“…The six records spanning more than 200 yr show a distinctive cool period (&1800}1840 AD) that may be related to enhanced volcanism that occurred during this time (Crowley et al, 1997;Quinn et al, 1998). Following this cool interval, four of the six records (Panama, Vanuatu, Great Barrier Reef, Red Sea) display an Fig.…”

Corals o!er a rich archive of past climate variability in tropical ocean regions where instrumental data are limited and where our knowledge of multi-decadal climate sensitivity is incomplete. In the eastern equatorial Paci"c, coral isotopic records track variations in ENSO-related changes in sea-surface temperature; further west, corals record variability in sea-surface temperature and rainfall that accompanies zonal displacement of the Indonesian Low during ENSO events. These multi-century records reveal previously unrecognised ENSO variability on time scales of decades to centuries. Outside the ENSO-sensitive equatorial Paci"c, long-term trends towards recent warmer/wetter conditions suggest the tropics respond to global forcings. New coral paleothermometers indicate that surface-ocean temperatures in the tropical southwestern Paci"c were depressed by 4}63C during the Younger Dryas climatic event and rose episodically during the next 4000 yr. High temporal-resolution measurements of Sr/Ca and O in corals provide information about the surface-ocean hydrologic balance and can resolve the seasonal balance between precipitation and evaporation. Radiocarbon measurements in corals, coupled with ocean circulation models, may be used to reconstruct near-surface ocean circulation, past mixing rates, and the distribution of fossil fuel CO in the upper ocean. Most recently, seasonal to interannual variations in the radiocarbon of corals from the equatorial Paci"c have been linked to the redistribution of surface waters associated with the ENSO.

“…[3] This study expands upon previous coral-based climate studies offshore of Amédée Island, New Caledonia, [Quinn et al, 1996[Quinn et al, , 1998Crowley et al, 1999;Stephans et al, 2004] by examining five coral cores, three intracolony and three intercolony, for the period 1900 -1999. The goals of this study include: (1) expanding the sample resolution test to include coral Sr/Ca and higher sampling resolution, (2) extending the coral Sr/Ca reproducibility test to span the entire twentieth century, (3) assessing the stack coral Sr/Ca record with dendrochronology methods, (4) comparing coral Sr/Ca variations with in situ SST variations, and (5) verifying the coral Sr/Ca -SST calibration for a longer time interval against an independent SST data set.…”

This study contributes to the suite of Amédée Island records by 1) determining fortnightly resolved coral Sr/Ca, d 18 O, and d 13 C variations from 92-PAA1-B to compare with monthly and seasonal variations, 2) replicating monthly resolved coral Sr/Ca variations along parallel paths on 92-PAC1-A, 92-PAA1-A, and 92-PAA1-B, 3) determining monthly coral Sr/Ca variations from 92-PAA1 and 92-PAA2 for the entire twentieth century, and 4) extending the monthly resolved coral Sr/Ca record for 92-PAD1 to 1937 and 92-PAC1 to 1950.…”

[1] Coral-based climate reconstructions typically have not used multiple cores from a region to capture and replicate a climate signal largely because of concerns of coral conservation, analytical expense, and time constraints. Coral Sr/Ca reproducibility through the twentieth century was investigated using three intracolony and three intercolony coral records from the reefs offshore of Amédée Island, New Caledonia. Different sampling resolutions were examined in coral Sr/Ca (fortnightly and monthly) and d 18 O (fortnightly, monthly, and seasonally) as well as similar scale subsampling of the daily in situ sea surface temperature (SST) record. The mean coral Sr/Ca, d 18 O, and SST values do not change as a function of sampling resolution. The coral Sr/Ca signal is highly reproducible; the average absolute offset between coeval monthly Sr/Ca determinations between any two coral time series is 0.035 ± 0.026 mmol/mol (1s) ($0.65°C), which is less than twice the analytical precision of the coral Sr/Ca measurements. The stack average of the monthly coral Sr/Ca variations and monthly anomalies are significantly correlated with monthly in situ SST (1967SST ( -1992; r = À0.96 and À0.64, respectively; p < 0.05; and n = 302) and 1°grid monthly SST data product ; r = À0.95 and À0.56, respectively; p < 0.05; and n = 1198). The coral Sr/Ca-SST reconstruction exhibits interannual and decadal-timescale fluctuations that exceed those observed in the gridded SST record, which may reflect true differences between SST at a shallow reef site and those averaged over a 1°grid box or inadequacies in the methodology used to create the gridded SST product when few observations are available. A warming trend of $0.6°C is observed in the twentieth century coral Sr/Ca-SST record.
