integrationTimeBasis: 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

basis: The observed d180 decrease that occurs between 1952 and 1995 (-0.5 permil) equates to a -2.5C warming, an -2 permil decrease in salinity [Fairbanks et al., 1997], or some combination thereof. Instrumental and reconstructed SSTs of a slightly larger region [Reynolds and Smith, 1994; Kaplan et al., 1998] do show an -0.5C increase which can only be partly responsible for the observed trend in the coral records. Moreover, the shift does not appear to be a consequence of a change in the isotopic composition of precipitation in the region [Rozanski et al., 1992].
