Changes In Western U.S. Streamflow Extremes Under Climate Change, Rama Bedri

Student Scholar Symposium Abstracts and Posters

We are analyzing streamflow extremes in Western U.S. rivers due to climate change. Global warming causes natural disasters to reach extreme points and affects river volumes, snowfall, and precipitation amounts. We analyze the data for 17 stations in the Colorado River Basin, whose rivers provide Southern California’s drinking water supply. Disruptions in streamflow due to climate change affect the region’s water availability and make it difficult to predict future trends. We compared historical streamflow data to eight possible climate scenarios. The different scenarios are Warm Dry, Cool Wet, Average, and Other at emission levels of RCP 4 ...

Understanding the dynamics of peatland methane (CH4) emissions and quantifying sources of uncertainty in estimating peatland CH4 emissions are critical for mitigating climate change. The relative contributions of CH4 emission pathways through ebullition, plant-mediated transport, and diffusion, together with their different transport rates and vulnerability to oxidation, determine the quantity of CH4 to be oxidized before leaving the soil. Notwithstanding their importance, the relative contributions of the emission pathways are highly uncertain. In particular, the ebullition process is more uncertain and can lead to large uncertainties in modeled CH4 emissions. To improve model simulations of CH4 emission and its pathways ...
