Micro-Spi Sediment Profile Imaging Micro-Inspector, Andrew P. Corvin, Caleb T. Davies, Matt R. Ferrari 2017 California Polytechnic State University, San Luis Obispo

Micro-Spi Sediment Profile Imaging Micro-Inspector, Andrew P. Corvin, Caleb T. Davies, Matt R. Ferrari

Mechanical Engineering

This project was proposed by Dr. Brian Paavo through a desire to more easily study the benthic sediment layers of the ocean. To do so, he asked us to build a simple and compact machine for use in sediment profile imagery (SPI). Although devices like this already exist, they are all large scale devices that require a ship with a crane to deploy, which is expensive and time consuming. Instead, he desired a “micro” SPI, which is capable of being deployed from a small vessel that can easily navigate shallow waters. Our interpretation of these requirements was as follows: a …


Evaluation Of A Filtration Sorbent For Remediation Of Arsenic In Groundwater, Clement Do 2017 California State University - San Bernardino

Evaluation Of A Filtration Sorbent For Remediation Of Arsenic In Groundwater, Clement Do

Electronic Theses, Projects, and Dissertations

A commercially available product, PURA PhosLock, was identified and evaluated for use as a sorbent to remove dissolved arsenic (As) from drinking water. Although marketed as a product to remove phosphate in aquaria, it is composed of iron oxide hydroxide (i.e., FeO(OH)), which is also known to adsorb dissolved As species from water. Arsenic was measured using standard methods and Graphite Furnace Atomic Absorption Spectroscopy. A first rough filtration test was performed to see if the PhosLock adsorbed As well. About 50 g of PhosLock was used to filter 10 L of tap water containing 100 ppb As. No detectable …

Stable Isotopes In Atmospheric Water Vapour From Mauna Loa, Hawaii, 2016-2017, Joseph Galewsky

Earth and Planetary Sciences Faculty and Staff Publications

The isotopic composition of atmospheric water vapor (1H216O, H218O, and 1H2H16O) was continuously measured at the National Oceanic and Atmospheric Administration (NOAA) Mauna Loa Observatory (MLO) from April 8, 2016 through March 13, 2017 using Off-Axis Integrated Cavity Output Spectroscopy (OA-ICOS). The dataset has been carefully corrected for humidity-dependent biases and calibrated against the international VSMOW-SLAP scale to provide a precise, continuous, nearly yearlong dataset from a dynamic subtropical setting. The measurements are provided with 15-minute and 6-hourly resolution.


Embodied Carbon: A Framework For Prioritizing And Reducing Emissions In The Building Industry, Natalie C. Wheating 2017 The University of San Francisco

Embodied Carbon: A Framework For Prioritizing And Reducing Emissions In The Building Industry, Natalie C. Wheating

Master's Projects and Capstones

Global climate change is one of the most impactful environmental issues in modern times, and the construction industry is known to be one of the largest contributors to carbon emissions—one of the key causes of climate change. Embodied carbon emissions of buildings are an often overlooked, but significant, influencer of a building’s overall carbon footprint. This gives rise to the need for improved life cycle analysis of buildings and identification of opportunities to reduce the total carbon footprint of a building throughout its life cycle. This paper analyzes the current state of the building industry that limits the consideration of …


The Relationship Between Wildfire Dynamics And Soil Carbon In Boreal Forests Of Alaska: Forest Management For Emissions Reduction In A Changing Climate, James D. Heaster 2017 University of San Francisco

The Relationship Between Wildfire Dynamics And Soil Carbon In Boreal Forests Of Alaska: Forest Management For Emissions Reduction In A Changing Climate, James D. Heaster

Master's Projects and Capstones

The boreal region of Alaska has vast forests spanning hundreds of thousands of square kilometers in the central portion of the state that is prone to large stand replacing summer wildfires. The region stores considerable quantities of terrestrial carbon sequestered in soil horizons down to 1 meter in depth that are strongly influenced by a combination of climate change, permafrost dynamics, vegetative composition, and fire regimes. Data and literature establish that the boreal region of Alaska (and the rest of the Arctic) has been steadily warming at a rate nearly double that of lower latitudes. This warming has resulted in …


