indicated, “a generally west-to-east movement of water through the interior of the Bay that eventually exits through the tidal channels between keys on the southeastern and southern sides of the bay.” These authors concluded their analysis of 15 years of physical observations by emphasizing that “[a]veraging over tidal periods and the longer time scales associated with meteorological forcing…reveals transport pathways that represent a clear coupling between Gulf and Atlantic sides of the Keys. Gulf-to-Atlantic transport can be either around the Keys…or it can involve a more complex route through Florida Bay and the tidal channels…” Numerous drifter studies have shown that Shark River Slough water tends to pass along the western boundary of Florida Bay and must often have access to the central Bay (Lee et al., 2002). Boyer et al. (1999) believed that they could see the effect of “a freshening of the waters of the southwest Florida Shelf from Shark Slough drainage” on salinity declines in western Florida Bay. Additional qualitative information about the linkage of the Bay with Shark River Slough discharge is provided by D’Sa et al. (2002) on the basis of remote sensing of salinity patterns. These researchers concluded that “Gulf waters entering the bay primarily from the northwest (near East Cape) entrain freshwater from the Shark River Slough and other smaller rivers in southwest Florida as indicated by the lower salinities observed in the vicinity of Cape Sable…” (Figure 2).
