inferredMaterial: seawater
integrationTime: 12-Jun
integrationTimeBasis: A first chronology was developed based on the density bands evident in the X-rays, which are presumed to represent one year of growth (Figure 4). The age model was then refined using the strong annual cycle in coral d18O (Figures 5 and 6). The heaviest isotopic value in any given year was assigned to 1 September, which is, on average, the coldest month. We then interpolated linearly between these anchor points into 12 equidistant points per year for the monthly, and 6 points per year for the bimonthly resolved series
