basis: This relationship between the d180 of the water (~w) and salinity is shown in Eqn. 2 and Fig. 2 (r = +0.71, n = 38, p > 0.05). Salinity = 4.98dw + 25.89 (2) Combining Eqns. (1) and (2), an expression (Eqn. 3) is derived expressing salinity in terms of the ~c and T. Salinity = 4.98delta18Ocoral + 1.18T + 19.62 (3) The confirmation of a positive correlation between salinity and the d180 (ffthe water (dw) seems to discount the notion that significant amounts of freshwater from Shark Slough, which is isotopically enriched in lsO (Meyers et al. 1993), is influencing the salinity of Lignumvitae Basin. If this water were influencing the salinity of Lignumvitae Basin then either an inverse correlation or no correlation at all would be expected between ~w and salinity.
