Oxygen isotope records in banded corals( i¿½!80) are mainly controlled by water composition (i.e., seawater salinity) and sea surface temperature (SST) at the time of accretion

There is a 0.2 per mil offset in absolute value between the Nauru 1 and 2 records; The offset is ~0.23 per mil prior to 1980 and ~0.14 per mil after 1980

samples were reacted in vacuo in a modified autocarbonate device at 90C and the purified CO2 analyzed on a gas source stable isotope ratio mass spectrometer

we created a preliminary age model using the seasonal (doublet) structure of the respective d13C time series. The age model of Nauru 2 was then optimized through linear mapping of the coral d18O to the local precipitation record with an estimated error of 2-3 months. Over the interval where the two corals have similar sampling resolution (i.e., 1 and 2 mm density) the Nauru 1 d18O record was linearly mapped to the Nauru 2 d18O record
