Graduate Exit Seminar - Holly Stanley

Plan to join Holly Stanley's graduate exit seminar on July 5, 2023, at 1:00 pm in Kottman Hall 333 or via Zoom. Holly will present, "Monitoring Physical, Chemical, and Biological Changes in a Eutrophic Ohio Lake Being Treated for Harmful Algal Blooms with Nanobubble Ozone Technology."

Abstract: Cyanobacterial harmful algal blooms (CHABs) occur in lakes due largely to excess nutrient runoff and are an increasing problem in the agricultural watersheds of Ohio. The need for an efficient, cost-effective treatment for CHABs is critical to preserve the health of inland lakes throughout Ohio and the country. Nanobubble ozone technology (NBOT) is an emerging treatment designed to remediate CHABs and facilitate nutrient transformation through ozonation using nanobubbles as a delivery method. While some work has been done on NBOT and its impacts on cyanobacteria, not much is known about how NBOT may impact physicochemical parameters in lakes. My thesis research explores the physical, chemical, and biological changes seen in a small eutrophic lake as it underwent NBOT treatment for CHABs. I will discuss the relationships between chemical parameters such as nitrogen, phosphorous, and dissolved organic carbon concentrations and how they interact with biological changes in the cyanobacterial community seen throughout the season and NBOT treatment periods.