California Public Electric Vehicle Charging Stations’ Accessibility To Amenities: A Gis Network Analysis Approach, Jeremy Yun Li Chen 2017 University of San Francisco

California Public Electric Vehicle Charging Stations’ Accessibility To Amenities: A Gis Network Analysis Approach, Jeremy Yun Li Chen

Master's Projects and Capstones

In California, the number of electric vehicles (EVs) on the roads has been increasing over the past several years. As EVs continue to grow, additional electric vehicle charging stations (EVCSs) will be needed for EV drivers to utilize. However, before implementing EVCSs in the public, there are various criteria that need to be considered. One of these criteria is public EVCSs’ accessibility to amenities. When people are charging their EVs that require a significant amount of waiting time, having amenities nearby will provide them with the option to spend their time efficiently on worthwhile activities. To understand the accessibility of …


Evaluating The Impacts Of Farmers’ Behaviors On A Hypothetical Agricultural Water Market Based On Double Auction, Erhu Du, Ximing Cai, Barbara Minsker 2017 University of Illinois at Urbana-Champaign

Evaluating The Impacts Of Farmers’ Behaviors On A Hypothetical Agricultural Water Market Based On Double Auction, Erhu Du, Ximing Cai, Barbara Minsker

Daugherty Water for Food Global Institute: Faculty Publications

Agricultural water markets are considered effective instruments to mitigate the impacts of water scarcity and to increase crop production. However, previous studies have limited understanding of how farmers’ behaviors affect the performance of water markets. This study develops an agent-based model to explicitly incorporate farmers’ behaviors, namely irrigation behavior (represented by farmers’ sensitivity to soil water deficit k) and bidding behavior (represented by farmers’ rent seeking l and learning rate b), in a hypothetical water market based on a double auction. The model is applied to the Guadalupe River Basin in Texas to simulate a hypothetical agricultural water market under …


Landowner And Practitioner Perspectives On Private Land Conservation Programs, Michelle L. Lute, Caitlyn R. Gillespie, Dustin R. Martin, Joseph J. Fontaine 2017 University of Nebraska— Lincoln

Landowner And Practitioner Perspectives On Private Land Conservation Programs, Michelle L. Lute, Caitlyn R. Gillespie, Dustin R. Martin, Joseph J. Fontaine

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Efforts to reverse declines in native grasslands benefit from agricultural policies that encourage private land conservation. The U.S. Department of Agriculture’s Conservation Reserve Program (CRP) improved conservation across landscapes but enrollment has declined. We used sequential exploratory mixed methods to compare landowner and conservation practitioners’ perceptions, evaluate perceived benefits, and identify potential improvements to CRP. Focus groups of practitioners informed a quantitative survey of landowners who had properties >160 total acres in Nebraska. Results suggest potential misalignment in perceptions between practitioners and landowners. Practitioners were concerned that conservation, especially of wildlife, was secondary to profit. But the majority of landowners …


Modeling The Effectiveness Of Riparian Restoration On Stream Shading In The Clackamas River Basin, Rachel Barksdale 2017 Portland State University

Modeling The Effectiveness Of Riparian Restoration On Stream Shading In The Clackamas River Basin, Rachel Barksdale

ESM Colloquium

Rivers and streams within the Clackamas River Basin are not currently meeting water quality standards in terms of temperature. The Clackamas River Basin Council (CRBC) designed a restoration program to address the thermal loading on behalf of Portland General Electric (PGE) in which native trees and shrubs are planted along streams to restore riparian canopy cover. Solar radiation can be blocked by restoring canopy cover and is an effective way to provide shade, as well as providing ancillary environmental benefits such as enhanced wildlife habitat and erosion control. Stream and vegetation data were collected at nine sites to model the …

In this article we summarize histories of nonlinear, complex interactions among societal, legal, and ecosystem dynamics in six North American water basins, as they respond to changing climate. These case studies were chosen to explore the conditions for emergence of adaptive governance in heavily regulated and developed social-ecological systems nested within a hierarchical governmental system. We summarize resilience assessments conducted in each system to provide a synthesis and reference by the other articles in this special feature. We also present a general framework used to evaluate the interactions between society and ecosystem regimes and the governance regimes chosen to mediate …

