b'Social Media, App, and Campus SafetySpencer Ely, Amber Givens, Preyah James, Edward Moore, Maya Opara-Nadi, Grier Rogers, Tyson Ross, Joshua Saunders, Darien Shannon, Aaron Sirmons, Abigail Spartling, and Lamyah Wimberly, Department of Physics, Astronomy, Geosciences and Engineering Studies Faculty Sponsor: Jia Lu, Department of Physics, Astronomy, Geosciences and Engineering StudiesCampus safety is crucial to the university community. Research has shown that social media has changed the way we communicate, analyze and gather information. Over the past few years, social media and apps have been utilized in emergency management and disaster response in numerous ways, and they offer a wide range of capabilities and levels of interactivity that can be beneficial for campus security. However, there has been limited research on social media and app usage on campus safety, as well as their associated benefits and shortcomings. This research attempts to bridge the gap by exploring social media and app usage in a medium-sized university in Georgia. Survey questions were developed and distributed among the student population throughout the campus to explore the patterns of social media use for campus safety. The results suggest that social media and apps were widely used as a complementary channel for communication during emergencies, including criminal incidents and natural disasters. Social media and apps were able to reach some students who otherwise could not obtain updated information in case of emergency. However, some students were not aware of the campus safety channel. Overall, the study suggests universities should continue to use social media and apps during emergencies and expand all modes of communication applications during emergencies that can allow for wide-scale interaction. Sediment Analysis of Overwash Fans Produced by Recent Hurricanes on Jekyll Island, GeorgiaRobert J. Pecenka, Department of Physics, Astronomy, Geosciences and Engineering Studies Faculty Sponsor: Dr. Paul Vincent, Department of Physics, Astronomy, Geosciences and Engineering StudiesGeorgias barrier islands are a major geologic boon for the State because they protect the mainland from the heavy erosion due to storms and tidal processes of the Atlantic Ocean. Hurricanes have a dramatic impact on barrier islands through the processes of erosion and accretion that is the result of strong winds and storm waves. This study is an overview of the amplified erosive processes of those storms and describes how the sediment distribution on Jekyll Island has changed as a result of recent hurricanes. The storm surge from Hurricanes Matthew (2016) and Irma (2017) created several overwash fans on the northern end of the Jekyll Island and these depositional features were examined for this research. Sediment cores from the overwash deposits were analyzed for composition, particle sizes, and their variation with depth to determine the origins of the sediments.65'
