Spatial and Temporal Nutrient Trends in a Shallow, Eutrophic Freshwater Bay
Many coastal bays contain farmland within their watersheds. Agricultural runoff contains high concentrations of nitrogen (N) and phosphorus (P), which drains into these systems throughout the year. This can cause harmful algal blooms (HABs) that impact animal and human health. Understanding the trends and behaviors of N and P in these ecosystems will help us to control HABs. Sandusky bay is a shallow coastal bay in Lake Erie, which typically experiences harmful algal blooms (HABs) every year. Our goal was to determine how N and P concentrations vary temporally and spatially in Sandusky Bay. Levels of N and P in the water were measured at multiple timepoints and locations over three summers (2017-2019). For both N and P, the nutrient concentrations declined along the flow path from the West, where the Sandusky River empties into the bay, to the East where the Bay connects with Lake Erie. N concentrations decreased throughout the season, while P was more variable. Across sampling sites, surface water nutrient concentrations reflect gradients in sediment geochemistry and nutrient content. Continued research will explore mechanisms of N and P sediment removal in Sandusky Bay and adjacent wetlands.
