Seasonal Water Quality Changes in the Lower St. Johns River

Hello all!

The water quality of the St. Johns River is affected by hurricanes and storms. Hurricanes or major storms can affect the water quality by lowering the dissolved oxygen levels and changing the temperature of the water, thereby affecting riverine biodiversity. This research uses water quality data collected at 8 different sites along the lower St. Johns River. Data was analyzed using the seasonal averages from 2017 to 2020 along the Lower St. Johns River. The three variables analyzed were dissolved oxygen, temperature, and chlorophyll a. Through this analysis, a clearer picture of how increased storm activity and freshwater input affects the water quality of the Lower St. Johns River.
