Sr/Ca and d18O in a fast-growing Diploria strigosa coral:
Evaluation of a new climate archive for the tropical Atlantic.
Geochem. Geophys. Geosyst., 7, Q10002, doi:10.1029/2006GC001347.
This study provides the first monthly resolved, 41-year record
of geochemical variations (d18O and Sr/Ca) in a fast-growing
Diploria strigosa brain coral from Guadeloupe, Caribbean Sea.
Linear regression yields a significant correlation of coral
Sr/Ca (d18O) with instrumental sea surface temperature (SST)
on both monthly and mean annual scales (e.g., r = ?0.59 for
correlation between Simple Ocean Data Assimilation (SODA) SST
and Sr/Ca, and r = -0.66 for d18O; mean annual scale, p < 0.0001).
The generated coral Sr/Ca (d18O)-SST calibration equations
are consistent with each other and with published equations
using other coral species from different regions. Moreover,
a high correlation of coral Sr/Ca and d18O with local air
temperature on a mean annual scale (r = -0.78 for Sr/Ca;
r = -0.73 for d18O; p < 0.0001) demonstrates the applicability
of geochemical proxies measured from Diploria strigosa corals
as reliable recorders for interannual temperature variability.
Both coral proxies are highly correlated with annual
and seasonal mean time series of major SST indices in the
northern tropical Atlantic (e.g., r = -0.71 for correlation
between the index of North Tropical Atlantic SST anomaly
and Sr/Ca, and r = -0.70 for d18O; mean annual scale, p < 0.001).
Furthermore, the coral proxies capture the impact of the
El Niño-Southern Oscillation on the northern tropical Atlantic
during boreal spring. Thus fast-growing Diploria strigosa corals
are a promising new archive for the Atlantic Ocean.
STUDY NOTES: Coral stable isotope (d18O) and Sr/Ca data at monthly and annual
resolution for the last 104 years from Guadeloupe, Caribbean Sea.
Core Gua1 was collected from a Diploria strigosa coral specimen
in April 2000.
Note that for the comparison of coral proxy time series with climate
indices, we have filled the 3-year gap (October 1978 to October 1981)
in the coral proxy time series with calculated coral d18O values,
that have been generated based on the coral d18O-SST calibration
equations obtained through linear regression with SST data
(for detailed calibration equations see Hetzinger et al. (2006);
Table 2 therein).
