“…Although there are a limited number of studies that quantify these fluxes, the results suggest that the fluxes may be important globally. The Future of Ocean Chemistry (FOCUS) workshop sponsored by NSF concluded that land‐sea exchange at ocean margins and advective chemical transport through sediments and coastal aquifers would be among the major themes to be addressed during the next few decades [ Mayer et al , 1999].…”

[1] A physical model based on determining the fraction of the tidal prism that returns to the estuary on the next high tide is used to estimate the flushing time of the Okatee River estuary. Ra is used to determine the apparent age of water in the estuary. These ages range from 1.6 to 5 days, with an average of 3.4 days. These three independent estimates are in remarkably close agreement, certainly within the error of each estimate. We use these residence times to develop a mass balance model for the radium isotopes in the Okatee estuary. We consider decay, mixing, sedimentary input, river input, and submarine groundwater discharge (SGD). The major loss term for each isotope is mixing with water in Port Royal Sound; the major input for each isotope is SGD. At steady state these terms must balance. Knowing the water age and the radium isotope composition of groundwater entering the Okatee allows us to estimate an average SGD flux of 1 m 3 /s. The SGD flux is a factor of 3-4 greater during the summer relative to the winter. This SGD supplies a considerable quantity of nutrients and carbon into the Okatee system.
