| Zusammenfassung |
| 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 New Caledonia and Wallis Island. These
geochemical variations could be linked to SST (sea surface temperature) and
SSS (sea surface salinity) variations 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. |