Escherichia Coli As A Water Quality Indicator Organism: A Case For Responsive, Science-Based Policy, Sarah M. Mclarnan

All College Thesis Program, 2016-2019

Water quality indicator organisms such as E. coli are used in the monitoring of recreational waterbodies to indicate the presence of fecal contamination. In 2009, a 1.5-mile stretch of Plum Creek in Stearns County, MN was classified by the Minnesota Pollution Control Agency as impaired due to high levels of E. coli. Citizen science to investigate the source of this contamination began in 2014 and with the addition of student research from CSB/SJU in 2016. This thesis presents results of the 2016 study, supplemented by summary of Minnesota water quality policy and recent research on indicator organisms. The 2016 …


Mechanistic Modeling Of Insecticide Risks To Breeding Birds In North American Agroecosystems, Matthew Etterson, Kristina Garber, Edward Odenkirchen 2017 USEPA Office of Research and Development

Mechanistic Modeling Of Insecticide Risks To Breeding Birds In North American Agroecosystems, Matthew Etterson, Kristina Garber, Edward Odenkirchen

United States Environmental Protection Agency: Publications

Insecticide usage in the United States is ubiquitous in urban, suburban, and rural environments. There is accumulating evidence that insecticides adversely affect non-target wildlife species, including birds, causing mortality, reproductive impairment, and indirect effects through loss of prey base, and the type and magnitude of such effects differs by chemical class, or mode of action. In evaluating data for an insecticide registration application and for registration review, scientists at the United States Environmental Protection Agency (USEPA) assess the fate of the insecticide and the risk the insecticide poses to the environment and non-target wildlife. Current USEPA risk assessments for pesticides …

Financial Assessment Of Agricultural Lands At Risk To Coastal Salt Marsh Migration In Relation To Climate Change Induced Sea Level Rise In Dorchester County, Maryland, Jewell Porter

Sustainability and Social Justice

The increasing rate and effects of sea level rise is a major environmental concern in the Chesapeake Bay. This paper evaluates the impacts of rising sea level on coastal salt marshes and the surrounding agricultural lands at risk in Dorchester County, Maryland to build off existing environmental monitoring work performed by NOAA’s Sentinel Site Program. The results of the spatial analysis were used to estimate monetary benefits to incentivize farmers to protect these marshes by making their land available for marsh migration to occur. Looking at three scenarios of sea level rise and marsh migration, grain crops (corn, soybeans, and …


Elucidating The Effects Of Thiamethoxam Neonicotinoid On Honey Bee Learning Using The Proboscis Extension Response, David J. Shepherd 2017 East Tennessee State University

Elucidating The Effects Of Thiamethoxam Neonicotinoid On Honey Bee Learning Using The Proboscis Extension Response, David J. Shepherd

Undergraduate Honors Theses

In this study, the effects of the neonicotinoid pesticide, thiamethoxam, are examined through the Proboscis Extension Response (PER) in honey bees (Apis mellifera). PER is a form of classical conditioning applied to honey bees through scent and reward association which quantifies learning rates. Results between groups treated with thiamethoxam did not differ significantly from untreated control groups. Potential reasons for these results are discussed. The method and experimental apparatus for testing the PER assay are also discussed.

Remotely Sensed Heat : Variation And Change In Surface Urban Heat Islands In A Temperate Eco-Region Of The United States., Jeremy Sandifer

Electronic Theses and Dissertations

Urban heat island (UHI) is a term used to describe increased surface and atmospheric temperatures in an urban core relative to surrounding non-urbanized areas. To examine the variability introduced into derived estimates of the surface UHI, this study constructs and compares multiple remotely sensed indicators of the surface UHI for major metropolitan cities of a temperate eco-region of the United States. The Moderate Resolution Imaging Spectroradiometer (MODIS) 8-day, 500-meter product (MOD11A2) is the source data used to calculate six different RS-derived UHI indicators for the year 2002 to 2012. The different SUHI indicators are evaluated using the Spearmans Rho rank-order …
