Relative chronologies were constructed by assigning the maximum ?18O point for a given year to January 15th and linearly interpolating ?18O datapoints in between these tie points, following the procedure outlined in Cobb et al., 2002 for the Palmyra modern and fossil corals U/Th dates used to estimate absolute ages

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)
