El Nino events bring warmer and rainier conditions to the Northern Line Islands, conditions which constructively act to decrease coral d18O. The opposite climatic effects occur during cool La Nina extremes, driving an increase in coral d18O.

Modern Line Islands coral d18O records are high- ly correlated to the regional-scale NIi¿½O3.4 index (defined as the average of instrumental SSTs from 5i¿½S to 5i¿½N, and from 120i¿½ to 170i¿½W)

The geochemicalsignature of the corals appears to be influenced by the interdecadal variability of terrestrial runoff associated withrainfall; moreover, these low-frequency variations arelikely initiated by PDO activity. Values of coral(delta)d18O (d18Osw) andd18O are mainly controlled by terrestrial runoff.
