Black circle represents volume weighted average isotopic composition of rainfall collected in this study. Open triangle represents isotopic composition of rainfall reported by Swart ct al., 1989. significantly more negative than zero at —239%c and — respectively. A positive linear relationship exists between 5'^0 and salinity for the Whitewater Bay and Ten Thousand Islands areas (Table 2). The linear cot relation coeffi- cient (R-) for the Whitewater Bay and Ten Thousand Islands is and respectively (p < ). The predicted intercept of the linear relationship at zero salinity is close to zero for both the Whitewater Bay (+) and Ten Thousand Islands areas (, Table 2). There is no strong linear correlation between 8'^C and salinity throughout all of Florida Bay ( 7). Similarly there is no strong linear coirelation between 8'"C and salinity within the four regions of Florida Bay (Table 2; Text-fig. 8), except for the Inner Florida Bay area. The Inner Florida Bay area. Whitewater Bay area and the Ten Thousand Islands areas have similar cor- relations (R- = ; p < ) between 5'^C and salin- ity. Corals The 8"C and 8"*0 data for the skeleton of the coral collected from Lignumvitae Basin have been reported previously (Swart et al., 1996; 1999). The average an- to.
