variableName: d18O
units: permil
description: carbonate
basis: Interannual variability in the MS01 coral d18O for 1910a€“ 1997 is clearly dominated by changes in d18Ow because SSTs reconstructed from the coral d18O span 5C [Gagan et al., 1998], while the GOSTA SST range is only 1C (Figure 1). Comparison of local SSTs and rainfall with the coral d18O record shows that d18O increases when SST and rainfall decrease during El NinEœo events
