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
