Evaluation Of Autonomously Measured Alkalinity, Ph, And Pco2 Variability On A Coral Reef, Brittany Peterson

Graduate Student Theses, Dissertations, & Professional Papers

Currently, our understanding of alkalinity (A_T) variability in highly dynamic environments such as coral reefs is limited by the dearth of A_T measurements. In order to better characterize these environments, high temporal resolution A_T data are needed. This work employed the newly developed Submersible Autonomous Moored Instrument for Alkalinity (SAMI-alk), a fully autonomous in situ A_T analyzer, to study seawater A_T variability. The main goals of this research were to evaluate the utility of combining the SAMI-alk data with currently available in situ measurements of pH and partial pressure of carbon dioxide (p …

Using Multiple Environmental Tracers To Investigate The Relative Role Of Soil And Deep Groundwater In Stream Water Generation For A Snow-Dominated Headwater Catchment, Isabellah V. Von Trapp

Graduate Student Theses, Dissertations, & Professional Papers

In this study, seasonal fluctuation of environmental tracers in stream flow, soil water, and deep bedrock groundwater were used to constrain the role of deep bedrock groundwater in streamflow generation for a mountainous headwater catchment. Synoptic measurements of stream discharge, ²²²Rn, specific conductivity and major ion concentrations were measured throughout the water year over a 5 km reach of Cap Wallace Creek in the Lubrecht Experimental Forest, Montana, U.S.A. with the intention of understanding groundwater – surface water interactions across spatial and temporal scales. Stage measurements were continually recorded at seven stilling well locations along the reach. Discharge measurements …

Policy Analysis: Alaska Salmon Hatcheries, Jessica Eller

Graduate Student Theses, Dissertations, & Professional Papers

Using an adapted Ecological Risk Assessment (ERA) - Evaluation, this study analyzes policy regulating Alaska salmon hatcheries to evaluate its effectiveness at sustaining wild salmon runs.When Alaska became a state in 1959, its salmon industry was suffering from years of overfishing. Runs were at an all-time low, prompting constitutional drafters to mandate management of salmon via the sustained yield principle. The hatchery system that operates today and is responsible for a third of the commercial catch each year was put in place in the 1970s to help supplement depressed salmon runs. The effects of hatchery salmon on wild salmon populations …

Mediating Cultural Border Crossings Between American Indian Tribal College Students And Natural Resources Science Learning Using Culturally Congruent Education, Shandin Hashkeh Pete

Graduate Student Theses, Dissertations, & Professional Papers

This study is motivated by two research questions: (1) How does Culturally Congruent Instruction (CCI) influence American Indian (AI) students' attitudes and achievement in natural resources science at a tribally controlled college/university (TCU)? And (2) What is the nature of the relationship between CCI course modifications and changes (or lack of) in AI students' science attitudes and achievement at a TCU? Findings developed a Culturally Congruent Instructional Framework (CCIF) for use in TCUs and beyond.

Previous research suggest that AI students and tribal college science must find congruence for the student to cross cultural boundaries of the institution. TCUs can …

40 Years On The International Flathead: An Assessment Of Transboundary River Governance, Jedd Sankar-Gorton

Graduate Student Theses, Dissertations, & Professional Papers

Global population growth, climate change, and industrialization, are putting extreme pressures on worldwide freshwater supplies (Cosens 2010). Of the global freshwater supplies, transboundary water sources play a crucial role in sustaining populations. Over 40% of humans on Earth rely on a transboundary river or lake for access to water, and 90% of the world’s population lives in countries that share bodies of water with at least one other country (UN 2008). Taken together, the motivations for improving governance of transboundary water systems have never been stronger. To meet the challenges associated with transboundary water governance, researchers working at multiple scales …

Understanding The Food Water Nexus: Characterizing The Impact Of Climatological Anomalies On Agrosystems, Patrick M. Wurster Jr.

Graduate Student Theses, Dissertations, & Professional Papers

Climate variability at global and regional scales is escalating with increased atmospheric carbon and is expected to magnify the intensity and duration of meteorological extremes, especially droughts. From the many environmental stresses that diminish crop production (e.g., soil salinity, frost, soil erosion) drought is one of the most prevalent. This study focuses on the sensitivity of three key crops produced in the northwestern United States to climatological anomalies, while controlling for attribution using anomalies in price. The study differs from similar studies in that we focus on variability in production which captures both yield (tonnes/ha) and cropping area (ha), as …

Directional Non-Covalent Interactions: Exploring The Nuances Of Halogen Bonds And Hydrogen Bonds In Solution And The Solid-State, Nicholas Blouin Wageling

