Caribbean coral tracks Atlantic Multidecadal Oscillation
and past hurricane activity.
Geology, January 2008, Vol. 36, pp. 11-14.
doi:10.1130/G24321A.1
It is highly debated whether global warming contributed to
the strong hurricane activity observed during the last decade.
The crux of the recent debate is the limited length of the
reliable instrumental record that exacerbates the detection
of possible long-term changes in hurricane activity,
which naturally exhibits strong multidecadal variations
that are associated with the Atlantic Multidecadal Oscillation
(AMO). The AMO, itself a major mode of climate variability,
remains also poorly understood because of limited data.
Here, we present the first coral-based proxy record (d18O)
that clearly captures multidecadal variations in the AMO
and the hurricane activity. Our record, obtained from a brain
coral situated in the Atlantic hurricane domain, is equally
sensitive to variations in sea surface temperature (SST)
and seawater d18O, with the latter being strongly linked
to precipitation, by this means amplifying large-scale climate
signals in coral d18O. The SST and precipitation signals
in the coral provide the longest, thus far, continuous
proxy-based record of hurricane activity that interestingly
exhibits a long-term increase over the last century.
As multidecadal SST variations in this region are closely
related to the AMO, this study raises new possibilities
to extend the limited observations and to gain new insights
into the mechanisms underlying the AMO and long-term
hurricane variations.
STUDY NOTES: Coral stable isotope (d18O) data at monthly and annual resolution
for the last 90 years from the Los Roques Archipelago, Venezuela.
Core Roq6 was collected from a Diploria strigosa coral specimen
in December 2004.
Sampling location near Cayo Sal, Los Roques Archipelago, Venezuela:
11.77°N, 66.75°W, 2m water depth
