Description:

We perform replication tests using monthly variations in Sr/Ca and d18O in four cores from three Porites lutea coral heads from New Caledonia to assess the reproducibility of coral-based climate records. Coral Sr/Ca (d18O) records are well correlated to each other and to the instrumental SST record (1967 – 1992), especially in terms of differences in the mean values of 25-year SST records (
