Temperature, dissolved oxygen (DO), salinity, and pH are critical abiotic factors influencing coral reef ecosystems. Enclosed lagoons, such as the one at Peanut Island, often experience reduced water exchange, making them prone to environmental fluctuations that may stress corals. The purpose of this project was to investigate potential correlations between water quality and coral health within the Peanut Island Coral Nursery Lagoon in Palm Beach County, Florida over a year-long period. Three Onset HOBO data loggers were deployed: U22-001 to measure temperature and pH; U26-001 to measure dissolved oxygen; and U24-002-C to measure salinity. The data loggers were deployed near the established coral nursery in the lagoon to continuously monitor water quality. Water quality data was paired with monthly GoPro photo and video surveys of corals to assess bleaching, disease, or stress. As this study continues, it is expected that there will be seasonal fluctuations in temperature and DO levels due to overall increased water temperatures. Results will provide baseline environmental data, inform management, and evaluate correlations between lagoon water quality and coral health.
