Groundwater flowing into the ocean plays an important but often hidden role in transporting nutrients and contaminants to coastal waters. While this flow occurs both near the shoreline and farther offshore, most current estimates focus only on the nearshore portion. In this study, we developed a more comprehensive method to estimate total submarine groundwater discharge into the ocean along the Florida coast, accounting for both nearshore and offshore components. Nearshore SGD occurs close to the shoreline and includes both fresh groundwater and recirculated seawater. Offshore SGD, on the other hand, takes place farther from the coast, often beneath the continental shelf, and is primarily driven by hydrodynamic forces such as tides, waves, and ocean currents. We found that offshore groundwater discharge plays a much larger role in transporting nutrients and supporting biogeochemical cycling, extending across Florida’s continental shelf. In fact, tide-driven groundwater-seawater exchange was strongly linked to total groundwater discharge across the region. We also identified 54 coastal hotspots where groundwater enters the ocean at higher rates. These findings improve our understanding of how nutrients and freshwater move through the coastal environment and can help guide efforts to protect water quality and ecosystem health along the Florida coast.
