The south west Pacific is affected by climatic phenomena such as ENSO (El Niño Southern Oscillation) or the PDO (Pacific Decadal Oscillation).Near-monthly resolution calibrations of Sr/Ca, U/Ca and δ18Oc were made on corals taken from tactical pen New Caledonia and Wallis Island.These geochemical variations could be linked to SST (sea surface temperature) and SSS (sea surface salinity) variations Cleansers over the last two decades, itselves dependent on ENSO occurrences.On the other hand, near-half-yearly resolution over the last century smoothes seasonal and interannual climate signals, but emphasizes low frequency climate variability.
