Dissolved iron and iron isotopes for SGD well, river, and estuary samples collected between November 2022 and March 2024 along the West Florida Shelf

Dissolved iron concentration and iron isotope ratios (δ56Fe) collected from rivers, estuaries, and submarine groundwater wells along the West Florida Shelf from November 2022 to March 2024 as part of the STING GEOTRACES Process Study (GApr18), where STING = Submarine Groundwater Discharge, Trichodesmium, Iron & Nitrogen in the Gulf of Mexico. Rivers include the Alafia, Caloosahatchee, Hillsborough, Manatee, and Peace rivers, at upstream and downstream locations. Estuaries include surveys along Tampa Bay, Charlotte Harbor, and the Caloosahatchee River Estuary. Three submarine groundwater well transects are included. This project investigates how boundary sources, including rivers and submarine groundwater discharge, deliver important nutrients and metals to the coastal ecosystems of the West Florida Shelf. Here, dissolved iron concentrations and isotope ratios have been measured to trace boundary sources of iron entering the West Florida Shelf.
