| Zusammenfassung |
| Carbon source-sink dynamics across a land surface-aquatic continuum are difficult to
quantify. Here, we use a combination of water column SF6 deliberate tracer releases, pCO2
mapping, discrete measurements of pH, TAlk, DIC, and DOC, and autonomous
measurements of CDOM, pCO2, and pH to determine air-water CO2 exchange and
the sources and sinks of DIC and DOC to investigate the carbon balance of Shark
River, which originates in the freshwater marshes of Everglades National Park.
Shark River is tidal in its lower reaches and passes through the largest continuous
mangrove forest in North America before discharging to the Gulf of Mexico. Our
measurements provide a means to determine the fate of mangrove-derived carbon in Shark
River, and serve as a model for applying similar methods in other aquatic systems. |