Graduate Student Theses, Dissertations, & Professional Papers

Molecules interact in numerous ways. Halogen bonding is one of the most newly discovered and poorly understood non-covalent interactions. However, this attractive force may be a useful tool for chemists in various disciplines. The directional nature, and competitive strength of the interaction makes it a promising alternative to hydrogen bonding based molecules. Indeed, through crystal structures and solution phase anion titrations, this work has shown that a halogen bonding scaffold can outperform its hydrogen bonding analogue not only in overall interaction strength, but also in resistance to inactivation from polar solvents (an important feature in anion receptors, organocatalysts, and many …

Transfer Of Graphing Skills From Math To Chemistry, Brittany Danielle Busby

Graduate Student Theses, Dissertations, & Professional Papers

Most students begin their university studies with adequate mathematical skills to succeed in general chemistry. However, students have a demonstrated difficulty with the application of math in a chemistry context. The ability to apply skills to new contexts is known as transfer, and understanding and enhancing transfer of graphing skills into the context of chemistry is the primary purpose of this investigation. Graphing skills were selected as the area of emphasis because they provide a strong conceptual link between math and chemistry.

This is a two-phase, sequential, quasi-experimental, mixed-methods study. In the first phase of the study, the quantitative research …

Estimating Groundwater Inflow And Age Characteristics In An Alluvial Aquifer Along The Little Wind River, Wyoming, Derek Goble

Graduate Student Theses, Dissertations, & Professional Papers

We synoptically sampled a 2 km gaining reach of the Little Wind River in central Wyoming for ²²²Rn, CFCs and SF₆ to determine the distributed volumes and locations of discharge and estimate alluvial groundwater age characteristics. ²²²Rn was sampled in the stream, shallow in-stream piezometers and nearby alluvial groundwater wells to determine the volume and spatial distribution of groundwater discharge to the river. Age tracers, CFC and SF_6, sampled in the stream, shallow in-stream piezometers and in alluvial groundwater wells were then used to determine whether in-stream samples are capable of constraining the residence time distribution …

Quantifying Effects Of Using Thermally Thin Fuel Approximations On Modelling Fire Propagation In Woody Fuels, David Blasen, Jesse Johnson, William Jolly, Russell Parsons

Graduate Student Theses, Dissertations, & Professional Papers

In this paper, we quantify the effects of the thermally thin fuel approximations commonly made in numerical models that eliminate temperature gradients within a heated object. This assumption is known to affect the modeled ignition and burn behavior, but there is little research on its impact, particularly in larger fuels or in numerical models including moisture and chemical decomposition of fuels.

We begin by comparing modeled to observed ignition times and burn rates. To constrain variability in the material properties of wood and focus on variability caused by fuels assumed to be thermally thin, we conduct experiments using thermogravimetric analysis …

Effect Of Neuromodulation Of Short-Term Plasticity On Information Processing In Hippocampal Interneuron Synapses, Elham Bayat Mokhtari

Testing The Limits Of Temporal Stability: Willingness To Pay Values Among Grand Canyon Whitewater Boaters Across Decades, Christopher J. Neher, John Duffield, Lucas Bair, David Patterson, Katherine Neher

Mathematical Sciences Faculty Publications

We directly compare trip willingness to pay (WTP) values between 1985 and 2015 stated preference surveys of private party Grand Canyon boaters using identically designed valuation methods. The temporal gap of 30 years between these two studies is well beyond that of any tests of WTP temporal stability in the literature. Comparisons were made of mean WTP estimates for four hypothetical Colorado River flow level scenarios. WTP values from the 1985 survey were adjusted to 2015 levels using the consumer price index. Mean WTP precision was estimated through simulation. No statistically significant differences were detected between the adjusted Bishop et …

Chemistry and Biochemistry Faculty Publications

Climate, land use, and other anthropogenic and natural drivers have the potential to influence fire dynamics in many regions. To develop a mechanistic understanding of the changing role of these drivers and their impact on atmospheric composition, long-term fire records are needed that fuse information from different satellite and in situ data streams. Here we describe the fourth version of the Global Fire Emissions Database (GFED) and quantify global fire emissions patterns during 1997-2016. The modeling system, based on the Carnegie-Ames-Stanford Approach (CASA) biogeochemical model, has several modifications from the previous version and uses higher quality input datasets. Significant upgrades …

For Many In Puerto Rico, ‘Energy Dominance’ Is Just A Newname For Us Colonialism, Catalina M. De Onis

Environmental Studies Faculty Publications

The Trump administration has made “achieving American energy dominance” a central policy goal. President Trump asserts that “energy dominance” requires expanding nuclear development, increasing coal and natural gas exports, building transnational pipelines and accessing offshore oil and gas deposits. These efforts, Trump contends, will maximize the nation’s “boundless capacity” for energy production, including spreading U.S. fossil fuels around the globe, to showcase its independence from foreign oil.
