Impact of the 1998 bleaching event on d18O records of Okinawa corals.
Marine Ecology Progress Series, Vol. 314, pp. 127-133.

Oxygen isotope compositions of Porites sp. were measured in order
to examine the effect of the 1998 bleaching event on the skeletal
record of 6 neighboring colonies from Sesoko Island, Okinawa, Japan.
A d18Oc-SST dependency of 0.18‰/°C was calculated using a 10 yr
record, well within accepted calibrations. The skeleton portion
accreted during 1998 exhibited 0.3‰ enrichment in d18O, which differs
from the depleted values expected during abnormally high SST conditions.
Growth rate changed significantly during the bleaching event,
and its manifestation in skeletal d18O masked the temperature signal.
The d18O variance among the 6 colonies was noticeably higher during
1998 in comparison with 1997 and 1999. A residual analysis revealed
that 75% of the inter-annual variation of the d18O record is explained
by variation in annual extension rate. The increase in d18O variance
is proposed as a novel indicator for stressful environmental conditions.
STUDY NOTES: Coral stable isotope (d18O and d13C) data at sub-monthly resolution
from 6 corals collected near Sesoko Island, Okinawa, Japan.
Data span the 1998 bleaching event.
