Abstract: Great Salt Lake (GSL) is bordered by many large residential and industrial developments. Oil refineries, metal fabricators, and a copper mine are in the same watershed as GSL. Most of these anthropogenic sources of metals enter GSL by way of Farmington Bay, which also receives effluent from four different wastewater treatment sites. In this study, we investigated microbial pollution and metal concentrations in water and sediment in Farmington Bay and compared them to concentrations found at proximal and distal sites in GSL around Antelope Island. We found heterotrophic bacteria from Farmington Bay that can survive the high salinity of GSL, as well as some freshwater algae found in Farmington Bay at distal GSL sites. Additionally, coliform levels exceeded Utah safety standards at every site. We found evidence of Farmington Bay as a source of Fe, Pb, and Ni in water and Zn, Cu, Fe, Ni in sediments. Our results highlight that Farmington Bay could be a significant source of microbial pollution in GSL and that further research is necessary to constrain the sources and impacts of metal pollutants.
Colton Layton - "Value and Demographics of the Ogden Trails System"
Mentor: Bryan Dorsey
College: Social & Behavioral Sciences
Abstract: The purpose of this research is aimed to focus on the importance and significance of the trails systems within Ogden, Utah. The research methods obtained both primary and secondary data acquisition techniques to achieve the research goal. In the research conducted thus far, it has been noticed that there is a correlation between property values and trails within the study areas. There has also been research derived from both primary and secondary sources regarding the motivations that people choose to use trails and why, ranging from recreational use to personal promotion of well-being. Throughout this research the goal was aimed to obtain an understanding and importance of having trail networks around an urban center such as Ogden, Utah. Over the research period, the objective of surveying individuals regarding trail frequency and usage was used and analyzed to gain a better understanding of the significance that the trails bring to those that use the recreational system. This research was obtained to gain a more thorough understanding of who is using the trails, what they are using the trails for, frequency of use of individual trails, and understanding who does and does not benefit from the trails system.
Austin Gottfredson - "Constraints of Dark Matter"
Mentor: Jonathan Cornell
Abstract: Dark matter is a rich topic in physics research. Gravitational observations in space indicate the presence of an invisible (dark) matter. Dark matter is not thought to interact with light making it difficult to detect. Nevertheless, there are other methods to detect its presence. One way is direct detection where we study possible interactions dark matter may have with (run-of-the-mill) matter. This presentation focuses on indirect detection. It is theorized that dark matter may self-annihilate and create various products including photons. These photons have a high energy and can be detected by telescopes such as NASA's Fermi satellite. This data is publicly available and ready to be analyzed with dark matter models to find constraints on what dark matter is. In this study, I use simple particle dark matter theories and Fermi data from dark matter rich galaxies to constrain the upper limit of the annihilation cross section of dark matter.
Jonathan Rizzo - "The Bizarre Nature of Polars"
Mentor: Stacy Palen
Abstract: Cataclysmic variables are some of the most closely studied objects in the night sky. They consist of a white dwarf-red dwarf binary system with an orbital period measured in hours. Occasionally, they can increase in brightness thousands of times. When the white dwarf has a particularly strong magnetic field, the system is called a Polar. In this presentation, we will introduce new and future observations taken with the research telescope at Weber State University that help us characterize the individual components and orbital parameters of the system.
Hannah Leishman - "Understanding and Attitudes of Federal Reserve"
College: Business & Economics
Abstract:There is currently little research when it comes to examining the general population's understanding and attitude of the Federal Reserve Bank. This research project aims to add to this lack of knowledge. In order to study this problem a survey will be sent to 100 random people across the United States. The results will be examined using regression models to test what factors contribute to individuals understanding and attitude of the Federal Reserve. Based off of other similar studies it is expected that there will be a lack of understanding of the Federal Reserve. It is also expected that attitude will be lower considering the recent economic downturn due to the COVID-19 outbreak.
