The resulting spacing of Sr/Ca data remained relatively constant throughout the record, and the chronology was verified against growth band counts from the X-radiograph. After converting depth to time in Analyseries, Sr/Ca were interpolated to six equally spaced samples per year using ARAND time series analysis software [Howell, 2001], corresponding to bimonthly resolution for the length of the record.'
