“…Recent efforts have substantially improved the spatial and temporal coverage of well-dated, high-resolution proxy records (tree rings and corals) for these regions [e.g., for the North Pacific: Davi et al (2002), D'Arrigo et al (2004), and Jacoby et al (2004; e.g., for the Tropics: D' Arrigo et al (1994), Charles et al (1997), Isdale et al (1998), Guilderson and Schrag (1999), Cole et al (2000), Linsley et al (2000), Urban et al (2000), Cobb et al (2001), Tudhope et al (2001), Charles et al (2003), and Linsley et al (2004); also see Labeyrie et al (2003)]. Yet, coverage is still very limited for vast areas, particularly for the Tropics where the existing tree-ring data network is sparse but expanding (more information available online at http://www.ldeo.columbia.edu/ res/fac/trl.).…”

Analyses of instrumental data demonstrate robust linkages between decadal-scale North Pacific and tropical Indo-Pacific climatic variability. These linkages encompass common regime shifts, including the noteworthy 1976 transition in Pacific climate. However, information on Pacific decadal variability and the tropical high-latitude climate connection is limited prior to the twentieth century. Herein tree-ring analysis is employed to extend the understanding of North Pacific climatic variability and related tropical linkages over the past four centuries. To this end, a tree-ring reconstruction of the December-May North Pacific index (NPI)-an index of the atmospheric circulation related to the Aleutian low pressure cell-is presented (1600-1983). The NPI reconstruction shows evidence for the three regime shifts seen in the instrumental NPI data, and for seven events in prior centuries. It correlates significantly with both instrumental tropical climate indices and a coral-based reconstruction of an optimal tropical Indo-Pacific climate index, supporting evidence for a tropical-North Pacific link extending as far west as the western Indian Ocean. The coral-based reconstruction shows the twentieth-century regime shifts evident in the instrumental NPI and instrumental tropical Indo-Pacific climate index, and three previous shifts. Changes in the strength of correlation between the reconstructions over time, and the different identified shifts in both series prior to the twentieth century, suggest a varying tropical influence on North Pacific climate, with greater influence in the twentieth century. One likely mechanism is the low-frequency variability of the El Niño-Southern Oscillation (ENSO) and its varying impact on Indo-Pacific climate.

“…Geochemical parameters in massive coral skeletons from the Indian Ocean are well established in providing monthly to annually resolved time series of changes in SST, salinity and precipitation in the shallow oceans for up to 350 years (Fig. 1b;Charles et al 1997Charles et al , 2003Cole et al 2000;Cobb et al 2001;Kuhnert et al 2000;Zinke et al 2004aZinke et al , b, 2005Pfeiffer et al 2004Timm et al 2005;Damassa et al 2006).…”

We examine the relationship between three tropical and two subtropical western Indian Ocean coral oxygen isotope time series to surface air temperatures (SAT) and rainfall over India, tropical East Africa and southeast Africa. We review established relationships, provide new concepts with regard to distinct rainfall seasons, and mean annual temperatures. Tropical corals are coherent with SAT over western India and East Africa at interannual and multidecadal periodicities. The subtropical corals correlate with Southeast African SAT at periodicities of 16-30 years. The relationship between the coral records and land rainfall is more complex. Running correlations suggest varying strength of interannual teleconnections between the tropical coral oxygen isotope records and rainfall over equatorial East Africa. The relationship with rainfall over India changed in the 1970s. The subtropical oxygen isotope records are coherent with South African rainfall at interdecadal periodicities. Paleoclimatological reconstructions of land rainfall and SAT reveal that the inferred relationships generally hold during the last 350 years. Thus, the Indian Ocean corals prove invaluable for investigating land-ocean interactions during past centuries.

“…Similar results were found when trying to correlate the annual linear growth rates with the IOD index. Further work is needed to understand this, since according to [38], based on an analysis of a core sample from Padang Bai (to the northeast of Nusa Penida), the Bali record evidently shows unique local influences in addition to the Indonesian-wide response to ENSO.…”

“…The area is a white sandy field, at a distance of about 700 meters from the shoreline and 5 meters in depth. In order to observe the dependency of annual linear growth of corals on SST, data from Extended Reconstruction Sea Surface Temperature (ERSST) [37,38] were used. Furthermore, we also tried to analyze the relation between these annual growths and the El Nino Southern Oscillation (ENSO) and Indian Ocean Dipole (IOD) indices, since the study location is part of the area where the influence of these regional phenomena is significant.…”

Growth Rates Analysis of Porites Corals from Nusa Penida, Bali

Abstract. The annual growth of Porites coral is represented by a pair of high-and low-density bands. Environmental changes in the ambient waters influence the pattern of these annual density bands. Five colonies of Porites corals from Nusa Penida, Bali were investigated to analyze their annual linear growth rates using coral densitometry. From the analysis it was found that the annual linear growth rates of the colonies varied between 0.8924 to 1.0012 cm/yr. The trends of the colonies growth rates also varied. Two colonies showed a decreasing trend, while the others showed an increasing trend. The annual linear growth rates of most of the colonies were not influenced by sea surface temperature (SST); only one out of five colonies had a significant correlation with SST (R = 0.66, p-value < 0.05).
