Dissolved radium isotopes for river and estuary samples collected from November 2022 to August 2023 along the West Florida Shelf

Physicochemical parameters and specific activities of dissolved radium isotopes (Ra-223, Ra-224, Ra-226, Ra-228), Th-228, and Ac-227, collected from rivers and estuaries along the West Florida Shelf from November 2022 to August 2023. 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. 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 radium and parent isotopes have been measured to trace boundary sources of nutrients and metals entering the West Florida Shelf.
