Stable isotope and growth records in corals from the island of Tobago: Not simply a record of the Orinoco

Age models were constructed using the AnalySeries program [Paillard et al., 1996]. We used tie points to connect the lowest (highest) d18O values to the warmest (coolest) temperatures in the instrumental SST record to establish each year.The use of coral Sr/Ca values instead of coral d18O values to construct the age model results produces a similar chronology. The geochemical data were then interpolated to give monthly d18O values. The geochemically based age models were confirmed via comparison with ages determined by counting of skeletal density-band couplets in the X-ray images of the coral slab.

Coral d18O variations at Rabaul are likely driven by the combined variations in SST and seawater d18O (and hence SSS) given the general climatology of the WPWP

Coral d18O variations are modestly correlated with SST variations over their common period of overlap (1970? 1993), both in terms of the monthly and monthly anomaly time series

The monthly coral d18O anomaly time series at Rabaul yields no significant correlation with the instrumental SSS record, despite the fact that similar coral records from Fiji [Le Bec et al., 2000] and Vanuatu [Kilbourne et al., 2004] have been demonstrated to reflect SSS variations. It is possible that the monthly coral d18O anomaly record does reflect local SSS variability at Rabaul and the observed low correlation between these two variables results from differences between the ship-track SSS record and the actual SSS variability at Rabaul
