Figure 1. Seawater d18O (dw)-salinity relationships using different end-member dw and slopes. Modern relation values of -8.9 SMOW and s = 0.27 are from Pierre (in press). Depleted dw values of -30 and -40 SMOW and steeper slopes are used for sensitivity tests. Solid square shows modern mean Mediterranean salinity.
