Three Porites lutea coral colonies were drilled at Tonga on the islands of Ha’afera, Malinoa, and Nomuka Iki. Two Fiji Porites lutea cores (Fiji 1F and Fiji AB) were used in this study. Update October 2008: Tonga core TM1 exhibits fungal pigments and resulting slower growth rate (due to fungal infestation), and the authors believe this should preclude the use of data from this core in the index. Therefore they have recalculated the index with just four corals (Fiji 1F, Fiji AB, Tonga TH1, and Tonga TNI2). The new 4-coral index is almost identical to the 5 coral version. Please see Linsley et al., 2008 for discussion of the problems with coral TM1. ABSTRACT SUPPLIED BY ORIGINATOR: In the South Pacific, interdecadal-decadal oceanic and atmospheric variability, referred to as the Interdecadal Pacific Oscillation (IPO), is most pronounced in the South Pacific Convergence Zone (SPCZ) salinity front region. Here we have used annual average oxygen isotope (d18O) time series from five coral cores collected from Fiji and Tonga in this region to construct a Fiji-Tonga Interdecadal-Decadal Pacific Oscillation (F-T IDPO) index of low-frequency (>9 and <55 years) climate variability back to 1650 A.D. We first demonstrate the consistency between this F-T IDPO index and a mean sea level (MSL) pressure-based SPCZ position index (SPI) (1891–2000), thus verifying the ability of coral d18O to record past interdecadal-decadal climatic variations in this region back to 1891. The F-T IDPO index is then shown to be synchronous with the IPO index (1856–2000), suggesting that this coral-based index effectively represents the interdecadal-decadal scale climate variance back to 1650. The regularity of the F-T IDPO index indicates that interdecadal-decadal variability in the SPCZ region has been relatively constant over the past 350 years with a mean frequency of ~20 years (variance peaks near 11 and 35 years). There is a consistent antiphase correlation of the F-T IDPO index and the interdecadal-decadal components in equatorial Pacific coral d18O series from Maiana and Palmyra. This observation indicates that the eastward expansion (westward contraction) of the eastern salinity front of the Western Pacific Warm Pool (WPWP) occurs simultaneously (±<1 year) with the westward (eastward) shift of the SPCZ salinity front during positive IPO (negative IPO) phases. This is the same relationship observed during the phases of the El Niño Southern Oscillation.
