- d18O (CO15ABSP01A): interpretation2_basis: ‘We found that the
correlations with d18O are 0.72 (with total pseudocoral), 0.47 (with SST
component), and 0.68 (with SSS component), p < 0.01 for all three
(Figure S1), indicating that SSS changes represent a larger fraction of
the variance in the coral d18Oanomaly signal than SST changes, as
expected from the larger magnitude of interannual SSS variations at this
site. Testing several different percent contributions of SSS and SST to
create the pseudocoral, we determined that a combination of 35% SST and
65% SSS results in the closest representation to the observed coral
d18Oanomaly values. This was calculated by creating a pseudocoral that
consisted of percent SST/SSS contributions that ranged from 100/0% to
0/100%, in increments of 5% (i.e., 100/0, 95/5, 90/10a€¦ 5/95, 0/100).
The pseudocoral consisting of 35/65% gave the highest correlation with
the measured d18O time series, which provides the percent contributions
of SST and SSS to the time series. This relationship was determined over
the period 1970a€“2007, and is limited by the length of the instrumental
SSS data set. We assume stationarity in the proportional contributions
of SST and SSS to the coral d18O signal because SSS data needed to
evaluate this assumption are lacking in the pre- 1970 period. However,
the assumption of stationarity of a proxy-instrumental relationship
developed over the instrumental time period affects all proxy-based
climate reconstructions that extend beyond the instrumental period.
Thus, lacking additional instrument data and/or another independent SST-
or SSS-only proxy there is no easy way to reduce the uncertainty of the
empirically derived proxy relationship over the calibration-verification
interval.’ has been replaced by NULL
